+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+
+ perf: beginning of a performance testsuite
+
+ Some tests in the Automake testsuite already aims only at verifying
+ the performance, rather than the correctness, of some operations.
+ Still, they are somewhat shoehorned and forced into the PASS/FAIL
+ framework (say, with the 'ulimit' shell builtin used to verify some
+ operation doesn't take up too much time or memory), but that is
+ conceptually a stretch, and has already caused problems in practice
+ (see automake bug#11512 for an example).
+
+ So we start moving the "performance tests" out of the testsuite proper,
+ and make them run only "on demand" (when the user exports the variable
+ 'AM_TESTSUITE_PERF' to "yes"). Ideally, we should provide those tests
+ with a custom runner/driver that measures and displays the relevant
+ performance information, but doing that correctly and with the right
+ APIs is definitely more difficult, so we leave it for a later step
+ (an hope we'll take such a step eventually).
+
+ * t/cond29.sh: Move ...
+ * t/perf/cond.sh: ... here, and adjust.
+ * t/testsuite-recheck-speed.sh: Move ...

+ * t/list-of-tests.mk (perf_TESTS): New variable, listing the tests in
+ the 't/perf' directory.
+ (handwritten_TESTS): Adjust.
+ * defs: Skip any tests in the 't/perf/' subdirectory unless the
+ 'AM_TESTSUITE_PERF' variable is set to "yes" or "y".
+ * .gitignore: Update.

+ aclocal: declare function prototypes, do not use '&' in function calls
+
+ This change will also fix automake bug#11543 (from a report by Matt

+ any actual function definition (but omit the prototype for the dynamically
+ generated '&search' function). Add prototypes to any function definition.
+ Remove '&' from function invocations (i.e., simply use "func(ARGS..)"

+
+ The use of configure.in as Autoconf input has been deprecated for a
+ very long time in the Autoconf documentation, and the next version of
+ Autoconf (2.70) will start warning about it ar runtime as well (see
+ commit 'v2.69-4-g560f16b' or 2012-05-23, "general: deprecate
+ 'configure.in' as autoconf input", in the Autoconf's git repository).

+
+ [ng] maintcheck: some tweaks and fixlets
+
+ * syntax-checks.mk (sc_no_brace_variable_expansions): Do not complain
+ about ${MAKEVAR} usages in comments: they might be legitimate. This
+ change is not strictly required for mainline automake, but will help
+ in the Automake-NG branch.
+ * sc_tests_here_document_format: Relax a bit, so that usages like
+ "cout << "string" << endl;" in the test scripts (usages which can be
+ used in here documents defining C++ sources) are not flagged as uses
+ of bad delimiters for here documents. This change is not strictly
+ required for mainline automake, but will help in the Automake-NG
+ branch, and will anyway be more future proof w.r.t. possible future
+ testsuite additions.
+ (sc_tests_Exit_not_exit): Do not whitelist lines containing $PERL
+ explicitly (that was only required for one test); instead ...
+ * t/ext2.sh: ... use "exit (1)" instead of "exit 1" in the perl
+ invocation of the guilty script.
+

+
+2012-05-19 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Merge branch 'ylwrap-line-filename' into maint

+
+2012-05-18 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tests: use 'parallel-tests' Automake option by default
+
+ This will help our transition from 'serial-tests' to 'parallel-tests'
+ as the default test suite driver enabled by a TESTS assignment in the
+ input Makefile.am. Note that that change of default will only take
+ place in master, though.
+
+ * defs: Pass the 'parallel-tests' option to the AM_INIT_AUTOMAKE
+ invocation in the created 'configure.ac' stub, unless the variable
+ 'am_serial_tests' is set to "yes". Don't pay attention anymore to
+ the 'am_parallel_tests' variable, that's obsolete now.
+ * defs-static.in: Warn if the 'am_serial_tests' variable is set in the
+ environment; conversely, don't warn anymore about 'am_parallel_tests'
+ being set in the environment.
+ * Makefile.am (AM_TESTS_ENVIRONMENT): Nullify the 'am_serial_tests'
+ variable instead of the now-obsolete 'am_parallel_tests' one.
+ * syntax-checks.mk (sc_tests_obsolete_variables): Also warn against
+ uses of 'am_parallel_tests', which is now deprecated in favor of
+ 'am_serial_tests'. Similarly, if a use of 'parallel_tests' is seen,
+ suggest using 'am_serial_tests' instead, not 'am_parallel_tests'.
+ * gen-testsuite-part: Now that we use the 'parallel-tests' by default
+ in our tests, we need to completely change the logic and semantics of
+ generation of sibling tests for those tests that check the Automake
+ generated testsuite harness itself. Do that, and give a complete
+ explanation of the new logic and semantics in the relevant comments.
+ * t/README: Update.
+ * Lots of test cases: Adjust.
+
+2012-05-17 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ doc: fix location of Automake's own test-suite.log file
+
+ * doc/automake.texi (Reporting Bugs): The global testsuite log of

+ in the file 'tests/test-suite.log'. Adjust accordingly.
+
+2012-05-16 Nikolai Weibull <now@bitwi.se> (tiny change)
+ Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ ylwrap: preserve subdirectories in "#line" munging
+
+ If Automake is used in non-recursive mode and one of the inputs is a
+ yacc file, for example, "src/grammar.y", ylwrap will remove too many
+ directories from the output file when it adjusts the paths in it.
+ This results in #line directives referring to "grammar.y" instead of
+ "src/grammar.y".
+
+ This is a result of $input_rx simply taking all the directory
+ components of the absolute input path and removing them.
+
+ One solution is to store the path passed to ylwrap and replace
+ $input_rx with it. This is what we do.
+
+ Suggestion and initial patch (without tests) by Nikolai Weibull:
+ <http://lists.gnu.org/archive/html/automake/2012-05/msg00013.html>
+ Final patch by Stefano Lattarini.
+
+ * lib/ylwrap ($input_sub_rx): New.
+ When munging the #line directives, substitute '$input_rx' with it,

+ to /bin/zsh4). This is required because our testsuite does not
+ support older versions of Zsh, and that was causing the test to fail
+ in the setup just described.

+ m4: prepend m4 builtins with "m4_"
+
+ The comments in 'lib/autoconf/autoconf.m4' from Autoconf 2.69 read:
+
+ We discourage the use of the non prefixed macro names: M4sugar maps
+ all the builtins into 'm4_'. Autoconf has been converted to these
+ names too. But users may still depend upon these, so reestablish
+ them.
+
+ Alas, in our init.m4 files, we were still using m4 builtins without
+ prefixing them with "m4_". Not nice for a package that is one of the
+ major clients of Autoconf, and an integral part of the GNU Autotools!
+
+ Fix the issue.
+
+ * m4/init.m4 (AM_INIT_AUTOMAKE): Use 'm4_define' and 'm4_defn' instead
+ of 'define' and 'defn'.

+ docs: fix clumsy grammar in the scripts-based testsuite chapter
+
+ * doc/automake.texi (Scripts-based Testsuites): "We'll have later" is

+ formulated.

+
+ tests: use append mode to capture parallel make output
+
+ This should fix the spurious failure reported in automake bug#11413.
+
+ This is due to the fact that the redirected output of parallel make
+ can racily loose lines. For example, if GNU make (3.82) is run on
+ a Makefile like this:
+
+ all = 0 1 2 3 4 5 6 7 8 9
+ default: $(all)
+ $(all):
+ @sleep 0.$$(($RANDOM % 10)); echo $@
+
+ and has its standard output redirected in overwrite-mode to a regular
+ file, it looses a line of that output every 15 runs or so on a Fedora
+ 17 system with 64 ppc64 cores and Linux 3.3.1. Redirection in append
+ mode does not suffer of this problem.
+
+ See also similar commit 'Release-1-10-280-g6426999' of 2009-03-10,
+ "Use append mode to capture parallel test output", which tackled a
+ similar problem for 't/parallel-tests3.sh' and 't/lisp8.sh'.
+
+ * t/tap-more.sh: Use append mode for output from "make -j", to avoid
+ dropped lines.

+
+ color-tests: coloring can be forced on non-ANSI terminals as well
+
+ Before this change, colorization of testsuite output was suppressed
+ whenever the terminal was recognized to be a "dumb" one, incapable
+ of handling ANSI coloring (i.e., when the environment variable TERM
+ had a value of "dumb"). This happened even when the AM_COLOR_TESTS
+ variable was set to a value of "always".
+
+ Such a behaviour was suboptimal and slightly confusing; in fact, if
+ a user wants to force coloring of testsuite output that is being
+ redirected to a regular file, he should be able to do so even if his
+ terminal is not capable of handling ANSI colors -- in fact, such
+ terminal wouldn't be involved with the testsuite output in any way,
+ so why should it be allowed to influence it?
+
+ Thus, we now enable coloring of test output whenever AM_COLOR_TESTS
+ is set to "always", irrespective of the value of the TERM environment
+ variable.
+
+ * NEWS: Update.
+ * lib/am/check.am [%?COLOR%] (am__tty_colors): Activate colorization
+ of testsuite output whenever AM_COLOR_TESTS has the value of "always".
+ * t/ax/tap-summary-aux.sh: Export the TERM environment variable to
+ "dumb" when forcing colorization of the testsuite output; this should

+
+ fixup: avoid unconditional re-bootstrapping on "make dist"
+
+ Since our 'bootstrap' script is distributed, the 'distdir' target depends
+ on it. But in our GNUmakefile, we also have a 'bootstrap' target declared
+ .PHONY, which when called re-bootstrap the Automake distribution. Thus,
+ whenever we run "make dist", GNU make sees it must remake the 'bootstrap'
+ target (as it is a dependency of the 'distdir' target), and thus ends up
+ re-bootstrapping all the package (because of the .PHONY 'bootstrap' target
+ in GNUmakefile).
+
+ We fix this issue by renaming our bootstrap script to 'bootstrap.sh'.
+

+
+ bootstrap: add convenience make target
+
+ Dependencies in the Automake build system are not completely specified
+ (see for example the commit log of recent commit 'v1.12-10-gab14841',
+ "build: avoid too greedy rebuilds in the testsuite"). In fact, some of
+ them cannot even be; for example, Makefile is generated at configure
+ time from Makefile.in, which should be regenerated by our bleeding-edge
+ automake script, which is generated by out Makefile -- specifying the
+ complete chain of dependencies here would bring to a circular dependency
+ issue.
+
+ For this reason, before testing or deploying a change, we are often
+ forced to perform a full re-bootstrap of the Automake package, to ensure
+ all our files are actually up-to-date. Until now, this has to be done
+ manually, thus causing wasted keystrokes and more possibilities of error.
+
+ With this change, we introduce a new 'bootstrap' make target to
+ automatize all the (easy) steps of this re-bootstrapping (plus some
+ minor bells & whistles since we are at it).
+
+ * GNUmakefile: Rewrite to allow an easy bootstrapping and clean rebuild

+ maint: don't use "union" merge driver for NEWS anymore

+ merge conflicts in NEWS. For further discussion, see:

+
+ build: avoid too greedy rebuilds in the testsuite
+
+ The autogenerated makefile fragment 't/testsuite-part.am' used to depend
+ on the list of *all* the hand-written files. This was technically correct,
+ since that makefile fragment was (and still is) generated by the script
+ 'gen-testsuite-part', which scans all the hand-written files to detect
+ implicit dependencies and to decide for which tests a further wrapper test
+ should be generated.
+
+ However, the presence of such a dependency implied that, whenever *any*
+ test case was modified (no matter how slightly), the 't/testsuite-part.am'
+ file was rebuilt, and since that is included by our 'Makefile.am', the
+ 'Makefile.in' file was rebuilt as well by automake. In order to do so,
+ automake scanned our 'configure.ac' file, which requires the latest
+ Autoconf version (2.69 at the time of writing), and the casual user can
+ easily lack that on his machine (and that should be allowed, as automake
+ currently supports any autoconf version >= 2.62).
+
+ The described situation could hinder in-field testing or debugging by
+ users (even experienced ones) that are not automake developers; see for
+ example automake bug#11347.
+
+ So we drop the explicit dependency of 't/testsuite-part.am' on the
+ hand-written test cases. (As an aside, note that this has already
+ been done in Automake-NG, albeit for other reasons; see the commit
+ 'v1.11b-129-g1690aca' of 2012-04-23, "[ng] build: define $(TESTS)
+ through a wildcard").
+
+ This is not a serious regression in the faithfulness of the Automake
+ build systems, since it unfortunately already had several undeclared
+ dependencies; e.g., 'Makefile.in' should depend on the automake script,
+ and 'aclocal.m4' should depend on the aclocal script (but this isn't
+ possible, as it would mean that distributed files depend on ones generated
+ at make time). Similarly, 'Makefile.in' should depend on some of the
+ 'lib/am/*.am' files, but does not.
+
+ Currently, the workaround to get a faithful and correct rebuild is to run
+
+ ./bootstrap && ./config.status --recheck && make clean all
+
+ and the present commit does not change that.
+
+ * Makefile.am ($(srcdir)/t/testsuite-part.am): Don't depend on
+ 't/list-of-tests.mk' nor on '$(handwritten_TESTS)' anymore.
+ ($(generated_TESTS)): Likewise, and don't depend on 'Makefile.am'
+ either.

+ From a report by Bruno Haible in automake bug#1193. This change should

+ * NEWS: Update.

+
+ Fixes automake bug#11252.
+
+ When a developer experience one or more failures in the testsuite, a good

+ the testsuite failures previously experienced, and then run "make check"
+ to verify that the change has not introduced any new failure or regression.
+
+ Unfortunately, this apparently natural workflow couldn't have worked until
+ now, since the Automake-provided 'recheck' target (which didn't depend on
+ 'all') wouldn't have causes the program to be recompiled, and the failed

+
+ build: generate doc/*.1 files; include help2man
+
+ This change is required to avoid making a distributed file depend
+ on a generated (non-distributed) one. The preceding change
+ introduced one such dependency, with the distributed doc/*.1
+ depending on the generated aclocal and automake files. Here,
+ we avoid the problem by generating the doc/*.1 files rather than
+ distributing them.
+
+ * doc/help2man: New file, version 1.37.1.
+ * Makefile.am (EXTRA_DIST): Add doc/help2man.
+ (man1_MANS): Rename from $(dist_man1_MANS). Remove $(srcdir) prefix.
+ (CLEANFILES): Add these files here, rather than to
+ $(MAINTAINERCLEANFILES), since we are no longer distributing them.
+ (update_mans): Use doc/help2man, not $(HELP2MAN).

+
+ build: avoid parallel build failures
+
+ A parallel build would fail when two concurrent sub-make processes
+ tried to build lib/Automake/Config.pm. The loser would complain that
+ grep: lib/Automake/Config.pm-t: No such file or directory
+ chmod: cannot access `lib/Automake/Config.pm-t': No such file or\
+ directory
+ make[1]: *** [lib/Automake/Config.pm] Error 1
+ * Makefile.am (update_mans): Don't build lib/Automake/Config.pm here.
+ Instead, depend on it from the two rules that use it:
+ ($(srcdir)/doc/aclocal-$(APIVERSION).1): Depend on it.
+ ($(srcdir)/doc/automake-$(APIVERSION).1): Likewise.
+
+ [ Note that technically, the above is incorrect, since it makes those
+ distributed doc/*.1 files depend on generated aclocal and automake.
+ That problem is addressed by the following commit. ]
+
+ However, that was not enough, since even then, a parallel build
+ would still fail, now with this:
+
+ help2man: can't get `--help' info from automake-1.11a
+ Try `--no-discard-stderr' if option outputs to stderr
+ make: *** [doc/automake-1.11a.1] Error 1
+
+ a subsequent "make -j3" would create the missing file.
+ That was because help2man would invoke t/wrap/aclocal.in and
+ t/wrap/automake.in, each of which would require aclocal and
+ automake, yet those two files weren't guaranteed to be created.
+ Add explicit dependencies:
+ ($(srcdir)/doc/aclocal-$(APIVERSION).1): Depend on aclocal.
+ ($(srcdir)/doc/automake-$(APIVERSION).1): Depend on automake.

+
+ This change fixes automake bug#11185.
+
+ The commit v1.11-2058-g6f4b08d of 06-03-2012, "tests: explicitly
+ state that our lexers do not require unistd.h" has broken the tests
+ 'lex-clean-cxx.test' and 'lex-depend-cxx.test' on Solaris, where lex
+ is not flex and does not understand the "%option never-interactive"
+ directive. Remove the use of this directive, resorting to defining
+ a dummy 'isatty()' function instead to keep the flex-generated tests
+ able to compile also on MinGW/MSYS.
+
+ * tests/lex-clean-cxx.test (parsefoo.lxx): Define a dummy 'isatty()'

+
+ When we (soon) convert the Automake testsuite to a non-recursive

+ texinfo: warn about future use of '--tidy'
+
+ Starting from the next major release of Automake (likely 1.13) we
+ want to start passing the '--tidy' option to texi2dvi and texi2pdf
+ invocations, so that auxiliary TeX-generated files can be kept
+ around (thus speeding up rebuilding of DVI and PDF output) without
+ cluttering the build directory too much.
+
+ Since the '--tidy' option was introduced in Texinfo 4.9 (as
+ documented in the Texinfo distribution's NEWS file), this also
+ means that Makefiles generated by future Automake versions will
+ require at least that version of Texinfo (at the time of writing
+ four years and nine months old).
+
+ The users should be warned about the planned behavioral change
+ and the new version requirement it will entail.
+
+ See also automake bug#11146.
+
+ * NEWS (Planned Backward Incompatibilities): Add entry about use

+
+ texinfo: don't clutter the builddir when using modern texi2dvi
+
+ In modern versions of texi2dvi (at least since version 1.135, which
+ comes with Texinfo 4.13) the '-o' option does not imply anymore the
+ '--clean' option. As a consequence, lots of TeX-generated auxiliary
+ files are now left in the build directory by the 'pdf', 'ps' and
+ 'dvi' rules.
+
+ This is especially annoying with non-recursive setups having the
+ '.texi' files in a subdirectory, as in:
+
+ info_TEXINFOS = doc/foo.texi
+
+ In this case, the stray auxiliary files are left in the top build
+ directory (since TeX is run from there). See for example:

+ acinstall: remove, it has never been really used
+
+ Accordingly to the git history (see for example the 'README-alpha'
+ in commit 'Release-1-1e-39-g9beb4ec' of 06-10-1996), the 'acinstall'
+ script should have been used to install m4 files for aclocal. The
+ comments in this script report that "... A script is needed to do
+ this because we want to do serial-number checking; newer versions
+ of macro files should always be preferred".
+
+ But the 'acinstall' script has never been really used: for example,
+ the entry "actually use acinstall program" was removed (unfixed)
+ from the TODO file in commit 'Release-1-1k-12-g1201405' of
+ 08-12-1996, and the only citation of 'acinstall' in the manual was
+ removed in commit 'Release-1-1l-37-g128c3d7' of 19-03-1997, and
+ never added back. In addition, the last non-trivial edit to the
+ script (that is, besides updates to the copyright notice) dates
+ back to 1996.
+
+ More importantly, now that aclocal supports the ACLOCAL_PATH
+ environment variable, installing m4 files directly in the
+ system-wide acdir is discouraged, and better left only to
+ distros' package managers (which already have their own way to
+ do so, with which third-party build systems should not directly
+ meddle).
+
+ So we just remove the 'acinstall' script.

+ depcomp: support tcc (Tiny C Compiler)
+
+ This change fixes automake bug#11007.
+
+ Since git commit 0c928da9 of 21-06-2010, "tcc: Draft suppoprt for
+ -MD/-MF options" (sic, with typo in summary line), tcc has supported
+ automatic dependency generation with a command-line interface
+ similar to what old (pre-8.0) Intel compilers did. This caused
+ Automake-generated code for automatic dependency tracking to
+ recognize tcc dependency style as "icc". However, the format of
+ the dependency files generated by tcc is apparently different enough
+ from that of icc to cause spurious failures in the post-processing
+ operated by our 'depcomp' script on such files.
+
+ The failure was exposed with the development version of tcc 0.9.26
+ (as installed with debian package "tcc 0.9.26~git20120104.83d") by
+ test case 'depcomp-auto.tap' (available only in the master branch).

+
+ tests: workaround for automatic linker determination and conditionals
+
+ See automake bug#11089.
+
+ Automake is not very smart in automatically determining the command
+ to be used to link a program whose source files' languages are
+ conditionally defined. For example, an input like:
+
+ if HAVE_CXX
+ foo_SOURCES = more.c++
+ else
+ foo_SOURCES = less.c
+ endif
+
+ will cause the build rules for 'foo' to *unconditionally* use the
+ C++ compiler for linking, even when the 'HAVE_CXX' conditional
+ evaluates to false (which might mean that no C++ compiler is
+ available).
+
+ This behaviour is not really correct, but it's easy enough to work
+ around, and it's only relevant for fringe use cases (at best). So
+ let's just test that the workaround really works.

+ maint: update TODO file
+
+ We don't have to make creation of $(foodir) conditional when
+ foo_PRIMARY is conditionally defined; that has been solved in
+ a more sweeping way by commit v1.11-759-g368f1c4 of March 18,
+ which solved bug#11030 and bug#10997.
+
+ The "check" target already depends on the "all" target.
+
+ Remove comment "investigate problems with conditionally defined
+ libraries"; it is aimed at automake 1.5 (!) and too terse and old
+ to be useful now.
+
+ Remove the 12 years old suggestion that "distcheck should make sure
+ that each file that uses _() is listed in POTFILES.in"; this is
+ handled by gnulib-provided syntax check 'sc_po_check' already today.
+
+ Don't tell to "Run automake before libtool"; automake does not
+ automatically run libtool anymore today.
+
+ Remove hint about the possibility to "rewrite automake in guile" or
+ "add a GUI": we are not going to do so.
+
+ The automatic de-ANSI-fication feature has already been remove, so
+ no need to suggest its potential removal in the future.
+
+ Remove reference to a prospective "cvs" option that could add some
+ cvs-specific rules. First of all, CVS is falling out of use today.
+ Secondly, and most to the point, instead of guessing which VCS
+ is going to be most popular and try to hack support for it into
+ automake, we should leave it to developer-specific makefile
+ fragments offered by projects like Gnulib to provide such rules
+ (they are already doing so with succcess).
+
+ About DOS support: it should actually be dropped, not extended.
+
+ Add link about Karl Berry's proposal of preferring HTML over Info
+ documentation installed in the local system:
+ <http://lists.gnu.org/archive/html/texinfo-devel/2012-03/msg00018.html>
+
+ Remove items about "beautification" of output Makefile.in; they
+ are pretty obvious, and mostly noise (after all, everybody prefers
+ clean output where possible). Leave it to any developer doing
+ future refactorings to find out low-hanging and/or high-impact
+ optimizations and beatifications of the generated Makefiles.
+
+ Remove item about internationalization: we're not going to
+ implement it.
+
+ Remove an item explicitly marked as "not that it matters".
+
+ The order of files in a distribution tarball does not really
+ matter, nobody has ever complained about it, so do not worry
+ about it.
+
+ Remove the suggestions about allowing hierarchy of dirs to share
+ one aclocal.m4 and about printing full file name of Makefile.am
+ or configure.in when giving error, in order to help very large
+ trees: nobody has ever complained about the current behaviours,
+ so no real need to change them.

+
+ install: don't create empty dirs when an empty 'foo_PRIMARY' is used
+
+ Fixes automake bug#11030 and bug#10997.
+
+ An empty declaration of "foo_PRIMARY" in a Makefile.am used to
+ cause the generated install rules to create the directory $(foodir)
+ anyway, even if nothing was to be installed there.
+
+ While this could be seen as a convenient way to create a $(foodir)
+ directory upon "make install" (respecting $(DESTDIR) settings and
+ such), it also caused problems with conditionals; for example, an
+ input of:
+
+ if FALSE
+ pgkdata_DATA = something
+ endif
+
+ caused the generated install rules to unconditionally create the
+ $(pkgdatadir) directory (see automake bug#10997).
+
+ Also, a user wanting to create an empty directory upon installation
+ can easily do so with a custom install hook, as in:
+
+ installdirs-local:
+ $(MKDIR_P) $(DESTDIR)$(foodir)
+ install-data-hook: installdirs-local
+
+ On the other hand, the old behavior of "always create $(foodir),
+ even if 'foo_PRIMARY' is empty" was harder and more tricky to
+ override.
+
+ Thus, from now on, an empty declaration of "foo_PRIMARY" will not
+ cause the directory $(foodir) to be created upon "make install"
+ anymore.

+
+ Older GNU m4 versions (e.g., 1.4.6) did error reporting at the end

+ tests: avoid spurious failures in get-sysconf.test
+
+ This change fixes the last bit of automake bug#10866.
+
+ * tests/get-sysconf.test: When Homebrew spawns a build, even if
+ from a project's VCS, it stages the files in a new temporary
+ directory, instead of building directly from a VCS checkout.
+ This behaviour was causing a spurious failure in this test, which
+ expected to find either a ChangeLog file or a .git directory in
+ the source directory (the former happening when the test was run
+ from a distribution tarball, the latter when it was run from a
+ git checkout). The Homebrew issue shows that these expectations
+ are not truly warranted, so relax the test to just give a warning,
+ not a failure, in case they do not hold. Since we are at it, fix
+ an unrelated weakness in the displaying of the git log, which
+ could have failed when the builddir was not a subdirectory of the
+ srcdir.

+ Merge branch 'msvc' into maint
+
+ This merge remedies the confusing situation that some changes
+ destined for both the master branch and the release branch (a.k.a.
+ branch-1.11) currently needs to be made on the non-obvious msvc
+ branch and not on the more natural maint branch. This has caused
+ a seemingly endless string of less than optimal commits.
+
+ The reason for the confusion stems from the fact that the changes made
+ on the msvc branch became too radical and was considered only suitable
+ for the master branch, and was thus written in a form suitable for
+ master and then merged there. Later, the msvc branch was merged
+ directly into branch-1.11, in order to rush the new features to the
+ market and to keep the released scripts (lib/ar-lib, lib/compile and
+ lib/depcomp) consistent with those on the master branch. However,
+ some changes had to be made to the features added by the msvc branch
+ in order for them to fit the requirements of branch-1.11, notably that
+ the warnings issued in the extra-portability class cannot be enabled
+ by -Wall in the 1.11.x maintenance releases.
+
+ In retrospect, it would have been better to not merge msvc directly
+ into branch-1.11, but instead do it via the maint branch (followed up
+ with a dummy merge from maint into master) the moment it was decided
+ that the msvc changes should make it into branch-1.11.
+
+ All in all, this merge is going to affect neither the master branch
+ nor branch-1.11, since it is followed up with dummy merges masking all
+ changes. The merge is made to maintain the sanity of the poor
+ developers, who wishes to once again have a working maint branch.

+ tests: do not clobber the $CC set by AM_PROG_CC_C_O
+
+ If $CC is originally a losing compiler, AM_PROG_CC_C_O will

+ maint: drop 'Automake::Struct' module
+

+ honest to just require it throughout. And anyway, we were already

+
+ self checks: relax tests on cleanup
+
+ Some find(1) implementations have problems operating recursively on
+ directories having subdirectories with null permissions, even when
+ the permissions of such subdirectory should be fixed by find before
+ it descends into them; for example, with this setup:
+
+ % mkdir a a/b
+ % chmod 000 a/b
+
+ a command like this:
+
+ % find a -type d ! -perm -700 -exec chmod u+rwx '{}' ';'
+
+ fails with this diagnostic on MacOS X 10.7:
+
+ find: a/b: Permission denied
+
+ and with this diagnostic on Solaris 10:
+
+ find: cannot read dir a/b: Permission denied
+
+ The problem is that our self checks were simply demanding too much
+ from our cleanup trap: our tests never use subdirectories with null
+ permissions, so it doesn't matter if the cleanup trap fails to
+ handle those. Just relax the self checks to avoid such useless
+ testsuite noise.
+
+ * tests/self-check-cleanup.tap: Only try directories missing
+ write permissions, not with null permission. That should be
+ enough for our usages.

+ spy: "rm -f" and "rm -rf" without args are portable
+
+ According to recent testing by Eric Blake, it seems that all
+ non-museum rm(1) implementations don't complain if called without
+ file operands, *if* the '-f' option is used. This behaviour will
+ likely be mandated by future versions of the POSIX standard as
+ well.
+
+ We'd like to start assuming this rm(1) behaviour in future Automake
+ releases, in order to simplify some automake-provided cleanup rules.
+ So, for the moment, we add a new "spy" test in our test suite, to
+ try ensuring that all the rm(1) implementation we encounter "in the
+ wild" truly behaves as expected in this regard.
+
+ For more references, see this discussion on the bug-autoconf list:
+ <http://lists.gnu.org/archive/html/bug-autoconf/2012-02/msg00002.html>
+ which sprang from coreutils bug#10819:
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10819>
+ and brought to the POSIX issue#542:
+ <http://austingroupbugs.net/view.php?id=542>
+ which has been accepted and will ensure that future version of the
+ POSIX standards will mandate that 'rm' shouldn't complain if called
+ without file operands, when the '-f' option is in use.
+

+ least since autoconf 2.50).
+

+ automake: new option 'serial-tests'
+
+ Currently, automake offers a 'parallel-tests' option to enable the
+ use of the parallel testsuite harness in the generated Makefiles,
+ but no option to explicitly state the intention of using the older
+ serial testsuite driver (which is currently the default).
+
+ This makes the parallel test harness seems like a second-class
+ citizen (while actually it should be the other way around); more
+ importantly, it will prevent us from making the parallel harness
+ be the default one in future automake versions, since the users
+ of the serial harness would then have no way to instruct automake
+ to continue using it.
+
+ We solve all of this by introducing a new 'serial-tests' option.

+ depcomp tests: fix up today's botched commit
+
+ Today's commit 'v1.11-1959-g0699a84' has caused the generated
+ 'depcomp*.tap' tests to call the 'plan_' function *before* it is
+ defined, and has also caused the extra checks required for better
+ libtool coverage to be run only when libtool is *not* in use,
+ rather than the other way around. Fix this mess.
+
+ Report by Peter Rosin.
+
+ * tests/gen-testsuite-part: Include './defs' in the generated

+ tests: avoid ksh bug for wildcards in EXTRA_DIST
+
+ Some shells, like NetBSD 5.1 /bin/ksh, have a bug that causes
+ wildcards resulting from an unquoted parameter expansion not to
+ be expanded as expected in some cases:
+
+ $ touch a b c d
+ $ /bin/sh -c 'var="[ab]" && echo $var' # As expected.
+ a b
+ $ /bin/ksh -c 'var="[ab]" && echo $var' # Oops.
+ [ab]
+ $ /bin/ksh -c 'var="?" && echo $var' # But this as expected.
+ a b c d
+
+ This was causing a failure in our testsuite. Work around that.

+ * tests/extra10.test: Similarly, enhance coverage by also running
+ "make distcheck", and fix a minor bug in the process. But continue
+ using a "bare" wildcard expression in EXTRA_DIST, without involving

+ tests: truly use Lex and Yacc selected by configure
+
+ When 'yacc-work' was merged into 'yl-work-for-master' in commit
+ v1.11-1910-ge6c40d4 (12-02-2012), the values for $YACC and $LEX
+ stopped being substituted directly by config.status, and started
+ being substituted by a Makefile rule using the contents of the
+ $(YACC) and $(LEX) makefile variables.
+
+ Unfortunately, our configure.ac was calling AM_SUBST_NOTMAKE on
+ 'YACC' and 'LEX' (see commit v1.11-284-g34ca92b of 29-01-2011,
+ "tests: don't define YACC and LEX in the Makefiles", for a
+ rationale), so that the $(YACC) and $(LEX) in the Makefile simply
+ hold the default make-provided values (that is, "yacc" and "lex"
+ respectively), independently of what yacc and lex programs were
+ defined at configure time.
+
+ Apart from reducing coverage and creating confusion, this behaviour
+ also caused spurious failures on systems lacking a yacc and/or lex
+ programs.
+
+ Problem reported by Peter Rosin. References:

+ tests: fix spurious failures due to missing 'yywrap()' function
+
+ The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
+ the "lex library" expected to provide a 'yywrap' function (function
+ which is required to link most lex-generated programs). On the
+ contrary, when all the link attempts (i.e., with '-ll' and '-lfl')
+ fail, configure declares that no lex library is needed, and simply
+ proceeds with the configuration process -- only for the build to
+ possibly fail later, at make time.
+
+ This behaviour is intended; the Autoconf manual reads:
+
+ You are encouraged to use Flex in your sources, since it is
+ both more pleasant to use than plain Lex and the C source it
+ produces is portable. In order to ensure portability, however,
+ you must either provide a function 'yywrap' or, if you don't use
+ it (e.g., your scanner has no '#include'-like feature), simply
+ include a '%noyywrap' statement in the scanner's source.
+
+ This AC_PROG_LEX behaviour is causing some spurious failures of
+ the Automake testsuite in environments which lack a proper library
+ providing 'yywrap' (this happens for example on Fedora-based
+ systems). The proper workaround is to simply provide a fall-back
+ implementation of 'yywrap' in our lexers.
+
+ See also similar commits 'v1.11-546-gca0ba5d' (24-10-2011),
+ 'v1.11-1085-gb5c3968' (24-10-2011) and 'v1.11-871-geb147a1'

+ "lex library").

+
+ depcomp tests: avoid redundant runs for libtool tests
+
+ When running libtool-oriented tests, our 'depcomp.sh' script used
+ to run the same checks thrice: once after having run configure
+ with the '--disable-shared' option, once after having run it with
+ the '--enable-shared' option, and once by allowing configure to
+ automatically select which kind of library (or libraries) to build.
+
+ This was done to offer extra coverage for the less-common depmodes
+ (like "aix" of "hp2") where the name of the compiler-generated
+ depfiles can depend on whether libtool is in use *and* on which
+ kind of libraries libtool is building (static, shared, or both).
+ About this, see commit 'Release-1-10-24-ge89ec38' of 28-03-2007,
+ "* lib/depcomp (aix): Rewrite depmode in the spirit of the tru64
+ one".
+
+ But that extra coverage came at the price of *considerably* slowing
+ down the depcomp libtool-oriented tests, since for each of them the
+ tested source tree was configured and built *twelve* times (rather
+ than "just" four as it is for the non-libtool case).
+
+ So, to strike a balance between coverage and speed, we now run the
+ libtool-oriented tests with the three different configuration modes
+ *only* when it is possible that the depmode that will get selected
+ is one of those which can actually benefit from the extra coverage.
+
+ * tests/depcomp.sh: Adjust to only run the threefold libtool tests
+ when that can truly be potentially useful. Add related explanatory
+ comments.

+ tests: avoid wrong skips in dist-formats.tap
+
+ * tests/dist-formats.tap: The test checking whether the 'compress'

+ occurs; alas, this reasonable assumption doesn't hold in practice,
+ since 'compress' does (and is documented to) exit with status 2 if
+ the output is larger than the input after (attempted) compression!
+ Fix this by using and input that 'compress' can actually reduce in
+ size when compressing.
+ Do some related reformatting of surrounding code since we are at it.

+
+ tests: better way to compare lists in Makefile rules
+
+ With this commit, we introduce a new helper shell script for use
+ in the testsuite, which is meant to allow the test cases to easily
+ check whether two whitespace-separated lists are equal; this ability
+ is particularly useful to check for equality of the contents of make
+ variables that are expected to contain multiple whitespace-separated
+ words, and are defined through line continuations (or are rewritten
+ by automake in this way), or that contain expansion of potentially
+ empty variables.
+
+ Before this change, a test checking that an usage like this one:
+
+ VAR = valA
+ if COND1
+ VAR += val1 # com1
+ endif COND1
+ VAR += valC
+
+ worked as expected, couldn't use rules like:
+
+ ## Doesn't work because $(VAR) expands to multiple words
+ verify:
+ test $(VAR) = "valA val1 valC"
+
+ nor like:
+
+ ## Doesn't work because the final expansion of $(VAR) contains
+ ## repeated contiguous whitespace characters (it actually
+ ## equals "valA val1 valC", not "valA val1 valC"), and this
+ ## is an internal detail which might change and which we don't
+ ## want to explicitly rely on.
+ verify:
+ test "$(VAR)" = "valA val1 valC"
+
+ Instead, we had to rely on cumbersome workaround such as:
+
+ ## This works, but is ugly.
+ verify:
+ test "`echo $(VAR)`" = "valA val1 valC"
+
+ or:
+
+ ## This works, but is even uglier.
+ verify:
+ echo BEG: $(VAR) :END | grep "BEG: valA val1 valC :END"
+
+ Now, with the help of the new 'is' script, we can perform such a
+ check in a clearer and more straightforward way, as in:
+
+ ## Works, and reads clearly.
+ verify:
+ is $(VAR) == valA val1 valC

+
+ tests: improve and rework tests on dependency tracking
+
+ Fixes automake bug#10434. Suggestion by Peter Rosin.
+
+ The 'depcomp.tap' test case worked by trying to unconditionally
+ force the compiler in use by the testsuite to use, one by one, *all*
+ the dependency modes known by the 'depcomp' script, and, for each
+ such forced mode that was compatible enough with said compiler not
+ to cause breakage in the basic compilation rules, checking that it
+ was *also* good enough not to break remake rules in VPATH builds.
+
+ This seemed a good approach when this test was first introduced, as
+ it apparently increased coverage for the less used and less tested
+ dependency-tracking modes. But in the log run it turned out the
+ approach was actually in part too brittle, causing some annoying
+ spurious failures (as with the Tru64 depmode forced on GCC, see
+ automake bug#10434), and partly too forgiving, since, for some of
+ the more corner-case dependency modes, the 'depcomp' script simply
+ reverts to silently disabling dependency tracking when an error is
+ encountered (this happened e.g., with the Tru64 depmode forced on
+ the Sun C compiler 5.9), so that a passing test means nothing, and
+ only gives a false sense of security.
+
+ As Peter Rosin put it, "it's just dead wrong to assume that feeding
+ -M or -xM to the compiler (or whatever other random stuff 'depcomp'
+ might do) and not get an error is the same as dependencies magically
+ appearing".
+
+ So we get rid of this wrong approach, and in the process proceed to
+ a complete overhaul of many of the tests on automatic dependency
+ tracking, extending the offered coverage and rationalizing their
+ organization.
+
+ * tests/depcomp.sh: New helper script, used by several new
+ autogenerated tests.

+
+ dryrun: fix regression with '$(am__make_dryrun)'
+
+ In commit v1.11-683-gda0964e of 05-02-2012, we introduced a new
+ variable '$(am__make_dryrun)' that could be used in recipes to
+ determine whether make is running in dry mode (e.g., as with
+ "make -n"). Unfortunately, the idiom we used fails to take into
+ account the case in which $(MAKEFLAGS) contains one or more variable
+ definitions whose value is a whitespace-separated list; for example,
+ if we invoke make as:
+
+ make check TESTS="n1.test n2.test"
+
+ then the better make implementations out there (at least modern
+ GNU make and BSD make) will export MAKEFLAGS to the following
+ value:
+
+ TESTS=n1.test\ n2.test
+
+ So a shell loop like the one we used in $(am__make_dryrun):
+
+ for flag in $$MAKEFLAGS; do ...
+
+ won't behave as expected: the shell word-splitting rules will break
+ up the entry for TESTS into the two distinct entries "TESTS=n1.test\"
+ and "n2.test", and this second entry will goad our $(am__make_dryrun)
+ code into thinking that make is performing a dry run!
+
+ So now we simply loop over the expanded value of $(MAKEFLAGS).
+ This solves the regression, but alas, is more brittle in case the
+ users passes on the command line a macro value containing unbalanced
+ " or ' quotes, or shell metacharacters like, say, '`' or '('. This
+ should almost never happen though, so we don't worry about it now;
+ we will revisit the issue only when and if we receive bug reports in
+ this area.

+
+ tests: work around bug#7884 in many yacc/lex tests
+
+ Due to automake bug#7884, many test cases on Yacc/Lex support are
+ failing when run with FreeBSD make. Since these failures are all
+ due to the same bug, and that bug is well understood and already
+ explicitly exposed in the dedicated 'yacc-dist-nobuild.test' test,
+ the reported failures are mostly noise, that not only is annoying,
+ but which might end up covering different real bugs or regressions.
+
+ Thus we minimize such spurious failures, by ensuring the commands
+ triggering them (most of them being "make distcheck" invocations)
+ will be skipped when $MAKE suffers of the bug/limitation that
+ triggers automake bug#7884.

+
+ refactor: new variable telling whether make is running in "dry mode"
+
+ We define a new variable '$(am__make_dryrun)', that can be used
+ in recipes to determine whether make is running in "dry mode" (as
+ with "make -n") or not. This is useful in rules that invoke make
+ recursively, and are thus executed also with "make -n" -- either
+ because they are declared as dependencies to '.MAKE' (NetBSD make)
+ or because their recipes contain the "$(MAKE)" string (GNU and
+ Solaris make).

+ tap/perl: handle missing or non-executable scripts better
+
+ This change improves how our Perl-based TAP driver handles
+ non-runnable test scripts (meaning they might be not executable,
+ or not readable, or even not exist). In particular, it makes the
+ driver deterministically display a clear "ERROR" result instead
+ of possibly dying with diagnostic from 'TAP::Parser' internals,
+ and prevents it from displaying spurious "missing TAP plan" errors.
+
+ Moreover, with this change, some testsuite failures present only
+ with newer perl versions (e.g., 5.14) are fixed. See automake
+ bug#10418.
+
+ * tests/tap-bad-prog.tap: When testing the perl implementation of
+ the TAP driver, and when the perl interpreter offers a good-enough
+ 'IPC::Open3::open3' function, expect it not to display spurious
+ "missing TAP plan" diagnostic if the error is actually due to a
+ non-runnable test script.
+ * lib/tap-driver.pl (start): Removed, broken up into ...
+ (setup_io): ... this ...
+ (setup_parser): ... and this, which now tries to catch and report
+ errors in launching the test scripts.
+ (finish): New, used by both 'main' and 'setup_parser'.

+
+ tests: avoid spurious failure of 'transform2.test' on Cygwin
+
+ On newer Cygwin versions (at least 1.7.x), the 'transform2.test'
+ test has been failing spuriously; the gist is the following:
+ some *purposefully* rigged install rules there try something
+ like:
+
+ install bla.exe .../inst/bin/foo.exe
+ install script.sh .../inst/bin/foo
+
+ and the second install command fails (trying to overwrite the
+ '.../inst/bin/foo.exe' file, likely due to overly aggressive
+ appending of '.exe' suffix when copying/renaming Windows
+ executables). Since this is a Cygwin issue rather than an
+ Automake one (and since the use case we are testing is a really
+ corner-case anyway, making it unworthy to attempt to work
+ around it in automake proper), we simply hack the test case
+ to avoid the failure.

+ tests: work around MinGW/MSYS issue in fd redirections
+
+ Some checks on $(AM_TESTS_FD_REDIRECT) were failing on MSYS, likely
+ because system calls like "write(9, ...)" simply doesn't work for
+ MinGW-compiled programs. Similar usages work for the shell scripts
+ though, since /bin/sh is an MSYS program and thus is a lot more
+ POSIX-ish than most MinGW-compiled programs.
+
+ The best fix for this issue is to separate the checks using shell

+ readme: how to run the testsuite with cross-compilers
+
+ * tests/README: Suggest a better way to run the automake testsuite
+ with cross-compilers -- that is, configuring the Automake source
+ tree with proper `--build' and `--host' configure option. And
+ yes, specifying both these options (not only `--host') is indeed
+ required to avoid spurious failures in corner cases.
+ When you call configure with the `--host' option but without the
+ `--build' option, configure tries to auto-detect whether you are
+ cross-compiling or not, by trying to run a generated executable.
+ That test might spuriously "succeed" in some corner cases (e.g.,
+ Cygwin is able to run non-Cygwin apps). In fact, generally, it
+ can be the case that a cross-compilation is not detected as a
+ cross anymore just because someone has installed an emulator; as
+ an example, think of what can happen on a GNU/Linux system that
+ is configured (through the use of the binfmt_misc kernel module)
+ to execute PE executables (compiled for MS-DOS or Windows) through
+ Wine *automatically*. In conclusion, configure needs to be used
+ as recommended in the documentation (i.e., by specifying *both*
+ `--host' and `--build' instead of just one of them) to not have
+ the build fall into any of a number of weird traps.

+ We prefer non-GNU compilers to the GNU ones, to ensure better

+
+ multilib: deprecate, will be moved to contrib
+
+ As of 2012-01-17, according to Google codesarch, almost no active
+ package is using the 'multilib' feature offered by automake.
+
+ The only major exception seems to be GCC... But on a closer look,
+ it become clear that GCC basically carries its own version of
+ multilib support. In fact, Automake syncs its 'config-ml.in' and
+ 'symlink-tree' scripts from GCC; and the GCC repository contains a
+ version of the 'multi.m4' file that is *more* updated than the one
+ in the automake repository (the former having being modified the
+ last time in 2008, the latter only in 2006).
+
+ The 'multilib' feature was anyway hardly documented at all, only
+ being briefly cited in the manual as an "obscure feature", "still
+ experimental", that was only for users "familiar with multilibs"
+ and which "can debug problems they might encounter". We expect
+ such users to be motivated and knowledgeable enough to make the
+ minor adjustments required to start using the contrib version of
+ multilib, if they really need to.
+
+ * NEWS (Future backward incompatibility): Update.
+ * doc/automake.texi: Deprecate multilib support. State that it
+ will be removed from automake core in the next major release.
+ * m4/multi.m4 (AM_ENABLE_MULTILIB): Deprecate. If called, now

+ retaining its former behaviour for the rest).

+
+ cmdline parsing: move into a dedicated perl module
+
+ With this change, we delegate most of the automake and aclocal code
+ for command-line options parsing to a new module "Automake::Getopt".
+ This allows better code sharing between automake and aclocal, and
+ also with Autoconf, which will sync the new module from us. See
+ also autoconf commit 'v2.68-120-gf4be358' (2012-01-17, "getopt: new
+ Autom4te::Getopt module"), and this mailing list discussion:
+ <http://lists.gnu.org/archive/html/autoconf-patches/2012-01/msg00033.html>
+
+ This change might interact with the behaviour described in automake
+ bug#7434; for example, starting from now, "automake -Wfoo --version"
+ will cause automake to emit diagnostic like "unknown warning
+ category 'foo'" before actually printing the version number and
+ exiting. This is not a big deal in practice, and the code sharing
+ and simplifications introduced by this patch is certainly worth it.
+ Still, we should revisited the issue in the future.
+
+ * lib/Automake/Getopt.pm: New module, basically a slightly-edited

+ repository (commit v2.68-120-gf4be358). It defines and exports ...

+ other one ('parallel-tests-dry-run.test') in the master branch.
+
+ Needless to say, their too-much-similar names can be a great source
+ of confusion now. Moreover, the two tests have been written during
+ distinct refactorings, and are meant to exercise different code
+ paths and/or usage scenarios, so that no one of them subsumes the
+ other, and they should be both kept.
+
+ Thus we simply rename both of them to avoid future confusion.

+ maintcheck: consistency of list of test scripts
+
+ This is basically a backport of commit 'v1.11-358-g7b6ab07'
+ and its follow-ups. The possibility of easily checking that
+ the list of test scripts listed in a Makefile equals that of
+ the tests on the filesystem has proved itself so useful that
+ it's worth taking the annoyance of backporting it to maint.

+ 'v1.11-1736-g083a75b') with minor adjustments.
+ (maintainer-check-list-of-tests): New target, check for consistency
+ between the list of tests defined in the including Makefile and the

+ case when we used to have some entries in $(TESTS) that were not
+ real files, but rather "parameters" (sort of) for the corresponding
+ $(LOG_COMPILER). However, that usage had proven to be confusing
+ and brittle, and thus removed (see commit 'v1.11-1308-g375f23d' of

+ (path-check): Remove. The 'pathchk' program running in this check
+ complains about any file with name longer than 14 characters, which
+ is a ridiculously low limit for today standards. Also, we already

+ that limit, and nobody ever complained (not even on MinGW/MSYS nor

+
+ This change fixes automake bug#10470.
+
+ On MSYS (1.0.17) it is not possible to remove a directory that is
+ in use, and this, together with timing issues, could cause spurious
+ failures in the cleanup code of the "distcheck" recipe. In fact,
+ it should be noted that assuming a directory can be removed while
+ it the CWD of a running process is a POSIX violation:
+
+ "If the directory is the root directory or the current working
+ directory of any process, it is unspecified whether the function
+ succeeds, or whether it shall fail and set errno to [EBUSY]."

+ * lib/am/distdir.am (am__remove_distdir): If rm fails, sleep some

+
+ This change fixes automake bug#10444 a.k.a. bug#10448.
+
+ The 'dist-xz' and 'dist-lzip' recipes were erroneously using
+ '$(am__remove_distdir)' instead of '$(am__post_remove_distdir)'
+ to cleanup the '$(distdir)'; so a "make dist" issued in a package
+ using (say) gzip and xz compression would have failed to properly

+ removed by "make dist-xz" upon its completion, instead of being
+ left populated for the following "make dist-gzip".
+
+ The problem with 'dist-xz' was introduced in the merge commit

+ tests: safer declarations of test dependencies
+
+ To declare prerequisites common to all the tests, we now prefer to
+ use the special `check_DATA' and `check_SCRIPTS' variables rather
+ than "lazy" dependency declaration like "$(TEST_LOGS): DEPS ...";
+ this because the latter, allowing run-time overriding of the
+ TEST_LOGS variable, turned out to be subtly incomplete in some
+ situations involving non-trivial inter-test dependencies. For
+ example, if the user issued a:
+
+ make check TESTS=libtool.test
+
+ before the `defs-static' file was created (either explicitly or
+ implicitly), a spurious errors followed, along these lines:
+
+ 1. $(TEST_LOGS) got dynamically defined to `libtool.log';
+
+ 2. make saw that, in the Makefile, `libtool.log' was explicitly
+ declared depending on `libtool-macros.log' and `defs-static';
+
+ 3. somehow, make considered the dependency on `libtool-macros.log'
+ *before* considering the one on `defs-static' (which BTW is
+ perfectly legitimate on make's part);
+
+ 4. to satisfy such a dependency, make set out to execute the
+ test `libtool-macros.test' in order to create the file
+ `libtool-macros.log';
+
+ 5. since `libtool-macros.log' was *not* in $(TEST_LOGS), it
+ didn't appear to depend on the `defs-static' file, so make
+ didn't consider necessary to build `defs-static' before
+ running the `libtool-macros.test' script;
+
+ 6. but that script sources `./defs-static' in order to work;
+ thus the test `libtool-macros.test' failed spuriously.
+
+ * tests/Makefile.am ($(TEST_LOGS)): Remove explicit declaration
+ of dependency on the required files/scripts; instead use ...
+ (check_SCRIPTS, check_DATA): ... these new variables.

+ tests: skip tests on perl TAP driver if TAP::Parser is not available
+
+ We had so far taken for granted that all the perl installations
+ modern enough to correctly run automake also came with a built-in
+ TAP::Parser module; unfortunately, testing on MinGW/MSYS has
+ shown that this is not always true, and that a lot of spurious
+ testsuite failures would take place in such a situation (see
+ automake bug#10440).
+
+ Luckily, the perl implementation of the Automake TAP driver is
+ only meant to be used for prototyping and consistency checks, the
+ "real" Automake TAP driver being the portable one implemented in
+ awk. So we can simply skip the affected tests on systems lacking
+ TAP::Parser.

+ the desired tap driver implementation is the perl one but the
+ TAP::Parser module is unavailable.
+ * tests/tap-bad-prog.tap: Adjust order of calls to `plan_' and

+ * tests/tap-bad-signal.tap: Tweak to avoid the need to source the

+ when the tested TAP driver implementation is not the perl one.
+ On the other hand, when it *is* the perl one, skip the test if

+ * tests/test-driver-cond.test: Skip the part of the test actually
+ running "make check" if the TAP::Parser module is unavailable.

+
+ The `missing' script is meant to allow non-developers to build a

+ * lib/am/check.am (recheck, recheck-html): In order to strip
+ trailing whitespace from the definition of the `$list' variable,
+ we used to invoke sed in a way that could cause it to get passed
+ overly long input lines, causing spurious failures. So rework
+ the logic of the recipe to avoid any sed invocation, relying on
+ simpler shell idioms instead.
+ (check-TESTS): Reorganize the recipe to be more similar to the
+ one of `recheck', for consistency and simplicity.

+
+ dist: obsolete support for lzma (superseded by xz and lzip)
+
+ The lzma utilities are today superseded by the xz utilities; in
+ fact, the official site at <http://tukaani.org/lzma/> reads:
+
+ ``LZMA Utils are legacy data compression software with high
+ compression ratio. LZMA Utils are no longer developed, ...
+ Users of LZMA Utils should move to XZ Utils.''
+
+ and the existing automake manual (as of 1.11.2) already says:
+
+ ``dist-xz
+ Generate an 'xz' tar archive of the distribution. xz archives
+ are frequently smaller than bzip2-compressed archives. The 'xz'
+ format will soon (early 2009) displace the 'lzma' format''
+
+ Also, the `dist-lzma' target still suffers of never-solved bugs,
+ due to the too-high compression ratio its uses by default, which
+ might cause an unacceptable memory consumption when one tries to
+ compress or, worse, decompress the created tarballs; see also:

+
+ Many maintainer checks in the top-level Makefile.am did some

+
+ This failed to properly take into account VPATH builds (where some

+
+ test defs: more granular overriding of the make program
+
+ Before this change, the only way the user could override the make
+ program used in the automake test cases was to override the $MAKE
+ variable in the environment. This had the annoying side effect of
+ requiring that, whenever a non-default make program was to be used
+ in the test cases, that same make program had to be used to drive
+ the execution of the automake testsuite; otherwise, the recursive
+ make invocations could pick up $MAKE from the environment, and use
+ that instead of re-executing with the correct make.
+
+ So, for example, if one wanted to try how Solaris /usr/ccs/bin/make
+ behaved in the automake test cases, he couldn't run the testsuite
+ in parallel mode, because that make lacks support for concurrent
+ execution of recipes; on fast machines, this easily meant a 4x or
+ higher slow-down.
+
+ Once the problem is clear, the solution is pretty simple: allow
+ the use of another variable, besides $MAKE, to override the make
+ program to be used in the test cases.
+
+ See also commit `v1.11-1318-g3ceeef4', that introduced a more
+ general version of this change to the master branch.
+
+ * tests/defs.in: Allow the make implementation to be used by the
+ test cases to be overridden by the `$AM_TESTSUITE_MAKE' variable,
+ in preference to the `$MAKE' variable.

+
+ docs: fix a couple broken anchors
+
+ * doc/automake.texi: In previous commit v1.11-605-g5f71f2b (related
+ to automake bug#8071), we had renamed the chapters about aclocal
+ and automake invocation, and added anchors to the old names as not
+ to break hyperlinks to our on-line manual. Unfortunately, these
+ anchors had been erroneously placed *before* the relevant `@node'
+ commands, instead that just after, so that they ended up pointing
+ to the wrong chapters. Fix this. Since we are at it, tweak the
+ wording of the comments to the anchors to better match that used
+ in the autoconf manual.

+* When documenting a non-trivial idiom or example in the manual, be
+ sure to add a test case for it, and to reference such test case from
+ a proper Texinfo comment.
+
+* Some files in the automake package are not owned by automake; these
+ files are listed in the $(FETCHFILES) variable in Makefile.am. They
+ should never be edited here. Almost all of them can be updated from
+ respective upstreams with "make fetch" (this should be done especially
+ before releases). The only exception is the 'lib/COPYING' (from FSF),
+ which should be updated by hand whenever the GPL gets updated (which
+ shouldn't happen that often anyway :-)
+
+* Changes other than bug fixes must be mentioned in NEWS. Important
+ bug fixes should be mentioned in NEWS, too.
+
+================================================================
+= Naming
+
+* We've adopted the convention that internal AC_SUBSTs should be
+ named with a leading 'am__', and internally generated targets
+ should be named with a leading 'am--'. This convention, although
+ in place from at least February 2001, isn't yet universally used.
+ But all new code should use it.
+
+ We used to use '_am_' as the prefix for an internal AC_SUBST.
+ However, it turns out that NEWS-OS 4.2R complains if a Makefile
+ variable begins with the underscore character. Yay for them.
+ I changed the target naming convention just to be safe.
+
+================================================================
+= Editing '.am' files
+
+* Always use $(...) and not ${...}
+
+* Use ':', not 'true'. Use 'exit 1', not 'false'.
+
+* Use '##' comments liberally. Comment anything even remotely
+ unusual.
+
+* Never use basename or dirname. Instead use sed.
+
+* Do not use 'cd' within back-quotes, use '$(am__cd)' instead.
+ Otherwise the directory name may be printed, depending on CDPATH.
+ More generally, do not ever use plain 'cd' together with a relative
+ directory that does not start with a dot, or you might end up in one
+ computed with CDPATH.
+
+* For install and uninstall rules, if a loop is required, it should be
+ silent. Then the body of the loop itself should print each
+ "important" command it runs. The printed commands should be preceded
+ by a single space.
+
+* Ensure install rules do not create any installation directory where
+ nothing is to be actually installed. See automake bug#11030.
+
+================================================================
+= Editing automake.in and aclocal.in
+
+* Indent using GNU style. For historical reasons, the perl code
+ contains portions indented using Larry Wall's style (perl-mode's
+ default), and other portions using the GNU style (cperl-mode's
+ default). Write new code using GNU style.
+
+* Don't use & for function calls, unless required.
+ The use of & prevents prototypes from being checked.
+ Just as above, don't change massively all the code to strip the
+ &, just convert the old code as you work on it, and write new
+ code without.
+
+================================================================
+= Working with git
+
+* To regenerate dependent files created by aclocal and automake,
+ use the 'bootstrap.sh' script. It uses the code from the source
+ tree, so the resulting files (aclocal.m4 and Makefile.in) should
+ be the same as you would get if you install this version of
+ automake and use it to generate those files. Be sure to have the
+ latest stable version of Autoconf installed and available early
+ in your PATH.
+
+* The Automake git tree currently carries two basic branches: 'master' for
+ the current development, and 'maint' for maintenance and bug fixes. The
+ maint branch should be kept regularly merged into the master branch.
+ It is advisable to merge only after a set of related commits have been
+ applied, to avoid introducing too much noise in the history.
+
+* There may be a number of longer-lived feature branches for new
+ developments. They should be based off of a common ancestor of all
+ active branches to which the feature should or might be merged later.
+ in the future, we might introduce a special branch named 'next' that
+ may serve as common ground for feature merging and testing, should
+ they not yet be ready for master.
+
+* After a major release is done, the master branch is to be merged into
+ the maint branch, and then a "new" master branch created stemming
+ from the resulting commit.
+
+* When fixing a bug (especially a long-standing one), it may be useful
+ to commit the fix to a new temporary branch based off the commit that
+ introduced the bug. Then this "bugfix branch" can be merged into all
+ the active branches descending from the buggy commit. This offers a
+ simple way to fix the bug consistently and effectively.
+
+* For merges from branches other than maint, prefer 'git merge --log' over
+ plain 'git merge', so that a later 'git log' gives an indication of which
+ actual patches were merged even when they don't appear early in the list.
+
+* master and release branches should not be rewound, i.e., should always
+ fast-forward, except maybe for privacy issues. The maint branch should not
+ be rewound except maybe after retiring a release branch or a new stable
+ release. For next, and for feature branches, the announcement for the
+ branch should document rewinding policy.
+
+================================================================
+= Writing a good commit message
+
+* Here is the general format that Automake's commit messages are expected
+ to follow. See the further points below for clarifications and minor
+ corrections.
+
+ topic: brief description (this is the "summary line")
+
+ <reference to relevant bugs, if any>
+
+ Here goes a more detailed explanation of why the commit is needed,
+ and a general overview of what it does, and how. This section is
+ optional, but you are expected to provide it more often than not.
+
+ And if the detailed explanation is quite long or detailed, you can
+ want to break it in more paragraphs.
+
+ Then you can add references to relevant mailing list discussions
+ (if any), with proper links. But don't take this as an excuse for
+ writing incomplete commit messages! The "distilled" conclusions
+ reached in such discussions should have been placed in the
+ paragraphs above.
+
+ Finally, here you can thank people that motivated or helped the
+ change. So, thanks to John Doe for bringing up the issue, and to
+ J. Random Hacker for providing suggestions and testing the patch.
+
+ <detailed list of touched files>
+
+* The <detailed list of touched files> is mandatory but for the most
+ trivial changes, and should follows the GNU guidelines for ChangeLog
+ entries (described explicitly in the GNU Coding Standards); it might
+ be something of this sort:
+
+ * some/file (func1): Improved frobnication.
+ (func2): Adjusted accordingly.
+ * another/file (foo, bar): Likewise.
+ * tests/foo.tap: New test.
+ * tests/Makefile.am (TESTS): Add it.
+
+* If your commit fixes an automake bug registered in the tracker (say
+ numbered 1234), you should put the following line after the summary
+ line:
+
+ This change fixes automake bug#1234.
+
+* If your commit is just related to the given bug report, but does not
+ fix it, you might want to add a line like this instead:
+
+ This change is related to automake bug#1234.
+
+* When referring to older commits, use 'git describe' output as pointer.
+ But also try to identify the given commit by date and/or summary line
+ if possible. Examples:
+
+ Since yesterday's commit, v1.11-2019-g4d2bf42, ...
+
+ ... removed in commit 'v1.11-1674-g02e9072' of 01-01-2012,
+ "dist: ditch support for lzma"...
+
+================================================================
+= Test suite
+
+* Use "make check" and "make maintainer-check" liberally.
+
+* Make sure each test file is executable.
+
+* Export the 'keep_testdirs' environment variable to "yes" to keep
+ test directories for successful tests also.
+
+* Use perl coverage information to ensure your new code is thoroughly
+ tested by your new tests.
+
+* See file 't/README' for more information.
+
+================================================================
+= Release procedure
+
+* The steps outlined here are meant to be followed for alpha and stable
+ releases as well. Where differences are expected, they will be
+ explicitly described.
+
+* Fetch new versions of the files that are maintained by the FSF by
+ running "make fetch". In case any file in the automake repository
+ has been updated, commit and re-run the testsuite.
+
+* Ensure that the copyright notices of the distributed files is up to
+ date. The maintainer-only target "update-copyright" can help with
+ this.
+
+* Update NEWS.
+
+* Update the version number in configure.ac.
+ (The idea is that every other alpha number will be a net release.
+ The repository will always have its own "odd" number so we can easily
+ distinguish net and repo versions.)
+
+* Run this:
+ ./bootstrap.sh && ./configure && make && make check && make distcheck
+
+* Run "make git-tag-release".
+ This will run the maintainer checks, verify that the local git
+ repository and working tree are clean and up-to-date, and create
+ a proper signed git tag for the release (based on the contents
+ of $(VERSION)).
+
+* Run "make git-upload-release".
+ This will first verify that you are releasing from a tagged version
+ and that the local git repository and working tree are clean and
+ up-to-date, and will then run "make dist" to create the tarballs,
+ and invoke the 'gnupload' script sign and upload them to the correct
+ locations. In case you need to sign with a non-default key, you can
+ use "make GNUPLOADFLAGS='--user KEY' git-upload-release".
+
+* Update version number in configure.ac to next alpha number.
+ Re-run ./bootstrap.sh and commit.
+
+* Don't forget to "git push" your changes so they appear in the public
+ git tree.
+
+* For stable releases, update the manuals at www.gnu.org:
+ - Generate manuals:
+ cd doc
+ wget "http://savannah.gnu.org/cgi-bin/viewcvs/~checkout~/texinfo/texinfo/util/gendocs.sh"
+ wget "http://savannah.gnu.org/cgi-bin/viewcvs/~checkout~/texinfo/texinfo/util/gendocs_template"
+ sh ./gendocs.sh --email bug-automake@gnu.org automake "GNU Automake"
+ - copy manuals recursively to web cvs,
+ - commit.
+ - Check for link errors, fix them, recheck until convergence:
+ <http://validator.w3.org/checklink>
+
+* Send the announcement at least to <autotools-announce@gnu.org> and
+ <automake@gnu.org>. If the release is a stable one, the announcement
+ must also go to <info-gnu@gnu.org>; if it is an alpha or beta release,
+ announcement should be sent also to <platform-testers@gnu.org>, to
+ maximize the possibility of early testing on exotic or proprietary
+ systems. Finally, copy the announcement into the NEWS feed at
+ <https://savannah.gnu.org/projects/automake>.

+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
+
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

--- /dev/null
+New in 1.12.1:
+
+* WARNING: Future backward-incompatibilities!
+
+ - Starting from either the next minor version (1.12.2) or the next major
+ version (1.13), Automake will start warning if 'configure.in' is used
+ instead of 'configure.ac' as the Autoconf input. Future versions of
+ Automake will drop support for 'configure.in' altogether.
+
+ - Autoconf 2.65 or later will be required by the next major Automake
+ version (1.13). Until now, Automake has required Autoconf version
+ 2.62 or later.
+
+ - Starting from the next major Automake version (1.13), the rules to
+ build pdf, ps and dvi output from Texinfo input will use the '--tidy'
+ option by default. Since such an option was introduced in Texinfo
+ 4.9, this means that Makefiles generated by future Automake versions
+ will require at least that version of Texinfo.
+
+ - Starting from the next major Automake version (1.13), the parallel
+ testsuite harness (previously only enabled by the 'parallel-tests'
+ option) will become the default one; the older serial testsuite
+ harness will still be available through the use of the 'serial-tests'
+ option.
+
+ - The following long-obsolete m4 macros will be removed in the
+ next major Automake version (1.13):
+
+ AM_PROG_CC_STDC: superseded by AC_PROG_CC since October 2002
+ fp_PROG_CC_STDC: broken alias for AM_PROG_CC_STDC
+ fp_WITH_DMALLOC: old alias for AM_WITH_DMALLOC
+ AM_CONFIG_HEADER: superseded by AC_CONFIG_HEADERS since July 2002
+ ud_PATH_LISPDIR: old alias for AM_PATH_LISPDIR
+ jm_MAINTAINER_MODE: old alias for AM_MAINTAINER_MODE
+ ud_GNU_GETTEXT: old alias for AM_GNU_GETTEXT
+ gm_PROG_LIBTOOL: old alias for AC_PROG_LIBTOOL
+ fp_C_PROTOTYPES: old alias for AM_C_PROTOTYPES (which was part
+ of the now-removed automatic de-ANSI-fication
+ support of Automake)
+
+ - All the "old alias" macros in 'm4/obsolete.m4' will be removed in
+ the next major Automake version (1.13).
+
+ - Support for the two- and three-arguments invocation forms of the
+ AM_INIT_AUTOMAKE macro will be deprecated in the next minor version
+ of Automake (1.12.1) and removed in the next major version (1.13).
+
+ - The '--acdir' option of aclocal is deprecated, and will probably
+ be removed in the next major Automake release (1.13). You should
+ use the options '--automake-acdir' and '--system-acdir' instead
+ (which have been introduced in Automake 1.11.2).
+
+ - The exact order in which the directories in the aclocal macro
+ search path are looked up is probably going to be changed in the
+ next Automake release (1.13).
+
+* New supported languages:
+
+ - Support for Objective C++ has been added; it should work similarly to
+ the support for Objective C.
+
+* Deprecated obsolescent features:
+
+ - Use of the long-deprecated two- and three-arguments invocation forms
+ of the AM_INIT_AUTOMAKE macro now elicits a warning in the 'obsolete'
+ category. Starting from the next major Automake release (1.13), such
+ usages won't be allowed anymore.
+
+ - Support for the "Cygnus-style" trees (enabled by the 'cygnus' option) is
+ now deprecated (its use triggers a warning in the 'obsolete' category).
+ It will be removed in the next major Automake release (1.13).
+
+ - The long-obsolete (since 1.10) automake-provided $(mkdir_p) make
+ variable, @mkdir_p@ configure-time substitution and AM_PROG_MKDIR
+ m4 macro are deprecated, eliciting a warning in the 'obsolete'
+ category. They will be removed in the next major version (1.13).
+
+* Miscellaneous changes:
+
+ - The Automake test cases now require a proper POSIX-conforming shell.
+ Older non-POSIX Bourne shells (like Solaris 10 /bin/sh) won't be
+ accepted anymore. In most cases, the user shouldn't have to specify
+ such POSIX shell explicitly, since it will be looked up at configure
+ time. Still, when this lookup fails, or when the user wants to
+ override its conclusion, the variable 'AM_TEST_RUNNER_SHELL' can be
+ used (pointing to the shell that will be used to run the Automake
+ test cases).
+
+Bugs fixed in 1.12.1:
+
+* Bugs introduced by 1.12:
+
+ - Several weaknesses in Automake's own build system and test suite
+ have been fixed.
+
+* Bugs introduced by 1.11.3:
+
+ - When given non-option arguments, aclocal rejects them, instead of
+ silently ignoring them.
+
+* Long-standing bugs:
+
+ - When the 'color-tests' option is in use, forcing of colored testsuite
+ output through "AM_COLOR_TESTS=always" works even if the terminal is
+ a non-ANSI one, i.e., if the TERM environment variable has a value of
+ "dumb".
+
+ - Several inefficiencies and poor performances in the implementation
+ of the parallel-tests 'check' and 'recheck' targets have been fixed.
+
+ - The post-processing of output "#line" directives done the ylwrap
+ script is more faithful w.r.t. files in a subdirectory; for example,
+ if the processed file is "src/grammar.y", ylwrap will correctly
+ produce directives like:
+ #line 7 "src/grammar.y"
+ rather than like
+ #line 7 "grammar.y"
+ as it did before.
+
+* Bugs with new Perl versions:
+
+ - Aclocal works correctly with perl 5.16.0 (automake bug#11543).
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.12:
+
+* Obsolete features removed:
+
+ - The never documented nor truly used script 'acinstall' has been
+ removed.
+
+ - Support for automatic de-ANSI-fication has been removed.
+
+ - The support for the "obscure" multilib feature has been removed
+ from Automake core (but remains available in the 'contrib/'
+ directory of the Automake distribution).
+
+ - Support for ".log -> .html" conversion and the check-html and
+ recheck-html targets has been removed from Automake core (but
+ remains available in the 'contrib/' directory of the Automake
+ distribution).
+
+ - The deprecated 'lzma' compression format for distribution archives
+ has been removed, in favor of 'xz' and 'lzip'.
+
+ - The obsolete AM_WITH_REGEX macro has been removed.
+
+ - The long-deprecated options '--output-dir', '--Werror' and
+ '--Wno-error' have been removed.
+
+ - The chapter on the history of Automake has been moved out of the
+ reference manual, into a new dedicated Texinfo file.
+
+* New targets:
+
+ - New 'cscope' target to build a cscope database for the source tree.
+
+* Changes to Automake-generated testsuite harnesses:
+
+ - The new automake option 'serial-tests' has been introduced. It can
+ be used to explicitly instruct automake to use the older serial
+ testsuite harness. This is still the default at the moment, but it
+ might change in future versions.
+
+ - The 'recheck' target (provided by the parallel testsuite harness) now
+ depends on the 'all' target. This allows for a better user-experience
+ in test-driven development. See automake bug#11252.
+
+ - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
+ and unexpected or internal error, or a failure to set up the test case
+ scenario) have their outcome reported as an 'ERROR' now. Previous
+ versions of automake reported such an outcome as a 'FAIL' (the only
+ difference with normal failures being that hard errors were counted
+ as failures even when the test originating them was listed in
+ XFAIL_TESTS).
+
+ - The testsuite summary displayed by the parallel-test harness has a
+ completely new format, that always list the numbers of passed, failed,
+ xfailed, xpassed, skipped and errored tests, even when these numbers
+ are zero (but using smart coloring when the color-tests option is in
+ effect).
+
+ - The default testsuite driver offered by the 'parallel-tests' option is
+ now implemented (partly at least) with the help of automake-provided
+ auxiliary scripts (e.g., 'test-driver'), instead of relying entirely
+ on code in the generated Makefile.in.
+ This has two noteworthy implications. The first one is that projects
+ using the 'parallel-tests' option should now either run automake with
+ the '--add-missing' option, or manually copy the 'test-driver' script
+ into their tree. The second, and more important, implication is that
+ now, when the 'parallel-tests' option is in use, TESTS_ENVIRONMENT can
+ not be used anymore to define a test runner, and the command specified
+ in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
+ program or script. For example, this is still a valid usage (albeit
+ a little contorted):
+
+ TESTS_ENVIRONMENT = \
+ if test -n '$(STRICT_TESTS)'; then \
+ maybe_errexit='-e'; \
+ else \
+ maybe_errexit=''; \
+ fi;
+ LOG_COMPILER = $(SHELL) $$maybe_errexit
+
+ while this is not anymore:
+
+ TESTS_ENVIRONMENT = \
+ $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
+
+ neither is this:
+
+ TESTS_ENVIRONMENT = \
+ run_with_perl_or_shell () \
+ { \
+ if grep -q '^#!.*perl' $$1; then
+ $(PERL) $$1; \
+ else \
+ $(SHELL) $$1; \
+ fi; \
+ }
+ LOG_COMPILER = run_with_perl_or_shell
+
+ - The package authors can now use customary testsuite drivers within
+ the framework provided by the 'parallel-tests' testsuite harness.
+ Consistently with the existing syntax, this can be done by defining
+ special makefile variables 'LOG_DRIVER' and '<ext>_LOG_DRIVER'.
+
+ - A new developer-reserved variable 'AM_TESTS_FD_REDIRECT' can be used
+ to redirect/define file descriptors used by the test scripts.
+
+ - The parallel-tests harness generates now, in addition the '.log' files
+ holding the output produced by the test scripts, a new set of '.trs'
+ files, holding "metadata" derived by the execution of the test scripts;
+ among such metadata are the outcomes of the test cases run by a script.
+
+ - Initial and still experimental support for the TAP test protocol is
+ now provided.
+
+* Changes to Yacc and Lex support:
+
+ - C source and header files derived from non-distributed Yacc and/or
+ Lex sources are now removed by a simple "make clean" (while they were
+ previously removed only by "make maintainer-clean").
+
+ - Slightly backward-incompatible change, relevant only for use of Yacc
+ with C++: the extensions of the header files produced by the Yacc
+ rules are now modelled after the extension of the corresponding
+ sources. For example, yacc files named "foo.y++" and "bar.yy" will
+ produce header files named "foo.h++" and "bar.hh" respectively, where
+ they would have previously produced header files named simply "foo.h"
+ and "bar.h". This change offers better compatibility with 'bison -o'.
+
+* Miscellaneous changes:
+
+ - The AM_PROG_VALAC macro now causes configure to exit with status 77,
+ rather than 1, if the vala compiler found is too old.
+
+ - The build system of Automake itself now avoids the use of make
+ recursion as much as possible.
+
+ - Automake now prefers to quote 'like this' or "like this", rather
+ than `like this', in diagnostic message and generated Makefiles,
+ to accommodate the new GNU Coding Standards recommendations.
+
+ - Automake has a new option '--print-libdir' that prints the path of the
+ directory containing the Automake-provided scripts and data files.
+
+ - The 'dist' and 'dist-all' targets now can run compressors in parallel.
+
+ - The rules to create pdf, dvi and ps output from Texinfo files now
+ works better with modern 'texi2dvi' script, by explicitly passing
+ it the '--clean' option to ensure stray auxiliary files are not
+ left to clutter the build directory.
+
+ - Automake can now generate silenced rules for texinfo outputs.
+
+ - Some auxiliary files that are automatically distributed by Automake
+ (e.g., 'install-sh', or the 'depcomp' script for packages compiling
+ C sources) might now be listed in the DIST_COMMON variable in many
+ Makefile.in files, rather than in the top-level one.
+
+ - Messages of types warning or error from 'automake' and 'aclocal'
+ are now prefixed with the respective type, and presence of -Werror
+ is noted.
+
+ - Automake's early configure-time sanity check now tries to avoid
+ sleeping for a second, which slowed down cached configure runs
+ noticeably. In that case, it will check back at the end of the
+ configure script to ensure that at least one second has passed, to
+ avoid time stamp issues with makefile rules rerunning autotools
+ programs.
+
+ - The warnings in the category 'extra-portability' are now enabled by
+ '-Wall'. In previous versions, one has to use '-Wextra-portability'
+ to enable them.
+
+Bugs fixed in 1.12:
+
+ - Various minor bugfixes for recent or long-standing bugs.
+
+* Bugs introduced by 1.11:
+
+ - The AM_COND_IF macro also works if the shell expression for the
+ conditional is no longer valid for the condition.
+
+ - The automake-provided parallel testsuite harness does not fail anymore
+ with BSD make used in parallel mode when there are test scripts in a
+ subdirectory, like in:
+
+ TESTS = sub/foo.test sub/bar.test
+
+* Long-standing bugs:
+
+ - Automake's own build system finally have a real "installcheck" target.
+
+ - Vala-related cleanup rules are now more complete, and work better in
+ a VPATH setup.
+
+ - Files listed with the AC_REQUIRE_AUX_FILE macro in configure.ac are
+ now automatically distributed also if the directory of the auxiliary
+ files coincides with the top-level directory.
+
+ - Automake now detects the presence of the '-d' flag in the various
+ '*YFLAGS' variables even when their definitions involve indirections
+ through other variables, such as in:
+ foo_opts = -d
+ AM_YFLAGS = $(foo_opts)
+
+ - Automake now complains if a '*YFLAGS' variable has any conditional
+ content, not only a conditional definition.
+
+ - Explicit enabling and/or disabling of Automake warning categories
+ through the '-W...' options now always takes precedence over the
+ implicit warning level implied by Automake strictness (foreign, gnu
+ or gnits), regardless of the order in which such strictness and
+ warning flags appear. For example, a setting like:
+ AUTOMAKE_OPTIONS = -Wall --foreign
+ will cause the warnings in category 'portability' to be enabled, even
+ if those warnings are by default disabled in 'foreign' strictness.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bugs fixed in 1.11.5:
+
+* Bugs introduced by 1.11.3:
+
+ - Vala files with '.vapi' extension are now recognized and handled
+ correctly again. See automake bug#11222.
+
+ - Vala support work again for projects that contain some program
+ built from '.vala' (and possibly '.c') sources and some other
+ program built from '.c' sources *only*. See automake bug#11229.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.11.4:
+
+* Miscellaneous changes:
+
+ - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
+ symbol index) modifiers as well as the "s" action, as the symbol index
+ is created unconditionally by Microsoft lib. Also, the "q" (quick)
+ action is now a synonym for "r" (replace). Also, the script has been
+ ignoring the "v" (verbose) modifier already since Automake 1.11.3.
+
+ - When the 'compile' script is used to wrap MSVC, it now accepts an
+ optional space between the -I, -L and -l options and their respective
+ arguments, for better POSIX compliance.
+
+ - There is an initial, experimental support for automatic dependency
+ tracking with tcc (the Tiny C Compiler). Its associated depmode is
+ currently recognized as "icc" (but this and other details are likely
+ to change in future versions).
+
+ - Automatic dependency tracking now works also with the IBM XL C/C++
+ compilers, thanks to the new new depmode 'xlc'.
+
+Bugs fixed in 1.11.4:
+
+* Bugs introduced by 1.11.2:
+
+ - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
+ don't cause spurious failures upon "make install" anymore.
+
+ - The user can now instruct the 'uninstall-info' rule not to update
+ the '${infodir}/dir' file by exporting the environment variable
+ 'AM_UPDATE_INFO_DIR' to the value "no". This is done for consistency
+ with how the 'install-info' rule operates since automake 1.11.2.
+
+* Long-standing bugs:
+
+ - It is now possible for a foo_SOURCES variable to hold Vala sources
+ together with C header files, as well as with sources and headers for
+ other supported languages (e.g., C++). Previously, only mixing C and
+ Vala sources was supported.
+
+ - If "aclocal --install" is used, and the first directory specified with
+ '-I' is non-existent, aclocal will now create it before trying to copy
+ files in it.
+
+ - An empty declaration of a "foo_PRIMARY" don't cause anymore the
+ generated install rules to create an empty $(foodir) directory;
+ for example, if Makefile.am contains something like:
+
+ pkglibexec_SCRIPTS =
+ if FALSE
+ pkglibexec_SCRIPTS += bar.sh
+ endif
+
+ the $(pkglibexec) directory will not be created upon "make install".
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.11.3:
+
+* Miscellaneous changes:
+
+ - Automake's own build system is more silent by default, making use of
+ the 'silent-rules' option.
+
+ - The master copy of the `gnupload' script is now maintained in gnulib,
+ not in automake.
+
+ - The `missing' script doesn't try to wrap calls to `tar' anymore.
+
+ - "make dist" doesn't wrap `tar' invocations with the `missing' script
+ anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
+ shouldn't be using BTW ;-) does not invoke the missing script anymore
+ to wrap tar, but simply invokes the `tar' program itself.
+
+ - "make dist" can now create lzip-compressed tarballs.
+
+ - In the Automake info documentation, the Top node and the nodes about
+ the invocation of the automake and aclocal programs have been renamed;
+ now, calling "info automake" will open the Top node, while calling
+ "info automake-invocation" and "info aclocal-invocation" will access
+ the nodes about the invocation of respectively automake and aclocal.
+
+ - Automake is now distributed as a gzip-compressed and an xz-compressed
+ tarball. Previously, bzip2 was used instead of xz.
+
+ - The last relics of Python 1.5 support have been removed from the
+ AM_PATH_PYTHON macro.
+
+ - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
+ and adds them to the normal list of dependencies, but without
+ overwriting the foo_DEPENDENCIES variable, which is normally computed
+ by automake.
+
+Bugs fixed in 1.11.3:
+
+* Bugs introduced by 1.11.2:
+
+ - Automake now correctly recognizes the prefix/primary combination
+ `pkglibexec_SCRIPTS' as valid.
+
+ - The parallel-tests harness doesn't trip anymore on sed implementations
+ with stricter limits on the length of input lines (problem seen at
+ least on Solaris 8).
+
+* Long-standing bugs:
+
+ - The "deleted header file problem" for *.am files is avoided by stub
+ rules. This allows `make' to trigger a rerun of `automake' also if
+ some previously needed `.am' file has been removed.
+
+ - The `silent-rules' option now generates working makefiles even
+ for the uncommon `make' implementations that do not support the
+ nested-variables extension to POSIX 2008. For such `make'
+ implementations, whether a build is silent is determined at
+ configure time, and cannot be overridden at make time with
+ `make V=0' or `make V=1'.
+
+ - Vala support now works better in VPATH setups.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.11.2:
+
+* Changes to aclocal:
+
+ - The `--acdir' option is deprecated. Now you should use the new options
+ `--automake-acdir' and `--system-acdir' instead.
+
+ - The `ACLOCAL_PATH' environment variable is now interpreted as a
+ colon-separated list of additional directories to search after the
+ automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
+ and before the system acdir (by default ${prefix}/share/aclocal).
+
+* Miscellaneous changes:
+
+ - The Automake support for automatic de-ANSI-fication has been
+ deprecated. It will probably be removed in the next major Automake
+ release (1.12).
+
+ - The `lzma' compression scheme and associated automake option `dist-lzma'
+ is obsoleted by `xz' and `dist-xz' due to upstream changes.
+
+ - You may adjust the compression options used in dist-xz and dist-bzip2.
+ The default is now merely -e for xz, but still -9 for bzip; you may
+ specify a different level via the XZ_OPT and BZIP2 envvars respectively.
+ E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
+
+ - The `compile' script now converts some options for MSVC for a better
+ user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
+
+ - The py-compile script now accepts empty arguments passed to the options
+ `--destdir' and `--basedir', and complains about unrecognized options.
+ Moreover, a non-option argument or a special `--' argument terminates
+ the list of options.
+
+ - A developer that needs to pass specific flags to configure at "make
+ distcheck" time can now, and indeed is advised to, do so by defining
+ the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
+ instead of the old DISTCHECK_CONFIGURE_FLAGS.
+ The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
+ user; still, the old Makefile.am files that used to define it will
+ still continue to work as before.
+
+ - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
+ 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
+ This new macro is required for LIBRARIES and LTLIBRARIES when automake
+ is run with -Wextra-portability and -Werror.
+
+ - When using DejaGnu-based testsuites, the user can extend the `site.exp'
+ file generated by automake-provided rules by defining the special make
+ variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
+
+ - The `install-info' rule can now be instructed not to create/update
+ the `${infodir}/dir' file, by exporting the new environment variable
+ `AM_UPDATE_INFO_DIR' to the value "no".
+
+Bugs fixed in 1.11.2:
+
+* Bugs introduced by 1.11:
+
+ - The parallel-tests driver no longer produces erroneous results with
+ Tru64/OSF 5.1 sh upon unreadable log files.
+
+ - The `parallel-tests' test driver does not report spurious successes
+ when used with concurrent FreeBSD make (e.g., "make check -j3").
+
+ - When the parallel-tests driver is in use, automake now explicitly
+ rejects invalid entries and conditional contents in TEST_EXTENSIONS,
+ instead of issuing confusing and apparently unrelated error messages
+ (e.g., "non-POSIX variable name", "bad characters in variable name",
+ or "redefinition of TEST_EXTENSIONS), or even, in some situations,
+ silently producing broken `Makefile.in' files.
+
+ - The `silent-rules' option now truly silences all compile rules, even
+ when dependency tracking is disabled. Also, when `silent-rules' is
+ not used, `make' output no longer contains spurious backslash-only
+ lines, thus once again matching what Automake did before 1.11.
+
+ - The AM_COND_IF macro also works if the shell expression for the
+ conditional is no longer valid for the condition.
+
+* Long-standing bugs:
+
+ - The order of Yacc and Lex flags is fixed to be consistent with other
+ languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
+ $(LFLAGS), so that the user variables override the developer variables.
+
+ - "make distcheck" now correctly complains also when "make uninstall"
+ leaves one and only one file installed in $(prefix).
+
+ - A "make uninstall" issued before a "make install", or after a mere
+ "make install-data" or a mere "make install-exec" does not spuriously
+ fail anymore.
+
+ - Automake now warns about more primary/directory invalid combinations,
+ such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
+
+ - Rules generated by Automake now try harder to not change any files when
+ `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
+ Yacc source files and the rule to update config.h.
+
+ - Several scripts and the parallel-tests testsuite driver now exit with
+ the right exit status upon receiving a signal.
+
+ - A per-Makefile.am setting of -Werror does not erroneously carry over
+ to the handling of other Makefile.am files.
+
+ - The code for automatic dependency tracking works around a Solaris
+ make bug triggered by sources containing repeated slashes when the
+ `subdir-objects' option was used.
+
+ - The makedepend and hp depmodes now work better with VPATH builds.
+
+ - Java sources specified with check_JAVA are no longer compiled for
+ "make all", but only for "make check".
+
+ - An usage like "java_JAVA = foo.java" will now cause Automake to warn
+ and error out if `javadir' is undefined, instead of silently producing
+ a broken Makefile.in.
+
+ - aclocal and automake now honour the configure-time definitions of
+ AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
+
+ - The `install-info' recipe no longer tries to guess whether the
+ `install-info' program is from Debian or from GNU, and adaptively
+ change its behaviour; this has proven to be frail and easy to
+ regress.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bugs fixed in 1.11.1:
+
+ - Lots of minor bugfixes.
+
+* Bugs introduced by 1.11:
+
+ - The `parallel-tests' test driver works around a GNU make 3.80 bug with
+ trailing white space in the test list (`TESTS = foo $(EMPTY)').
+
+* Long standing bugs:
+
+ - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
+ even if the `--prefix' argument pointed outside of a system directory.
+ AM_PATH_PYTHON has been fixed to ignore the value returned from python's
+ `get_python_lib' function if it points outside the configured prefix,
+ unless the `--prefix' argument was either `/usr' or below `/System'.
+
+ - The testsuite does not try to change the mode of `ltmain.sh' files from
+ a Libtool installation (symlinked to test directories) any more.
+
+ - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
+ tools are preferred in a cross-compile setup.
+
+ - The distribution is tarred up with mode 755 now by the `dist*' targets.
+ This fixes a race condition where untrusted users could modify files
+ in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
+ build directory was world-searchable. This is CVE-2009-4029.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.11:
+
+* Version requirements:
+
+ - Autoconf 2.62 or greater is required.
+
+* Changes to aclocal:
+
+ - The autoconf version check implemented by aclocal in aclocal.m4
+ (and new in Automake 1.10) is degraded to a warning. This helps
+ in the common case where the Autoconf versions used are compatible.
+
+* Changes to automake:
+
+ - The automake program can run multiple threads for creating most
+ Makefile.in files concurrently, if at least Perl 5.7.2 is available
+ with interpreter-based threads enabled. Set the environment variable
+ AUTOMAKE_JOBS to the maximum number of threads to use, in order to
+ enable this experimental feature.
+
+* Changes to Libtool support:
+
+ - Libtool generic flags are now passed to the install and uninstall
+ modes as well.
+
+ - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
+ config.lt is removed correctly now.
+
+* Languages changes:
+
+ - subdir-object mode works now with Fortran (F77, FC, preprocessed
+ Fortran, and Ratfor).
+
+ - For files with extension .f90, .f95, .f03, or .f08, the flag
+ $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
+
+ - Files with extension .sx are also treated as preprocessed assembler.
+
+ - The default source file extension (.c) can be overridden with
+ AM_DEFAULT_SOURCE_EXT now.
+
+ - Python 3.0 is supported now, Python releases prior to 2.0 are no
+ longer supported.
+
+ - AM_PATH_PYTHON honors python's idea about the site directory.
+
+ - There is initial support for the Vala programming language, when using
+ Vala 0.7.0 or later.
+
+* Miscellaneous changes:
+
+ - Automake development is done in a git repository on Savannah now, see
+
+ http://git.sv.gnu.org/gitweb/?p=automake.git
+
+ A read-only CVS mirror is provided at
+
+ cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
+ checkout -d automake HEAD
+
+ - "make dist" can now create xz-compressed tarballs,
+ as well as (deprecated?) lzma-compressed tarballs.
+
+ - `automake --add-missing' will by default install the GPLv3 file as
+ COPYING if it is missing. It will also warn that the license file
+ should be added to source control. Note that Automake will never
+ overwrite an existing COPYING file, even when the `--force-missing'
+ option is used.
+
+ - The manual is now distributed under the terms of the GNU FDL 1.3.
+
+ - Automake ships and installs man pages for automake and aclocal now.
+
+ - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
+
+ - install-sh supports -C, which does not update the installed file
+ (and its time stamps) if the contents did not change.
+
+ - The `gnupload' script has been revamped.
+
+ - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
+
+ - The targets `install' and `uninstall' are more efficient now, in that
+ for example multiple files from one Automake variable such as
+ `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
+ invocation if they do not have to be renamed.
+
+ Both install and uninstall may sometimes enter (`cd' into) the target
+ installation directory now, when no build-local scripts are used.
+
+ Both install and uninstall do not fail anymore but do nothing if an
+ installation directory variable like `bindir' is set to the empty string.
+
+ For built-in rules, `make install' now fails reliably if installation
+ of a file failed. Conversely, `make uninstall' even succeeds when
+ issued multiple times.
+
+ These changes may need some adjustments from users: For example,
+ some `install' programs refuse to install multiple copies of the
+ same file in one invocation, so you may need to remove duplicate
+ entries from file lists.
+
+ Also, within one set of files, say, nobase_data_DATA, the order of
+ installation may be changed, or even unstable among different hosts,
+ due to the use of associative arrays in awk. The increased use of
+ awk matches a similar move in Autoconf to provide for better scaling.
+
+ Further, most undocumented per-rule install command variables such as
+ binSCRIPT_INSTALL have been removed because they are not needed any
+ more. Packages which use them should be using the appropriate one of
+ INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
+ counterpart, depending on the type of files and the need for automatic
+ target directory creation.
+
+ - The "deleted header file problem" for *.m4 files is avoided by
+ stub rules. This allows `make' to trigger a rerun of `aclocal'
+ also if some previously needed macro file has been removed.
+
+ - Rebuild rules now also work for a removed `subdir/Makefile.in' in
+ an otherwise up to date tree.
+
+ - The `color-tests' option causes colored test result output on terminals.
+
+ - The `parallel-tests' option enables a new test driver that allows for
+ parallel test execution, inter-test dependencies, lazy test execution
+ for unit-testing, re-testing only failed tests, and formatted result output
+ as RST (reStructuredText) and HTML. Enabling this option may require some
+ changes to your test suite setup; see the manual for details.
+
+ - The `silent-rules' option enables Linux kernel-style silent build output.
+ This option requires the widely supported but non-POSIX `make' feature
+ of recursive variable expansion, so do not use it if your package needs
+ to build with `make' implementations that do not support it.
+
+ To enable less verbose build output, the developer has to use the Automake
+ option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
+ macro. The user may then set the default verbosity by passing the
+ `--enable-silent-rules' option to `configure'. At `make' run time, this
+ default may be overridden using `make V=0' for less verbose, and `make V=1'
+ for backward-compatible verbose output.
+
+ - New prefix `notrans_' for manpages which should not be transformed
+ by --program-transform.
+
+ - New macro AM_COND_IF for conditional evaluation and conditional
+ config files.
+
+ - For AC_CONFIG_LINKS, if source and destination are equal, do not
+ remove the file in a non-VPATH build. Such setups work with Autoconf
+ 2.62 or newer.
+
+ - AM_MAINTAINER_MODE now allows for an optional argument specifying
+ the default setting.
+
+ - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
+ useful especially for multi-line values.
+
+ - Automake's early configure-time sanity check now diagnoses an
+ unsafe absolute source directory name and makes configure fail.
+
+ - The Automake macros and rules cope better with whitespace in the
+ current directory name, as long as the relative path to `configure'
+ does not contain whitespace. To this end, the values of `$(MISSING)'
+ and `$(install_sh)' may contain suitable quoting, and their expansion
+ might need `eval'uation if used outside of a makefile. These
+ undocumented variables may be used in several documented macros such
+ as $(AUTOCONF) or $(MAKEINFO).
+
+Bugs fixed in 1.11:
+
+* Long-standing bugs:
+
+ - Fix aix dependency tracking for libtool objects.
+
+ - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
+ unnecessary use of the `compile' script.
+
+ - For nobase_*_LTLIBRARIES with nonempty directory components, the
+ correct `-rpath' argument is used now.
+
+ - `config.status --file=Makefile depfiles' now also works with the
+ extra quoting used internally by Autoconf 2.62 and newer
+ (it used to work only without the `--file=' bit).
+
+ - The `missing' script works better with versioned tool names.
+
+ - Semantics for `missing help2man' have been revamped:
+
+ Previously, if `help2man' was not present, `missing help2man' would have
+ the following semantics: if some man page was out of date but present, then
+ a warning would be printed, but the exit status was 0. If the man page was
+ not present at all, then `missing' would create a replacement man page
+ containing an error message, and exit with a status of 2. This does not play
+ well with `make': the next run will see this particular man page as being up
+ to date, and will only error out on the next generated man page, if any;
+ repeat until all pages are done. This was not desirable.
+
+ These are the new semantics: if some man page is not present, and help2man
+ is not either, then `missing' will warn and generate the replacement page
+ containing the error message, but exit successfully. However, `make dist'
+ will ensure that no such bogus man pages are packaged into a tarball.
+
+ - Targets provided by automake behave better with `make -n', in that they
+ take care not to create files.
+
+ - `config.status Makefile... depfiles' works fine again in the presence of
+ disabled dependency tracking.
+
+ - The default no-op recursive rules for these targets also work with BSD make
+ now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
+
+ - `make distcheck' works also when both a directory and some file below it
+ have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
+
+ - Texinfo dvi, ps, pdf, and html output files are not removed upon
+ `make mostlyclean' any more; only the LaTeX by-products are.
+
+ - Renamed objects also work with the `subdir-objects' option and
+ source file languages which Automake does not know itself.
+
+ - `automake' now correctly complains about variable assignments which are
+ preceded by a comment, extend over multiple lines with backslash-escaped
+ newlines, and end in a comment sign. Previous versions would silently
+ and wrongly ignore such assignments completely.
+
+* Bugs introduced by 1.10:
+
+ - Fix output of dummy dependency files in presence of post-processed
+ Makefile.in's again, but also cope with long lines.
+
+ - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
+ that have been declared as programs in the same Makefile.
+ This is for consistency with the analogous change to TESTS in 1.10.
+
+ - Fix order of standard includes to again be `-I. -I$(srcdir)',
+ followed by directories containing config headers.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.10:
+
+* Version requirements:
+
+ - Autoconf 2.60 or greater is required.
+
+ - Perl 5.6 or greater is required.
+
+* Changes to aclocal:
+
+ - aclocal now also supports -Wmumble and -Wno-mumble options.
+
+ - `dirlist' entries (for the aclocal search path) may use shell
+ wildcards such as `*', `?', or `[...]'.
+
+ - aclocal supports an --install option that will cause system-wide
+ third-party macros to be installed in the local directory
+ specified with the first -I flag. This option also uses #serial
+ lines in M4 files to upgrade local macros.
+
+ The new aclocal options --dry-run and --diff help to review changes
+ before they are installed.
+
+ - aclocal now outputs an autoconf version check in aclocal.m4 in
+ projects using automake.
+
+ For a few years, automake and aclocal have been calling autoconf
+ (or its underlying engine autom4te) to accurately retrieve the
+ data they need from configure.ac and its siblings. Doing so can
+ only work if all autotools use the same version of autoconf. For
+ instance a Makefile.in generated by automake for one version of
+ autoconf may stop working if configure is regenerated with another
+ version of autoconf, and vice versa.
+
+ This new version check ensures that the whole build system has
+ been generated using the same autoconf version.
+
+* Support for new Autoconf macros:
+
+ - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
+
+ - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
+ $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
+ in different directories. However, only one instance of such a
+ library objects directory is supported.
+
+* Change to Libtool support:
+
+ - Libtool generic flags (those that go before the --mode=MODE option)
+ can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
+
+* Yacc and Lex changes:
+
+ - The rebuild rules for distributed Yacc and Lex output will avoid
+ overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
+ is not enabled.
+
+ - ylwrap is now always used for lex and yacc source files,
+ regardless of whether there is more than one source per directory.
+
+* Languages changes:
+
+ - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
+ AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
+ tracking, unlike non-preprocessed assembler (*.s).
+
+ - subdir-object mode works now with Assembler. Automake assumes
+ that the compiler understands `-c -o'.
+
+ - Preprocessed assembler (*.S) compilation now also honors
+ $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
+
+ - Improved support for Objective C:
+ - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
+ - A new section of the manual documents the support.
+
+ - New support for Unified Parallel C:
+ - AM_PROG_UPC looks for a UPC compiler.
+ - A new section of the manual documents the support.
+
+ - Per-target flags are now correctly handled in link rules.
+
+ For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
+ for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
+ preferred AM_CFLAGS over maude_CFLAGS while linking, and they
+ used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
+
+ The fix for compiler flags (i.e., using maude_CFLAGS instead of
+ AM_CFLAGS) should not hurt any package since that is how _CFLAGS
+ is expected to work (and actually works during compilation).
+
+ However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
+ "in addition to" breaks backward compatibility with older versions.
+ If your package used both variables, as in
+
+ AM_LDFLAGS = common flags
+ bin_PROGRAMS = a b c
+ a_LDFLAGS = more flags
+ ...
+
+ and assumed *_LDFLAGS would sum up, you should rewrite it as
+
+ AM_LDFLAGS = common flags
+ bin_PROGRAMS = a b c
+ a_LDFLAGS = $(AM_LDFLAGS) more flags
+ ...
+
+ This new behavior of *_LDFLAGS is more coherent with other
+ per-target variables, and the way *_LDFLAGS variables were
+ considered internally.
+
+* New installation targets:
+
+ - New targets mandated by GNU Coding Standards:
+ install-dvi
+ install-html
+ install-ps
+ install-pdf
+ By default they will only install Texinfo manuals.
+ You can customize them with *-local variants:
+ install-dvi-local
+ install-html-local
+ install-ps-local
+ install-pdf-local
+
+ - The undocumented recursive target `uninstall-info' no longer exists.
+ (`uninstall' is in charge of removing all possible documentation
+ flavors, including optional formats such as dvi, ps, or info even
+ when `no-installinfo' is used.)
+
+* Miscellaneous changes:
+
+ - Automake no longer complains if input files for AC_CONFIG_FILES
+ are specified using shell variables.
+
+ - clean, distribution, or rebuild rules are normally disabled for
+ inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
+ AC_CONFIG_LINK specified using shell variables. However, if these
+ variables are used as ${VAR}, and AC_SUBSTed, then Automake will
+ be able to output rules anyway.
+ (See the Automake documentation for AC_CONFIG_FILES.)
+
+ - $(EXEEXT) is automatically appended to filenames of TESTS
+ that have been declared as programs in the same Makefile.
+ This is mostly useful when some check_PROGRAMS are listed in TESTS.
+
+ - `-Wportability' has finally been turned on by default for `gnu' and
+ `gnits' strictness. This means, automake will complain about %-rules
+ or $(GNU Make functions) unless you switch to `foreign' strictness or
+ use `-Wno-portability'.
+
+ - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
+ $(MKDIR_P) instead of $(mkdir_p) to create directories. The
+ $(mkdir_p) variable is still defined (to the same value as
+ $(MKDIR_P)) but should be considered obsolete. If you are using
+ $(mkdir_p) in some of your rules, please plan to update them to
+ $(MKDIR_P) at some point.
+
+ - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
+ They still work in this release, but may be withdrawn in a future one.
+
+ - Inline compilation rules for gcc3-style dependency tracking are
+ more readable.
+
+ - Automake installs a "Hello World!" example package in $(docdir).
+ This example is used throughout the new "Autotools Introduction"
+ chapter of the manual.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.9:
+
+* Makefile.in bloat reduction:
+
+ - Inference rules are used to compile sources in subdirectories when
+ the `subdir-objects' option is used and no per-target flags are
+ used. This should reduce the size of some projects a lot, because
+ Automake used to output an explicit rule for each such object in
+ the past.
+
+ - Automake no longer outputs three rules (.o, .obj, .lo) for each
+ object that must be built with explicit rules. It just outputs
+ the rules required to build the kind of object considered: either
+ the two .o and .obj rules for usual objects, or the .lo rule for
+ libtool objects.
+
+* Change to Libtool support:
+
+ - Libtool tags are used with libtool versions that support them.
+ (I.e., with Libtool 1.5 or greater.)
+
+ - Automake is now able to handle setups where a libtool library is
+ conditionally installed in different directories, as in
+
+ if COND
+ lib_LTLIBRARIES = liba.la
+ else
+ pkglib_LTLIBRARIES = liba.la
+ endif
+ liba_la_SOURCES = ...
+
+* Changes to aclocal:
+
+ - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
+ really evaluated, before it decides to include them in aclocal.m4.
+ This solves nasty problems with conditional redefinitions of
+ Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
+ *.m4 files to be included in any project using these macros.
+ (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
+ most famous instance of this bug.)
+
+ - Do not complain about missing conditionally AC_REQUIREd macros
+ that are not actually used. In 1.8.x aclocal would correctly
+ determine which of these macros were really needed (and include
+ only these in the package); unfortunately it would also require
+ all of them to be present in order to run. This created
+ situations were aclocal would not work on a tarball distributing
+ all the macros it uses. For instance running aclocal on a project
+ containing only the subset of the Gettext macros in use by the
+ project did not work, because gettext conditionally requires other
+ macros.
+
+* Portability improvements:
+
+ - Tar format can be chosen with the new options tar-v7, tar-ustar, and
+ tar-pax. The new option filename-length-max=99 helps diagnosing
+ filenames that are too long for tar-v7. (PR/414)
+
+ - Variables aumented with `+=' are now automatically flattened (i.e.,
+ trailing backslashes removed) and then wrapped around 80 colummns
+ (adding trailing backslashes). In previous versions, a long series
+ of
+ VAR += value1
+ VAR += value2
+ VAR += value3
+ ...
+ would result in a single-line definition of VAR that could possibly
+ exceed the maximum line length of some make implementations.
+
+ Non-augmented variables are still output as they are defined in
+ the Makefile.am.
+
+* Miscellaneous:
+
+ - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
+ Works the same as the old Fortran 77 implementation; just replace
+ F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
+ Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
+
+ - Support for conditional _LISP.
+
+ - Support for conditional -hook and -local rules (PR/428).
+
+ - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
+
+ - Automake will not write any Makefile.ins after the first error it
+ encounters. The previous Makefile.ins (if any) will be left in
+ place. (Warnings will not prevent output, but remember they can
+ be turned into errors with -Werror.)
+
+ - The restriction that SUBDIRS must contain direct children is gone.
+ Do not abuse.
+
+ - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
+ It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bugs fixed in 1.8.5:
+
+* Long-standing bugs:
+
+ - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
+ so that `make distclean' and `make maintainer-clean' can work.
+
+ - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
+
+ - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
+
+ - Polish diagnostic when no input file is found.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bugs fixed in 1.8.4:
+
+* Long-standing bugs:
+
+ - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
+ overridden by the user.
+
+ - Honor PATH_SEPARATOR in various places of the Automake package, for
+ the sake of OS/2.
+
+ - Adjust dependency tracking mode detection to ICC 8.0's new output.
+ (PR/416)
+
+ - Fix install-sh so it can install the `mv' binary... using `mv'.
+
+ - Fix tru64 dependency tracking for libtool objects.
+
+ - Work around Exuberant Ctags when creating a TAGS files in a directory
+ without files to scan but with subdirectories to include.
+
+* Bugs introduced by 1.8:
+
+ - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
+ not defined in the same conditions as the _LDADD that uses it.
+
+ - Do not warn when JAVAROOT is overridden, this is legitimate.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bugs fixed in 1.8.3:
+
+* Long-standing bugs:
+
+ - Quote filenames in installation rules, in case $DESTDIR, $prefix,
+ or any of the other *dir variables contain a space.
+
+ Please note that Automake does not and cannot support spaces in
+ filenames that are involved during the build. This change affects
+ only installation paths, so that `make install' does not bomb out
+ in packages configured with
+ ./configure --prefix '/c/Program Files'
+
+ - Fix the depfiles output so it works with GNU sed (<4.1) even when
+ POSIXLY_CORRECT is set.
+
+ - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
+ since Autoconf 2.54, which defines LIBOBJS itself.
+
+ - Fix a potential (but unlikely) race condition in parallel elisp
+ builds. (Introduced in 1.7.3.)
+
+ - Do not assume that users override _DEPENDENCIES in all conditions
+ where Automake will try to define them.
+
+ - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
+ Solaris 8's `mkdir -p' is not thread-safe and can break parallel
+ builds.
+
+ This fix also affects the $(mkdir_p) variable defined since
+ Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
+ mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
+
+ - Secure temporary directory creation in `make distcheck'. (PR/413)
+
+ - Do not generate two build rules for `parser.h' when the
+ parser appears in two different conditionals.
+
+ - Work around a Solaris 8 /bin/sh bug in the test for dependency
+ checking. Usually ./configure will not pick this shell; so this
+ fix only helps cases where the shell is forced to /bin/sh.
+
+* Bugs introduced by 1.8:
+
+ - In some situations (hand-written `m4_include's), aclocal would
+ call the `File::Spec->rel2abs' method, which was only introduced
+ in Perl 5.6. This new version reestablish support Perl 5.005.
+
+ It is likely that the next major Automake releases will require at
+ least Perl 5.6. Consider upgrading your development environment
+ if you are still using the five-year-old Perl 5.005.
+
+ - Automake would sometimes fail to define rules for targets listed
+ in variables defined in multiple conditions. For instance on
+ if C1
+ bin_PROGRAMS = a
+ else
+ bin_PROGRAMS = b
+ endif
+ it would define only the `a.$(OBJEXT): a.c' rule and omit the
+ `b.$(OBJEXT): b.c' rule.
+
+* New sections in manual:
+
+ - Third-Party Makefiles: how to interface third party Makefiles.
+ - Upgrading: upgrading packages to newer Automake versions.
+ - Multiple Outputs: handling tools that produce many outputs.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bug fixed in 1.8.2:
+
+* A (well known) portability bug slipped in the changes made to
+ install-sh in Automake 1.8.1. The broken install-sh would refuse to
+ install anything on Tru64.
+
+* Fix install rules for conditionally built python files. (This never
+ really worked.)
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Bug fixed in 1.8.1:
+
+* Bugs introduced by 1.8:
+
+ - Fix Config.pm import error with old Perl versions (at least
+ 5.005_03). One symptom is that aclocal could not find its macro
+ directory.
+
+ - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
+ created by `make install' are always world readable, even if the
+ installer happens to have an overly restrictive umask (e.g. 077).
+ This was a mistake and has been reverted. There are at least two
+ reasons why we must not use `-m 0755':
+ - it causes special bits like SGID to be ignored,
+ - it may be too restrictive (some setups expect 775 directories).
+
+ - Fix aclocal to honor definitions located in files which have been
+ m4_included manually. aclocal 1.8 had been updated to check
+ m4_included files for new requirements, but forgot that these
+ m4_included files can also provide new definitions.
+
+ Note that if you have such a setup, we recommend you get rid of
+ it. In the past, there was a reason to m4_include files manually:
+ aclocal used to duplicate entire M4 files into aclocal.m4, even
+ files that were distributed. Some packages were therefore
+ m4_including the distributed file directly, and playing some
+ tricks to ensure aclocal would not copy that file to aclocal.m4,
+ in order to limit the amount of duplication. Since aclocal 1.8.x
+ will precisely output m4_includes for local M4 files, we recommend
+ that you clean up your setup, removing all manual m4_includes and
+ letting aclocal output them.
+
+ - Output detailed menus in the Info version if the Automake manual,
+ so that Emacs can locate the indexes.
+
+ - configure.ac and configure were listed twice in DIST_COMMON (an
+ internal variable where Automake lists configury files to
+ distribute). This was harmless, but unaesthetic.
+
+ - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
+ This was an issue only in the Automake package itself, not in
+ its output.
+
+ - Automake assumed that all AC_CONFIG_LINKS arguments had the form
+ DEST:SRC. This was wrong, as some packages do
+ AC_CONFIG_LINKS($computedlinks). This version no longer abort in
+ that situation.
+
+ - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
+ argument. This caused two kinds of failures:
+ - Rules installing data in a conditionally defined directory
+ failed when that directory was undefined. In this case no
+ argument was supplied.
+ - `make installdirs' failed, because several directories were
+ passed to $(mkdir_p). This was an issue only on platform
+ were $(mkdir_p) is implemented with `install-sh -d'.
+ $(mkdir_p) as been changed to accept 0 or more arguments, as
+ mkinstalldirs did.
+
+* Long-standing bugs:
+
+ - Fix an unexpected diagnostic occurring when users attempt
+ to override some internal variables that Automake appends to.
+
+ - aclocal now scans configure.ac for macro definitions (PR/319).
+
+ - Fix a portability issue with OSF1/Tru64 Make. If a directory
+ distributes files which are outside itself (this usually occurs
+ when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
+ from a parent package), then `make distcheck' fails due to an
+ optimization performed by OSF1/Tru64 Make in its VPATH handling.
+ (tests/subpkg2.test failure)
+
+ - Fix another portability issue with Sun and OSF1/Tru64 Make.
+ In a VPATH-build configuration, `make install' would install
+ nobase_ files to wrong locations.
+
+ - Fix a Perl `uninitialized value' diagnostic occurring when
+ automake complains that a Texinfo file does not have a
+ @setfilename statement.
+
+ - Erase config.status.lineno during `make distclean'. This file
+ can be created by config.status. Automake already knew about
+ configure.lineno, but forgot config.status.lineno.
+
+ - Distribute all files, even those which are built and installed
+ conditionally. This change affects files listed in conditionally
+ defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
+ as well as those listed in conditionally defined dist_*_DATA,
+ dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
+
+ - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
+ doesn't conform to POSIX.
+
+ - Normalize help strings for configure variables and options added
+ by Automake macros.
+
+* Anticipation:
+
+ - Check for python2.4 in AM_PATH_PYTHON.
+
+* Spurious failures in test suite:
+
+ - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
+ tests/ltconv.test: fix failures with CVS Libtool.
+ - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
+ - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
+ fix failures with old Texinfo versions.
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+New in 1.8:
+
+* Meta-News
+
+ - The NEWS file is more verbose.
+
+* Requirements
+
+ - Autoconf 2.58 or greater is required.
+
+* New features
+
+ - Default source file names in the absence of a _SOURCES declaration
+ are made by removing any target extension before appending `.c', so
+ to make the libtool module `foo.la' from `foo.c', you only need to
+ do this:
+
+ lib_LTLIBRARIES = foo.la
+ foo_la_LDFLAGS = -module
+
+ For backward compatibility, foo_la.c will be used instead of
+ foo.c if this file exists or is the explicit target of a rule.
+ However -Wobsolete will warn about this deprecated naming.
+
+ - AR's `cru' flags are now set in a global ARFLAGS variable instead
+ of being hard-coded in each $(AR) invocation, so they can be
+ substituted from configure.ac. This has been requested by people
+ dealing with non-POSIX ar implementations.
+
+ - New warning option: -Woverride. This will warn about any user
+ target or variable definitions which override Automake
+ definitions.
+
+ - Texinfo rules back up and restore info files when makeinfo fails.
+
+ - Texinfo rules now support the `html' target.
+ Running this requires Texinfo 4.0 or greater.
+
+ `html' is a new recursive target, so if your package mixes
+ hand-crafted `Makefile.in's with Automake-generated
+ `Makefile.in's, you should adjust the former to support (or
+ ignore) this target so that `make html' recurses successfully. If
+ you had a custom `html' rule in your `Makefile.am', it's better to
+ rename it as `html-local', otherwise your rule will override
+ Automake's new rule (you can check that by running `automake
+ -Woverride') and that will stop the recursion to subdirectories.
+
+ Last but not least, this `html' rule is declared PHONY, even when
+ overridden. Fortunately, it appears that few packages use a
+ non-PHONY `html' rule.
+
+ - Any file which is m4_included from configure.ac will appear as a
+ configure and Makefile.in dependency, and will be automatically
+ distributed.
+
+ - The rules for rebuilding Makefiles and Makefile.ins will now
+ rebuild all Makefiles and all Makefile.ins at once when one of
+ configure's dependencies has changed. This is considerably faster
+ than previous implementations, where config.status and automake
+ were run separately in each directory (this still happens when you
+ change a Makefile.am locally, without touching configure.ac or
+ friends). Doing this also solves a longstanding issue: these
+ rebuild rules failed to work when adding new directories to the
+ tree, forcing you to run automake manually.
+
+ - For similar reasons, the rules to rebuild configure,
+ config.status, and aclocal.m4 are now defined in all directories.
+ Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
+ CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
+ should better define them in all directories. This is easily done
+ using an AC_SUBST (make sure you prefix these dependencies with
+ $(top_srcdir) since this variable will appear at different
+ levels of the build tree).
+
+ - aclocal will now use `m4_include' instead of copying local m4
+ files into aclocal.m4. (Local m4 files are those you ship with
+ your project, other files will be copied as usual.)
+
+ Because m4_included files are automatically distributed, it means
+ for most projects there is no point in EXTRA_DISTing the list of
+ m4 files which are used. (You can probably get rid of
+ m4/Makefile.am if you had one.)
+
+ - aclocal will avoid touching aclocal.m4 when possible, so that
+ Autom4te's cache isn't needlessly invalidated. This behavior can
+ be switched off with the new `--force' option.
+
+ - aclocal now uses Autoconf's --trace to detect macros which are
+ actually used and will no longer include unused macros simply
+ because they where mentioned. This was often the case for macros
+ called conditionally.
+
+ - New options no-dist and no-dist-gzip.
+
+ - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
+ py-compile, and ylwrap, now all understand --version and --help.
+
+ - Automake will now recognize AC_CONFIG_LINKS so far as removing created
+ links as part of the distclean target and including source files in
+ distributions.
+
+ - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
+ argument. The latter can be used to override the default behavior
+ (which is to abort).
+
+ - Automake will exit with $? = 63 on version mismatch. (So does
+ Autoconf 2.58) missing knows this, and in this case it will
+ emulate the tools as if they were absent. Because older versions
+ of Automake and Autoconf did not use this exit code, this change
+ will only be useful in projects generated with future versions of
+ these tools.
+
+ - When using AC_CONFIG_FILES with multiple input files, Automake
+ generates the first ".in" input file for which a ".am" exists.
+ (Former versions would try to use only the first input file.)
+
+ - lisp_DATA is now allowed. If you are using the empty ELCFILES
+ idiom to disable byte-compilation of lisp_LISP files, it is
+ recommended that you switch to using lisp_DATA. Note that
+ this is not strictly equivalent: lisp_DATA will install elisp
+ files even if emacs is not installed, while *_LISP do not
+ install anything unless emacs is found.
+
+ - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
+ available. This selection is achieved through the Makefile
+ variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
+ `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
+ `$(install_sh) -m 0755 -d'.
+
+* Obsolete features
+
+ - Because `mkdir -p' is available on most platforms, and we can use
+ `install-sh -d' when it is not, the use of the mkinstalldirs
+ script is being phased out. `automake --add-missing' no longer
+ installs it, and if you remove mkinstalldirs from your package,
+ automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
+
+ Gettext 0.12.1 still requires mkinstalldirs. Fortunately
+ gettextize and autopoint will install it when needed. Automake
+ will continue to define the $(mkinstalldirs) and to distribute
+ mkinstalldirs when this script is in the source tree.
+
+ - AM_PROG_CC_STDC is now empty. The content of this macro was
+ merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
+ should adjust it to use $ac_cv_prog_cc_stdc instead. (This
+ renaming should be safe, even if you have to support several,
+ versions of Automake, because AC_PROG_CC defines this variable
+ since Autoconf 2.54.)
+
+ - Some users where using the undocumented ACLOCAL_M4_SOURCES
+ variable to override the aclocal.m4 dependencies computed
+ (inaccurately) by older versions of Automake. Because Automake
+ now tracks configure's m4 dependencies accurately (see m4_include
+ above), the use of ACLOCAL_M4_SOURCES should be considered
+ obsolete and will be flagged as such when running `automake
+ -Wobsolete'.
+
+* Bug fixes
+
+ - Defining programs conditionally using Automake conditionals no
+ longer leads to a combinatorial explosion. The following
+ construct used to be troublesome when used with dozens of
+ conditions.
+
+ bin_PROGRAMS = a
+ if COND1
+ bin_PROGRAMS += a1
+ endif
+ if COND2
+ bin_PROGRAMS += a2
+ endif
+ if COND3
+ bin_PROGRAMS += a3
+ endif
+ ...
+
+ Likewise for _SOURCES, _LDADD, and _LIBADD variables.
+
+ - Due to implementation constraints, previous versions of Automake
+ proscribed multiple conditional definitions of some variables
+ like bin_PROGRAMS:
+
+ if COND1
+ bin_PROGRAMS = a1
+ endif
+ if COND2
+ bin_PROGRAMS = a2
+ endif
+
+ All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
+ This restriction has been lifted, and these variables now
+ support multiple conditional definitions as do other variables.
+
+ - Cleanup the definitions of $(distdir) and $(top_distdir).
+ $(top_distdir) now points to the root of the distribution
+ directory created during `make dist', as it did in Automake 1.4,
+ not to the root of the build tree as it did in intervening
+ versions. Furthermore these two variables are now only defined in
+ the top level Makefile, and passed to sub-directories when running
+ `make dist'.
+
+ - The --no-force option now correctly checks the Makefile.in's
+ dependencies before deciding not to update it.
+
+ - Do not assume that make files are called Makefile in cleaning rules.
+
+ - Update .info files in the source tree, not in the build tree. This
+ is what the GNU Coding Standard recommend. Only Automake 1.7.x
+ used to update these files in the build tree (previous versions did
+ it in the source tree too), and it caused several problems, varying
+ from mere annoyance to portability issues.
+
+ - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
+ when --add-missing and --force-missing are used. For backward
+ compatibility --add-missing will continue to install COPYING (in
+ `gnu' strictness) when none of these three files exist, but this
+ use is deprecated: you should better choose a license yourself and
+ install it once for all in your source tree (and in your code
+ management system).
+
+ - Fix ylwrap so that it does not overwrite header files that haven't
+ changed, as the inline rule already does.
+
+ - User-defined rules override automake-defined rules for the same
+ targets, even when rules do not have commands. This is not new
+ (and was documented), however some of the automake-generated
+ rules have escaped this principle in former Automake versions.
+ Rules for the following targets are affected by this fix:
+
+ clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
+ info, info-am, install-data-am, install-exec-am, install-info,
+ install-info-am, install-man, installcheck-am, maintainer-clean,
+ maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
+ ps, ps-am, uninstall-am, uninstall-info, uninstall-man
+
+ Practically it means that an attempt to supplement the dependencies
+ of some target, as in
+
+ clean: my-clean-rule
+
+ will now *silently override* the automake definition of the
+ rule for this target. Running `automake -Woverride' will diagnose
+ all such overriding definitions.
+
+ It should be noted that almost all these targets support a *-local
+ variant that is meant to supplement the automake-defined rule
+ (See node `Extending' in the manual). The above rule should
+ be rewritten as
+
+ clean-local: my-clean-rule
+
+ These *-local targets have been documented since at least
+ Automake 1.2, so you should not fear the change if you have
+ to support multiple automake versions.
+
+* Miscellaneous
+
+ - The Automake manual is now distributed under the terms of the GNU FDL.
+
+ - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
+
+ - core dumps are no longer removed by the cleaning rules. There are
+ at least three reasons for this:
+ 1. These files should not be created by any build step,
+ so their removal do not fit any of the cleaning rules.
+ Actually, they may be precious to the developer.
+ 2. If such file is created during a build, then it's clearly a
+ bug Automake should not hide. Not removing the file will
+ cause `make distcheck' to complain about its presence.
+ 3. Operating systems have different naming conventions for
+ core dump files. A core file on one system might be a
+ completely legitimate data file on another system.
+
+ - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
+ defined by Automake. This means that any definition in the
+ environment will be used, unless overridden in the Makefile.am or
+ on the command line. The old behavior, where these variables were
+ defined empty in each Makefile, can be obtained by AC_SUBSTing or
+ AC_ARG_VARing each variable from configure.ac.
+
+ - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
+ documented. (The is not a new feature, these variables have
+ been there since at least Automake 1.4.)

+
+Bugs fixed in 1.7.9:
+* Fix install-strip to work with nobase_ binaries.
+* Fix renaming of #line directives in ylwrap.
+* Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
+
+Bugs fixed in 1.7.8:
+* Remove spurious blank lines in cleaning rules introduced in 1.7.7.
+* Fix detection of Debian's install-info, broken since version 1.5.
+ (Debian bug #213524).
+* Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
+ This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
+
+Bugs fixed in 1.7.7:
+* The implementation of automake's --no-force option is unreliable,
+ so this option is ignored in this version. A real fix will appear in
+ Automake 1.8. (Debian Bug #206299)
+* AM_PATH_PYTHON: really check the whole list of interpreters if no
+ argument is given. (PR/399)
+* Do not warn about leading `_' in variable names, even with -Wportability.
+* Support user redefinitions of TEXINFO_TEX.
+* depcomp: support AIX Compiler version 6.
+* Fix missing rebuilds during `make dist' with BSD make.
+ (Could produce tarballs containing out-of-date files.)
+* Resurrect multilib support.
+* Noteworthy manual updates:
+ - Extending aclocal: how to write m4 macros that won't trigger warnings
+ with Automake 1.8.
+ - A Shared Library: Rewrite and split into subsections.
+
+Bugs fixed in 1.7.6:
+* Fix depcomp's icc mode for ICC 7.1.
+* Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
+* Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
+* Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
+* Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
+* Remove Latin-1 characters from elisp-comp.
+* Update the manual's @dircategory to match the Free Software Directory.
+
+Bugs fixed in 1.7.5:
+* Update install-sh's license to remove an advertising clause.
+ (Debian bug #191717)
+* Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
+ that caused invalid Makefile.ins to be generated.
+* Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
+* New FAQ entry: renamed objects.
+
+Bugs fixed in 1.7.4:
+* Tweak the TAGS rule to support Exuberant Ctags (in addition to
+ the Emacs implementation)
+* Fix output of aclocal.m4 dependencies in subdirectories.
+* Use `mv -f' instead of `mv' in fastdep rules.
+* Upgrade mdate-sh to work on OS/2.
+* Don't byte-compile elisp files when ELCFILES is set empty.
+ (this documented feature was broken by 1.7.3)
+* Diagnose trailing backslashes on last line of Makefile.am.
+* Diagnose whitespace following trailing backslashes.
+* Multiple tests are now correctly supported in DEJATOOL. (PR/388)
+* Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
+ Makefiles. (PR/389)
+* `make install' will build `BUILT_SOURCES' first.
+* Minor documentation fixes.
+
+Bugs fixed in 1.7.3:
+* Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
+* Query distutils for `pythondir' and `pythonexecdir', instead of
+ using an hardcoded path. This should allow builds on 64-bit
+ distributions that usually use lib64/ instead of lib/.
+* AM_PATH_PYTHON will also search for python2.3.
+* elisp files are now built all at once instead of one by one. Besides
+ incurring a speed-up, this is required to support interdependent elisp files.
+* Support for DJGPP:
+ - `make distcheck' will now work in `_inst/' and `_build' instead
+ of `=inst/' and `=build/'
+ - use `_dirstamp' when the file-system doesn't support `.dirstamp'
+ - install/uninstall `*.i[0-9][0-9]'-style info files
+ - more changes that affect only the Automake package (not its output)
+* Fix some incompatibilities with upcoming perl-5.10.
+* Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
+ PACKAGE and VERSION.
+* depcomp fixes:
+ - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
+ is troublesome with gcc and Solaris compilers. (PR/385)
+ - makedepend mode: work with Libtool. (PR/385 too)
+ - support for ICC.
+* better support for unusual gettext setups, such as multiple po/ directories
+ (PR/381):
+ - Flag missing po/ and intl/ directories as warnings, not errors.
+ - Disable these warnings if po/ does not exist.
+* Noteworthy manual updates:
+ - New FAQ chapter.
+ - Document how AC_CONFIG_AUX_DIR interacts with missing files.
+ (Debian Bug #39542)
+ - Document `AM_YFLAGS = -d'. (PR/382)
+
+Bugs fixed in 1.7.2:
+* Fix installation and uninstallation of Info files built in subdirectories.
+* Do not run `./configure --with-included-gettext' during `make distcheck'
+ if AM_GNU_GETTEXT([external]) is used.
+* Correctly uninstall renamed man pages.
+* Do not strip escaped newline in variables defined in one condition
+ and augmented in another condition.
+* Fix ansi2knr rules for LIBOBJS sources.
+* Clean all known Texinfo index files, not only those which appear to
+ be used, because we cannot know which indexes are used in included files.
+ (PR/375, Debian Bug #168671)
+* Honor only the first @setfilename seen in a Texinfo file.
+* Treat "required file X not found" diagnostics as errors (exit status 1).
+* Don't complain that a required file is not found when it is a Makefile
+ target. (PR/357)
+* Don't use single suffix inference rules when building `.info'-less
+ Info files, for the sake of Solaris make.
+* The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
+* Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
+* Warn about multiple inference rules when -Wportability is used. (PR/372)
+* Fix building of deansified files from subdirectories. (PR/370)
+* Add missing `fi' in the .c->.obj rules.
+* Improve install-sh to work even when names contain spaces or certain
+ (but not all) shell metachars.
+* Fix the following spurious failures in the test suite:
+ depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
+* Noteworthy manual updates:
+ - Augment the section about BUILT_SOURCES.
+ - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
+
+Bugs fixed in 1.7.1:
+* Honor `ansi2knr' for files built in subdirectories, or using per-targets
+ flags.
+* Aclocal should now recognize macro names containing parentheses, e.g.
+ AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
+* Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
+ (Debian Bug#153697)
+* Install Python files even if they were built. (PR/369)
+* Have stamp-vti dependent upon configure instead of configure.ac, as the
+ version might not be defined in the latter. (PR/358)
+* Reorder arguments passed to a couple of commands, so things works
+ when POSIXLY_CORRECT=1.
+* Fix a regex that can cause Perl to segfault on large input.
+ (Debian Bug#162583)
+* Fix distribution of packages that have some sources defined conditionally,
+ as in the `Conditional compilation using Automake conditionals' example
+ of the manual.
+* Fix spurious test suite failures on IRIX.

+ defined conditionally for the "right" conditions.
+* Fix cleaning of the /tmp subdirectory used by `make distcheck', in case

+
+New in 1.7:
+* Autoconf 2.54 is required.
+* `aclocal' and `automake' will no longer warn about obsolete
+ configure macros. This is done by `autoconf -Wobsolete'.
+* AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
+ AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
+ supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
+ and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
+ `configure.ac' for you.
+* Support for per-program and per-library `_CPPFLAGS'.
+* New `ctags' target (builds CTAGS files).
+* Support for -Wmumble and -Wno-mumble, where mumble is a warning category
+ (see `automake --help' or the manual for a list of them).
+* Honor the WARNINGS environment variable.
+* Omit the call to depcomp when using gcc3: call the compiler directly.
+* A new option, std-options, tests that programs support --help and --version
+ when `make installcheck' is run. This is enabled by --gnits.
+* Texinfo rules now support the `ps' and `pdf' targets.
+* Info files are now created in the build directory, not the source directory.
+* info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
+ or greater).
+* `make distcheck' will enforce DESTDIR support by attempting
+ a DESTDIR install.
+* `+=' can be used in conditionals, even if the augmented variable
+ was defined for another condition.
+* Makefile fragments (inserted with `include') are always distributed.
+* Use Autoconf's --trace interface to inspect configure.ac and get
+ a more accurate view of it.
+* Add support for extending aclocal's default macro search path
+ using a `dirlist' file within the aclocal directory.
+* automake --output-dir is deprecated.
+* The part of the distcheck target that checks whether uninstall actually
+ removes all installed files has been moved in a separate target,
+ distuninstallcheck, so it can be overridden easily.
+* Many bug fixes.
+
+New in 1.6.3:
+* Support for AM_INIT_GETTEXT([external])
+* Bug fixes, including:
+ - Fix Automake's own `make install' so it works even if `ln' doesn't.
+ - nobase_ programs and scripts honor --program-transform correctly.
+ - Erase configure.lineno during `make distclean'.
+ - Erase YACC and LEX outputs during `make maintainer-clean'.
+
+New in 1.6.2:
+* Many bug fixes, including:
+ - Requiring the current version works.

+ - Fix output of dummy dependency files in presence of post-processed
+ Makefile.in's.
+ - Don't compute dependencies in background to avoid races with libtool.
+ - Fix handling of _OBJECTS variables for targets sharing source variables.
+ - Check dependency mode for Java when AM_PROG_GCJ is used.
+
+New in 1.6.1:
+* automake --output-dir is deprecated
+* Many bug fixes, including:
+ - Don't choke on AM_LDFLAGS definitions.
+ - Clean libtool objects from subdirectories.
+ - Allow configure variables with reserved suffix and unknown prefix
+ (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
+ - Fix the definition of AUTOMAKE and ACLOCAL in configure.
+
+New in 1.6:
+* Autoconf 2.52 is required.
+* automake no longer run libtoolize.
+ This is the job of autoreconf (from GNU Autoconf).
+* `dist' generates all the archive flavors, as did `dist-all'.
+* `dist-gzip' generates the Gzip tar file only.
+* Combining Automake Makefile conditionals no longer lead to a combinatorial
+ explosion. Makefile.in's keep a reasonable size.
+* AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
+ are no longer shipped, since Autoconf 2.52 provides them (both as AM_
+ and AC_).
+* `#line' of Lex and Yacc files are properly set.
+* EXTRA_DIST can contain generated directories.
+* Support for dot-less extensions in suffix rules.
+* The part of the distcheck target that checks whether distclean actually
+ cleans all built files has been moved in a separate target, distcleancheck,
+ so it can be overridden easily.
+* `make distcheck' will pass additional options defined in
+ $(DISTCHECK_CONFIGURE_FLAGS) to configure.
+* Fixed CDPATH portability problems, in particular for MacOS X.
+* Fixed handling of nobase_ targets.
+* Fixed support of implicit rules leading to .lo objects.
+* Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
+* Added uninstall-hook target
+* `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
+ You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
+ (Note that "pkgname" is not "tarname", see the manual for details.)
+ It is also possible to pass a list of global Automake options as
+ first argument to this new form of AM_INIT_AUTOMAKE.
+* Compiler-based assembler is now called `CCAS'; people expected `AS'
+ to be a real assembler.
+* AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
+ AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
+* aclocal and automake are also installed with the version number
+ appended, and some of the install directory names have changed.
+ This lets you have multiple versions installed simultaneously.
+* Support for parsers and lexers in subdirectories.
+
+New in 1.5:
+* Support for `configure.ac'.
+* Support for `else COND', `endif COND' and negated conditions `!COND'.
+* `make dist-all' is much faster.
+* Allows '@' AC_SUBSTs in macro names.
+* Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
+* User-side dependency tracking. Developers no longer need GNU make

+* Can now put `.' in SUBDIRS to control build order
+* `include' command and `+=' support for macro assignment
+* Dependency tracking no long susceptible to deleted header file problem

+* Bug fixes
+
+New in 1.3:
+* Bug fixes
+* Better Cygwin32 support
+* Support for suffix rules with _SOURCES variables
+* New options `readme-alpha' and `check-news'; Gnits mode sets these

+This is Automake, a Makefile generator. It aims to be portable and
+to conform to the GNU Coding Standards for Makefile variables and
+targets.
+
+See the INSTALL file for detailed information about how to configure
+and install Automake.
+
+Automake is a Perl script. The input files are called Makefile.am.
+The output files are called Makefile.in; they are intended for use
+with Autoconf. Automake requires certain things to be done in your
+configure.ac.
+
+Automake comes with extensive documentation; please refer to it for
+more details about its purpose, features, and usage patterns.
+
+This package also includes the "aclocal" program, whose purpose is
+to generate an 'aclocal.m4' based on the contents of 'configure.ac'.
+It is useful as an extensible, maintainable mechanism for augmenting
+autoconf. It is intended that other package authors will write m4
+macros which can be automatically used by aclocal. The documentation
+for aclocal is currently found in the Automake manual.
+
+Automake has a test suite. Use "make check" to run it. For more
+information, see the file t/README.
+
+Automake has a page on the web. See:
+
+ http://www.gnu.org/software/automake/
+
+Automake also has three mailing lists:
+
+ * automake@gnu.org
+ For general discussions of Automake and its interactions with other
+ configuration/portability tools like Autoconf or Libtool.
+
+ * bug-automake@gnu.org
+ Where to send bug reports and feature requests.
+
+ * automake-patches@gnu.org
+ Where to send patches, and discuss the automake development process
+ and the design of new features.
+
+To obtain more information about these list, or to subscribe to them,
+refer to <http://www.gnu.org/software/automake/#mailinglists>
+
+New releases are announced to autotools-announce@gnu.org. If you want to
+be informed, subscribe to that list by following the instructions at
+<http://lists.gnu.org/mailman/listinfo/autotools-announce>.
+
+For any copyright year range specified as YYYY-ZZZZ in this package,
+that the range specifies every single year in that closed interval.

+ # Until Automake 1.6.3, .info files were built in the

+ # files.
+ #
+ # * Non-distributed .texi files is important in some packages
+ # where .texi files are built at make time, probably using
+ # other binaries built in the package itself, maybe using
+ # tools or information found on the build host. Because
+ # these files are not distributed they are always rebuilt
+ # at make time; they should therefore not lie in the source
+ # directory. One plan was to support this using
+ # nodist_info_TEXINFOS or something similar. (Doing this
+ # requires some sanity checks. For instance Automake should
+ # not allow:
+ # dist_info_TEXINFOS = foo.texi
+ # nodist_foo_TEXINFOS = included.texi
+ # because a distributed file should never depend on a
+ # non-distributed file.)
+ #
+ # * If .texi files are not distributed, then .info files should
+ # not be distributed either. There are also cases where one
+ # wants to distribute .texi files, but does not want to
+ # distribute the .info files. For instance the Texinfo package
+ # distributes the tool used to build these files; it would
+ # be a waste of space to distribute them. It's not clear
+ # which syntax we should use to indicate that .info files should
+ # not be distributed. Akim Demaille suggested that eventually
+ # we switch to a new syntax:
+ # | Maybe we should take some inspiration from what's already
+ # | done in the rest of Automake. Maybe there is too much
+ # | syntactic sugar here, and you want
+ # | nodist_INFO = bar.info
+ # | dist_bar_info_SOURCES = bar.texi
+ # | bar_texi_DEPENDENCIES = foo.texi
+ # | with a bit of magic to have bar.info represent the whole
+ # | bar*info set. That's a lot more verbose that the current
+ # | situation, but it is # not new, hence the user has less
+ # | to learn.
+ # |
+ # | But there is still too much room for meaningless specs:
+ # | nodist_INFO = bar.info
+ # | dist_bar_info_SOURCES = bar.texi
+ # | dist_PS = bar.ps something-written-by-hand.ps
+ # | nodist_bar_ps_SOURCES = bar.texi
+ # | bar_texi_DEPENDENCIES = foo.texi
+ # | here bar.texi is dist_ in line 2, and nodist_ in 4.
+ #
+ # Back to the point, it should be clear that in order to support
+ # non-distributed .info files, we need to build them in the
+ # build tree, not in the source tree (non-distributed .texi
+ # files are less of a problem, because we do not output build
+ # rules for them). In Automake 1.7 .info build rules have been
+ # largely cleaned up so that .info files get always build in the
+ # build tree, even when distributed. The idea was that
+ # (1) if during a VPATH build the .info file was found to be
+ # absent or out-of-date (in the source tree or in the
+ # build tree), Make would rebuild it in the build tree.
+ # If an up-to-date source-tree of the .info file existed,
+ # make would not rebuild it in the build tree.
+ # (2) having two copies of .info files, one in the source tree
+ # and one (newer) in the build tree is not a problem
+ # because 'make dist' always pick files in the build tree
+ # first.
+ # However it turned out the be a bad idea for several reasons:
+ # * Tru64, OpenBSD, and FreeBSD (not NetBSD) Make do not behave
+ # like GNU Make on point (1) above. These implementations
+ # of Make would always rebuild .info files in the build
+ # tree, even if such files were up to date in the source
+ # tree. Consequently, it was impossible to perform a VPATH
+ # build of a package containing Texinfo files using these
+ # Make implementations.
+ # (Refer to the Autoconf Manual, section "Limitation of
+ # Make", paragraph "VPATH", item "target lookup", for
+ # an account of the differences between these
+ # implementations.)
+ # * The GNU Coding Standards require these files to be built
+ # in the source-tree (when they are distributed, that is).
+ # * Keeping a fresher copy of distributed files in the
+ # build tree can be annoying during development because
+ # - if the files is kept under CVS, you really want it
+ # to be updated in the source tree
+ # - it is confusing that 'make distclean' does not erase
+ # all files in the build tree.
+ #
+ # Consequently, starting with Automake 1.8, .info files are
+ # built in the source tree again. Because we still plan to
+ # support non-distributed .info files at some point, we
+ # have a single variable ($INSRC) that controls whether
+ # the current .info file must be built in the source tree
+ # or in the build tree. Actually this variable is switched
+ # off for .info files that appear to be cleaned; this is
+ # for backward compatibility with package such as Texinfo,
+ # which do things like
+ # info_TEXINFOS = texinfo.txi info-stnd.texi info.texi

+\`configure' configures GNU Automake 1.12.1 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+#
+# We require POSIX and XSI features (e.g., '$(...)' for command
+# substitutions, '$((...))' for shell arithmetic, and support for
+# '${var#...}' and '${var%...}' parameter expansions).
+#
+# We require that the shell can correctly trap EXIT when 'set -e' is in
+# effect (OSF1/Tru64 sh failed to do so, see commit v1.10b-52-g9fe8259).
+#
+# We also prefer shells that, when 'set -x' is in effect, do not also
+# redirect traces upon stderr redirections. For example,
+# $ set -x; echo x 2>file
+# would emit "+ echo x" into file with older zsh versions. Similarly,
+# $ set -x; P=1 true 2>file
+# would emit "P=1" into file with /usr/xpg4/bin/sh from Solaris 10 and
+# /bin/sh from SunOS 5.11 and OpenBSD 4.7.
+#
+# Finally, we look for weird bugs and portability problems mentioned in
+# the Autoconf manual, and reject shells that suffers from them. (TODO)
+#
+# Use '$am_score' to indicate the degree of acceptability of the shell.
+# A score of "10" means that the shell is good enough for our needs;
+# a score of "9" means that the shell has some minor bugs or limitation,
+# but is still (barely) acceptable for our uses. Any other score means
+# that the shell is broken or unfit.

+inclusion into the Automake core.
+
+There are several reasons for which a feature can be kept in contrib:
+
+ 1. The long-term usefulness of the feature is debatable and uncertain;
+ on-field and real-word testing are necessary to prove or disprove
+ its usefulness, before the feature can be committed into the Automake
+ core (as doing so too early would later force us to continue the
+ support for backward-compatibility, even if the features proves
+ flawed or fails to attract widespread use).
+
+ 2. The APIs or overall design of the feature are still unstable, and
+ need on-field testing to iron warts and usability bugs, or uncover
+ potential flaws.
+
+ 3. The feature was an historical one, mostly obsoleted but still used
+ "here and there" in the wild; so we want to to deprecate it and
+ remove it from the Automake core, but cannot remove it altogether,
+ for the sake of those still-existing usage. So it gets moved in
+ contrib.

+#
+# Subdirectories wishing to use multilib should put the following lines
+# in the "post-target" section of configure.in.

+# Things are complicated because 6 separate cases must be handled:
+# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
+#
+# srcdir=. is special. It must handle make programs that don't handle VPATH.
+# To implement this, a symlink tree is built for each library and for each
+# multilib subdir.
+#
+# The build tree is laid out as
+#
+# ./
+# newlib
+# m68020/
+# newlib
+# m68881/
+# newlib
+#
+# The nice feature about this arrangement is that inter-library references
+# in the build tree work without having to care where you are. Note that
+# inter-library references also work in the source tree because symlink trees
+# are built when srcdir=.
+#
+# Unfortunately, trying to access the libraries in the build tree requires
+# the user to manually choose which library to use as GCC won't be able to
+# find the right one. This is viewed as the lesser of two evils.
+#

+# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
+# Set by top level Makefile.
+# ${with_multisrctop} = how many levels of multilibs there are in the source
+# tree. It exists to handle the case of configuring in the source tree:
+# ${srcdir} is not constant.
+# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
+#
+# Makefile variables:
+# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
+# (FIXME: note that this is different than ${with_multisrctop}. Check out.).
+# MULTIBUILDTOP = number of multilib levels in build tree
+# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
+# (only defined in each library's main Makefile).
+# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
+# (only defined in each multilib subdir).
+

+**********
+
+1994-09-19 First CVS commit.
+ If we can trust the CVS repository, David J. MacKenzie (djm)
+ started working on Automake (or AutoMake, as it was spelt then)
+ this Monday.
+
+ The first version of the `automake' script looks as follows.
+
+ #!/bin/sh
+
+ status=0
+
+ for makefile
+ do
+ if test ! -f ${makefile}.am; then
+ echo "automake: ${makefile}.am: No such honkin' file"
+ status=1
+ continue
+ fi
+
+ exec 4> ${makefile}.in
+
+ done
+
+ From this you can already see that Automake will be about reading
+ `*.am' file and producing `*.in' files. You cannot see anything
+ else, but if you also know that David is the one who created
+ Autoconf two years before you can guess the rest.
+
+ Several commits follow, and by the end of the day Automake is
+ reported to work for GNU fileutils and GNU m4.
+
+ The modus operandi is the one that is still used today: variable
+ assignments in `Makefile.am' files trigger injections of precanned
+ `Makefile' fragments into the generated `Makefile.in'. The use of
+ `Makefile' fragments was inspired by the 4.4BSD `make' and include
+ files, however Automake aims to be portable and to conform to the
+ GNU standards for `Makefile' variables and targets.
+
+ At this point, the most recent release of Autoconf is version 1.11,
+ and David is preparing to release Autoconf 2.0 in late October.
+ As a matter of fact, he will barely touch Automake after September.
+
+1994-11-05 David MacKenzie's last commit.
+ At this point Automake is a 200 line portable shell script, plus
+ 332 lines of `Makefile' fragments. In the `README', David states
+ his ambivalence between "portable shell" and "more appropriate
+ language":
+
+ I wrote it keeping in mind the possibility of it becoming an
+ Autoconf macro, so it would run at configure-time. That
+ would slow configuration down a bit, but allow users to
+ modify the Makefile.am without needing to fetch the AutoMake
+ package. And, the Makefile.in files wouldn't need to be
+ distributed. But all of AutoMake would. So I might
+ reimplement AutoMake in Perl, m4, or some other more
+ appropriate language.
+
+ Automake is described as "an experimental Makefile generator".
+ There is no documentation. Adventurous users are referred to the
+ examples and patches needed to use Automake with GNU m4 1.3,
+ fileutils 3.9, time 1.6, and development versions of find and
+ indent.
+
+ These examples seem to have been lost. However at the time of
+ writing (10 years later in September, 2004) the FSF still
+ distributes a package that uses this version of Automake: check
+ out GNU termutils 2.0.
+
+1995-11-12 Tom Tromey's first commit.
+ After one year of inactivity, Tom Tromey takes over the package.
+ Tom was working on GNU cpio back then, and doing this just for fun,
+ having trouble finding a project to contribute to. So while
+ hacking he wanted to bring the `Makefile.in' up to GNU standards.
+ This was hard, and one day he saw Automake on
+ `ftp://alpha.gnu.org/', grabbed it and tried it out.
+
+ Tom didn't talk to djm about it until later, just to make sure he
+ didn't mind if he made a release. He did a bunch of early
+ releases to the Gnits folks.
+
+ Gnits was (and still is) totally informal, just a few GNU friends
+ who Franc,ois Pinard knew, who were all interested in making a
+ common infrastructure for GNU projects, and shared a similar
+ outlook on how to do it. So they were able to make some progress.
+ It came along with Autoconf and extensions thereof, and then
+ Automake from David and Tom (who were both gnitsians). One of
+ their ideas was to write a document paralleling the GNU standards,
+ that was more strict in some ways and more detailed. They never
+ finished the GNITS standards, but the ideas mostly made their way
+ into Automake.
+
+1995-11-23 Automake 0.20
+ Besides introducing automatic dependency tracking (*note
+ Dependency Tracking Evolution::), this version also supplies a
+ 9-page manual.
+
+ At this time `aclocal' and `AM_INIT_AUTOMAKE' did not exist, so
+ many things had to be done by hand. For instance, here is what a
+ configure.in (this is the former name of the `configure.ac' we use
+ today) must contain in order to use Automake 0.20:
+
+ PACKAGE=cpio
+ VERSION=2.3.911
+ AC_DEFINE_UNQUOTED(PACKAGE, "$PACKAGE")
+ AC_DEFINE_UNQUOTED(VERSION, "$VERSION")
+ AC_SUBST(PACKAGE)
+ AC_SUBST(VERSION)
+ AC_ARG_PROGRAM
+ AC_PROG_INSTALL
+
+ (Today all of the above is achieved by `AC_INIT' and
+ `AM_INIT_AUTOMAKE'.)
+
+ Here is how programs are specified in `Makefile.am':
+
+ PROGRAMS = hello
+ hello_SOURCES = hello.c
+
+ This looks pretty much like what we do today, except the
+ `PROGRAMS' variable has no directory prefix specifying where
+ `hello' should be installed: all programs are installed in
+ `$(bindir)'. `LIBPROGRAMS' can be used to specify programs that
+ must be built but not installed (it is called `noinst_PROGRAMS'
+ nowadays).
+
+ Programs can be built conditionally using `AC_SUBST'itutions:
+
+ PROGRAMS = @progs@
+ AM_PROGRAMS = foo bar baz
+
+ (`AM_PROGRAMS' has since then been renamed to `EXTRA_PROGRAMS'.)
+
+ Similarly scripts, static libraries, and data can be built and
+ installed using the `LIBRARIES', `SCRIPTS', and `DATA' variables.
+ However `LIBRARIES' were treated a bit specially in that Automake
+ did automatically supply the `lib' and `.a' prefixes. Therefore
+ to build `libcpio.a', one had to write
+
+ LIBRARIES = cpio
+ cpio_SOURCES = ...
+
+ Extra files to distribute must be listed in `DIST_OTHER' (the
+ ancestor of `EXTRA_DIST'). Also extra directories that are to be
+ distributed should appear in `DIST_SUBDIRS', but the manual
+ describes this as a temporary ugly hack (today extra directories
+ should also be listed in `EXTRA_DIST', and `DIST_SUBDIRS' is used
+ for another purpose, *note Conditional Subdirectories:
+ (automake)Conditional Subdirectories.).
+
+1995-11-26 Automake 0.21
+ In less time than it takes to cook a frozen pizza, Tom rewrites
+ Automake using Perl. At this time Perl 5 is only one year old, and
+ Perl 4.036 is in use at many sites. Supporting several Perl
+ versions has been a source of problems through the whole history
+ of Automake.
+
+ If you never used Perl 4, imagine Perl 5 without objects, without
+ `my' variables (only dynamically scoped `local' variables),
+ without function prototypes, with function calls that needs to be
+ prefixed with `&', etc. Traces of this old style can still be
+ found in today's `automake'.
+
+1995-11-28 Automake 0.22
+1995-11-29 Automake 0.23
+ Bug fixes.
+
+1995-12-08 Automake 0.24
+1995-12-10 Automake 0.25
+ Releases are raining. 0.24 introduces the uniform naming scheme we
+ use today, i.e., `bin_PROGRAMS' instead of `PROGRAMS',
+ `noinst_LIBRARIES' instead of `LIBLIBRARIES', etc. (However
+ `EXTRA_PROGRAMS' does not exist yet, `AM_PROGRAMS' is still in
+ use; and `TEXINFOS' and `MANS' still have no directory prefixes.)
+ Adding support for prefixes like that was one of the major ideas
+ in `automake'; it has lasted pretty well.
+
+ AutoMake is renamed to Automake (Tom seems to recall it was
+ Franc,ois Pinard's doing).
+
+ 0.25 fixes a Perl 4 portability bug.
+
+1995-12-18 Jim Meyering starts using Automake in GNU Textutils.
+
+1995-12-31 Franc,ois Pinard starts using Automake in GNU tar.
+
+1996-01-03 Automake 0.26
+1996-01-03 Automake 0.27
+ Of the many changes and suggestions sent by Franc,ois Pinard and
+ included in 0.26, perhaps the most important is the advice that to
+ ease customization a user rule or variable definition should always
+ override an Automake rule or definition.
+
+ Gordon Matzigkeit and Jim Meyering are two other early contributors
+ that have been sending fixes.
+
+ 0.27 fixes yet another Perl 4 portability bug.
+
+1996-01-13 Automake 0.28
+ Automake starts scanning `configure.in' for `LIBOBJS' support.
+ This is an important step because until this version Automake only
+ knew about the `Makefile.am's it processed. `configure.in' was
+ Autoconf's world and the link between Autoconf and Automake had to
+ be done by the `Makefile.am' author. For instance, if `config.h'
+ was generated by `configure', it was the package maintainer's
+ responsibility to define the `CONFIG_HEADER' variable in each
+ `Makefile.am'.
+
+ Succeeding releases will rely more and more on scanning
+ `configure.in' to better automate the Autoconf integration.
+
+ 0.28 also introduces the `AUTOMAKE_OPTIONS' variable and the
+ `--gnu' and `--gnits' options, the latter being stricter.
+
+1996-02-07 Automake 0.29
+ Thanks to `configure.in' scanning, `CONFIG_HEADER' is gone, and
+ rebuild rules for `configure'-generated file are automatically
+ output.
+
+ `TEXINFOS' and `MANS' converted to the uniform naming scheme.
+
+1996-02-24 Automake 0.30
+ The test suite is born. It contains 9 tests. From now on test
+ cases will be added pretty regularly (*note Releases::), and this
+ proved to be really helpful later on.
+
+ `EXTRA_PROGRAMS' finally replaces `AM_PROGRAMS'.
+
+ All the third-party Autoconf macros, written mostly by Franc,ois
+ Pinard (and later Jim Meyering), are distributed in Automake's
+ hand-written `aclocal.m4' file. Package maintainers are expected
+ to extract the necessary macros from this file. (In previous
+ versions you had to copy and paste them from the manual...)
+
+1996-03-11 Automake 0.31
+ The test suite in 0.30 was run via a long `check-local' rule. Upon
+ Ulrich Drepper's suggestion, 0.31 makes it an Automake rule output
+ whenever the `TESTS' variable is defined.
+
+ `DIST_OTHER' is renamed to `EXTRA_DIST', and the `check_' prefix
+ is introduced. The syntax is now the same as today.
+
+1996-03-15 Gordon Matzigkeit starts writing libtool.
+
+1996-04-27 Automake 0.32
+ `-hook' targets are introduced; an idea from Dieter Baron.
+
+ `*.info' files, which were output in the build directory are now
+ built in the source directory, because they are distributed. It
+ seems these files like to move back and forth as that will happen
+ again in future versions.
+
+1996-05-18 Automake 0.33
+ Gord Matzigkeit's main two contributions:
+
+ * very preliminary libtool support
+
+ * the distcheck rule
+
+ Although they were very basic at this point, these are probably
+ among the top features for Automake today.
+
+ Jim Meyering also provides the infamous `jm_MAINTAINER_MODE', since
+ then renamed to `AM_MAINTAINER_MODE' and abandoned by its author
+ (*note maintainer-mode: (automake)maintainer-mode.).
+
+1996-05-28 Automake 1.0
+ After only six months of heavy development, the `automake' script
+ is 3134 lines long, plus 973 lines of `Makefile' fragments. The
+ package has 30 pages of documentation, and 38 test cases.
+ `aclocal.m4' contains 4 macros.
+
+ From now on and until version 1.4, new releases will occur at a
+ rate of about one a year. 1.1 did not exist, actually 1.1b to
+ 1.1p have been the name of beta releases for 1.2. This is the
+ first time Automake uses suffix letters to designate beta
+ releases, a habit that lasts.
+
+1996-10-10 Kevin Dalley packages Automake 1.0 for Debian GNU/Linux.
+
+1996-11-26 David J. MacKenzie releases Autoconf 2.12.
+ Between June and October, the Autoconf development is almost
+ stalled. Roland McGrath has been working at the beginning of the
+ year. David comes back in November to release 2.12, but he won't
+ touch Autoconf anymore after this year, and Autoconf then really
+ stagnates. The desolate Autoconf `ChangeLog' for 1997 lists only
+ 7 commits.
+
+1997-02-28 <automake@gnu.ai.mit.edu> list alive
+ The mailing list is announced as follows:
+ I've created the "automake" mailing list. It is
+ "automake@gnu.ai.mit.edu". Administrivia, as always, to
+ automake-request@gnu.ai.mit.edu.
+
+ The charter of this list is discussion of automake, autoconf, and
+ other configuration/portability tools (e.g., libtool). It is expected
+ that discussion will range from pleas for help all the way up to
+ patches.
+
+ This list is archived on the FSF machines. Offhand I don't know if
+ you can get the archive without an account there.
+
+ This list is open to anybody who wants to join. Tell all your
+ friends!
+ -- Tom Tromey
+
+ Before that people were discussing Automake privately, on the Gnits
+ mailing list (which is not public either), and less frequently on
+ `gnu.misc.discuss'.
+
+ `gnu.ai.mit.edu' is now `gnu.org', in case you never noticed. The
+ archives of the early years of the `automake@gnu.org' list have
+ been lost, so today it is almost impossible to find traces of
+ discussions that occurred before 1999. This has been annoying
+ more than once, as such discussions can be useful to understand
+ the rationale behind a piece of uncommented code that was
+ introduced back then.
+
+1997-06-22 Automake 1.2
+ Automake developments continues, and more and more new Autoconf
+ macros are required. Distributing them in `aclocal.m4' and
+ requiring people to browse this file to extract the relevant
+ macros becomes uncomfortable. Ideally, some of them should be
+ contributed to Autoconf so that they can be used directly, however
+ Autoconf is currently inactive. Automake 1.2 consequently
+ introduces `aclocal' (`aclocal' was actually started on
+ 1996-07-28), a tool that automatically constructs an `aclocal.m4'
+ file from a repository of third-party macros. Because Autoconf has
+ stalled, Automake also becomes a kind of repository for such
+ third-party macros, even macros completely unrelated to Automake
+ (for instance macros that fix broken Autoconf macros).
+
+ The 1.2 release contains 20 macros, including the
+ `AM_INIT_AUTOMAKE' macro that simplifies the creation of
+ `configure.in'.
+
+ Libtool is fully supported using `*_LTLIBRARIES'.
+
+ The missing script is introduced by Franc,ois Pinard; it is meant
+ to be a better solution than `AM_MAINTAINER_MODE' (*note
+ maintainer-mode: (automake)maintainer-mode.).
+
+ Conditionals support was implemented by Ian Lance Taylor. At the
+ time, Tom and Ian were working on an internal project at Cygnus.
+ They were using ILU, which is pretty similar to CORBA. They
+ wanted to integrate ILU into their build, which was all
+ `configure'-based, and Ian thought that adding conditionals to
+ `automake' was simpler than doing all the work in `configure'
+ (which was the standard at the time). So this was actually funded
+ by Cygnus.
+
+ This very useful but tricky feature will take a lot of time to
+ stabilize. (At the time this text is written, there are still
+ primaries that have not been updated to support conditional
+ definitions in Automake 1.9.)
+
+ The `automake' script has almost doubled: 6089 lines of Perl, plus
+ 1294 lines of `Makefile' fragments.
+
+1997-07-08 Gordon Matzigkeit releases Libtool 1.0.
+
+1998-04-05 Automake 1.3
+ This is a small advance compared to 1.2. It adds support for
+ assembly, and preliminary support for Java.
+
+ Perl 5.004_04 is out, but fixes to support Perl 4 are still
+ regularly submitted whenever Automake breaks it.
+
+1998-09-06 `sourceware.cygnus.com' is on-line.
+ Sourceware was setup by Jason Molenda to host open source projects.
+
+1998-09-19 Automake CVS repository moved to `sourceware.cygnus.com'
+1998-10-26 `sourceware.cygnus.com' announces it hosts Automake:
+ Automake is now hosted on `sourceware.cygnus.com'. It has a
+ publicly accessible CVS repository. This CVS repository is a copy
+ of the one Tom was using on his machine, which in turn is based on
+ a copy of the CVS repository of David MacKenzie. This is why we
+ still have to full source history. (Automake was on Sourceware
+ until 2007-10-29, when it moved to a git repository on
+ `savannah.gnu.org', but the Sourceware host had been renamed to
+ `sources.redhat.com'.)
+
+ The oldest file in the administrative directory of the CVS
+ repository that was created on Sourceware is dated 1998-09-19,
+ while the announcement that `automake' and `autoconf' had joined
+ `sourceware' was made on 1998-10-26. They were among the first
+ projects to be hosted there.
+
+ The heedful reader will have noticed Automake was exactly 4 years
+ old on 1998-09-19.
+
+1999-01-05 Ben Elliston releases Autoconf 2.13.
+
+1999-01-14 Automake 1.4
+ This release adds support for Fortran 77 and for the `include'
+ statement. Also, `+=' assignments are introduced, but it is still
+ quite easy to fool Automake when mixing this with conditionals.
+
+ These two releases, Automake 1.4 and Autoconf 2.13 make a duo that
+ will be used together for years.
+
+ `automake' is 7228 lines, plus 1591 lines of Makefile fragment, 20
+ macros (some 1.3 macros were finally contributed back to
+ Autoconf), 197 test cases, and 51 pages of documentation.
+
+1999-03-27 The `user-dep-branch' is created on the CVS repository.
+ This implements a new dependency tracking schemed that should be
+ able to handle automatic dependency tracking using any compiler
+ (not just gcc) and any make (not just GNU `make'). In addition,
+ the new scheme should be more reliable than the old one, as
+ dependencies are generated on the end user's machine. Alexandre
+ Oliva creates depcomp for this purpose.
+
+ *Note Dependency Tracking Evolution::, for more details about the
+ evolution of automatic dependency tracking in Automake.
+
+1999-11-21 The `user-dep-branch' is merged into the main trunk.
+ This was a huge problem since we also had patches going in on the
+ trunk. The merge took a long time and was very painful.
+
+2000-05-10
+ Since September 1999 and until 2003, Akim Demaille will be
+ zealously revamping Autoconf.
+
+ I think the next release should be called "3.0".
+ Let's face it: you've basically rewritten autoconf.
+ Every weekend there are 30 new patches.
+ I don't see how we could call this "2.15" with a straight
+ face.
+ - Tom Tromey on <autoconf@gnu.org>
+
+ Actually Akim works like a submarine: he will pile up patches
+ while he works off-line during the weekend, and flush them in
+ batch when he resurfaces on Monday.
+
+2001-01-24
+ On this Wednesday, Autoconf 2.49c, the last beta before Autoconf
+ 2.50 is out, and Akim has to find something to do during his
+ week-end :)
+
+2001-01-28
+ Akim sends a batch of 14 patches to <automake@gnu.org>.
+
+ Aiieeee! I was dreading the day that the Demaillator turned
+ his sights on automake... and now it has arrived! - Tom Tromey
+
+ It's only the beginning: in two months he will send 192 patches.
+ Then he would slow down so Tom can catch up and review all this.
+ Initially Tom actually read all these patches, then he probably
+ trustingly answered OK to most of them, and finally gave up and
+ let Akim apply whatever he wanted. There was no way to keep up
+ with that patch rate.
+
+ Anyway the patch below won't apply since it predates Akim's
+ sourcequake; I have yet to figure where the relevant passage
+ has been moved :) - Alexandre Duret-Lutz
+
+ All these patches were sent to and discussed on
+ <automake@gnu.org>, so subscribed users were literally drowning in
+ technical mails. Eventually, the <automake-patches@gnu.org>
+ mailing list was created in May.
+
+ Year after year, Automake had drifted away from its initial design:
+ construct `Makefile.in' by assembling various `Makefile'
+ fragments. In 1.4, lots of `Makefile' rules are being emitted at
+ various places in the `automake' script itself; this does not help
+ ensuring a consistent treatment of these rules (for instance
+ making sure that user-defined rules override Automake's own rules).
+ One of Akim's goal was moving all these hard-coded rules to
+ separate `Makefile' fragments, so the logic could be centralized
+ in a `Makefile' fragment processor.
+
+ Another significant contribution of Akim is the interface with the
+ "trace" feature of Autoconf. The way to scan `configure.in' at
+ this time was to read the file and grep the various macro of
+ interest to Automake. Doing so could break in many unexpected
+ ways; `automake' could miss some definition (for instance
+ `AC_SUBST([$1], [$2])' where the arguments are known only when M4
+ is run), or conversely it could detect some macro that was not
+ expanded (because it is called conditionally). In the CVS version
+ of Autoconf, Akim had implemented the `--trace' option, which
+ provides accurate information about where macros are actually
+ called and with what arguments. Akim will equip Automake with a
+ second `configure.in' scanner that uses this `--trace' interface.
+ Since it was not sensible to drop the Autoconf 2.13 compatibility
+ yet, this experimental scanner was only used when an environment
+ variable was set, the traditional grep-scanner being still the
+ default.
+
+2001-04-25 Gary V. Vaughan releases Libtool 1.4
+ It has been more than two years since Automake 1.4, CVS Automake
+ has suffered lot's of heavy changes and still is not ready for
+ release. Libtool 1.4 had to be distributed with a patch against
+ Automake 1.4.
+
+2001-05-08 Automake 1.4-p1
+2001-05-24 Automake 1.4-p2
+ Gary V. Vaughan, the principal Libtool maintainer, makes a "patch
+ release" of Automake:
+
+ The main purpose of this release is to have a stable automake
+ which is compatible with the latest stable libtool.
+
+ The release also contains obvious fixes for bugs in Automake 1.4,
+ some of which were reported almost monthly.
+
+2001-05-21 Akim Demaille releases Autoconf 2.50
+
+2001-06-07 Automake 1.4-p3
+2001-06-10 Automake 1.4-p4
+2001-07-15 Automake 1.4-p5
+ Gary continues his patch-release series. These also add support
+ for some new Autoconf 2.50 idioms. Essentially, Autoconf now
+ advocates `configure.ac' over `configure.in', and it introduces a
+ new syntax for `AC_OUTPUT'ing files.
+
+2001-08-23 Automake 1.5
+ A major and long-awaited release, that comes more than two years
+ after 1.4. It brings many changes, among which:
+ * The new dependency tracking scheme that uses `depcomp'.
+ Aside from the improvement on the dependency tracking itself
+ (*note Dependency Tracking Evolution::), this also
+ streamlines the use of `automake'-generated `Makefile.in's as
+ the `Makefile.in's used during development are now the same
+ as those used in distributions. Before that the
+ `Makefile.in's generated for maintainers required GNU `make'
+ and GCC, they were different from the portable `Makefile'
+ generated for distribution; this was causing some confusion.
+
+ * Support for per-target compilation flags.
+
+ * Support for reference to files in subdirectories in most
+ `Makefile.am' variables.
+
+ * Introduction of the `dist_', `nodist_', and `nobase_'
+ prefixes.
+
+ * Perl 4 support is finally dropped.
+
+ 1.5 did break several packages that worked with 1.4. Enough so
+ that Linux distributions could not easily install the new Automake
+ version without breaking many of the packages for which they had
+ to run `automake'.
+
+ Some of these breakages were effectively bugs that would
+ eventually be fixed in the next release. However, a lot of damage
+ was caused by some changes made deliberately to render Automake
+ stricter on some setup we did consider bogus. For instance, `make
+ distcheck' was improved to check that `make uninstall' did remove
+ all the files `make install' installed, that `make distclean' did
+ not omit some file, and that a VPATH build would work even if the
+ source directory was read-only. Similarly, Automake now rejects
+ multiple definitions of the same variable (because that would mix
+ very badly with conditionals), and `+=' assignments with no
+ previous definition. Because these changes all occurred suddenly
+ after 1.4 had been established for more than two years, it hurt
+ users.
+
+ To make matter worse, meanwhile Autoconf (now at version 2.52) was
+ facing similar troubles, for similar reasons.
+
+2002-03-05 Automake 1.6
+ This release introduced versioned installation (*note API
+ Versioning: (automake)API Versioning.). This was mainly pushed by
+ Havoc Pennington, taking the GNOME source tree as motive: due to
+ incompatibilities between the autotools it's impossible for the
+ GNOME packages to switch to Autoconf 2.53 and Automake 1.5 all at
+ once, so they are currently stuck with Autoconf 2.13 and Automake
+ 1.4.
+
+ The idea was to call this version `automake-1.6', call all its
+ bug-fix versions identically, and switch to `automake-1.7' for the
+ next release that adds new features or changes some rules. This
+ scheme implies maintaining a bug-fix branch in addition to the
+ development trunk, which means more work from the maintainer, but
+ providing regular bug-fix releases proved to be really worthwhile.
+
+ Like 1.5, 1.6 also introduced a bunch of incompatibilities,
+ intentional or not. Perhaps the more annoying was the dependence
+ on the newly released Autoconf 2.53. Autoconf seemed to have
+ stabilized enough since its explosive 2.50 release and included
+ changes required to fix some bugs in Automake. In order to
+ upgrade to Automake 1.6, people now had to upgrade Autoconf too;
+ for some packages it was no picnic.
+
+ While versioned installation helped people to upgrade, it also
+ unfortunately allowed people not to upgrade. At the time of
+ writing, some Linux distributions are shipping packages for
+ Automake 1.4, 1.5, 1.6, 1.7, 1.8, and 1.9. Most of these still
+ install 1.4 by default. Some distribution also call 1.4 the
+ "stable" version, and present "1.9" as the development version;
+ this does not really makes sense since 1.9 is way more solid than
+ 1.4. All this does not help the newcomer.
+
+2002-04-11 Automake 1.6.1
+ 1.6, and the upcoming 1.4-p6 release were the last release by Tom.
+ This one and those following will be handled by Alexandre
+ Duret-Lutz. Tom is still around, and will be there until about
+ 1.7, but his interest into Automake is drifting away towards
+ projects like `gcj'.
+
+ Alexandre has been using Automake since 2000, and started to
+ contribute mostly on Akim's incitement (Akim and Alexandre have
+ been working in the same room from 1999 to 2002). In 2001 and
+ 2002 he had a lot of free time to enjoy hacking Automake.
+
+2002-06-14 Automake 1.6.2
+
+2002-07-28 Automake 1.6.3
+2002-07-28 Automake 1.4-p6
+ Two releases on the same day. 1.6.3 is a bug-fix release.
+
+ Tom Tromey backported the versioned installation mechanism on the
+ 1.4 branch, so that Automake 1.6.x and Automake 1.4-p6 could be
+ installed side by side. Another request from the GNOME folks.
+
+2002-09-25 Automake 1.7
+ This release switches to the new `configure.ac' scanner Akim was
+ experimenting in 1.5.
+
+2002-10-16 Automake 1.7.1
+2002-12-06 Automake 1.7.2
+2003-02-20 Automake 1.7.3
+2003-04-23 Automake 1.7.4
+2003-05-18 Automake 1.7.5
+2003-07-10 Automake 1.7.6
+2003-09-07 Automake 1.7.7
+2003-10-07 Automake 1.7.8
+ Many bug-fix releases. 1.7 lasted because the development version
+ (upcoming 1.8) was suffering some major internal revamping.
+
+2003-10-26 Automake on screen
+ Episode 49, `Repercussions', in the third season of the `Alias' TV
+ show is first aired.
+
+ Marshall, one of the characters, is working on a computer virus
+ that he has to modify before it gets into the wrong hands or
+ something like that. The screenshots you see do not show any
+ program code, they show a `Makefile.in' generated by automake...
+
+2003-11-09 Automake 1.7.9
+
+2003-12-10 Automake 1.8
+ The most striking update is probably that of `aclocal'.
+
+ `aclocal' now uses `m4_include' in the produced `aclocal.m4' when
+ the included macros are already distributed with the package (an
+ idiom used in many packages), which reduces code duplication.
+ Many people liked that, but in fact this change was really
+ introduced to fix a bug in rebuild rules: `Makefile.in' must be
+ rebuilt whenever a dependency of `configure' changes, but all the
+ `m4' files included in `aclocal.m4' where unknown from `automake'.
+ Now `automake' can just trace the `m4_include's to discover the
+ dependencies.
+
+ `aclocal' also starts using the `--trace' Autoconf option in order
+ to discover used macros more accurately. This will turn out to be
+ very tricky (later releases will improve this) as people had
+ devised many ways to cope with the limitation of previous
+ `aclocal' versions, notably using handwritten `m4_include's:
+ `aclocal' must make sure not to redefine a rule that is already
+ included by such statement.
+
+ Automake also has seen its guts rewritten. Although this rewriting
+ took a lot of efforts, it is only apparent to the users in that
+ some constructions previously disallowed by the implementation now
+ work nicely. Conditionals, Locations, Variable and Rule
+ definitions, Options: these items on which Automake works have
+ been rewritten as separate Perl modules, and documented.

+flaws of various sorts. Here we lay out the different dependency
+tracking methods, their flaws, and their fixes. We conclude with
+recommendations for tool writers, and by indicating future directions
+for dependency tracking work in Automake.

+
+2.1 First Take on Dependency Tracking
+=====================================
+
+Description
+-----------
+
+Our first attempt at automatic dependency tracking was based on the
+method recommended by GNU `make'. (*note Generating Prerequisites
+Automatically: (make)Automatic Prerequisites.)
+
+ This version worked by precomputing dependencies ahead of time. For
+each source file, it had a special `.P' file that held the
+dependencies. There was a rule to generate a `.P' file by invoking the
+compiler appropriately. All such `.P' files were included by the
+`Makefile', thus implicitly becoming dependencies of `Makefile'.
+
+Bugs
+----
+
+This approach had several critical bugs.
+
+ * The code to generate the `.P' file relied on `gcc'. (A
+ limitation, not technically a bug.)
+
+ * The dependency tracking mechanism itself relied on GNU `make'. (A
+ limitation, not technically a bug.)
+
+ * Because each `.P' file was a dependency of `Makefile', this meant
+ that dependency tracking was done eagerly by `make'. For
+ instance, `make clean' would cause all the dependency files to be
+ updated, and then immediately removed. This eagerness also caused
+ problems with some configurations; if a certain source file could
+ not be compiled on a given architecture for some reason,
+ dependency tracking would fail, aborting the entire build.
+
+ * As dependency tracking was done as a pre-pass, compile times were
+ doubled-the compiler had to be run twice per source file.
+
+ * `make dist' re-ran `automake' to generate a `Makefile' that did
+ not have automatic dependency tracking (and that was thus portable
+ to any version of `make'). In order to do this portably, Automake
+ had to scan the dependency files and remove any reference that was
+ to a source file not in the distribution. This process was
+ error-prone. Also, if `make dist' was run in an environment where
+ some object file had a dependency on a source file that was only
+ conditionally created, Automake would generate a `Makefile' that
+ referred to a file that might not appear in the end user's build.
+ A special, hacky mechanism was required to work around this.
+
+Historical Note
+---------------
+
+The code generated by Automake is often inspired by the `Makefile'
+style of a particular author. In the case of the first implementation
+of dependency tracking, I believe the impetus and inspiration was Jim
+Meyering. (I could be mistaken. If you know otherwise feel free to
+correct me.)

+
+2.2 Dependencies As Side Effects
+================================
+
+Description
+-----------
+
+The next refinement of Automake's automatic dependency tracking scheme
+was to implement dependencies as side effects of the compilation. This
+was aimed at solving the most commonly reported problems with the first
+approach. In particular we were most concerned with eliminating the
+weird rebuilding effect associated with make clean.
+
+ In this approach, the `.P' files were included using the `-include'
+command, which let us create these files lazily. This avoided the
+`make clean' problem.
+
+ We only computed dependencies when a file was actually compiled.
+This avoided the performance penalty associated with scanning each file
+twice. It also let us avoid the other problems associated with the
+first, eager, implementation. For instance, dependencies would never
+be generated for a source file that was not compilable on a given
+architecture (because it in fact would never be compiled).
+
+Bugs
+----
+
+ * This approach also relied on the existence of `gcc' and GNU
+ `make'. (A limitation, not technically a bug.)
+
+ * Dependency tracking was still done by the developer, so the
+ problems from the first implementation relating to massaging of
+ dependencies by `make dist' were still in effect.
+
+ * This implementation suffered from the "deleted header file"
+ problem. Suppose a lazily-created `.P' file includes a dependency
+ on a given header file, like this:
+
+ maude.o: maude.c something.h
+
+ Now suppose that you remove `something.h' and update `maude.c' so
+ that this include is no longer needed. If you run `make', you
+ will get an error because there is no way to create `something.h'.
+
+ We fixed this problem in a later release by further massaging the
+ output of `gcc' to include a dummy dependency for each header file.

+
+2.3 Dependencies for the User
+=============================
+
+Description
+-----------
+
+The bugs associated with `make dist', over time, became a real problem.
+Packages using Automake were being built on a large number of
+platforms, and were becoming increasingly complex. Broken dependencies
+were distributed in "portable" `Makefile.in's, leading to user
+complaints. Also, the requirement for `gcc' and GNU `make' was a
+constant source of bug reports. The next implementation of dependency
+tracking aimed to remove these problems.
+
+ We realized that the only truly reliable way to automatically track
+dependencies was to do it when the package itself was built. This
+meant discovering a method portable to any version of make and any
+compiler. Also, we wanted to preserve what we saw as the best point of
+the second implementation: dependency computation as a side effect of
+compilation.
+
+ In the end we found that most modern make implementations support
+some form of include directive. Also, we wrote a wrapper script that
+let us abstract away differences between dependency tracking methods for
+compilers. For instance, some compilers cannot generate dependencies
+as a side effect of compilation. In this case we simply have the
+script run the compiler twice. Currently our wrapper script
+(`depcomp') knows about twelve different compilers (including a
+"compiler" that simply invokes `makedepend' and then the real compiler,
+which is assumed to be a standard Unix-like C compiler with no way to
+do dependency tracking).
+
+Bugs
+----
+
+ * Running a wrapper script for each compilation slows down the build.
+
+ * Many users don't really care about precise dependencies.
+
+ * This implementation, like every other automatic dependency tracking
+ scheme in common use today (indeed, every one we've ever heard of),
+ suffers from the "duplicated new header" bug.
+
+ This bug occurs because dependency tracking tools, such as the
+ compiler, only generate dependencies on the successful opening of a
+ file, and not on every probe.
+
+ Suppose for instance that the compiler searches three directories
+ for a given header, and that the header is found in the third
+ directory. If the programmer erroneously adds a header file with
+ the same name to the first directory, then a clean rebuild from
+ scratch could fail (suppose the new header file is buggy), whereas
+ an incremental rebuild will succeed.
+
+ What has happened here is that people have a misunderstanding of
+ what a dependency is. Tool writers think a dependency encodes
+ information about which files were read by the compiler. However,
+ a dependency must actually encode information about what the
+ compiler tried to do.
+
+ This problem is not serious in practice. Programmers typically do
+ not use the same name for a header file twice in a given project.
+ (At least, not in C or C++. This problem may be more troublesome
+ in Java.) This problem is easy to fix, by modifying dependency
+ generators to record every probe, instead of every successful open.
+
+ * Since Automake generates dependencies as a side effect of
+ compilation, there is a bootstrapping problem when header files
+ are generated by running a program. The problem is that, the
+ first time the build is done, there is no way by default to know
+ that the headers are required, so make might try to run a
+ compilation for which the headers have not yet been built.
+
+ This was also a problem in the previous dependency tracking
+ implementation.
+
+ The current fix is to use `BUILT_SOURCES' to list built headers
+ (*note Sources: (automake)Sources.). This causes them to be built
+ before any other build rules are run. This is unsatisfactory as a
+ general solution, however in practice it seems sufficient for most
+ actual programs.
+
+ This code is used since Automake 1.5.
+
+ In GCC 3.0, we managed to convince the maintainers to add special
+command-line options to help Automake more efficiently do its job. We
+hoped this would let us avoid the use of a wrapper script when
+Automake's automatic dependency tracking was used with `gcc'.
+
+ Unfortunately, this code doesn't quite do what we want. In
+particular, it removes the dependency file if the compilation fails;
+we'd prefer that it instead only touch the file in any way if the
+compilation succeeds.
+
+ Nevertheless, since Automake 1.7, when a recent `gcc' is detected at
+`configure' time, we inline the dependency-generation code and do not
+use the `depcomp' wrapper script. This makes compilations faster for
+those using this compiler (probably our primary user base). The
+counterpart is that because we have to encode two compilation rules in
+`Makefile' (with or without `depcomp'), the produced `Makefile's are
+larger.
+

+
+2.4 Techniques for Computing Dependencies
+=========================================
+
+There are actually several ways for a build tool like Automake to cause
+tools to generate dependencies.
+
+`makedepend'
+ This was a commonly-used method in the past. The idea is to run a
+ special program over the source and have it generate dependency
+ information. Traditional implementations of `makedepend' are not
+ completely precise; ordinarily they were conservative and
+ discovered too many dependencies.
+
+The tool
+ An obvious way to generate dependencies is to simply write the
+ tool so that it can generate the information needed by the build
+ tool. This is also the most portable method. Many compilers have
+ an option to generate dependencies. Unfortunately, not all tools
+ provide such an option.
+
+The file system
+ It is possible to write a special file system that tracks opens,
+ reads, writes, etc, and then feed this information back to the
+ build tool. `clearmake' does this. This is a very powerful
+ technique, as it doesn't require cooperation from the tool.
+ Unfortunately it is also very difficult to implement and also not
+ practical in the general case.
+
+`LD_PRELOAD'
+ Rather than use the file system, one could write a special library
+ to intercept `open' and other syscalls. This technique is also
+ quite powerful, but unfortunately it is not portable enough for
+ use in `automake'.

+
+2.4.1 Recommendations for Tool Writers
+--------------------------------------
+
+We think that every compilation tool ought to be able to generate
+dependencies as a side effect of compilation. Furthermore, at least
+while `make'-based tools are nearly universally in use (at least in the
+free software community), the tool itself should generate dummy
+dependencies for header files, to avoid the deleted header file bug.
+Finally, the tool should generate a dependency for each probe, instead
+of each successful file open, in order to avoid the duplicated new
+header bug.

+
+2.4.2 Future Directions for Dependencies
+----------------------------------------
+
+Currently, only languages and compilers understood by Automake can have
+dependency tracking enabled. We would like to see if it is practical
+(and worthwhile) to let this support be extended by the user to
+languages unknown to Automake.

+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@table @asis
+@item 1994-09-19 First CVS commit.
+
+If we can trust the CVS repository, David J.@tie{}MacKenzie (djm) started
+working on Automake (or AutoMake, as it was spelt then) this Monday.
+
+The first version of the @command{automake} script looks as follows.
+
+@example
+#!/bin/sh
+
+status=0
+
+for makefile
+do
+ if test ! -f $@{makefile@}.am; then
+ echo "automake: $@{makefile@}.am: No such honkin' file"
+ status=1
+ continue
+ fi
+
+ exec 4> $@{makefile@}.in
+
+done
+@end example
+
+From this you can already see that Automake will be about reading
+@file{*.am} file and producing @file{*.in} files. You cannot see
+anything else, but if you also know that David is the one who created
+Autoconf two years before you can guess the rest.
+
+Several commits follow, and by the end of the day Automake is
+reported to work for GNU fileutils and GNU m4.
+
+The modus operandi is the one that is still used today: variable
+assignments in @file{Makefile.am} files trigger injections of
+precanned @file{Makefile} fragments into the generated
+@file{Makefile.in}. The use of @file{Makefile} fragments was inspired
+by the 4.4BSD @command{make} and include files, however Automake aims
+to be portable and to conform to the GNU standards for @file{Makefile}
+variables and targets.
+
+At this point, the most recent release of Autoconf is version 1.11,
+and David is preparing to release Autoconf 2.0 in late October. As a
+matter of fact, he will barely touch Automake after September.
+
+@item 1994-11-05 David MacKenzie's last commit.
+
+At this point Automake is a 200 line portable shell script, plus 332
+lines of @file{Makefile} fragments. In the @file{README}, David
+states his ambivalence between ``portable shell'' and ``more
+appropriate language'':
+
+@quotation
+I wrote it keeping in mind the possibility of it becoming an Autoconf
+macro, so it would run at configure-time. That would slow
+configuration down a bit, but allow users to modify the Makefile.am
+without needing to fetch the AutoMake package. And, the Makefile.in
+files wouldn't need to be distributed. But all of AutoMake would. So
+I might reimplement AutoMake in Perl, m4, or some other more
+appropriate language.
+@end quotation
+
+Automake is described as ``an experimental Makefile generator''.
+There is no documentation. Adventurous users are referred to the
+examples and patches needed to use Automake with GNU m4 1.3, fileutils
+3.9, time 1.6, and development versions of find and indent.
+
+These examples seem to have been lost. However at the time of writing
+(10 years later in September, 2004) the FSF still distributes a
+package that uses this version of Automake: check out GNU termutils
+2.0.
+
+@item 1995-11-12 Tom Tromey's first commit.
+
+After one year of inactivity, Tom Tromey takes over the package.
+Tom was working on GNU cpio back then, and doing this just for fun,
+having trouble finding a project to contribute to. So while hacking
+he wanted to bring the @file{Makefile.in} up to GNU standards. This
+was hard, and one day he saw Automake on @url{ftp://alpha.gnu.org/},
+grabbed it and tried it out.
+
+Tom didn't talk to djm about it until later, just to make sure he
+didn't mind if he made a release. He did a bunch of early releases to
+the Gnits folks.
+
+Gnits was (and still is) totally informal, just a few GNU friends who
+Fran@,cois Pinard knew, who were all interested in making a common
+infrastructure for GNU projects, and shared a similar outlook on how
+to do it. So they were able to make some progress. It came along
+with Autoconf and extensions thereof, and then Automake from David and
+Tom (who were both gnitsians). One of their ideas was to write a
+document paralleling the GNU standards, that was more strict in some
+ways and more detailed. They never finished the GNITS standards, but
+the ideas mostly made their way into Automake.
+
+@item 1995-11-23 Automake 0.20
+
+Besides introducing automatic dependency tracking (@pxref{Dependency
+Tracking Evolution}), this version also supplies a 9-page manual.
+
+At this time @command{aclocal} and @code{AM_INIT_AUTOMAKE} did not
+exist, so many things had to be done by hand. For instance, here is
+what a configure.in (this is the former name of the
+@file{configure.ac} we use today) must contain in order to use
+Automake 0.20:
+
+@example
+PACKAGE=cpio
+VERSION=2.3.911
+AC_DEFINE_UNQUOTED(PACKAGE, "$PACKAGE")
+AC_DEFINE_UNQUOTED(VERSION, "$VERSION")
+AC_SUBST(PACKAGE)
+AC_SUBST(VERSION)
+AC_ARG_PROGRAM
+AC_PROG_INSTALL
+@end example
+
+(Today all of the above is achieved by @code{AC_INIT} and
+@code{AM_INIT_AUTOMAKE}.)
+
+Here is how programs are specified in @file{Makefile.am}:
+
+@example
+PROGRAMS = hello
+hello_SOURCES = hello.c
+@end example
+
+This looks pretty much like what we do today, except the
+@code{PROGRAMS} variable has no directory prefix specifying where
+@file{hello} should be installed: all programs are installed in
+@samp{$(bindir)}. @code{LIBPROGRAMS} can be used to specify programs
+that must be built but not installed (it is called
+@code{noinst_PROGRAMS} nowadays).
+
+Programs can be built conditionally using @code{AC_SUBST}itutions:
+
+@example
+PROGRAMS = @@progs@@
+AM_PROGRAMS = foo bar baz
+@end example
+
+(@code{AM_PROGRAMS} has since then been renamed to
+@code{EXTRA_PROGRAMS}.)
+
+Similarly scripts, static libraries, and data can be built and installed
+using the @code{LIBRARIES}, @code{SCRIPTS}, and @code{DATA} variables.
+However @code{LIBRARIES} were treated a bit specially in that Automake
+did automatically supply the @file{lib} and @file{.a} prefixes.
+Therefore to build @file{libcpio.a}, one had to write
+
+@example
+LIBRARIES = cpio
+cpio_SOURCES = ...
+@end example
+
+Extra files to distribute must be listed in @code{DIST_OTHER} (the
+ancestor of @code{EXTRA_DIST}). Also extra directories that are to be
+distributed should appear in @code{DIST_SUBDIRS}, but the manual
+describes this as a temporary ugly hack (today extra directories should
+also be listed in @code{EXTRA_DIST}, and @code{DIST_SUBDIRS} is used
+for another purpose, @pxref{Conditional Subdirectories, , Conditional
+Subdirectories, automake, GNU Automake}).
+
+@item 1995-11-26 Automake 0.21
+
+In less time than it takes to cook a frozen pizza, Tom rewrites
+Automake using Perl. At this time Perl 5 is only one year old, and
+Perl 4.036 is in use at many sites. Supporting several Perl versions
+has been a source of problems through the whole history of Automake.
+
+If you never used Perl 4, imagine Perl 5 without objects, without
+@samp{my} variables (only dynamically scoped @samp{local} variables),
+without function prototypes, with function calls that needs to be
+prefixed with @samp{&}, etc. Traces of this old style can still be
+found in today's @command{automake}.
+
+@item 1995-11-28 Automake 0.22

+
+Bug fixes.
+
+@item 1995-12-08 Automake 0.24
+@itemx 1995-12-10 Automake 0.25
+
+Releases are raining. 0.24 introduces the uniform naming scheme we
+use today, i.e., @code{bin_PROGRAMS} instead of @code{PROGRAMS},
+@code{noinst_LIBRARIES} instead of @code{LIBLIBRARIES}, etc. (However
+@code{EXTRA_PROGRAMS} does not exist yet, @code{AM_PROGRAMS} is still
+in use; and @code{TEXINFOS} and @code{MANS} still have no directory
+prefixes.) Adding support for prefixes like that was one of the major
+ideas in @command{automake}; it has lasted pretty well.
+
+AutoMake is renamed to Automake (Tom seems to recall it was Fran@,cois
+Pinard's doing).
+
+0.25 fixes a Perl 4 portability bug.
+
+@item 1995-12-18 Jim Meyering starts using Automake in GNU Textutils.

+
+@item 1996-01-03 Automake 0.26
+@itemx 1996-01-03 Automake 0.27
+
+Of the many changes and suggestions sent by Fran@,cois Pinard and
+included in 0.26, perhaps the most important is the advice that to
+ease customization a user rule or variable definition should always
+override an Automake rule or definition.
+
+Gordon Matzigkeit and Jim Meyering are two other early contributors
+that have been sending fixes.
+
+0.27 fixes yet another Perl 4 portability bug.
+
+@item 1996-01-13 Automake 0.28
+
+Automake starts scanning @file{configure.in} for @code{LIBOBJS}
+support. This is an important step because until this version
+Automake only knew about the @file{Makefile.am}s it processed.
+@file{configure.in} was Autoconf's world and the link between Autoconf
+and Automake had to be done by the @file{Makefile.am} author. For
+instance, if @file{config.h} was generated by @file{configure}, it was the
+package maintainer's responsibility to define the @code{CONFIG_HEADER}
+variable in each @file{Makefile.am}.
+
+Succeeding releases will rely more and more on scanning
+@file{configure.in} to better automate the Autoconf integration.
+
+0.28 also introduces the @code{AUTOMAKE_OPTIONS} variable and the
+@option{--gnu} and @option{--gnits} options, the latter being stricter.
+
+@item 1996-02-07 Automake 0.29
+
+Thanks to @file{configure.in} scanning, @code{CONFIG_HEADER} is gone,
+and rebuild rules for @file{configure}-generated file are
+automatically output.
+
+@code{TEXINFOS} and @code{MANS} converted to the uniform naming
+scheme.
+
+@item 1996-02-24 Automake 0.30
+
+The test suite is born. It contains 9 tests. From now on test cases
+will be added pretty regularly (@pxref{Releases}), and this proved to
+be really helpful later on.
+
+@code{EXTRA_PROGRAMS} finally replaces @code{AM_PROGRAMS}.
+
+All the third-party Autoconf macros, written mostly by Fran@,cois
+Pinard (and later Jim Meyering), are distributed in Automake's
+hand-written @file{aclocal.m4} file. Package maintainers are expected
+to extract the necessary macros from this file. (In previous versions
+you had to copy and paste them from the manual...)
+
+@item 1996-03-11 Automake 0.31
+
+The test suite in 0.30 was run via a long @code{check-local} rule. Upon
+Ulrich Drepper's suggestion, 0.31 makes it an Automake rule output
+whenever the @code{TESTS} variable is defined.
+
+@code{DIST_OTHER} is renamed to @code{EXTRA_DIST}, and the @code{check_}
+prefix is introduced. The syntax is now the same as today.
+
+@item 1996-03-15 Gordon Matzigkeit starts writing libtool.
+
+@item 1996-04-27 Automake 0.32
+
+@code{-hook} targets are introduced; an idea from Dieter Baron.
+
+@file{*.info} files, which were output in the build directory are
+now built in the source directory, because they are distributed. It
+seems these files like to move back and forth as that will happen
+again in future versions.
+
+@item 1996-05-18 Automake 0.33
+
+Gord Matzigkeit's main two contributions:
+
+@itemize
+@item very preliminary libtool support
+@item the distcheck rule
+@end itemize
+
+Although they were very basic at this point, these are probably
+among the top features for Automake today.
+
+Jim Meyering also provides the infamous @code{jm_MAINTAINER_MODE}, since
+then renamed to @code{AM_MAINTAINER_MODE} and abandoned by its author
+(@pxref{maintainer-mode, , maintainer-mode, automake, GNU Automake}).
+
+@item 1996-05-28 Automake 1.0
+
+After only six months of heavy development, the @command{automake} script is
+3134 lines long, plus 973 lines of @file{Makefile} fragments. The
+package has 30 pages of documentation, and 38 test cases.
+@file{aclocal.m4} contains 4 macros.
+
+From now on and until version 1.4, new releases will occur at a rate
+of about one a year. 1.1 did not exist, actually 1.1b to 1.1p have
+been the name of beta releases for 1.2. This is the first time
+Automake uses suffix letters to designate beta releases, a habit that
+lasts.
+
+@item 1996-10-10 Kevin Dalley packages Automake 1.0 for Debian GNU/Linux.
+
+@item 1996-11-26 David J.@tie{}MacKenzie releases Autoconf 2.12.
+
+Between June and October, the Autoconf development is almost stalled.
+Roland McGrath has been working at the beginning of the year. David
+comes back in November to release 2.12, but he won't touch Autoconf
+anymore after this year, and Autoconf then really stagnates. The
+desolate Autoconf @file{ChangeLog} for 1997 lists only 7 commits.
+
+@item 1997-02-28 @email{automake@@gnu.ai.mit.edu} list alive
+
+The mailing list is announced as follows:
+@smallexample
+I've created the "automake" mailing list. It is
+"automake@@gnu.ai.mit.edu". Administrivia, as always, to
+automake-request@@gnu.ai.mit.edu.
+
+The charter of this list is discussion of automake, autoconf, and
+other configuration/portability tools (e.g., libtool). It is expected
+that discussion will range from pleas for help all the way up to
+patches.
+
+This list is archived on the FSF machines. Offhand I don't know if
+you can get the archive without an account there.
+
+This list is open to anybody who wants to join. Tell all your
+friends!
+-- Tom Tromey
+@end smallexample
+
+Before that people were discussing Automake privately, on the Gnits
+mailing list (which is not public either), and less frequently on
+@code{gnu.misc.discuss}.
+
+@code{gnu.ai.mit.edu} is now @code{gnu.org}, in case you never
+noticed. The archives of the early years of the
+@code{automake@@gnu.org} list have been lost, so today it is almost
+impossible to find traces of discussions that occurred before 1999.
+This has been annoying more than once, as such discussions can be
+useful to understand the rationale behind a piece of uncommented code
+that was introduced back then.
+
+@item 1997-06-22 Automake 1.2
+
+Automake developments continues, and more and more new Autoconf macros
+are required. Distributing them in @file{aclocal.m4} and requiring
+people to browse this file to extract the relevant macros becomes
+uncomfortable. Ideally, some of them should be contributed to
+Autoconf so that they can be used directly, however Autoconf is
+currently inactive. Automake 1.2 consequently introduces
+@command{aclocal} (@command{aclocal} was actually started on
+1996-07-28), a tool that automatically constructs an @file{aclocal.m4}
+file from a repository of third-party macros. Because Autoconf has
+stalled, Automake also becomes a kind of repository for such
+third-party macros, even macros completely unrelated to Automake (for
+instance macros that fix broken Autoconf macros).
+
+The 1.2 release contains 20 macros, including the
+@code{AM_INIT_AUTOMAKE} macro that simplifies the creation of
+@file{configure.in}.
+
+Libtool is fully supported using @code{*_LTLIBRARIES}.
+
+The missing script is introduced by Fran@,cois Pinard; it is meant
+to be a better solution than @code{AM_MAINTAINER_MODE}
+(@pxref{maintainer-mode, , maintainer-mode, automake, GNU Automake}).
+
+Conditionals support was implemented by Ian Lance Taylor. At the
+time, Tom and Ian were working on an internal project at Cygnus. They
+were using ILU, which is pretty similar to CORBA@. They wanted to
+integrate ILU into their build, which was all @file{configure}-based,
+and Ian thought that adding conditionals to @command{automake} was
+simpler than doing all the work in @file{configure} (which was the
+standard at the time). So this was actually funded by Cygnus.
+
+This very useful but tricky feature will take a lot of time to
+stabilize. (At the time this text is written, there are still
+primaries that have not been updated to support conditional
+definitions in Automake 1.9.)
+
+The @command{automake} script has almost doubled: 6089 lines of Perl,
+plus 1294 lines of @file{Makefile} fragments.
+
+@item 1997-07-08 Gordon Matzigkeit releases Libtool 1.0.
+
+@item 1998-04-05 Automake 1.3
+
+This is a small advance compared to 1.2.
+It adds support for assembly, and preliminary support for Java.
+
+Perl 5.004_04 is out, but fixes to support Perl 4 are still
+regularly submitted whenever Automake breaks it.
+
+@item 1998-09-06 @code{sourceware.cygnus.com} is on-line.
+
+Sourceware was setup by Jason Molenda to host open source projects.
+
+@item 1998-09-19 Automake CVS repository moved to @code{sourceware.cygnus.com}
+@itemx 1998-10-26 @code{sourceware.cygnus.com} announces it hosts Automake:
+Automake is now hosted on @code{sourceware.cygnus.com}. It has a
+publicly accessible CVS repository. This CVS repository is a copy of
+the one Tom was using on his machine, which in turn is based on
+a copy of the CVS repository of David MacKenzie. This is why we still
+have to full source history. (Automake was on Sourceware until 2007-10-29,
+when it moved to a git repository on @code{savannah.gnu.org},
+but the Sourceware host had been renamed to @code{sources.redhat.com}.)
+
+The oldest file in the administrative directory of the CVS repository
+that was created on Sourceware is dated 1998-09-19, while the
+announcement that @command{automake} and @command{autoconf} had joined
+@command{sourceware} was made on 1998-10-26. They were among the
+first projects to be hosted there.
+
+The heedful reader will have noticed Automake was exactly 4 years old
+on 1998-09-19.
+
+@item 1999-01-05 Ben Elliston releases Autoconf 2.13.
+
+@item 1999-01-14 Automake 1.4
+
+This release adds support for Fortran 77 and for the @code{include}
+statement. Also, @samp{+=} assignments are introduced, but it is
+still quite easy to fool Automake when mixing this with conditionals.
+
+These two releases, Automake 1.4 and Autoconf 2.13 make a duo that
+will be used together for years.
+
+@command{automake} is 7228 lines, plus 1591 lines of Makefile
+fragment, 20 macros (some 1.3 macros were finally contributed back to
+Autoconf), 197 test cases, and 51 pages of documentation.
+
+@item 1999-03-27 The @code{user-dep-branch} is created on the CVS repository.
+
+This implements a new dependency tracking schemed that should be
+able to handle automatic dependency tracking using any compiler (not
+just gcc) and any make (not just GNU @command{make}). In addition,
+the new scheme should be more reliable than the old one, as
+dependencies are generated on the end user's machine. Alexandre Oliva
+creates depcomp for this purpose.
+
+@xref{Dependency Tracking Evolution}, for more details about the
+evolution of automatic dependency tracking in Automake.
+
+@item 1999-11-21 The @code{user-dep-branch} is merged into the main trunk.
+
+This was a huge problem since we also had patches going in on the
+trunk. The merge took a long time and was very painful.
+
+@item 2000-05-10
+
+Since September 1999 and until 2003, Akim Demaille will be zealously
+revamping Autoconf.
+
+@quotation
+I think the next release should be called "3.0".@*
+Let's face it: you've basically rewritten autoconf.@*
+Every weekend there are 30 new patches.@*
+I don't see how we could call this "2.15" with a straight face.@*
+-- Tom Tromey on @email{autoconf@@gnu.org}
+@end quotation
+
+Actually Akim works like a submarine: he will pile up patches while he
+works off-line during the weekend, and flush them in batch when he
+resurfaces on Monday.
+
+@item 2001-01-24
+
+On this Wednesday, Autoconf 2.49c, the last beta before Autoconf 2.50
+is out, and Akim has to find something to do during his week-end :)
+
+@item 2001-01-28
+
+Akim sends a batch of 14 patches to @email{automake@@gnu.org}.
+
+@quotation
+Aiieeee! I was dreading the day that the Demaillator turned his
+sights on automake@dots{} and now it has arrived! -- Tom Tromey
+@end quotation
+
+It's only the beginning: in two months he will send 192 patches. Then
+he would slow down so Tom can catch up and review all this. Initially
+Tom actually read all these patches, then he probably trustingly
+answered OK to most of them, and finally gave up and let Akim apply
+whatever he wanted. There was no way to keep up with that patch rate.
+
+@quotation
+Anyway the patch below won't apply since it predates Akim's
+sourcequake; I have yet to figure where the relevant passage has
+been moved :) -- Alexandre Duret-Lutz
+@end quotation
+
+All these patches were sent to and discussed on
+@email{automake@@gnu.org}, so subscribed users were literally drowning in
+technical mails. Eventually, the @email{automake-patches@@gnu.org}
+mailing list was created in May.
+
+Year after year, Automake had drifted away from its initial design:
+construct @file{Makefile.in} by assembling various @file{Makefile}
+fragments. In 1.4, lots of @file{Makefile} rules are being emitted at
+various places in the @command{automake} script itself; this does not
+help ensuring a consistent treatment of these rules (for instance
+making sure that user-defined rules override Automake's own rules).
+One of Akim's goal was moving all these hard-coded rules to separate
+@file{Makefile} fragments, so the logic could be centralized in a
+@file{Makefile} fragment processor.
+
+Another significant contribution of Akim is the interface with the
+``trace'' feature of Autoconf. The way to scan @file{configure.in} at
+this time was to read the file and grep the various macro of interest
+to Automake. Doing so could break in many unexpected ways; @command{automake}
+could miss some definition (for instance @samp{AC_SUBST([$1], [$2])}
+where the arguments are known only when M4 is run), or conversely it
+could detect some macro that was not expanded (because it is called
+conditionally). In the CVS version of Autoconf, Akim had implemented
+the @option{--trace} option, which provides accurate information about
+where macros are actually called and with what arguments. Akim will
+equip Automake with a second @file{configure.in} scanner that uses
+this @option{--trace} interface. Since it was not sensible to drop the
+Autoconf 2.13 compatibility yet, this experimental scanner was only
+used when an environment variable was set, the traditional
+grep-scanner being still the default.
+
+@item 2001-04-25 Gary V.@tie{}Vaughan releases Libtool 1.4
+
+It has been more than two years since Automake 1.4, CVS Automake has
+suffered lot's of heavy changes and still is not ready for release.
+Libtool 1.4 had to be distributed with a patch against Automake 1.4.
+
+@item 2001-05-08 Automake 1.4-p1
+@itemx 2001-05-24 Automake 1.4-p2
+
+Gary V.@tie{}Vaughan, the principal Libtool maintainer, makes a ``patch
+release'' of Automake:
+
+@quotation
+The main purpose of this release is to have a stable automake
+which is compatible with the latest stable libtool.
+@end quotation
+
+The release also contains obvious fixes for bugs in Automake 1.4,
+some of which were reported almost monthly.
+
+@item 2001-05-21 Akim Demaille releases Autoconf 2.50
+
+@item 2001-06-07 Automake 1.4-p3
+@itemx 2001-06-10 Automake 1.4-p4
+@itemx 2001-07-15 Automake 1.4-p5
+
+Gary continues his patch-release series. These also add support for
+some new Autoconf 2.50 idioms. Essentially, Autoconf now advocates
+@file{configure.ac} over @file{configure.in}, and it introduces a new
+syntax for @code{AC_OUTPUT}ing files.
+
+@item 2001-08-23 Automake 1.5
+
+A major and long-awaited release, that comes more than two years after
+1.4. It brings many changes, among which:
+@itemize
+@item The new dependency tracking scheme that uses @command{depcomp}.
+Aside from the improvement on the dependency tracking itself
+(@pxref{Dependency Tracking Evolution}), this also streamlines the use
+of @command{automake}-generated @file{Makefile.in}s as the @file{Makefile.in}s
+used during development are now the same as those used in
+distributions. Before that the @file{Makefile.in}s generated for
+maintainers required GNU @command{make} and GCC, they were different
+from the portable @file{Makefile} generated for distribution; this was
+causing some confusion.
+
+@item Support for per-target compilation flags.
+
+@item Support for reference to files in subdirectories in most
+@file{Makefile.am} variables.
+
+@item Introduction of the @code{dist_}, @code{nodist_}, and @code{nobase_}
+prefixes.
+@item Perl 4 support is finally dropped.
+@end itemize
+
+1.5 did break several packages that worked with 1.4. Enough so that
+Linux distributions could not easily install the new Automake version
+without breaking many of the packages for which they had to run
+@command{automake}.
+
+Some of these breakages were effectively bugs that would eventually be
+fixed in the next release. However, a lot of damage was caused by
+some changes made deliberately to render Automake stricter on some
+setup we did consider bogus. For instance, @samp{make distcheck} was
+improved to check that @samp{make uninstall} did remove all the files
+@samp{make install} installed, that @samp{make distclean} did not omit
+some file, and that a VPATH build would work even if the source
+directory was read-only. Similarly, Automake now rejects multiple
+definitions of the same variable (because that would mix very badly
+with conditionals), and @samp{+=} assignments with no previous
+definition. Because these changes all occurred suddenly after 1.4 had
+been established for more than two years, it hurt users.
+
+To make matter worse, meanwhile Autoconf (now at version 2.52) was
+facing similar troubles, for similar reasons.
+
+@item 2002-03-05 Automake 1.6
+
+This release introduced versioned installation (@pxref{API Versioning, ,
+API Versioning, automake, GNU Automake}). This was mainly pushed by
+Havoc Pennington, taking the GNOME source tree as motive: due to
+incompatibilities between the autotools it's impossible for the GNOME
+packages to switch to Autoconf 2.53 and Automake 1.5 all at once, so
+they are currently stuck with Autoconf 2.13 and Automake 1.4.
+
+The idea was to call this version @file{automake-1.6}, call all its
+bug-fix versions identically, and switch to @file{automake-1.7} for
+the next release that adds new features or changes some rules. This
+scheme implies maintaining a bug-fix branch in addition to the
+development trunk, which means more work from the maintainer, but
+providing regular bug-fix releases proved to be really worthwhile.
+
+Like 1.5, 1.6 also introduced a bunch of incompatibilities, intentional or
+not. Perhaps the more annoying was the dependence on the newly
+released Autoconf 2.53. Autoconf seemed to have stabilized enough
+since its explosive 2.50 release and included changes required to fix
+some bugs in Automake. In order to upgrade to Automake 1.6, people
+now had to upgrade Autoconf too; for some packages it was no picnic.
+
+While versioned installation helped people to upgrade, it also
+unfortunately allowed people not to upgrade. At the time of writing,
+some Linux distributions are shipping packages for Automake 1.4, 1.5,
+1.6, 1.7, 1.8, and 1.9. Most of these still install 1.4 by default.
+Some distribution also call 1.4 the ``stable'' version, and present
+``1.9'' as the development version; this does not really makes sense
+since 1.9 is way more solid than 1.4. All this does not help the
+newcomer.
+
+@item 2002-04-11 Automake 1.6.1
+
+1.6, and the upcoming 1.4-p6 release were the last release by Tom.
+This one and those following will be handled by Alexandre
+Duret-Lutz. Tom is still around, and will be there until about 1.7,
+but his interest into Automake is drifting away towards projects like
+@command{gcj}.
+
+Alexandre has been using Automake since 2000, and started to
+contribute mostly on Akim's incitement (Akim and Alexandre have been
+working in the same room from 1999 to 2002). In 2001 and 2002 he had
+a lot of free time to enjoy hacking Automake.

+
+Two releases on the same day. 1.6.3 is a bug-fix release.
+
+Tom Tromey backported the versioned installation mechanism on the 1.4
+branch, so that Automake 1.6.x and Automake 1.4-p6 could be installed
+side by side. Another request from the GNOME folks.

+
+@item 2003-10-26 Automake on screen
+
+Episode 49, `Repercussions', in the third season of the `Alias' TV
+show is first aired.
+
+Marshall, one of the characters, is working on a computer virus that he
+has to modify before it gets into the wrong hands or something like
+that. The screenshots you see do not show any program code, they show
+a @file{Makefile.in} generated by automake...
+
+@item 2003-11-09 Automake 1.7.9
+
+@item 2003-12-10 Automake 1.8
+
+The most striking update is probably that of @command{aclocal}.
+
+@command{aclocal} now uses @code{m4_include} in the produced
+@file{aclocal.m4} when the included macros are already distributed
+with the package (an idiom used in many packages), which reduces code
+duplication. Many people liked that, but in fact this change was
+really introduced to fix a bug in rebuild rules: @file{Makefile.in}
+must be rebuilt whenever a dependency of @file{configure} changes, but
+all the @file{m4} files included in @file{aclocal.m4} where unknown
+from @command{automake}. Now @command{automake} can just trace the
+@code{m4_include}s to discover the dependencies.
+
+@command{aclocal} also starts using the @option{--trace} Autoconf option
+in order to discover used macros more accurately. This will turn out
+to be very tricky (later releases will improve this) as people had
+devised many ways to cope with the limitation of previous
+@command{aclocal} versions, notably using handwritten
+@code{m4_include}s: @command{aclocal} must make sure not to redefine a
+rule that is already included by such statement.
+
+Automake also has seen its guts rewritten. Although this rewriting
+took a lot of efforts, it is only apparent to the users in that some
+constructions previously disallowed by the implementation now work
+nicely. Conditionals, Locations, Variable and Rule definitions,
+Options: these items on which Automake works have been rewritten as
+separate Perl modules, and documented.

+Automake 1.4 and custom build rules (1.4 did not support compiled

+@chapter Evolution of Automatic Dependency Tracking
+
+Over the years Automake has deployed three different dependency
+tracking methods. Each method, including the current one, has had
+flaws of various sorts. Here we lay out the different dependency
+tracking methods, their flaws, and their fixes. We conclude with
+recommendations for tool writers, and by indicating future directions
+for dependency tracking work in Automake.

+@node First Take on Dependencies
+@section First Take on Dependency Tracking
+@unnumberedsubsec Description
+
+Our first attempt at automatic dependency tracking was based on the
+method recommended by GNU @command{make}. (@pxref{Automatic
+Prerequisites, , Generating Prerequisites Automatically, make, The GNU
+make Manual})
+
+This version worked by precomputing dependencies ahead of time. For
+each source file, it had a special @file{.P} file that held the
+dependencies. There was a rule to generate a @file{.P} file by
+invoking the compiler appropriately. All such @file{.P} files were
+included by the @file{Makefile}, thus implicitly becoming dependencies
+of @file{Makefile}.
+
+@unnumberedsubsec Bugs
+
+This approach had several critical bugs.
+
+@itemize
+@item
+The code to generate the @file{.P} file relied on @command{gcc}.
+(A limitation, not technically a bug.)
+@item
+The dependency tracking mechanism itself relied on GNU @command{make}.
+(A limitation, not technically a bug.)
+@item
+Because each @file{.P} file was a dependency of @file{Makefile}, this
+meant that dependency tracking was done eagerly by @command{make}.
+For instance, @samp{make clean} would cause all the dependency files
+to be updated, and then immediately removed. This eagerness also
+caused problems with some configurations; if a certain source file
+could not be compiled on a given architecture for some reason,
+dependency tracking would fail, aborting the entire build.
+@item
+As dependency tracking was done as a pre-pass, compile times were
+doubled--the compiler had to be run twice per source file.
+@item
+@samp{make dist} re-ran @command{automake} to generate a
+@file{Makefile} that did not have automatic dependency tracking (and
+that was thus portable to any version of @command{make}). In order to
+do this portably, Automake had to scan the dependency files and remove
+any reference that was to a source file not in the distribution.
+This process was error-prone. Also, if @samp{make dist} was run in an
+environment where some object file had a dependency on a source file
+that was only conditionally created, Automake would generate a
+@file{Makefile} that referred to a file that might not appear in the
+end user's build. A special, hacky mechanism was required to work
+around this.
+@end itemize
+
+@unnumberedsubsec Historical Note
+
+The code generated by Automake is often inspired by the
+@file{Makefile} style of a particular author. In the case of the first
+implementation of dependency tracking, I believe the impetus and
+inspiration was Jim Meyering. (I could be mistaken. If you know
+otherwise feel free to correct me.)
+
+@node Dependencies As Side Effects
+@section Dependencies As Side Effects
+@unnumberedsubsec Description
+
+The next refinement of Automake's automatic dependency tracking scheme
+was to implement dependencies as side effects of the compilation.
+This was aimed at solving the most commonly reported problems with the
+first approach. In particular we were most concerned with eliminating
+the weird rebuilding effect associated with make clean.
+
+In this approach, the @file{.P} files were included using the
+@code{-include} command, which let us create these files lazily. This
+avoided the @samp{make clean} problem.
+
+We only computed dependencies when a file was actually compiled. This
+avoided the performance penalty associated with scanning each file
+twice. It also let us avoid the other problems associated with the
+first, eager, implementation. For instance, dependencies would never
+be generated for a source file that was not compilable on a given
+architecture (because it in fact would never be compiled).
+
+@unnumberedsubsec Bugs
+
+@itemize
+@item
+This approach also relied on the existence of @command{gcc} and GNU
+@command{make}. (A limitation, not technically a bug.)
+@item
+Dependency tracking was still done by the developer, so the problems
+from the first implementation relating to massaging of dependencies by
+@samp{make dist} were still in effect.
+@item
+This implementation suffered from the ``deleted header file'' problem.
+Suppose a lazily-created @file{.P} file includes a dependency on a
+given header file, like this:
+
+@example
+maude.o: maude.c something.h
+@end example
+
+Now suppose that you remove @file{something.h} and update @file{maude.c}
+so that this include is no longer needed. If you run @command{make},
+you will get an error because there is no way to create
+@file{something.h}.
+
+We fixed this problem in a later release by further massaging the
+output of @command{gcc} to include a dummy dependency for each header
+file.
+@end itemize
+
+@node Dependencies for the User
+@section Dependencies for the User
+@unnumberedsubsec Description
+
+The bugs associated with @samp{make dist}, over time, became a real
+problem. Packages using Automake were being built on a large number
+of platforms, and were becoming increasingly complex. Broken
+dependencies were distributed in ``portable'' @file{Makefile.in}s,
+leading to user complaints. Also, the requirement for @command{gcc}
+and GNU @command{make} was a constant source of bug reports. The next
+implementation of dependency tracking aimed to remove these problems.
+
+We realized that the only truly reliable way to automatically track
+dependencies was to do it when the package itself was built. This
+meant discovering a method portable to any version of make and any
+compiler. Also, we wanted to preserve what we saw as the best point
+of the second implementation: dependency computation as a side effect
+of compilation.
+
+In the end we found that most modern make implementations support some
+form of include directive. Also, we wrote a wrapper script that let
+us abstract away differences between dependency tracking methods for
+compilers. For instance, some compilers cannot generate dependencies
+as a side effect of compilation. In this case we simply have the
+script run the compiler twice. Currently our wrapper script
+(@command{depcomp}) knows about twelve different compilers (including
+a "compiler" that simply invokes @command{makedepend} and then the
+real compiler, which is assumed to be a standard Unix-like C compiler
+with no way to do dependency tracking).
+
+@unnumberedsubsec Bugs
+
+@itemize
+@item
+Running a wrapper script for each compilation slows down the build.
+@item
+Many users don't really care about precise dependencies.
+@item
+This implementation, like every other automatic dependency tracking
+scheme in common use today (indeed, every one we've ever heard of),
+suffers from the ``duplicated new header'' bug.
+
+This bug occurs because dependency tracking tools, such as the
+compiler, only generate dependencies on the successful opening of a
+file, and not on every probe.
+
+Suppose for instance that the compiler searches three directories for
+a given header, and that the header is found in the third directory.
+If the programmer erroneously adds a header file with the same name to
+the first directory, then a clean rebuild from scratch could fail
+(suppose the new header file is buggy), whereas an incremental rebuild
+will succeed.
+
+What has happened here is that people have a misunderstanding of what
+a dependency is. Tool writers think a dependency encodes information
+about which files were read by the compiler. However, a dependency
+must actually encode information about what the compiler tried to do.
+
+This problem is not serious in practice. Programmers typically do not
+use the same name for a header file twice in a given project. (At
+least, not in C or C++. This problem may be more troublesome in
+Java.) This problem is easy to fix, by modifying dependency
+generators to record every probe, instead of every successful open.
+
+@item
+Since Automake generates dependencies as a side effect of compilation,
+there is a bootstrapping problem when header files are generated by
+running a program. The problem is that, the first time the build is
+done, there is no way by default to know that the headers are
+required, so make might try to run a compilation for which the headers
+have not yet been built.
+
+This was also a problem in the previous dependency tracking implementation.
+
+The current fix is to use @code{BUILT_SOURCES} to list built headers
+(@pxref{Sources, , Sources, automake, GNU Automake}). This causes them
+to be built before any other build rules are run. This is unsatisfactory
+as a general solution, however in practice it seems sufficient for most
+actual programs.
+@end itemize
+
+This code is used since Automake 1.5.
+
+In GCC 3.0, we managed to convince the maintainers to add special
+command-line options to help Automake more efficiently do its job. We
+hoped this would let us avoid the use of a wrapper script when
+Automake's automatic dependency tracking was used with @command{gcc}.
+
+Unfortunately, this code doesn't quite do what we want. In
+particular, it removes the dependency file if the compilation fails;
+we'd prefer that it instead only touch the file in any way if the
+compilation succeeds.
+
+Nevertheless, since Automake 1.7, when a recent @command{gcc} is
+detected at @command{configure} time, we inline the
+dependency-generation code and do not use the @command{depcomp}
+wrapper script. This makes compilations faster for those using this
+compiler (probably our primary user base). The counterpart is that
+because we have to encode two compilation rules in @file{Makefile}
+(with or without @command{depcomp}), the produced @file{Makefile}s are
+larger.
+
+@node Techniques for Dependencies
+@section Techniques for Computing Dependencies
+
+There are actually several ways for a build tool like Automake to
+cause tools to generate dependencies.
+
+@table @asis
+@item @command{makedepend}
+This was a commonly-used method in the past. The idea is to run a
+special program over the source and have it generate dependency
+information. Traditional implementations of @command{makedepend} are
+not completely precise; ordinarily they were conservative and
+discovered too many dependencies.
+@item The tool
+An obvious way to generate dependencies is to simply write the tool so
+that it can generate the information needed by the build tool. This is
+also the most portable method. Many compilers have an option to
+generate dependencies. Unfortunately, not all tools provide such an
+option.
+@item The file system
+It is possible to write a special file system that tracks opens,
+reads, writes, etc, and then feed this information back to the build
+tool. @command{clearmake} does this. This is a very powerful
+technique, as it doesn't require cooperation from the
+tool. Unfortunately it is also very difficult to implement and also
+not practical in the general case.
+@item @code{LD_PRELOAD}
+Rather than use the file system, one could write a special library to
+intercept @code{open} and other syscalls. This technique is also quite
+powerful, but unfortunately it is not portable enough for use in
+@command{automake}.

+@node Recommendations for Tool Writers
+@subsection Recommendations for Tool Writers
+
+We think that every compilation tool ought to be able to generate
+dependencies as a side effect of compilation. Furthermore, at least
+while @command{make}-based tools are nearly universally in use (at
+least in the free software community), the tool itself should generate
+dummy dependencies for header files, to avoid the deleted header file
+bug. Finally, the tool should generate a dependency for each probe,
+instead of each successful file open, in order to avoid the duplicated
+new header bug.
+
+@node Future Directions for Dependencies
+@subsection Future Directions for Dependencies
+
+Currently, only languages and compilers understood by Automake can
+have dependency tracking enabled. We would like to see if it is
+practical (and worthwhile) to let this support be extended by the user
+to languages unknown to Automake.

+1 Introduction
+**************
+
+Automake is a tool for automatically generating `Makefile.in's from
+files called `Makefile.am'. Each `Makefile.am' is basically a series
+of `make' variable definitions(1), with rules being thrown in
+occasionally. The generated `Makefile.in's are compliant with the GNU
+Makefile standards.
+
+ The GNU Makefile Standards Document (*note Makefile Conventions:
+(standards)Makefile Conventions.) is long, complicated, and subject to
+change. The goal of Automake is to remove the burden of Makefile
+maintenance from the back of the individual GNU maintainer (and put it
+on the back of the Automake maintainers).
+
+ The typical Automake input file is simply a series of variable
+definitions. Each such file is processed to create a `Makefile.in'.
+There should generally be one `Makefile.am' per directory of a project.
+

+2 An Introduction to the Autotools
+**********************************
+
+If you are new to Automake, maybe you know that it is part of a set of
+tools called _The Autotools_. Maybe you've already delved into a
+package full of files named `configure', `configure.ac', `Makefile.in',
+`Makefile.am', `aclocal.m4', ..., some of them claiming to be
+_generated by_ Autoconf or Automake. But the exact purpose of these
+files and their relations is probably fuzzy. The goal of this chapter
+is to introduce you to this machinery, to show you how it works and how
+powerful it is. If you've never installed or seen such a package, do
+not worry: this chapter will walk you through it.
+
+ If you need some teaching material, more illustrations, or a less
+`automake'-centered continuation, some slides for this introduction are
+available in Alexandre Duret-Lutz's Autotools Tutorial
+(http://www.lrde.epita.fr/~adl/autotools.html). This chapter is the
+written version of the first part of his tutorial.

+
+2.1 Introducing the GNU Build System
+====================================
+
+It is a truth universally acknowledged, that as a developer in
+possession of a new package, you must be in want of a build system.
+
+ In the Unix world, such a build system is traditionally achieved
+using the command `make' (*note Overview: (make)Top.). You express the
+recipe to build your package in a `Makefile'. This file is a set of
+rules to build the files in the package. For instance the program
+`prog' may be built by running the linker on the files `main.o',
+`foo.o', and `bar.o'; the file `main.o' may be built by running the
+compiler on `main.c'; etc. Each time `make' is run, it reads
+`Makefile', checks the existence and modification time of the files
+mentioned, decides what files need to be built (or rebuilt), and runs
+the associated commands.
+
+ When a package needs to be built on a different platform than the one
+it was developed on, its `Makefile' usually needs to be adjusted. For
+instance the compiler may have another name or require more options.
+In 1991, David J. MacKenzie got tired of customizing `Makefile' for the
+20 platforms he had to deal with. Instead, he handcrafted a little
+shell script called `configure' to automatically adjust the `Makefile'
+(*note Genesis: (autoconf)Genesis.). Compiling his package was now as
+simple as running `./configure && make'.
+
+ Today this process has been standardized in the GNU project. The GNU
+Coding Standards (*note The Release Process: (standards)Managing
+Releases.) explains how each package of the GNU project should have a
+`configure' script, and the minimal interface it should have. The
+`Makefile' too should follow some established conventions. The result?
+A unified build system that makes all packages almost indistinguishable
+by the installer. In its simplest scenario, all the installer has to
+do is to unpack the package, run `./configure && make && make install',
+and repeat with the next package to install.
+
+ We call this build system the "GNU Build System", since it was grown
+out of the GNU project. However it is used by a vast number of other
+packages: following any existing convention has its advantages.
+
+ The Autotools are tools that will create a GNU Build System for your
+package. Autoconf mostly focuses on `configure' and Automake on
+`Makefile's. It is entirely possible to create a GNU Build System
+without the help of these tools. However it is rather burdensome and
+error-prone. We will discuss this again after some illustration of the
+GNU Build System in action.
+

+
+2.2 Use Cases for the GNU Build System
+======================================
+
+In this section we explore several use cases for the GNU Build System.
+You can replay all these examples on the `amhello-1.0.tar.gz' package
+distributed with Automake. If Automake is installed on your system,
+you should find a copy of this file in
+`PREFIX/share/doc/automake/amhello-1.0.tar.gz', where PREFIX is the
+installation prefix specified during configuration (PREFIX defaults to
+`/usr/local', however if Automake was installed by some GNU/Linux
+distribution it most likely has been set to `/usr'). If you do not
+have a copy of Automake installed, you can find a copy of this file
+inside the `doc/' directory of the Automake package.
+
+ Some of the following use cases present features that are in fact
+extensions to the GNU Build System. Read: they are not specified by
+the GNU Coding Standards, but they are nonetheless part of the build
+system created by the Autotools. To keep things simple, we do not
+point out the difference. Our objective is to show you many of the
+features that the build system created by the Autotools will offer to
+you.

+File: automake.info, Node: Basic Installation, Next: Standard Targets, Up: Use Cases
+
+2.2.1 Basic Installation
+------------------------
+
+The most common installation procedure looks as follows.
+
+ ~ % tar zxf amhello-1.0.tar.gz
+ ~ % cd amhello-1.0
+ ~/amhello-1.0 % ./configure
+ ...
+ config.status: creating Makefile
+ config.status: creating src/Makefile
+ ...
+ ~/amhello-1.0 % make
+ ...
+ ~/amhello-1.0 % make check
+ ...
+ ~/amhello-1.0 % su
+ Password:
+ /home/adl/amhello-1.0 # make install
+ ...
+ /home/adl/amhello-1.0 # exit
+ ~/amhello-1.0 % make installcheck
+ ...
+
+ The user first unpacks the package. Here, and in the following
+examples, we will use the non-portable `tar zxf' command for
+simplicity. On a system without GNU `tar' installed, this command
+should read `gunzip -c amhello-1.0.tar.gz | tar xf -'.
+
+ The user then enters the newly created directory to run the
+`configure' script. This script probes the system for various
+features, and finally creates the `Makefile's. In this toy example
+there are only two `Makefile's, but in real-world projects, there may
+be many more, usually one `Makefile' per directory.
+
+ It is now possible to run `make'. This will construct all the
+programs, libraries, and scripts that need to be constructed for the
+package. In our example, this compiles the `hello' program. All files
+are constructed in place, in the source tree; we will see later how
+this can be changed.
+
+ `make check' causes the package's tests to be run. This step is not
+mandatory, but it is often good to make sure the programs that have
+been built behave as they should, before you decide to install them.
+Our example does not contain any tests, so running `make check' is a
+no-op.
+
+ After everything has been built, and maybe tested, it is time to
+install it on the system. That means copying the programs, libraries,
+header files, scripts, and other data files from the source directory
+to their final destination on the system. The command `make install'
+will do that. However, by default everything will be installed in
+subdirectories of `/usr/local': binaries will go into `/usr/local/bin',
+libraries will end up in `/usr/local/lib', etc. This destination is
+usually not writable by any user, so we assume that we have to become
+root before we can run `make install'. In our example, running `make
+install' will copy the program `hello' into `/usr/local/bin' and
+`README' into `/usr/local/share/doc/amhello'.
+
+ A last and optional step is to run `make installcheck'. This
+command may run tests on the installed files. `make check' tests the
+files in the source tree, while `make installcheck' tests their
+installed copies. The tests run by the latter can be different from
+those run by the former. For instance, there are tests that cannot be
+run in the source tree. Conversely, some packages are set up so that
+`make installcheck' will run the very same tests as `make check', only
+on different files (non-installed vs. installed). It can make a
+difference, for instance when the source tree's layout is different
+from that of the installation. Furthermore it may help to diagnose an
+incomplete installation.
+
+ Presently most packages do not have any `installcheck' tests because
+the existence of `installcheck' is little known, and its usefulness is
+neglected. Our little toy package is no better: `make installcheck'
+does nothing.
+
+\1f
+File: automake.info, Node: Standard Targets, Next: Standard Directory Variables, Prev: Basic Installation, Up: Use Cases
+
+2.2.2 Standard `Makefile' Targets
+---------------------------------
+
+So far we have come across four ways to run `make' in the GNU Build
+System: `make', `make check', `make install', and `make installcheck'.
+The words `check', `install', and `installcheck', passed as arguments
+to `make', are called "targets". `make' is a shorthand for `make all',
+`all' being the default target in the GNU Build System.
+
+ Here is a list of the most useful targets that the GNU Coding
+Standards specify.
+
+`make all'
+ Build programs, libraries, documentation, etc. (same as `make').
+
+`make install'
+ Install what needs to be installed, copying the files from the
+ package's tree to system-wide directories.
+
+`make install-strip'
+ Same as `make install', then strip debugging symbols. Some users
+ like to trade space for useful bug reports...
+
+`make uninstall'
+ The opposite of `make install': erase the installed files. (This
+ needs to be run from the same build tree that was installed.)
+
+`make clean'
+ Erase from the build tree the files built by `make all'.
+
+`make distclean'
+ Additionally erase anything `./configure' created.
+
+`make check'
+ Run the test suite, if any.
+
+`make installcheck'
+ Check the installed programs or libraries, if supported.
+
+`make dist'
+ Recreate `PACKAGE-VERSION.tar.gz' from all the source files.
+
+\1f
+File: automake.info, Node: Standard Directory Variables, Next: Standard Configuration Variables, Prev: Standard Targets, Up: Use Cases
+
+2.2.3 Standard Directory Variables
+----------------------------------
+
+The GNU Coding Standards also specify a hierarchy of variables to
+denote installation directories. Some of these are:
+
+Directory variable Default value
+-------------------------------------------------------
+`prefix' `/usr/local'
+ `exec_prefix' `${prefix}'
+ `bindir' `${exec_prefix}/bin'
+ `libdir' `${exec_prefix}/lib'
+ ...
+ `includedir' `${prefix}/include'
+ `datarootdir' `${prefix}/share'
+ `datadir' `${datarootdir}'
+ `mandir' `${datarootdir}/man'
+ `infodir' `${datarootdir}/info'
+ `docdir' `${datarootdir}/doc/${PACKAGE}'
+ ...
+
+ Each of these directories has a role which is often obvious from its
+name. In a package, any installable file will be installed in one of
+these directories. For instance in `amhello-1.0', the program `hello'
+is to be installed in BINDIR, the directory for binaries. The default
+value for this directory is `/usr/local/bin', but the user can supply a
+different value when calling `configure'. Also the file `README' will
+be installed into DOCDIR, which defaults to
+`/usr/local/share/doc/amhello'.
+
+ As a user, if you wish to install a package on your own account, you
+could proceed as follows:
+
+ ~/amhello-1.0 % ./configure --prefix ~/usr
+ ...
+ ~/amhello-1.0 % make
+ ...
+ ~/amhello-1.0 % make install
+ ...
+
+ This would install `~/usr/bin/hello' and
+`~/usr/share/doc/amhello/README'.
+
+ The list of all such directory options is shown by `./configure
+--help'.
+
+\1f
+File: automake.info, Node: Standard Configuration Variables, Next: config.site, Prev: Standard Directory Variables, Up: Use Cases
+
+2.2.4 Standard Configuration Variables
+--------------------------------------
+
+The GNU Coding Standards also define a set of standard configuration
+variables used during the build. Here are some:
+
+`CC'
+ C compiler command
+
+`CFLAGS'
+ C compiler flags
+
+`CXX'
+ C++ compiler command
+
+`CXXFLAGS'
+ C++ compiler flags
+
+`LDFLAGS'
+ linker flags
+
+`CPPFLAGS'
+ C/C++ preprocessor flags
+
+...
+
+ `configure' usually does a good job at setting appropriate values
+for these variables, but there are cases where you may want to override
+them. For instance you may have several versions of a compiler
+installed and would like to use another one, you may have header files
+installed outside the default search path of the compiler, or even
+libraries out of the way of the linker.
+
+ Here is how one would call `configure' to force it to use `gcc-3' as
+C compiler, use header files from `~/usr/include' when compiling, and
+libraries from `~/usr/lib' when linking.
+
+ ~/amhello-1.0 % ./configure --prefix ~/usr CC=gcc-3 \
+ CPPFLAGS=-I$HOME/usr/include LDFLAGS=-L$HOME/usr/lib
+
+ Again, a full list of these variables appears in the output of
+`./configure --help'.
+
+\1f
+File: automake.info, Node: config.site, Next: VPATH Builds, Prev: Standard Configuration Variables, Up: Use Cases
+
+2.2.5 Overriding Default Configuration Setting with `config.site'
+-----------------------------------------------------------------
+
+When installing several packages using the same setup, it can be
+convenient to create a file to capture common settings. If a file
+named `PREFIX/share/config.site' exists, `configure' will source it at
+the beginning of its execution.
+
+ Recall the command from the previous section:
+
+ ~/amhello-1.0 % ./configure --prefix ~/usr CC=gcc-3 \
+ CPPFLAGS=-I$HOME/usr/include LDFLAGS=-L$HOME/usr/lib
+
+ Assuming we are installing many package in `~/usr', and will always
+want to use these definitions of `CC', `CPPFLAGS', and `LDFLAGS', we
+can automate this by creating the following `~/usr/share/config.site'
+file:
+
+ test -z "$CC" && CC=gcc-3
+ test -z "$CPPFLAGS" && CPPFLAGS=-I$HOME/usr/include
+ test -z "$LDFLAGS" && LDFLAGS=-L$HOME/usr/lib
+
+ Now, any time a `configure' script is using the `~/usr' prefix, it
+will execute the above `config.site' and define these three variables.
+
+ ~/amhello-1.0 % ./configure --prefix ~/usr
+ configure: loading site script /home/adl/usr/share/config.site
+ ...
+
+ *Note Setting Site Defaults: (autoconf)Site Defaults, for more
+information about this feature.
+

+File: automake.info, Node: VPATH Builds, Next: Two-Part Install, Prev: config.site, Up: Use Cases
+
+2.2.6 Parallel Build Trees (a.k.a. VPATH Builds)
+------------------------------------------------
+
+The GNU Build System distinguishes two trees: the source tree, and the
+build tree.
+
+ The source tree is rooted in the directory containing `configure'.
+It contains all the sources files (those that are distributed), and may
+be arranged using several subdirectories.
+
+ The build tree is rooted in the directory in which `configure' was
+run, and is populated with all object files, programs, libraries, and
+other derived files built from the sources (and hence not distributed).
+The build tree usually has the same subdirectory layout as the source
+tree; its subdirectories are created automatically by the build system.
+
+ If `configure' is executed in its own directory, the source and
+build trees are combined: derived files are constructed in the same
+directories as their sources. This was the case in our first
+installation example (*note Basic Installation::).
+
+ A common request from users is that they want to confine all derived
+files to a single directory, to keep their source directories
+uncluttered. Here is how we could run `configure' to build everything
+in a subdirectory called `build/'.
+
+ ~ % tar zxf ~/amhello-1.0.tar.gz
+ ~ % cd amhello-1.0
+ ~/amhello-1.0 % mkdir build && cd build
+ ~/amhello-1.0/build % ../configure
+ ...
+ ~/amhello-1.0/build % make
+ ...
+
+ These setups, where source and build trees are different, are often
+called "parallel builds" or "VPATH builds". The expression _parallel
+build_ is misleading: the word _parallel_ is a reference to the way the
+build tree shadows the source tree, it is not about some concurrency in
+the way build commands are run. For this reason we refer to such
+setups using the name _VPATH builds_ in the following. _VPATH_ is the
+name of the `make' feature used by the `Makefile's to allow these
+builds (*note `VPATH' Search Path for All Prerequisites: (make)General
+Search.).
+
+ VPATH builds have other interesting uses. One is to build the same
+sources with multiple configurations. For instance:
+
+ ~ % tar zxf ~/amhello-1.0.tar.gz
+ ~ % cd amhello-1.0
+ ~/amhello-1.0 % mkdir debug optim && cd debug
+ ~/amhello-1.0/debug % ../configure CFLAGS='-g -O0'
+ ...
+ ~/amhello-1.0/debug % make
+ ...
+ ~/amhello-1.0/debug % cd ../optim
+ ~/amhello-1.0/optim % ../configure CFLAGS='-O3 -fomit-frame-pointer'
+ ...
+ ~/amhello-1.0/optim % make
+ ...
+
+ With network file systems, a similar approach can be used to build
+the same sources on different machines. For instance, suppose that the
+sources are installed on a directory shared by two hosts: `HOST1' and
+`HOST2', which may be different platforms.
+
+ ~ % cd /nfs/src
+ /nfs/src % tar zxf ~/amhello-1.0.tar.gz
+
+ On the first host, you could create a local build directory:
+ [HOST1] ~ % mkdir /tmp/amh && cd /tmp/amh
+ [HOST1] /tmp/amh % /nfs/src/amhello-1.0/configure
+ ...
+ [HOST1] /tmp/amh % make && sudo make install
+ ...
+
+(Here we assume that the installer has configured `sudo' so it can
+execute `make install' with root privileges; it is more convenient than
+using `su' like in *note Basic Installation::).
+
+ On the second host, you would do exactly the same, possibly at the
+same time:
+ [HOST2] ~ % mkdir /tmp/amh && cd /tmp/amh
+ [HOST2] /tmp/amh % /nfs/src/amhello-1.0/configure
+ ...
+ [HOST2] /tmp/amh % make && sudo make install
+ ...
+
+ In this scenario, nothing forbids the `/nfs/src/amhello-1.0'
+directory from being read-only. In fact VPATH builds are also a means
+of building packages from a read-only medium such as a CD-ROM. (The
+FSF used to sell CD-ROM with unpacked source code, before the GNU
+project grew so big.)
+
+\1f
+File: automake.info, Node: Two-Part Install, Next: Cross-Compilation, Prev: VPATH Builds, Up: Use Cases
+
+2.2.7 Two-Part Installation
+---------------------------
+
+In our last example (*note VPATH Builds::), a source tree was shared by
+two hosts, but compilation and installation were done separately on
+each host.
+
+ The GNU Build System also supports networked setups where part of the
+installed files should be shared amongst multiple hosts. It does so by
+distinguishing architecture-dependent files from
+architecture-independent files, and providing two `Makefile' targets to
+install each of these classes of files.
+
+ These targets are `install-exec' for architecture-dependent files
+and `install-data' for architecture-independent files. The command we
+used up to now, `make install', can be thought of as a shorthand for
+`make install-exec install-data'.
+
+ From the GNU Build System point of view, the distinction between
+architecture-dependent files and architecture-independent files is
+based exclusively on the directory variable used to specify their
+installation destination. In the list of directory variables we
+provided earlier (*note Standard Directory Variables::), all the
+variables based on EXEC-PREFIX designate architecture-dependent
+directories whose files will be installed by `make install-exec'. The
+others designate architecture-independent directories and will serve
+files installed by `make install-data'. *Note The Two Parts of
+Install::, for more details.
+
+ Here is how we could revisit our two-host installation example,
+assuming that (1) we want to install the package directly in `/usr',
+and (2) the directory `/usr/share' is shared by the two hosts.
+
+ On the first host we would run
+ [HOST1] ~ % mkdir /tmp/amh && cd /tmp/amh
+ [HOST1] /tmp/amh % /nfs/src/amhello-1.0/configure --prefix /usr
+ ...
+ [HOST1] /tmp/amh % make && sudo make install
+ ...
+
+ On the second host, however, we need only install the
+architecture-specific files.
+ [HOST2] ~ % mkdir /tmp/amh && cd /tmp/amh
+ [HOST2] /tmp/amh % /nfs/src/amhello-1.0/configure --prefix /usr
+ ...
+ [HOST2] /tmp/amh % make && sudo make install-exec
+ ...
+
+ In packages that have installation checks, it would make sense to run
+`make installcheck' (*note Basic Installation::) to verify that the
+package works correctly despite the apparent partial installation.
+
+\1f
+File: automake.info, Node: Cross-Compilation, Next: Renaming, Prev: Two-Part Install, Up: Use Cases
+
+2.2.8 Cross-Compilation
+-----------------------
+
+To "cross-compile" is to build on one platform a binary that will run
+on another platform. When speaking of cross-compilation, it is
+important to distinguish between the "build platform" on which the
+compilation is performed, and the "host platform" on which the
+resulting executable is expected to run. The following `configure'
+options are used to specify each of them:
+
+`--build=BUILD'
+ The system on which the package is built.
+
+`--host=HOST'
+ The system where built programs and libraries will run.
+
+ When the `--host' is used, `configure' will search for the
+cross-compiling suite for this platform. Cross-compilation tools
+commonly have their target architecture as prefix of their name. For
+instance my cross-compiler for MinGW32 has its binaries called
+`i586-mingw32msvc-gcc', `i586-mingw32msvc-ld', `i586-mingw32msvc-as',
+etc.
+
+ Here is how we could build `amhello-1.0' for `i586-mingw32msvc' on a
+GNU/Linux PC.
+
+ ~/amhello-1.0 % ./configure --build i686-pc-linux-gnu --host i586-mingw32msvc
+ checking for a BSD-compatible install... /usr/bin/install -c
+ checking whether build environment is sane... yes
+ checking for gawk... gawk
+ checking whether make sets $(MAKE)... yes
+ checking for i586-mingw32msvc-strip... i586-mingw32msvc-strip
+ checking for i586-mingw32msvc-gcc... i586-mingw32msvc-gcc
+ checking for C compiler default output file name... a.exe
+ checking whether the C compiler works... yes
+ checking whether we are cross compiling... yes
+ checking for suffix of executables... .exe
+ checking for suffix of object files... o
+ checking whether we are using the GNU C compiler... yes
+ checking whether i586-mingw32msvc-gcc accepts -g... yes
+ checking for i586-mingw32msvc-gcc option to accept ANSI C...
+ ...
+ ~/amhello-1.0 % make
+ ...
+ ~/amhello-1.0 % cd src; file hello.exe
+ hello.exe: MS Windows PE 32-bit Intel 80386 console executable not relocatable
+
+ The `--host' and `--build' options are usually all we need for
+cross-compiling. The only exception is if the package being built is
+itself a cross-compiler: we need a third option to specify its target
+architecture.
+
+`--target=TARGET'
+ When building compiler tools: the system for which the tools will
+ create output.
+
+ For instance when installing GCC, the GNU Compiler Collection, we can
+use `--target=TARGET' to specify that we want to build GCC as a
+cross-compiler for TARGET. Mixing `--build' and `--target', we can
+actually cross-compile a cross-compiler; such a three-way
+cross-compilation is known as a "Canadian cross".
+
+ *Note Specifying the System Type: (autoconf)Specifying Names, for
+more information about these `configure' options.

+File: automake.info, Node: Renaming, Next: DESTDIR, Prev: Cross-Compilation, Up: Use Cases
+
+2.2.9 Renaming Programs at Install Time
+---------------------------------------
+
+The GNU Build System provides means to automatically rename executables
+and manpages before they are installed (*note Man Pages::). This is
+especially convenient when installing a GNU package on a system that
+already has a proprietary implementation you do not want to overwrite.
+For instance, you may want to install GNU `tar' as `gtar' so you can
+distinguish it from your vendor's `tar'.
+
+ This can be done using one of these three `configure' options.
+
+`--program-prefix=PREFIX'
+ Prepend PREFIX to installed program names.
+
+`--program-suffix=SUFFIX'
+ Append SUFFIX to installed program names.
+
+`--program-transform-name=PROGRAM'
+ Run `sed PROGRAM' on installed program names.
+
+ The following commands would install `hello' as
+`/usr/local/bin/test-hello', for instance.
+
+ ~/amhello-1.0 % ./configure --program-prefix test-
+ ...
+ ~/amhello-1.0 % make
+ ...
+ ~/amhello-1.0 % sudo make install
+ ...
+
+\1f
+File: automake.info, Node: DESTDIR, Next: Preparing Distributions, Prev: Renaming, Up: Use Cases
+
+2.2.10 Building Binary Packages Using DESTDIR
+---------------------------------------------
+
+The GNU Build System's `make install' and `make uninstall' interface
+does not exactly fit the needs of a system administrator who has to
+deploy and upgrade packages on lots of hosts. In other words, the GNU
+Build System does not replace a package manager.
+
+ Such package managers usually need to know which files have been
+installed by a package, so a mere `make install' is inappropriate.
+
+ The `DESTDIR' variable can be used to perform a staged installation.
+The package should be configured as if it was going to be installed in
+its final location (e.g., `--prefix /usr'), but when running `make
+install', the `DESTDIR' should be set to the absolute name of a
+directory into which the installation will be diverted. From this
+directory it is easy to review which files are being installed where,
+and finally copy them to their final location by some means.
+
+ For instance here is how we could create a binary package containing
+a snapshot of all the files to be installed.
+
+ ~/amhello-1.0 % ./configure --prefix /usr
+ ...
+ ~/amhello-1.0 % make
+ ...
+ ~/amhello-1.0 % make DESTDIR=$HOME/inst install
+ ...
+ ~/amhello-1.0 % cd ~/inst
+ ~/inst % find . -type f -print > ../files.lst
+ ~/inst % tar zcvf ~/amhello-1.0-i686.tar.gz `cat ../files.lst`
+ ./usr/bin/hello
+ ./usr/share/doc/amhello/README
+
+ After this example, `amhello-1.0-i686.tar.gz' is ready to be
+uncompressed in `/' on many hosts. (Using ``cat ../files.lst`' instead
+of `.' as argument for `tar' avoids entries for each subdirectory in
+the archive: we would not like `tar' to restore the modification time
+of `/', `/usr/', etc.)
+
+ Note that when building packages for several architectures, it might
+be convenient to use `make install-data' and `make install-exec' (*note
+Two-Part Install::) to gather architecture-independent files in a
+single package.
+
+ *Note Install::, for more information.

+
+2.2.11 Preparing Distributions
+------------------------------
+
+We have already mentioned `make dist'. This target collects all your
+source files and the necessary parts of the build system to create a
+tarball named `PACKAGE-VERSION.tar.gz'.
+
+ Another, more useful command is `make distcheck'. The `distcheck'
+target constructs `PACKAGE-VERSION.tar.gz' just as well as `dist', but
+it additionally ensures most of the use cases presented so far work:
+
+ * It attempts a full compilation of the package (*note Basic
+ Installation::), unpacking the newly constructed tarball, running
+ `make', `make check', `make install', as well as `make
+ installcheck', and even `make dist',
+
+ * it tests VPATH builds with read-only source tree (*note VPATH
+ Builds::),
+
+ * it makes sure `make clean', `make distclean', and `make uninstall'
+ do not omit any file (*note Standard Targets::),
+
+ * and it checks that `DESTDIR' installations work (*note DESTDIR::).
+
+ All of these actions are performed in a temporary subdirectory, so
+that no root privileges are required.
+
+ Releasing a package that fails `make distcheck' means that one of
+the scenarios we presented will not work and some users will be
+disappointed. Therefore it is a good practice to release a package
+only after a successful `make distcheck'. This of course does not
+imply that the package will be flawless, but at least it will prevent
+some of the embarrassing errors you may find in packages released by
+people who have never heard about `distcheck' (like `DESTDIR' not
+working because of a typo, or a distributed file being erased by `make
+clean', or even `VPATH' builds not working).

+File: automake.info, Node: Dependency Tracking, Next: Nested Packages, Prev: Preparing Distributions, Up: Use Cases
+
+2.2.12 Automatic Dependency Tracking
+------------------------------------
+
+Dependency tracking is performed as a side-effect of compilation. Each
+time the build system compiles a source file, it computes its list of
+dependencies (in C these are the header files included by the source
+being compiled). Later, any time `make' is run and a dependency
+appears to have changed, the dependent files will be rebuilt.
+
+ Automake generates code for automatic dependency tracking by default,
+unless the developer chooses to override it; for more information,
+*note Dependencies::.
+
+ When `configure' is executed, you can see it probing each compiler
+for the dependency mechanism it supports (several mechanisms can be
+used):
+
+ ~/amhello-1.0 % ./configure --prefix /usr
+ ...
+ checking dependency style of gcc... gcc3
+ ...
+
+ Because dependencies are only computed as a side-effect of the
+compilation, no dependency information exists the first time a package
+is built. This is OK because all the files need to be built anyway:
+`make' does not have to decide which files need to be rebuilt. In
+fact, dependency tracking is completely useless for one-time builds and
+there is a `configure' option to disable this:
+
+`--disable-dependency-tracking'
+ Speed up one-time builds.
+
+ Some compilers do not offer any practical way to derive the list of
+dependencies as a side-effect of the compilation, requiring a separate
+run (maybe of another tool) to compute these dependencies. The
+performance penalty implied by these methods is important enough to
+disable them by default. The option `--enable-dependency-tracking'
+must be passed to `configure' to activate them.
+
+`--enable-dependency-tracking'
+ Do not reject slow dependency extractors.
+
+ *Note Dependency Tracking Evolution: (automake-history)Dependency
+Tracking Evolution, for some discussion about the different dependency
+tracking schemes used by Automake over the years.

+
+2.2.13 Nested Packages
+----------------------
+
+Although nesting packages isn't something we would recommend to someone
+who is discovering the Autotools, it is a nice feature worthy of
+mention in this small advertising tour.
+
+ Autoconfiscated packages (that means packages whose build system have
+been created by Autoconf and friends) can be nested to arbitrary depth.
+
+ A typical setup is that package A will distribute one of the
+libraries it needs in a subdirectory. This library B is a complete
+package with its own GNU Build System. The `configure' script of A will
+run the `configure' script of B as part of its execution, building and
+installing A will also build and install B. Generating a distribution
+for A will also include B.
+
+ It is possible to gather several packages like this. GCC is a heavy
+user of this feature. This gives installers a single package to
+configure, build and install, while it allows developers to work on
+subpackages independently.
+
+ When configuring nested packages, the `configure' options given to
+the top-level `configure' are passed recursively to nested
+`configure's. A package that does not understand an option will ignore
+it, assuming it is meaningful to some other package.
+
+ The command `configure --help=recursive' can be used to display the
+options supported by all the included packages.
+
+ *Note Subpackages::, for an example setup.

+
+2.3 How Autotools Help
+======================
+
+There are several reasons why you may not want to implement the GNU
+Build System yourself (read: write a `configure' script and `Makefile's
+yourself).
+
+ * As we have seen, the GNU Build System has a lot of features (*note
+ Use Cases::). Some users may expect features you have not
+ implemented because you did not need them.
+
+ * Implementing these features portably is difficult and exhausting.
+ Think of writing portable shell scripts, and portable `Makefile's,
+ for systems you may not have handy. *Note Portable Shell
+ Programming: (autoconf)Portable Shell, to convince yourself.
+
+ * You will have to upgrade your setup to follow changes to the GNU
+ Coding Standards.
+
+ The GNU Autotools take all this burden off your back and provide:
+
+ * Tools to create a portable, complete, and self-contained GNU Build
+ System, from simple instructions. _Self-contained_ meaning the
+ resulting build system does not require the GNU Autotools.
+
+ * A central place where fixes and improvements are made: a bug-fix
+ for a portability issue will benefit every package.
+
+ Yet there also exist reasons why you may want NOT to use the
+Autotools... For instance you may be already using (or used to) another
+incompatible build system. Autotools will only be useful if you do
+accept the concepts of the GNU Build System. People who have their own
+idea of how a build system should work will feel frustrated by the
+Autotools.

+
+2.4.1 Creating `amhello-1.0.tar.gz'
+-----------------------------------
+
+Here is how we can recreate `amhello-1.0.tar.gz' from scratch. The
+package is simple enough so that we will only need to write 5 files.
+(You may copy them from the final `amhello-1.0.tar.gz' that is
+distributed with Automake if you do not want to write them.)
+
+ Create the following files in an empty directory.
+
+ * `src/main.c' is the source file for the `hello' program. We store
+ it in the `src/' subdirectory, because later, when the package
+ evolves, it will ease the addition of a `man/' directory for man
+ pages, a `data/' directory for data files, etc.
+ ~/amhello % cat src/main.c
+ #include <config.h>
+ #include <stdio.h>
+
+ int
+ main (void)
+ {
+ puts ("Hello World!");
+ puts ("This is " PACKAGE_STRING ".");
+ return 0;
+ }
+
+ * `README' contains some very limited documentation for our little
+ package.
+ ~/amhello % cat README
+ This is a demonstration package for GNU Automake.
+ Type `info Automake' to read the Automake manual.
+
+ * `Makefile.am' and `src/Makefile.am' contain Automake instructions
+ for these two directories.
+
+ ~/amhello % cat src/Makefile.am
+ bin_PROGRAMS = hello
+ hello_SOURCES = main.c
+ ~/amhello % cat Makefile.am
+ SUBDIRS = src
+ dist_doc_DATA = README
+
+ * Finally, `configure.ac' contains Autoconf instructions to create
+ the `configure' script.
+
+ ~/amhello % cat configure.ac
+ AC_INIT([amhello], [1.0], [bug-automake@gnu.org])
+ AM_INIT_AUTOMAKE([-Wall -Werror foreign])
+ AC_PROG_CC
+ AC_CONFIG_HEADERS([config.h])
+ AC_CONFIG_FILES([
+ Makefile
+ src/Makefile
+ ])
+ AC_OUTPUT
+
+ Once you have these five files, it is time to run the Autotools to
+instantiate the build system. Do this using the `autoreconf' command
+as follows:
+
+ ~/amhello % autoreconf --install
+ configure.ac: installing `./install-sh'
+ configure.ac: installing `./missing'
+ src/Makefile.am: installing `./depcomp'
+
+ At this point the build system is complete.
+
+ In addition to the three scripts mentioned in its output, you can see
+that `autoreconf' created four other files: `configure', `config.h.in',
+`Makefile.in', and `src/Makefile.in'. The latter three files are
+templates that will be adapted to the system by `configure' under the
+names `config.h', `Makefile', and `src/Makefile'. Let's do this:
+
+ ~/amhello % ./configure
+ checking for a BSD-compatible install... /usr/bin/install -c
+ checking whether build environment is sane... yes
+ checking for gawk... no
+ checking for mawk... mawk
+ checking whether make sets $(MAKE)... yes
+ checking for gcc... gcc
+ checking for C compiler default output file name... a.out
+ checking whether the C compiler works... yes
+ checking whether we are cross compiling... no
+ checking for suffix of executables...
+ checking for suffix of object files... o
+ checking whether we are using the GNU C compiler... yes
+ checking whether gcc accepts -g... yes
+ checking for gcc option to accept ISO C89... none needed
+ checking for style of include used by make... GNU
+ checking dependency style of gcc... gcc3
+ configure: creating ./config.status
+ config.status: creating Makefile
+ config.status: creating src/Makefile
+ config.status: creating config.h
+ config.status: executing depfiles commands
+
+ You can see `Makefile', `src/Makefile', and `config.h' being created
+at the end after `configure' has probed the system. It is now possible
+to run all the targets we wish (*note Standard Targets::). For
+instance:
+
+ ~/amhello % make
+ ...
+ ~/amhello % src/hello
+ Hello World!
+ This is amhello 1.0.
+ ~/amhello % make distcheck
+ ...
+ =============================================
+ amhello-1.0 archives ready for distribution:
+ amhello-1.0.tar.gz
+ =============================================
+
+ Note that running `autoreconf' is only needed initially when the GNU
+Build System does not exist. When you later change some instructions
+in a `Makefile.am' or `configure.ac', the relevant part of the build
+system will be regenerated automatically when you execute `make'.
+
+ `autoreconf' is a script that calls `autoconf', `automake', and a
+bunch of other commands in the right order. If you are beginning with
+these tools, it is not important to figure out in which order all these
+tools should be invoked and why. However, because Autoconf and
+Automake have separate manuals, the important point to understand is
+that `autoconf' is in charge of creating `configure' from
+`configure.ac', while `automake' is in charge of creating
+`Makefile.in's from `Makefile.am's and `configure.ac'. This should at
+least direct you to the right manual when seeking answers.

+
+2.4.2 `amhello''s `configure.ac' Setup Explained
+------------------------------------------------
+
+Let us begin with the contents of `configure.ac'.
+
+ AC_INIT([amhello], [1.0], [bug-automake@gnu.org])
+ AM_INIT_AUTOMAKE([-Wall -Werror foreign])
+ AC_PROG_CC
+ AC_CONFIG_HEADERS([config.h])
+ AC_CONFIG_FILES([
+ Makefile
+ src/Makefile
+ ])
+ AC_OUTPUT
+
+ This file is read by both `autoconf' (to create `configure') and
+`automake' (to create the various `Makefile.in's). It contains a
+series of M4 macros that will be expanded as shell code to finally form
+the `configure' script. We will not elaborate on the syntax of this
+file, because the Autoconf manual has a whole section about it (*note
+Writing `configure.ac': (autoconf)Writing Autoconf Input.).
+
+ The macros prefixed with `AC_' are Autoconf macros, documented in
+the Autoconf manual (*note Autoconf Macro Index: (autoconf)Autoconf
+Macro Index.). The macros that start with `AM_' are Automake macros,
+documented later in this manual (*note Macro Index::).
+
+ The first two lines of `configure.ac' initialize Autoconf and
+Automake. `AC_INIT' takes in as parameters the name of the package,
+its version number, and a contact address for bug-reports about the
+package (this address is output at the end of `./configure --help', for
+instance). When adapting this setup to your own package, by all means
+please do not blindly copy Automake's address: use the mailing list of
+your package, or your own mail address.
+
+ The argument to `AM_INIT_AUTOMAKE' is a list of options for
+`automake' (*note Options::). `-Wall' and `-Werror' ask `automake' to
+turn on all warnings and report them as errors. We are speaking of
+*Automake* warnings here, such as dubious instructions in
+`Makefile.am'. This has absolutely nothing to do with how the compiler
+will be called, even though it may support options with similar names.
+Using `-Wall -Werror' is a safe setting when starting to work on a
+package: you do not want to miss any issues. Later you may decide to
+relax things a bit. The `foreign' option tells Automake that this
+package will not follow the GNU Standards. GNU packages should always
+distribute additional files such as `ChangeLog', `AUTHORS', etc. We do
+not want `automake' to complain about these missing files in our small
+example.
+
+ The `AC_PROG_CC' line causes the `configure' script to search for a
+C compiler and define the variable `CC' with its name. The
+`src/Makefile.in' file generated by Automake uses the variable `CC' to
+build `hello', so when `configure' creates `src/Makefile' from
+`src/Makefile.in', it will define `CC' with the value it has found. If
+Automake is asked to create a `Makefile.in' that uses `CC' but
+`configure.ac' does not define it, it will suggest you add a call to
+`AC_PROG_CC'.
+
+ The `AC_CONFIG_HEADERS([config.h])' invocation causes the
+`configure' script to create a `config.h' file gathering `#define's
+defined by other macros in `configure.ac'. In our case, the `AC_INIT'
+macro already defined a few of them. Here is an excerpt of `config.h'
+after `configure' has run:
+
+ ...
+ /* Define to the address where bug reports for this package should be sent. */
+ #define PACKAGE_BUGREPORT "bug-automake@gnu.org"
+
+ /* Define to the full name and version of this package. */
+ #define PACKAGE_STRING "amhello 1.0"
+ ...
+
+ As you probably noticed, `src/main.c' includes `config.h' so it can
+use `PACKAGE_STRING'. In a real-world project, `config.h' can grow
+really big, with one `#define' per feature probed on the system.
+
+ The `AC_CONFIG_FILES' macro declares the list of files that
+`configure' should create from their `*.in' templates. Automake also
+scans this list to find the `Makefile.am' files it must process. (This
+is important to remember: when adding a new directory to your project,
+you should add its `Makefile' to this list, otherwise Automake will
+never process the new `Makefile.am' you wrote in that directory.)
+
+ Finally, the `AC_OUTPUT' line is a closing command that actually
+produces the part of the script in charge of creating the files
+registered with `AC_CONFIG_HEADERS' and `AC_CONFIG_FILES'.
+
+ When starting a new project, we suggest you start with such a simple
+`configure.ac', and gradually add the other tests it requires. The
+command `autoscan' can also suggest a few of the tests your package may
+need (*note Using `autoscan' to Create `configure.ac':
+(autoconf)autoscan Invocation.).

+
+2.4.3 `amhello''s `Makefile.am' Setup Explained
+-----------------------------------------------
+
+We now turn to `src/Makefile.am'. This file contains Automake
+instructions to build and install `hello'.
+
+ bin_PROGRAMS = hello
+ hello_SOURCES = main.c
+
+ A `Makefile.am' has the same syntax as an ordinary `Makefile'. When
+`automake' processes a `Makefile.am' it copies the entire file into the
+output `Makefile.in' (that will be later turned into `Makefile' by
+`configure') but will react to certain variable definitions by
+generating some build rules and other variables. Often `Makefile.am's
+contain only a list of variable definitions as above, but they can also
+contain other variable and rule definitions that `automake' will pass
+along without interpretation.
+
+ Variables that end with `_PROGRAMS' are special variables that list
+programs that the resulting `Makefile' should build. In Automake
+speak, this `_PROGRAMS' suffix is called a "primary"; Automake
+recognizes other primaries such as `_SCRIPTS', `_DATA', `_LIBRARIES',
+etc. corresponding to different types of files.
+
+ The `bin' part of the `bin_PROGRAMS' tells `automake' that the
+resulting programs should be installed in BINDIR. Recall that the GNU
+Build System uses a set of variables to denote destination directories
+and allow users to customize these locations (*note Standard Directory
+Variables::). Any such directory variable can be put in front of a
+primary (omitting the `dir' suffix) to tell `automake' where to install
+the listed files.
+
+ Programs need to be built from source files, so for each program
+`PROG' listed in a `_PROGRAMS' variable, `automake' will look for
+another variable named `PROG_SOURCES' listing its source files. There
+may be more than one source file: they will all be compiled and linked
+together.
+
+ Automake also knows that source files need to be distributed when
+creating a tarball (unlike built programs). So a side-effect of this
+`hello_SOURCES' declaration is that `main.c' will be part of the
+tarball created by `make dist'.
+
+ Finally here are some explanations regarding the top-level
+`Makefile.am'.
+
+ SUBDIRS = src
+ dist_doc_DATA = README
+
+ `SUBDIRS' is a special variable listing all directories that `make'
+should recurse into before processing the current directory. So this
+line is responsible for `make' building `src/hello' even though we run
+it from the top-level. This line also causes `make install' to install
+`src/hello' before installing `README' (not that this order matters).
+
+ The line `dist_doc_DATA = README' causes `README' to be distributed
+and installed in DOCDIR. Files listed with the `_DATA' primary are not
+automatically part of the tarball built with `make dist', so we add the
+`dist_' prefix so they get distributed. However, for `README' it would
+not have been necessary: `automake' automatically distributes any
+`README' file it encounters (the list of other files automatically
+distributed is presented by `automake --help'). The only important
+effect of this second line is therefore to install `README' during
+`make install'.
+
+ One thing not covered in this example is accessing the installation
+directory values (*note Standard Directory Variables::) from your
+program code, that is, converting them into defined macros. For this,
+*note Defining Directories: (autoconf)Defining Directories.

+\1f
+File: automake.info, Node: General Operation, Next: Strictness, Up: Generalities
+
+3.1 General Operation
+=====================
+
+Automake works by reading a `Makefile.am' and generating a
+`Makefile.in'. Certain variables and rules defined in the
+`Makefile.am' instruct Automake to generate more specialized code; for
+instance, a `bin_PROGRAMS' variable definition will cause rules for
+compiling and linking programs to be generated.
+
+ The variable definitions and rules in the `Makefile.am' are copied
+mostly verbatim into the generated file, with all variable definitions
+preceding all rules. This allows you to add almost arbitrary code into
+the generated `Makefile.in'. For instance, the Automake distribution
+includes a non-standard rule for the `git-dist' target, which the
+Automake maintainer uses to make distributions from the source control
+system.
+
+ Note that most GNU make extensions are not recognized by Automake.
+Using such extensions in a `Makefile.am' will lead to errors or
+confusing behavior.
+
+ A special exception is that the GNU make append operator, `+=', is
+supported. This operator appends its right hand argument to the
+variable specified on the left. Automake will translate the operator
+into an ordinary `=' operator; `+=' will thus work with any make
+program.
+
+ Automake tries to keep comments grouped with any adjoining rules or
+variable definitions.
+
+ Generally, Automake is not particularly smart in the parsing of
+unusual Makefile constructs, so you're advised to avoid fancy
+constructs or "creative" use of whitespaces. For example, <TAB>
+characters cannot be used between a target name and the following "`:'"
+character, and variable assignments shouldn't be indented with <TAB>
+characters. Also, using more complex macro in target names can cause
+trouble:
+
+ % cat Makefile.am
+ $(FOO:=x): bar
+ % automake
+ Makefile.am:1: bad characters in variable name `$(FOO'
+ Makefile.am:1: `:='-style assignments are not portable
+
+ A rule defined in `Makefile.am' generally overrides any such rule of
+a similar name that would be automatically generated by `automake'.
+Although this is a supported feature, it is generally best to avoid
+making use of it, as sometimes the generated rules are very particular.
+
+ Similarly, a variable defined in `Makefile.am' or `AC_SUBST'ed from
+`configure.ac' will override any definition of the variable that
+`automake' would ordinarily create. This feature is more often useful
+than the ability to override a rule. Be warned that many of the
+variables generated by `automake' are considered to be for internal use
+only, and their names might change in future releases.
+
+ When examining a variable definition, Automake will recursively
+examine variables referenced in the definition. For example, if
+Automake is looking at the content of `foo_SOURCES' in this snippet
+
+ xs = a.c b.c
+ foo_SOURCES = c.c $(xs)
+
+ it would use the files `a.c', `b.c', and `c.c' as the contents of
+`foo_SOURCES'.
+
+ Automake also allows a form of comment that is _not_ copied into the
+output; all lines beginning with `##' (leading spaces allowed) are
+completely ignored by Automake.
+
+ It is customary to make the first line of `Makefile.am' read:
+
+ ## Process this file with automake to produce Makefile.in
+
+\1f
+File: automake.info, Node: Strictness, Next: Uniform, Prev: General Operation, Up: Generalities
+
+3.2 Strictness
+==============
+
+While Automake is intended to be used by maintainers of GNU packages, it
+does make some effort to accommodate those who wish to use it, but do
+not want to use all the GNU conventions.
+
+ To this end, Automake supports three levels of "strictness"--the
+strictness indicating how stringently Automake should check standards
+conformance.
+
+ The valid strictness levels are:
+
+`foreign'
+ Automake will check for only those things that are absolutely
+ required for proper operations. For instance, whereas GNU
+ standards dictate the existence of a `NEWS' file, it will not be
+ required in this mode. This strictness will also turn off some
+ warnings by default (among them, portability warnings). The name
+ comes from the fact that Automake is intended to be used for GNU
+ programs; these relaxed rules are not the standard mode of
+ operation.
+
+`gnu'
+ Automake will check--as much as possible--for compliance to the GNU
+ standards for packages. This is the default.
+
+`gnits'
+ Automake will check for compliance to the as-yet-unwritten "Gnits
+ standards". These are based on the GNU standards, but are even
+ more detailed. Unless you are a Gnits standards contributor, it is
+ recommended that you avoid this option until such time as the Gnits
+ standard is actually published (which may never happen).
+
+ *Note Gnits::, for more information on the precise implications of
+the strictness level.
+
+ Automake also has a special (and _today deprecated_) "cygnus" mode
+that is similar to strictness but handled differently. This mode is
+useful for packages that are put into a "Cygnus" style tree (e.g., older
+versions of the GCC and gdb trees). *Note Cygnus::, for more
+information on this mode. Please note that this mode _is deprecated
+and will be removed in the next major Automake release (1.13)_; you
+must avoid its use in new packages, and should stop using it in
+existing packages as well.
+

+
+3.3 The Uniform Naming Scheme
+=============================
+
+Automake variables generally follow a "uniform naming scheme" that
+makes it easy to decide how programs (and other derived objects) are
+built, and how they are installed. This scheme also supports
+`configure' time determination of what should be built.
+
+ At `make' time, certain variables are used to determine which
+objects are to be built. The variable names are made of several pieces
+that are concatenated together.
+
+ The piece that tells `automake' what is being built is commonly
+called the "primary". For instance, the primary `PROGRAMS' holds a
+list of programs that are to be compiled and linked.
+
+ A different set of names is used to decide where the built objects
+should be installed. These names are prefixes to the primary, and they
+indicate which standard directory should be used as the installation
+directory. The standard directory names are given in the GNU standards
+(*note Directory Variables: (standards)Directory Variables.). Automake
+extends this list with `pkgdatadir', `pkgincludedir', `pkglibdir', and
+`pkglibexecdir'; these are the same as the non-`pkg' versions, but with
+`$(PACKAGE)' appended. For instance, `pkglibdir' is defined as
+`$(libdir)/$(PACKAGE)'.
+
+ For each primary, there is one additional variable named by
+prepending `EXTRA_' to the primary name. This variable is used to list
+objects that may or may not be built, depending on what `configure'
+decides. This variable is required because Automake must statically
+know the entire list of objects that may be built in order to generate
+a `Makefile.in' that will work in all cases.
+
+ For instance, `cpio' decides at configure time which programs should
+be built. Some of the programs are installed in `bindir', and some are
+installed in `sbindir':
+
+ EXTRA_PROGRAMS = mt rmt
+ bin_PROGRAMS = cpio pax
+ sbin_PROGRAMS = $(MORE_PROGRAMS)
+
+ Defining a primary without a prefix as a variable, e.g., `PROGRAMS',
+is an error.
+
+ Note that the common `dir' suffix is left off when constructing the
+variable names; thus one writes `bin_PROGRAMS' and not
+`bindir_PROGRAMS'.
+
+ Not every sort of object can be installed in every directory.
+Automake will flag those attempts it finds in error (but see below how
+to override the check if you really need to). Automake will also
+diagnose obvious misspellings in directory names.
+
+ Sometimes the standard directories--even as augmented by
+Automake--are not enough. In particular it is sometimes useful, for
+clarity, to install objects in a subdirectory of some predefined
+directory. To this end, Automake allows you to extend the list of
+possible installation directories. A given prefix (e.g., `zar') is
+valid if a variable of the same name with `dir' appended is defined
+(e.g., `zardir').
+
+ For instance, the following snippet will install `file.xml' into
+`$(datadir)/xml'.
+
+ xmldir = $(datadir)/xml
+ xml_DATA = file.xml
+
+ This feature can also be used to override the sanity checks Automake
+performs to diagnose suspicious directory/primary couples (in the
+unlikely case these checks are undesirable, and you really know what
+you're doing). For example, Automake would error out on this input:
+
+ # Forbidden directory combinations, automake will error out on this.
+ pkglib_PROGRAMS = foo
+ doc_LIBRARIES = libquux.a
+
+but it will succeed with this:
+
+ # Work around forbidden directory combinations. Do not use this
+ # without a very good reason!
+ my_execbindir = $(pkglibdir)
+ my_doclibdir = $(docdir)
+ my_execbin_PROGRAMS = foo
+ my_doclib_LIBRARIES = libquux.a
+
+ The `exec' substring of the `my_execbindir' variable lets the files
+be installed at the right time (*note The Two Parts of Install::).
+
+ The special prefix `noinst_' indicates that the objects in question
+should be built but not installed at all. This is usually used for
+objects required to build the rest of your package, for instance static
+libraries (*note A Library::), or helper scripts.
+
+ The special prefix `check_' indicates that the objects in question
+should not be built until the `make check' command is run. Those
+objects are not installed either.
+
+ The current primary names are `PROGRAMS', `LIBRARIES',
+`LTLIBRARIES', `LISP', `PYTHON', `JAVA', `SCRIPTS', `DATA', `HEADERS',
+`MANS', and `TEXINFOS'.
+
+ Some primaries also allow additional prefixes that control other
+aspects of `automake''s behavior. The currently defined prefixes are
+`dist_', `nodist_', `nobase_', and `notrans_'. These prefixes are
+explained later (*note Program and Library Variables::) (*note Man
+Pages::).

+
+3.4 Staying below the command line length limit
+===============================================
+
+Traditionally, most unix-like systems have a length limitation for the
+command line arguments and environment contents when creating new
+processes (see for example
+`http://www.in-ulm.de/~mascheck/various/argmax/' for an overview on
+this issue), which of course also applies to commands spawned by `make'.
+POSIX requires this limit to be at least 4096 bytes, and most modern
+systems have quite high limits (or are unlimited).
+
+ In order to create portable Makefiles that do not trip over these
+limits, it is necessary to keep the length of file lists bounded.
+Unfortunately, it is not possible to do so fully transparently within
+Automake, so your help may be needed. Typically, you can split long
+file lists manually and use different installation directory names for
+each list. For example,
+
+ data_DATA = file1 ... fileN fileN+1 ... file2N
+
+may also be written as
+
+ data_DATA = file1 ... fileN
+ data2dir = $(datadir)
+ data2_DATA = fileN+1 ... file2N
+
+and will cause Automake to treat the two lists separately during `make
+install'. See *note The Two Parts of Install:: for choosing directory
+names that will keep the ordering of the two parts of installation Note
+that `make dist' may still only work on a host with a higher length
+limit in this example.
+
+ Automake itself employs a couple of strategies to avoid long command
+lines. For example, when `${srcdir}/' is prepended to file names, as
+can happen with above `$(data_DATA)' lists, it limits the amount of
+arguments passed to external commands.
+
+ Unfortunately, some system's `make' commands may prepend `VPATH'
+prefixes like `${srcdir}/' to file names from the source tree
+automatically (*note Automatic Rule Rewriting: (autoconf)Automatic Rule
+Rewriting.). In this case, the user may have to switch to use GNU
+Make, or refrain from using VPATH builds, in order to stay below the
+length limit.
+
+ For libraries and programs built from many sources, convenience
+archives may be used as intermediates in order to limit the object list
+length (*note Libtool Convenience Libraries::).
+
+\1f
+File: automake.info, Node: Canonicalization, Next: User Variables, Prev: Length Limitations, Up: Generalities
+
+3.5 How derived variables are named
+===================================
+
+Sometimes a Makefile variable name is derived from some text the
+maintainer supplies. For instance, a program name listed in
+`_PROGRAMS' is rewritten into the name of a `_SOURCES' variable. In
+cases like this, Automake canonicalizes the text, so that program names
+and the like do not have to follow Makefile variable naming rules. All
+characters in the name except for letters, numbers, the strudel (@),
+and the underscore are turned into underscores when making variable
+references.
+
+ For example, if your program is named `sniff-glue', the derived
+variable name would be `sniff_glue_SOURCES', not `sniff-glue_SOURCES'.
+Similarly the sources for a library named `libmumble++.a' should be
+listed in the `libmumble___a_SOURCES' variable.
+
+ The strudel is an addition, to make the use of Autoconf
+substitutions in variable names less obfuscating.
+
+\1f
+File: automake.info, Node: User Variables, Next: Auxiliary Programs, Prev: Canonicalization, Up: Generalities
+
+3.6 Variables reserved for the user
+===================================
+
+Some `Makefile' variables are reserved by the GNU Coding Standards for
+the use of the "user"--the person building the package. For instance,
+`CFLAGS' is one such variable.
+
+ Sometimes package developers are tempted to set user variables such
+as `CFLAGS' because it appears to make their job easier. However, the
+package itself should never set a user variable, particularly not to
+include switches that are required for proper compilation of the
+package. Since these variables are documented as being for the package
+builder, that person rightfully expects to be able to override any of
+these variables at build time.
+
+ To get around this problem, Automake introduces an automake-specific
+shadow variable for each user flag variable. (Shadow variables are not
+introduced for variables like `CC', where they would make no sense.)
+The shadow variable is named by prepending `AM_' to the user variable's
+name. For instance, the shadow variable for `YFLAGS' is `AM_YFLAGS'.
+The package maintainer--that is, the author(s) of the `Makefile.am' and
+`configure.ac' files--may adjust these shadow variables however
+necessary.
+
+ *Note Flag Variables Ordering::, for more discussion about these
+variables and how they interact with per-target variables.

+File: automake.info, Node: Auxiliary Programs, Prev: User Variables, Up: Generalities
+
+3.7 Programs automake might require
+===================================
+
+Automake sometimes requires helper programs so that the generated
+`Makefile' can do its work properly. There are a fairly large number
+of them, and we list them here.
+
+ Although all of these files are distributed and installed with
+Automake, a couple of them are maintained separately. The Automake
+copies are updated before each release, but we mention the original
+source in case you need more recent versions.
+
+`ar-lib'
+ This is a wrapper primarily for the Microsoft lib archiver, to make
+ it more POSIX-like.
+
+`compile'
+ This is a wrapper for compilers that do not accept options `-c'
+ and `-o' at the same time. It is only used when absolutely
+ required. Such compilers are rare, with the Microsoft C/C++
+ Compiler as the most notable exception. This wrapper also makes
+ the following common options available for that compiler, while
+ performing file name translation where needed: `-I', `-L', `-l',
+ `-Wl,' and `-Xlinker'.
+
+`config.guess'
+`config.sub'
+ These two programs compute the canonical triplets for the given
+ build, host, or target architecture. These programs are updated
+ regularly to support new architectures and fix probes broken by
+ changes in new kernel versions. Each new release of Automake
+ comes with up-to-date copies of these programs. If your copy of
+ Automake is getting old, you are encouraged to fetch the latest
+ versions of these files from
+ `http://savannah.gnu.org/git/?group=config' before making a
+ release.
+
+`depcomp'
+ This program understands how to run a compiler so that it will
+ generate not only the desired output but also dependency
+ information that is then used by the automatic dependency tracking
+ feature (*note Dependencies::).
+
+`elisp-comp'
+ This program is used to byte-compile Emacs Lisp code.
+
+`install-sh'
+ This is a replacement for the `install' program that works on
+ platforms where `install' is unavailable or unusable.
+
+`mdate-sh'
+ This script is used to generate a `version.texi' file. It examines
+ a file and prints some date information about it.
+
+`missing'
+ This wraps a number of programs that are typically only required by
+ maintainers. If the program in question doesn't exist, `missing'
+ prints an informative warning and attempts to fix things so that
+ the build can continue.
+
+`mkinstalldirs'
+ This script used to be a wrapper around `mkdir -p', which is not
+ portable. Now we prefer to use `install-sh -d' when `configure'
+ finds that `mkdir -p' does not work, this makes one less script to
+ distribute.
+
+ For backward compatibility `mkinstalldirs' is still used and
+ distributed when `automake' finds it in a package. But it is no
+ longer installed automatically, and it should be safe to remove it.
+
+`py-compile'
+ This is used to byte-compile Python scripts.
+
+`test-driver'
+ This implements the default test driver offered by the parallel
+ testsuite harness.
+
+`texinfo.tex'
+ Not a program, this file is required for `make dvi', `make ps' and
+ `make pdf' to work when Texinfo sources are in the package. The
+ latest version can be downloaded from
+ `http://www.gnu.org/software/texinfo/'.
+
+`ylwrap'
+ This program wraps `lex' and `yacc' to rename their output files.
+ It also ensures that, for instance, multiple `yacc' instances can
+ be invoked in a single directory in parallel.

+4 Some example packages
+***********************
+
+This section contains two small examples.
+
+ The first example (*note Complete::) assumes you have an existing
+project already using Autoconf, with handcrafted `Makefile's, and that
+you want to convert it to using Automake. If you are discovering both
+tools, it is probably better that you look at the Hello World example
+presented earlier (*note Hello World::).
+
+ The second example (*note true::) shows how two programs can be built
+from the same file, using different compilation parameters. It
+contains some technical digressions that are probably best skipped on
+first read.
+
+* Menu:
+
+* Complete:: A simple example, start to finish
+* true:: Building true and false
+
+\1f
+File: automake.info, Node: Complete, Next: true, Up: Examples
+
+4.1 A simple example, start to finish
+=====================================
+
+Let's suppose you just finished writing `zardoz', a program to make
+your head float from vortex to vortex. You've been using Autoconf to
+provide a portability framework, but your `Makefile.in's have been
+ad-hoc. You want to make them bulletproof, so you turn to Automake.
+
+ The first step is to update your `configure.ac' to include the
+commands that `automake' needs. The way to do this is to add an
+`AM_INIT_AUTOMAKE' call just after `AC_INIT':
+
+ AC_INIT([zardoz], [1.0])
+ AM_INIT_AUTOMAKE
+ ...
+
+ Since your program doesn't have any complicating factors (e.g., it
+doesn't use `gettext', it doesn't want to build a shared library),
+you're done with this part. That was easy!
+
+ Now you must regenerate `configure'. But to do that, you'll need to
+tell `autoconf' how to find the new macro you've used. The easiest way
+to do this is to use the `aclocal' program to generate your
+`aclocal.m4' for you. But wait... maybe you already have an
+`aclocal.m4', because you had to write some hairy macros for your
+program. The `aclocal' program lets you put your own macros into
+`acinclude.m4', so simply rename and then run:
+
+ mv aclocal.m4 acinclude.m4
+ aclocal
+ autoconf
+
+ Now it is time to write your `Makefile.am' for `zardoz'. Since
+`zardoz' is a user program, you want to install it where the rest of
+the user programs go: `bindir'. Additionally, `zardoz' has some
+Texinfo documentation. Your `configure.ac' script uses
+`AC_REPLACE_FUNCS', so you need to link against `$(LIBOBJS)'. So
+here's what you'd write:
+
+ bin_PROGRAMS = zardoz
+ zardoz_SOURCES = main.c head.c float.c vortex9.c gun.c
+ zardoz_LDADD = $(LIBOBJS)
+
+ info_TEXINFOS = zardoz.texi
+
+ Now you can run `automake --add-missing' to generate your
+`Makefile.in' and grab any auxiliary files you might need, and you're
+done!
+
+\1f
+File: automake.info, Node: true, Prev: Complete, Up: Examples
+
+4.2 Building true and false
+===========================
+
+Here is another, trickier example. It shows how to generate two
+programs (`true' and `false') from the same source file (`true.c').
+The difficult part is that each compilation of `true.c' requires
+different `cpp' flags.
+
+ bin_PROGRAMS = true false
+ false_SOURCES =
+ false_LDADD = false.o
+
+ true.o: true.c
+ $(COMPILE) -DEXIT_CODE=0 -c true.c
+
+ false.o: true.c
+ $(COMPILE) -DEXIT_CODE=1 -o false.o -c true.c
+
+ Note that there is no `true_SOURCES' definition. Automake will
+implicitly assume that there is a source file named `true.c' (*note
+Default _SOURCES::), and define rules to compile `true.o' and link
+`true'. The `true.o: true.c' rule supplied by the above `Makefile.am',
+will override the Automake generated rule to build `true.o'.
+
+ `false_SOURCES' is defined to be empty--that way no implicit value
+is substituted. Because we have not listed the source of `false', we
+have to tell Automake how to link the program. This is the purpose of
+the `false_LDADD' line. A `false_DEPENDENCIES' variable, holding the
+dependencies of the `false' target will be automatically generated by
+Automake from the content of `false_LDADD'.
+
+ The above rules won't work if your compiler doesn't accept both `-c'
+and `-o'. The simplest fix for this is to introduce a bogus dependency
+(to avoid problems with a parallel `make'):
+
+ true.o: true.c false.o
+ $(COMPILE) -DEXIT_CODE=0 -c true.c
+
+ false.o: true.c
+ $(COMPILE) -DEXIT_CODE=1 -c true.c && mv true.o false.o
+
+ As it turns out, there is also a much easier way to do this same
+task. Some of the above technique is useful enough that we've kept the
+example in the manual. However if you were to build `true' and `false'
+in real life, you would probably use per-program compilation flags,
+like so:
+
+ bin_PROGRAMS = false true
+
+ false_SOURCES = true.c
+ false_CPPFLAGS = -DEXIT_CODE=1
+
+ true_SOURCES = true.c
+ true_CPPFLAGS = -DEXIT_CODE=0
+
+ In this case Automake will cause `true.c' to be compiled twice, with
+different flags. In this instance, the names of the object files would
+be chosen by automake; they would be `false-true.o' and `true-true.o'.
+(The name of the object files rarely matters.)

+
+5 Creating a `Makefile.in'
+**************************
+
+To create all the `Makefile.in's for a package, run the `automake'
+program in the top level directory, with no arguments. `automake' will
+automatically find each appropriate `Makefile.am' (by scanning
+`configure.ac'; *note configure::) and generate the corresponding
+`Makefile.in'. Note that `automake' has a rather simplistic view of
+what constitutes a package; it assumes that a package has only one
+`configure.ac', at the top. If your package has multiple
+`configure.ac's, then you must run `automake' in each directory holding
+a `configure.ac'. (Alternatively, you may rely on Autoconf's
+`autoreconf', which is able to recurse your package tree and run
+`automake' where appropriate.)
+
+ You can optionally give `automake' an argument; `.am' is appended to
+the argument and the result is used as the name of the input file.
+This feature is generally only used to automatically rebuild an
+out-of-date `Makefile.in'. Note that `automake' must always be run
+from the topmost directory of a project, even if being used to
+regenerate the `Makefile.in' in some subdirectory. This is necessary
+because `automake' must scan `configure.ac', and because `automake'
+uses the knowledge that a `Makefile.in' is in a subdirectory to change
+its behavior in some cases.
+
+ Automake will run `autoconf' to scan `configure.ac' and its
+dependencies (i.e., `aclocal.m4' and any included file), therefore
+`autoconf' must be in your `PATH'. If there is an `AUTOCONF' variable
+in your environment it will be used instead of `autoconf', this allows
+you to select a particular version of Autoconf. By the way, don't
+misunderstand this paragraph: `automake' runs `autoconf' to *scan* your
+`configure.ac', this won't build `configure' and you still have to run
+`autoconf' yourself for this purpose.
+
+ `automake' accepts the following options:
+
+`-a'
+`--add-missing'
+ Automake requires certain common files to exist in certain
+ situations; for instance, `config.guess' is required if
+ `configure.ac' invokes `AC_CANONICAL_HOST'. Automake is
+ distributed with several of these files (*note Auxiliary
+ Programs::); this option will cause the missing ones to be
+ automatically added to the package, whenever possible. In general
+ if Automake tells you a file is missing, try using this option.
+ By default Automake tries to make a symbolic link pointing to its
+ own copy of the missing file; this can be changed with `--copy'.
+
+ Many of the potentially-missing files are common scripts whose
+ location may be specified via the `AC_CONFIG_AUX_DIR' macro.
+ Therefore, `AC_CONFIG_AUX_DIR''s setting affects whether a file is
+ considered missing, and where the missing file is added (*note
+ Optional::).
+
+ In some strictness modes, additional files are installed, see
+ *note Gnits:: for more information.
+
+`--libdir=DIR'
+ Look for Automake data files in directory DIR instead of in the
+ installation directory. This is typically used for debugging.
+
+`--print-libdir'
+ Print the path of the installation directory containing
+ Automake-provided scripts and data files (like e.g.,
+ `texinfo.texi' and `install-sh').
+
+`-c'
+`--copy'
+ When used with `--add-missing', causes installed files to be
+ copied. The default is to make a symbolic link.
+
+`--cygnus'
+ Causes the generated `Makefile.in's to follow Cygnus rules, instead
+ of GNU or Gnits rules. For more information, see *note Cygnus::.
+ Note that _this mode of operation is deprecated, and will be
+ removed_ in the next major Automake release (1.13).
+
+`-f'
+`--force-missing'
+ When used with `--add-missing', causes standard files to be
+ reinstalled even if they already exist in the source tree. This
+ involves removing the file from the source tree before creating
+ the new symlink (or, with `--copy', copying the new file).
+
+`--foreign'
+ Set the global strictness to `foreign'. For more information, see
+ *note Strictness::.
+
+`--gnits'
+ Set the global strictness to `gnits'. For more information, see
+ *note Gnits::.
+
+`--gnu'
+ Set the global strictness to `gnu'. For more information, see
+ *note Gnits::. This is the default strictness.
+
+`--help'
+ Print a summary of the command line options and exit.
+
+`-i'
+`--ignore-deps'
+ This disables the dependency tracking feature in generated
+ `Makefile's; see *note Dependencies::.
+
+`--include-deps'
+ This enables the dependency tracking feature. This feature is
+ enabled by default. This option is provided for historical
+ reasons only and probably should not be used.
+
+`--no-force'
+ Ordinarily `automake' creates all `Makefile.in's mentioned in
+ `configure.ac'. This option causes it to only update those
+ `Makefile.in's that are out of date with respect to one of their
+ dependents.
+
+`-o DIR'
+`--output-dir=DIR'
+ Put the generated `Makefile.in' in the directory DIR. Ordinarily
+ each `Makefile.in' is created in the directory of the
+ corresponding `Makefile.am'. This option is deprecated and will be
+ removed in a future release.
+
+`-v'
+`--verbose'
+ Cause Automake to print information about which files are being
+ read or created.
+
+`--version'
+ Print the version number of Automake and exit.
+
+`-W CATEGORY'
+`--warnings=CATEGORY'
+ Output warnings falling in CATEGORY. CATEGORY can be one of:
+ `gnu'
+ warnings related to the GNU Coding Standards (*note Top:
+ (standards)Top.).
+
+ `obsolete'
+ obsolete features or constructions
+
+ `override'
+ user redefinitions of Automake rules or variables
+
+ `portability'
+ portability issues (e.g., use of `make' features that are
+ known to be not portable)
+
+ `extra-portability'
+ extra portability issues related to obscure tools. One
+ example of such a tool is the Microsoft `lib' archiver.
+
+ `syntax'
+ weird syntax, unused variables, typos
+
+ `unsupported'
+ unsupported or incomplete features
+
+ `all'
+ all the warnings
+
+ `none'
+ turn off all the warnings
+
+ `error'
+ treat warnings as errors
+
+ A category can be turned off by prefixing its name with `no-'. For
+ instance, `-Wno-syntax' will hide the warnings about unused
+ variables.
+
+ The categories output by default are `syntax' and `unsupported'.
+ Additionally, `gnu' and `portability' are enabled in `--gnu' and
+ `--gnits' strictness. On the other hand, the `silent-rules'
+ options (*note Options::) turns off portability warnings about
+ recursive variable expansions.
+
+ Turning off `portability' will also turn off `extra-portability',
+ and similarly turning on `extra-portability' will also turn on
+ `portability'. However, turning on `portability' or turning off
+ `extra-portability' will not affect the other category.
+
+ The environment variable `WARNINGS' can contain a comma separated
+ list of categories to enable. It will be taken into account
+ before the command-line switches, this way `-Wnone' will also
+ ignore any warning category enabled by `WARNINGS'. This variable
+ is also used by other tools like `autoconf'; unknown categories
+ are ignored for this reason.
+
+
+ If the environment variable `AUTOMAKE_JOBS' contains a positive
+number, it is taken as the maximum number of Perl threads to use in
+`automake' for generating multiple `Makefile.in' files concurrently.
+This is an experimental feature.

+6 Scanning `configure.ac', using `aclocal'
+******************************************
+
+Automake scans the package's `configure.ac' to determine certain
+information about the package. Some `autoconf' macros are required and
+some variables must be defined in `configure.ac'. Automake will also
+use information from `configure.ac' to further tailor its output.
+
+ Automake also supplies some Autoconf macros to make the maintenance
+easier. These macros can automatically be put into your `aclocal.m4'
+using the `aclocal' program.

+
+6.1 Configuration requirements
+==============================
+
+The one real requirement of Automake is that your `configure.ac' call
+`AM_INIT_AUTOMAKE'. This macro does several things that are required
+for proper Automake operation (*note Macros::).
+
+ Here are the other macros that Automake requires but which are not
+run by `AM_INIT_AUTOMAKE':
+
+`AC_CONFIG_FILES'
+`AC_OUTPUT'
+ These two macros are usually invoked as follows near the end of
+ `configure.ac'.
+
+ ...
+ AC_CONFIG_FILES([
+ Makefile
+ doc/Makefile
+ src/Makefile
+ src/lib/Makefile
+ ...
+ ])
+ AC_OUTPUT
+
+ Automake uses these to determine which files to create (*note
+ Creating Output Files: (autoconf)Output.). A listed file is
+ considered to be an Automake generated `Makefile' if there exists
+ a file with the same name and the `.am' extension appended.
+ Typically, `AC_CONFIG_FILES([foo/Makefile])' will cause Automake to
+ generate `foo/Makefile.in' if `foo/Makefile.am' exists.
+
+ When using `AC_CONFIG_FILES' with multiple input files, as in
+
+ AC_CONFIG_FILES([Makefile:top.in:Makefile.in:bot.in])
+
+ `automake' will generate the first `.in' input file for which a
+ `.am' file exists. If no such file exists the output file is not
+ considered to be generated by Automake.
+
+ Files created by `AC_CONFIG_FILES', be they Automake `Makefile's
+ or not, are all removed by `make distclean'. Their inputs are
+ automatically distributed, unless they are the output of prior
+ `AC_CONFIG_FILES' commands. Finally, rebuild rules are generated
+ in the Automake `Makefile' existing in the subdirectory of the
+ output file, if there is one, or in the top-level `Makefile'
+ otherwise.
+
+ The above machinery (cleaning, distributing, and rebuilding) works
+ fine if the `AC_CONFIG_FILES' specifications contain only
+ literals. If part of the specification uses shell variables,
+ `automake' will not be able to fulfill this setup, and you will
+ have to complete the missing bits by hand. For instance, on
+
+ file=input
+ ...
+ AC_CONFIG_FILES([output:$file],, [file=$file])
+
+ `automake' will output rules to clean `output', and rebuild it.
+ However the rebuild rule will not depend on `input', and this file
+ will not be distributed either. (You must add `EXTRA_DIST =
+ input' to your `Makefile.am' if `input' is a source file.)
+
+ Similarly
+
+ file=output
+ file2=out:in
+ ...
+ AC_CONFIG_FILES([$file:input],, [file=$file])
+ AC_CONFIG_FILES([$file2],, [file2=$file2])
+
+ will only cause `input' to be distributed. No file will be
+ cleaned automatically (add `DISTCLEANFILES = output out'
+ yourself), and no rebuild rule will be output.
+
+ Obviously `automake' cannot guess what value `$file' is going to
+ hold later when `configure' is run, and it cannot use the shell
+ variable `$file' in a `Makefile'. However, if you make reference
+ to `$file' as `${file}' (i.e., in a way that is compatible with
+ `make''s syntax) and furthermore use `AC_SUBST' to ensure that
+ `${file}' is meaningful in a `Makefile', then `automake' will be
+ able to use `${file}' to generate all these rules. For instance,
+ here is how the Automake package itself generates versioned
+ scripts for its test suite:
+
+ AC_SUBST([APIVERSION], ...)
+ ...
+ AC_CONFIG_FILES(
+ [tests/aclocal-${APIVERSION}:tests/aclocal.in],
+ [chmod +x tests/aclocal-${APIVERSION}],
+ [APIVERSION=$APIVERSION])
+ AC_CONFIG_FILES(
+ [tests/automake-${APIVERSION}:tests/automake.in],
+ [chmod +x tests/automake-${APIVERSION}])
+
+ Here cleaning, distributing, and rebuilding are done automatically,
+ because `${APIVERSION}' is known at `make'-time.
+
+ Note that you should not use shell variables to declare `Makefile'
+ files for which `automake' must create `Makefile.in'. Even
+ `AC_SUBST' does not help here, because `automake' needs to know
+ the file name when it runs in order to check whether `Makefile.am'
+ exists. (In the very hairy case that your setup requires such use
+ of variables, you will have to tell Automake which `Makefile.in's
+ to generate on the command-line.)
+
+ It is possible to let `automake' emit conditional rules for
+ `AC_CONFIG_FILES' with the help of `AM_COND_IF' (*note Optional::).
+
+ To summarize:
+ * Use literals for `Makefile's, and for other files whenever
+ possible.
+
+ * Use `$file' (or `${file}' without `AC_SUBST([file])') for
+ files that `automake' should ignore.
+
+ * Use `${file}' and `AC_SUBST([file])' for files that
+ `automake' should not ignore.

+
+6.2 Other things Automake recognizes
+====================================
+
+Every time Automake is run it calls Autoconf to trace `configure.ac'.
+This way it can recognize the use of certain macros and tailor the
+generated `Makefile.in' appropriately. Currently recognized macros and
+their effects are:
+
+`AC_CANONICAL_BUILD'
+`AC_CANONICAL_HOST'
+`AC_CANONICAL_TARGET'
+ Automake will ensure that `config.guess' and `config.sub' exist.
+ Also, the `Makefile' variables `build_triplet', `host_triplet' and
+ `target_triplet' are introduced. See *note Getting the Canonical
+ System Type: (autoconf)Canonicalizing.
+
+`AC_CONFIG_AUX_DIR'
+ Automake will look for various helper scripts, such as
+ `install-sh', in the directory named in this macro invocation.
+ (The full list of scripts is: `ar-lib', `config.guess',
+ `config.sub', `depcomp', `elisp-comp', `compile', `install-sh',
+ `ltmain.sh', `mdate-sh', `missing', `mkinstalldirs', `py-compile',
+ `test-driver', `texinfo.tex', `ylwrap'.) Not all scripts are
+ always searched for; some scripts will only be sought if the
+ generated `Makefile.in' requires them.
+
+ If `AC_CONFIG_AUX_DIR' is not given, the scripts are looked for in
+ their standard locations. For `mdate-sh', `texinfo.tex', and
+ `ylwrap', the standard location is the source directory
+ corresponding to the current `Makefile.am'. For the rest, the
+ standard location is the first one of `.', `..', or `../..'
+ (relative to the top source directory) that provides any one of
+ the helper scripts. *Note Finding `configure' Input:
+ (autoconf)Input.
+
+ Required files from `AC_CONFIG_AUX_DIR' are automatically
+ distributed, even if there is no `Makefile.am' in this directory.
+
+`AC_CONFIG_LIBOBJ_DIR'
+ Automake will require the sources file declared with
+ `AC_LIBSOURCE' (see below) in the directory specified by this
+ macro.
+
+`AC_CONFIG_HEADERS'
+ Automake will generate rules to rebuild these headers. Older
+ versions of Automake required the use of `AM_CONFIG_HEADER' (*note
+ Macros::); this is no longer the case.
+
+ As with `AC_CONFIG_FILES' (*note Requirements::), parts of the
+ specification using shell variables will be ignored as far as
+ cleaning, distributing, and rebuilding is concerned.
+
+`AC_CONFIG_LINKS'
+ Automake will generate rules to remove `configure' generated links
+ on `make distclean' and to distribute named source files as part
+ of `make dist'.
+
+ As for `AC_CONFIG_FILES' (*note Requirements::), parts of the
+ specification using shell variables will be ignored as far as
+ cleaning and distributing is concerned. (There are no rebuild
+ rules for links.)
+
+`AC_LIBOBJ'
+`AC_LIBSOURCE'
+`AC_LIBSOURCES'
+ Automake will automatically distribute any file listed in
+ `AC_LIBSOURCE' or `AC_LIBSOURCES'.
+
+ Note that the `AC_LIBOBJ' macro calls `AC_LIBSOURCE'. So if an
+ Autoconf macro is documented to call `AC_LIBOBJ([file])', then
+ `file.c' will be distributed automatically by Automake. This
+ encompasses many macros like `AC_FUNC_ALLOCA', `AC_FUNC_MEMCMP',
+ `AC_REPLACE_FUNCS', and others.
+
+ By the way, direct assignments to `LIBOBJS' are no longer
+ supported. You should always use `AC_LIBOBJ' for this purpose.
+ *Note `AC_LIBOBJ' vs. `LIBOBJS': (autoconf)AC_LIBOBJ vs LIBOBJS.
+
+`AC_PROG_RANLIB'
+ This is required if any libraries are built in the package. *Note
+ Particular Program Checks: (autoconf)Particular Programs.
+
+`AC_PROG_CXX'
+ This is required if any C++ source is included. *Note Particular
+ Program Checks: (autoconf)Particular Programs.
+
+`AC_PROG_OBJC'
+ This is required if any Objective C source is included. *Note
+ Particular Program Checks: (autoconf)Particular Programs.
+
+`AC_PROG_OBJCXX'
+ This is required if any Objective C++ source is included. *Note
+ Particular Program Checks: (autoconf)Particular Programs.
+
+`AC_PROG_F77'
+ This is required if any Fortran 77 source is included. *Note
+ Particular Program Checks: (autoconf)Particular Programs.
+
+`AC_F77_LIBRARY_LDFLAGS'
+ This is required for programs and shared libraries that are a
+ mixture of languages that include Fortran 77 (*note Mixing Fortran
+ 77 With C and C++::). *Note Autoconf macros supplied with
+ Automake: Macros.
+
+`AC_FC_SRCEXT'
+ Automake will add the flags computed by `AC_FC_SRCEXT' to
+ compilation of files with the respective source extension (*note
+ Fortran Compiler Characteristics: (autoconf)Fortran Compiler.).
+
+`AC_PROG_FC'
+ This is required if any Fortran 90/95 source is included. This
+ macro is distributed with Autoconf version 2.58 and later. *Note
+ Particular Program Checks: (autoconf)Particular Programs.
+
+`AC_PROG_LIBTOOL'
+ Automake will turn on processing for `libtool' (*note
+ Introduction: (libtool)Top.).
+
+`AC_PROG_YACC'
+ If a Yacc source file is seen, then you must either use this macro
+ or define the variable `YACC' in `configure.ac'. The former is
+ preferred (*note Particular Program Checks: (autoconf)Particular
+ Programs.).
+
+`AC_PROG_LEX'
+ If a Lex source file is seen, then this macro must be used. *Note
+ Particular Program Checks: (autoconf)Particular Programs.
+
+`AC_REQUIRE_AUX_FILE'
+ For each `AC_REQUIRE_AUX_FILE([FILE])', `automake' will ensure
+ that `FILE' exists in the aux directory, and will complain
+ otherwise. It will also automatically distribute the file. This
+ macro should be used by third-party Autoconf macros that require
+ some supporting files in the aux directory specified with
+ `AC_CONFIG_AUX_DIR' above. *Note Finding `configure' Input:
+ (autoconf)Input.
+
+`AC_SUBST'
+ The first argument is automatically defined as a variable in each
+ generated `Makefile.in', unless `AM_SUBST_NOTMAKE' is also used
+ for this variable. *Note Setting Output Variables:
+ (autoconf)Setting Output Variables.
+
+ For every substituted variable VAR, `automake' will add a line
+ `VAR = VALUE' to each `Makefile.in' file. Many Autoconf macros
+ invoke `AC_SUBST' to set output variables this way, e.g.,
+ `AC_PATH_XTRA' defines `X_CFLAGS' and `X_LIBS'. Thus, you can
+ access these variables as `$(X_CFLAGS)' and `$(X_LIBS)' in any
+ `Makefile.am' if `AC_PATH_XTRA' is called.
+
+`AM_CONDITIONAL'
+ This introduces an Automake conditional (*note Conditionals::).
+
+`AM_COND_IF'
+ This macro allows `automake' to detect subsequent access within
+ `configure.ac' to a conditional previously introduced with
+ `AM_CONDITIONAL', thus enabling conditional `AC_CONFIG_FILES'
+ (*note Usage of Conditionals::).
+
+`AM_GNU_GETTEXT'
+ This macro is required for packages that use GNU gettext (*note
+ gettext::). It is distributed with gettext. If Automake sees
+ this macro it ensures that the package meets some of gettext's
+ requirements.
+
+`AM_GNU_GETTEXT_INTL_SUBDIR'
+ This macro specifies that the `intl/' subdirectory is to be built,
+ even if the `AM_GNU_GETTEXT' macro was invoked with a first
+ argument of `external'.
+
+`AM_MAINTAINER_MODE([DEFAULT-MODE])'
+ This macro adds an `--enable-maintainer-mode' option to
+ `configure'. If this is used, `automake' will cause
+ "maintainer-only" rules to be turned off by default in the
+ generated `Makefile.in's, unless DEFAULT-MODE is `enable'. This
+ macro defines the `MAINTAINER_MODE' conditional, which you can use
+ in your own `Makefile.am'. *Note maintainer-mode::.
+
+`AM_SUBST_NOTMAKE(VAR)'
+ Prevent Automake from defining a variable VAR, even if it is
+ substituted by `config.status'. Normally, Automake defines a
+ `make' variable for each `configure' substitution, i.e., for each
+ `AC_SUBST([VAR])'. This macro prevents that definition from
+ Automake. If `AC_SUBST' has not been called for this variable,
+ then `AM_SUBST_NOTMAKE' has no effects. Preventing variable
+ definitions may be useful for substitution of multi-line values,
+ where `VAR = @VALUE@' might yield unintended results.
+
+`m4_include'
+ Files included by `configure.ac' using this macro will be detected
+ by Automake and automatically distributed. They will also appear
+ as dependencies in `Makefile' rules.
+
+ `m4_include' is seldom used by `configure.ac' authors, but can
+ appear in `aclocal.m4' when `aclocal' detects that some required
+ macros come from files local to your package (as opposed to macros
+ installed in a system-wide directory, *note aclocal Invocation::).
+
+

+
+6.3 Auto-generating aclocal.m4
+==============================
+
+Automake includes a number of Autoconf macros that can be used in your
+package (*note Macros::); some of them are actually required by
+Automake in certain situations. These macros must be defined in your
+`aclocal.m4'; otherwise they will not be seen by `autoconf'.
+
+ The `aclocal' program will automatically generate `aclocal.m4' files
+based on the contents of `configure.ac'. This provides a convenient
+way to get Automake-provided macros, without having to search around.
+The `aclocal' mechanism allows other packages to supply their own
+macros (*note Extending aclocal::). You can also use it to maintain
+your own set of custom macros (*note Local Macros::).
+
+ At startup, `aclocal' scans all the `.m4' files it can find, looking
+for macro definitions (*note Macro Search Path::). Then it scans
+`configure.ac'. Any mention of one of the macros found in the first
+step causes that macro, and any macros it in turn requires, to be put
+into `aclocal.m4'.
+
+ _Putting_ the file that contains the macro definition into
+`aclocal.m4' is usually done by copying the entire text of this file,
+including unused macro definitions as well as both `#' and `dnl'
+comments. If you want to make a comment that will be completely
+ignored by `aclocal', use `##' as the comment leader.
+
+ When a file selected by `aclocal' is located in a subdirectory
+specified as a relative search path with `aclocal''s `-I' argument,
+`aclocal' assumes the file belongs to the package and uses `m4_include'
+instead of copying it into `aclocal.m4'. This makes the package
+smaller, eases dependency tracking, and cause the file to be
+distributed automatically. (*Note Local Macros::, for an example.)
+Any macro that is found in a system-wide directory, or via an absolute
+search path will be copied. So use `-I `pwd`/reldir' instead of `-I
+reldir' whenever some relative directory should be considered outside
+the package.
+
+ The contents of `acinclude.m4', if this file exists, are also
+automatically included in `aclocal.m4'. We recommend against using
+`acinclude.m4' in new packages (*note Local Macros::).
+
+ While computing `aclocal.m4', `aclocal' runs `autom4te' (*note Using
+`Autom4te': (autoconf)Using autom4te.) in order to trace the macros
+that are really used, and omit from `aclocal.m4' all macros that are
+mentioned but otherwise unexpanded (this can happen when a macro is
+called conditionally). `autom4te' is expected to be in the `PATH',
+just as `autoconf'. Its location can be overridden using the
+`AUTOM4TE' environment variable.

+
+6.3.1 aclocal Options
+---------------------
+
+`aclocal' accepts the following options:
+
+`--automake-acdir=DIR'
+ Look for the automake-provided macro files in DIR instead of in
+ the installation directory. This is typically used for debugging.
+
+`--system-acdir=DIR'
+ Look for the system-wide third-party macro files (and the special
+ `dirlist' file) in DIR instead of in the installation directory.
+ This is typically used for debugging.
+
+`--diff[=COMMAND]'
+ Run COMMAND on M4 file that would be installed or overwritten by
+ `--install'. The default COMMAND is `diff -u'. This option
+ implies `--install' and `--dry-run'.
+
+`--dry-run'
+ Do not actually overwrite (or create) `aclocal.m4' and M4 files
+ installed by `--install'.
+
+`--help'
+ Print a summary of the command line options and exit.
+
+`-I DIR'
+ Add the directory DIR to the list of directories searched for
+ `.m4' files.
+
+`--install'
+ Install system-wide third-party macros into the first directory
+ specified with `-I DIR' instead of copying them in the output file.
+ Note that this will happen also if DIR is an absolute path.
+
+ When this option is used, and only when this option is used,
+ `aclocal' will also honor `#serial NUMBER' lines that appear in
+ macros: an M4 file is ignored if there exists another M4 file with
+ the same basename and a greater serial number in the search path
+ (*note Serials::).
+
+`--force'
+ Always overwrite the output file. The default is to overwrite the
+ output file only when really needed, i.e., when its contents
+ changes or if one of its dependencies is younger.
+
+ This option forces the update of `aclocal.m4' (or the file
+ specified with `--output' below) and only this file, it has
+ absolutely no influence on files that may need to be installed by
+ `--install'.
+
+`--output=FILE'
+ Cause the output to be put into FILE instead of `aclocal.m4'.
+
+`--print-ac-dir'
+ Prints the name of the directory that `aclocal' will search to
+ find third-party `.m4' files. When this option is given, normal
+ processing is suppressed. This option was used _in the past_ by
+ third-party packages to determine where to install `.m4' macro
+ files, but _this usage is today discouraged_, since it causes
+ `$(prefix)' not to be thoroughly honoured (which violates the GNU
+ Coding Standards), and a similar semantics can be better obtained
+ with the `ACLOCAL_PATH' environment variable; *note Extending
+ aclocal::.
+
+`--verbose'
+ Print the names of the files it examines.
+
+`--version'
+ Print the version number of Automake and exit.
+
+`-W CATEGORY'
+
+`--warnings=CATEGORY'
+ Output warnings falling in CATEGORY. CATEGORY can be one of:
+ `syntax'
+ dubious syntactic constructs, underquoted macros, unused
+ macros, etc.
+
+ `unsupported'
+ unknown macros
+
+ `all'
+ all the warnings, this is the default
+
+ `none'
+ turn off all the warnings
+
+ `error'
+ treat warnings as errors
+
+ All warnings are output by default.
+
+ The environment variable `WARNINGS' is honored in the same way as
+ it is for `automake' (*note automake Invocation::).
+

+\1f
+File: automake.info, Node: Macro Search Path, Next: Extending aclocal, Prev: aclocal Options, Up: aclocal Invocation
+
+6.3.2 Macro Search Path
+-----------------------
+
+By default, `aclocal' searches for `.m4' files in the following
+directories, in this order:
+
+`ACDIR-APIVERSION'
+ This is where the `.m4' macros distributed with Automake itself
+ are stored. APIVERSION depends on the Automake release used; for
+ example, for Automake 1.11.x, APIVERSION = `1.11'.
+
+`ACDIR'
+ This directory is intended for third party `.m4' files, and is
+ configured when `automake' itself is built. This is
+ `@datadir@/aclocal/', which typically expands to
+ `${prefix}/share/aclocal/'. To find the compiled-in value of
+ ACDIR, use the `--print-ac-dir' option (*note aclocal Options::).
+
+ As an example, suppose that `automake-1.11.2' was configured with
+`--prefix=/usr/local'. Then, the search path would be:
+
+ 1. `/usr/local/share/aclocal-1.11.2/'
+
+ 2. `/usr/local/share/aclocal/'
+
+ The paths for the ACDIR and ACDIR-APIVERSION directories can be
+changed respectively through aclocal options `--system-acdir' and
+`--automake-acdir' (*note aclocal Options::). Note however that these
+options are only intended for use by the internal Automake test suite,
+or for debugging under highly unusual situations; they are not
+ordinarily needed by end-users.
+
+ As explained in (*note aclocal Options::), there are several options
+that can be used to change or extend this search path.
+
+Modifying the Macro Search Path: `-I DIR'
+.........................................
+
+Any extra directories specified using `-I' options (*note aclocal
+Options::) are _prepended_ to this search list. Thus, `aclocal -I /foo
+-I /bar' results in the following search path:
+
+ 1. `/foo'
+
+ 2. `/bar'
+
+ 3. ACDIR-APIVERSION
+
+ 4. ACDIR
+
+Modifying the Macro Search Path: `dirlist'
+..........................................
+
+There is a third mechanism for customizing the search path. If a
+`dirlist' file exists in ACDIR, then that file is assumed to contain a
+list of directory patterns, one per line. `aclocal' expands these
+patterns to directory names, and adds them to the search list _after_
+all other directories. `dirlist' entries may use shell wildcards such
+as `*', `?', or `[...]'.
+
+ For example, suppose `ACDIR/dirlist' contains the following:
+
+ /test1
+ /test2
+ /test3*
+
+and that `aclocal' was called with the `-I /foo -I /bar' options.
+Then, the search path would be
+
+ 1. `/foo'
+
+ 2. `/bar'
+
+ 3. ACDIR-APIVERSION
+
+ 4. ACDIR
+
+ 5. `/test1'
+
+ 6. `/test2'
+
+and all directories with path names starting with `/test3'.
+
+ If the `--system-acdir=DIR' option is used, then `aclocal' will
+search for the `dirlist' file in DIR; but remember the warnings above
+against the use of `--system-acdir'.
+
+ `dirlist' is useful in the following situation: suppose that
+`automake' version `1.11.2' is installed with `--prefix=/usr' by the
+system vendor. Thus, the default search directories are
+
+ 1. `/usr/share/aclocal-1.11/'
+
+ 2. `/usr/share/aclocal/'
+
+ However, suppose further that many packages have been manually
+installed on the system, with $prefix=/usr/local, as is typical. In
+that case, many of these "extra" `.m4' files are in
+`/usr/local/share/aclocal'. The only way to force `/usr/bin/aclocal'
+to find these "extra" `.m4' files is to always call `aclocal -I
+/usr/local/share/aclocal'. This is inconvenient. With `dirlist', one
+may create a file `/usr/share/aclocal/dirlist' containing only the
+single line
+
+ /usr/local/share/aclocal
+
+ Now, the "default" search path on the affected system is
+
+ 1. `/usr/share/aclocal-1.11/'
+
+ 2. `/usr/share/aclocal/'
+
+ 3. `/usr/local/share/aclocal/'
+
+ without the need for `-I' options; `-I' options can be reserved for
+project-specific needs (`my-source-dir/m4/'), rather than using it to
+work around local system-dependent tool installation directories.
+
+ Similarly, `dirlist' can be handy if you have installed a local copy
+of Automake in your account and want `aclocal' to look for macros
+installed at other places on the system.
+
+Modifying the Macro Search Path: `ACLOCAL_PATH'
+...............................................
+
+The fourth and last mechanism to customize the macro search path is
+also the simplest. Any directory included in the colon-separated
+environment variable `ACLOCAL_PATH' is added to the search path and
+takes precedence over system directories (including those found via
+`dirlist'), with the exception of the versioned directory
+ACDIR-APIVERSION (*note Macro Search Path::). However, directories
+passed via `-I' will take precedence over directories in `ACLOCAL_PATH'.
+
+ Also note that, if the `--install' option is used, any `.m4' file
+containing a required macro that is found in a directory listed in
+`ACLOCAL_PATH' will be installed locally. In this case, serial numbers
+in `.m4' are honoured too, *note Serials::.
+
+ Conversely to `dirlist', `ACLOCAL_PATH' is useful if you are using a
+global copy of Automake and want `aclocal' to look for macros somewhere
+under your home directory.
+
+Planned future incompatibilities
+................................
+
+The order in which the directories in the macro search path are
+currently looked up is confusing and/or suboptimal in various aspects,
+and is probably going to be changed in the future Automake release. In
+particular, directories in `ACLOCAL_PATH' and `ACDIR' might end up
+taking precedence over `ACDIR-APIVERSION', and directories in
+`ACDIR/dirlist' might end up taking precedence over `ACDIR'. _This is
+a possible future incompatibility!_

+File: automake.info, Node: Extending aclocal, Next: Local Macros, Prev: Macro Search Path, Up: aclocal Invocation
+
+6.3.3 Writing your own aclocal macros
+-------------------------------------
+
+The `aclocal' program doesn't have any built-in knowledge of any
+macros, so it is easy to extend it with your own macros.
+
+ This can be used by libraries that want to supply their own Autoconf
+macros for use by other programs. For instance, the `gettext' library
+supplies a macro `AM_GNU_GETTEXT' that should be used by any package
+using `gettext'. When the library is installed, it installs this macro
+so that `aclocal' will find it.
+
+ A macro file's name should end in `.m4'. Such files should be
+installed in `$(datadir)/aclocal'. This is as simple as writing:
+
+ aclocaldir = $(datadir)/aclocal
+ aclocal_DATA = mymacro.m4 myothermacro.m4
+
+Please do use `$(datadir)/aclocal', and not something based on the
+result of `aclocal --print-ac-dir' (*note Hard-Coded Install Paths::,
+for arguments). It might also be helpful to suggest to the user to add
+the `$(datadir)/aclocal' directory to his `ACLOCAL_PATH' variable
+(*note ACLOCAL_PATH::) so that `aclocal' will find the `.m4' files
+installed by your package automatically.
+
+ A file of macros should be a series of properly quoted `AC_DEFUN''s
+(*note Macro Definitions: (autoconf)Macro Definitions.). The `aclocal'
+programs also understands `AC_REQUIRE' (*note Prerequisite Macros:
+(autoconf)Prerequisite Macros.), so it is safe to put each macro in a
+separate file. Each file should have no side effects but macro
+definitions. Especially, any call to `AC_PREREQ' should be done inside
+the defined macro, not at the beginning of the file.
+
+ Starting with Automake 1.8, `aclocal' will warn about all
+underquoted calls to `AC_DEFUN'. We realize this will annoy a lot of
+people, because `aclocal' was not so strict in the past and many third
+party macros are underquoted; and we have to apologize for this
+temporary inconvenience. The reason we have to be stricter is that a
+future implementation of `aclocal' (*note Future of aclocal::) will
+have to temporarily include all these third party `.m4' files, maybe
+several times, including even files that are not actually needed.
+Doing so should alleviate many problems of the current implementation,
+however it requires a stricter style from the macro authors. Hopefully
+it is easy to revise the existing macros. For instance,
+
+ # bad style
+ AC_PREREQ(2.68)
+ AC_DEFUN(AX_FOOBAR,
+ [AC_REQUIRE([AX_SOMETHING])dnl
+ AX_FOO
+ AX_BAR
+ ])
+
+should be rewritten as
+
+ AC_DEFUN([AX_FOOBAR],
+ [AC_PREREQ([2.68])dnl
+ AC_REQUIRE([AX_SOMETHING])dnl
+ AX_FOO
+ AX_BAR
+ ])
+
+ Wrapping the `AC_PREREQ' call inside the macro ensures that Autoconf
+2.68 will not be required if `AX_FOOBAR' is not actually used. Most
+importantly, quoting the first argument of `AC_DEFUN' allows the macro
+to be redefined or included twice (otherwise this first argument would
+be expanded during the second definition). For consistency we like to
+quote even arguments such as `2.68' that do not require it.
+
+ If you have been directed here by the `aclocal' diagnostic but are
+not the maintainer of the implicated macro, you will want to contact
+the maintainer of that macro. Please make sure you have the latest
+version of the macro and that the problem hasn't already been reported
+before doing so: people tend to work faster when they aren't flooded by
+mails.
+
+ Another situation where `aclocal' is commonly used is to manage
+macros that are used locally by the package, *note Local Macros::.

+
+6.3.4 Handling Local Macros
+---------------------------
+
+Feature tests offered by Autoconf do not cover all needs. People often
+have to supplement existing tests with their own macros, or with
+third-party macros.
+
+ There are two ways to organize custom macros in a package.
+
+ The first possibility (the historical practice) is to list all your
+macros in `acinclude.m4'. This file will be included in `aclocal.m4'
+when you run `aclocal', and its macro(s) will henceforth be visible to
+`autoconf'. However if it contains numerous macros, it will rapidly
+become difficult to maintain, and it will be almost impossible to share
+macros between packages.
+
+ The second possibility, which we do recommend, is to write each macro
+in its own file and gather all these files in a directory. This
+directory is usually called `m4/'. To build `aclocal.m4', one should
+therefore instruct `aclocal' to scan `m4/'. From the command line,
+this is done with `aclocal -I m4'. The top-level `Makefile.am' should
+also be updated to define
+
+ ACLOCAL_AMFLAGS = -I m4
+
+ `ACLOCAL_AMFLAGS' contains options to pass to `aclocal' when
+`aclocal.m4' is to be rebuilt by `make'. This line is also used by
+`autoreconf' (*note Using `autoreconf' to Update `configure' Scripts:
+(autoconf)autoreconf Invocation.) to run `aclocal' with suitable
+options, or by `autopoint' (*note Invoking the `autopoint' Program:
+(gettext)autopoint Invocation.) and `gettextize' (*note Invoking the
+`gettextize' Program: (gettext)gettextize Invocation.) to locate the
+place where Gettext's macros should be installed. So even if you do
+not really care about the rebuild rules, you should define
+`ACLOCAL_AMFLAGS'.
+
+ When `aclocal -I m4' is run, it will build an `aclocal.m4' that
+`m4_include's any file from `m4/' that defines a required macro.
+Macros not found locally will still be searched in system-wide
+directories, as explained in *note Macro Search Path::.
+
+ Custom macros should be distributed for the same reason that
+`configure.ac' is: so that other people have all the sources of your
+package if they want to work on it. Actually, this distribution
+happens automatically because all `m4_include'd files are distributed.
+
+ However there is no consensus on the distribution of third-party
+macros that your package may use. Many libraries install their own
+macro in the system-wide `aclocal' directory (*note Extending
+aclocal::). For instance, Guile ships with a file called `guile.m4'
+that contains the macro `GUILE_FLAGS' that can be used to define setup
+compiler and linker flags appropriate for using Guile. Using
+`GUILE_FLAGS' in `configure.ac' will cause `aclocal' to copy `guile.m4'
+into `aclocal.m4', but as `guile.m4' is not part of the project, it
+will not be distributed. Technically, that means a user who needs to
+rebuild `aclocal.m4' will have to install Guile first. This is
+probably OK, if Guile already is a requirement to build the package.
+However, if Guile is only an optional feature, or if your package might
+run on architectures where Guile cannot be installed, this requirement
+will hinder development. An easy solution is to copy such third-party
+macros in your local `m4/' directory so they get distributed.
+
+ Since Automake 1.10, `aclocal' offers an option to copy these
+system-wide third-party macros in your local macro directory, solving
+the above problem. Simply use:
+
+ ACLOCAL_AMFLAGS = -I m4 --install
+
+With this setup, system-wide macros will be copied to `m4/' the first
+time you run `autoreconf'. Then the locally installed macros will have
+precedence over the system-wide installed macros each time `aclocal' is
+run again.
+
+ One reason why you should keep `--install' in the flags even after
+the first run is that when you later edit `configure.ac' and depend on
+a new macro, this macro will be installed in your `m4/' automatically.
+Another one is that serial numbers (*note Serials::) can be used to
+update the macros in your source tree automatically when new
+system-wide versions are installed. A serial number should be a single
+line of the form
+
+ #serial NNN
+
+where NNN contains only digits and dots. It should appear in the M4
+file before any macro definition. It is a good practice to maintain a
+serial number for each macro you distribute, even if you do not use the
+`--install' option of `aclocal': this allows other people to use it.
+
+\1f
+File: automake.info, Node: Serials, Next: Future of aclocal, Prev: Local Macros, Up: aclocal Invocation
+
+6.3.5 Serial Numbers
+--------------------
+
+Because third-party macros defined in `*.m4' files are naturally shared
+between multiple projects, some people like to version them. This
+makes it easier to tell which of two M4 files is newer. Since at least
+1996, the tradition is to use a `#serial' line for this.
+
+ A serial number should be a single line of the form
+
+ # serial VERSION
+
+where VERSION is a version number containing only digits and dots.
+Usually people use a single integer, and they increment it each time
+they change the macro (hence the name of "serial"). Such a line should
+appear in the M4 file before any macro definition.
+
+ The `#' must be the first character on the line, and it is OK to
+have extra words after the version, as in
+
+ #serial VERSION GARBAGE
+
+ Normally these serial numbers are completely ignored by `aclocal'
+and `autoconf', like any genuine comment. However when using
+`aclocal''s `--install' feature, these serial numbers will modify the
+way `aclocal' selects the macros to install in the package: if two
+files with the same basename exist in your search path, and if at least
+one of them uses a `#serial' line, `aclocal' will ignore the file that
+has the older `#serial' line (or the file that has none).
+
+ Note that a serial number applies to a whole M4 file, not to any
+macro it contains. A file can contains multiple macros, but only one
+serial.
+
+ Here is a use case that illustrates the use of `--install' and its
+interaction with serial numbers. Let's assume we maintain a package
+called MyPackage, the `configure.ac' of which requires a third-party
+macro `AX_THIRD_PARTY' defined in `/usr/share/aclocal/thirdparty.m4' as
+follows:
+
+ # serial 1
+ AC_DEFUN([AX_THIRD_PARTY], [...])
+
+ MyPackage uses an `m4/' directory to store local macros as explained
+in *note Local Macros::, and has
+
+ ACLOCAL_AMFLAGS = -I m4 --install
+
+in its top-level `Makefile.am'.
+
+ Initially the `m4/' directory is empty. The first time we run
+`autoreconf', it will fetch the options to pass to `aclocal' in
+`Makefile.am', and run `aclocal -I m4 --install'. `aclocal' will
+notice that
+
+ * `configure.ac' uses `AX_THIRD_PARTY'
+
+ * No local macros define `AX_THIRD_PARTY'
+
+ * `/usr/share/aclocal/thirdparty.m4' defines `AX_THIRD_PARTY' with
+ serial 1.
+
+Because `/usr/share/aclocal/thirdparty.m4' is a system-wide macro and
+`aclocal' was given the `--install' option, it will copy this file in
+`m4/thirdparty.m4', and output an `aclocal.m4' that contains
+`m4_include([m4/thirdparty.m4])'.
+
+ The next time `aclocal -I m4 --install' is run (either via
+`autoreconf', by hand, or from the `Makefile' rebuild rules) something
+different happens. `aclocal' notices that
+
+ * `configure.ac' uses `AX_THIRD_PARTY'
+
+ * `m4/thirdparty.m4' defines `AX_THIRD_PARTY' with serial 1.
+
+ * `/usr/share/aclocal/thirdparty.m4' defines `AX_THIRD_PARTY' with
+ serial 1.
+
+Because both files have the same serial number, `aclocal' uses the
+first it found in its search path order (*note Macro Search Path::).
+`aclocal' therefore ignores `/usr/share/aclocal/thirdparty.m4' and
+outputs an `aclocal.m4' that contains `m4_include([m4/thirdparty.m4])'.
+
+ Local directories specified with `-I' are always searched before
+system-wide directories, so a local file will always be preferred to
+the system-wide file in case of equal serial numbers.
+
+ Now suppose the system-wide third-party macro is changed. This can
+happen if the package installing this macro is updated. Let's suppose
+the new macro has serial number 2. The next time `aclocal -I m4
+--install' is run the situation is the following:
+
+ * `configure.ac' uses `AX_THIRD_PARTY'
+
+ * `m4/thirdparty.m4' defines `AX_THIRD_PARTY' with serial 1.
+
+ * `/usr/share/aclocal/thirdparty.m4' defines `AX_THIRD_PARTY' with
+ serial 2.
+
+When `aclocal' sees a greater serial number, it immediately forgets
+anything it knows from files that have the same basename and a smaller
+serial number. So after it has found
+`/usr/share/aclocal/thirdparty.m4' with serial 2, `aclocal' will
+proceed as if it had never seen `m4/thirdparty.m4'. This brings us
+back to a situation similar to that at the beginning of our example,
+where no local file defined the macro. `aclocal' will install the new
+version of the macro in `m4/thirdparty.m4', in this case overriding the
+old version. MyPackage just had its macro updated as a side effect of
+running `aclocal'.
+
+ If you are leery of letting `aclocal' update your local macro, you
+can run `aclocal -I m4 --diff' to review the changes `aclocal -I m4
+--install' would perform on these macros.
+
+ Finally, note that the `--force' option of `aclocal' has absolutely
+no effect on the files installed by `--install'. For instance, if you
+have modified your local macros, do not expect `--install --force' to
+replace the local macros by their system-wide versions. If you want to
+do so, simply erase the local macros you want to revert, and run
+`aclocal -I m4 --install'.
+

+
+6.3.6 The Future of `aclocal'
+-----------------------------
+
+`aclocal' is expected to disappear. This feature really should not be
+offered by Automake. Automake should focus on generating `Makefile's;
+dealing with M4 macros really is Autoconf's job. The fact that some
+people install Automake just to use `aclocal', but do not use
+`automake' otherwise is an indication of how that feature is misplaced.
+
+ The new implementation will probably be done slightly differently.
+For instance, it could enforce the `m4/'-style layout discussed in
+*note Local Macros::.
+
+ We have no idea when and how this will happen. This has been
+discussed several times in the past, but someone still has to commit to
+that non-trivial task.
+
+ From the user point of view, `aclocal''s removal might turn out to
+be painful. There is a simple precaution that you may take to make
+that switch more seamless: never call `aclocal' yourself. Keep this
+guy under the exclusive control of `autoreconf' and Automake's rebuild
+rules. Hopefully you won't need to worry about things breaking, when
+`aclocal' disappears, because everything will have been taken care of.
+If otherwise you used to call `aclocal' directly yourself or from some
+script, you will quickly notice the change.
+
+ Many packages come with a script called `bootstrap.sh' or
+`autogen.sh', that will just call `aclocal', `libtoolize', `gettextize'
+or `autopoint', `autoconf', `autoheader', and `automake' in the right
+order. Actually this is precisely what `autoreconf' can do for you.
+If your package has such a `bootstrap.sh' or `autogen.sh' script,
+consider using `autoreconf'. That should simplify its logic a lot
+(less things to maintain, yum!), it's even likely you will not need the
+script anymore, and more to the point you will not call `aclocal'
+directly anymore.
+
+ For the time being, third-party packages should continue to install
+public macros into `/usr/share/aclocal/'. If `aclocal' is replaced by
+another tool it might make sense to rename the directory, but
+supporting `/usr/share/aclocal/' for backward compatibility should be
+really easy provided all macros are properly written (*note Extending
+aclocal::).

+
+6.4 Autoconf macros supplied with Automake
+==========================================
+
+Automake ships with several Autoconf macros that you can use from your
+`configure.ac'. When you use one of them it will be included by
+`aclocal' in `aclocal.m4'.
+
+* Menu:
+
+* Public Macros:: Macros that you can use.
+* Obsolete Macros:: Macros that will soon be removed.
+* Private Macros:: Macros that you should not use.
+
+\1f
+File: automake.info, Node: Public Macros, Next: Obsolete Macros, Up: Macros
+
+6.4.1 Public Macros
+-------------------
+
+`AM_INIT_AUTOMAKE([OPTIONS])'
+ Runs many macros required for proper operation of the generated
+ Makefiles.
+
+ Today, `AM_INIT_AUTOMAKE' is called with a single argument: a
+ space-separated list of Automake options that should be applied to
+ every `Makefile.am' in the tree. The effect is as if each option
+ were listed in `AUTOMAKE_OPTIONS' (*note Options::).
+
+ This macro can also be called in _another, deprecated form_
+ (support for which will be _removed in the next major Automake
+ release (1.13)_): `AM_INIT_AUTOMAKE(PACKAGE, VERSION,
+ [NO-DEFINE])'. In this form, there are two required arguments:
+ the package and the version number. This form is obsolete because
+ the PACKAGE and VERSION can be obtained from Autoconf's `AC_INIT'
+ macro (which itself has an old and a new form).
+
+ If your `configure.ac' has:
+
+ AC_INIT([src/foo.c])
+ AM_INIT_AUTOMAKE([mumble], [1.5])
+
+ you should modernize it as follows:
+
+ AC_INIT([mumble], [1.5])
+ AC_CONFIG_SRCDIR([src/foo.c])
+ AM_INIT_AUTOMAKE
+
+ Note that if you're upgrading your `configure.ac' from an earlier
+ version of Automake, it is not always correct to simply move the
+ package and version arguments from `AM_INIT_AUTOMAKE' directly to
+ `AC_INIT', as in the example above. The first argument to
+ `AC_INIT' should be the name of your package (e.g., `GNU
+ Automake'), not the tarball name (e.g., `automake') that you used
+ to pass to `AM_INIT_AUTOMAKE'. Autoconf tries to derive a tarball
+ name from the package name, which should work for most but not all
+ package names. (If it doesn't work for yours, you can use the
+ four-argument form of `AC_INIT' to provide the tarball name
+ explicitly).
+
+ By default this macro `AC_DEFINE''s `PACKAGE' and `VERSION'. This
+ can be avoided by passing the `no-define' option:
+ AM_INIT_AUTOMAKE([gnits 1.5 no-define dist-bzip2])
+
+`AM_PATH_LISPDIR'
+ Searches for the program `emacs', and, if found, sets the output
+ variable `lispdir' to the full path to Emacs' site-lisp directory.
+
+ Note that this test assumes the `emacs' found to be a version that
+ supports Emacs Lisp (such as GNU Emacs or XEmacs). Other emacsen
+ can cause this test to hang (some, like old versions of
+ MicroEmacs, start up in interactive mode, requiring `C-x C-c' to
+ exit, which is hardly obvious for a non-emacs user). In most
+ cases, however, you should be able to use `C-c' to kill the test.
+ In order to avoid problems, you can set `EMACS' to "no" in the
+ environment, or use the `--with-lispdir' option to `configure' to
+ explicitly set the correct path (if you're sure you have an
+ `emacs' that supports Emacs Lisp).
+
+`AM_PROG_AR([ACT-IF-FAIL])'
+ You must use this macro when you use the archiver in your project,
+ if you want support for unusual archivers such as Microsoft `lib'.
+ The content of the optional argument is executed if the archiver
+ interface is not recognized; the default action is to abort
+ configure with an error message.
+
+`AM_PROG_AS'
+ Use this macro when you have assembly code in your project. This
+ will choose the assembler for you (by default the C compiler) and
+ set `CCAS', and will also set `CCASFLAGS' if required.
+
+`AM_PROG_CC_C_O'
+ This is like `AC_PROG_CC_C_O', but it generates its results in the
+ manner required by Automake. You must use this instead of
+ `AC_PROG_CC_C_O' when you need this functionality, that is, when
+ using per-target flags or subdir-objects with C sources.
+
+`AM_PROG_LEX'
+ Like `AC_PROG_LEX' (*note Particular Program Checks:
+ (autoconf)Particular Programs.), but uses the `missing' script on
+ systems that do not have `lex'. HP-UX 10 is one such system.
+
+`AM_PROG_GCJ'
+ This macro finds the `gcj' program or causes an error. It sets
+ `GCJ' and `GCJFLAGS'. `gcj' is the Java front-end to the GNU
+ Compiler Collection.
+
+`AM_PROG_UPC([COMPILER-SEARCH-LIST])'
+ Find a compiler for Unified Parallel C and define the `UPC'
+ variable. The default COMPILER-SEARCH-LIST is `upcc upc'. This
+ macro will abort `configure' if no Unified Parallel C compiler is
+ found.
+
+`AM_SILENT_RULES'
+ Enable the machinery for less verbose build output (*note
+ Options::).
+
+`AM_WITH_DMALLOC'
+ Add support for the Dmalloc package (http://dmalloc.com/). If the
+ user runs `configure' with `--with-dmalloc', then define
+ `WITH_DMALLOC' and add `-ldmalloc' to `LIBS'.
+

+
+6.4.2 Obsolete Macros
+---------------------
+
+Although using some of the following macros was required in past
+releases, you should not use any of them in new code. _All these
+macros will be removed in the next major Automake version_; if you are
+still using them, running `autoupdate' should adjust your
+`configure.ac' automatically (*note Using `autoupdate' to Modernize
+`configure.ac': (autoconf)autoupdate Invocation.). _Do it NOW!_
+
+`AM_CONFIG_HEADER'
+ Automake will generate rules to automatically regenerate the config
+ header. This obsolete macro is a synonym of `AC_CONFIG_HEADERS'
+ today (*note Optional::).
+
+`AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL'
+ If the use of `TIOCGWINSZ' requires `<sys/ioctl.h>', then define
+ `GWINSZ_IN_SYS_IOCTL'. Otherwise `TIOCGWINSZ' can be found in
+ `<termios.h>'. This macro is obsolete, you should use Autoconf's
+ `AC_HEADER_TIOCGWINSZ' instead.
+
+`AM_PROG_MKDIR_P'
+ From Automake 1.8 to 1.9.6 this macro used to define the output
+ variable `mkdir_p' to one of `mkdir -p', `install-sh -d', or
+ `mkinstalldirs'.
+
+ Nowadays Autoconf provides a similar functionality with
+ `AC_PROG_MKDIR_P' (*note Particular Program Checks:
+ (autoconf)Particular Programs.), however this defines the output
+ variable `MKDIR_P' instead. In case you are still using the
+ `AM_PROG_MKDIR_P' macro in your `configure.ac', or its provided
+ variable `$(mkdir_p)' in your `Makefile.am', you are advised to
+ switch ASAP to the more modern Autoconf-provided interface
+ instead; both the macro and the variable _will be removed_ in the
+ next major Automake release.
+
+`AM_SYS_POSIX_TERMIOS'
+ Check to see if POSIX termios headers and functions are available
+ on the system. If so, set the shell variable
+ `am_cv_sys_posix_termios' to `yes'. If not, set the variable to
+ `no'. This macro is obsolete, you should use Autoconf's
+ `AC_SYS_POSIX_TERMIOS' instead.

+6.4.3 Private Macros
+--------------------
+
+The following macros are private macros you should not call directly.
+They are called by the other public macros when appropriate. Do not
+rely on them, as they might be changed in a future version. Consider
+them as implementation details; or better, do not consider them at all:

+
+`_AM_DEPENDENCIES'
+`AM_SET_DEPDIR'
+`AM_DEP_TRACK'
+`AM_OUTPUT_DEPENDENCY_COMMANDS'
+ These macros are used to implement Automake's automatic dependency
+ tracking scheme. They are called automatically by Automake when
+ required, and there should be no need to invoke them manually.
+
+`AM_MAKE_INCLUDE'
+ This macro is used to discover how the user's `make' handles
+ `include' statements. This macro is automatically invoked when
+ needed; there should be no need to invoke it manually.
+
+`AM_PROG_INSTALL_STRIP'
+ This is used to find a version of `install' that can be used to
+ strip a program at installation time. This macro is automatically
+ included when required.
+
+`AM_SANITY_CHECK'
+ This checks to make sure that a file created in the build
+ directory is newer than a file in the source directory. This can
+ fail on systems where the clock is set incorrectly. This macro is
+ automatically run from `AM_INIT_AUTOMAKE'.

+
+For simple projects that distribute all files in the same directory it

+place.
+
+ In larger projects it is common to organize files in different
+directories, in a tree. For instance one directory per program, per
+library or per module. The traditional approach is to build these
+subdirectories recursively: each directory contains its `Makefile'

+level directory it enters each subdirectory in turn to build its
+contents.

+
+7.1 Recursing subdirectories
+============================
+
+In packages with subdirectories, the top level `Makefile.am' must tell
+Automake which subdirectories are to be built. This is done via the
+`SUBDIRS' variable.
+
+ The `SUBDIRS' variable holds a list of subdirectories in which
+building of various sorts can occur. The rules for many targets (e.g.,
+`all') in the generated `Makefile' will run commands both locally and
+in all specified subdirectories. Note that the directories listed in
+`SUBDIRS' are not required to contain `Makefile.am's; only `Makefile's
+(after configuration). This allows inclusion of libraries from
+packages that do not use Automake (such as `gettext'; see also *note
+Third-Party Makefiles::).
+
+ In packages that use subdirectories, the top-level `Makefile.am' is
+often very short. For instance, here is the `Makefile.am' from the GNU
+Hello distribution:
+
+ EXTRA_DIST = BUGS ChangeLog.O README-alpha
+ SUBDIRS = doc intl po src tests
+
+ When Automake invokes `make' in a subdirectory, it uses the value of
+the `MAKE' variable. It passes the value of the variable
+`AM_MAKEFLAGS' to the `make' invocation; this can be set in
+`Makefile.am' if there are flags you must always pass to `make'.
+
+ The directories mentioned in `SUBDIRS' are usually direct children
+of the current directory, each subdirectory containing its own
+`Makefile.am' with a `SUBDIRS' pointing to deeper subdirectories.
+Automake can be used to construct packages of arbitrary depth this way.
+
+ By default, Automake generates `Makefiles' that work depth-first in
+postfix order: the subdirectories are built before the current
+directory. However, it is possible to change this ordering. You can
+do this by putting `.' into `SUBDIRS'. For instance, putting `.' first
+will cause a prefix ordering of directories.
+
+ Using
+
+ SUBDIRS = lib src . test
+
+will cause `lib/' to be built before `src/', then the current directory
+will be built, finally the `test/' directory will be built. It is
+customary to arrange test directories to be built after everything else
+since they are meant to test what has been constructed.
+
+ All `clean' rules are run in reverse order of build rules.
+
+\1f
+File: automake.info, Node: Conditional Subdirectories, Next: Alternative, Prev: Subdirectories, Up: Directories
+
+7.2 Conditional Subdirectories
+==============================
+
+It is possible to define the `SUBDIRS' variable conditionally if, like
+in the case of GNU Inetutils, you want to only build a subset of the
+entire package.
+
+ To illustrate how this works, let's assume we have two directories
+`src/' and `opt/'. `src/' should always be built, but we want to
+decide in `configure' whether `opt/' will be built or not. (For this
+example we will assume that `opt/' should be built when the variable
+`$want_opt' was set to `yes'.)
+
+ Running `make' should thus recurse into `src/' always, and then
+maybe in `opt/'.
+
+ However `make dist' should always recurse into both `src/' and
+`opt/'. Because `opt/' should be distributed even if it is not needed
+in the current configuration. This means `opt/Makefile' should be
+created _unconditionally_.
+
+ There are two ways to setup a project like this. You can use
+Automake conditionals (*note Conditionals::) or use Autoconf `AC_SUBST'
+variables (*note Setting Output Variables: (autoconf)Setting Output
+Variables.). Using Automake conditionals is the preferred solution.
+Before we illustrate these two possibilities, let's introduce
+`DIST_SUBDIRS'.

+
+7.2.1 `SUBDIRS' vs. `DIST_SUBDIRS'
+----------------------------------
+
+Automake considers two sets of directories, defined by the variables
+`SUBDIRS' and `DIST_SUBDIRS'.
+
+ `SUBDIRS' contains the subdirectories of the current directory that
+must be built (*note Subdirectories::). It must be defined manually;
+Automake will never guess a directory is to be built. As we will see
+in the next two sections, it is possible to define it conditionally so
+that some directory will be omitted from the build.
+
+ `DIST_SUBDIRS' is used in rules that need to recurse in all
+directories, even those that have been conditionally left out of the
+build. Recall our example where we may not want to build subdirectory
+`opt/', but yet we want to distribute it? This is where `DIST_SUBDIRS'
+comes into play: `opt' may not appear in `SUBDIRS', but it must appear
+in `DIST_SUBDIRS'.
+
+ Precisely, `DIST_SUBDIRS' is used by `make maintainer-clean', `make
+distclean' and `make dist'. All other recursive rules use `SUBDIRS'.
+
+ If `SUBDIRS' is defined conditionally using Automake conditionals,
+Automake will define `DIST_SUBDIRS' automatically from the possible
+values of `SUBDIRS' in all conditions.
+
+ If `SUBDIRS' contains `AC_SUBST' variables, `DIST_SUBDIRS' will not
+be defined correctly because Automake does not know the possible values
+of these variables. In this case `DIST_SUBDIRS' needs to be defined
+manually.
+
+\1f
+File: automake.info, Node: Subdirectories with AM_CONDITIONAL, Next: Subdirectories with AC_SUBST, Prev: SUBDIRS vs DIST_SUBDIRS, Up: Conditional Subdirectories
+
+7.2.2 Subdirectories with `AM_CONDITIONAL'
+------------------------------------------
+
+`configure' should output the `Makefile' for each directory and define
+a condition into which `opt/' should be built.
+
+ ...
+ AM_CONDITIONAL([COND_OPT], [test "$want_opt" = yes])
+ AC_CONFIG_FILES([Makefile src/Makefile opt/Makefile])
+ ...
+
+ Then `SUBDIRS' can be defined in the top-level `Makefile.am' as
+follows.
+
+ if COND_OPT
+ MAYBE_OPT = opt
+ endif
+ SUBDIRS = src $(MAYBE_OPT)
+
+ As you can see, running `make' will rightly recurse into `src/' and
+maybe `opt/'.
+
+ As you can't see, running `make dist' will recurse into both `src/'
+and `opt/' directories because `make dist', unlike `make all', doesn't
+use the `SUBDIRS' variable. It uses the `DIST_SUBDIRS' variable.
+
+ In this case Automake will define `DIST_SUBDIRS = src opt'
+automatically because it knows that `MAYBE_OPT' can contain `opt' in
+some condition.
+
+\1f
+File: automake.info, Node: Subdirectories with AC_SUBST, Next: Unconfigured Subdirectories, Prev: Subdirectories with AM_CONDITIONAL, Up: Conditional Subdirectories
+
+7.2.3 Subdirectories with `AC_SUBST'
+------------------------------------
+
+Another possibility is to define `MAYBE_OPT' from `./configure' using
+`AC_SUBST':
+
+ ...
+ if test "$want_opt" = yes; then
+ MAYBE_OPT=opt
+ else
+ MAYBE_OPT=
+ fi
+ AC_SUBST([MAYBE_OPT])
+ AC_CONFIG_FILES([Makefile src/Makefile opt/Makefile])
+ ...
+
+ In this case the top-level `Makefile.am' should look as follows.
+
+ SUBDIRS = src $(MAYBE_OPT)
+ DIST_SUBDIRS = src opt
+
+ The drawback is that since Automake cannot guess what the possible
+values of `MAYBE_OPT' are, it is necessary to define `DIST_SUBDIRS'.
+
+\1f
+File: automake.info, Node: Unconfigured Subdirectories, Prev: Subdirectories with AC_SUBST, Up: Conditional Subdirectories
+
+7.2.4 Unconfigured Subdirectories
+---------------------------------
+
+The semantics of `DIST_SUBDIRS' are often misunderstood by some users
+that try to _configure and build_ subdirectories conditionally. Here
+by configuring we mean creating the `Makefile' (it might also involve
+running a nested `configure' script: this is a costly operation that
+explains why people want to do it conditionally, but only the `Makefile'
+is relevant to the discussion).
+
+ The above examples all assume that every `Makefile' is created, even
+in directories that are not going to be built. The simple reason is
+that we want `make dist' to distribute even the directories that are
+not being built (e.g., platform-dependent code), hence `make dist' must
+recurse into the subdirectory, hence this directory must be configured
+and appear in `DIST_SUBDIRS'.
+
+ Building packages that do not configure every subdirectory is a
+tricky business, and we do not recommend it to the novice as it is easy
+to produce an incomplete tarball by mistake. We will not discuss this
+topic in depth here, yet for the adventurous here are a few rules to
+remember.
+
+ * `SUBDIRS' should always be a subset of `DIST_SUBDIRS'.
+
+ It makes little sense to have a directory in `SUBDIRS' that is not
+ in `DIST_SUBDIRS'. Think of the former as a way to tell which
+ directories listed in the latter should be built.
+
+ * Any directory listed in `DIST_SUBDIRS' and `SUBDIRS' must be
+ configured.
+
+ I.e., the `Makefile' must exists or the recursive `make' rules
+ will not be able to process the directory.
+
+ * Any configured directory must be listed in `DIST_SUBDIRS'.
+
+ So that the cleaning rules remove the generated `Makefile's. It
+ would be correct to see `DIST_SUBDIRS' as a variable that lists
+ all the directories that have been configured.
+
+ In order to prevent recursion in some unconfigured directory you
+must therefore ensure that this directory does not appear in
+`DIST_SUBDIRS' (and `SUBDIRS'). For instance, if you define `SUBDIRS'
+conditionally using `AC_SUBST' and do not define `DIST_SUBDIRS'
+explicitly, it will be default to `$(SUBDIRS)'; another possibility is
+to force `DIST_SUBDIRS = $(SUBDIRS)'.
+
+ Of course, directories that are omitted from `DIST_SUBDIRS' will not
+be distributed unless you make other arrangements for this to happen
+(for instance, always running `make dist' in a configuration where all
+directories are known to appear in `DIST_SUBDIRS'; or writing a
+`dist-hook' target to distribute these directories).
+
+ In few packages, unconfigured directories are not even expected to
+be distributed. Although these packages do not require the
+aforementioned extra arrangements, there is another pitfall. If the
+name of a directory appears in `SUBDIRS' or `DIST_SUBDIRS', `automake'
+will make sure the directory exists. Consequently `automake' cannot be
+run on such a distribution when one directory has been omitted. One
+way to avoid this check is to use the `AC_SUBST' method to declare
+conditional directories; since `automake' does not know the values of
+`AC_SUBST' variables it cannot ensure the corresponding directory
+exists.

+
+7.3 An Alternative Approach to Subdirectories
+=============================================
+
+If you've ever read Peter Miller's excellent paper, Recursive Make
+Considered Harmful (http://miller.emu.id.au/pmiller/books/rmch/), the
+preceding sections on the use of subdirectories will probably come as
+unwelcome advice. For those who haven't read the paper, Miller's main
+thesis is that recursive `make' invocations are both slow and
+error-prone.
+
+ Automake provides sufficient cross-directory support (1) to enable
+you to write a single `Makefile.am' for a complex multi-directory
+package.
+
+ By default an installable file specified in a subdirectory will have
+its directory name stripped before installation. For instance, in this
+example, the header file will be installed as `$(includedir)/stdio.h':
+
+ include_HEADERS = inc/stdio.h
+
+ However, the `nobase_' prefix can be used to circumvent this path
+stripping. In this example, the header file will be installed as
+`$(includedir)/sys/types.h':
+
+ nobase_include_HEADERS = sys/types.h
+
+ `nobase_' should be specified first when used in conjunction with
+either `dist_' or `nodist_' (*note Fine-grained Distribution
+Control::). For instance:
+
+ nobase_dist_pkgdata_DATA = images/vortex.pgm sounds/whirl.ogg
+
+ Finally, note that a variable using the `nobase_' prefix can often
+be replaced by several variables, one for each destination directory
+(*note Uniform::). For instance, the last example could be rewritten
+as follows:
+
+ imagesdir = $(pkgdatadir)/images
+ soundsdir = $(pkgdatadir)/sounds
+ dist_images_DATA = images/vortex.pgm
+ dist_sounds_DATA = sounds/whirl.ogg
+
+This latter syntax makes it possible to change one destination
+directory without changing the layout of the source tree.
+
+ Currently, `nobase_*_LTLIBRARIES' are the only exception to this
+rule, in that there is no particular installation order guarantee for
+an otherwise equivalent set of variables without `nobase_' prefix.

+
+7.4 Nesting Packages
+====================
+
+In the GNU Build System, packages can be nested to arbitrary depth.
+This means that a package can embed other packages with their own
+`configure', `Makefile's, etc.
+
+ These other packages should just appear as subdirectories of their
+parent package. They must be listed in `SUBDIRS' like other ordinary
+directories. However the subpackage's `Makefile's should be output by
+its own `configure' script, not by the parent's `configure'. This is
+achieved using the `AC_CONFIG_SUBDIRS' Autoconf macro (*note
+AC_CONFIG_SUBDIRS: (autoconf)Subdirectories.).
+
+ Here is an example package for an `arm' program that links with a
+`hand' library that is a nested package in subdirectory `hand/'.
+
+ `arm''s `configure.ac':
+
+ AC_INIT([arm], [1.0])
+ AC_CONFIG_AUX_DIR([.])
+ AM_INIT_AUTOMAKE
+ AC_PROG_CC
+ AC_CONFIG_FILES([Makefile])
+ # Call hand's ./configure script recursively.
+ AC_CONFIG_SUBDIRS([hand])
+ AC_OUTPUT
+
+ `arm''s `Makefile.am':
+
+ # Build the library in the hand subdirectory first.
+ SUBDIRS = hand
+
+ # Include hand's header when compiling this directory.
+ AM_CPPFLAGS = -I$(srcdir)/hand
+
+ bin_PROGRAMS = arm
+ arm_SOURCES = arm.c
+ # link with the hand library.
+ arm_LDADD = hand/libhand.a
+
+ Now here is `hand''s `hand/configure.ac':
+
+ AC_INIT([hand], [1.2])
+ AC_CONFIG_AUX_DIR([.])
+ AM_INIT_AUTOMAKE
+ AC_PROG_CC
+ AM_PROG_AR
+ AC_PROG_RANLIB
+ AC_CONFIG_FILES([Makefile])
+ AC_OUTPUT
+
+and its `hand/Makefile.am':
+
+ lib_LIBRARIES = libhand.a
+ libhand_a_SOURCES = hand.c
+
+ When `make dist' is run from the top-level directory it will create
+an archive `arm-1.0.tar.gz' that contains the `arm' code as well as the
+`hand' subdirectory. This package can be built and installed like any
+ordinary package, with the usual `./configure && make && make install'
+sequence (the `hand' subpackage will be built and installed by the
+process).
+
+ When `make dist' is run from the hand directory, it will create a
+self-contained `hand-1.2.tar.gz' archive. So although it appears to be
+embedded in another package, it can still be used separately.
+
+ The purpose of the `AC_CONFIG_AUX_DIR([.])' instruction is to force
+Automake and Autoconf to search for auxiliary scripts in the current
+directory. For instance, this means that there will be two copies of
+`install-sh': one in the top-level of the `arm' package, and another
+one in the `hand/' subdirectory for the `hand' package.
+
+ The historical default is to search for these auxiliary scripts in
+the parent directory and the grandparent directory. So if the
+`AC_CONFIG_AUX_DIR([.])' line was removed from `hand/configure.ac',
+that subpackage would share the auxiliary script of the `arm' package.
+This may looks like a gain in size (a few kilobytes), but it is
+actually a loss of modularity as the `hand' subpackage is no longer
+self-contained (`make dist' in the subdirectory will not work anymore).
+
+ Packages that do not use Automake need more work to be integrated
+this way. *Note Third-Party Makefiles::.

+8.1 Building a program
+======================
+
+In order to build a program, you need to tell Automake which sources
+are part of it, and which libraries it should be linked with.
+
+ This section also covers conditional compilation of sources or
+programs. Most of the comments about these also apply to libraries
+(*note A Library::) and libtool libraries (*note A Shared Library::).

+\1f
+File: automake.info, Node: Program Sources, Next: Linking, Up: A Program
+
+8.1.1 Defining program sources
+------------------------------
+
+In a directory containing source that gets built into a program (as
+opposed to a library or a script), the `PROGRAMS' primary is used.
+Programs can be installed in `bindir', `sbindir', `libexecdir',
+`pkglibexecdir', or not at all (`noinst_'). They can also be built
+only for `make check', in which case the prefix is `check_'.
+
+ For instance:
+
+ bin_PROGRAMS = hello
+
+ In this simple case, the resulting `Makefile.in' will contain code
+to generate a program named `hello'.
+
+ Associated with each program are several assisting variables that are
+named after the program. These variables are all optional, and have
+reasonable defaults. Each variable, its use, and default is spelled out
+below; we use the "hello" example throughout.
+
+ The variable `hello_SOURCES' is used to specify which source files
+get built into an executable:
+
+ hello_SOURCES = hello.c version.c getopt.c getopt1.c getopt.h system.h
+
+ This causes each mentioned `.c' file to be compiled into the
+corresponding `.o'. Then all are linked to produce `hello'.
+
+ If `hello_SOURCES' is not specified, then it defaults to the single
+file `hello.c' (*note Default _SOURCES::).
+
+ Multiple programs can be built in a single directory. Multiple
+programs can share a single source file, which must be listed in each
+`_SOURCES' definition.
+
+ Header files listed in a `_SOURCES' definition will be included in
+the distribution but otherwise ignored. In case it isn't obvious, you
+should not include the header file generated by `configure' in a
+`_SOURCES' variable; this file should not be distributed. Lex (`.l')
+and Yacc (`.y') files can also be listed; see *note Yacc and Lex::.
+
+\1f
+File: automake.info, Node: Linking, Next: Conditional Sources, Prev: Program Sources, Up: A Program
+
+8.1.2 Linking the program
+-------------------------
+
+If you need to link against libraries that are not found by
+`configure', you can use `LDADD' to do so. This variable is used to
+specify additional objects or libraries to link with; it is
+inappropriate for specifying specific linker flags, you should use
+`AM_LDFLAGS' for this purpose.
+
+ Sometimes, multiple programs are built in one directory but do not
+share the same link-time requirements. In this case, you can use the
+`PROG_LDADD' variable (where PROG is the name of the program as it
+appears in some `_PROGRAMS' variable, and usually written in lowercase)
+to override `LDADD'. If this variable exists for a given program, then
+that program is not linked using `LDADD'.
+
+ For instance, in GNU cpio, `pax', `cpio' and `mt' are linked against
+the library `libcpio.a'. However, `rmt' is built in the same
+directory, and has no such link requirement. Also, `mt' and `rmt' are
+only built on certain architectures. Here is what cpio's
+`src/Makefile.am' looks like (abridged):
+
+ bin_PROGRAMS = cpio pax $(MT)
+ libexec_PROGRAMS = $(RMT)
+ EXTRA_PROGRAMS = mt rmt
+
+ LDADD = ../lib/libcpio.a $(INTLLIBS)
+ rmt_LDADD =
+
+ cpio_SOURCES = ...
+ pax_SOURCES = ...
+ mt_SOURCES = ...
+ rmt_SOURCES = ...
+
+ `PROG_LDADD' is inappropriate for passing program-specific linker
+flags (except for `-l', `-L', `-dlopen' and `-dlpreopen'). So, use the
+`PROG_LDFLAGS' variable for this purpose.
+
+ It is also occasionally useful to have a program depend on some other
+target that is not actually part of that program. This can be done
+using either the `PROG_DEPENDENCIES' or the `EXTRA_PROG_DEPENDENCIES'
+variable. Each program depends on the contents both variables, but no
+further interpretation is done.
+
+ Since these dependencies are associated to the link rule used to
+create the programs they should normally list files used by the link
+command. That is `*.$(OBJEXT)', `*.a', or `*.la' files. In rare cases
+you may need to add other kinds of files such as linker scripts, but
+_listing a source file in `_DEPENDENCIES' is wrong_. If some source
+file needs to be built before all the components of a program are
+built, consider using the `BUILT_SOURCES' variable instead (*note
+Sources::).
+
+ If `PROG_DEPENDENCIES' is not supplied, it is computed by Automake.
+The automatically-assigned value is the contents of `PROG_LDADD', with
+most configure substitutions, `-l', `-L', `-dlopen' and `-dlpreopen'
+options removed. The configure substitutions that are left in are only
+`$(LIBOBJS)' and `$(ALLOCA)'; these are left because it is known that
+they will not cause an invalid value for `PROG_DEPENDENCIES' to be
+generated.
+
+ *note Conditional Sources:: shows a situation where `_DEPENDENCIES'
+may be used.
+
+ The `EXTRA_PROG_DEPENDENCIES' may be useful for cases where you
+merely want to augment the `automake'-generated `PROG_DEPENDENCIES'
+rather than replacing it.
+
+ We recommend that you avoid using `-l' options in `LDADD' or
+`PROG_LDADD' when referring to libraries built by your package.
+Instead, write the file name of the library explicitly as in the above
+`cpio' example. Use `-l' only to list third-party libraries. If you
+follow this rule, the default value of `PROG_DEPENDENCIES' will list
+all your local libraries and omit the other ones.
+
+\1f
+File: automake.info, Node: Conditional Sources, Next: Conditional Programs, Prev: Linking, Up: A Program
+
+8.1.3 Conditional compilation of sources
+----------------------------------------
+
+You can't put a configure substitution (e.g., `@FOO@' or `$(FOO)' where
+`FOO' is defined via `AC_SUBST') into a `_SOURCES' variable. The
+reason for this is a bit hard to explain, but suffice to say that it
+simply won't work. Automake will give an error if you try to do this.
+
+ Fortunately there are two other ways to achieve the same result.
+One is to use configure substitutions in `_LDADD' variables, the other
+is to use an Automake conditional.
+
+Conditional Compilation using `_LDADD' Substitutions
+....................................................
+
+Automake must know all the source files that could possibly go into a
+program, even if not all the files are built in every circumstance. Any
+files that are only conditionally built should be listed in the
+appropriate `EXTRA_' variable. For instance, if `hello-linux.c' or
+`hello-generic.c' were conditionally included in `hello', the
+`Makefile.am' would contain:
+
+ bin_PROGRAMS = hello
+ hello_SOURCES = hello-common.c
+ EXTRA_hello_SOURCES = hello-linux.c hello-generic.c
+ hello_LDADD = $(HELLO_SYSTEM)
+ hello_DEPENDENCIES = $(HELLO_SYSTEM)
+
+You can then setup the `$(HELLO_SYSTEM)' substitution from
+`configure.ac':
+
+ ...
+ case $host in
+ *linux*) HELLO_SYSTEM='hello-linux.$(OBJEXT)' ;;
+ *) HELLO_SYSTEM='hello-generic.$(OBJEXT)' ;;
+ esac
+ AC_SUBST([HELLO_SYSTEM])
+ ...
+
+ In this case, the variable `HELLO_SYSTEM' should be replaced by
+either `hello-linux.o' or `hello-generic.o', and added to both
+`hello_DEPENDENCIES' and `hello_LDADD' in order to be built and linked
+in.
+
+Conditional Compilation using Automake Conditionals
+...................................................
+
+An often simpler way to compile source files conditionally is to use
+Automake conditionals. For instance, you could use this `Makefile.am'
+construct to build the same `hello' example:
+
+ bin_PROGRAMS = hello
+ if LINUX
+ hello_SOURCES = hello-linux.c hello-common.c
+ else
+ hello_SOURCES = hello-generic.c hello-common.c
+ endif
+
+ In this case, `configure.ac' should setup the `LINUX' conditional
+using `AM_CONDITIONAL' (*note Conditionals::).
+
+ When using conditionals like this you don't need to use the `EXTRA_'
+variable, because Automake will examine the contents of each variable
+to construct the complete list of source files.
+
+ If your program uses a lot of files, you will probably prefer a
+conditional `+='.
+
+ bin_PROGRAMS = hello
+ hello_SOURCES = hello-common.c
+ if LINUX
+ hello_SOURCES += hello-linux.c
+ else
+ hello_SOURCES += hello-generic.c
+ endif
+
+\1f
+File: automake.info, Node: Conditional Programs, Prev: Conditional Sources, Up: A Program
+
+8.1.4 Conditional compilation of programs
+-----------------------------------------
+
+Sometimes it is useful to determine the programs that are to be built
+at configure time. For instance, GNU `cpio' only builds `mt' and `rmt'
+under special circumstances. The means to achieve conditional
+compilation of programs are the same you can use to compile source
+files conditionally: substitutions or conditionals.
+
+Conditional Programs using `configure' Substitutions
+....................................................
+
+In this case, you must notify Automake of all the programs that can
+possibly be built, but at the same time cause the generated
+`Makefile.in' to use the programs specified by `configure'. This is
+done by having `configure' substitute values into each `_PROGRAMS'
+definition, while listing all optionally built programs in
+`EXTRA_PROGRAMS'.
+
+ bin_PROGRAMS = cpio pax $(MT)
+ libexec_PROGRAMS = $(RMT)
+ EXTRA_PROGRAMS = mt rmt
+
+ As explained in *note EXEEXT::, Automake will rewrite
+`bin_PROGRAMS', `libexec_PROGRAMS', and `EXTRA_PROGRAMS', appending
+`$(EXEEXT)' to each binary. Obviously it cannot rewrite values
+obtained at run-time through `configure' substitutions, therefore you
+should take care of appending `$(EXEEXT)' yourself, as in
+`AC_SUBST([MT], ['mt${EXEEXT}'])'.
+
+Conditional Programs using Automake Conditionals
+................................................
+
+You can also use Automake conditionals (*note Conditionals::) to select
+programs to be built. In this case you don't have to worry about
+`$(EXEEXT)' or `EXTRA_PROGRAMS'.
+
+ bin_PROGRAMS = cpio pax
+ if WANT_MT
+ bin_PROGRAMS += mt
+ endif
+ if WANT_RMT
+ libexec_PROGRAMS = rmt
+ endif

+
+8.2 Building a library
+======================
+
+Building a library is much like building a program. In this case, the
+name of the primary is `LIBRARIES'. Libraries can be installed in
+`libdir' or `pkglibdir'.
+
+ *Note A Shared Library::, for information on how to build shared
+libraries using libtool and the `LTLIBRARIES' primary.
+
+ Each `_LIBRARIES' variable is a list of the libraries to be built.
+For instance, to create a library named `libcpio.a', but not install
+it, you would write:
+
+ noinst_LIBRARIES = libcpio.a
+ libcpio_a_SOURCES = ...
+
+ The sources that go into a library are determined exactly as they are
+for programs, via the `_SOURCES' variables. Note that the library name
+is canonicalized (*note Canonicalization::), so the `_SOURCES' variable
+corresponding to `libcpio.a' is `libcpio_a_SOURCES', not
+`libcpio.a_SOURCES'.
+
+ Extra objects can be added to a library using the `LIBRARY_LIBADD'
+variable. This should be used for objects determined by `configure'.
+Again from `cpio':
+
+ libcpio_a_LIBADD = $(LIBOBJS) $(ALLOCA)
+
+ In addition, sources for extra objects that will not exist until
+configure-time must be added to the `BUILT_SOURCES' variable (*note
+Sources::).
+
+ Building a static library is done by compiling all object files, then
+by invoking `$(AR) $(ARFLAGS)' followed by the name of the library and
+the list of objects, and finally by calling `$(RANLIB)' on that
+library. You should call `AC_PROG_RANLIB' from your `configure.ac' to
+define `RANLIB' (Automake will complain otherwise). You should also
+call `AM_PROG_AR' to define `AR', in order to support unusual archivers
+such as Microsoft lib. `ARFLAGS' will default to `cru'; you can
+override this variable by setting it in your `Makefile.am' or by
+`AC_SUBST'ing it from your `configure.ac'. You can override the `AR'
+variable by defining a per-library `maude_AR' variable (*note Program
+and Library Variables::).
+
+ Be careful when selecting library components conditionally. Because
+building an empty library is not portable, you should ensure that any
+library always contains at least one object.

+8.3 Building a Shared Library
+=============================
+
+Building shared libraries portably is a relatively complex matter. For
+this reason, GNU Libtool (*note Introduction: (libtool)Top.) was

+
+8.3.1 The Libtool Concept
+-------------------------
+
+Libtool abstracts shared and static libraries into a unified concept
+henceforth called "libtool libraries". Libtool libraries are files
+using the `.la' suffix, and can designate a static library, a shared
+library, or maybe both. Their exact nature cannot be determined until
+`./configure' is run: not all platforms support all kinds of libraries,
+and users can explicitly select which libraries should be built.
+(However the package's maintainers can tune the default, *note The
+`AC_PROG_LIBTOOL' macro: (libtool)AC_PROG_LIBTOOL.)
+
+ Because object files for shared and static libraries must be compiled
+differently, libtool is also used during compilation. Object files
+built by libtool are called "libtool objects": these are files using
+the `.lo' suffix. Libtool libraries are built from these libtool
+objects.
+
+ You should not assume anything about the structure of `.la' or `.lo'
+files and how libtool constructs them: this is libtool's concern, and
+the last thing one wants is to learn about libtool's guts. However the
+existence of these files matters, because they are used as targets and
+dependencies in `Makefile's rules when building libtool libraries.
+There are situations where you may have to refer to these, for instance
+when expressing dependencies for building source files conditionally
+(*note Conditional Libtool Sources::).
+
+ People considering writing a plug-in system, with dynamically loaded
+modules, should look into `libltdl': libtool's dlopening library (*note
+Using libltdl: (libtool)Using libltdl.). This offers a portable
+dlopening facility to load libtool libraries dynamically, and can also
+achieve static linking where unavoidable.
+
+ Before we discuss how to use libtool with Automake in details, it
+should be noted that the libtool manual also has a section about how to
+use Automake with libtool (*note Using Automake with Libtool:
+(libtool)Using Automake.).
+
+\1f
+File: automake.info, Node: Libtool Libraries, Next: Conditional Libtool Libraries, Prev: Libtool Concept, Up: A Shared Library
+
+8.3.2 Building Libtool Libraries
+--------------------------------
+
+Automake uses libtool to build libraries declared with the
+`LTLIBRARIES' primary. Each `_LTLIBRARIES' variable is a list of
+libtool libraries to build. For instance, to create a libtool library
+named `libgettext.la', and install it in `libdir', write:
+
+ lib_LTLIBRARIES = libgettext.la
+ libgettext_la_SOURCES = gettext.c gettext.h ...
+
+ Automake predefines the variable `pkglibdir', so you can use
+`pkglib_LTLIBRARIES' to install libraries in `$(libdir)/@PACKAGE@/'.
+
+ If `gettext.h' is a public header file that needs to be installed in
+order for people to use the library, it should be declared using a
+`_HEADERS' variable, not in `libgettext_la_SOURCES'. Headers listed in
+the latter should be internal headers that are not part of the public
+interface.
+
+ lib_LTLIBRARIES = libgettext.la
+ libgettext_la_SOURCES = gettext.c ...
+ include_HEADERS = gettext.h ...
+
+ A package can build and install such a library along with other
+programs that use it. This dependency should be specified using
+`LDADD'. The following example builds a program named `hello' that is
+linked with `libgettext.la'.
+
+ lib_LTLIBRARIES = libgettext.la
+ libgettext_la_SOURCES = gettext.c ...
+
+ bin_PROGRAMS = hello
+ hello_SOURCES = hello.c ...
+ hello_LDADD = libgettext.la
+
+Whether `hello' is statically or dynamically linked with
+`libgettext.la' is not yet known: this will depend on the configuration
+of libtool and the capabilities of the host.
+

+
+8.3.3 Building Libtool Libraries Conditionally
+----------------------------------------------
+
+Like conditional programs (*note Conditional Programs::), there are two
+main ways to build conditional libraries: using Automake conditionals
+or using Autoconf `AC_SUBST'itutions.
+
+ The important implementation detail you have to be aware of is that
+the place where a library will be installed matters to libtool: it
+needs to be indicated _at link-time_ using the `-rpath' option.
+
+ For libraries whose destination directory is known when Automake
+runs, Automake will automatically supply the appropriate `-rpath'
+option to libtool. This is the case for libraries listed explicitly in
+some installable `_LTLIBRARIES' variables such as `lib_LTLIBRARIES'.
+
+ However, for libraries determined at configure time (and thus
+mentioned in `EXTRA_LTLIBRARIES'), Automake does not know the final
+installation directory. For such libraries you must add the `-rpath'
+option to the appropriate `_LDFLAGS' variable by hand.
+
+ The examples below illustrate the differences between these two
+methods.
+
+ Here is an example where `WANTEDLIBS' is an `AC_SUBST'ed variable
+set at `./configure'-time to either `libfoo.la', `libbar.la', both, or
+none. Although `$(WANTEDLIBS)' appears in the `lib_LTLIBRARIES',
+Automake cannot guess it relates to `libfoo.la' or `libbar.la' at the
+time it creates the link rule for these two libraries. Therefore the
+`-rpath' argument must be explicitly supplied.
+
+ EXTRA_LTLIBRARIES = libfoo.la libbar.la
+ lib_LTLIBRARIES = $(WANTEDLIBS)
+ libfoo_la_SOURCES = foo.c ...
+ libfoo_la_LDFLAGS = -rpath '$(libdir)'
+ libbar_la_SOURCES = bar.c ...
+ libbar_la_LDFLAGS = -rpath '$(libdir)'
+
+ Here is how the same `Makefile.am' would look using Automake
+conditionals named `WANT_LIBFOO' and `WANT_LIBBAR'. Now Automake is
+able to compute the `-rpath' setting itself, because it's clear that
+both libraries will end up in `$(libdir)' if they are installed.
+
+ lib_LTLIBRARIES =
+ if WANT_LIBFOO
+ lib_LTLIBRARIES += libfoo.la
+ endif
+ if WANT_LIBBAR
+ lib_LTLIBRARIES += libbar.la
+ endif
+ libfoo_la_SOURCES = foo.c ...
+ libbar_la_SOURCES = bar.c ...
+

+
+8.3.4 Libtool Libraries with Conditional Sources
+------------------------------------------------
+
+Conditional compilation of sources in a library can be achieved in the
+same way as conditional compilation of sources in a program (*note
+Conditional Sources::). The only difference is that `_LIBADD' should
+be used instead of `_LDADD' and that it should mention libtool objects
+(`.lo' files).
+
+ So, to mimic the `hello' example from *note Conditional Sources::,
+we could build a `libhello.la' library using either `hello-linux.c' or
+`hello-generic.c' with the following `Makefile.am'.
+
+ lib_LTLIBRARIES = libhello.la
+ libhello_la_SOURCES = hello-common.c
+ EXTRA_libhello_la_SOURCES = hello-linux.c hello-generic.c
+ libhello_la_LIBADD = $(HELLO_SYSTEM)
+ libhello_la_DEPENDENCIES = $(HELLO_SYSTEM)
+
+And make sure `configure' defines `HELLO_SYSTEM' as either
+`hello-linux.lo' or `hello-generic.lo'.
+
+ Or we could simply use an Automake conditional as follows.
+
+ lib_LTLIBRARIES = libhello.la
+ libhello_la_SOURCES = hello-common.c
+ if LINUX
+ libhello_la_SOURCES += hello-linux.c
+ else
+ libhello_la_SOURCES += hello-generic.c
+ endif

+
+8.3.5 Libtool Convenience Libraries
+-----------------------------------
+
+Sometimes you want to build libtool libraries that should not be
+installed. These are called "libtool convenience libraries" and are
+typically used to encapsulate many sublibraries, later gathered into
+one big installed library.
+
+ Libtool convenience libraries are declared by directory-less
+variables such as `noinst_LTLIBRARIES', `check_LTLIBRARIES', or even
+`EXTRA_LTLIBRARIES'. Unlike installed libtool libraries they do not
+need an `-rpath' flag at link time (actually this is the only
+difference).
+
+ Convenience libraries listed in `noinst_LTLIBRARIES' are always
+built. Those listed in `check_LTLIBRARIES' are built only upon `make
+check'. Finally, libraries listed in `EXTRA_LTLIBRARIES' are never
+built explicitly: Automake outputs rules to build them, but if the
+library does not appear as a Makefile dependency anywhere it won't be
+built (this is why `EXTRA_LTLIBRARIES' is used for conditional
+compilation).
+
+ Here is a sample setup merging libtool convenience libraries from
+subdirectories into one main `libtop.la' library.
+
+ # -- Top-level Makefile.am --
+ SUBDIRS = sub1 sub2 ...
+ lib_LTLIBRARIES = libtop.la
+ libtop_la_SOURCES =
+ libtop_la_LIBADD = \
+ sub1/libsub1.la \
+ sub2/libsub2.la \
+ ...
+
+ # -- sub1/Makefile.am --
+ noinst_LTLIBRARIES = libsub1.la
+ libsub1_la_SOURCES = ...
+
+ # -- sub2/Makefile.am --
+ # showing nested convenience libraries
+ SUBDIRS = sub2.1 sub2.2 ...
+ noinst_LTLIBRARIES = libsub2.la
+ libsub2_la_SOURCES =
+ libsub2_la_LIBADD = \
+ sub21/libsub21.la \
+ sub22/libsub22.la \
+ ...
+
+ When using such setup, beware that `automake' will assume
+`libtop.la' is to be linked with the C linker. This is because
+`libtop_la_SOURCES' is empty, so `automake' picks C as default
+language. If `libtop_la_SOURCES' was not empty, `automake' would
+select the linker as explained in *note How the Linker is Chosen::.
+
+ If one of the sublibraries contains non-C source, it is important
+that the appropriate linker be chosen. One way to achieve this is to
+pretend that there is such a non-C file among the sources of the
+library, thus forcing `automake' to select the appropriate linker.
+Here is the top-level `Makefile' of our example updated to force C++
+linking.
+
+ SUBDIRS = sub1 sub2 ...
+ lib_LTLIBRARIES = libtop.la
+ libtop_la_SOURCES =
+ # Dummy C++ source to cause C++ linking.
+ nodist_EXTRA_libtop_la_SOURCES = dummy.cxx
+ libtop_la_LIBADD = \
+ sub1/libsub1.la \
+ sub2/libsub2.la \
+ ...
+
+ `EXTRA_*_SOURCES' variables are used to keep track of source files
+that might be compiled (this is mostly useful when doing conditional
+compilation using `AC_SUBST', *note Conditional Libtool Sources::), and
+the `nodist_' prefix means the listed sources are not to be distributed
+(*note Program and Library Variables::). In effect the file
+`dummy.cxx' does not need to exist in the source tree. Of course if
+you have some real source file to list in `libtop_la_SOURCES' there is
+no point in cheating with `nodist_EXTRA_libtop_la_SOURCES'.
+

+
+8.3.6 Libtool Modules
+---------------------
+
+These are libtool libraries meant to be dlopened. They are indicated
+to libtool by passing `-module' at link-time.
+
+ pkglib_LTLIBRARIES = mymodule.la
+ mymodule_la_SOURCES = doit.c
+ mymodule_la_LDFLAGS = -module
+
+ Ordinarily, Automake requires that a library's name start with
+`lib'. However, when building a dynamically loadable module you might
+wish to use a "nonstandard" name. Automake will not complain about
+such nonstandard names if it knows the library being built is a libtool
+module, i.e., if `-module' explicitly appears in the library's
+`_LDFLAGS' variable (or in the common `AM_LDFLAGS' variable when no
+per-library `_LDFLAGS' variable is defined).
+
+ As always, `AC_SUBST' variables are black boxes to Automake since
+their values are not yet known when `automake' is run. Therefore if
+`-module' is set via such a variable, Automake cannot notice it and
+will proceed as if the library was an ordinary libtool library, with
+strict naming.
+
+ If `mymodule_la_SOURCES' is not specified, then it defaults to the
+single file `mymodule.c' (*note Default _SOURCES::).
+

+
+8.3.7 `_LIBADD', `_LDFLAGS', and `_LIBTOOLFLAGS'
+------------------------------------------------
+
+As shown in previous sections, the `LIBRARY_LIBADD' variable should be
+used to list extra libtool objects (`.lo' files) or libtool libraries
+(`.la') to add to LIBRARY.
+
+ The `LIBRARY_LDFLAGS' variable is the place to list additional
+libtool linking flags, such as `-version-info', `-static', and a lot
+more. *Note Link mode: (libtool)Link mode.
+
+ The `libtool' command has two kinds of options: mode-specific
+options and generic options. Mode-specific options such as the
+aforementioned linking flags should be lumped with the other flags
+passed to the tool invoked by `libtool' (hence the use of
+`LIBRARY_LDFLAGS' for libtool linking flags). Generic options include
+`--tag=TAG' and `--silent' (*note Invoking `libtool': (libtool)Invoking
+libtool. for more options) should appear before the mode selection on
+the command line; in `Makefile.am's they should be listed in the
+`LIBRARY_LIBTOOLFLAGS' variable.
+
+ If `LIBRARY_LIBTOOLFLAGS' is not defined, then the variable
+`AM_LIBTOOLFLAGS' is used instead.
+
+ These flags are passed to libtool after the `--tag=TAG' option
+computed by Automake (if any), so `LIBRARY_LIBTOOLFLAGS' (or
+`AM_LIBTOOLFLAGS') is a good place to override or supplement the
+`--tag=TAG' setting.
+
+ The libtool rules also use a `LIBTOOLFLAGS' variable that should not
+be set in `Makefile.am': this is a user variable (*note Flag Variables
+Ordering::. It allows users to run `make LIBTOOLFLAGS=--silent', for
+instance. Note that the verbosity of `libtool' can also be influenced
+with the Automake `silent-rules' option (*note Options::).

+8.3.8 `LTLIBOBJS' and `LTALLOCA'
+--------------------------------
+
+Where an ordinary library might include `$(LIBOBJS)' or `$(ALLOCA)'
+(*note LIBOBJS::), a libtool library must use `$(LTLIBOBJS)' or
+`$(LTALLOCA)'. This is required because the object files that libtool
+operates on do not necessarily end in `.o'.
+
+ Nowadays, the computation of `LTLIBOBJS' from `LIBOBJS' is performed
+automatically by Autoconf (*note `AC_LIBOBJ' vs. `LIBOBJS':

+8.3.9.1 Error: `required file `./ltmain.sh' not found'
+......................................................
+
+Libtool comes with a tool called `libtoolize' that will install
+libtool's supporting files into a package. Running this command will
+install `ltmain.sh'. You should execute it before `aclocal' and
+`automake'.
+
+ People upgrading old packages to newer autotools are likely to face
+this issue because older Automake versions used to call `libtoolize'.
+Therefore old build scripts do not call `libtoolize'.
+
+ Since Automake 1.6, it has been decided that running `libtoolize'
+was none of Automake's business. Instead, that functionality has been
+moved into the `autoreconf' command (*note Using `autoreconf':
+(autoconf)autoreconf Invocation.). If you do not want to remember what
+to run and when, just learn the `autoreconf' command. Hopefully,
+replacing existing `bootstrap.sh' or `autogen.sh' scripts by a call to
+`autoreconf' should also free you from any similar incompatible change
+in the future.

+
+8.3.9.2 Objects `created with both libtool and without'
+.......................................................
+
+Sometimes, the same source file is used both to build a libtool library
+and to build another non-libtool target (be it a program or another
+library).
+
+ Let's consider the following `Makefile.am'.
+
+ bin_PROGRAMS = prog
+ prog_SOURCES = prog.c foo.c ...
+
+ lib_LTLIBRARIES = libfoo.la
+ libfoo_la_SOURCES = foo.c ...
+
+(In this trivial case the issue could be avoided by linking `libfoo.la'
+with `prog' instead of listing `foo.c' in `prog_SOURCES'. But let's
+assume we really want to keep `prog' and `libfoo.la' separate.)
+
+ Technically, it means that we should build `foo.$(OBJEXT)' for
+`prog', and `foo.lo' for `libfoo.la'. The problem is that in the
+course of creating `foo.lo', libtool may erase (or replace)
+`foo.$(OBJEXT)', and this cannot be avoided.
+
+ Therefore, when Automake detects this situation it will complain
+with a message such as
+ object `foo.$(OBJEXT)' created both with libtool and without
+
+ A workaround for this issue is to ensure that these two objects get
+different basenames. As explained in *note Renamed Objects::, this
+happens automatically when per-targets flags are used.
+
+ bin_PROGRAMS = prog
+ prog_SOURCES = prog.c foo.c ...
+ prog_CFLAGS = $(AM_CFLAGS)
+
+ lib_LTLIBRARIES = libfoo.la
+ libfoo_la_SOURCES = foo.c ...
+
+Adding `prog_CFLAGS = $(AM_CFLAGS)' is almost a no-op, because when the
+`prog_CFLAGS' is defined, it is used instead of `AM_CFLAGS'. However
+as a side effect it will cause `prog.c' and `foo.c' to be compiled as
+`prog-prog.$(OBJEXT)' and `prog-foo.$(OBJEXT)', which solves the issue.

+
+8.4 Program and Library Variables
+=================================
+
+Associated with each program is a collection of variables that can be
+used to modify how that program is built. There is a similar list of
+such variables for each library. The canonical name of the program (or
+library) is used as a base for naming these variables.
+
+ In the list below, we use the name "maude" to refer to the program or
+library. In your `Makefile.am' you would replace this with the
+canonical name of your program. This list also refers to "maude" as a
+program, but in general the same rules apply for both static and dynamic
+libraries; the documentation below notes situations where programs and
+libraries differ.
+
+`maude_SOURCES'
+ This variable, if it exists, lists all the source files that are
+ compiled to build the program. These files are added to the
+ distribution by default. When building the program, Automake will
+ cause each source file to be compiled to a single `.o' file (or
+ `.lo' when using libtool). Normally these object files are named
+ after the source file, but other factors can change this. If a
+ file in the `_SOURCES' variable has an unrecognized extension,
+ Automake will do one of two things with it. If a suffix rule
+ exists for turning files with the unrecognized extension into `.o'
+ files, then `automake' will treat this file as it will any other
+ source file (*note Support for Other Languages::). Otherwise, the
+ file will be ignored as though it were a header file.
+
+ The prefixes `dist_' and `nodist_' can be used to control whether
+ files listed in a `_SOURCES' variable are distributed. `dist_' is
+ redundant, as sources are distributed by default, but it can be
+ specified for clarity if desired.
+
+ It is possible to have both `dist_' and `nodist_' variants of a
+ given `_SOURCES' variable at once; this lets you easily distribute
+ some files and not others, for instance:
+
+ nodist_maude_SOURCES = nodist.c
+ dist_maude_SOURCES = dist-me.c
+
+ By default the output file (on Unix systems, the `.o' file) will
+ be put into the current build directory. However, if the option
+ `subdir-objects' is in effect in the current directory then the
+ `.o' file will be put into the subdirectory named after the source
+ file. For instance, with `subdir-objects' enabled,
+ `sub/dir/file.c' will be compiled to `sub/dir/file.o'. Some
+ people prefer this mode of operation. You can specify
+ `subdir-objects' in `AUTOMAKE_OPTIONS' (*note Options::).
+
+`EXTRA_maude_SOURCES'
+ Automake needs to know the list of files you intend to compile
+ _statically_. For one thing, this is the only way Automake has of
+ knowing what sort of language support a given `Makefile.in'
+ requires. (1) This means that, for example, you can't put a
+ configure substitution like `@my_sources@' into a `_SOURCES'
+ variable. If you intend to conditionally compile source files and
+ use `configure' to substitute the appropriate object names into,
+ e.g., `_LDADD' (see below), then you should list the corresponding
+ source files in the `EXTRA_' variable.
+
+ This variable also supports `dist_' and `nodist_' prefixes. For
+ instance, `nodist_EXTRA_maude_SOURCES' would list extra sources
+ that may need to be built, but should not be distributed.
+
+`maude_AR'
+ A static library is created by default by invoking `$(AR)
+ $(ARFLAGS)' followed by the name of the library and then the
+ objects being put into the library. You can override this by
+ setting the `_AR' variable. This is usually used with C++; some
+ C++ compilers require a special invocation in order to instantiate
+ all the templates that should go into a library. For instance,
+ the SGI C++ compiler likes this variable set like so:
+ libmaude_a_AR = $(CXX) -ar -o
+
+`maude_LIBADD'
+ Extra objects can be added to a _library_ using the `_LIBADD'
+ variable. For instance, this should be used for objects
+ determined by `configure' (*note A Library::).
+
+ In the case of libtool libraries, `maude_LIBADD' can also refer to
+ other libtool libraries.
+
+`maude_LDADD'
+ Extra objects (`*.$(OBJEXT)') and libraries (`*.a', `*.la') can be
+ added to a _program_ by listing them in the `_LDADD' variable.
+ For instance, this should be used for objects determined by
+ `configure' (*note Linking::).
+
+ `_LDADD' and `_LIBADD' are inappropriate for passing
+ program-specific linker flags (except for `-l', `-L', `-dlopen'
+ and `-dlpreopen'). Use the `_LDFLAGS' variable for this purpose.
+
+ For instance, if your `configure.ac' uses `AC_PATH_XTRA', you
+ could link your program against the X libraries like so:
+
+ maude_LDADD = $(X_PRE_LIBS) $(X_LIBS) $(X_EXTRA_LIBS)
+
+ We recommend that you use `-l' and `-L' only when referring to
+ third-party libraries, and give the explicit file names of any
+ library built by your package. Doing so will ensure that
+ `maude_DEPENDENCIES' (see below) is correctly defined by default.
+
+`maude_LDFLAGS'
+ This variable is used to pass extra flags to the link step of a
+ program or a shared library. It overrides the `AM_LDFLAGS'
+ variable.
+
+`maude_LIBTOOLFLAGS'
+ This variable is used to pass extra options to `libtool'. It
+ overrides the `AM_LIBTOOLFLAGS' variable. These options are
+ output before `libtool''s `--mode=MODE' option, so they should not
+ be mode-specific options (those belong to the compiler or linker
+ flags). *Note Libtool Flags::.
+
+`maude_DEPENDENCIES'
+`EXTRA_maude_DEPENDENCIES'
+ It is also occasionally useful to have a target (program or
+ library) depend on some other file that is not actually part of
+ that target. This can be done using the `_DEPENDENCIES' variable.
+ Each target depends on the contents of such a variable, but no
+ further interpretation is done.
+
+ Since these dependencies are associated to the link rule used to
+ create the programs they should normally list files used by the
+ link command. That is `*.$(OBJEXT)', `*.a', or `*.la' files for
+ programs; `*.lo' and `*.la' files for Libtool libraries; and
+ `*.$(OBJEXT)' files for static libraries. In rare cases you may
+ need to add other kinds of files such as linker scripts, but
+ _listing a source file in `_DEPENDENCIES' is wrong_. If some
+ source file needs to be built before all the components of a
+ program are built, consider using the `BUILT_SOURCES' variable
+ (*note Sources::).
+
+ If `_DEPENDENCIES' is not supplied, it is computed by Automake.
+ The automatically-assigned value is the contents of `_LDADD' or
+ `_LIBADD', with most configure substitutions, `-l', `-L',
+ `-dlopen' and `-dlpreopen' options removed. The configure
+ substitutions that are left in are only `$(LIBOBJS)' and
+ `$(ALLOCA)'; these are left because it is known that they will not
+ cause an invalid value for `_DEPENDENCIES' to be generated.
+
+ `_DEPENDENCIES' is more likely used to perform conditional
+ compilation using an `AC_SUBST' variable that contains a list of
+ objects. *Note Conditional Sources::, and *note Conditional
+ Libtool Sources::.
+
+ The `EXTRA_*_DEPENDENCIES' variable may be useful for cases where
+ you merely want to augment the `automake'-generated
+ `_DEPENDENCIES' variable rather than replacing it.
+
+`maude_LINK'
+ You can override the linker on a per-program basis. By default the
+ linker is chosen according to the languages used by the program.
+ For instance, a program that includes C++ source code would use
+ the C++ compiler to link. The `_LINK' variable must hold the name
+ of a command that can be passed all the `.o' file names and
+ libraries to link against as arguments. Note that the name of the
+ underlying program is _not_ passed to `_LINK'; typically one uses
+ `$@':
+
+ maude_LINK = $(CCLD) -magic -o $@
+
+ If a `_LINK' variable is not supplied, it may still be generated
+ and used by Automake due to the use of per-target link flags such
+ as `_CFLAGS', `_LDFLAGS' or `_LIBTOOLFLAGS', in cases where they
+ apply.
+
+`maude_CCASFLAGS'
+`maude_CFLAGS'
+`maude_CPPFLAGS'
+`maude_CXXFLAGS'
+`maude_FFLAGS'
+`maude_GCJFLAGS'
+`maude_LFLAGS'
+`maude_OBJCFLAGS'
+`maude_OBJCXXFLAGS'
+`maude_RFLAGS'
+`maude_UPCFLAGS'
+`maude_YFLAGS'
+ Automake allows you to set compilation flags on a per-program (or
+ per-library) basis. A single source file can be included in
+ several programs, and it will potentially be compiled with
+ different flags for each program. This works for any language
+ directly supported by Automake. These "per-target compilation
+ flags" are `_CCASFLAGS', `_CFLAGS', `_CPPFLAGS', `_CXXFLAGS',
+ `_FFLAGS', `_GCJFLAGS', `_LFLAGS', `_OBJCFLAGS', `_OBJCXXFLAGS',
+ `_RFLAGS', `_UPCFLAGS', and `_YFLAGS'.
+
+ When using a per-target compilation flag, Automake will choose a
+ different name for the intermediate object files. Ordinarily a
+ file like `sample.c' will be compiled to produce `sample.o'.
+ However, if the program's `_CFLAGS' variable is set, then the
+ object file will be named, for instance, `maude-sample.o'. (See
+ also *note Renamed Objects::.) The use of per-target compilation
+ flags with C sources requires that the macro `AM_PROG_CC_C_O' be
+ called from `configure.ac'.
+
+ In compilations with per-target flags, the ordinary `AM_' form of
+ the flags variable is _not_ automatically included in the
+ compilation (however, the user form of the variable _is_ included).
+ So for instance, if you want the hypothetical `maude' compilations
+ to also use the value of `AM_CFLAGS', you would need to write:
+
+ maude_CFLAGS = ... your flags ... $(AM_CFLAGS)
+
+ *Note Flag Variables Ordering::, for more discussion about the
+ interaction between user variables, `AM_' shadow variables, and
+ per-target variables.
+
+`maude_SHORTNAME'
+ On some platforms the allowable file names are very short. In
+ order to support these systems and per-target compilation flags at
+ the same time, Automake allows you to set a "short name" that will
+ influence how intermediate object files are named. For instance,
+ in the following example,
+
+ bin_PROGRAMS = maude
+ maude_CPPFLAGS = -DSOMEFLAG
+ maude_SHORTNAME = m
+ maude_SOURCES = sample.c ...
+
+ the object file would be named `m-sample.o' rather than
+ `maude-sample.o'.
+
+ This facility is rarely needed in practice, and we recommend
+ avoiding it until you find it is required.

+
+8.5 Default `_SOURCES'
+======================
+
+`_SOURCES' variables are used to specify source files of programs
+(*note A Program::), libraries (*note A Library::), and Libtool
+libraries (*note A Shared Library::).
+
+ When no such variable is specified for a target, Automake will define
+one itself. The default is to compile a single C file whose base name
+is the name of the target itself, with any extension replaced by
+`AM_DEFAULT_SOURCE_EXT', which defaults to `.c'.
+
+ For example if you have the following somewhere in your
+`Makefile.am' with no corresponding `libfoo_a_SOURCES':
+
+ lib_LIBRARIES = libfoo.a sub/libc++.a
+
+`libfoo.a' will be built using a default source file named `libfoo.c',
+and `sub/libc++.a' will be built from `sub/libc++.c'. (In older
+versions `sub/libc++.a' would be built from `sub_libc___a.c', i.e., the
+default source was the canonized name of the target, with `.c' appended.
+We believe the new behavior is more sensible, but for backward
+compatibility `automake' will use the old name if a file or a rule with
+that name exists and `AM_DEFAULT_SOURCE_EXT' is not used.)
+
+ Default sources are mainly useful in test suites, when building many
+test programs each from a single source. For instance, in
+
+ check_PROGRAMS = test1 test2 test3
+ AM_DEFAULT_SOURCE_EXT = .cpp
+
+`test1', `test2', and `test3' will be built from `test1.cpp',
+`test2.cpp', and `test3.cpp'. Without the last line, they will be
+built from `test1.c', `test2.c', and `test3.c'.
+
+ Another case where this is convenient is building many Libtool
+modules (`moduleN.la'), each defined in its own file (`moduleN.c').
+
+ AM_LDFLAGS = -module
+ lib_LTLIBRARIES = module1.la module2.la module3.la
+
+ Finally, there is one situation where this default source computation
+needs to be avoided: when a target should not be built from sources.
+We already saw such an example in *note true::; this happens when all
+the constituents of a target have already been compiled and just need
+to be combined using a `_LDADD' variable. Then it is necessary to
+define an empty `_SOURCES' variable, so that `automake' does not
+compute a default.
+
+ bin_PROGRAMS = target
+ target_SOURCES =
+ target_LDADD = libmain.a libmisc.a

+
+8.6 Special handling for `LIBOBJS' and `ALLOCA'
+===============================================
+
+The `$(LIBOBJS)' and `$(ALLOCA)' variables list object files that
+should be compiled into the project to provide an implementation for
+functions that are missing or broken on the host system. They are
+substituted by `configure'.
+
+ These variables are defined by Autoconf macros such as `AC_LIBOBJ',
+`AC_REPLACE_FUNCS' (*note Generic Function Checks: (autoconf)Generic
+Functions.), or `AC_FUNC_ALLOCA' (*note Particular Function Checks:
+(autoconf)Particular Functions.). Many other Autoconf macros call
+`AC_LIBOBJ' or `AC_REPLACE_FUNCS' to populate `$(LIBOBJS)'.
+
+ Using these variables is very similar to doing conditional
+compilation using `AC_SUBST' variables, as described in *note
+Conditional Sources::. That is, when building a program, `$(LIBOBJS)'
+and `$(ALLOCA)' should be added to the associated `*_LDADD' variable,
+or to the `*_LIBADD' variable when building a library. However there
+is no need to list the corresponding sources in `EXTRA_*_SOURCES' nor
+to define `*_DEPENDENCIES'. Automake automatically adds `$(LIBOBJS)'
+and `$(ALLOCA)' to the dependencies, and it will discover the list of
+corresponding source files automatically (by tracing the invocations of
+the `AC_LIBSOURCE' Autoconf macros). If you have already defined
+`*_DEPENDENCIES' explicitly for an unrelated reason, then you either
+need to add these variables manually, or use `EXTRA_*_DEPENDENCIES'
+instead of `*_DEPENDENCIES'.
+
+ These variables are usually used to build a portability library that
+is linked with all the programs of the project. We now review a sample
+setup. First, `configure.ac' contains some checks that affect either
+`LIBOBJS' or `ALLOCA'.
+
+ # configure.ac
+ ...
+ AC_CONFIG_LIBOBJ_DIR([lib])
+ ...
+ AC_FUNC_MALLOC dnl May add malloc.$(OBJEXT) to LIBOBJS
+ AC_FUNC_MEMCMP dnl May add memcmp.$(OBJEXT) to LIBOBJS
+ AC_REPLACE_FUNCS([strdup]) dnl May add strdup.$(OBJEXT) to LIBOBJS
+ AC_FUNC_ALLOCA dnl May add alloca.$(OBJEXT) to ALLOCA
+ ...
+ AC_CONFIG_FILES([
+ lib/Makefile
+ src/Makefile
+ ])
+ AC_OUTPUT
+
+ The `AC_CONFIG_LIBOBJ_DIR' tells Autoconf that the source files of
+these object files are to be found in the `lib/' directory. Automake
+can also use this information, otherwise it expects the source files
+are to be in the directory where the `$(LIBOBJS)' and `$(ALLOCA)'
+variables are used.
+
+ The `lib/' directory should therefore contain `malloc.c',
+`memcmp.c', `strdup.c', `alloca.c'. Here is its `Makefile.am':
+
+ # lib/Makefile.am
+
+ noinst_LIBRARIES = libcompat.a
+ libcompat_a_SOURCES =
+ libcompat_a_LIBADD = $(LIBOBJS) $(ALLOCA)
+
+ The library can have any name, of course, and anyway it is not going
+to be installed: it just holds the replacement versions of the missing
+or broken functions so we can later link them in. Many projects also
+include extra functions, specific to the project, in that library: they
+are simply added on the `_SOURCES' line.
+
+ There is a small trap here, though: `$(LIBOBJS)' and `$(ALLOCA)'
+might be empty, and building an empty library is not portable. You
+should ensure that there is always something to put in `libcompat.a'.
+Most projects will also add some utility functions in that directory,
+and list them in `libcompat_a_SOURCES', so in practice `libcompat.a'
+cannot be empty.
+
+ Finally here is how this library could be used from the `src/'
+directory.
+
+ # src/Makefile.am
+
+ # Link all programs in this directory with libcompat.a
+ LDADD = ../lib/libcompat.a
+
+ bin_PROGRAMS = tool1 tool2 ...
+ tool1_SOURCES = ...
+ tool2_SOURCES = ...
+
+ When option `subdir-objects' is not used, as in the above example,
+the variables `$(LIBOBJS)' or `$(ALLOCA)' can only be used in the
+directory where their sources lie. E.g., here it would be wrong to use
+`$(LIBOBJS)' or `$(ALLOCA)' in `src/Makefile.am'. However if both
+`subdir-objects' and `AC_CONFIG_LIBOBJ_DIR' are used, it is OK to use
+these variables in other directories. For instance `src/Makefile.am'
+could be changed as follows.
+
+ # src/Makefile.am
+
+ AUTOMAKE_OPTIONS = subdir-objects
+ LDADD = $(LIBOBJS) $(ALLOCA)
+
+ bin_PROGRAMS = tool1 tool2 ...
+ tool1_SOURCES = ...
+ tool2_SOURCES = ...
+
+ Because `$(LIBOBJS)' and `$(ALLOCA)' contain object file names that
+end with `.$(OBJEXT)', they are not suitable for Libtool libraries
+(where the expected object extension is `.lo'): `LTLIBOBJS' and
+`LTALLOCA' should be used instead.
+
+ `LTLIBOBJS' is defined automatically by Autoconf and should not be
+defined by hand (as in the past), however at the time of writing
+`LTALLOCA' still needs to be defined from `ALLOCA' manually. *Note
+`AC_LIBOBJ' vs. `LIBOBJS': (autoconf)AC_LIBOBJ vs LIBOBJS.

+
+8.7 Variables used when building a program
+==========================================
+
+Occasionally it is useful to know which `Makefile' variables Automake
+uses for compilations, and in which order (*note Flag Variables
+Ordering::); for instance, you might need to do your own compilation in
+some special cases.
+
+ Some variables are inherited from Autoconf; these are `CC',
+`CFLAGS', `CPPFLAGS', `DEFS', `LDFLAGS', and `LIBS'.
+
+ There are some additional variables that Automake defines on its own:
+
+`AM_CPPFLAGS'
+ The contents of this variable are passed to every compilation that
+ invokes the C preprocessor; it is a list of arguments to the
+ preprocessor. For instance, `-I' and `-D' options should be
+ listed here.
+
+ Automake already provides some `-I' options automatically, in a
+ separate variable that is also passed to every compilation that
+ invokes the C preprocessor. In particular it generates `-I.',
+ `-I$(srcdir)', and a `-I' pointing to the directory holding
+ `config.h' (if you've used `AC_CONFIG_HEADERS' or
+ `AM_CONFIG_HEADER'). You can disable the default `-I' options
+ using the `nostdinc' option.
+
+ When a file to be included is generated during the build and not
+ part of a distribution tarball, its location is under
+ `$(builddir)', not under `$(srcdir)'. This matters especially for
+ packages that use header files placed in sub-directories and want
+ to allow builds outside the source tree (*note VPATH Builds::). In
+ that case we recommend to use a pair of `-I' options, such as,
+ e.g., `-Isome/subdir -I$(srcdir)/some/subdir' or
+ `-I$(top_builddir)/some/subdir -I$(top_srcdir)/some/subdir'. Note
+ that the reference to the build tree should come before the
+ reference to the source tree, so that accidentally leftover
+ generated files in the source directory are ignored.
+
+ `AM_CPPFLAGS' is ignored in preference to a per-executable (or
+ per-library) `_CPPFLAGS' variable if it is defined.
+
+`INCLUDES'
+ This does the same job as `AM_CPPFLAGS' (or any per-target
+ `_CPPFLAGS' variable if it is used). It is an older name for the
+ same functionality. This variable is deprecated; we suggest using
+ `AM_CPPFLAGS' and per-target `_CPPFLAGS' instead.
+
+`AM_CFLAGS'
+ This is the variable the `Makefile.am' author can use to pass in
+ additional C compiler flags. It is more fully documented
+ elsewhere. In some situations, this is not used, in preference to
+ the per-executable (or per-library) `_CFLAGS'.
+
+`COMPILE'
+ This is the command used to actually compile a C source file. The
+ file name is appended to form the complete command line.
+
+`AM_LDFLAGS'
+ This is the variable the `Makefile.am' author can use to pass in
+ additional linker flags. In some situations, this is not used, in
+ preference to the per-executable (or per-library) `_LDFLAGS'.
+
+`LINK'
+ This is the command used to actually link a C program. It already
+ includes `-o $@' and the usual variable references (for instance,
+ `CFLAGS'); it takes as "arguments" the names of the object files
+ and libraries to link in. This variable is not used when the
+ linker is overridden with a per-target `_LINK' variable or
+ per-target flags cause Automake to define such a `_LINK' variable.
+
+\1f
+File: automake.info, Node: Yacc and Lex, Next: C++ Support, Prev: Program Variables, Up: Programs
+
+8.8 Yacc and Lex support
+========================
+
+Automake has somewhat idiosyncratic support for Yacc and Lex.
+
+ Automake assumes that the `.c' file generated by `yacc' (or `lex')
+should be named using the basename of the input file. That is, for a
+yacc source file `foo.y', Automake will cause the intermediate file to
+be named `foo.c' (as opposed to `y.tab.c', which is more traditional).
+
+ The extension of a yacc source file is used to determine the
+extension of the resulting C or C++ source and header files. Note that
+header files are generated only when the `-d' Yacc option is used; see
+below for more information about this flag, and how to specify it.
+Files with the extension `.y' will thus be turned into `.c' sources and
+`.h' headers; likewise, `.yy' will become `.cc' and `.hh', `.y++' will
+become `c++' and `h++', `.yxx' will become `.cxx' and `.hxx', and
+`.ypp' will become `.cpp' and `.hpp'.
+
+ Similarly, lex source files can be used to generate C or C++; the
+extensions `.l', `.ll', `.l++', `.lxx', and `.lpp' are recognized.
+
+ You should never explicitly mention the intermediate (C or C++) file
+in any `SOURCES' variable; only list the source file.
+
+ The intermediate files generated by `yacc' (or `lex') will be
+included in any distribution that is made. That way the user doesn't
+need to have `yacc' or `lex'.
+
+ If a `yacc' source file is seen, then your `configure.ac' must
+define the variable `YACC'. This is most easily done by invoking the
+macro `AC_PROG_YACC' (*note Particular Program Checks:
+(autoconf)Particular Programs.).
+
+ When `yacc' is invoked, it is passed `AM_YFLAGS' and `YFLAGS'. The
+latter is a user variable and the former is intended for the
+`Makefile.am' author.
+
+ `AM_YFLAGS' is usually used to pass the `-d' option to `yacc'.
+Automake knows what this means and will automatically adjust its rules
+to update and distribute the header file built by `yacc -d'(1). What
+Automake cannot guess, though, is where this header will be used: it is
+up to you to ensure the header gets built before it is first used.
+Typically this is necessary in order for dependency tracking to work
+when the header is included by another file. The common solution is
+listing the header file in `BUILT_SOURCES' (*note Sources::) as follows.
+
+ BUILT_SOURCES = parser.h
+ AM_YFLAGS = -d
+ bin_PROGRAMS = foo
+ foo_SOURCES = ... parser.y ...
+
+ If a `lex' source file is seen, then your `configure.ac' must define
+the variable `LEX'. You can use `AC_PROG_LEX' to do this (*note
+Particular Program Checks: (autoconf)Particular Programs.), but using
+`AM_PROG_LEX' macro (*note Macros::) is recommended.
+
+ When `lex' is invoked, it is passed `AM_LFLAGS' and `LFLAGS'. The
+latter is a user variable and the former is intended for the
+`Makefile.am' author.
+
+ When `AM_MAINTAINER_MODE' (*note maintainer-mode::) is used, the
+rebuild rule for distributed Yacc and Lex sources are only used when
+`maintainer-mode' is enabled, or when the files have been erased.
+
+ When `lex' or `yacc' sources are used, `automake -i' automatically
+installs an auxiliary program called `ylwrap' in your package (*note
+Auxiliary Programs::). This program is used by the build rules to
+rename the output of these tools, and makes it possible to include
+multiple `yacc' (or `lex') source files in a single directory. (This
+is necessary because yacc's output file name is fixed, and a parallel
+make could conceivably invoke more than one instance of `yacc'
+simultaneously.)
+
+ For `yacc', simply managing locking is insufficient. The output of
+`yacc' always uses the same symbol names internally, so it isn't
+possible to link two `yacc' parsers into the same executable.
+
+ We recommend using the following renaming hack used in `gdb':
+ #define yymaxdepth c_maxdepth
+ #define yyparse c_parse
+ #define yylex c_lex
+ #define yyerror c_error
+ #define yylval c_lval
+ #define yychar c_char
+ #define yydebug c_debug
+ #define yypact c_pact
+ #define yyr1 c_r1
+ #define yyr2 c_r2
+ #define yydef c_def
+ #define yychk c_chk
+ #define yypgo c_pgo
+ #define yyact c_act
+ #define yyexca c_exca
+ #define yyerrflag c_errflag
+ #define yynerrs c_nerrs
+ #define yyps c_ps
+ #define yypv c_pv
+ #define yys c_s
+ #define yy_yys c_yys
+ #define yystate c_state
+ #define yytmp c_tmp
+ #define yyv c_v
+ #define yy_yyv c_yyv
+ #define yyval c_val
+ #define yylloc c_lloc
+ #define yyreds c_reds
+ #define yytoks c_toks
+ #define yylhs c_yylhs
+ #define yylen c_yylen
+ #define yydefred c_yydefred
+ #define yydgoto c_yydgoto
+ #define yysindex c_yysindex
+ #define yyrindex c_yyrindex
+ #define yygindex c_yygindex
+ #define yytable c_yytable
+ #define yycheck c_yycheck
+ #define yyname c_yyname
+ #define yyrule c_yyrule
+
+ For each define, replace the `c_' prefix with whatever you like.
+These defines work for `bison', `byacc', and traditional `yacc's. If
+you find a parser generator that uses a symbol not covered here, please
+report the new name so it can be added to the list.
+
+ ---------- Footnotes ----------
+
+ (1) Please note that `automake' recognizes `-d' in `AM_YFLAGS' only
+if it is not clustered with other options; for example, it won't be
+recognized if `AM_YFLAGS' is `-dt', but it will be if `AM_YFLAGS' is
+`-d -t' or `-t -d'.

+
+8.14.3 Mixing Fortran 77 With C and C++
+---------------------------------------
+
+Automake currently provides _limited_ support for creating programs and
+shared libraries that are a mixture of Fortran 77 and C and/or C++.
+However, there are many other issues related to mixing Fortran 77 with
+other languages that are _not_ (currently) handled by Automake, but
+that are handled by other packages(1).
+
+ Automake can help in two ways:
+
+ 1. Automatic selection of the linker depending on which combinations
+ of source code.
+
+ 2. Automatic selection of the appropriate linker flags (e.g., `-L' and
+ `-l') to pass to the automatically selected linker in order to link
+ in the appropriate Fortran 77 intrinsic and run-time libraries.
+
+ These extra Fortran 77 linker flags are supplied in the output
+ variable `FLIBS' by the `AC_F77_LIBRARY_LDFLAGS' Autoconf macro.
+ *Note Fortran Compiler Characteristics: (autoconf)Fortran Compiler.
+
+ If Automake detects that a program or shared library (as mentioned in
+some `_PROGRAMS' or `_LTLIBRARIES' primary) contains source code that
+is a mixture of Fortran 77 and C and/or C++, then it requires that the
+macro `AC_F77_LIBRARY_LDFLAGS' be called in `configure.ac', and that
+either `$(FLIBS)' appear in the appropriate `_LDADD' (for programs) or
+`_LIBADD' (for shared libraries) variables. It is the responsibility
+of the person writing the `Makefile.am' to make sure that `$(FLIBS)'
+appears in the appropriate `_LDADD' or `_LIBADD' variable.
+
+ For example, consider the following `Makefile.am':
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = main.cc foo.f
+ foo_LDADD = libfoo.la $(FLIBS)
+
+ pkglib_LTLIBRARIES = libfoo.la
+ libfoo_la_SOURCES = bar.f baz.c zardoz.cc
+ libfoo_la_LIBADD = $(FLIBS)
+
+ In this case, Automake will insist that `AC_F77_LIBRARY_LDFLAGS' is
+mentioned in `configure.ac'. Also, if `$(FLIBS)' hadn't been mentioned
+in `foo_LDADD' and `libfoo_la_LIBADD', then Automake would have issued
+a warning.

+File: automake.info, Node: How the Linker is Chosen, Up: Mixing Fortran 77 With C and C++
+
+8.14.3.1 How the Linker is Chosen
+.................................
+
+When a program or library mixes several languages, Automake choose the
+linker according to the following priorities. (The names in
+parentheses are the variables containing the link command.)
+
+ 1. Native Java (`GCJLINK')
+
+ 2. Objective C++ (`OBJCXXLINK')
+
+ 3. C++ (`CXXLINK')
+
+ 4. Fortran 77 (`F77LINK')
+
+ 5. Fortran (`FCLINK')
+
+ 6. Objective C (`OBJCLINK')
+
+ 7. Unified Parallel C (`UPCLINK')
+
+ 8. C (`LINK')
+
+ For example, if Fortran 77, C and C++ source code is compiled into a
+program, then the C++ linker will be used. In this case, if the C or
+Fortran 77 linkers required any special libraries that weren't included
+by the C++ linker, then they must be manually added to an `_LDADD' or
+`_LIBADD' variable by the user writing the `Makefile.am'.
+
+ Automake only looks at the file names listed in `_SOURCES' variables
+to choose the linker, and defaults to the C linker. Sometimes this is
+inconvenient because you are linking against a library written in
+another language and would like to set the linker more appropriately.
+*Note Libtool Convenience Libraries::, for a trick with
+`nodist_EXTRA_..._SOURCES'.
+
+ A per-target `_LINK' variable will override the above selection.
+Per-target link flags will cause Automake to write a per-target `_LINK'
+variable according to the language chosen as above.

+ Any package including Fortran 9x code must define the output variable

+
+8.16 Compiling Java sources using gcj
+=====================================
+
+Automake includes support for natively compiled Java, using `gcj', the
+Java front end to the GNU Compiler Collection (rudimentary support for
+compiling Java to bytecode using the `javac' compiler is also present,
+_albeit deprecated_; *note Java::).
+
+ Any package including Java code to be compiled must define the output
+variable `GCJ' in `configure.ac'; the variable `GCJFLAGS' must also be
+defined somehow (either in `configure.ac' or `Makefile.am'). The
+simplest way to do this is to use the `AM_PROG_GCJ' macro.
+
+ By default, programs including Java source files are linked with
+`gcj'.
+
+ As always, the contents of `AM_GCJFLAGS' are passed to every
+compilation invoking `gcj' (in its role as an ahead-of-time compiler,
+when invoking it to create `.class' files, `AM_JAVACFLAGS' is used
+instead). If it is necessary to pass options to `gcj' from
+`Makefile.am', this variable, and not the user variable `GCJFLAGS',
+should be used.
+
+ `gcj' can be used to compile `.java', `.class', `.zip', or `.jar'
+files.
+
+ When linking, `gcj' requires that the main class be specified using
+the `--main=' option. The easiest way to do this is to use the
+`_LDFLAGS' variable for the program.
+
+\1f
+File: automake.info, Node: Vala Support, Next: Support for Other Languages, Prev: Java Support with gcj, Up: Programs
+
+8.17 Vala Support
+=================
+
+Automake provides initial support for Vala
+(`http://www.vala-project.org/'). This requires valac version 0.7.0 or
+later, and currently requires the user to use GNU `make'.
+
+ foo_SOURCES = foo.vala bar.vala zardoc.c
+
+ Any `.vala' file listed in a `_SOURCES' variable will be compiled
+into C code by the Vala compiler. The generated `.c' files are
+distributed. The end user does not need to have a Vala compiler
+installed.
+
+ Automake ships with an Autoconf macro called `AM_PROG_VALAC' that
+will locate the Vala compiler and optionally check its version number.
+
+ -- Macro: AM_PROG_VALAC ([MINIMUM-VERSION])
+ Try to find a Vala compiler in `PATH'. If it is found, the variable
+ `VALAC' is set. Optionally a minimum release number of the compiler
+ can be requested:
+
+ AM_PROG_VALAC([0.7.0])
+
+ There are a few variables that are used when compiling Vala sources:
+
+`VALAC'
+ Path to the Vala compiler.
+
+`VALAFLAGS'
+ Additional arguments for the Vala compiler.
+
+`AM_VALAFLAGS'
+ The maintainer's variant of `VALAFLAGS'.
+
+ lib_LTLIBRARIES = libfoo.la
+ libfoo_la_SOURCES = foo.vala
+
+ Note that currently, you cannot use per-target `*_VALAFLAGS' (*note
+Renamed Objects::) to produce different C files from one Vala source
+file.

+
+8.18 Support for Other Languages
+================================
+
+Automake currently only includes full support for C, C++ (*note C++
+Support::), Objective C (*note Objective C Support::), Objective C++
+(*note Objective C++ Support::), Fortran 77 (*note Fortran 77
+Support::), Fortran 9x (*note Fortran 9x Support::), and Java (*note
+Java Support with gcj::). There is only rudimentary support for other
+languages, support for which will be improved based on user demand.
+
+ Some limited support for adding your own languages is available via
+the suffix rule handling (*note Suffixes::).
+
+\1f
+File: automake.info, Node: Dependencies, Next: EXEEXT, Prev: Support for Other Languages, Up: Programs
+
+8.19 Automatic dependency tracking
+==================================
+
+As a developer it is often painful to continually update the
+`Makefile.am' whenever the include-file dependencies change in a
+project. Automake supplies a way to automatically track dependency
+changes (*note Dependency Tracking::).
+
+ Automake always uses complete dependencies for a compilation,
+including system headers. Automake's model is that dependency
+computation should be a side effect of the build. To this end,
+dependencies are computed by running all compilations through a special
+wrapper program called `depcomp'. `depcomp' understands how to coax
+many different C and C++ compilers into generating dependency
+information in the format it requires. `automake -a' will install
+`depcomp' into your source tree for you. If `depcomp' can't figure out
+how to properly invoke your compiler, dependency tracking will simply
+be disabled for your build.
+
+ Experience with earlier versions of Automake (*note Dependency
+Tracking Evolution: (automake-history)Dependency Tracking Evolution.)
+taught us that it is not reliable to generate dependencies only on the
+maintainer's system, as configurations vary too much. So instead
+Automake implements dependency tracking at build time.
+
+ Automatic dependency tracking can be suppressed by putting
+`no-dependencies' in the variable `AUTOMAKE_OPTIONS', or passing
+`no-dependencies' as an argument to `AM_INIT_AUTOMAKE' (this should be
+the preferred way). Or, you can invoke `automake' with the `-i'
+option. Dependency tracking is enabled by default.
+
+ The person building your package also can choose to disable
+dependency tracking by configuring with `--disable-dependency-tracking'.
+
+\1f
+File: automake.info, Node: EXEEXT, Prev: Dependencies, Up: Programs
+
+8.20 Support for executable extensions
+======================================
+
+On some platforms, such as Windows, executables are expected to have an
+extension such as `.exe'. On these platforms, some compilers (GCC
+among them) will automatically generate `foo.exe' when asked to
+generate `foo'.
+
+ Automake provides mostly-transparent support for this. Unfortunately
+_mostly_ doesn't yet mean _fully_. Until the English dictionary is
+revised, you will have to assist Automake if your package must support
+those platforms.
+
+ One thing you must be aware of is that, internally, Automake rewrites
+something like this:
+
+ bin_PROGRAMS = liver
+
+ to this:
+
+ bin_PROGRAMS = liver$(EXEEXT)
+
+ The targets Automake generates are likewise given the `$(EXEEXT)'
+extension.
+
+ The variables `TESTS' and `XFAIL_TESTS' (*note Simple Tests::) are
+also rewritten if they contain filenames that have been declared as
+programs in the same `Makefile'. (This is mostly useful when some
+programs from `check_PROGRAMS' are listed in `TESTS'.)
+
+ However, Automake cannot apply this rewriting to `configure'
+substitutions. This means that if you are conditionally building a
+program using such a substitution, then your `configure.ac' must take
+care to add `$(EXEEXT)' when constructing the output variable.
+
+ Sometimes maintainers like to write an explicit link rule for their
+program. Without executable extension support, this is easy--you
+simply write a rule whose target is the name of the program. However,
+when executable extension support is enabled, you must instead add the
+`$(EXEEXT)' suffix.
+
+ This might be a nuisance for maintainers who know their package will
+never run on a platform that has executable extensions. For those
+maintainers, the `no-exeext' option (*note Options::) will disable this
+feature. This works in a fairly ugly way; if `no-exeext' is seen, then
+the presence of a rule for a target named `foo' in `Makefile.am' will
+override an `automake'-generated rule for `foo$(EXEEXT)'. Without the
+`no-exeext' option, this use will give a diagnostic.

+supplied, but Automake will still automatically handle installation and
+distribution.

+File: automake.info, Node: Scripts, Next: Headers, Up: Other Objects
+
+9.1 Executable Scripts
+======================
+
+It is possible to define and install programs that are scripts. Such
+programs are listed using the `SCRIPTS' primary name. When the script
+is distributed in its final, installable form, the `Makefile' usually
+looks as follows:
+
+ # Install my_script in $(bindir) and distribute it.
+ dist_bin_SCRIPTS = my_script
+
+ Scripts are not distributed by default; as we have just seen, those
+that should be distributed can be specified using a `dist_' prefix as
+with other primaries.
+
+ Scripts can be installed in `bindir', `sbindir', `libexecdir',
+`pkglibexecdir', or `pkgdatadir'.
+
+ Scripts that need not be installed can be listed in
+`noinst_SCRIPTS', and among them, those which are needed only by `make
+check' should go in `check_SCRIPTS'.
+
+ When a script needs to be built, the `Makefile.am' should include
+the appropriate rules. For instance the `automake' program itself is a
+Perl script that is generated from `automake.in'. Here is how this is
+handled:
+
+ bin_SCRIPTS = automake
+ CLEANFILES = $(bin_SCRIPTS)
+ EXTRA_DIST = automake.in
+
+ do_subst = sed -e 's,[@]datadir[@],$(datadir),g' \
+ -e 's,[@]PERL[@],$(PERL),g' \
+ -e 's,[@]PACKAGE[@],$(PACKAGE),g' \
+ -e 's,[@]VERSION[@],$(VERSION),g' \
+ ...
+
+ automake: automake.in Makefile
+ $(do_subst) < $(srcdir)/automake.in > automake
+ chmod +x automake
+
+ Such scripts for which a build rule has been supplied need to be
+deleted explicitly using `CLEANFILES' (*note Clean::), and their
+sources have to be distributed, usually with `EXTRA_DIST' (*note Basics
+of Distribution::).
+
+ Another common way to build scripts is to process them from
+`configure' with `AC_CONFIG_FILES'. In this situation Automake knows
+which files should be cleaned and distributed, and what the rebuild
+rules should look like.
+
+ For instance if `configure.ac' contains
+
+ AC_CONFIG_FILES([src/my_script], [chmod +x src/my_script])
+
+to build `src/my_script' from `src/my_script.in', then a
+`src/Makefile.am' to install this script in `$(bindir)' can be as
+simple as
+
+ bin_SCRIPTS = my_script
+ CLEANFILES = $(bin_SCRIPTS)
+
+There is no need for `EXTRA_DIST' or any build rule: Automake infers
+them from `AC_CONFIG_FILES' (*note Requirements::). `CLEANFILES' is
+still useful, because by default Automake will clean targets of
+`AC_CONFIG_FILES' in `distclean', not `clean'.
+
+ Although this looks simpler, building scripts this way has one
+drawback: directory variables such as `$(datadir)' are not fully
+expanded and may refer to other directory variables.
+
+\1f
+File: automake.info, Node: Headers, Next: Data, Prev: Scripts, Up: Other Objects
+
+9.2 Header files
+================
+
+Header files that must be installed are specified by the `HEADERS'
+family of variables. Headers can be installed in `includedir',
+`oldincludedir', `pkgincludedir' or any other directory you may have
+defined (*note Uniform::). For instance,
+
+ include_HEADERS = foo.h bar/bar.h
+
+will install the two files as `$(includedir)/foo.h' and
+`$(includedir)/bar.h'.
+
+ The `nobase_' prefix is also supported,
+
+ nobase_include_HEADERS = foo.h bar/bar.h
+
+will install the two files as `$(includedir)/foo.h' and
+`$(includedir)/bar/bar.h' (*note Alternative::).
+
+ Usually, only header files that accompany installed libraries need to
+be installed. Headers used by programs or convenience libraries are
+not installed. The `noinst_HEADERS' variable can be used for such
+headers. However when the header actually belongs to a single
+convenience library or program, we recommend listing it in the
+program's or library's `_SOURCES' variable (*note Program Sources::)
+instead of in `noinst_HEADERS'. This is clearer for the `Makefile.am'
+reader. `noinst_HEADERS' would be the right variable to use in a
+directory containing only headers and no associated library or program.
+
+ All header files must be listed somewhere; in a `_SOURCES' variable
+or in a `_HEADERS' variable. Missing ones will not appear in the
+distribution.
+
+ For header files that are built and must not be distributed, use the
+`nodist_' prefix as in `nodist_include_HEADERS' or
+`nodist_prog_SOURCES'. If these generated headers are needed during
+the build, you must also ensure they exist before they are used (*note
+Sources::).
+
+\1f
+File: automake.info, Node: Data, Next: Sources, Prev: Headers, Up: Other Objects
+
+9.3 Architecture-independent data files
+=======================================
+
+Automake supports the installation of miscellaneous data files using the
+`DATA' family of variables.
+
+ Such data can be installed in the directories `datadir',
+`sysconfdir', `sharedstatedir', `localstatedir', or `pkgdatadir'.
+
+ By default, data files are _not_ included in a distribution. Of
+course, you can use the `dist_' prefix to change this on a per-variable
+basis.
+
+ Here is how Automake declares its auxiliary data files:
+
+ dist_pkgdata_DATA = clean-kr.am clean.am ...
+
+\1f
+File: automake.info, Node: Sources, Prev: Data, Up: Other Objects
+
+9.4 Built Sources
+=================
+
+Because Automake's automatic dependency tracking works as a side-effect
+of compilation (*note Dependencies::) there is a bootstrap issue: a
+target should not be compiled before its dependencies are made, but
+these dependencies are unknown until the target is first compiled.
+
+ Ordinarily this is not a problem, because dependencies are
+distributed sources: they preexist and do not need to be built.
+Suppose that `foo.c' includes `foo.h'. When it first compiles `foo.o',
+`make' only knows that `foo.o' depends on `foo.c'. As a side-effect of
+this compilation `depcomp' records the `foo.h' dependency so that
+following invocations of `make' will honor it. In these conditions,
+it's clear there is no problem: either `foo.o' doesn't exist and has to
+be built (regardless of the dependencies), or accurate dependencies
+exist and they can be used to decide whether `foo.o' should be rebuilt.
+
+ It's a different story if `foo.h' doesn't exist by the first `make'
+run. For instance, there might be a rule to build `foo.h'. This time
+`file.o''s build will fail because the compiler can't find `foo.h'.
+`make' failed to trigger the rule to build `foo.h' first by lack of
+dependency information.
+
+ The `BUILT_SOURCES' variable is a workaround for this problem. A
+source file listed in `BUILT_SOURCES' is made on `make all' or `make
+check' (or even `make install') before other targets are processed.
+However, such a source file is not _compiled_ unless explicitly
+requested by mentioning it in some other `_SOURCES' variable.
+
+ So, to conclude our introductory example, we could use
+`BUILT_SOURCES = foo.h' to ensure `foo.h' gets built before any other
+target (including `foo.o') during `make all' or `make check'.
+
+ `BUILT_SOURCES' is actually a bit of a misnomer, as any file which
+must be created early in the build process can be listed in this
+variable. Moreover, all built sources do not necessarily have to be
+listed in `BUILT_SOURCES'. For instance, a generated `.c' file doesn't
+need to appear in `BUILT_SOURCES' (unless it is included by another
+source), because it's a known dependency of the associated object.
+
+ It might be important to emphasize that `BUILT_SOURCES' is honored
+only by `make all', `make check' and `make install'. This means you
+cannot build a specific target (e.g., `make foo') in a clean tree if it
+depends on a built source. However it will succeed if you have run
+`make all' earlier, because accurate dependencies are already available.
+
+ The next section illustrates and discusses the handling of built
+sources on a toy example.
+
+* Menu:
+
+* Built Sources Example:: Several ways to handle built sources.
+
+\1f
+File: automake.info, Node: Built Sources Example, Up: Sources
+
+9.4.1 Built Sources Example
+---------------------------
+
+Suppose that `foo.c' includes `bindir.h', which is
+installation-dependent and not distributed: it needs to be built. Here
+`bindir.h' defines the preprocessor macro `bindir' to the value of the
+`make' variable `bindir' (inherited from `configure').
+
+ We suggest several implementations below. It's not meant to be an
+exhaustive listing of all ways to handle built sources, but it will give
+you a few ideas if you encounter this issue.
+
+First Try
+.........
+
+This first implementation will illustrate the bootstrap issue mentioned
+in the previous section (*note Sources::).
+
+ Here is a tentative `Makefile.am'.
+
+ # This won't work.
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c
+ nodist_foo_SOURCES = bindir.h
+ CLEANFILES = bindir.h
+ bindir.h: Makefile
+ echo '#define bindir "$(bindir)"' >$@
+
+ This setup doesn't work, because Automake doesn't know that `foo.c'
+includes `bindir.h'. Remember, automatic dependency tracking works as
+a side-effect of compilation, so the dependencies of `foo.o' will be
+known only after `foo.o' has been compiled (*note Dependencies::). The
+symptom is as follows.
+
+ % make
+ source='foo.c' object='foo.o' libtool=no \
+ depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+ depmode=gcc /bin/sh ./depcomp \
+ gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+ foo.c:2: bindir.h: No such file or directory
+ make: *** [foo.o] Error 1
+
+ In this example `bindir.h' is not distributed nor installed, and it
+is not even being built on-time. One may wonder if the
+`nodist_foo_SOURCES = bindir.h' line has any use at all. This line
+simply states that `bindir.h' is a source of `foo', so for instance, it
+should be inspected while generating tags (*note Tags::). In other
+words, it does not help our present problem, and the build would fail
+identically without it.
+
+Using `BUILT_SOURCES'
+.....................
+
+A solution is to require `bindir.h' to be built before anything else.
+This is what `BUILT_SOURCES' is meant for (*note Sources::).
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c
+ nodist_foo_SOURCES = bindir.h
+ BUILT_SOURCES = bindir.h
+ CLEANFILES = bindir.h
+ bindir.h: Makefile
+ echo '#define bindir "$(bindir)"' >$@
+
+ See how `bindir.h' gets built first:
+
+ % make
+ echo '#define bindir "/usr/local/bin"' >bindir.h
+ make all-am
+ make[1]: Entering directory `/home/adl/tmp'
+ source='foo.c' object='foo.o' libtool=no \
+ depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+ depmode=gcc /bin/sh ./depcomp \
+ gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+ gcc -g -O2 -o foo foo.o
+ make[1]: Leaving directory `/home/adl/tmp'
+
+ However, as said earlier, `BUILT_SOURCES' applies only to the `all',
+`check', and `install' targets. It still fails if you try to run `make
+foo' explicitly:
+
+ % make clean
+ test -z "bindir.h" || rm -f bindir.h
+ test -z "foo" || rm -f foo
+ rm -f *.o
+ % : > .deps/foo.Po # Suppress previously recorded dependencies
+ % make foo
+ source='foo.c' object='foo.o' libtool=no \
+ depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+ depmode=gcc /bin/sh ./depcomp \
+ gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+ foo.c:2: bindir.h: No such file or directory
+ make: *** [foo.o] Error 1
+
+Recording Dependencies manually
+...............................
+
+Usually people are happy enough with `BUILT_SOURCES' because they never
+build targets such as `make foo' before `make all', as in the previous
+example. However if this matters to you, you can avoid `BUILT_SOURCES'
+and record such dependencies explicitly in the `Makefile.am'.
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c
+ nodist_foo_SOURCES = bindir.h
+ foo.$(OBJEXT): bindir.h
+ CLEANFILES = bindir.h
+ bindir.h: Makefile
+ echo '#define bindir "$(bindir)"' >$@
+
+ You don't have to list _all_ the dependencies of `foo.o' explicitly,
+only those that might need to be built. If a dependency already
+exists, it will not hinder the first compilation and will be recorded
+by the normal dependency tracking code. (Note that after this first
+compilation the dependency tracking code will also have recorded the
+dependency between `foo.o' and `bindir.h'; so our explicit dependency
+is really useful to the first build only.)
+
+ Adding explicit dependencies like this can be a bit dangerous if you
+are not careful enough. This is due to the way Automake tries not to
+overwrite your rules (it assumes you know better than it).
+`foo.$(OBJEXT): bindir.h' supersedes any rule Automake may want to
+output to build `foo.$(OBJEXT)'. It happens to work in this case
+because Automake doesn't have to output any `foo.$(OBJEXT):' target: it
+relies on a suffix rule instead (i.e., `.c.$(OBJEXT):'). Always check
+the generated `Makefile.in' if you do this.
+
+Build `bindir.h' from `configure'
+.................................
+
+It's possible to define this preprocessor macro from `configure',
+either in `config.h' (*note Defining Directories: (autoconf)Defining
+Directories.), or by processing a `bindir.h.in' file using
+`AC_CONFIG_FILES' (*note Configuration Actions: (autoconf)Configuration
+Actions.).
+
+ At this point it should be clear that building `bindir.h' from
+`configure' works well for this example. `bindir.h' will exist before
+you build any target, hence will not cause any dependency issue.
+
+ The Makefile can be shrunk as follows. We do not even have to
+mention `bindir.h'.
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c
+
+ However, it's not always possible to build sources from `configure',
+especially when these sources are generated by a tool that needs to be
+built first.
+
+Build `bindir.c', not `bindir.h'.
+.................................
+
+Another attractive idea is to define `bindir' as a variable or function
+exported from `bindir.o', and build `bindir.c' instead of `bindir.h'.
+
+ noinst_PROGRAMS = foo
+ foo_SOURCES = foo.c bindir.h
+ nodist_foo_SOURCES = bindir.c
+ CLEANFILES = bindir.c
+ bindir.c: Makefile
+ echo 'const char bindir[] = "$(bindir)";' >$@
+
+ `bindir.h' contains just the variable's declaration and doesn't need
+to be built, so it won't cause any trouble. `bindir.o' is always
+dependent on `bindir.c', so `bindir.c' will get built first.
+
+Which is best?
+..............
+
+There is no panacea, of course. Each solution has its merits and
+drawbacks.
+
+ You cannot use `BUILT_SOURCES' if the ability to run `make foo' on a
+clean tree is important to you.
+
+ You won't add explicit dependencies if you are leery of overriding
+an Automake rule by mistake.
+
+ Building files from `./configure' is not always possible, neither is
+converting `.h' files into `.c' files.

+10 Other GNU Tools
+******************
+
+Since Automake is primarily intended to generate `Makefile.in's for use
+in GNU programs, it tries hard to interoperate with other GNU tools.

+
+\1f
+File: automake.info, Node: Emacs Lisp, Next: gettext, Up: Other GNU Tools
+
+10.1 Emacs Lisp
+===============
+
+Automake provides some support for Emacs Lisp. The `LISP' primary is
+used to hold a list of `.el' files. Possible prefixes for this primary
+are `lisp_' and `noinst_'. Note that if `lisp_LISP' is defined, then
+`configure.ac' must run `AM_PATH_LISPDIR' (*note Macros::).
+
+ Lisp sources are not distributed by default. You can prefix the
+`LISP' primary with `dist_', as in `dist_lisp_LISP' or
+`dist_noinst_LISP', to indicate that these files should be distributed.
+
+ Automake will byte-compile all Emacs Lisp source files using the
+Emacs found by `AM_PATH_LISPDIR', if any was found.
+
+ Byte-compiled Emacs Lisp files are not portable among all versions of
+Emacs, so it makes sense to turn this off if you expect sites to have
+more than one version of Emacs installed. Furthermore, many packages
+don't actually benefit from byte-compilation. Still, we recommend that
+you byte-compile your Emacs Lisp sources. It is probably better for
+sites with strange setups to cope for themselves than to make the
+installation less nice for everybody else.
+
+ There are two ways to avoid byte-compiling. Historically, we have
+recommended the following construct.
+
+ lisp_LISP = file1.el file2.el
+ ELCFILES =
+
+`ELCFILES' is an internal Automake variable that normally lists all
+`.elc' files that must be byte-compiled. Automake defines `ELCFILES'
+automatically from `lisp_LISP'. Emptying this variable explicitly
+prevents byte-compilation.
+
+ Since Automake 1.8, we now recommend using `lisp_DATA' instead:
+
+ lisp_DATA = file1.el file2.el
+
+ Note that these two constructs are not equivalent. `_LISP' will not
+install a file if Emacs is not installed, while `_DATA' will always
+install its files.
+

+
+10.2 Gettext
+============
+
+If `AM_GNU_GETTEXT' is seen in `configure.ac', then Automake turns on
+support for GNU gettext, a message catalog system for
+internationalization (*note Introduction: (gettext)Top.).
+
+ The `gettext' support in Automake requires the addition of one or
+two subdirectories to the package: `po' and possibly also `intl'. The
+latter is needed if `AM_GNU_GETTEXT' is not invoked with the `external'
+argument, or if `AM_GNU_GETTEXT_INTL_SUBDIR' is used. Automake ensures
+that these directories exist and are mentioned in `SUBDIRS'.
+
+\1f
+File: automake.info, Node: Libtool, Next: Java, Prev: gettext, Up: Other GNU Tools
+
+10.3 Libtool
+============
+
+Automake provides support for GNU Libtool (*note Introduction:
+(libtool)Top.) with the `LTLIBRARIES' primary. *Note A Shared
+Library::.
+
+\1f
+File: automake.info, Node: Java, Next: Python, Prev: Libtool, Up: Other GNU Tools
+
+10.4 Java bytecode compilation (deprecated)
+===========================================
+
+Automake provides some minimal support for Java bytecode compilation
+with the `JAVA' primary (in addition to the support for compiling Java
+to native machine code; *note Java Support with gcj::). Note however
+that _the interface and most features described here are deprecated_;
+the next automake release will strive to provide a better and cleaner
+interface, which however _won't be backward-compatible_; the present
+interface will probably be removed altogether in future automake
+releases (1.13 or later), so don't use it in new code.
+
+ Any `.java' files listed in a `_JAVA' variable will be compiled with
+`JAVAC' at build time. By default, `.java' files are not included in
+the distribution, you should use the `dist_' prefix to distribute them.
+
+ Here is a typical setup for distributing `.java' files and
+installing the `.class' files resulting from their compilation.
+
+ javadir = $(datadir)/java
+ dist_java_JAVA = a.java b.java ...
+
+ Currently Automake enforces the restriction that only one `_JAVA'
+primary can be used in a given `Makefile.am'. The reason for this
+restriction is that, in general, it isn't possible to know which
+`.class' files were generated from which `.java' files, so it would be
+impossible to know which files to install where. For instance, a
+`.java' file can define multiple classes; the resulting `.class' file
+names cannot be predicted without parsing the `.java' file.
+
+ There are a few variables that are used when compiling Java sources:
+
+`JAVAC'
+ The name of the Java compiler. This defaults to `javac'.
+
+`JAVACFLAGS'
+ The flags to pass to the compiler. This is considered to be a user
+ variable (*note User Variables::).
+
+`AM_JAVACFLAGS'
+ More flags to pass to the Java compiler. This, and not
+ `JAVACFLAGS', should be used when it is necessary to put Java
+ compiler flags into `Makefile.am'.
+
+`JAVAROOT'
+ The value of this variable is passed to the `-d' option to
+ `javac'. It defaults to `$(top_builddir)'.
+
+`CLASSPATH_ENV'
+ This variable is a shell expression that is used to set the
+ `CLASSPATH' environment variable on the `javac' command line. (In
+ the future we will probably handle class path setting differently.)
+
+\1f
+File: automake.info, Node: Python, Prev: Java, Up: Other GNU Tools
+
+10.5 Python
+===========
+
+Automake provides support for Python compilation with the `PYTHON'
+primary. A typical setup is to call `AM_PATH_PYTHON' in `configure.ac'
+and use a line like the following in `Makefile.am':
+
+ python_PYTHON = tree.py leave.py
+
+ Any files listed in a `_PYTHON' variable will be byte-compiled with
+`py-compile' at install time. `py-compile' actually creates both
+standard (`.pyc') and optimized (`.pyo') byte-compiled versions of the
+source files. Note that because byte-compilation occurs at install
+time, any files listed in `noinst_PYTHON' will not be compiled. Python
+source files are included in the distribution by default, prepend
+`nodist_' (as in `nodist_python_PYTHON') to omit them.
+
+ Automake ships with an Autoconf macro called `AM_PATH_PYTHON' that
+will determine some Python-related directory variables (see below). If
+you have called `AM_PATH_PYTHON' from `configure.ac', then you may use
+the variables `python_PYTHON' or `pkgpython_PYTHON' to list Python
+source files in your `Makefile.am', depending on where you want your
+files installed (see the definitions of `pythondir' and `pkgpythondir'
+below).
+
+ -- Macro: AM_PATH_PYTHON ([VERSION], [ACTION-IF-FOUND],
+ [ACTION-IF-NOT-FOUND])
+
+ Search for a Python interpreter on the system. This macro takes
+ three optional arguments. The first argument, if present, is the
+ minimum version of Python required for this package:
+ `AM_PATH_PYTHON' will skip any Python interpreter that is older
+ than VERSION. If an interpreter is found and satisfies VERSION,
+ then ACTION-IF-FOUND is run. Otherwise, ACTION-IF-NOT-FOUND is
+ run.
+
+ If ACTION-IF-NOT-FOUND is not specified, as in the following
+ example, the default is to abort `configure'.
+
+ AM_PATH_PYTHON([2.2])
+
+ This is fine when Python is an absolute requirement for the
+ package. If Python >= 2.5 was only _optional_ to the package,
+ `AM_PATH_PYTHON' could be called as follows.
+
+ AM_PATH_PYTHON([2.5],, [:])
+
+ If the `PYTHON' variable is set when `AM_PATH_PYTHON' is called,
+ then that will be the only Python interpreter that is tried.
+
+ `AM_PATH_PYTHON' creates the following output variables based on
+ the Python installation found during configuration.
+
+`PYTHON'
+ The name of the Python executable, or `:' if no suitable
+ interpreter could be found.
+
+ Assuming ACTION-IF-NOT-FOUND is used (otherwise `./configure' will
+ abort if Python is absent), the value of `PYTHON' can be used to
+ setup a conditional in order to disable the relevant part of a
+ build as follows.
+
+ AM_PATH_PYTHON(,, [:])
+ AM_CONDITIONAL([HAVE_PYTHON], [test "$PYTHON" != :])
+
+`PYTHON_VERSION'
+ The Python version number, in the form MAJOR.MINOR (e.g., `2.5').
+ This is currently the value of `sys.version[:3]'.
+
+`PYTHON_PREFIX'
+ The string `${prefix}'. This term may be used in future work that
+ needs the contents of Python's `sys.prefix', but general consensus
+ is to always use the value from `configure'.
+
+`PYTHON_EXEC_PREFIX'
+ The string `${exec_prefix}'. This term may be used in future work
+ that needs the contents of Python's `sys.exec_prefix', but general
+ consensus is to always use the value from `configure'.
+
+`PYTHON_PLATFORM'
+ The canonical name used by Python to describe the operating
+ system, as given by `sys.platform'. This value is sometimes
+ needed when building Python extensions.
+
+`pythondir'
+ The directory name for the `site-packages' subdirectory of the
+ standard Python install tree.
+
+`pkgpythondir'
+ This is the directory under `pythondir' that is named after the
+ package. That is, it is `$(pythondir)/$(PACKAGE)'. It is provided
+ as a convenience.
+
+`pyexecdir'
+ This is the directory where Python extension modules (shared
+ libraries) should be installed. An extension module written in C
+ could be declared as follows to Automake:
+
+ pyexec_LTLIBRARIES = quaternion.la
+ quaternion_la_SOURCES = quaternion.c support.c support.h
+ quaternion_la_LDFLAGS = -avoid-version -module
+
+`pkgpyexecdir'
+ This is a convenience variable that is defined as
+ `$(pyexecdir)/$(PACKAGE)'.
+
+ All these directory variables have values that start with either
+`${prefix}' or `${exec_prefix}' unexpanded. This works fine in
+`Makefiles', but it makes these variables hard to use in `configure'.
+This is mandated by the GNU coding standards, so that the user can run
+`make prefix=/foo install'. The Autoconf manual has a section with
+more details on this topic (*note Installation Directory Variables:
+(autoconf)Installation Directory Variables.). See also *note
+Hard-Coded Install Paths::.

+11 Building documentation
+*************************
+
+Currently Automake provides support for Texinfo and man pages.
+
+* Menu:
+
+* Texinfo:: Texinfo
+* Man Pages:: Man pages
+
+\1f
+File: automake.info, Node: Texinfo, Next: Man Pages, Up: Documentation
+
+11.1 Texinfo
+============
+
+If the current directory contains Texinfo source, you must declare it
+with the `TEXINFOS' primary. Generally Texinfo files are converted
+into info, and thus the `info_TEXINFOS' variable is most commonly used
+here. Any Texinfo source file must end in the `.texi', `.txi', or
+`.texinfo' extension. We recommend `.texi' for new manuals.
+
+ Automake generates rules to build `.info', `.dvi', `.ps', `.pdf' and
+`.html' files from your Texinfo sources. Following the GNU Coding
+Standards, only the `.info' files are built by `make all' and installed
+by `make install' (unless you use `no-installinfo', see below).
+Furthermore, `.info' files are automatically distributed so that
+Texinfo is not a prerequisite for installing your package.
+
+ Other documentation formats can be built on request by `make dvi',
+`make ps', `make pdf' and `make html', and they can be installed with
+`make install-dvi', `make install-ps', `make install-pdf' and `make
+install-html' explicitly. `make uninstall' will remove everything: the
+Texinfo documentation installed by default as well as all the above
+optional formats.
+
+ All these targets can be extended using `-local' rules (*note
+Extending::).
+
+ If the `.texi' file `@include's `version.texi', then that file will
+be automatically generated. The file `version.texi' defines four
+Texinfo flag you can reference using `@value{EDITION}',
+`@value{VERSION}', `@value{UPDATED}', and `@value{UPDATED-MONTH}'.
+
+`EDITION'
+`VERSION'
+ Both of these flags hold the version number of your program. They
+ are kept separate for clarity.
+
+`UPDATED'
+ This holds the date the primary `.texi' file was last modified.
+
+`UPDATED-MONTH'
+ This holds the name of the month in which the primary `.texi' file
+ was last modified.
+
+ The `version.texi' support requires the `mdate-sh' script; this
+script is supplied with Automake and automatically included when
+`automake' is invoked with the `--add-missing' option.
+
+ If you have multiple Texinfo files, and you want to use the
+`version.texi' feature, then you have to have a separate version file
+for each Texinfo file. Automake will treat any include in a Texinfo
+file that matches `vers*.texi' just as an automatically generated
+version file.
+
+ Sometimes an info file actually depends on more than one `.texi'
+file. For instance, in GNU Hello, `hello.texi' includes the file
+`fdl.texi'. You can tell Automake about these dependencies using the
+`TEXI_TEXINFOS' variable. Here is how GNU Hello does it:
+
+ info_TEXINFOS = hello.texi
+ hello_TEXINFOS = fdl.texi
+
+ By default, Automake requires the file `texinfo.tex' to appear in
+the same directory as the `Makefile.am' file that lists the `.texi'
+files. If you used `AC_CONFIG_AUX_DIR' in `configure.ac' (*note
+Finding `configure' Input: (autoconf)Input.), then `texinfo.tex' is
+looked for there. In both cases, `automake' then supplies
+`texinfo.tex' if `--add-missing' is given, and takes care of its
+distribution. However, if you set the `TEXINFO_TEX' variable (see
+below), it overrides the location of the file and turns off its
+installation into the source as well as its distribution.
+
+ The option `no-texinfo.tex' can be used to eliminate the requirement
+for the file `texinfo.tex'. Use of the variable `TEXINFO_TEX' is
+preferable, however, because that allows the `dvi', `ps', and `pdf'
+targets to still work.
+
+ Automake generates an `install-info' rule; some people apparently
+use this. By default, info pages are installed by `make install', so
+running `make install-info' is pointless. This can be prevented via
+the `no-installinfo' option. In this case, `.info' files are not
+installed by default, and user must request this explicitly using `make
+install-info'.
+
+ By default, `make install-info' and `make install-info' will try to
+run the `install-info' program (if available) to update (or create) the
+``${infodir}'/dir' index. If this is undesired, it can be prevented by
+exporting the `AM_UPDATE_INFO_DIR' variable to "`no'".
+
+ The following variables are used by the Texinfo build rules.
+
+`MAKEINFO'
+ The name of the program invoked to build `.info' files. This
+ variable is defined by Automake. If the `makeinfo' program is
+ found on the system then it will be used by default; otherwise
+ `missing' will be used instead.
+
+`MAKEINFOHTML'
+ The command invoked to build `.html' files. Automake defines this
+ to `$(MAKEINFO) --html'.
+
+`MAKEINFOFLAGS'
+ User flags passed to each invocation of `$(MAKEINFO)' and
+ `$(MAKEINFOHTML)'. This user variable (*note User Variables::) is
+ not expected to be defined in any `Makefile'; it can be used by
+ users to pass extra flags to suit their needs.
+
+`AM_MAKEINFOFLAGS'
+`AM_MAKEINFOHTMLFLAGS'
+ Maintainer flags passed to each `makeinfo' invocation. Unlike
+ `MAKEINFOFLAGS', these variables are meant to be defined by
+ maintainers in `Makefile.am'. `$(AM_MAKEINFOFLAGS)' is passed to
+ `makeinfo' when building `.info' files; and
+ `$(AM_MAKEINFOHTMLFLAGS)' is used when building `.html' files.
+
+ For instance, the following setting can be used to obtain one
+ single `.html' file per manual, without node separators.
+ AM_MAKEINFOHTMLFLAGS = --no-headers --no-split
+
+ `AM_MAKEINFOHTMLFLAGS' defaults to `$(AM_MAKEINFOFLAGS)'. This
+ means that defining `AM_MAKEINFOFLAGS' without defining
+ `AM_MAKEINFOHTMLFLAGS' will impact builds of both `.info' and
+ `.html' files.
+
+`TEXI2DVI'
+ The name of the command that converts a `.texi' file into a `.dvi'
+ file. This defaults to `texi2dvi', a script that ships with the
+ Texinfo package.
+
+`TEXI2PDF'
+ The name of the command that translates a `.texi' file into a
+ `.pdf' file. This defaults to `$(TEXI2DVI) --pdf --batch'.
+
+`DVIPS'
+ The name of the command that builds a `.ps' file out of a `.dvi'
+ file. This defaults to `dvips'.
+
+`TEXINFO_TEX'
+ If your package has Texinfo files in many directories, you can use
+ the variable `TEXINFO_TEX' to tell Automake where to find the
+ canonical `texinfo.tex' for your package. The value of this
+ variable should be the relative path from the current
+ `Makefile.am' to `texinfo.tex':
+
+ TEXINFO_TEX = ../doc/texinfo.tex
+
+\1f
+File: automake.info, Node: Man Pages, Prev: Texinfo, Up: Documentation
+
+11.2 Man Pages
+==============
+
+A package can also include man pages (but see the GNU standards on this
+matter, *note Man Pages: (standards)Man Pages.) Man pages are declared
+using the `MANS' primary. Generally the `man_MANS' variable is used.
+Man pages are automatically installed in the correct subdirectory of
+`mandir', based on the file extension.
+
+ File extensions such as `.1c' are handled by looking for the valid
+part of the extension and using that to determine the correct
+subdirectory of `mandir'. Valid section names are the digits `0'
+through `9', and the letters `l' and `n'.
+
+ Sometimes developers prefer to name a man page something like
+`foo.man' in the source, and then rename it to have the correct suffix,
+for example `foo.1', when installing the file. Automake also supports
+this mode. For a valid section named SECTION, there is a corresponding
+directory named `manSECTIONdir', and a corresponding `_MANS' variable.
+Files listed in such a variable are installed in the indicated section.
+If the file already has a valid suffix, then it is installed as-is;
+otherwise the file suffix is changed to match the section.
+
+ For instance, consider this example:
+ man1_MANS = rename.man thesame.1 alsothesame.1c
+
+In this case, `rename.man' will be renamed to `rename.1' when
+installed, but the other files will keep their names.
+
+ By default, man pages are installed by `make install'. However,
+since the GNU project does not require man pages, many maintainers do
+not expend effort to keep the man pages up to date. In these cases, the
+`no-installman' option will prevent the man pages from being installed
+by default. The user can still explicitly install them via `make
+install-man'.
+
+ For fast installation, with many files it is preferable to use
+`manSECTION_MANS' over `man_MANS' as well as files that do not need to
+be renamed.
+
+ Man pages are not currently considered to be source, because it is
+not uncommon for man pages to be automatically generated. Therefore
+they are not automatically included in the distribution. However, this
+can be changed by use of the `dist_' prefix. For instance here is how
+to distribute and install the two man pages of GNU `cpio' (which
+includes both Texinfo documentation and man pages):
+
+ dist_man_MANS = cpio.1 mt.1
+
+ The `nobase_' prefix is meaningless for man pages and is disallowed.
+
+ Executables and manpages may be renamed upon installation (*note
+Renaming::). For manpages this can be avoided by use of the `notrans_'
+prefix. For instance, suppose an executable `foo' allowing to access a
+library function `foo' from the command line. The way to avoid
+renaming of the `foo.3' manpage is:
+
+ man_MANS = foo.1
+ notrans_man_MANS = foo.3
+
+ `notrans_' must be specified first when used in conjunction with
+either `dist_' or `nodist_' (*note Fine-grained Distribution
+Control::). For instance:
+
+ notrans_dist_man3_MANS = bar.3

+12.1 Basics of Installation
+===========================
+
+A file named in a primary is installed by copying the built file into
+the appropriate directory. The base name of the file is used when
+installing.
+
+ bin_PROGRAMS = hello subdir/goodbye
+
+ In this example, both `hello' and `goodbye' will be installed in
+`$(bindir)'.
+
+ Sometimes it is useful to avoid the basename step at install time.
+For instance, you might have a number of header files in subdirectories
+of the source tree that are laid out precisely how you want to install
+them. In this situation you can use the `nobase_' prefix to suppress
+the base name step. For example:
+
+ nobase_include_HEADERS = stdio.h sys/types.h
+
+will install `stdio.h' in `$(includedir)' and `types.h' in
+`$(includedir)/sys'.
+
+ For most file types, Automake will install multiple files at once,
+while avoiding command line length issues (*note Length Limitations::).
+Since some `install' programs will not install the same file twice in
+one invocation, you may need to ensure that file lists are unique within
+one variable such as `nobase_include_HEADERS' above.
+
+ You should not rely on the order in which files listed in one
+variable are installed. Likewise, to cater for parallel make, you
+should not rely on any particular file installation order even among
+different file types (library dependencies are an exception here).

+File: automake.info, Node: The Two Parts of Install, Next: Extending Installation, Prev: Basics of Installation, Up: Install
+
+12.2 The Two Parts of Install
+=============================
+
+Automake generates separate `install-data' and `install-exec' rules, in
+case the installer is installing on multiple machines that share
+directory structure--these targets allow the machine-independent parts
+to be installed only once. `install-exec' installs platform-dependent
+files, and `install-data' installs platform-independent files. The
+`install' target depends on both of these targets. While Automake
+tries to automatically segregate objects into the correct category, the
+`Makefile.am' author is, in the end, responsible for making sure this
+is done correctly.
+
+ Variables using the standard directory prefixes `data', `info',
+`man', `include', `oldinclude', `pkgdata', or `pkginclude' are
+installed by `install-data'.
+
+ Variables using the standard directory prefixes `bin', `sbin',
+`libexec', `sysconf', `localstate', `lib', or `pkglib' are installed by
+`install-exec'.
+
+ For instance, `data_DATA' files are installed by `install-data',
+while `bin_PROGRAMS' files are installed by `install-exec'.
+
+ Any variable using a user-defined directory prefix with `exec' in
+the name (e.g., `myexecbin_PROGRAMS') is installed by `install-exec'.
+All other user-defined prefixes are installed by `install-data'.
+
+\1f
+File: automake.info, Node: Extending Installation, Next: Staged Installs, Prev: The Two Parts of Install, Up: Install
+
+12.3 Extending Installation
+===========================
+
+It is possible to extend this mechanism by defining an
+`install-exec-local' or `install-data-local' rule. If these rules
+exist, they will be run at `make install' time. These rules can do
+almost anything; care is required.
+
+ Automake also supports two install hooks, `install-exec-hook' and
+`install-data-hook'. These hooks are run after all other install rules
+of the appropriate type, exec or data, have completed. So, for
+instance, it is possible to perform post-installation modifications
+using an install hook. *Note Extending::, for some examples.
+
+\1f
+File: automake.info, Node: Staged Installs, Next: Install Rules for the User, Prev: Extending Installation, Up: Install
+
+12.4 Staged Installs
+====================
+
+Automake generates support for the `DESTDIR' variable in all install
+rules. `DESTDIR' is used during the `make install' step to relocate
+install objects into a staging area. Each object and path is prefixed
+with the value of `DESTDIR' before being copied into the install area.
+Here is an example of typical DESTDIR usage:
+
+ mkdir /tmp/staging &&
+ make DESTDIR=/tmp/staging install
+
+ The `mkdir' command avoids a security problem if the attacker
+creates a symbolic link from `/tmp/staging' to a victim area; then
+`make' places install objects in a directory tree built under
+`/tmp/staging'. If `/gnu/bin/foo' and `/gnu/share/aclocal/foo.m4' are
+to be installed, the above command would install
+`/tmp/staging/gnu/bin/foo' and `/tmp/staging/gnu/share/aclocal/foo.m4'.
+
+ This feature is commonly used to build install images and packages
+(*note DESTDIR::).
+
+ Support for `DESTDIR' is implemented by coding it directly into the
+install rules. If your `Makefile.am' uses a local install rule (e.g.,
+`install-exec-local') or an install hook, then you must write that code
+to respect `DESTDIR'.
+
+ *Note Makefile Conventions: (standards)Makefile Conventions, for
+another usage example.

+
+12.5 Install Rules for the User
+===============================
+
+Automake also generates rules for targets `uninstall', `installdirs',
+and `install-strip'.
+
+ Automake supports `uninstall-local' and `uninstall-hook'. There is
+no notion of separate uninstalls for "exec" and "data", as these
+features would not provide additional functionality.
+
+ Note that `uninstall' is not meant as a replacement for a real
+packaging tool.

+
+13 What Gets Cleaned
+********************
+
+The GNU Makefile Standards specify a number of different clean rules.
+*Note Standard Targets for Users: (standards)Standard Targets.
+
+ Generally the files that can be cleaned are determined automatically
+by Automake. Of course, Automake also recognizes some variables that
+can be defined to specify additional files to clean. These variables
+are `MOSTLYCLEANFILES', `CLEANFILES', `DISTCLEANFILES', and
+`MAINTAINERCLEANFILES'.
+
+ When cleaning involves more than deleting some hard-coded list of
+files, it is also possible to supplement the cleaning rules with your
+own commands. Simply define a rule for any of the `mostlyclean-local',
+`clean-local', `distclean-local', or `maintainer-clean-local' targets
+(*note Extending::). A common case is deleting a directory, for
+instance, a directory created by the test suite:
+
+ clean-local:
+ -rm -rf testSubDir
+
+ Since `make' allows only one set of rules for a given target, a more
+extensible way of writing this is to use a separate target listed as a
+dependency:
+
+ clean-local: clean-local-check
+ .PHONY: clean-local-check
+ clean-local-check:
+ -rm -rf testSubDir
+
+ As the GNU Standards aren't always explicit as to which files should
+be removed by which rule, we've adopted a heuristic that we believe was
+first formulated by Franc,ois Pinard:
+
+ * If `make' built it, and it is commonly something that one would
+ want to rebuild (for instance, a `.o' file), then `mostlyclean'
+ should delete it.
+
+ * Otherwise, if `make' built it, then `clean' should delete it.
+
+ * If `configure' built it, then `distclean' should delete it.
+
+ * If the maintainer built it (for instance, a `.info' file), then
+ `maintainer-clean' should delete it. However `maintainer-clean'
+ should not delete anything that needs to exist in order to run
+ `./configure && make'.
+
+ We recommend that you follow this same set of heuristics in your
+`Makefile.am'.

+
+\1f
+File: automake.info, Node: Basics of Distribution, Next: Fine-grained Distribution Control, Up: Dist
+
+14.1 Basics of Distribution
+===========================
+
+The `dist' rule in the generated `Makefile.in' can be used to generate
+a gzipped `tar' file and other flavors of archive for distribution.
+The file is named based on the `PACKAGE' and `VERSION' variables
+defined by `AM_INIT_AUTOMAKE' (*note Macros::); more precisely the
+gzipped `tar' file is named `PACKAGE-VERSION.tar.gz'. You can use the
+`make' variable `GZIP_ENV' to control how gzip is run. The default
+setting is `--best'.
+
+ For the most part, the files to distribute are automatically found by
+Automake: all source files are automatically included in a distribution,
+as are all `Makefile.am' and `Makefile.in' files. Automake also has a
+built-in list of commonly used files that are automatically included if
+they are found in the current directory (either physically, or as the
+target of a `Makefile.am' rule); this list is printed by `automake
+--help'. Note that some files in this list are actually distributed
+only if other certain conditions hold (for example, the `config.h.top'
+and `config.h.bot' files are automatically distributed only if, e.g.,
+`AC_CONFIG_HEADERS([config.h])' is used in `configure.ac'). Also,
+files that are read by `configure' (i.e. the source files corresponding
+to the files specified in various Autoconf macros such as
+`AC_CONFIG_FILES' and siblings) are automatically distributed. Files
+included in a `Makefile.am' (using `include') or in `configure.ac'
+(using `m4_include'), and helper scripts installed with `automake
+--add-missing' are also distributed.
+
+ Still, sometimes there are files that must be distributed, but which
+are not covered in the automatic rules. These files should be listed in
+the `EXTRA_DIST' variable. You can mention files from subdirectories
+in `EXTRA_DIST'.
+
+ You can also mention a directory in `EXTRA_DIST'; in this case the
+entire directory will be recursively copied into the distribution.
+Please note that this will also copy _everything_ in the directory,
+including, e.g., Subversion's `.svn' private directories or CVS/RCS
+version control files. We recommend against using this feature.
+
+ If you define `SUBDIRS', Automake will recursively include the
+subdirectories in the distribution. If `SUBDIRS' is defined
+conditionally (*note Conditionals::), Automake will normally include
+all directories that could possibly appear in `SUBDIRS' in the
+distribution. If you need to specify the set of directories
+conditionally, you can set the variable `DIST_SUBDIRS' to the exact
+list of subdirectories to include in the distribution (*note
+Conditional Subdirectories::).
+
+\1f
+File: automake.info, Node: Fine-grained Distribution Control, Next: The dist Hook, Prev: Basics of Distribution, Up: Dist
+
+14.2 Fine-grained Distribution Control
+======================================
+
+Sometimes you need tighter control over what does _not_ go into the
+distribution; for instance, you might have source files that are
+generated and that you do not want to distribute. In this case
+Automake gives fine-grained control using the `dist' and `nodist'
+prefixes. Any primary or `_SOURCES' variable can be prefixed with
+`dist_' to add the listed files to the distribution. Similarly,
+`nodist_' can be used to omit the files from the distribution.
+
+ As an example, here is how you would cause some data to be
+distributed while leaving some source code out of the distribution:
+
+ dist_data_DATA = distribute-this
+ bin_PROGRAMS = foo
+ nodist_foo_SOURCES = do-not-distribute.c
+
+\1f
+File: automake.info, Node: The dist Hook, Next: Checking the Distribution, Prev: Fine-grained Distribution Control, Up: Dist
+
+14.3 The dist Hook
+==================
+
+Occasionally it is useful to be able to change the distribution before
+it is packaged up. If the `dist-hook' rule exists, it is run after the
+distribution directory is filled, but before the actual distribution
+archives are created. One way to use this is for removing unnecessary
+files that get recursively included by specifying a directory in
+`EXTRA_DIST':
+
+ EXTRA_DIST = doc
+ dist-hook:
+ rm -rf `find $(distdir)/doc -type d -name .svn`
+
+Note that the `dist-hook' recipe shouldn't assume that the regular
+files in the distribution directory are writable; this might not be the
+case if one is packaging from a read-only source tree, or when a `make
+distcheck' is being done. For similar reasons, the recipe shouldn't
+assume that the subdirectories put into the distribution directory as
+effect of having them listed in `EXTRA_DIST' are writable. So, if the
+`dist-hook' recipe wants to modify the content of an existing file (or
+`EXTRA_DIST' subdirectory) in the distribution directory, it should
+explicitly to make it writable first:
+
+ EXTRA_DIST = README doc
+ dist-hook:
+ chmod u+w $(distdir)/README $(distdir)/doc
+ echo "Distribution date: `date`" >> README
+ rm -f $(distdir)/doc/HACKING
+
+ Two variables that come handy when writing `dist-hook' rules are
+`$(distdir)' and `$(top_distdir)'.
+
+ `$(distdir)' points to the directory where the `dist' rule will copy
+files from the current directory before creating the tarball. If you
+are at the top-level directory, then `distdir = $(PACKAGE)-$(VERSION)'.
+When used from subdirectory named `foo/', then `distdir =
+../$(PACKAGE)-$(VERSION)/foo'. `$(distdir)' can be a relative or
+absolute path, do not assume any form.
+
+ `$(top_distdir)' always points to the root directory of the
+distributed tree. At the top-level it's equal to `$(distdir)'. In the
+`foo/' subdirectory `top_distdir = ../$(PACKAGE)-$(VERSION)'.
+`$(top_distdir)' too can be a relative or absolute path.
+
+ Note that when packages are nested using `AC_CONFIG_SUBDIRS' (*note
+Subpackages::), then `$(distdir)' and `$(top_distdir)' are relative to
+the package where `make dist' was run, not to any sub-packages involved.

+
+14.4 Checking the Distribution
+==============================
+
+Automake also generates a `distcheck' rule that can be of help to
+ensure that a given distribution will actually work. Simplifying a
+bit, we can say this rule first makes a distribution, and then,
+_operating from it_, takes the following steps:
+ * tries to do a `VPATH' build (*note VPATH Builds::), with the
+ `srcdir' and all its content made _read-only_;
+
+ * runs the test suite (with `make check') on this fresh build;
+
+ * installs the package in a temporary directory (with `make
+ install'), and tries runs the test suite on the resulting
+ installation (with `make installcheck');
+
+ * checks that the package can be correctly uninstalled (by `make
+ uninstall') and cleaned (by `make distclean');
+
+ * finally, makes another tarball to ensure the distribution is
+ self-contained.
+
+DISTCHECK_CONFIGURE_FLAGS
+-------------------------
+
+Building the package involves running `./configure'. If you need to
+supply additional flags to `configure', define them in the
+`AM_DISTCHECK_CONFIGURE_FLAGS' variable in your top-level
+`Makefile.am'. The user can still extend or override the flags
+provided there by defining the `DISTCHECK_CONFIGURE_FLAGS' variable, on
+the command line when invoking `make'.
+
+ Still, developers are encouraged to strive to make their code
+buildable without requiring any special configure option; thus, in
+general, you shouldn't define `AM_DISTCHECK_CONFIGURE_FLAGS'. However,
+there might be few scenarios in which the use of this variable is
+justified. GNU `m4' offers an example. GNU `m4' configures by default
+with its experimental and seldom used "changeword" feature disabled; so
+in its case it is useful to have `make distcheck' run configure with
+the `--with-changeword' option, to ensure that the code for changeword
+support still compiles correctly. GNU `m4' also employs the
+`AM_DISTCHECK_CONFIGURE_FLAGS' variable to stress-test the use of
+`--program-prefix=g', since at one point the `m4' build system had a
+bug where `make installcheck' was wrongly assuming it could blindly
+test "`m4'", rather than the just-installed "`gm4'".
+
+distcheck-hook
+--------------
+
+If the `distcheck-hook' rule is defined in your top-level
+`Makefile.am', then it will be invoked by `distcheck' after the new
+distribution has been unpacked, but before the unpacked copy is
+configured and built. Your `distcheck-hook' can do almost anything,
+though as always caution is advised. Generally this hook is used to
+check for potential distribution errors not caught by the standard
+mechanism. Note that `distcheck-hook' as well as
+`AM_DISTCHECK_CONFIGURE_FLAGS' and `DISTCHECK_CONFIGURE_FLAGS' are not
+honored in a subpackage `Makefile.am', but the flags from
+`AM_DISTCHECK_CONFIGURE_FLAGS' and `DISTCHECK_CONFIGURE_FLAGS' are
+passed down to the `configure' script of the subpackage.
+
+distcleancheck
+--------------
+
+Speaking of potential distribution errors, `distcheck' also ensures
+that the `distclean' rule actually removes all built files. This is
+done by running `make distcleancheck' at the end of the `VPATH' build.
+By default, `distcleancheck' will run `distclean' and then make sure
+the build tree has been emptied by running
+`$(distcleancheck_listfiles)'. Usually this check will find generated
+files that you forgot to add to the `DISTCLEANFILES' variable (*note
+Clean::).
+
+ The `distcleancheck' behavior should be OK for most packages,
+otherwise you have the possibility to override the definition of either
+the `distcleancheck' rule, or the `$(distcleancheck_listfiles)'
+variable. For instance, to disable `distcleancheck' completely, add
+the following rule to your top-level `Makefile.am':
+
+ distcleancheck:
+ @:
+
+ If you want `distcleancheck' to ignore built files that have not
+been cleaned because they are also part of the distribution, add the
+following definition instead:
+
+ distcleancheck_listfiles = \
+ find . -type f -exec sh -c 'test -f $(srcdir)/$$1 || echo $$1' \
+ sh '{}' ';'
+
+ The above definition is not the default because it's usually an
+error if your Makefiles cause some distributed files to be rebuilt when
+the user build the package. (Think about the user missing the tool
+required to build the file; or if the required tool is built by your
+package, consider the cross-compilation case where it can't be run.)
+There is an entry in the FAQ about this (*note Errors with
+distclean::), make sure you read it before playing with
+`distcleancheck_listfiles'.
+
+distuninstallcheck
+------------------
+
+`distcheck' also checks that the `uninstall' rule works properly, both
+for ordinary and `DESTDIR' builds. It does this by invoking `make
+uninstall', and then it checks the install tree to see if any files are
+left over. This check will make sure that you correctly coded your
+`uninstall'-related rules.
+
+ By default, the checking is done by the `distuninstallcheck' rule,
+and the list of files in the install tree is generated by
+`$(distuninstallcheck_listfiles)' (this is a variable whose value is a
+shell command to run that prints the list of files to stdout).
+
+ Either of these can be overridden to modify the behavior of
+`distcheck'. For instance, to disable this check completely, you would
+write:
+
+ distuninstallcheck:
+ @:

+
+14.5 The Types of Distributions
+===============================
+
+Automake generates rules to provide archives of the project for
+distributions in various formats. Their targets are:
+
+`dist-bzip2'
+ Generate a bzip2 tar archive of the distribution. bzip2 archives
+ are frequently smaller than gzipped archives. By default, this
+ rule makes `bzip2' use a compression option of `-9'. To make it
+ use a different one, set the `BZIP2' environment variable. For
+ example, `make dist-bzip2 BZIP2=-7'.
+
+`dist-gzip'
+ Generate a gzip tar archive of the distribution.
+
+`dist-lzip'
+ Generate an `lzip' tar archive of the distribution. `lzip'
+ archives are frequently smaller than `bzip2'-compressed archives.
+
+`dist-shar'
+ Generate a shar archive of the distribution.
+
+`dist-xz'
+ Generate an `xz' tar archive of the distribution. `xz' archives
+ are frequently smaller than `bzip2'-compressed archives. By
+ default, this rule makes `xz' use a compression option of `-e'.
+ To make it use a different one, set the `XZ_OPT' environment
+ variable. For example, run this command to use the default
+ compression ratio, but with a progress indicator: `make dist-xz
+ XZ_OPT=-7e'.
+
+`dist-zip'
+ Generate a zip archive of the distribution.
+
+`dist-tarZ'
+ Generate a compressed tar archive of the distribution.
+
+ The rule `dist' (and its historical synonym `dist-all') will create
+archives in all the enabled formats, *note Options::. By default, only
+the `dist-gzip' target is hooked to `dist'.

+15 Support for test suites
+**************************
+
+Automake can generate code to handle two kinds of test suites. One is
+based on integration with the `dejagnu' framework. The other (and most
+used) form is based on the use of generic test scripts, and its
+activation is triggered by the definition of the special `TESTS'
+variable. This second form allows for various degrees of sophistication
+and customization; in particular, it allows for concurrent execution of
+test scripts, use of established test protocols such as TAP, and
+definition of custom test drivers and test runners.
+
+In either case, the testsuite is invoked via `make check'.

+
+15.1 Generalities about Testing
+===============================
+
+The purpose of testing is to determine whether a program or system
+behaves as expected (e.g., known inputs produce the expected outputs,
+error conditions are correctly handled or reported, and older bugs do
+not resurface).
+
+ The minimal unit of testing is usually called _test case_, or simply
+_test_. How a test case is defined or delimited, and even what exactly
+_constitutes_ a test case, depends heavily on the testing paradigm
+and/or framework in use, so we won't attempt any more precise
+definition. The set of the test cases for a given program or system
+constitutes its _testsuite_.
+
+ A _test harness_ (also _testsuite harness_) is a program or software
+component that executes all (or part of) the defined test cases,
+analyzes their outcomes, and report or register these outcomes
+appropriately. Again, the details of how this is accomplished (and how
+the developer and user can influence it or interface with it) varies
+wildly, and we'll attempt no precise definition.
+
+ A test is said to _pass_ when it can determine that the condition or
+behaviour it means to verify holds, and is said to _fail_ when it can
+determine that such condition of behaviour does _not_ hold.
+
+ Sometimes, tests can rely on non-portable tools or prerequisites, or
+simply make no sense on a given system (for example, a test checking a
+Windows-specific feature makes no sense on a GNU/Linux system). In this
+case, accordingly to the definition above, the tests can neither be
+considered passed nor failed; instead, they are _skipped_ - i.e., they
+are not run, or their result is anyway ignored for what concerns the
+count of failures an successes. Skips are usually explicitly reported
+though, so that the user will be aware that not all of the testsuite
+has really run.
+
+ It's not uncommon, especially during early development stages, that
+some tests fail for known reasons, and that the developer doesn't want
+to tackle these failures immediately (this is especially true when the
+failing tests deal with corner cases). In this situation, the better
+policy is to declare that each of those failures is an _expected
+failure_ (or _xfail_). In case a test that is expected to fail ends up
+passing instead, many testing environments will flag the result as a
+special kind of failure called _unexpected pass_ (or _xpass_).
+
+ Many testing environments and frameworks distinguish between test
+failures and hard errors. As we've seen, a test failure happens when
+some invariant or expected behaviour of the software under test is not
+met. An _hard error_ happens when e.g., the set-up of a test case
+scenario fails, or when some other unexpected or highly undesirable
+condition is encountered (for example, the program under test
+experiences a segmentation fault).

+
+15.2.1 Scripts-based Testsuites
+-------------------------------
+
+If the special variable `TESTS' is defined, its value is taken to be a
+list of programs or scripts to run in order to do the testing. Under
+the appropriate circumstances, it's possible for `TESTS' to list also
+data files to be passed to one or more test scripts defined by
+different means (the so-called "log compilers", *note Parallel Test
+Harness::).
+
+ Test scripts can be executed serially or concurrently. Automake
+supports both these kinds of test execution, with the serial test
+harness being the default (for backward-compatibility reasons only, as
+its use is nowadays discouraged). The concurrent test harness relies
+on the concurrence capabilities (if any) offered by the underlying
+`make' implementation, and can thus only be as good as those are.
+
+ By default, only the exit statuses of the test scripts are
+considered when determining the testsuite outcome. But Automake allows
+also the use of more complex test protocols, either standard (*note
+Using the TAP test protocol::) or custom (*note Custom Test Drivers::).
+Note that you can enable such protocols only when the parallel harness
+is used: they won't work with the serial test harness. In the rest of
+this section we are going to concentrate mostly on protocol-less tests,
+since we cover test protocols in a later section (again, *note Custom
+Test Drivers::).
+
+ When no test protocol is in use, an exit status of 0 from a test
+script will denote a success, an exit status of 77 a skipped test, an
+exit status of 99 an hard error, and any other exit status will denote
+a failure.
+
+ You may define the variable `XFAIL_TESTS' to a list of tests
+(usually a subset of `TESTS') that are expected to fail; this will
+effectively reverse the result of those tests (with the provision that
+skips and hard errors remain untouched). You may also instruct the
+testsuite harness to treat hard errors like simple failures, by defining
+the `DISABLE_HARD_ERRORS' make variable to a nonempty value.
+
+ Note however that, for tests based on more complex test protocols,
+the exact effects of `XFAIL_TESTS' and `DISABLE_HARD_ERRORS' might
+change, or they might even have no effect at all (for example, in tests
+using TAP, there is not way to disable hard errors, and the
+`DISABLE_HARD_ERRORS' variable has no effect on them).
+
+ The result of each test case run by the scripts in `TESTS' will be
+printed on standard output, along with the test name. For test
+protocols that allow more test cases per test script (such as TAP), a
+number, identifier and/or brief description specific for the single
+test case is expected to be printed in addition to the name of the test
+script. The possible results (whose meanings should be clear from the
+previous *note Generalities about Testing::) are `PASS', `FAIL',
+`SKIP', `XFAIL', `XPASS' and `ERROR'. Here is an example of output
+from an hypothetical testsuite that uses both plain and TAP tests:
+ PASS: foo.sh
+ PASS: zardoz.tap 1 - Daemon started
+ PASS: zardoz.tap 2 - Daemon responding
+ SKIP: zardoz.tap 3 - Daemon uses /proc # SKIP /proc is not mounted
+ PASS: zardoz.tap 4 - Daemon stopped
+ SKIP: bar.sh
+ PASS: mu.tap 1
+ XFAIL: mu.tap 2 # TODO frobnication not yet implemented
+
+A testsuite summary (expected to report at least the number of run,
+skipped and failed tests) will be printed at the end of the testsuite
+run.
+
+ If the Automake option `color-tests' is used (*note Options::) and
+standard output is connected to a capable terminal, then the test
+results and the summary are colored appropriately. The user can disable
+colored output by setting the `make' variable `AM_COLOR_TESTS=no', or
+force colored output even without a connecting terminal with
+`AM_COLOR_TESTS=always'. It's also worth noting that some `make'
+implementations, when used in parallel mode, have slightly different
+semantics (*note Parallel make: (autoconf)Parallel make.), which can
+break the automatic detection of a connection to a capable terminal.
+If this is the case, you'll have to resort to the use of
+`AM_COLOR_TESTS=always' in order to have the testsuite output colorized.
+
+ Test programs that need data files should look for them in `srcdir'
+(which is both a make variable and an environment variable made
+available to the tests), so that they work when building in a separate
+directory (*note Build Directories: (autoconf)Build Directories.), and
+in particular for the `distcheck' rule (*note Checking the
+Distribution::).
+
+ The `AM_TESTS_ENVIRONMENT' and `TESTS_ENVIRONMENT' variables can be
+used to run initialization code and set environment variables for the
+test scripts. The former variable is developer-reserved, and can be
+defined in the `Makefile.am', while the latter is reserved for the
+user, which can employ it to extend or override the settings in the
+former; for this to work portably, however, the contents of a non-empty
+`AM_TESTS_ENVIRONMENT' _must_ be terminated by a semicolon.
+
+ The `AM_TESTS_FD_REDIRECT' variable can be used to define file
+descriptor redirections for the test scripts. One might think that
+`AM_TESTS_ENVIRONMENT' could be used for this purpose, but experience
+has shown that doing so portably is practically impossible. The main
+hurdle is constituted by Korn shells, which usually set the
+close-on-exec flag on file descriptors opened with the `exec' builtin,
+thus rendering an idiom like `AM_TESTS_ENVIRONMENT = exec 9>&2;'
+ineffectual. This issue also affects some Bourne shells, such as the
+HP-UX's `/bin/sh',
+
+ AM_TESTS_ENVIRONMENT = \
+ ## Some environment initializations are kept in a separate shell
+ ## file `tests-env.sh', which can make it easier to also run tests
+ ## from the command line.
+ . $(srcdir)/tests-env.sh; \
+ ## On Solaris, prefer more POSIX-compliant versions of the standard
+ ## tools by default.
+ if test -d /usr/xpg4/bin; then \
+ PATH=/usr/xpg4/bin:$$PATH; export PATH; \
+ fi;
+ ## With this, the test scripts will be able to print diagnostic
+ ## messages to the original standard error stream, even if the test
+ ## driver redirects the stderr of the test scripts to a log file
+ ## before executing them.
+ AM_TESTS_FD_REDIRECT = 9>&2
+
+Note however that `AM_TESTS_ENVIRONMENT' is, for historical and
+implementation reasons, _not_ supported by the serial harness (*note
+Serial Test Harness::).
+
+ Automake ensures that each file listed in `TESTS' is built before it
+is run; you can list both source and derived programs (or scripts) in
+`TESTS'; the generated rule will look both in `srcdir' and `.'. For
+instance, you might want to run a C program as a test. To do this you
+would list its name in `TESTS' and also in `check_PROGRAMS', and then
+specify it as you would any other program.
+
+ Programs listed in `check_PROGRAMS' (and `check_LIBRARIES',
+`check_LTLIBRARIES'...) are only built during `make check', not during
+`make all'. You should list there any program needed by your tests
+that does not need to be built by `make all'. Note that
+`check_PROGRAMS' are _not_ automatically added to `TESTS' because
+`check_PROGRAMS' usually lists programs used by the tests, not the
+tests themselves. Of course you can set `TESTS = $(check_PROGRAMS)' if
+all your programs are test cases.

+
+15.2.2 Serial Test Harness
+--------------------------
+
+_NOTE:_ This harness, while still being the default one, is
+obsolescent, and kept mostly for backward-compatibility reasons. The
+user is advised to use the parallel test harness instead (*note
+Parallel Test Harness::). Be warned that future Automake versions
+might switch to use that more modern and feature-rich harness by
+default.
+
+ The serial test harness is enabled by the Automake option
+`serial-tests'. It operates by simply running the tests serially, one
+at the time, without any I/O redirection. It's up to the user to
+implement logging of tests' output, if that's requited or desired.
+
+ For historical and implementation reasons, the `AM_TESTS_ENVIRONMENT'
+variable is _not_ supported by this harness (it will be silently
+ignored if defined); only `TESTS_ENVIRONMENT' is, and it is to be
+considered a developer-reserved variable. This is done so that, when
+using the serial harness, `TESTS_ENVIRONMENT' can be defined to an
+invocation of an interpreter through which the tests are to be run.
+For instance, the following setup may be used to run tests with Perl:
+
+ TESTS_ENVIRONMENT = $(PERL) -Mstrict -w
+ TESTS = foo.pl bar.pl baz.pl
+
+It's important to note that the use of `TESTS_ENVIRONMENT' endorsed
+here would be _invalid_ with the parallel harness. That harness
+provides a more elegant way to achieve the same effect, with the further
+benefit of freeing the `TESTS_ENVIRONMENT' variable for the user (*note
+Parallel Test Harness::).
+
+ Another, less serious limit of the serial harness is that it doesn't
+really distinguish between simple failures and hard errors; this is due
+to historical reasons only, and might be fixed in future Automake
+versions.
+
+\1f
+File: automake.info, Node: Parallel Test Harness, Prev: Serial Test Harness, Up: Simple Tests
+
+15.2.3 Parallel Test Harness
+----------------------------
+
+The parallel (or concurrent) test harness is enabled by the Automake
+option `parallel-tests'. It features automatic collection of the test
+scripts output in `.log' files, concurrent execution of tests with
+`make -j', specification of inter-test dependencies, lazy reruns of
+tests that have not completed in a prior run, and hard errors for
+exceptional failures.
+
+ This harness is still somewhat experimental and may undergo changes
+in order to satisfy additional portability requirements.
+
+ The parallel test harness operates by defining a set of `make' rules
+that run the test scripts listed in `TESTS', and, for each such script,
+save its output in a corresponding `.log' file and its results (and
+other "metadata", *note API for Custom Test Drivers::) in a
+corresponding `.trs' (as in Test ReSults) file. The `.log' file will
+contain all the output emitted by the test on its standard output and
+its standard error. The `.trs' file will contain, among the other
+things, the results of the test cases run by the script.
+
+ The parallel test harness will also create a summary log file,
+`TEST_SUITE_LOG', which defaults to `test-suite.log' and requires a
+`.log' suffix. This file depends upon all the `.log' and `.trs' files
+created for the test scripts listed in `TESTS'.
+
+ As with the serial harness above, by default one status line is
+printed per completed test, and a short summary after the suite has
+completed. However, standard output and standard error of the test are
+redirected to a per-test log file, so that parallel execution does not
+produce intermingled output. The output from failed tests is collected
+in the `test-suite.log' file. If the variable `VERBOSE' is set, this
+file is output after the summary. For best results, the tests should
+be verbose by default now.
+
+ Each couple of `.log' and `.trs' files is created when the
+corresponding test has completed. The set of log files is listed in
+the read-only variable `TEST_LOGS', and defaults to `TESTS', with the
+executable extension if any (*note EXEEXT::), as well as any suffix
+listed in `TEST_EXTENSIONS' removed, and `.log' appended. Results are
+undefined if a test file name ends in several concatenated suffixes.
+`TEST_EXTENSIONS' defaults to `.test'; it can be overridden by the
+user, in which case any extension listed in it must be constituted by a
+dot, followed by a non-digit alphabetic character, followed by any
+number of alphabetic characters. For example, `.sh', `.T' and `.t1'
+are valid extensions, while `.x-y', `.6c' and `.t.1' are not.
+
+ For tests that match an extension `.EXT' listed in
+`TEST_EXTENSIONS', you can provide a custom "test runner" using the
+variable `EXT_LOG_COMPILER' (note the upper-case extension) and pass
+options in `AM_EXT_LOG_FLAGS' and allow the user to pass options in
+`EXT_LOG_FLAGS'. It will cause all tests with this extension to be
+called with this runner. For all tests without a registered extension,
+the variables `LOG_COMPILER', `AM_LOG_FLAGS', and `LOG_FLAGS' may be
+used. For example,
+
+ TESTS = foo.pl bar.py baz
+ TEST_EXTENSIONS = .pl .py
+ PL_LOG_COMPILER = $(PERL)
+ AM_PL_LOG_FLAGS = -w
+ PY_LOG_COMPILER = $(PYTHON)
+ AM_PY_LOG_FLAGS = -v
+ LOG_COMPILER = ./wrapper-script
+ AM_LOG_FLAGS = -d
+
+will invoke `$(PERL) -w foo.pl', `$(PYTHON) -v bar.py', and
+`./wrapper-script -d baz' to produce `foo.log', `bar.log', and
+`baz.log', respectively. The `foo.trs', `bar.trs' and `baz.trs' files
+will be automatically produced as a side-effect.
+
+ It's important to note that, differently from what we've seen for the
+serial test harness (*note Parallel Test Harness::), the
+`AM_TESTS_ENVIRONMENT' and `TESTS_ENVIRONMENT' variables _cannot_ be
+use to define a custom test runner; the `LOG_COMPILER' and `LOG_FLAGS'
+(or their extension-specific counterparts) should be used instead:
+
+ ## This is WRONG!
+ AM_TESTS_ENVIRONMENT = PERL5LIB='$(srcdir)/lib' $(PERL) -Mstrict -w
+
+ ## Do this instead.
+ AM_TESTS_ENVIRONMENT = PERL5LIB='$(srcdir)/lib'; export PERL5LIB;
+ LOG_COMPILER = $(PERL)
+ AM_LOG_FLAGS = -Mstrict -w
+
+ By default, the test suite harness will run all tests, but there are
+several ways to limit the set of tests that are run:
+
+ * You can set the `TESTS' variable. For example, you can use a
+ command like this to run only a subset of the tests:
+
+ env TESTS="foo.test bar.test" make -e check
+
+ Note however that the command above will unconditionally overwrite
+ the `test-suite.log' file, thus clobbering the recorded results of
+ any previous testsuite run. This might be undesirable for packages
+ whose testsuite takes long time to execute. Luckily, this problem
+ can easily be avoided by overriding also `TEST_SUITE_LOG' at
+ runtime; for example,
+
+ env TEST_SUITE_LOG=partial.log TESTS="..." make -e check
+
+ will write the result of the partial testsuite runs to the
+ `partial.log', without touching `test-suite.log'.
+
+ * You can set the `TEST_LOGS' variable. By default, this variable is
+ computed at `make' run time from the value of `TESTS' as described
+ above. For example, you can use the following:
+
+ set x subset*.log; shift
+ env TEST_LOGS="foo.log $*" make -e check
+
+ The comments made above about `TEST_SUITE_LOG' overriding applies
+ here too.
+
+ * By default, the test harness removes all old per-test `.log' and
+ `.trs' files before it starts running tests to regenerate them.
+ The variable `RECHECK_LOGS' contains the set of `.log' (and, by
+ implication, `.trs') files which are removed. `RECHECK_LOGS'
+ defaults to `TEST_LOGS', which means all tests need to be
+ rechecked. By overriding this variable, you can choose which
+ tests need to be reconsidered. For example, you can lazily rerun
+ only those tests which are outdated, i.e., older than their
+ prerequisite test files, by setting this variable to the empty
+ value:
+
+ env RECHECK_LOGS= make -e check
+
+ * You can ensure that all tests are rerun which have failed or passed
+ unexpectedly, by running `make recheck' in the test directory.
+ This convenience target will set `RECHECK_LOGS' appropriately
+ before invoking the main test harness.
+
+In order to guarantee an ordering between tests even with `make -jN',
+dependencies between the corresponding `.log' files may be specified
+through usual `make' dependencies. For example, the following snippet
+lets the test named `foo-execute.test' depend upon completion of the
+test `foo-compile.test':
+
+ TESTS = foo-compile.test foo-execute.test
+ foo-execute.log: foo-compile.log
+
+Please note that this ordering ignores the _results_ of required tests,
+thus the test `foo-execute.test' is run even if the test
+`foo-compile.test' failed or was skipped beforehand. Further, please
+note that specifying such dependencies currently works only for tests
+that end in one of the suffixes listed in `TEST_EXTENSIONS'.
+
+ Tests without such specified dependencies may be run concurrently
+with parallel `make -jN', so be sure they are prepared for concurrent
+execution.
+
+ The combination of lazy test execution and correct dependencies
+between tests and their sources may be exploited for efficient unit
+testing during development. To further speed up the edit-compile-test
+cycle, it may even be useful to specify compiled programs in
+`EXTRA_PROGRAMS' instead of with `check_PROGRAMS', as the former allows
+intertwined compilation and test execution (but note that
+`EXTRA_PROGRAMS' are not cleaned automatically, *note Uniform::).
+
+ The variables `TESTS' and `XFAIL_TESTS' may contain conditional
+parts as well as configure substitutions. In the latter case, however,
+certain restrictions apply: substituted test names must end with a
+nonempty test suffix like `.test', so that one of the inference rules
+generated by `automake' can apply. For literal test names, `automake'
+can generate per-target rules to avoid this limitation.
+
+ Please note that it is currently not possible to use `$(srcdir)/' or
+`$(top_srcdir)/' in the `TESTS' variable. This technical limitation is
+necessary to avoid generating test logs in the source tree and has the
+unfortunate consequence that it is not possible to specify distributed
+tests that are themselves generated by means of explicit rules, in a
+way that is portable to all `make' implementations (*note Make Target
+Lookup: (autoconf)Make Target Lookup, the semantics of FreeBSD and
+OpenBSD `make' conflict with this). In case of doubt you may want to
+require to use GNU `make', or work around the issue with inference
+rules to generate the tests.

+
+15.3.1 Overview of Custom Test Drivers Support
+----------------------------------------------
+
+Starting from Automake version 1.12, the parallel test harness allows
+the package authors to use third-party custom test drivers, in case the
+default ones are inadequate for their purposes, or do not support their
+testing protocol of choice.
+
+ A custom test driver is expected to properly run the test programs
+passed to it (including the command-line arguments passed to those
+programs, if any), to analyze their execution and outcome, to create
+the `.log' and `.trs' files associated to these test runs, and to
+display the test results on the console. It is responsibility of the
+author of the test driver to ensure that it implements all the above
+steps meaningfully and correctly; Automake isn't and can't be of any
+help here. On the other hand, the Automake-provided code for testsuite
+summary generation offers support for test drivers allowing several
+test results per test script, if they take care to register such
+results properly (*note Log files generation and test results
+recording::).
+
+ The exact details of how test scripts' results are to be determined
+and analyzed is left to the individual drivers. Some drivers might only
+consider the test script exit status (this is done for example by the
+default test driver used by the parallel test harness, described in the
+previous section). Other drivers might implement more complex and
+advanced test protocols, which might require them to parse and
+interpreter the output emitted by the test script they're running
+(examples of such protocols are TAP and SubUnit).
+
+ It's very important to note that, even when using custom test
+drivers, most of the infrastructure described in the previous section
+about the parallel harness remains in place; this includes:
+
+ * list of test scripts defined in `TESTS', and overridable at
+ runtime through the redefinition of `TESTS' or `TEST_LOGS';
+
+ * concurrency through the use of `make''s option `-j';
+
+ * per-test `.log' and `.trs' files, and generation of a summary
+ `.log' file from them;
+
+ * `recheck' target, `RECHECK_LOGS' variable, and lazy reruns of
+ tests;
+
+ * inter-test dependencies;
+
+ * support for `check_*' variables (`check_PROGRAMS',
+ `check_LIBRARIES', ...);
+
+ * use of `VERBOSE' environment variable to get verbose output on
+ testsuite failures;
+
+ * definition and honoring of `TESTS_ENVIRONMENT',
+ `AM_TESTS_ENVIRONMENT' and `AM_TESTS_FD_REDIRECT' variables;
+
+ * definition of generic and extension-specific `LOG_COMPILER' and
+ `LOG_FLAGS' variables.
+
+On the other hand, the exact semantics of how (and if) `color-tests',
+`XFAIL_TESTS', and hard errors are supported and handled is left to the
+individual test drivers.

+
+15.3.2 Declaring Custom Test Drivers
+------------------------------------
+
+Custom testsuite drivers are declared by defining the make variables
+`LOG_DRIVER' or `EXT_LOG_DRIVER' (where EXT must be declared in
+`TEST_EXTENSIONS'). They must be defined to programs or scripts that
+will be used to drive the execution, logging, and outcome report of the
+tests with corresponding extensions (or of those with no registered
+extension in the case of `LOG_DRIVER'). Clearly, multiple distinct
+test drivers can be declared in the same `Makefile.am'. Note moreover
+that the `LOG_DRIVER' variables are _not_ a substitute for the
+`LOG_COMPILER' variables: the two sets of variables can, and often do,
+usefully and legitimately coexist.
+
+ The developer-reserved variable `AM_LOG_DRIVER_FLAGS' and the
+user-reserved variable `LOG_DRIVER_FLAGS' can be used to define flags
+that will be passed to each invocation of `LOG_DRIVER', with the
+user-defined flags obviously taking precedence over the
+developer-reserved ones. Similarly, for each extension EXT declared in
+`TEST_EXTENSIONS', flags listed in `AM_EXT_LOG_DRIVER_FLAGS' and
+`EXT_LOG_DRIVER_FLAGS' will be passed to invocations of
+`EXT_LOG_DRIVER'.

+
+Note that _the APIs described here are still highly experimental_, and
+will very likely undergo tightenings and likely also extensive changes
+in the future, to accommodate for new features or to satisfy additional
+portability requirements.
+
+ The main characteristic of these APIs is that they are designed to
+share as much infrastructure, semantics, and implementation details as
+possible with the parallel test harness and its default driver.

+
+15.3.3.1 Command-line arguments for test drivers
+................................................
+
+A custom driver can rely on various command-line options and arguments
+being passed to it automatically by the Automake's `parallel-tests'
+harness. It is _mandatory_ that it understands all of them (even if
+the exact interpretation of the associated semantics can legitimately
+change between a test driver and another, and even be a no-op in some
+drivers).
+
+Here is the list of options:
+
+`--test-name=NAME'
+ The name of the test, with VPATH prefix (if any) removed. This
+ can have a suffix and a directory component (as in e.g.,
+ `sub/foo.test'), and is mostly meant to be used in console reports
+ about testsuite advancements and results (*note Testsuite progress
+ output::).
+
+`--log-file=`PATH.log''
+ The `.log' file the test driver must create (*note Basics of test
+ metadata::). If it has a directory component (as in e.g.,
+ `sub/foo.log'), the test harness will ensure that such directory
+ exists _before_ the test driver is called.
+
+`--trs-file=`PATH.trs''
+ The `.trs' file the test driver must create (*note Basics of test
+ metadata::). If it has a directory component (as in e.g.,
+ `sub/foo.trs'), the test harness will ensure that such directory
+ exists _before_ the test driver is called.
+
+`--color-tests={yes|no}'
+ Whether the console output should be colorized or not (*note
+ Simple tests and color-tests::, to learn when this option gets
+ activated and when it doesn't).
+
+`--expect-failure={yes|no}'
+ Whether the tested program is expected to fail.
+
+`--enable-hard-errors={yes|no}'
+ Whether "hard errors" in the tested program should be treated
+ differently from normal failures or not (the default should be
+ `yes'). The exact meaning of "hard error" is highly dependent
+ from the test protocols or conventions in use.
+
+`--'
+ Explicitly terminate the list of options.
+
+The first non-option argument passed to the test driver is the program
+to be run, and all the following ones are command-line options and
+arguments for this program.
+
+ Note that the exact semantics attached to the `--color-tests',
+`--expect-failure' and `--enable-hard-errors' options are left up to
+the individual test drivers. Still, having a behaviour compatible or
+at least similar to that provided by the default `parallel-tests'
+driver is advised, as that would offer a better consistency and a more
+pleasant user experience.
+

+
+15.3.3.2 Log files generation and test results recording
+........................................................
+
+The test driver must correctly generate the files specified by the
+`--log-file' and `--trs-file' option (even when the tested program
+fails or crashes).
+
+ The `.log' file should ideally contain all the output produced by the
+tested program, plus optionally other information that might facilitate
+debugging or analysis of bug reports. Apart from that, its format is
+basically free.
+
+ The `.trs' file is used to register some metadata through the use of
+custom reStructuredText fields. This metadata is expected to be
+employed in various ways by the parallel test harness; for example, to
+count the test results when printing the testsuite summary, or to decide
+which tests to re-run upon `make reheck'. Unrecognized metadata in a
+`.trs' file is currently ignored by the harness, but this might change
+in the future. The list of currently recognized metadata follows.
+
+`:test-result:'
+ The test driver must use this field to register the results of
+ _each_ test case run by a test script file. Several
+ `:test-result:' fields can be present in the same `.trs' file;
+ this is done in order to support test protocols that allow a
+ single test script to run more test cases.
+
+ The only recognized test results are currently `PASS', `XFAIL',
+ `SKIP', `FAIL', `XPASS' and `ERROR'. These results, when declared
+ with `:test-result:', can be optionally followed by text holding
+ the name and/or a brief description of the corresponding test; the
+ `parallel-tests' harness will ignore such extra text when
+ generating `test-suite.log' and preparing the testsuite summary.
+
+``:recheck:''
+ If this field is present and defined to `no', then the
+ corresponding test script will _not_ be run upon a `make recheck'.
+ What happens when two or more `:recheck:' fields are present in
+ the same `.trs' file is undefined behaviour.
+
+``:copy-in-global-log:''
+ If this field is present and defined to `no', then the content of
+ the `.log' file will _not_ be copied into the global
+ `test-suite.log'. We allow to forsake such copying because, while
+ it can be useful in debugging and analysis of bug report, it can
+ also be just a waste of space in normal situations, e.g., when a
+ test script is successful. What happens when two or more
+ `:copy-in-global-log:' fields are present in the same `.trs' file
+ is undefined behaviour.
+
+``:test-global-result:''
+ This is used to declare the "global result" of the script.
+ Currently, the value of this field is needed only to be reported
+ (more or less verbatim) in the generated global log file
+ `$(TEST_SUITE_LOG)', so it's quite free-form. For example, a test
+ script which run 10 test cases, 6 of which pass and 4 of which are
+ skipped, could reasonably have a `PASS/SKIP' value for this field,
+ while a test script which run 19 successful tests and one failed
+ test could have an `ALMOST PASSED' value. What happens when two
+ or more `:test-global-result:' fields are present in the same
+ `.trs' file is undefined behaviour.
+
+Let's see a small example. Assume a `.trs' file contains the following
+lines:
+
+ :test-result: PASS server starts
+ :global-log-copy: no
+ :test-result: PASS HTTP/1.1 request
+ :test-result: FAIL HTTP/1.0 request
+ :recheck: yes
+ :test-result: SKIP HTTPS request (TLS library wasn't available)

+
+Then the corresponding test script will be re-run by `make check', will
+contribute with _five_ test results to the testsuite summary (three of
+these tests being successful, one failed, and one skipped), and the
+content of the corresponding `.log' file will _not_ be copied in the
+global log file `test-suite.log'.

+15.3.3.3 Testsuite progress output
+..................................
+
+A custom test driver also has the task of displaying, on the standard
+output, the test results as soon as they become available. Depending on
+the protocol in use, it can also display the reasons for failures and
+skips, and, more generally, any useful diagnostic output (but remember
+that each line on the screen is precious, so that cluttering the screen
+with overly verbose information is bad idea). The exact format of this
+progress output is left up to the test driver; in fact, a custom test
+driver might _theoretically_ even decide not to do any such report,
+leaving it all to the testsuite summary (that would be a very lousy
+idea, of course, and serves only to illustrate the flexibility that is
+granted here).
+
+ Remember that consistency is good; so, if possible, try to be
+consistent with the output of the built-in Automake test drivers,
+providing a similar "look & feel". In particular, the testsuite
+progress output should be colorized when the `--color-tests' is passed
+to the driver. On the other end, if you are using a known and
+widespread test protocol with well-established implementations, being
+consistent with those implementations' output might be a good idea too.

+
+15.4.1 Introduction to TAP
+--------------------------
+
+TAP, the Test Anything Protocol, is a simple text-based interface
+between testing modules or programs and a test harness. The tests
+(also called "TAP producers" in this context) write test results in a
+simple format on standard output; a test harness (also called "TAP
+consumer") will parse and interpret these results, and properly present
+them to the user, and/or register them for later analysis. The exact
+details of how this is accomplished can vary among different test
+harnesses. The Automake parallel harness will present the results on
+the console in the usual fashion (*note Testsuite progress on
+console::), and will use the `.trs' files (*note Basics of test
+metadata::) to store the test results and related metadata. Apart from
+that, it will try to remain as much compatible as possible with
+pre-existing and widespread utilities, such as the `prove' utility
+(http://search.cpan.org/~andya/Test-Harness/bin/prove), at least for
+the simpler usages.
+
+ TAP started its life as part of the test harness for Perl, but today
+it has been (mostly) standardized, and has various independent
+implementations in different languages; among them, C, C++, Perl,
+Python, PHP, and Java. For a semi-official specification of the TAP
+protocol, please refer to the documentation of `Test::Harness::TAP'
+(http://search.cpan.org/~petdance/Test-Harness/lib/Test/Harness/TAP.pod).
+
+ The most relevant real-world usages of TAP are obviously in the
+testsuites of `perl' and of many perl modules. Still, also other
+important third-party packages, such as `git' (http://git-scm.com/),
+use TAP in their testsuite.
+

+
+15.4.2 Use TAP with the Automake test harness
+---------------------------------------------
+
+Currently, the TAP driver that comes with Automake requires some by-hand
+steps on the developer's part (this situation should hopefully be
+improved in future Automake versions). You'll have to grab the
+`tap-driver.sh' script from the Automake distribution by hand, copy it
+in your source tree, add a call to `AC_PROG_AWK' in `configure.ac' to
+search for a proper awk program, and use the Automake support for
+third-party test drivers to instruct the harness to use the
+`tap-driver.sh' script and that awk program to run your TAP-producing
+tests. See the example below for clarification.
+
+ Apart from the options common to all the Automake test drivers
+(*note Command-line arguments for test drivers::), the `tap-driver.sh'
+supports the following options, whose names are chosen for enhanced
+compatibility with the `prove' utility.
+
+`--ignore-exit'
+ Causes the test driver to ignore the exit status of the test
+ scripts; by default, the driver will report an error if the script
+ exits with a non-zero status. This option has effect also on
+ non-zero exit statuses due to termination by a signal.
+
+`--comments'
+ Instruct the test driver to display TAP diagnostic (i.e., lines
+ beginning with the `#' character) in the testsuite progress output
+ too; by default, TAP diagnostic is only copied to the `.log' file.
+
+`--no-comments'
+ Revert the effects of `--comments'.
+
+`--merge'
+ Instruct the test driver to merge the test scripts' standard error
+ into their standard output. This is necessary if you want to
+ ensure that diagnostics from the test scripts are displayed in the
+ correct order relative to test results; this can be of great help
+ in debugging (especially if your test scripts are shell scripts
+ run with shell tracing active). As a downside, this option might
+ cause the test harness to get confused if anything that appears on
+ standard error looks like a test result.
+
+`--no-merge'
+ Revert the effects of `--merge'.
+
+`--diagnostic-string=STRING'
+ Change the string that introduces TAP diagnostic from the default
+ value of "`#'" to `STRING'. This can be useful if your TAP-based
+ test scripts produce verbose output on which they have limited
+ control (because, say, the output comes from other tools invoked
+ in the scripts), and it might contain text that gets spuriously
+ interpreted as TAP diagnostic: such an issue can be solved by
+ redefining the string that activates TAP diagnostic to a value you
+ know won't appear by chance in the tests' output. Note however
+ that this feature is non-standard, as the "official" TAP protocol
+ does not allow for such a customization; so don't use it if you
+ can avoid it.
+
+Here is an example of how the TAP driver can be set up and used.

+
+15.4.3 Incompatibilities with other TAP parsers and drivers
+-----------------------------------------------------------
+
+For implementation or historical reasons, the TAP driver and harness as
+implemented by Automake have some minors incompatibilities with the
+mainstream versions, which you should be aware of.
+
+ * A `Bail out!' directive doesn't stop the whole testsuite, but only
+ the test script it occurs in. This doesn't follow TAP
+ specifications, but on the other hand it maximizes compatibility
+ (and code sharing) with the "hard error" concept of the default
+ `parallel-tests' driver.
+
+ * The `version' and `pragma' directives are not supported.
+
+ * The `--diagnostic-string' option of our driver allows to modify
+ the string that introduces TAP diagnostic from the default value
+ of "`#'". The standard TAP protocol has currently no way to allow
+ this, so if you use it your diagnostic will be lost to more
+ compliant tools like `prove' and `Test::Harness'
+
+ * And there are probably some other small and yet undiscovered
+ incompatibilities, especially in corner cases or with rare usages.

+15.5 DejaGnu Tests
+==================
+
+If `dejagnu' (ftp://ftp.gnu.org/gnu/dejagnu/) appears in
+`AUTOMAKE_OPTIONS', then a `dejagnu'-based test suite is assumed. The
+variable `DEJATOOL' is a list of names that are passed, one at a time,
+as the `--tool' argument to `runtest' invocations; it defaults to the
+name of the package.
+
+ The variable `RUNTESTDEFAULTFLAGS' holds the `--tool' and `--srcdir'
+flags that are passed to dejagnu by default; this can be overridden if
+necessary.
+
+ The variables `EXPECT' and `RUNTEST' can also be overridden to
+provide project-specific values. For instance, you will need to do
+this if you are testing a compiler toolchain, because the default
+values do not take into account host and target names.
+
+ The contents of the variable `RUNTESTFLAGS' are passed to the
+`runtest' invocation. This is considered a "user variable" (*note User
+Variables::). If you need to set `runtest' flags in `Makefile.am', you
+can use `AM_RUNTESTFLAGS' instead.
+
+ Automake will generate rules to create a local `site.exp' file,
+defining various variables detected by `configure'. This file is
+automatically read by DejaGnu. It is OK for the user of a package to
+edit this file in order to tune the test suite. However this is not
+the place where the test suite author should define new variables: this
+should be done elsewhere in the real test suite code. Especially,
+`site.exp' should not be distributed.
+
+ Still, if the package author has legitimate reasons to extend
+`site.exp' at `make' time, he can do so by defining the variable
+`EXTRA_DEJAGNU_SITE_CONFIG'; the files listed there will be considered
+`site.exp' prerequisites, and their content will be appended to it (in
+the same order in which they appear in `EXTRA_DEJAGNU_SITE_CONFIG').
+Note that files are _not_ distributed by default.
+
+ For more information regarding DejaGnu test suites, see *note Top:

+15.6 Install Tests
+==================
+
+The `installcheck' target is available to the user as a way to run any
+tests after the package has been installed. You can add tests to this
+by writing an `installcheck-local' rule.
+

+File: automake.info, Node: Rebuilding, Next: Options, Prev: Tests, Up: Top
+
+16 Rebuilding Makefiles
+***********************
+
+Automake generates rules to automatically rebuild `Makefile's,
+`configure', and other derived files like `Makefile.in'.
+
+ If you are using `AM_MAINTAINER_MODE' in `configure.ac', then these
+automatic rebuilding rules are only enabled in maintainer mode.
+
+ Sometimes you need to run `aclocal' with an argument like `-I' to
+tell it where to find `.m4' files. Since sometimes `make' will
+automatically run `aclocal', you need a way to specify these arguments.
+You can do this by defining `ACLOCAL_AMFLAGS'; this holds arguments
+that are passed verbatim to `aclocal'. This variable is only useful in
+the top-level `Makefile.am'.
+
+ Sometimes it is convenient to supplement the rebuild rules for
+`configure' or `config.status' with additional dependencies. The
+variables `CONFIGURE_DEPENDENCIES' and `CONFIG_STATUS_DEPENDENCIES' can
+be used to list these extra dependencies. These variables should be
+defined in all `Makefile's of the tree (because these two rebuild rules
+are output in all them), so it is safer and easier to `AC_SUBST' them
+from `configure.ac'. For instance, the following statement will cause
+`configure' to be rerun each time `version.sh' is changed.
+
+ AC_SUBST([CONFIG_STATUS_DEPENDENCIES], ['$(top_srcdir)/version.sh'])
+
+Note the `$(top_srcdir)/' in the file name. Since this variable is to
+be used in all `Makefile's, its value must be sensible at any level in
+the build hierarchy.
+
+ Beware not to mistake `CONFIGURE_DEPENDENCIES' for
+`CONFIG_STATUS_DEPENDENCIES'.
+
+ `CONFIGURE_DEPENDENCIES' adds dependencies to the `configure' rule,
+whose effect is to run `autoconf'. This variable should be seldom
+used, because `automake' already tracks `m4_include'd files. However
+it can be useful when playing tricky games with `m4_esyscmd' or similar
+non-recommendable macros with side effects.
+
+ `CONFIG_STATUS_DEPENDENCIES' adds dependencies to the
+`config.status' rule, whose effect is to run `configure'. This
+variable should therefore carry any non-standard source that may be
+read as a side effect of running `configure', like `version.sh' in the
+example above.
+
+ Speaking of `version.sh' scripts, we recommend against them today.
+They are mainly used when the version of a package is updated
+automatically by a script (e.g., in daily builds). Here is what some
+old-style `configure.ac's may look like:
+
+ AC_INIT
+ . $srcdir/version.sh
+ AM_INIT_AUTOMAKE([name], $VERSION_NUMBER)
+ ...
+
+Here, `version.sh' is a shell fragment that sets `VERSION_NUMBER'. The
+problem with this example is that `automake' cannot track dependencies
+(listing `version.sh' in `CONFIG_STATUS_DEPENDENCIES', and distributing
+this file is up to the user), and that it uses the obsolete form of
+`AC_INIT' and `AM_INIT_AUTOMAKE'. Upgrading to the new syntax is not
+straightforward, because shell variables are not allowed in `AC_INIT''s
+arguments. We recommend that `version.sh' be replaced by an M4 file
+that is included by `configure.ac':
+
+ m4_include([version.m4])
+ AC_INIT([name], VERSION_NUMBER)
+ AM_INIT_AUTOMAKE
+ ...
+
+Here `version.m4' could contain something like
+`m4_define([VERSION_NUMBER], [1.2])'. The advantage of this second
+form is that `automake' will take care of the dependencies when
+defining the rebuild rule, and will also distribute the file
+automatically. An inconvenience is that `autoconf' will now be rerun
+each time the version number is bumped, when only `configure' had to be
+rerun in the previous setup.

+17 Changing Automake's Behavior
+*******************************

+* List of Automake options:: A comprehensive list of Automake options
+
+\1f
+File: automake.info, Node: Options generalities, Next: List of Automake options, Up: Options
+
+17.1 Options generalities
+=========================
+
+Various features of Automake can be controlled by options. Except where
+noted otherwise, options can be specified in one of several ways. Most
+options can be applied on a per-`Makefile' basis when listed in a
+special `Makefile' variable named `AUTOMAKE_OPTIONS'. Some of these
+options only make sense when specified in the toplevel `Makefile.am'
+file. Options are applied globally to all processed `Makefile' files
+when listed in the first argument of `AM_INIT_AUTOMAKE' in
+`configure.ac', and some options which require changes to the
+`configure' script can only be specified there. These are annotated
+below.
+
+ As a general rule, options specified in `AUTOMAKE_OPTIONS' take
+precedence over those specified in `AM_INIT_AUTOMAKE', which in turn
+take precedence over those specified on the command line.
+
+ Also, some care must be taken about the interactions among strictness
+level and warning categories. As a general rule, strictness-implied
+warnings are overridden by those specified by explicit options. For
+example, even if `portability' warnings are disabled by default in
+`foreign' strictness, an usage like this will end up enabling them:
+
+ AUTOMAKE_OPTIONS = -Wportability foreign
+
+ However, a strictness level specified in a higher-priority context
+will override all the explicit warnings specified in a lower-priority
+context. For example, if `configure.ac' contains:
+
+ AM_INIT_AUTOMAKE([-Wportability])
+
+and `Makefile.am' contains:
+
+ AUTOMAKE_OPTIONS = foreign
+
+then `portability' warnings will be _disabled_ in `Makefile.am'.
+

+
+17.2 List of Automake options
+=============================
+
+`gnits'
+`gnu'
+`foreign'
+`cygnus'
+ Set the strictness as appropriate. The `gnits' option also
+ implies options `readme-alpha' and `check-news'.
+
+`check-news'
+ Cause `make dist' to fail unless the current version number appears
+ in the first few lines of the `NEWS' file.
+
+`color-tests'
+ Cause output of the serial and parallel test harnesses (see *note
+ Simple Tests::) and of properly-written custom test drivers (*note
+ Custom Test Drivers::) to be colorized on capable terminals.
+
+`dejagnu'
+ Cause `dejagnu'-specific rules to be generated. *Note DejaGnu
+ Tests::.
+
+`dist-bzip2'
+ Hook `dist-bzip2' to `dist'.
+
+`dist-lzip'
+ Hook `dist-lzip' to `dist'.
+
+`dist-shar'
+ Hook `dist-shar' to `dist'.
+
+`dist-zip'
+ Hook `dist-zip' to `dist'.
+
+`dist-tarZ'
+ Hook `dist-tarZ' to `dist'.
+
+`filename-length-max=99'
+ Abort if file names longer than 99 characters are found during
+ `make dist'. Such long file names are generally considered not to
+ be portable in tarballs. See the `tar-v7' and `tar-ustar' options
+ below. This option should be used in the top-level `Makefile.am'
+ or as an argument of `AM_INIT_AUTOMAKE' in `configure.ac', it will
+ be ignored otherwise. It will also be ignored in sub-packages of
+ nested packages (*note Subpackages::).
+
+`no-define'
+ This option is meaningful only when passed as an argument to
+ `AM_INIT_AUTOMAKE'. It will prevent the `PACKAGE' and `VERSION'
+ variables from being `AC_DEFINE'd.
+
+`no-dependencies'
+ This is similar to using `--ignore-deps' on the command line, but
+ is useful for those situations where you don't have the necessary
+ bits to make automatic dependency tracking work (*note
+ Dependencies::). In this case the effect is to effectively
+ disable automatic dependency tracking.
+
+`no-dist'
+ Don't emit any code related to `dist' target. This is useful when
+ a package has its own method for making distributions.
+
+`no-dist-gzip'
+ Do not hook `dist-gzip' to `dist'.
+
+`no-exeext'
+ If your `Makefile.am' defines a rule for target `foo', it will
+ override a rule for a target named `foo$(EXEEXT)'. This is
+ necessary when `EXEEXT' is found to be empty. However, by default
+ `automake' will generate an error for this use. The `no-exeext'
+ option will disable this error. This is intended for use only
+ where it is known in advance that the package will not be ported
+ to Windows, or any other operating system using extensions on
+ executables.
+
+`no-installinfo'
+ The generated `Makefile.in' will not cause info pages to be built
+ or installed by default. However, `info' and `install-info'
+ targets will still be available. This option is disallowed at
+ `gnu' strictness and above.
+
+`no-installman'
+ The generated `Makefile.in' will not cause man pages to be
+ installed by default. However, an `install-man' target will still
+ be available for optional installation. This option is disallowed
+ at `gnu' strictness and above.
+
+`nostdinc'
+ This option can be used to disable the standard `-I' options that
+ are ordinarily automatically provided by Automake.
+
+`no-texinfo.tex'
+ Don't require `texinfo.tex', even if there are texinfo files in
+ this directory.
+
+`parallel-tests'
+ Enable test suite harness for `TESTS' that can run tests in
+ parallel (*note Parallel Test Harness::, for more information).
+
+`serial-tests'
+ Enable the older serial test suite harness for `TESTS' (*note
+ Serial Test Harness::, for more information). This is still the
+ default for the moment.
+
+`readme-alpha'
+ If this release is an alpha release, and the file `README-alpha'
+ exists, then it will be added to the distribution. If this option
+ is given, version numbers are expected to follow one of two forms.
+ The first form is `MAJOR.MINOR.ALPHA', where each element is a
+ number; the final period and number should be left off for
+ non-alpha releases. The second form is `MAJOR.MINORALPHA', where
+ ALPHA is a letter; it should be omitted for non-alpha releases.
+
+`silent-rules'
+ Enable less verbose build rules. This can be used to let build
+ rules output status lines of the form:
+ GEN OUTPUT-FILE
+ CC OBJECT-FILE
+ instead of printing the command that will be executed to update
+ OUTPUT-FILE or to compile OBJECT-FILE. It can also silence
+ `libtool' output.
+
+ For more information about how to use, enable, or disable silent
+ rules, *note Automake silent-rules Option::.
+
+`std-options'
+ Make the `installcheck' rule check that installed scripts and
+ programs support the `--help' and `--version' options. This also
+ provides a basic check that the program's run-time dependencies
+ are satisfied after installation.
+
+ In a few situations, programs (or scripts) have to be exempted
+ from this test. For instance, `false' (from GNU coreutils) is
+ never successful, even for `--help' or `--version'. You can list
+ such programs in the variable `AM_INSTALLCHECK_STD_OPTIONS_EXEMPT'.
+ Programs (not scripts) listed in this variable should be suffixed
+ by `$(EXEEXT)' for the sake of Windows or OS/2. For instance,
+ suppose we build `false' as a program but `true.sh' as a script,
+ and that neither of them support `--help' or `--version':
+
+ AUTOMAKE_OPTIONS = std-options
+ bin_PROGRAMS = false ...
+ bin_SCRIPTS = true.sh ...
+ AM_INSTALLCHECK_STD_OPTIONS_EXEMPT = false$(EXEEXT) true.sh
+
+`subdir-objects'
+ If this option is specified, then objects are placed into the
+ subdirectory of the build directory corresponding to the
+ subdirectory of the source file. For instance, if the source file
+ is `subdir/file.cxx', then the output file would be
+ `subdir/file.o'.
+
+ In order to use this option with C sources, you should add
+ `AM_PROG_CC_C_O' to `configure.ac'.
+
+`tar-v7'
+`tar-ustar'
+`tar-pax'
+ These three mutually exclusive options select the tar format to use
+ when generating tarballs with `make dist'. (The tar file created
+ is then compressed according to the set of `no-dist-gzip',
+ `dist-bzip2', `dist-lzip', `dist-xz' and `dist-tarZ' options in
+ use.)
+
+ These options must be passed as arguments to `AM_INIT_AUTOMAKE'
+ (*note Macros::) because they can require additional configure
+ checks. Automake will complain if it sees such options in an
+ `AUTOMAKE_OPTIONS' variable.
+
+ `tar-v7' selects the old V7 tar format. This is the historical
+ default. This antiquated format is understood by all tar
+ implementations and supports file names with up to 99 characters.
+ When given longer file names some tar implementations will
+ diagnose the problem while other will generate broken tarballs or
+ use non-portable extensions. Furthermore, the V7 format cannot
+ store empty directories. When using this format, consider using
+ the `filename-length-max=99' option to catch file names too long.
+
+ `tar-ustar' selects the ustar format defined by POSIX 1003.1-1988.
+ This format is believed to be old enough to be portable. It fully
+ supports empty directories. It can store file names with up to
+ 256 characters, provided that the file name can be split at
+ directory separator in two parts, first of them being at most 155
+ bytes long. So, in most cases the maximum file name length will be
+ shorter than 256 characters. However you may run against broken
+ tar implementations that incorrectly handle file names longer than
+ 99 characters (please report them to <bug-automake@gnu.org> so we
+ can document this accurately).
+
+ `tar-pax' selects the new pax interchange format defined by POSIX
+ 1003.1-2001. It does not limit the length of file names. However,
+ this format is very young and should probably be restricted to
+ packages that target only very modern platforms. There are moves
+ to change the pax format in an upward-compatible way, so this
+ option may refer to a more recent version in the future.
+
+ *Note Controlling the Archive Format: (tar)Formats, for further
+ discussion about tar formats.
+
+ `configure' knows several ways to construct these formats. It
+ will not abort if it cannot find a tool up to the task (so that the
+ package can still be built), but `make dist' will fail.
+
+VERSION
+ A version number (e.g., `0.30') can be specified. If Automake is
+ not newer than the version specified, creation of the `Makefile.in'
+ will be suppressed.
+
+`-WCATEGORY' or `--warnings=CATEGORY'
+ These options behave exactly like their command-line counterpart
+ (*note automake Invocation::). This allows you to enable or
+ disable some warning categories on a per-file basis. You can also
+ setup some warnings for your entire project; for instance, try
+ `AM_INIT_AUTOMAKE([-Wall])' in your `configure.ac'.
+
+
+ Unrecognized options are diagnosed by `automake'.
+
+ If you want an option to apply to all the files in the tree, you can
+use the `AM_INIT_AUTOMAKE' macro in `configure.ac'. *Note Macros::.

+18 Miscellaneous Rules
+**********************
+
+There are a few rules and variables that didn't fit anywhere else.
+
+* Menu:
+
+* Tags:: Interfacing to cscope, etags and mkid
+* Suffixes:: Handling new file extensions
+
+\1f
+File: automake.info, Node: Tags, Next: Suffixes, Up: Miscellaneous
+
+18.1 Interfacing to `etags'
+===========================
+
+Automake will generate rules to generate `TAGS' files for use with GNU
+Emacs under some circumstances.
+
+ If any C, C++ or Fortran 77 source code or headers are present, then
+`tags' and `TAGS' rules will be generated for the directory. All files
+listed using the `_SOURCES', `_HEADERS', and `_LISP' primaries will be
+used to generate tags. Note that generated source files that are not
+distributed must be declared in variables like `nodist_noinst_HEADERS'
+or `nodist_PROG_SOURCES' or they will be ignored.
+
+ A `tags' rule will be output at the topmost directory of a
+multi-directory package. When run from this topmost directory, `make
+tags' will generate a `TAGS' file that includes by reference all `TAGS'
+files from subdirectories.
+
+ The `tags' rule will also be generated if the variable `ETAGS_ARGS'
+is defined. This variable is intended for use in directories that
+contain taggable source that `etags' does not understand. The user can
+use the `ETAGSFLAGS' to pass additional flags to `etags';
+`AM_ETAGSFLAGS' is also available for use in `Makefile.am'.
+
+ Here is how Automake generates tags for its source, and for nodes in
+its Texinfo file:
+
+ ETAGS_ARGS = automake.in --lang=none \
+ --regex='/^@node[ \t]+\([^,]+\)/\1/' automake.texi
+
+ If you add file names to `ETAGS_ARGS', you will probably also want
+to define `TAGS_DEPENDENCIES'. The contents of this variable are added
+directly to the dependencies for the `tags' rule.
+
+ Automake also generates a `ctags' rule that can be used to build
+`vi'-style `tags' files. The variable `CTAGS' is the name of the
+program to invoke (by default `ctags'); `CTAGSFLAGS' can be used by the
+user to pass additional flags, and `AM_CTAGSFLAGS' can be used by the
+`Makefile.am'.
+
+ Automake will also generate an `ID' rule that will run `mkid' on the
+source. This is only supported on a directory-by-directory basis.
+
+ Similarly, the `cscope' rule will create a list of all the source
+files in the tree and run `cscope' to build an inverted index database.
+The variable `CSCOPE' is the name of the program to invoke (by default
+`cscope'); `CSCOPEFLAGS' and `CSCOPE_ARGS' can be used by the user to
+pass additional flags and file names respectively, while
+`AM_CSCOPEFLAGS' can be used by the `Makefile.am'. Note that,
+currently, the Automake-provided `cscope' support, when used in a VPATH
+build, might not work well with non-GNU make implementations
+(especially with make implementations performing *note VPATH rewrites:
+(autoconf)Automatic Rule Rewriting.).
+
+ Finally, Automake also emits rules to support the GNU Global Tags
+program (http://www.gnu.org/software/global/). The `GTAGS' rule runs
+Global Tags and puts the result in the top build directory. The
+variable `GTAGS_ARGS' holds arguments that are passed to `gtags'.
+

+File: automake.info, Node: Suffixes, Prev: Tags, Up: Miscellaneous
+
+18.2 Handling new file extensions
+=================================
+
+It is sometimes useful to introduce a new implicit rule to handle a file
+type that Automake does not know about.
+
+ For instance, suppose you had a compiler that could compile `.foo'
+files to `.o' files. You would simply define a suffix rule for your
+language:
+
+ .foo.o:
+ foocc -c -o $@ $<
+
+ Then you could directly use a `.foo' file in a `_SOURCES' variable
+and expect the correct results:
+
+ bin_PROGRAMS = doit
+ doit_SOURCES = doit.foo
+
+ This was the simpler and more common case. In other cases, you will
+have to help Automake to figure out which extensions you are defining
+your suffix rule for. This usually happens when your extension does not
+start with a dot. Then, all you have to do is to put a list of new
+suffixes in the `SUFFIXES' variable *before* you define your implicit
+rule.
+
+ For instance, the following definition prevents Automake from
+misinterpreting the `.idlC.cpp:' rule as an attempt to transform
+`.idlC' files into `.cpp' files.
+
+ SUFFIXES = .idl C.cpp
+ .idlC.cpp:
+ # whatever
+
+ As you may have noted, the `SUFFIXES' variable behaves like the
+`.SUFFIXES' special target of `make'. You should not touch `.SUFFIXES'
+yourself, but use `SUFFIXES' instead and let Automake generate the
+suffix list for `.SUFFIXES'. Any given `SUFFIXES' go at the start of
+the generated suffixes list, followed by Automake generated suffixes
+not already in the list.
+

+File: automake.info, Node: Include, Next: Conditionals, Prev: Miscellaneous, Up: Top
+
+19 Include
+**********
+
+Automake supports an `include' directive that can be used to include
+other `Makefile' fragments when `automake' is run. Note that these
+fragments are read and interpreted by `automake', not by `make'. As
+with conditionals, `make' has no idea that `include' is in use.
+
+ There are two forms of `include':
+
+`include $(srcdir)/file'
+ Include a fragment that is found relative to the current source
+ directory.
+
+`include $(top_srcdir)/file'
+ Include a fragment that is found relative to the top source
+ directory.
+
+ Note that if a fragment is included inside a conditional, then the
+condition applies to the entire contents of that fragment.
+
+ Makefile fragments included this way are always distributed because
+they are needed to rebuild `Makefile.in'.
+

+
+20 Conditionals
+***************
+
+Automake supports a simple type of conditionals.
+
+ These conditionals are not the same as conditionals in GNU Make.
+Automake conditionals are checked at configure time by the `configure'
+script, and affect the translation from `Makefile.in' to `Makefile'.
+They are based on options passed to `configure' and on results that
+`configure' has discovered about the host system. GNU Make
+conditionals are checked at `make' time, and are based on variables
+passed to the make program or defined in the `Makefile'.
+
+ Automake conditionals will work with any make program.

+\1f
+File: automake.info, Node: Usage of Conditionals, Next: Limits of Conditionals, Up: Conditionals
+
+20.1 Usage of Conditionals
+==========================
+
+Before using a conditional, you must define it by using
+`AM_CONDITIONAL' in the `configure.ac' file (*note Macros::).
+
+ -- Macro: AM_CONDITIONAL (CONDITIONAL, CONDITION)
+ The conditional name, CONDITIONAL, should be a simple string
+ starting with a letter and containing only letters, digits, and
+ underscores. It must be different from `TRUE' and `FALSE' that
+ are reserved by Automake.
+
+ The shell CONDITION (suitable for use in a shell `if' statement)
+ is evaluated when `configure' is run. Note that you must arrange
+ for _every_ `AM_CONDITIONAL' to be invoked every time `configure'
+ is run. If `AM_CONDITIONAL' is run conditionally (e.g., in a
+ shell `if' statement), then the result will confuse `automake'.
+
+ Conditionals typically depend upon options that the user provides to
+the `configure' script. Here is an example of how to write a
+conditional that is true if the user uses the `--enable-debug' option.
+
+ AC_ARG_ENABLE([debug],
+ [ --enable-debug Turn on debugging],
+ [case "${enableval}" in
+ yes) debug=true ;;
+ no) debug=false ;;
+ *) AC_MSG_ERROR([bad value ${enableval} for --enable-debug]) ;;
+ esac],[debug=false])
+ AM_CONDITIONAL([DEBUG], [test x$debug = xtrue])
+
+ Here is an example of how to use that conditional in `Makefile.am':
+
+ if DEBUG
+ DBG = debug
+ else
+ DBG =
+ endif
+ noinst_PROGRAMS = $(DBG)
+
+ This trivial example could also be handled using `EXTRA_PROGRAMS'
+(*note Conditional Programs::).
+
+ You may only test a single variable in an `if' statement, possibly
+negated using `!'. The `else' statement may be omitted. Conditionals
+may be nested to any depth. You may specify an argument to `else' in
+which case it must be the negation of the condition used for the
+current `if'. Similarly you may specify the condition that is closed
+on the `endif' line:
+
+ if DEBUG
+ DBG = debug
+ else !DEBUG
+ DBG =
+ endif !DEBUG
+
+Unbalanced conditions are errors. The `if', `else', and `endif'
+statements should not be indented, i.e., start on column one.
+
+ The `else' branch of the above two examples could be omitted, since
+assigning the empty string to an otherwise undefined variable makes no
+difference.
+
+ In order to allow access to the condition registered by
+`AM_CONDITIONAL' inside `configure.ac', and to allow conditional
+`AC_CONFIG_FILES', `AM_COND_IF' may be used:
+
+ -- Macro: AM_COND_IF (CONDITIONAL, [IF-TRUE], [IF-FALSE])
+ If CONDITIONAL is fulfilled, execute IF-TRUE, otherwise execute
+ IF-FALSE. If either branch contains `AC_CONFIG_FILES', it will
+ cause `automake' to output the rules for the respective files only
+ for the given condition.
+
+ `AM_COND_IF' macros may be nested when m4 quotation is used properly
+(*note M4 Quotation: (autoconf)M4 Quotation.).
+
+ Here is an example of how to define a conditional config file:
+
+ AM_CONDITIONAL([SHELL_WRAPPER], [test "x$with_wrapper" = xtrue])
+ AM_COND_IF([SHELL_WRAPPER],
+ [AC_CONFIG_FILES([wrapper:wrapper.in])])
+
+\1f
+File: automake.info, Node: Limits of Conditionals, Prev: Usage of Conditionals, Up: Conditionals
+
+20.2 Limits of Conditionals
+===========================
+
+Conditionals should enclose complete statements like variables or rules
+definitions. Automake cannot deal with conditionals used inside a
+variable definition, for instance, and is not even able to diagnose
+this situation. The following example would not work:
+
+ # This syntax is not understood by Automake
+ AM_CPPFLAGS = \
+ -DFEATURE_A \
+ if WANT_DEBUG
+ -DDEBUG \
+ endif
+ -DFEATURE_B
+
+ However the intended definition of `AM_CPPFLAGS' can be achieved with
+
+ if WANT_DEBUG
+ DEBUGFLAGS = -DDEBUG
+ endif
+ AM_CPPFLAGS = -DFEATURE_A $(DEBUGFLAGS) -DFEATURE_B
+
+or
+
+ AM_CPPFLAGS = -DFEATURE_A
+ if WANT_DEBUG
+ AM_CPPFLAGS += -DDEBUG
+ endif
+ AM_CPPFLAGS += -DFEATURE_B
+
+ More details and examples of conditionals are described alongside
+various Automake features in this manual (*note Conditional
+Subdirectories::, *note Conditional Sources::, *note Conditional
+Programs::, *note Conditional Libtool Libraries::, *note Conditional
+Libtool Sources::).

+
+21.1 Make is verbose by default
+===============================
+
+Normally, when executing the set of rules associated with a target,
+`make' prints each rule before it is executed. This behaviour, while
+having been in place for a long time, and being even mandated by the
+POSIX standard, starkly violates the "silence is golden" UNIX
+principle(1):
+
+ When a program has nothing interesting or surprising to say, it
+ should say nothing. Well-behaved Unix programs do their jobs
+ unobtrusively, with a minimum of fuss and bother. Silence is
+ golden.
+
+ In fact, while such verbosity of `make' can theoretically be useful
+to track bugs and understand reasons of failures right away, it can
+also hide warning and error messages from `make'-invoked tools,
+drowning them in a flood of uninteresting and seldom useful messages,
+and thus allowing them to go easily undetected.
+
+ This problem can be very annoying, especially for developers, who
+usually know quite well what's going on behind the scenes, and for whom
+the verbose output from `make' ends up being mostly noise that hampers
+the easy detection of potentially important warning messages.

+
+21.2 Standard and generic ways to silence make
+==============================================
+
+Here we describe some common idioms/tricks to obtain a quieter make
+output, with their relative advantages and drawbacks. In the next
+section (*note Automake silent-rules Option::) we'll see how Automake
+can help in this respect.
+
+ * `make -s'
+
+ This simply causes `make' not to print _any_ rule before executing
+ it.
+
+ The `-s' flag is mandated by POSIX, universally supported, and its
+ purpose and function are easy to understand.
+
+ But it also has its serious limitations too. First of all, it
+ embodies an "all or nothing" strategy, i.e., either everything is
+ silenced, or nothing is; this lack of granularity can sometimes be
+ a fatal flaw. Moreover, when the `-s' flag is used, the `make'
+ output might turn out to be too much terse; in case of errors, the
+ user won't be able to easily see what rule or command have caused
+ them, or even, in case of tools with poor error reporting, what
+ the errors were!
+
+ * `make >/dev/null || make'
+
+ Apparently, this perfectly obeys the "silence is golden" rule:
+ warnings from stderr are passed through, output reporting is done
+ only in case of error, and in that case it should provide a
+ verbose-enough report to allow an easy determination of the error
+ location and causes.
+
+ However, calling `make' two times in a row might hide errors
+ (especially intermittent ones), or subtly change the expected
+ semantic of the `make' calls -- things these which can clearly make
+ debugging and error assessment very difficult.
+
+ * `make --no-print-directory'
+
+ This is GNU `make' specific. When called with the
+ `--no-print-directory' option, GNU `make' will disable printing of
+ the working directory by invoked sub-`make's (the well-known
+ "Entering/Leaving directory ..." messages). This helps to
+ decrease the verbosity of the output, but experience has shown that
+ it can also often render debugging considerably harder in projects
+ using deeply-nested `make' recursion.
+
+ As an aside, notice that the `--no-print-directory' option is
+ automatically activated if the `-s' flag is used.

+
+21.3 How Automake can help in silencing make
+============================================
+
+The tricks and idioms for silencing `make' described in the previous
+section can be useful from time to time, but we've seen that they all
+have their serious drawbacks and limitations. That's why automake
+provides support for a more advanced and flexible way of obtaining
+quieter output from `make': the `silent-rules' mode.
+
+ To give the gist of what `silent-rules' can do, here is a simple
+comparison between a typical `make' output (where silent rules are
+disabled) and one with silent rules enabled:
+
+ % cat Makefile.am
+ bin_PROGRAMS = foo
+ foo_SOURCES = main.c func.c
+ % cat main.c
+ int main (void) { return func (); } /* func used undeclared */
+ % cat func.c
+ int func (void) { int i; return i; } /* i used uninitialized */
+
+ The make output is by default very verbose. This causes warnings
+ from the compiler to be somewhat hidden, and not immediate to spot.
+ % make CFLAGS=-Wall
+ gcc -DPACKAGE_NAME=\"foo\" -DPACKAGE_TARNAME=\"foo\" ...
+ -DPACKAGE_STRING=\"foo\ 1.0\" -DPACKAGE_BUGREPORT=\"\" ...
+ -DPACKAGE=\"foo\" -DVERSION=\"1.0\" -I. -Wall -MT main.o
+ -MD -MP -MF .deps/main.Tpo -c -o main.o main.c
+ main.c: In function ‘main’:
+ main.c:3:3: warning: implicit declaration of function ‘func’
+ mv -f .deps/main.Tpo .deps/main.Po
+ gcc -DPACKAGE_NAME=\"foo\" -DPACKAGE_TARNAME=\"foo\" ...
+ -DPACKAGE_STRING=\"foo\ 1.0\" -DPACKAGE_BUGREPORT=\"\" ...
+ -DPACKAGE=\"foo\" -DVERSION=\"1.0\" -I. -Wall -MT func.o
+ -MD -MP -MF .deps/func.Tpo -c -o func.o func.c
+ func.c: In function ‘func’:
+ func.c:4:3: warning: ‘i’ used uninitialized in this function
+ mv -f .deps/func.Tpo .deps/func.Po
+ gcc -Wall -o foo main.o func.o
+
+ Clean up, so that we we can rebuild everything from scratch.
+ % make clean
+ test -z "foo" || rm -f foo
+ rm -f *.o
+
+ Silent rules enabled: the output is minimal but informative. In
+ particular, the warnings from the compiler stick out very clearly.
+ % make V=0 CFLAGS=-Wall
+ CC main.o
+ main.c: In function ‘main’:
+ main.c:3:3: warning: implicit declaration of function ‘func’
+ CC func.o
+ func.c: In function ‘func’:
+ func.c:4:3: warning: ‘i’ used uninitialized in this function
+ CCLD foo
+
+ Also, in projects using `libtool', the use of silent rules can
+automatically enable the `libtool''s `--silent' option:
+
+ % cat Makefile.am
+ lib_LTLIBRARIES = libx.la
+
+ % make # Both make and libtool are verbose by default.
+ ...
+ libtool: compile: gcc -DPACKAGE_NAME=\"foo\" ... -DLT_OBJDIR=\".libs/\"
+ -I. -g -O2 -MT libx.lo -MD -MP -MF .deps/libx.Tpo -c libx.c -fPIC
+ -DPIC -o .libs/libx.o
+ mv -f .deps/libx.Tpo .deps/libx.Plo
+ /bin/sh ./libtool --tag=CC --mode=link gcc -g -O2 -o libx.la -rpath
+ /usr/local/lib libx.lo
+ libtool: link: gcc -shared .libs/libx.o -Wl,-soname -Wl,libx.so.0
+ -o .libs/libx.so.0.0.0
+ libtool: link: cd .libs && rm -f libx.so && ln -s libx.so.0.0.0 libx.so
+ ...
+
+ % make V=0
+ CC libx.lo
+ CCLD libx.la
+
+ Let's now see how the `silent-rules' mode interfaces with the
+package developer and the package user.
+
+ To enable the use of `silent-rules' in his package, a developer
+needs to do either of the following:
+
+ * Add the `silent-rules' option as argument to `AM_INIT_AUTOMAKE'.
+
+ * Call the `AM_SILENT_RULES' macro from within the `configure.ac'
+ file.
+
+ It is not possible to instead specify `silent-rules' in a
+`Makefile.am' file.
+
+ If the developer has done either of the above, then the user of the
+package may influence the verbosity at `configure' run time as well as
+at `make' run time:
+
+ * Passing `--enable-silent-rules' to `configure' will cause build
+ rules to be less verbose; the option `--disable-silent-rules' will
+ cause normal verbose output.
+
+ * At `make' run time, the default chosen at `configure' time may be
+ overridden: `make V=1' will produce verbose output, `make V=0'
+ less verbose output.
+
+ Note that silent rules are _disabled_ by default; the user must
+enable them explicitly at either `configure' run time or at `make' run
+time. We think that this is a good policy, since it provides the
+casual user with enough information to prepare a good bug report in
+case anything breaks.
+
+ Still, notwithstanding the rationales above, a developer who wants to
+make silent rules enabled by default in his own package can do so by
+adding a `yes' argument to the `AM_SILENT_RULES' call in
+`configure.ac'. We advise against this approach, though.
+
+ Users who prefer to have silent rules enabled by default can edit
+their `config.site' file to make the variable `enable_silent_rules'
+default to `yes'. This should still allow disabling silent rules at
+`configure' time and at `make' time.
+
+ For portability to different `make' implementations, package authors
+are advised to not set the variable `V' inside the `Makefile.am' file,
+to allow the user to override the value for subdirectories as well.
+
+ The current implementation of this feature normally uses nested
+variable expansion `$(VAR1$(V))', a `Makefile' feature that is not
+required by POSIX 2008 but is widely supported in practice. The
+`silent-rules' option thus turns off warnings about recursive variable
+expansion, which are in turn enabled by `-Wportability' (*note automake
+Invocation::). On the rare `make' implementations that do not support
+nested variable expansion, whether rules are silent is always
+determined at configure time, and cannot be overridden at make time.
+Future versions of POSIX are likely to require nested variable
+expansion, so this minor limitation should go away with time.
+
+ To extend the silent mode to your own rules, you have two choices:
+
+ * You can use the predefined variable `AM_V_GEN' as a prefix to
+ commands that should output a status line in silent mode, and
+ `AM_V_at' as a prefix to commands that should not output anything
+ in silent mode. When output is to be verbose, both of these
+ variables will expand to the empty string.
+
+ * You can add your own variables, so strings of your own choice are
+ shown. The following snippet shows how you would define your own
+ equivalent of `AM_V_GEN':
+
+ pkg_verbose = $(pkg_verbose_@AM_V@)
+ pkg_verbose_ = $(pkg_verbose_@AM_DEFAULT_V@)
+ pkg_verbose_0 = @echo PKG-GEN $@;
+
+ foo: foo.in
+ $(pkg_verbose)cp $(srcdir)/foo.in $@
+
+
+ As a final note, observe that, even when silent rules are enabled,
+the `--no-print-directory' option is still required with GNU `make' if
+the "Entering/Leaving directory ..." messages are to be disabled.

+
+22 The effect of `--gnu' and `--gnits'
+**************************************
+
+The `--gnu' option (or `gnu' in the `AUTOMAKE_OPTIONS' variable) causes
+`automake' to check the following:
+
+ * The files `INSTALL', `NEWS', `README', `AUTHORS', and `ChangeLog',
+ plus one of `COPYING.LIB', `COPYING.LESSER' or `COPYING', are
+ required at the topmost directory of the package.
+
+ If the `--add-missing' option is given, `automake' will add a
+ generic version of the `INSTALL' file as well as the `COPYING'
+ file containing the text of the current version of the GNU General
+ Public License existing at the time of this Automake release
+ (version 3 as this is written,
+ `http://www.gnu.org/copyleft/gpl.html'). However, an existing
+ `COPYING' file will never be overwritten by `automake'.
+
+ * The options `no-installman' and `no-installinfo' are prohibited.
+
+ Note that this option will be extended in the future to do even more
+checking; it is advisable to be familiar with the precise requirements
+of the GNU standards. Also, `--gnu' can require certain non-standard
+GNU programs to exist for use by various maintainer-only rules; for
+instance, in the future `pathchk' might be required for `make dist'.
+
+ The `--gnits' option does everything that `--gnu' does, and checks
+the following as well:
+
+ * `make installcheck' will check to make sure that the `--help' and
+ `--version' really print a usage message and a version string,
+ respectively. This is the `std-options' option (*note Options::).
+
+ * `make dist' will check to make sure the `NEWS' file has been
+ updated to the current version.
+
+ * `VERSION' is checked to make sure its format complies with Gnits
+ standards.
+
+ * If `VERSION' indicates that this is an alpha release, and the file
+ `README-alpha' appears in the topmost directory of a package, then
+ it is included in the distribution. This is done in `--gnits'
+ mode, and no other, because this mode is the only one where version
+ number formats are constrained, and hence the only mode where
+ Automake can automatically determine whether `README-alpha' should
+ be included.
+
+ * The file `THANKS' is required.

+
+23 The effect of `--cygnus'
+***************************
+
+_The features described in this section are deprecated; you must not
+use any of them in new code, and should remove their use from older but
+still maintained code: they will be withdrawn the next major Automake
+release (1.13)._
+
+ Some packages, notably GNU GCC and GNU gdb, used to have a build
+environment originally written at Cygnus Support (subsequently renamed
+Cygnus Solutions, and then later purchased by Red Hat). Packages with
+this ancestry are sometimes referred to as "Cygnus" trees.
+
+ A Cygnus tree has slightly different rules for how a `Makefile.in'
+is to be constructed. Passing `--cygnus' to `automake' will cause any
+generated `Makefile.in' to comply with Cygnus rules.
+
+ Here are the precise effects of `--cygnus':
+
+ * The `foreign' strictness is implied.
+
+ * The options `no-installinfo', `no-dependencies' and `no-dist' are
+ implied (*note Options::).
+
+ * The macro `AM_MAINTAINER_MODE' is required.
+
+ * Info files are always created in the build directory, and not in
+ the source directory. Packages that don't use the `cygnus' option
+ can emulate this effect by using the `no-installinfo' option and
+ listing the generated info files in the `CLEANFILES' variable.
+
+ * `texinfo.tex' is not required if a Texinfo source file is
+ specified. The assumption is that the file will be supplied, but
+ in a place that Automake cannot find - it is an artifact of how
+ Cygnus packages are typically bundled. This effect can be
+ emulated in packages not using the `cygnus' option with a proper
+ definition of the `TEXINFO_TEX' variable (*note Texinfo::).
+
+ * Certain tools will be searched for in the build tree as well as in
+ the user's `PATH'. These tools are `runtest', `expect',
+ `makeinfo' and `texi2dvi'.
+
+ * The `check' target doesn't depend on `all'.

+24 When Automake Isn't Enough
+*****************************
+
+In some situations, where Automake is not up to one task, one has to
+resort to handwritten rules or even handwritten `Makefile's.
+
+* Menu:
+
+* Extending:: Adding new rules or overriding existing ones.
+* Third-Party Makefiles:: Integrating Non-Automake `Makefile's.
+

+File: automake.info, Node: Extending, Next: Third-Party Makefiles, Up: Not Enough
+
+24.1 Extending Automake Rules
+=============================
+
+With some minor exceptions (for example `_PROGRAMS' variables, `TESTS',
+or `XFAIL_TESTS') being rewritten to append `$(EXEEXT)'), the contents
+of a `Makefile.am' is copied to `Makefile.in' verbatim.
+
+ These copying semantics mean that many problems can be worked around
+by simply adding some `make' variables and rules to `Makefile.am'.
+Automake will ignore these additions.
+
+ Since a `Makefile.in' is built from data gathered from three
+different places (`Makefile.am', `configure.ac', and `automake'
+itself), it is possible to have conflicting definitions of rules or
+variables. When building `Makefile.in' the following priorities are
+respected by `automake' to ensure the user always has the last word:
+
+ * User defined variables in `Makefile.am' have priority over
+ variables `AC_SUBST'ed from `configure.ac', and `AC_SUBST'ed
+ variables have priority over `automake'-defined variables.
+
+ * As far as rules are concerned, a user-defined rule overrides any
+ `automake'-defined rule for the same target.
+
+ These overriding semantics make it possible to fine tune some default
+settings of Automake, or replace some of its rules. Overriding
+Automake rules is often inadvisable, particularly in the topmost
+directory of a package with subdirectories. The `-Woverride' option
+(*note automake Invocation::) comes in handy to catch overridden
+definitions.
+
+ Note that Automake does not make any distinction between rules with
+commands and rules that only specify dependencies. So it is not
+possible to append new dependencies to an `automake'-defined target
+without redefining the entire rule.
+
+ However, various useful targets have a `-local' version you can
+specify in your `Makefile.am'. Automake will supplement the standard
+target with these user-supplied targets.
+
+ The targets that support a local version are `all', `info', `dvi',
+`ps', `pdf', `html', `check', `install-data', `install-dvi',
+`install-exec', `install-html', `install-info', `install-pdf',
+`install-ps', `uninstall', `installdirs', `installcheck' and the
+various `clean' targets (`mostlyclean', `clean', `distclean', and
+`maintainer-clean').
+
+ Note that there are no `uninstall-exec-local' or
+`uninstall-data-local' targets; just use `uninstall-local'. It doesn't
+make sense to uninstall just data or just executables.
+
+ For instance, here is one way to erase a subdirectory during `make
+clean' (*note Clean::).
+
+ clean-local:
+ -rm -rf testSubDir
+
+ You may be tempted to use `install-data-local' to install a file to
+some hard-coded location, but you should avoid this (*note Hard-Coded
+Install Paths::).
+
+ With the `-local' targets, there is no particular guarantee of
+execution order; typically, they are run early, but with parallel make,
+there is no way to be sure of that.
+
+ In contrast, some rules also have a way to run another rule, called a
+"hook"; hooks are always executed after the main rule's work is done.
+The hook is named after the principal target, with `-hook' appended.
+The targets allowing hooks are `install-data', `install-exec',
+`uninstall', `dist', and `distcheck'.
+
+ For instance, here is how to create a hard link to an installed
+program:
+
+ install-exec-hook:
+ ln $(DESTDIR)$(bindir)/program$(EXEEXT) \
+ $(DESTDIR)$(bindir)/proglink$(EXEEXT)
+
+ Although cheaper and more portable than symbolic links, hard links
+will not work everywhere (for instance, OS/2 does not have `ln').
+Ideally you should fall back to `cp -p' when `ln' does not work. An
+easy way, if symbolic links are acceptable to you, is to add
+`AC_PROG_LN_S' to `configure.ac' (*note Particular Program Checks:
+(autoconf)Particular Programs.) and use `$(LN_S)' in `Makefile.am'.
+
+ For instance, here is how you could install a versioned copy of a
+program using `$(LN_S)':
+
+ install-exec-hook:
+ cd $(DESTDIR)$(bindir) && \
+ mv -f prog$(EXEEXT) prog-$(VERSION)$(EXEEXT) && \
+ $(LN_S) prog-$(VERSION)$(EXEEXT) prog$(EXEEXT)
+
+ Note that we rename the program so that a new version will erase the
+symbolic link, not the real binary. Also we `cd' into the destination
+directory in order to create relative links.
+
+ When writing `install-exec-hook' or `install-data-hook', please bear
+in mind that the exec/data distinction is based on the installation
+directory, not on the primary used (*note The Two Parts of Install::).
+So a `foo_SCRIPTS' will be installed by `install-data', and a
+`barexec_SCRIPTS' will be installed by `install-exec'. You should
+define your hooks consequently.

+
+24.2 Third-Party `Makefile's
+============================
+
+In most projects all `Makefile's are generated by Automake. In some
+cases, however, projects need to embed subdirectories with handwritten
+`Makefile's. For instance, one subdirectory could be a third-party
+project with its own build system, not using Automake.
+
+ It is possible to list arbitrary directories in `SUBDIRS' or
+`DIST_SUBDIRS' provided each of these directories has a `Makefile' that
+recognizes all the following recursive targets.
+
+ When a user runs one of these targets, that target is run recursively
+in all subdirectories. This is why it is important that even
+third-party `Makefile's support them.
+
+`all'
+ Compile the entire package. This is the default target in
+ Automake-generated `Makefile's, but it does not need to be the
+ default in third-party `Makefile's.
+
+`distdir'
+ Copy files to distribute into `$(distdir)', before a tarball is
+ constructed. Of course this target is not required if the
+ `no-dist' option (*note Options::) is used.
+
+ The variables `$(top_distdir)' and `$(distdir)' (*note The dist
+ Hook::) will be passed from the outer package to the subpackage
+ when the `distdir' target is invoked. These two variables have
+ been adjusted for the directory that is being recursed into, so
+ they are ready to use.
+
+`install'
+`install-data'
+`install-exec'
+`uninstall'
+ Install or uninstall files (*note Install::).
+
+`install-dvi'
+`install-html'
+`install-info'
+`install-ps'
+`install-pdf'
+ Install only some specific documentation format (*note Texinfo::).
+
+`installdirs'
+ Create install directories, but do not install any files.
+
+`check'
+`installcheck'
+ Check the package (*note Tests::).
+
+`mostlyclean'
+`clean'
+`distclean'
+`maintainer-clean'
+ Cleaning rules (*note Clean::).
+
+`dvi'
+`pdf'
+`ps'
+`info'
+`html'
+ Build the documentation in various formats (*note Texinfo::).
+
+`tags'
+`ctags'
+ Build `TAGS' and `CTAGS' (*note Tags::).
+
+ If you have ever used Gettext in a project, this is a good example of
+how third-party `Makefile's can be used with Automake. The `Makefile's
+`gettextize' puts in the `po/' and `intl/' directories are handwritten
+`Makefile's that implement all these targets. That way they can be
+added to `SUBDIRS' in Automake packages.
+
+ Directories that are only listed in `DIST_SUBDIRS' but not in
+`SUBDIRS' need only the `distclean', `maintainer-clean', and `distdir'
+rules (*note Conditional Subdirectories::).
+
+ Usually, many of these rules are irrelevant to the third-party
+subproject, but they are required for the whole package to work. It's
+OK to have a rule that does nothing, so if you are integrating a
+third-party project with no documentation or tag support, you could
+simply augment its `Makefile' as follows:
+
+ EMPTY_AUTOMAKE_TARGETS = dvi pdf ps info html tags ctags
+ .PHONY: $(EMPTY_AUTOMAKE_TARGETS)
+ $(EMPTY_AUTOMAKE_TARGETS):
+
+ Another aspect of integrating third-party build systems is whether
+they support VPATH builds (*note VPATH Builds::). Obviously if the
+subpackage does not support VPATH builds the whole package will not
+support VPATH builds. This in turns means that `make distcheck' will
+not work, because it relies on VPATH builds. Some people can live
+without this (actually, many Automake users have never heard of `make
+distcheck'). Other people may prefer to revamp the existing
+`Makefile's to support VPATH. Doing so does not necessarily require
+Automake, only Autoconf is needed (*note Build Directories:
+(autoconf)Build Directories.). The necessary substitutions:
+`@srcdir@', `@top_srcdir@', and `@top_builddir@' are defined by
+`configure' when it processes a `Makefile' (*note Preset Output
+Variables: (autoconf)Preset Output Variables.), they are not computed
+by the Makefile like the aforementioned `$(distdir)' and
+`$(top_distdir)' variables.
+
+ It is sometimes inconvenient to modify a third-party `Makefile' to
+introduce the above required targets. For instance, one may want to
+keep the third-party sources untouched to ease upgrades to new versions.
+
+ Here are two other ideas. If GNU make is assumed, one possibility is
+to add to that subdirectory a `GNUmakefile' that defines the required
+targets and includes the third-party `Makefile'. For this to work in
+VPATH builds, `GNUmakefile' must lie in the build directory; the
+easiest way to do this is to write a `GNUmakefile.in' instead, and have
+it processed with `AC_CONFIG_FILES' from the outer package. For
+example if we assume `Makefile' defines all targets except the
+documentation targets, and that the `check' target is actually called
+`test', we could write `GNUmakefile' (or `GNUmakefile.in') like this:
+
+ # First, include the real Makefile
+ include Makefile
+ # Then, define the other targets needed by Automake Makefiles.
+ .PHONY: dvi pdf ps info html check
+ dvi pdf ps info html:
+ check: test
+
+ A similar idea that does not use `include' is to write a proxy
+`Makefile' that dispatches rules to the real `Makefile', either with
+`$(MAKE) -f Makefile.real $(AM_MAKEFLAGS) target' (if it's OK to rename
+the original `Makefile') or with `cd subdir && $(MAKE) $(AM_MAKEFLAGS)
+target' (if it's OK to store the subdirectory project one directory
+deeper). The good news is that this proxy `Makefile' can be generated
+with Automake. All we need are `-local' targets (*note Extending::)
+that perform the dispatch. Of course the other Automake features are
+available, so you could decide to let Automake perform distribution or
+installation. Here is a possible `Makefile.am':
+
+ all-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) all
+ check-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) test
+ clean-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) clean
+
+ # Assuming the package knows how to install itself
+ install-data-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) install-data
+ install-exec-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) install-exec
+ uninstall-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) uninstall
+
+ # Distribute files from here.
+ EXTRA_DIST = subdir/Makefile subdir/program.c ...
+
+ Pushing this idea to the extreme, it is also possible to ignore the
+subproject build system and build everything from this proxy
+`Makefile.am'. This might sound very sensible if you need VPATH builds
+but the subproject does not support them.

+25 Distributing `Makefile.in's
+******************************
+
+Automake places no restrictions on the distribution of the resulting
+`Makefile.in's. We still encourage software authors to distribute
+their work under terms like those of the GPL, but doing so is not
+required to use Automake.
+
+ Some of the files that can be automatically installed via the
+`--add-missing' switch do fall under the GPL. However, these also have
+a special exception allowing you to distribute them with your package,
+regardless of the licensing you choose.
+

+
+26 Automake API Versioning
+**************************
+
+New Automake releases usually include bug fixes and new features.
+Unfortunately they may also introduce new bugs and incompatibilities.
+This makes four reasons why a package may require a particular Automake
+version.
+
+ Things get worse when maintaining a large tree of packages, each one
+requiring a different version of Automake. In the past, this meant that
+any developer (and sometimes users) had to install several versions of
+Automake in different places, and switch `$PATH' appropriately for each
+package.
+
+ Starting with version 1.6, Automake installs versioned binaries.
+This means you can install several versions of Automake in the same
+`$prefix', and can select an arbitrary Automake version by running
+`automake-1.6' or `automake-1.7' without juggling with `$PATH'.
+Furthermore, `Makefile''s generated by Automake 1.6 will use
+`automake-1.6' explicitly in their rebuild rules.
+
+ The number `1.6' in `automake-1.6' is Automake's API version, not
+Automake's version. If a bug fix release is made, for instance
+Automake 1.6.1, the API version will remain 1.6. This means that a
+package that works with Automake 1.6 should also work with 1.6.1; after
+all, this is what people expect from bug fix releases.
+
+ If your package relies on a feature or a bug fix introduced in a
+release, you can pass this version as an option to Automake to ensure
+older releases will not be used. For instance, use this in your
+`configure.ac':
+
+ AM_INIT_AUTOMAKE([1.6.1]) dnl Require Automake 1.6.1 or better.
+
+or, in a particular `Makefile.am':
+
+ AUTOMAKE_OPTIONS = 1.6.1 # Require Automake 1.6.1 or better.
+
+Automake will print an error message if its version is older than the
+requested version.
+
+What is in the API
+==================
+
+Automake's programming interface is not easy to define. Basically it
+should include at least all *documented* variables and targets that a
+`Makefile.am' author can use, any behavior associated with them (e.g.,
+the places where `-hook''s are run), the command line interface of
+`automake' and `aclocal', ...
+
+What is not in the API
+======================
+
+Every undocumented variable, target, or command line option, is not part
+of the API. You should avoid using them, as they could change from one
+version to the other (even in bug fix releases, if this helps to fix a
+bug).
+
+ If it turns out you need to use such an undocumented feature, contact
+<automake@gnu.org> and try to get it documented and exercised by the
+test-suite.

+
+27 Upgrading a Package to a Newer Automake Version
+**************************************************
+
+Automake maintains three kind of files in a package.
+
+ * `aclocal.m4'
+
+ * `Makefile.in's
+
+ * auxiliary tools like `install-sh' or `py-compile'
+
+ `aclocal.m4' is generated by `aclocal' and contains some
+Automake-supplied M4 macros. Auxiliary tools are installed by
+`automake --add-missing' when needed. `Makefile.in's are built from
+`Makefile.am' by `automake', and rely on the definitions of the M4
+macros put in `aclocal.m4' as well as the behavior of the auxiliary
+tools installed.
+
+ Because all these files are closely related, it is important to
+regenerate all of them when upgrading to a newer Automake release. The
+usual way to do that is
+
+ aclocal # with any option needed (such a -I m4)
+ autoconf
+ automake --add-missing --force-missing
+
+or more conveniently:
+
+ autoreconf -vfi
+
+ The use of `--force-missing' ensures that auxiliary tools will be
+overridden by new versions (*note automake Invocation::).
+
+ It is important to regenerate all these files each time Automake is
+upgraded, even between bug fixes releases. For instance, it is not
+unusual for a bug fix to involve changes to both the rules generated in
+`Makefile.in' and the supporting M4 macros copied to `aclocal.m4'.
+
+ Presently `automake' is able to diagnose situations where
+`aclocal.m4' has been generated with another version of `aclocal'.
+However it never checks whether auxiliary scripts are up-to-date. In
+other words, `automake' will tell you when `aclocal' needs to be rerun,
+but it will never diagnose a missing `--force-missing'.
+
+ Before upgrading to a new major release, it is a good idea to read
+the file `NEWS'. This file lists all changes between releases: new
+features, obsolete constructs, known incompatibilities, and workarounds.

+
+28.1 CVS and generated files
+============================
+
+Background: distributed generated Files
+---------------------------------------
+
+Packages made with Autoconf and Automake ship with some generated files
+like `configure' or `Makefile.in'. These files were generated on the
+developer's host and are distributed so that end-users do not have to
+install the maintainer tools required to rebuild them. Other generated
+files like Lex scanners, Yacc parsers, or Info documentation, are
+usually distributed on similar grounds.
+
+ Automake outputs rules in `Makefile's to rebuild these files. For
+instance, `make' will run `autoconf' to rebuild `configure' whenever
+`configure.ac' is changed. This makes development safer by ensuring a
+`configure' is never out-of-date with respect to `configure.ac'.
+
+ As generated files shipped in packages are up-to-date, and because
+`tar' preserves times-tamps, these rebuild rules are not triggered when
+a user unpacks and builds a package.
+
+Background: CVS and Timestamps
+------------------------------
+
+Unless you use CVS keywords (in which case files must be updated at
+commit time), CVS preserves timestamp during `cvs commit' and `cvs
+import -d' operations.
+
+ When you check out a file using `cvs checkout' its timestamp is set
+to that of the revision that is being checked out.
+
+ However, during `cvs update', files will have the date of the
+update, not the original timestamp of this revision. This is meant to
+make sure that `make' notices sources files have been updated.
+
+ This timestamp shift is troublesome when both sources and generated
+files are kept under CVS. Because CVS processes files in lexical
+order, `configure.ac' will appear newer than `configure' after a `cvs
+update' that updates both files, even if `configure' was newer than
+`configure.ac' when it was checked in. Calling `make' will then
+trigger a spurious rebuild of `configure'.
+
+Living with CVS in Autoconfiscated Projects
+-------------------------------------------
+
+There are basically two clans amongst maintainers: those who keep all
+distributed files under CVS, including generated files, and those who
+keep generated files _out_ of CVS.
+
+All Files in CVS
+................
+
+ * The CVS repository contains all distributed files so you know
+ exactly what is distributed, and you can checkout any prior
+ version entirely.
+
+ * Maintainers can see how generated files evolve (for instance, you
+ can see what happens to your `Makefile.in's when you upgrade
+ Automake and make sure they look OK).
+
+ * Users do not need the autotools to build a checkout of the
+ project, it works just like a released tarball.
+
+ * If users use `cvs update' to update their copy, instead of `cvs
+ checkout' to fetch a fresh one, timestamps will be inaccurate.
+ Some rebuild rules will be triggered and attempt to run developer
+ tools such as `autoconf' or `automake'.
+
+ Actually, calls to such tools are all wrapped into a call to the
+ `missing' script discussed later (*note maintainer-mode::).
+ `missing' will take care of fixing the timestamps when these tools
+ are not installed, so that the build can continue.
+
+ * In distributed development, developers are likely to have different
+ version of the maintainer tools installed. In this case rebuilds
+ triggered by timestamp lossage will lead to spurious changes to
+ generated files. There are several solutions to this:
+
+ * All developers should use the same versions, so that the
+ rebuilt files are identical to files in CVS. (This starts to
+ be difficult when each project you work on uses different
+ versions.)
+
+ * Or people use a script to fix the timestamp after a checkout
+ (the GCC folks have such a script).
+
+ * Or `configure.ac' uses `AM_MAINTAINER_MODE', which will
+ disable all these rebuild rules by default. This is further
+ discussed in *note maintainer-mode::.
+
+ * Although we focused on spurious rebuilds, the converse can also
+ happen. CVS's timestamp handling can also let you think an
+ out-of-date file is up-to-date.
+
+ For instance, suppose a developer has modified `Makefile.am' and
+ has rebuilt `Makefile.in', and then decides to do a last-minute
+ change to `Makefile.am' right before checking in both files
+ (without rebuilding `Makefile.in' to account for the change).
+
+ This last change to `Makefile.am' makes the copy of `Makefile.in'
+ out-of-date. Since CVS processes files alphabetically, when
+ another developer `cvs update's his or her tree, `Makefile.in'
+ will happen to be newer than `Makefile.am'. This other developer
+ will not see that `Makefile.in' is out-of-date.
+
+
+Generated Files out of CVS
+..........................
+
+One way to get CVS and `make' working peacefully is to never store
+generated files in CVS, i.e., do not CVS-control files that are
+`Makefile' targets (also called _derived_ files).
+
+ This way developers are not annoyed by changes to generated files.
+It does not matter if they all have different versions (assuming they
+are compatible, of course). And finally, timestamps are not lost,
+changes to sources files can't be missed as in the
+`Makefile.am'/`Makefile.in' example discussed earlier.
+
+ The drawback is that the CVS repository is not an exact copy of what
+is distributed and that users now need to install various development
+tools (maybe even specific versions) before they can build a checkout.
+But, after all, CVS's job is versioning, not distribution.
+
+ Allowing developers to use different versions of their tools can also
+hide bugs during distributed development. Indeed, developers will be
+using (hence testing) their own generated files, instead of the
+generated files that will be released actually. The developer who
+prepares the tarball might be using a version of the tool that produces
+bogus output (for instance a non-portable C file), something other
+developers could have noticed if they weren't using their own versions
+of this tool.
+
+Third-party Files
+-----------------
+
+Another class of files not discussed here (because they do not cause
+timestamp issues) are files that are shipped with a package, but
+maintained elsewhere. For instance, tools like `gettextize' and
+`autopoint' (from Gettext) or `libtoolize' (from Libtool), will install
+or update files in your package.
+
+ These files, whether they are kept under CVS or not, raise similar
+concerns about version mismatch between developers' tools. The Gettext
+manual has a section about this, see *note CVS Issues: (gettext)CVS
+Issues.

+
+28.2 `missing' and `AM_MAINTAINER_MODE'
+=======================================
+
+`missing'
+---------
+
+The `missing' script is a wrapper around several maintainer tools,
+designed to warn users if a maintainer tool is required but missing.
+Typical maintainer tools are `autoconf', `automake', `bison', etc.
+Because file generated by these tools are shipped with the other
+sources of a package, these tools shouldn't be required during a user
+build and they are not checked for in `configure'.
+
+ However, if for some reason a rebuild rule is triggered and involves
+a missing tool, `missing' will notice it and warn the user. Besides
+the warning, when a tool is missing, `missing' will attempt to fix
+timestamps in a way that allows the build to continue. For instance,
+`missing' will touch `configure' if `autoconf' is not installed. When
+all distributed files are kept under version control, this feature of
+`missing' allows a user _with no maintainer tools_ to build a package
+off its version control repository, bypassing any timestamp
+inconsistency (implied by e.g. `cvs update' or `git clone').
+
+ If the required tool is installed, `missing' will run it and won't
+attempt to continue after failures. This is correct during
+development: developers love fixing failures. However, users with
+wrong versions of maintainer tools may get an error when the rebuild
+rule is spuriously triggered, halting the build. This failure to let
+the build continue is one of the arguments of the `AM_MAINTAINER_MODE'
+advocates.
+
+`AM_MAINTAINER_MODE'
+--------------------
+
+`AM_MAINTAINER_MODE' allows you to choose whether the so called
+"rebuild rules" should be enabled or disabled. With
+`AM_MAINTAINER_MODE([enable])', they are enabled by default, otherwise
+they are disabled by default. In the latter case, if you have
+`AM_MAINTAINER_MODE' in `configure.ac', and run `./configure && make',
+then `make' will *never* attempt to rebuild `configure',
+`Makefile.in's, Lex or Yacc outputs, etc. I.e., this disables build
+rules for files that are usually distributed and that users should
+normally not have to update.
+
+ The user can override the default setting by passing either
+`--enable-maintainer-mode' or `--disable-maintainer-mode' to
+`configure'.
+
+ People use `AM_MAINTAINER_MODE' either because they do not want their
+users (or themselves) annoyed by timestamps lossage (*note CVS::), or
+because they simply can't stand the rebuild rules and prefer running
+maintainer tools explicitly.
+
+ `AM_MAINTAINER_MODE' also allows you to disable some custom build
+rules conditionally. Some developers use this feature to disable rules
+that need exotic tools that users may not have available.
+
+ Several years ago Franc,ois Pinard pointed out several arguments
+against this `AM_MAINTAINER_MODE' macro. Most of them relate to
+insecurity. By removing dependencies you get non-dependable builds:
+changes to sources files can have no effect on generated files and this
+can be very confusing when unnoticed. He adds that security shouldn't
+be reserved to maintainers (what `--enable-maintainer-mode' suggests),
+on the contrary. If one user has to modify a `Makefile.am', then
+either `Makefile.in' should be updated or a warning should be output
+(this is what Automake uses `missing' for) but the last thing you want
+is that nothing happens and the user doesn't notice it (this is what
+happens when rebuild rules are disabled by `AM_MAINTAINER_MODE').
+
+ Jim Meyering, the inventor of the `AM_MAINTAINER_MODE' macro was
+swayed by Franc,ois's arguments, and got rid of `AM_MAINTAINER_MODE' in
+all of his packages.
+
+ Still many people continue to use `AM_MAINTAINER_MODE', because it
+helps them working on projects where all files are kept under version
+control, and because `missing' isn't enough if you have the wrong
+version of the tools.

+
+28.3 Why doesn't Automake support wildcards?
+============================================
+
+Developers are lazy. They would often like to use wildcards in
+`Makefile.am's, so that they would not need to remember to update
+`Makefile.am's every time they add, delete, or rename a file.
+
+ There are several objections to this:
+ * When using CVS (or similar) developers need to remember they have
+ to run `cvs add' or `cvs rm' anyway. Updating `Makefile.am'
+ accordingly quickly becomes a reflex.
+
+ Conversely, if your application doesn't compile because you forgot
+ to add a file in `Makefile.am', it will help you remember to `cvs
+ add' it.
+
+ * Using wildcards makes it easy to distribute files by mistake. For
+ instance, some code a developer is experimenting with (a test case,
+ say) that should not be part of the distribution.
+
+ * Using wildcards it's easy to omit some files by mistake. For
+ instance, one developer creates a new file, uses it in many places,
+ but forgets to commit it. Another developer then checks out the
+ incomplete project and is able to run `make dist' successfully,
+ even though a file is missing. By listing files, `make dist'
+ _will_ complain.
+
+ * Wildcards are not portable to some non-GNU `make' implementations,
+ e.g., NetBSD `make' will not expand globs such as `*' in
+ prerequisites of a target.
+
+ * Finally, it's really hard to _forget_ to add a file to
+ `Makefile.am': files that are not listed in `Makefile.am' are not
+ compiled or installed, so you can't even test them.
+
+ Still, these are philosophical objections, and as such you may
+disagree, or find enough value in wildcards to dismiss all of them.
+Before you start writing a patch against Automake to teach it about
+wildcards, let's see the main technical issue: portability.
+
+ Although `$(wildcard ...)' works with GNU `make', it is not portable
+to other `make' implementations.
+
+ The only way Automake could support `$(wildcard ...)' is by
+expending `$(wildcard ...)' when `automake' is run. The resulting
+`Makefile.in's would be portable since they would list all files and
+not use `$(wildcard ...)'. However that means developers would need to
+remember to run `automake' each time they add, delete, or rename files.
+
+ Compared to editing `Makefile.am', this is a very small gain. Sure,
+it's easier and faster to type `automake; make' than to type `emacs
+Makefile.am; make'. But nobody bothered enough to write a patch to add
+support for this syntax. Some people use scripts to generate file
+lists in `Makefile.am' or in separate `Makefile' fragments.
+
+ Even if you don't care about portability, and are tempted to use
+`$(wildcard ...)' anyway because you target only GNU Make, you should
+know there are many places where Automake needs to know exactly which
+files should be processed. As Automake doesn't know how to expand
+`$(wildcard ...)', you cannot use it in these places. `$(wildcard
+...)' is a black box comparable to `AC_SUBST'ed variables as far
+Automake is concerned.
+
+ You can get warnings about `$(wildcard ...') constructs using the
+`-Wportability' flag.

+
+28.4 Limitations on File Names
+==============================
+
+Automake attempts to support all kinds of file names, even those that
+contain unusual characters or are unusually long. However, some
+limitations are imposed by the underlying operating system and tools.
+
+ Most operating systems prohibit the use of the null byte in file
+names, and reserve `/' as a directory separator. Also, they require
+that file names are properly encoded for the user's locale. Automake
+is subject to these limits.
+
+ Portable packages should limit themselves to POSIX file names.
+These can contain ASCII letters and digits, `_', `.', and `-'. File
+names consist of components separated by `/'. File name components
+cannot begin with `-'.
+
+ Portable POSIX file names cannot contain components that exceed a
+14-byte limit, but nowadays it's normally safe to assume the
+more-generous XOPEN limit of 255 bytes. POSIX limits file names to 255
+bytes (XOPEN allows 1023 bytes), but you may want to limit a source
+tarball to file names of 99 bytes to avoid interoperability problems
+with old versions of `tar'.
+
+ If you depart from these rules (e.g., by using non-ASCII characters
+in file names, or by using lengthy file names), your installers may
+have problems for reasons unrelated to Automake. However, if this does
+not concern you, you should know about the limitations imposed by
+Automake itself. These limitations are undesirable, but some of them
+seem to be inherent to underlying tools like Autoconf, Make, M4, and
+the shell. They fall into three categories: install directories, build
+directories, and file names.
+
+ The following characters:
+
+ newline " # $ ' `
+
+ should not appear in the names of install directories. For example,
+the operand of `configure''s `--prefix' option should not contain these
+characters.
+
+ Build directories suffer the same limitations as install directories,
+and in addition should not contain the following characters:
+
+ & @ \
+
+ For example, the full name of the directory containing the source
+files should not contain these characters.
+
+ Source and installation file names like `main.c' are limited even
+further: they should conform to the POSIX/XOPEN rules described above.
+In addition, if you plan to port to non-POSIX environments, you should
+avoid file names that differ only in case (e.g., `makefile' and
+`Makefile'). Nowadays it is no longer worth worrying about the 8.3
+limits of DOS file systems.

+
+28.5 Errors with distclean
+==========================
+
+This is a diagnostic you might encounter while running `make distcheck'.
+
+ As explained in *note Checking the Distribution::, `make distcheck'
+attempts to build and check your package for errors like this one.
+
+ `make distcheck' will perform a `VPATH' build of your package (*note
+VPATH Builds::), and then call `make distclean'. Files left in the
+build directory after `make distclean' has run are listed after this
+error.
+
+ This diagnostic really covers two kinds of errors:
+
+ * files that are forgotten by distclean;
+
+ * distributed files that are erroneously rebuilt.
+
+ The former left-over files are not distributed, so the fix is to mark
+them for cleaning (*note Clean::), this is obvious and doesn't deserve
+more explanations.
+
+ The latter bug is not always easy to understand and fix, so let's
+proceed with an example. Suppose our package contains a program for
+which we want to build a man page using `help2man'. GNU `help2man'
+produces simple manual pages from the `--help' and `--version' output
+of other commands (*note Overview: (help2man)Top.). Because we don't
+want to force our users to install `help2man', we decide to distribute
+the generated man page using the following setup.
+
+ # This Makefile.am is bogus.
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c
+ dist_man_MANS = foo.1
+
+ foo.1: foo$(EXEEXT)
+ help2man --output=foo.1 ./foo$(EXEEXT)
+
+ This will effectively distribute the man page. However, `make
+distcheck' will fail with:
+
+ ERROR: files left in build directory after distclean:
+ ./foo.1
+
+ Why was `foo.1' rebuilt? Because although distributed, `foo.1'
+depends on a non-distributed built file: `foo$(EXEEXT)'.
+`foo$(EXEEXT)' is built by the user, so it will always appear to be
+newer than the distributed `foo.1'.
+
+ `make distcheck' caught an inconsistency in our package. Our intent
+was to distribute `foo.1' so users do not need to install `help2man',
+however since this rule causes this file to be always rebuilt, users
+_do_ need `help2man'. Either we should ensure that `foo.1' is not
+rebuilt by users, or there is no point in distributing `foo.1'.
+
+ More generally, the rule is that distributed files should never
+depend on non-distributed built files. If you distribute something
+generated, distribute its sources.
+
+ One way to fix the above example, while still distributing `foo.1'
+is to not depend on `foo$(EXEEXT)'. For instance, assuming `foo
+--version' and `foo --help' do not change unless `foo.c' or
+`configure.ac' change, we could write the following `Makefile.am':
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c
+ dist_man_MANS = foo.1
+
+ foo.1: foo.c $(top_srcdir)/configure.ac
+ $(MAKE) $(AM_MAKEFLAGS) foo$(EXEEXT)
+ help2man --output=foo.1 ./foo$(EXEEXT)
+
+ This way, `foo.1' will not get rebuilt every time `foo$(EXEEXT)'
+changes. The `make' call makes sure `foo$(EXEEXT)' is up-to-date
+before `help2man'. Another way to ensure this would be to use separate
+directories for binaries and man pages, and set `SUBDIRS' so that
+binaries are built before man pages.
+
+ We could also decide not to distribute `foo.1'. In this case it's
+fine to have `foo.1' dependent upon `foo$(EXEEXT)', since both will
+have to be rebuilt. However it would be impossible to build the
+package in a cross-compilation, because building `foo.1' involves an
+_execution_ of `foo$(EXEEXT)'.
+
+ Another context where such errors are common is when distributed
+files are built by tools that are built by the package. The pattern is
+similar:
+
+ distributed-file: built-tools distributed-sources
+ build-command
+
+should be changed to
+
+ distributed-file: distributed-sources
+ $(MAKE) $(AM_MAKEFLAGS) built-tools
+ build-command
+
+or you could choose not to distribute `distributed-file', if
+cross-compilation does not matter.
+
+ The points made through these examples are worth a summary:
+
+ * Distributed files should never depend upon non-distributed built
+ files.
+
+ * Distributed files should be distributed with all their
+ dependencies.
+
+ * If a file is _intended_ to be rebuilt by users, then there is no
+ point in distributing it.
+
+ For desperate cases, it's always possible to disable this check by
+setting `distcleancheck_listfiles' as documented in *note Checking the
+Distribution::. Make sure you do understand the reason why `make
+distcheck' complains before you do this. `distcleancheck_listfiles' is
+a way to _hide_ errors, not to fix them. You can always do better.

+
+28.6 Flag Variables Ordering
+============================
+
+ What is the difference between `AM_CFLAGS', `CFLAGS', and
+ `mumble_CFLAGS'?
+
+ Why does `automake' output `CPPFLAGS' after
+ `AM_CPPFLAGS' on compile lines? Shouldn't it be the converse?
+
+ My `configure' adds some warning flags into `CXXFLAGS'. In
+ one `Makefile.am' I would like to append a new flag, however if I
+ put the flag into `AM_CXXFLAGS' it is prepended to the other
+ flags, not appended.
+
+Compile Flag Variables
+----------------------
+
+This section attempts to answer all the above questions. We will
+mostly discuss `CPPFLAGS' in our examples, but actually the answer
+holds for all the compile flags used in Automake: `CCASFLAGS',
+`CFLAGS', `CPPFLAGS', `CXXFLAGS', `FCFLAGS', `FFLAGS', `GCJFLAGS',
+`LDFLAGS', `LFLAGS', `LIBTOOLFLAGS', `OBJCFLAGS', `OBJCXXFLAGS',
+`RFLAGS', `UPCFLAGS', and `YFLAGS'.
+
+ `CPPFLAGS', `AM_CPPFLAGS', and `mumble_CPPFLAGS' are three variables
+that can be used to pass flags to the C preprocessor (actually these
+variables are also used for other languages like C++ or preprocessed
+Fortran). `CPPFLAGS' is the user variable (*note User Variables::),
+`AM_CPPFLAGS' is the Automake variable, and `mumble_CPPFLAGS' is the
+variable specific to the `mumble' target (we call this a per-target
+variable, *note Program and Library Variables::).
+
+ Automake always uses two of these variables when compiling C sources
+files. When compiling an object file for the `mumble' target, the
+first variable will be `mumble_CPPFLAGS' if it is defined, or
+`AM_CPPFLAGS' otherwise. The second variable is always `CPPFLAGS'.
+
+ In the following example,
+
+ bin_PROGRAMS = foo bar
+ foo_SOURCES = xyz.c
+ bar_SOURCES = main.c
+ foo_CPPFLAGS = -DFOO
+ AM_CPPFLAGS = -DBAZ
+
+`xyz.o' will be compiled with `$(foo_CPPFLAGS) $(CPPFLAGS)', (because
+`xyz.o' is part of the `foo' target), while `main.o' will be compiled
+with `$(AM_CPPFLAGS) $(CPPFLAGS)' (because there is no per-target
+variable for target `bar').
+
+ The difference between `mumble_CPPFLAGS' and `AM_CPPFLAGS' being
+clear enough, let's focus on `CPPFLAGS'. `CPPFLAGS' is a user
+variable, i.e., a variable that users are entitled to modify in order
+to compile the package. This variable, like many others, is documented
+at the end of the output of `configure --help'.
+
+ For instance, someone who needs to add `/home/my/usr/include' to the
+C compiler's search path would configure a package with
+
+ ./configure CPPFLAGS='-I /home/my/usr/include'
+
+and this flag would be propagated to the compile rules of all
+`Makefile's.
+
+ It is also not uncommon to override a user variable at `make'-time.
+Many installers do this with `prefix', but this can be useful with
+compiler flags too. For instance, if, while debugging a C++ project,
+you need to disable optimization in one specific object file, you can
+run something like
+
+ rm file.o
+ make CXXFLAGS=-O0 file.o
+ make
+
+ The reason `$(CPPFLAGS)' appears after `$(AM_CPPFLAGS)' or
+`$(mumble_CPPFLAGS)' in the compile command is that users should always
+have the last say. It probably makes more sense if you think about it
+while looking at the `CXXFLAGS=-O0' above, which should supersede any
+other switch from `AM_CXXFLAGS' or `mumble_CXXFLAGS' (and this of
+course replaces the previous value of `CXXFLAGS').
+
+ You should never redefine a user variable such as `CPPFLAGS' in
+`Makefile.am'. Use `automake -Woverride' to diagnose such mistakes.
+Even something like
+
+ CPPFLAGS = -DDATADIR=\"$(datadir)\" @CPPFLAGS@
+
+is erroneous. Although this preserves `configure''s value of
+`CPPFLAGS', the definition of `DATADIR' will disappear if a user
+attempts to override `CPPFLAGS' from the `make' command line.
+
+ AM_CPPFLAGS = -DDATADIR=\"$(datadir)\"
+
+is all that is needed here if no per-target flags are used.
+
+ You should not add options to these user variables within
+`configure' either, for the same reason. Occasionally you need to
+modify these variables to perform a test, but you should reset their
+values afterwards. In contrast, it is OK to modify the `AM_' variables
+within `configure' if you `AC_SUBST' them, but it is rather rare that
+you need to do this, unless you really want to change the default
+definitions of the `AM_' variables in all `Makefile's.
+
+ What we recommend is that you define extra flags in separate
+variables. For instance, you may write an Autoconf macro that computes
+a set of warning options for the C compiler, and `AC_SUBST' them in
+`WARNINGCFLAGS'; you may also have an Autoconf macro that determines
+which compiler and which linker flags should be used to link with
+library `libfoo', and `AC_SUBST' these in `LIBFOOCFLAGS' and
+`LIBFOOLDFLAGS'. Then, a `Makefile.am' could use these variables as
+follows:
+
+ AM_CFLAGS = $(WARNINGCFLAGS)
+ bin_PROGRAMS = prog1 prog2
+ prog1_SOURCES = ...
+ prog2_SOURCES = ...
+ prog2_CFLAGS = $(LIBFOOCFLAGS) $(AM_CFLAGS)
+ prog2_LDFLAGS = $(LIBFOOLDFLAGS)
+
+ In this example both programs will be compiled with the flags
+substituted into `$(WARNINGCFLAGS)', and `prog2' will additionally be
+compiled with the flags required to link with `libfoo'.
+
+ Note that listing `AM_CFLAGS' in a per-target `CFLAGS' variable is a
+common idiom to ensure that `AM_CFLAGS' applies to every target in a
+`Makefile.in'.
+
+ Using variables like this gives you full control over the ordering of
+the flags. For instance, if there is a flag in $(WARNINGCFLAGS) that
+you want to negate for a particular target, you can use something like
+`prog1_CFLAGS = $(AM_CFLAGS) -no-flag'. If all these flags had been
+forcefully appended to `CFLAGS', there would be no way to disable one
+flag. Yet another reason to leave user variables to users.
+
+ Finally, we have avoided naming the variable of the example
+`LIBFOO_LDFLAGS' (with an underscore) because that would cause Automake
+to think that this is actually a per-target variable (like
+`mumble_LDFLAGS') for some non-declared `LIBFOO' target.
+
+Other Variables
+---------------
+
+There are other variables in Automake that follow similar principles to
+allow user options. For instance, Texinfo rules (*note Texinfo::) use
+`MAKEINFOFLAGS' and `AM_MAKEINFOFLAGS'. Similarly, DejaGnu tests
+(*note DejaGnu Tests::) use `RUNTESTDEFAULTFLAGS' and
+`AM_RUNTESTDEFAULTFLAGS'. The tags and ctags rules (*note Tags::) use
+`ETAGSFLAGS', `AM_ETAGSFLAGS', `CTAGSFLAGS', and `AM_CTAGSFLAGS'. Java
+rules (*note Java::) use `JAVACFLAGS' and `AM_JAVACFLAGS'. None of
+these rules support per-target flags (yet).
+
+ To some extent, even `AM_MAKEFLAGS' (*note Subdirectories::) obeys
+this naming scheme. The slight difference is that `MAKEFLAGS' is
+passed to sub-`make's implicitly by `make' itself.
+
+ However you should not think that all variables ending with `FLAGS'
+follow this convention. For instance, `DISTCHECK_CONFIGURE_FLAGS'
+(*note Checking the Distribution::) and `ACLOCAL_AMFLAGS' (see *note
+Rebuilding:: and *note Local Macros::), are two variables that are only
+useful to the maintainer and have no user counterpart.
+
+ `ARFLAGS' (*note A Library::) is usually defined by Automake and has
+neither `AM_' nor per-target cousin.
+
+ Finally you should not think that the existence of a per-target
+variable implies the existence of an `AM_' variable or of a user
+variable. For instance, the `mumble_LDADD' per-target variable
+overrides the makefile-wide `LDADD' variable (which is not a user
+variable), and `mumble_LIBADD' exists only as a per-target variable.
+*Note Program and Library Variables::.

+
+28.7 Why are object files sometimes renamed?
+============================================
+
+This happens when per-target compilation flags are used. Object files
+need to be renamed just in case they would clash with object files
+compiled from the same sources, but with different flags. Consider the
+following example.
+
+ bin_PROGRAMS = true false
+ true_SOURCES = generic.c
+ true_CPPFLAGS = -DEXIT_CODE=0
+ false_SOURCES = generic.c
+ false_CPPFLAGS = -DEXIT_CODE=1
+
+Obviously the two programs are built from the same source, but it would
+be bad if they shared the same object, because `generic.o' cannot be
+built with both `-DEXIT_CODE=0' _and_ `-DEXIT_CODE=1'. Therefore
+`automake' outputs rules to build two different objects:
+`true-generic.o' and `false-generic.o'.
+
+ `automake' doesn't actually look whether source files are shared to
+decide if it must rename objects. It will just rename all objects of a
+target as soon as it sees per-target compilation flags used.
+
+ It's OK to share object files when per-target compilation flags are
+not used. For instance, `true' and `false' will both use `version.o'
+in the following example.
+
+ AM_CPPFLAGS = -DVERSION=1.0
+ bin_PROGRAMS = true false
+ true_SOURCES = true.c version.c
+ false_SOURCES = false.c version.c
+
+ Note that the renaming of objects is also affected by the
+`_SHORTNAME' variable (*note Program and Library Variables::).
+
+\1f
+File: automake.info, Node: Per-Object Flags, Next: Multiple Outputs, Prev: Renamed Objects, Up: FAQ
+
+28.8 Per-Object Flags Emulation
+===============================
+
+ One of my source files needs to be compiled with different flags. How
+ do I do?
+
+ Automake supports per-program and per-library compilation flags (see
+*note Program and Library Variables:: and *note Flag Variables
+Ordering::). With this you can define compilation flags that apply to
+all files compiled for a target. For instance, in
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = foo.c foo.h bar.c bar.h main.c
+ foo_CFLAGS = -some -flags
+
+`foo-foo.o', `foo-bar.o', and `foo-main.o' will all be compiled with
+`-some -flags'. (If you wonder about the names of these object files,
+see *note Renamed Objects::.) Note that `foo_CFLAGS' gives the flags
+to use when compiling all the C sources of the _program_ `foo', it has
+nothing to do with `foo.c' or `foo-foo.o' specifically.
+
+ What if `foo.c' needs to be compiled into `foo.o' using some
+specific flags, that none of the other files requires? Obviously
+per-program flags are not directly applicable here. Something like
+per-object flags are expected, i.e., flags that would be used only when
+creating `foo-foo.o'. Automake does not support that, however this is
+easy to simulate using a library that contains only that object, and
+compiling this library with per-library flags.
+
+ bin_PROGRAMS = foo
+ foo_SOURCES = bar.c bar.h main.c
+ foo_CFLAGS = -some -flags
+ foo_LDADD = libfoo.a
+ noinst_LIBRARIES = libfoo.a
+ libfoo_a_SOURCES = foo.c foo.h
+ libfoo_a_CFLAGS = -some -other -flags
+
+ Here `foo-bar.o' and `foo-main.o' will all be compiled with `-some
+-flags', while `libfoo_a-foo.o' will be compiled using `-some -other
+-flags'. Eventually, all three objects will be linked to form `foo'.
+
+ This trick can also be achieved using Libtool convenience libraries,
+for instance `noinst_LTLIBRARIES = libfoo.la' (*note Libtool
+Convenience Libraries::).
+
+ Another tempting idea to implement per-object flags is to override
+the compile rules `automake' would output for these files. Automake
+will not define a rule for a target you have defined, so you could
+think about defining the `foo-foo.o: foo.c' rule yourself. We
+recommend against this, because this is error prone. For instance, if
+you add such a rule to the first example, it will break the day you
+decide to remove `foo_CFLAGS' (because `foo.c' will then be compiled as
+`foo.o' instead of `foo-foo.o', *note Renamed Objects::). Also in
+order to support dependency tracking, the two `.o'/`.obj' extensions,
+and all the other flags variables involved in a compilation, you will
+end up modifying a copy of the rule previously output by `automake' for
+this file. If a new release of Automake generates a different rule,
+your copy will need to be updated by hand.
+

+File: automake.info, Node: Multiple Outputs, Next: Hard-Coded Install Paths, Prev: Per-Object Flags, Up: FAQ
+
+28.9 Handling Tools that Produce Many Outputs
+=============================================
+
+This section describes a `make' idiom that can be used when a tool
+produces multiple output files. It is not specific to Automake and can
+be used in ordinary `Makefile's.
+
+ Suppose we have a program called `foo' that will read one file
+called `data.foo' and produce two files named `data.c' and `data.h'.
+We want to write a `Makefile' rule that captures this one-to-two
+dependency.
+
+ The naive rule is incorrect:
+
+ # This is incorrect.
+ data.c data.h: data.foo
+ foo data.foo
+
+What the above rule really says is that `data.c' and `data.h' each
+depend on `data.foo', and can each be built by running `foo data.foo'.
+In other words it is equivalent to:
+
+ # We do not want this.
+ data.c: data.foo
+ foo data.foo
+ data.h: data.foo
+ foo data.foo
+
+which means that `foo' can be run twice. Usually it will not be run
+twice, because `make' implementations are smart enough to check for the
+existence of the second file after the first one has been built; they
+will therefore detect that it already exists. However there are a few
+situations where it can run twice anyway:
+
+ * The most worrying case is when running a parallel `make'. If
+ `data.c' and `data.h' are built in parallel, two `foo data.foo'
+ commands will run concurrently. This is harmful.
+
+ * Another case is when the dependency (here `data.foo') is (or
+ depends upon) a phony target.
+
+ A solution that works with parallel `make' but not with phony
+dependencies is the following:
+
+ data.c data.h: data.foo
+ foo data.foo
+ data.h: data.c
+
+The above rules are equivalent to
+
+ data.c: data.foo
+ foo data.foo
+ data.h: data.foo data.c
+ foo data.foo
+
+therefore a parallel `make' will have to serialize the builds of
+`data.c' and `data.h', and will detect that the second is no longer
+needed once the first is over.
+
+ Using this pattern is probably enough for most cases. However it
+does not scale easily to more output files (in this scheme all output
+files must be totally ordered by the dependency relation), so we will
+explore a more complicated solution.
+
+ Another idea is to write the following:
+
+ # There is still a problem with this one.
+ data.c: data.foo
+ foo data.foo
+ data.h: data.c
+
+The idea is that `foo data.foo' is run only when `data.c' needs to be
+updated, but we further state that `data.h' depends upon `data.c'.
+That way, if `data.h' is required and `data.foo' is out of date, the
+dependency on `data.c' will trigger the build.
+
+ This is almost perfect, but suppose we have built `data.h' and
+`data.c', and then we erase `data.h'. Then, running `make data.h' will
+not rebuild `data.h'. The above rules just state that `data.c' must be
+up-to-date with respect to `data.foo', and this is already the case.
+
+ What we need is a rule that forces a rebuild when `data.h' is
+missing. Here it is:
+
+ data.c: data.foo
+ foo data.foo
+ data.h: data.c
+ ## Recover from the removal of $@
+ @if test -f $@; then :; else \
+ rm -f data.c; \
+ $(MAKE) $(AM_MAKEFLAGS) data.c; \
+ fi
+
+ The above scheme can be extended to handle more outputs and more
+inputs. One of the outputs is selected to serve as a witness to the
+successful completion of the command, it depends upon all inputs, and
+all other outputs depend upon it. For instance, if `foo' should
+additionally read `data.bar' and also produce `data.w' and `data.x', we
+would write:
+
+ data.c: data.foo data.bar
+ foo data.foo data.bar
+ data.h data.w data.x: data.c
+ ## Recover from the removal of $@
+ @if test -f $@; then :; else \
+ rm -f data.c; \
+ $(MAKE) $(AM_MAKEFLAGS) data.c; \
+ fi
+
+ However there are now three minor problems in this setup. One is
+related to the timestamp ordering of `data.h', `data.w', `data.x', and
+`data.c'. Another one is a race condition if a parallel `make'
+attempts to run multiple instances of the recover block at once.
+Finally, the recursive rule breaks `make -n' when run with GNU `make'
+(as well as some other `make' implementations), as it may remove
+`data.h' even when it should not (*note How the `MAKE' Variable Works:
+(make)MAKE Variable.).
+
+ Let us deal with the first problem. `foo' outputs four files, but
+we do not know in which order these files are created. Suppose that
+`data.h' is created before `data.c'. Then we have a weird situation.
+The next time `make' is run, `data.h' will appear older than `data.c',
+the second rule will be triggered, a shell will be started to execute
+the `if...fi' command, but actually it will just execute the `then'
+branch, that is: nothing. In other words, because the witness we
+selected is not the first file created by `foo', `make' will start a
+shell to do nothing each time it is run.
+
+ A simple riposte is to fix the timestamps when this happens.
+
+ data.c: data.foo data.bar
+ foo data.foo data.bar
+ data.h data.w data.x: data.c
+ @if test -f $@; then \
+ touch $@; \
+ else \
+ ## Recover from the removal of $@
+ rm -f data.c; \
+ $(MAKE) $(AM_MAKEFLAGS) data.c; \
+ fi
+
+ Another solution is to use a different and dedicated file as witness,
+rather than using any of `foo''s outputs.
+
+ data.stamp: data.foo data.bar
+ @rm -f data.tmp
+ @touch data.tmp
+ foo data.foo data.bar
+ @mv -f data.tmp $@
+ data.c data.h data.w data.x: data.stamp
+ ## Recover from the removal of $@
+ @if test -f $@; then :; else \
+ rm -f data.stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) data.stamp; \
+ fi
+
+ `data.tmp' is created before `foo' is run, so it has a timestamp
+older than output files output by `foo'. It is then renamed to
+`data.stamp' after `foo' has run, because we do not want to update
+`data.stamp' if `foo' fails.
+
+ This solution still suffers from the second problem: the race
+condition in the recover rule. If, after a successful build, a user
+erases `data.c' and `data.h', and runs `make -j', then `make' may start
+both recover rules in parallel. If the two instances of the rule
+execute `$(MAKE) $(AM_MAKEFLAGS) data.stamp' concurrently the build is
+likely to fail (for instance, the two rules will create `data.tmp', but
+only one can rename it).
+
+ Admittedly, such a weird situation does not arise during ordinary
+builds. It occurs only when the build tree is mutilated. Here
+`data.c' and `data.h' have been explicitly removed without also
+removing `data.stamp' and the other output files. `make clean; make'
+will always recover from these situations even with parallel makes, so
+you may decide that the recover rule is solely to help non-parallel
+make users and leave things as-is. Fixing this requires some locking
+mechanism to ensure only one instance of the recover rule rebuilds
+`data.stamp'. One could imagine something along the following lines.
+
+ data.c data.h data.w data.x: data.stamp
+ ## Recover from the removal of $@
+ @if test -f $@; then :; else \
+ trap 'rm -rf data.lock data.stamp' 1 2 13 15; \
+ ## mkdir is a portable test-and-set
+ if mkdir data.lock 2>/dev/null; then \
+ ## This code is being executed by the first process.
+ rm -f data.stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) data.stamp; \
+ result=$$?; rm -rf data.lock; exit $$result; \
+ else \
+ ## This code is being executed by the follower processes.
+ ## Wait until the first process is done.
+ while test -d data.lock; do sleep 1; done; \
+ ## Succeed if and only if the first process succeeded.
+ test -f data.stamp; \
+ fi; \
+ fi
+
+ Using a dedicated witness, like `data.stamp', is very handy when the
+list of output files is not known beforehand. As an illustration,
+consider the following rules to compile many `*.el' files into `*.elc'
+files in a single command. It does not matter how `ELFILES' is defined
+(as long as it is not empty: empty targets are not accepted by POSIX).
+
+ ELFILES = one.el two.el three.el ...
+ ELCFILES = $(ELFILES:=c)
+
+ elc-stamp: $(ELFILES)
+ @rm -f elc-temp
+ @touch elc-temp
+ $(elisp_comp) $(ELFILES)
+ @mv -f elc-temp $@
+
+ $(ELCFILES): elc-stamp
+ @if test -f $@; then :; else \
+ ## Recover from the removal of $@
+ trap 'rm -rf elc-lock elc-stamp' 1 2 13 15; \
+ if mkdir elc-lock 2>/dev/null; then \
+ ## This code is being executed by the first process.
+ rm -f elc-stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) elc-stamp; \
+ rmdir elc-lock; \
+ else \
+ ## This code is being executed by the follower processes.
+ ## Wait until the first process is done.
+ while test -d elc-lock; do sleep 1; done; \
+ ## Succeed if and only if the first process succeeded.
+ test -f elc-stamp; exit $$?; \
+ fi; \
+ fi
+
+ These solutions all still suffer from the third problem, namely that
+they break the promise that `make -n' should not cause any actual
+changes to the tree. For those solutions that do not create lock files,
+it is possible to split the recover rules into two separate recipe
+commands, one of which does all work but the recursion, and the other
+invokes the recursive `$(MAKE)'. The solutions involving locking could
+act upon the contents of the `MAKEFLAGS' variable, but parsing that
+portably is not easy (*note The Make Macro MAKEFLAGS: (autoconf)The
+Make Macro MAKEFLAGS.). Here is an example:
+
+ ELFILES = one.el two.el three.el ...
+ ELCFILES = $(ELFILES:=c)
+
+ elc-stamp: $(ELFILES)
+ @rm -f elc-temp
+ @touch elc-temp
+ $(elisp_comp) $(ELFILES)
+ @mv -f elc-temp $@
+
+ $(ELCFILES): elc-stamp
+ ## Recover from the removal of $@
+ @dry=; for f in x $$MAKEFLAGS; do \
+ case $$f in \
+ *=*|--*);; \
+ *n*) dry=:;; \
+ esac; \
+ done; \
+ if test -f $@; then :; else \
+ $$dry trap 'rm -rf elc-lock elc-stamp' 1 2 13 15; \
+ if $$dry mkdir elc-lock 2>/dev/null; then \
+ ## This code is being executed by the first process.
+ $$dry rm -f elc-stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) elc-stamp; \
+ $$dry rmdir elc-lock; \
+ else \
+ ## This code is being executed by the follower processes.
+ ## Wait until the first process is done.
+ while test -d elc-lock && test -z "$$dry"; do \
+ sleep 1; \
+ done; \
+ ## Succeed if and only if the first process succeeded.
+ $$dry test -f elc-stamp; exit $$?; \
+ fi; \
+ fi
+
+ For completeness it should be noted that GNU `make' is able to
+express rules with multiple output files using pattern rules (*note
+Pattern Rule Examples: (make)Pattern Examples.). We do not discuss
+pattern rules here because they are not portable, but they can be
+convenient in packages that assume GNU `make'.

+
+28.10 Installing to Hard-Coded Locations
+========================================
+
+ My package needs to install some configuration file. I tried to use
+ the following rule, but `make distcheck' fails. Why?
+ # Do not do this.
+ install-data-local:
+ $(INSTALL_DATA) $(srcdir)/afile $(DESTDIR)/etc/afile
+
+ My package needs to populate the installation directory of another
+ package at install-time. I can easily compute that installation
+ directory in `configure', but if I install files therein,
+ `make distcheck' fails. How else should I do?
+
+ These two setups share their symptoms: `make distcheck' fails
+because they are installing files to hard-coded paths. In the later
+case the path is not really hard-coded in the package, but we can
+consider it to be hard-coded in the system (or in whichever tool that
+supplies the path). As long as the path does not use any of the
+standard directory variables (`$(prefix)', `$(bindir)', `$(datadir)',
+etc.), the effect will be the same: user-installations are impossible.
+
+ As a (non-root) user who wants to install a package, you usually
+have no right to install anything in `/usr' or `/usr/local'. So you do
+something like `./configure --prefix ~/usr' to install a package in
+your own `~/usr' tree.
+
+ If a package attempts to install something to some hard-coded path
+(e.g., `/etc/afile'), regardless of this `--prefix' setting, then the
+installation will fail. `make distcheck' performs such a `--prefix'
+installation, hence it will fail too.
+
+ Now, there are some easy solutions.
+
+ The above `install-data-local' example for installing `/etc/afile'
+would be better replaced by
+
+ sysconf_DATA = afile
+
+by default `sysconfdir' will be `$(prefix)/etc', because this is what
+the GNU Standards require. When such a package is installed on an FHS
+compliant system, the installer will have to set `--sysconfdir=/etc'.
+As the maintainer of the package you should not be concerned by such
+site policies: use the appropriate standard directory variable to
+install your files so that the installer can easily redefine these
+variables to match their site conventions.
+
+ Installing files that should be used by another package is slightly
+more involved. Let's take an example and assume you want to install a
+shared library that is a Python extension module. If you ask Python
+where to install the library, it will answer something like this:
+
+ % python -c 'from distutils import sysconfig;
+ print sysconfig.get_python_lib(1,0)'
+ /usr/lib/python2.5/site-packages
+
+ If you indeed use this absolute path to install your shared library,
+non-root users will not be able to install the package, hence distcheck
+fails.
+
+ Let's do better. The `sysconfig.get_python_lib()' function actually
+accepts a third argument that will replace Python's installation prefix.
+
+ % python -c 'from distutils import sysconfig;
+ print sysconfig.get_python_lib(1,0,"${exec_prefix}")'
+ ${exec_prefix}/lib/python2.5/site-packages
+
+ You can also use this new path. If you do
+ * root users can install your package with the same `--prefix' as
+ Python (you get the behavior of the previous attempt)
+
+ * non-root users can install your package too, they will have the
+ extension module in a place that is not searched by Python but they
+ can work around this using environment variables (and if you
+ installed scripts that use this shared library, it's easy to tell
+ Python were to look in the beginning of your script, so the script
+ works in both cases).
+
+ The `AM_PATH_PYTHON' macro uses similar commands to define
+`$(pythondir)' and `$(pyexecdir)' (*note Python::).
+
+ Of course not all tools are as advanced as Python regarding that
+substitution of PREFIX. So another strategy is to figure the part of
+the installation directory that must be preserved. For instance, here
+is how `AM_PATH_LISPDIR' (*note Emacs Lisp::) computes `$(lispdir)':
+
+ $EMACS -batch -q -eval '(while load-path
+ (princ (concat (car load-path) "\n"))
+ (setq load-path (cdr load-path)))' >conftest.out
+ lispdir=`sed -n
+ -e 's,/$,,'
+ -e '/.*\/lib\/x*emacs\/site-lisp$/{
+ s,.*/lib/\(x*emacs/site-lisp\)$,${libdir}/\1,;p;q;
+ }'
+ -e '/.*\/share\/x*emacs\/site-lisp$/{
+ s,.*/share/\(x*emacs/site-lisp\),${datarootdir}/\1,;p;q;
+ }'
+ conftest.out`
+
+ I.e., it just picks the first directory that looks like
+`*/lib/*emacs/site-lisp' or `*/share/*emacs/site-lisp' in the search
+path of emacs, and then substitutes `${libdir}' or `${datadir}'
+appropriately.
+
+ The emacs case looks complicated because it processes a list and
+expects two possible layouts, otherwise it's easy, and the benefits for
+non-root users are really worth the extra `sed' invocation.

+28.11 Debugging Make Rules
+==========================
+
+The rules and dependency trees generated by `automake' can get rather
+complex, and leave the developer head-scratching when things don't work
+as expected. Besides the debug options provided by the `make' command
+(*note Options Summary: (make)Options Summary.), here's a couple of
+further hints for debugging makefiles generated by `automake'
+effectively:
+
+ * If less verbose output has been enabled in the package with the
+ `silent-rules' option (*note Options::), you can use `make V=1' to
+ see the commands being executed.
+
+ * `make -n' can help show what would be done without actually doing
+ it. Note however, that this will _still execute_ commands prefixed
+ with `+', and, when using GNU `make', commands that contain the
+ strings `$(MAKE)' or `${MAKE}' (*note Instead of Execution:
+ (make)Instead of Execution.). Typically, this is helpful to show
+ what recursive rules would do, but it means that, in your own
+ rules, you should not mix such recursion with actions that change
+ any files.(1) Furthermore, note that GNU `make' will update
+ prerequisites for the `Makefile' file itself even with `-n' (*note
+ Remaking Makefiles: (make)Remaking Makefiles.).
+
+ * `make SHELL="/bin/bash -vx"' can help debug complex rules. *Note
+ The Make Macro SHELL: (autoconf)The Make Macro SHELL, for some
+ portability quirks associated with this construct.
+
+ * `echo 'print: ; @echo "$(VAR)"' | make -f Makefile -f - print' can
+ be handy to examine the expanded value of variables. You may need
+ to use a target other than `print' if that is already used or a
+ file with that name exists.
+
+ * `http://bashdb.sourceforge.net/remake/' provides a modified GNU
+ `make' command called `remake' that copes with complex GNU
+ `make'-specific Makefiles and allows to trace execution, examine
+ variables, and call rules interactively, much like a debugger.
+
+ ---------- Footnotes ----------
+
+ (1) Automake's `dist' and `distcheck' rules had a bug in this regard
+in that they created directories even with `-n', but this has been
+fixed in Automake 1.11.

+
+28.12 Reporting Bugs
+====================
+
+Most nontrivial software has bugs. Automake is no exception. Although
+we cannot promise we can or will fix a bug, and we might not even agree
+that it is a bug, we want to hear about problems you encounter. Often we
+agree they are bugs and want to fix them.
+
+ To make it possible for us to fix a bug, please report it. In order
+to do so effectively, it helps to know when and how to do it.
+
+ Before reporting a bug, it is a good idea to see if it is already
+known. You can look at the GNU Bug Tracker (http://debbugs.gnu.org/)
+and the bug-automake mailing list archives
+(http://lists.gnu.org/archive/html/bug-automake/) for previous bug
+reports. We previously used a Gnats database
+(http://sourceware.org/cgi-bin/gnatsweb.pl?database=automake) for bug
+tracking, so some bugs might have been reported there already. Please
+do not use it for new bug reports, however.
+
+ If the bug is not already known, it should be reported. It is very
+important to report bugs in a way that is useful and efficient. For
+this, please familiarize yourself with How to Report Bugs Effectively
+(http://www.chiark.greenend.org.uk/~sgtatham/bugs.html) and How to Ask
+Questions the Smart Way
+(http://catb.org/~esr/faqs/smart-questions.html). This helps you and
+developers to save time which can then be spent on fixing more bugs and
+implementing more features.
+
+ For a bug report, a feature request or other suggestions, please send
+email to <bug-automake@gnu.org>. This will then open a new bug in the
+bug tracker (http://debbugs.gnu.org/automake). Be sure to include the
+versions of Autoconf and Automake that you use. Ideally, post a
+minimal `Makefile.am' and `configure.ac' that reproduces the problem
+you encounter. If you have encountered test suite failures, please
+attach the `test-suite.log' file.

+
+ The purpose of this License is to make a manual, textbook, or other
+ functional and useful document "free" in the sense of freedom: to
+ assure everyone the effective freedom to copy and redistribute it,
+ with or without modifying it, either commercially or
+ noncommercially. Secondarily, this License preserves for the
+ author and publisher a way to get credit for their work, while not
+ being considered responsible for modifications made by others.
+
+ This License is a kind of "copyleft", which means that derivative
+ works of the document must themselves be free in the same sense.
+ It complements the GNU General Public License, which is a copyleft
+ license designed for free software.
+
+ We have designed this License in order to use it for manuals for
+ free software, because free software needs free documentation: a
+ free program should come with manuals providing the same freedoms
+ that the software does. But this License is not limited to
+ software manuals; it can be used for any textual work, regardless
+ of subject matter or whether it is published as a printed book.
+ We recommend this License principally for works whose purpose is
+ instruction or reference.
+
+ 1. APPLICABILITY AND DEFINITIONS
+
+ This License applies to any manual or other work, in any medium,
+ that contains a notice placed by the copyright holder saying it
+ can be distributed under the terms of this License. Such a notice
+ grants a world-wide, royalty-free license, unlimited in duration,
+ to use that work under the conditions stated herein. The
+ "Document", below, refers to any such manual or work. Any member
+ of the public is a licensee, and is addressed as "you". You
+ accept the license if you copy, modify or distribute the work in a
+ way requiring permission under copyright law.
+
+ A "Modified Version" of the Document means any work containing the
+ Document or a portion of it, either copied verbatim, or with
+ modifications and/or translated into another language.
+
+ A "Secondary Section" is a named appendix or a front-matter section
+ of the Document that deals exclusively with the relationship of the
+ publishers or authors of the Document to the Document's overall
+ subject (or to related matters) and contains nothing that could
+ fall directly within that overall subject. (Thus, if the Document
+ is in part a textbook of mathematics, a Secondary Section may not
+ explain any mathematics.) The relationship could be a matter of
+ historical connection with the subject or with related matters, or
+ of legal, commercial, philosophical, ethical or political position
+ regarding them.
+
+ The "Invariant Sections" are certain Secondary Sections whose
+ titles are designated, as being those of Invariant Sections, in
+ the notice that says that the Document is released under this
+ License. If a section does not fit the above definition of
+ Secondary then it is not allowed to be designated as Invariant.
+ The Document may contain zero Invariant Sections. If the Document
+ does not identify any Invariant Sections then there are none.
+
+ The "Cover Texts" are certain short passages of text that are
+ listed, as Front-Cover Texts or Back-Cover Texts, in the notice
+ that says that the Document is released under this License. A
+ Front-Cover Text may be at most 5 words, and a Back-Cover Text may
+ be at most 25 words.
+
+ A "Transparent" copy of the Document means a machine-readable copy,
+ represented in a format whose specification is available to the
+ general public, that is suitable for revising the document
+ straightforwardly with generic text editors or (for images
+ composed of pixels) generic paint programs or (for drawings) some
+ widely available drawing editor, and that is suitable for input to
+ text formatters or for automatic translation to a variety of
+ formats suitable for input to text formatters. A copy made in an
+ otherwise Transparent file format whose markup, or absence of
+ markup, has been arranged to thwart or discourage subsequent
+ modification by readers is not Transparent. An image format is
+ not Transparent if used for any substantial amount of text. A
+ copy that is not "Transparent" is called "Opaque".
+
+ Examples of suitable formats for Transparent copies include plain
+ ASCII without markup, Texinfo input format, LaTeX input format,
+ SGML or XML using a publicly available DTD, and
+ standard-conforming simple HTML, PostScript or PDF designed for
+ human modification. Examples of transparent image formats include
+ PNG, XCF and JPG. Opaque formats include proprietary formats that
+ can be read and edited only by proprietary word processors, SGML or
+ XML for which the DTD and/or processing tools are not generally
+ available, and the machine-generated HTML, PostScript or PDF
+ produced by some word processors for output purposes only.
+
+ The "Title Page" means, for a printed book, the title page itself,
+ plus such following pages as are needed to hold, legibly, the
+ material this License requires to appear in the title page. For
+ works in formats which do not have any title page as such, "Title
+ Page" means the text near the most prominent appearance of the
+ work's title, preceding the beginning of the body of the text.
+
+ The "publisher" means any person or entity that distributes copies
+ of the Document to the public.
+
+ A section "Entitled XYZ" means a named subunit of the Document
+ whose title either is precisely XYZ or contains XYZ in parentheses
+ following text that translates XYZ in another language. (Here XYZ
+ stands for a specific section name mentioned below, such as
+ "Acknowledgements", "Dedications", "Endorsements", or "History".)
+ To "Preserve the Title" of such a section when you modify the
+ Document means that it remains a section "Entitled XYZ" according
+ to this definition.
+
+ The Document may include Warranty Disclaimers next to the notice
+ which states that this License applies to the Document. These
+ Warranty Disclaimers are considered to be included by reference in
+ this License, but only as regards disclaiming warranties: any other
+ implication that these Warranty Disclaimers may have is void and
+ has no effect on the meaning of this License.
+
+ 2. VERBATIM COPYING
+
+ You may copy and distribute the Document in any medium, either
+ commercially or noncommercially, provided that this License, the
+ copyright notices, and the license notice saying this License
+ applies to the Document are reproduced in all copies, and that you
+ add no other conditions whatsoever to those of this License. You
+ may not use technical measures to obstruct or control the reading
+ or further copying of the copies you make or distribute. However,
+ you may accept compensation in exchange for copies. If you
+ distribute a large enough number of copies you must also follow
+ the conditions in section 3.
+
+ You may also lend copies, under the same conditions stated above,
+ and you may publicly display copies.
+
+ 3. COPYING IN QUANTITY
+
+ If you publish printed copies (or copies in media that commonly
+ have printed covers) of the Document, numbering more than 100, and
+ the Document's license notice requires Cover Texts, you must
+ enclose the copies in covers that carry, clearly and legibly, all
+ these Cover Texts: Front-Cover Texts on the front cover, and
+ Back-Cover Texts on the back cover. Both covers must also clearly
+ and legibly identify you as the publisher of these copies. The
+ front cover must present the full title with all words of the
+ title equally prominent and visible. You may add other material
+ on the covers in addition. Copying with changes limited to the
+ covers, as long as they preserve the title of the Document and
+ satisfy these conditions, can be treated as verbatim copying in
+ other respects.
+
+ If the required texts for either cover are too voluminous to fit
+ legibly, you should put the first ones listed (as many as fit
+ reasonably) on the actual cover, and continue the rest onto
+ adjacent pages.
+
+ If you publish or distribute Opaque copies of the Document
+ numbering more than 100, you must either include a
+ machine-readable Transparent copy along with each Opaque copy, or
+ state in or with each Opaque copy a computer-network location from
+ which the general network-using public has access to download
+ using public-standard network protocols a complete Transparent
+ copy of the Document, free of added material. If you use the
+ latter option, you must take reasonably prudent steps, when you
+ begin distribution of Opaque copies in quantity, to ensure that
+ this Transparent copy will remain thus accessible at the stated
+ location until at least one year after the last time you
+ distribute an Opaque copy (directly or through your agents or
+ retailers) of that edition to the public.
+
+ It is requested, but not required, that you contact the authors of
+ the Document well before redistributing any large number of
+ copies, to give them a chance to provide you with an updated
+ version of the Document.
+
+ 4. MODIFICATIONS
+
+ You may copy and distribute a Modified Version of the Document
+ under the conditions of sections 2 and 3 above, provided that you
+ release the Modified Version under precisely this License, with
+ the Modified Version filling the role of the Document, thus
+ licensing distribution and modification of the Modified Version to
+ whoever possesses a copy of it. In addition, you must do these
+ things in the Modified Version:
+
+ A. Use in the Title Page (and on the covers, if any) a title
+ distinct from that of the Document, and from those of
+ previous versions (which should, if there were any, be listed
+ in the History section of the Document). You may use the
+ same title as a previous version if the original publisher of
+ that version gives permission.
+
+ B. List on the Title Page, as authors, one or more persons or
+ entities responsible for authorship of the modifications in
+ the Modified Version, together with at least five of the
+ principal authors of the Document (all of its principal
+ authors, if it has fewer than five), unless they release you
+ from this requirement.
+
+ C. State on the Title page the name of the publisher of the
+ Modified Version, as the publisher.
+
+ D. Preserve all the copyright notices of the Document.
+
+ E. Add an appropriate copyright notice for your modifications
+ adjacent to the other copyright notices.
+
+ F. Include, immediately after the copyright notices, a license
+ notice giving the public permission to use the Modified
+ Version under the terms of this License, in the form shown in
+ the Addendum below.
+
+ G. Preserve in that license notice the full lists of Invariant
+ Sections and required Cover Texts given in the Document's
+ license notice.
+
+ H. Include an unaltered copy of this License.
+
+ I. Preserve the section Entitled "History", Preserve its Title,
+ and add to it an item stating at least the title, year, new
+ authors, and publisher of the Modified Version as given on
+ the Title Page. If there is no section Entitled "History" in
+ the Document, create one stating the title, year, authors,
+ and publisher of the Document as given on its Title Page,
+ then add an item describing the Modified Version as stated in
+ the previous sentence.
+
+ J. Preserve the network location, if any, given in the Document
+ for public access to a Transparent copy of the Document, and
+ likewise the network locations given in the Document for
+ previous versions it was based on. These may be placed in
+ the "History" section. You may omit a network location for a
+ work that was published at least four years before the
+ Document itself, or if the original publisher of the version
+ it refers to gives permission.
+
+ K. For any section Entitled "Acknowledgements" or "Dedications",
+ Preserve the Title of the section, and preserve in the
+ section all the substance and tone of each of the contributor
+ acknowledgements and/or dedications given therein.
+
+ L. Preserve all the Invariant Sections of the Document,
+ unaltered in their text and in their titles. Section numbers
+ or the equivalent are not considered part of the section
+ titles.
+
+ M. Delete any section Entitled "Endorsements". Such a section
+ may not be included in the Modified Version.
+
+ N. Do not retitle any existing section to be Entitled
+ "Endorsements" or to conflict in title with any Invariant
+ Section.
+
+ O. Preserve any Warranty Disclaimers.
+
+ If the Modified Version includes new front-matter sections or
+ appendices that qualify as Secondary Sections and contain no
+ material copied from the Document, you may at your option
+ designate some or all of these sections as invariant. To do this,
+ add their titles to the list of Invariant Sections in the Modified
+ Version's license notice. These titles must be distinct from any
+ other section titles.
+
+ You may add a section Entitled "Endorsements", provided it contains
+ nothing but endorsements of your Modified Version by various
+ parties--for example, statements of peer review or that the text
+ has been approved by an organization as the authoritative
+ definition of a standard.
+
+ You may add a passage of up to five words as a Front-Cover Text,
+ and a passage of up to 25 words as a Back-Cover Text, to the end
+ of the list of Cover Texts in the Modified Version. Only one
+ passage of Front-Cover Text and one of Back-Cover Text may be
+ added by (or through arrangements made by) any one entity. If the
+ Document already includes a cover text for the same cover,
+ previously added by you or by arrangement made by the same entity
+ you are acting on behalf of, you may not add another; but you may
+ replace the old one, on explicit permission from the previous
+ publisher that added the old one.
+
+ The author(s) and publisher(s) of the Document do not by this
+ License give permission to use their names for publicity for or to
+ assert or imply endorsement of any Modified Version.
+
+ 5. COMBINING DOCUMENTS
+
+ You may combine the Document with other documents released under
+ this License, under the terms defined in section 4 above for
+ modified versions, provided that you include in the combination
+ all of the Invariant Sections of all of the original documents,
+ unmodified, and list them all as Invariant Sections of your
+ combined work in its license notice, and that you preserve all
+ their Warranty Disclaimers.
+
+ The combined work need only contain one copy of this License, and
+ multiple identical Invariant Sections may be replaced with a single
+ copy. If there are multiple Invariant Sections with the same name
+ but different contents, make the title of each such section unique
+ by adding at the end of it, in parentheses, the name of the
+ original author or publisher of that section if known, or else a
+ unique number. Make the same adjustment to the section titles in
+ the list of Invariant Sections in the license notice of the
+ combined work.
+
+ In the combination, you must combine any sections Entitled
+ "History" in the various original documents, forming one section
+ Entitled "History"; likewise combine any sections Entitled
+ "Acknowledgements", and any sections Entitled "Dedications". You
+ must delete all sections Entitled "Endorsements."
+
+ 6. COLLECTIONS OF DOCUMENTS
+
+ You may make a collection consisting of the Document and other
+ documents released under this License, and replace the individual
+ copies of this License in the various documents with a single copy
+ that is included in the collection, provided that you follow the
+ rules of this License for verbatim copying of each of the
+ documents in all other respects.
+
+ You may extract a single document from such a collection, and
+ distribute it individually under this License, provided you insert
+ a copy of this License into the extracted document, and follow
+ this License in all other respects regarding verbatim copying of
+ that document.
+
+ 7. AGGREGATION WITH INDEPENDENT WORKS
+
+ A compilation of the Document or its derivatives with other
+ separate and independent documents or works, in or on a volume of
+ a storage or distribution medium, is called an "aggregate" if the
+ copyright resulting from the compilation is not used to limit the
+ legal rights of the compilation's users beyond what the individual
+ works permit. When the Document is included in an aggregate, this
+ License does not apply to the other works in the aggregate which
+ are not themselves derivative works of the Document.
+
+ If the Cover Text requirement of section 3 is applicable to these
+ copies of the Document, then if the Document is less than one half
+ of the entire aggregate, the Document's Cover Texts may be placed
+ on covers that bracket the Document within the aggregate, or the
+ electronic equivalent of covers if the Document is in electronic
+ form. Otherwise they must appear on printed covers that bracket
+ the whole aggregate.
+
+ 8. TRANSLATION
+
+ Translation is considered a kind of modification, so you may
+ distribute translations of the Document under the terms of section
+ 4. Replacing Invariant Sections with translations requires special
+ permission from their copyright holders, but you may include
+ translations of some or all Invariant Sections in addition to the
+ original versions of these Invariant Sections. You may include a
+ translation of this License, and all the license notices in the
+ Document, and any Warranty Disclaimers, provided that you also
+ include the original English version of this License and the
+ original versions of those notices and disclaimers. In case of a
+ disagreement between the translation and the original version of
+ this License or a notice or disclaimer, the original version will
+ prevail.
+
+ If a section in the Document is Entitled "Acknowledgements",
+ "Dedications", or "History", the requirement (section 4) to
+ Preserve its Title (section 1) will typically require changing the
+ actual title.
+
+ 9. TERMINATION
+
+ You may not copy, modify, sublicense, or distribute the Document
+ except as expressly provided under this License. Any attempt
+ otherwise to copy, modify, sublicense, or distribute it is void,
+ and will automatically terminate your rights under this License.
+
+ However, if you cease all violation of this License, then your
+ license from a particular copyright holder is reinstated (a)
+ provisionally, unless and until the copyright holder explicitly
+ and finally terminates your license, and (b) permanently, if the
+ copyright holder fails to notify you of the violation by some
+ reasonable means prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+ reinstated permanently if the copyright holder notifies you of the
+ violation by some reasonable means, this is the first time you have
+ received notice of violation of this License (for any work) from
+ that copyright holder, and you cure the violation prior to 30 days
+ after your receipt of the notice.
+
+ Termination of your rights under this section does not terminate
+ the licenses of parties who have received copies or rights from
+ you under this License. If your rights have been terminated and
+ not permanently reinstated, receipt of a copy of some or all of
+ the same material does not give you any rights to use it.
+
+ 10. FUTURE REVISIONS OF THIS LICENSE
+
+ The Free Software Foundation may publish new, revised versions of
+ the GNU Free Documentation License from time to time. Such new
+ versions will be similar in spirit to the present version, but may
+ differ in detail to address new problems or concerns. See
+ `http://www.gnu.org/copyleft/'.
+
+ Each version of the License is given a distinguishing version
+ number. If the Document specifies that a particular numbered
+ version of this License "or any later version" applies to it, you
+ have the option of following the terms and conditions either of
+ that specified version or of any later version that has been
+ published (not as a draft) by the Free Software Foundation. If
+ the Document does not specify a version number of this License,
+ you may choose any version ever published (not as a draft) by the
+ Free Software Foundation. If the Document specifies that a proxy
+ can decide which future versions of this License can be used, that
+ proxy's public statement of acceptance of a version permanently
+ authorizes you to choose that version for the Document.
+
+ 11. RELICENSING
+
+ "Massive Multiauthor Collaboration Site" (or "MMC Site") means any
+ World Wide Web server that publishes copyrightable works and also
+ provides prominent facilities for anybody to edit those works. A
+ public wiki that anybody can edit is an example of such a server.
+ A "Massive Multiauthor Collaboration" (or "MMC") contained in the
+ site means any set of copyrightable works thus published on the MMC
+ site.
+
+ "CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0
+ license published by Creative Commons Corporation, a not-for-profit
+ corporation with a principal place of business in San Francisco,
+ California, as well as future copyleft versions of that license
+ published by that same organization.
+
+ "Incorporate" means to publish or republish a Document, in whole or
+ in part, as part of another Document.
+
+ An MMC is "eligible for relicensing" if it is licensed under this
+ License, and if all works that were first published under this
+ License somewhere other than this MMC, and subsequently
+ incorporated in whole or in part into the MMC, (1) had no cover
+ texts or invariant sections, and (2) were thus incorporated prior
+ to November 1, 2008.
+
+ The operator of an MMC Site may republish an MMC contained in the
+ site under CC-BY-SA on the same site at any time before August 1,
+ 2009, provided the MMC is eligible for relicensing.
+
+
+ADDENDUM: How to use this License for your documents
+====================================================
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and license
+notices just after the title page:
+
+ Copyright (C) YEAR YOUR NAME.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+
+ If you have Invariant Sections, Front-Cover Texts and Back-Cover
+Texts, replace the "with...Texts." line with this:
+
+ with the Invariant Sections being LIST THEIR TITLES, with
+ the Front-Cover Texts being LIST, and with the Back-Cover Texts
+ being LIST.
+
+ If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+ If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License, to
+permit their use in free software.

+@node Introduction
+@chapter Introduction
+
+Automake is a tool for automatically generating @file{Makefile.in}s
+from files called @file{Makefile.am}. Each @file{Makefile.am} is
+basically a series of @command{make} variable
+definitions@footnote{These variables are also called @dfn{make macros}
+in Make terminology, however in this manual we reserve the term
+@dfn{macro} for Autoconf's macros.}, with rules being thrown in
+occasionally. The generated @file{Makefile.in}s are compliant with
+the GNU Makefile standards.
+
+@cindex GNU Makefile standards
+
+The GNU Makefile Standards Document
+(@pxref{Makefile Conventions, , , standards, The GNU Coding Standards})
+is long, complicated, and subject to change. The goal of Automake is to
+remove the burden of Makefile maintenance from the back of the
+individual GNU maintainer (and put it on the back of the Automake
+maintainers).
+
+The typical Automake input file is simply a series of variable definitions.
+Each such file is processed to create a @file{Makefile.in}. There
+should generally be one @file{Makefile.am} per directory of a project.
+
+@cindex Constraints of Automake
+@cindex Automake constraints
+
+Automake does constrain a project in certain ways; for instance, it
+assumes that the project uses Autoconf (@pxref{Top, , Introduction,
+autoconf, The Autoconf Manual}), and enforces certain restrictions on
+the @file{configure.ac} contents.
+
+@cindex Automake requirements
+@cindex Requirements, Automake

+@node Autotools Introduction
+@chapter An Introduction to the Autotools
+
+If you are new to Automake, maybe you know that it is part of a set of
+tools called @emph{The Autotools}. Maybe you've already delved into a
+package full of files named @file{configure}, @file{configure.ac},
+@file{Makefile.in}, @file{Makefile.am}, @file{aclocal.m4}, @dots{},
+some of them claiming to be @emph{generated by} Autoconf or Automake.
+But the exact purpose of these files and their relations is probably
+fuzzy. The goal of this chapter is to introduce you to this machinery,
+to show you how it works and how powerful it is. If you've never
+installed or seen such a package, do not worry: this chapter will walk
+you through it.
+
+If you need some teaching material, more illustrations, or a less
+@command{automake}-centered continuation, some slides for this
+introduction are available in Alexandre Duret-Lutz's
+@uref{http://www.lrde.epita.fr/@/~adl/@/autotools.html,
+Autotools Tutorial}.
+This chapter is the written version of the first part of his tutorial.

+@node GNU Build System
+@section Introducing the GNU Build System
+@cindex GNU Build System, introduction
+
+It is a truth universally acknowledged, that as a developer in
+possession of a new package, you must be in want of a build system.
+
+In the Unix world, such a build system is traditionally achieved using
+the command @command{make} (@pxref{Top, , Overview, make, The GNU Make
+Manual}). You express the recipe to build your package in a
+@file{Makefile}. This file is a set of rules to build the files in
+the package. For instance the program @file{prog} may be built by
+running the linker on the files @file{main.o}, @file{foo.o}, and
+@file{bar.o}; the file @file{main.o} may be built by running the
+compiler on @file{main.c}; etc. Each time @command{make} is run, it
+reads @file{Makefile}, checks the existence and modification time of
+the files mentioned, decides what files need to be built (or rebuilt),
+and runs the associated commands.
+
+When a package needs to be built on a different platform than the one
+it was developed on, its @file{Makefile} usually needs to be adjusted.
+For instance the compiler may have another name or require more
+options. In 1991, David J. MacKenzie got tired of customizing
+@file{Makefile} for the 20 platforms he had to deal with. Instead, he
+handcrafted a little shell script called @file{configure} to
+automatically adjust the @file{Makefile} (@pxref{Genesis, , Genesis,
+autoconf, The Autoconf Manual}). Compiling his package was now
+as simple as running @code{./configure && make}.
+
+@cindex GNU Coding Standards
+
+Today this process has been standardized in the GNU project. The GNU
+Coding Standards (@pxref{Managing Releases, The Release Process, ,
+standards, The GNU Coding Standards}) explains how each package of the
+GNU project should have a @file{configure} script, and the minimal
+interface it should have. The @file{Makefile} too should follow some
+established conventions. The result? A unified build system that
+makes all packages almost indistinguishable by the installer. In its
+simplest scenario, all the installer has to do is to unpack the
+package, run @code{./configure && make && make install}, and repeat
+with the next package to install.
+
+We call this build system the @dfn{GNU Build System}, since it was
+grown out of the GNU project. However it is used by a vast number of
+other packages: following any existing convention has its advantages.
+
+@cindex Autotools, introduction
+
+The Autotools are tools that will create a GNU Build System for your
+package. Autoconf mostly focuses on @file{configure} and Automake on
+@file{Makefile}s. It is entirely possible to create a GNU Build
+System without the help of these tools. However it is rather
+burdensome and error-prone. We will discuss this again after some
+illustration of the GNU Build System in action.
+
+@node Use Cases
+@section Use Cases for the GNU Build System
+@cindex GNU Build System, use cases
+@cindex GNU Build System, features
+@cindex Features of the GNU Build System
+@cindex Use Cases for the GNU Build System
+@cindex @file{amhello-1.0.tar.gz}, location
+@cindex @file{amhello-1.0.tar.gz}, use cases
+
+In this section we explore several use cases for the GNU Build System.
+You can replay all these examples on the @file{amhello-1.0.tar.gz}
+package distributed with Automake. If Automake is installed on your
+system, you should find a copy of this file in
+@file{@var{prefix}/share/doc/automake/amhello-1.0.tar.gz}, where
+@var{prefix} is the installation prefix specified during configuration
+(@var{prefix} defaults to @file{/usr/local}, however if Automake was
+installed by some GNU/Linux distribution it most likely has been set
+to @file{/usr}). If you do not have a copy of Automake installed,
+you can find a copy of this file inside the @file{doc/} directory of
+the Automake package.
+
+Some of the following use cases present features that are in fact
+extensions to the GNU Build System. Read: they are not specified by
+the GNU Coding Standards, but they are nonetheless part of the build
+system created by the Autotools. To keep things simple, we do not
+point out the difference. Our objective is to show you many of the
+features that the build system created by the Autotools will offer to
+you.

+@node Basic Installation
+@subsection Basic Installation
+@cindex Configuration, basics
+@cindex Installation, basics
+@cindex GNU Build System, basics
+
+The most common installation procedure looks as follows.
+
+@example
+~ % @kbd{tar zxf amhello-1.0.tar.gz}
+~ % @kbd{cd amhello-1.0}
+~/amhello-1.0 % @kbd{./configure}
+@dots{}
+config.status: creating Makefile
+config.status: creating src/Makefile
+@dots{}
+~/amhello-1.0 % @kbd{make}
+@dots{}
+~/amhello-1.0 % @kbd{make check}
+@dots{}
+~/amhello-1.0 % @kbd{su}
+Password:
+/home/adl/amhello-1.0 # @kbd{make install}
+@dots{}
+/home/adl/amhello-1.0 # @kbd{exit}
+~/amhello-1.0 % @kbd{make installcheck}
+@dots{}
+@end example
+
+@cindex Unpacking
+
+The user first unpacks the package. Here, and in the following
+examples, we will use the non-portable @code{tar zxf} command for
+simplicity. On a system without GNU @command{tar} installed, this
+command should read @code{gunzip -c amhello-1.0.tar.gz | tar xf -}.
+
+The user then enters the newly created directory to run the
+@file{configure} script. This script probes the system for various
+features, and finally creates the @file{Makefile}s. In this toy
+example there are only two @file{Makefile}s, but in real-world projects,
+there may be many more, usually one @file{Makefile} per directory.
+
+It is now possible to run @code{make}. This will construct all the
+programs, libraries, and scripts that need to be constructed for the
+package. In our example, this compiles the @file{hello} program.
+All files are constructed in place, in the source tree; we will see
+later how this can be changed.
+
+@code{make check} causes the package's tests to be run. This step is
+not mandatory, but it is often good to make sure the programs that
+have been built behave as they should, before you decide to install
+them. Our example does not contain any tests, so running @code{make
+check} is a no-op.
+
+@cindex su, before @code{make install}
+After everything has been built, and maybe tested, it is time to
+install it on the system. That means copying the programs,
+libraries, header files, scripts, and other data files from the
+source directory to their final destination on the system. The
+command @code{make install} will do that. However, by default
+everything will be installed in subdirectories of @file{/usr/local}:
+binaries will go into @file{/usr/local/bin}, libraries will end up in
+@file{/usr/local/lib}, etc. This destination is usually not writable
+by any user, so we assume that we have to become root before we can
+run @code{make install}. In our example, running @code{make install}
+will copy the program @file{hello} into @file{/usr/local/bin}
+and @file{README} into @file{/usr/local/share/doc/amhello}.
+
+A last and optional step is to run @code{make installcheck}. This
+command may run tests on the installed files. @code{make check} tests
+the files in the source tree, while @code{make installcheck} tests
+their installed copies. The tests run by the latter can be different
+from those run by the former. For instance, there are tests that
+cannot be run in the source tree. Conversely, some packages are set
+up so that @code{make installcheck} will run the very same tests as
+@code{make check}, only on different files (non-installed
+vs.@: installed). It can make a difference, for instance when the
+source tree's layout is different from that of the installation.
+Furthermore it may help to diagnose an incomplete installation.
+
+Presently most packages do not have any @code{installcheck} tests
+because the existence of @code{installcheck} is little known, and its
+usefulness is neglected. Our little toy package is no better: @code{make
+installcheck} does nothing.
+
+@node Standard Targets
+@subsection Standard @file{Makefile} Targets
+
+So far we have come across four ways to run @command{make} in the GNU
+Build System: @code{make}, @code{make check}, @code{make install}, and
+@code{make installcheck}. The words @code{check}, @code{install}, and
+@code{installcheck}, passed as arguments to @command{make}, are called
+@dfn{targets}. @code{make} is a shorthand for @code{make all},
+@code{all} being the default target in the GNU Build System.
+
+Here is a list of the most useful targets that the GNU Coding Standards
+specify.
+
+@table @code
+@item make all
+@trindex all
+Build programs, libraries, documentation, etc.@: (same as @code{make}).
+@item make install
+@trindex install
+Install what needs to be installed, copying the files from the
+package's tree to system-wide directories.
+@item make install-strip
+@trindex install-strip
+Same as @code{make install}, then strip debugging symbols. Some
+users like to trade space for useful bug reports@enddots{}
+@item make uninstall
+@trindex uninstall
+The opposite of @code{make install}: erase the installed files.
+(This needs to be run from the same build tree that was installed.)
+@item make clean
+@trindex clean
+Erase from the build tree the files built by @code{make all}.
+@item make distclean
+@trindex distclean
+Additionally erase anything @code{./configure} created.
+@item make check
+@trindex check
+Run the test suite, if any.
+@item make installcheck
+@trindex installcheck
+Check the installed programs or libraries, if supported.
+@item make dist
+@trindex dist
+Recreate @file{@var{package}-@var{version}.tar.gz} from all the source
+files.
+@end table
+
+@node Standard Directory Variables
+@subsection Standard Directory Variables
+@cindex directory variables
+
+The GNU Coding Standards also specify a hierarchy of variables to
+denote installation directories. Some of these are:
+
+@multitable {Directory variable} {@code{$@{datarootdir@}/doc/$@{PACKAGE@}}}
+@headitem Directory variable @tab Default value
+@item @code{prefix} @tab @code{/usr/local}
+@item @w{@ @ @code{exec_prefix}} @tab @code{$@{prefix@}}
+@item @w{@ @ @ @ @code{bindir}} @tab @code{$@{exec_prefix@}/bin}
+@item @w{@ @ @ @ @code{libdir}} @tab @code{$@{exec_prefix@}/lib}
+@item @w{@ @ @ @ @dots{}}
+@item @w{@ @ @code{includedir}} @tab @code{$@{prefix@}/include}
+@item @w{@ @ @code{datarootdir}} @tab @code{$@{prefix@}/share}
+@item @w{@ @ @ @ @code{datadir}} @tab @code{$@{datarootdir@}}
+@item @w{@ @ @ @ @code{mandir}} @tab @code{$@{datarootdir@}/man}
+@item @w{@ @ @ @ @code{infodir}} @tab @code{$@{datarootdir@}/info}
+@item @w{@ @ @ @ @code{docdir}} @tab @code{$@{datarootdir@}/doc/$@{PACKAGE@}}
+@item @w{@ @ @dots{}}
+@end multitable
+
+@c We should provide a complete table somewhere, but not here. The
+@c complete list of directory variables it too confusing as-is. It
+@c requires some explanations that are too complicated for this
+@c introduction. Besides listing directories like localstatedir
+@c would make the explanations in ``Two-Part Install'' harder.
+
+Each of these directories has a role which is often obvious from its
+name. In a package, any installable file will be installed in one of
+these directories. For instance in @code{amhello-1.0}, the program
+@file{hello} is to be installed in @var{bindir}, the directory for
+binaries. The default value for this directory is
+@file{/usr/local/bin}, but the user can supply a different value when
+calling @command{configure}. Also the file @file{README} will be
+installed into @var{docdir}, which defaults to
+@file{/usr/local/share/doc/amhello}.
+
+@opindex --prefix
+
+As a user, if you wish to install a package on your own account, you
+could proceed as follows:
+
+@example
+~/amhello-1.0 % @kbd{./configure --prefix ~/usr}
+@dots{}
+~/amhello-1.0 % @kbd{make}
+@dots{}
+~/amhello-1.0 % @kbd{make install}
+@dots{}
+@end example
+
+This would install @file{~/usr/bin/hello} and
+@file{~/usr/share/doc/amhello/README}.
+
+The list of all such directory options is shown by
+@code{./configure --help}.
+
+@node Standard Configuration Variables
+@subsection Standard Configuration Variables
+@cindex configuration variables, overriding
+
+The GNU Coding Standards also define a set of standard configuration
+variables used during the build. Here are some:
+
+@table @asis
+@item @code{CC}
+C compiler command
+@item @code{CFLAGS}
+C compiler flags
+@item @code{CXX}
+C++ compiler command
+@item @code{CXXFLAGS}
+C++ compiler flags
+@item @code{LDFLAGS}
+linker flags
+@item @code{CPPFLAGS}
+C/C++ preprocessor flags
+@item @dots{}
+@end table
+
+@command{configure} usually does a good job at setting appropriate
+values for these variables, but there are cases where you may want to
+override them. For instance you may have several versions of a
+compiler installed and would like to use another one, you may have
+header files installed outside the default search path of the
+compiler, or even libraries out of the way of the linker.
+
+Here is how one would call @command{configure} to force it to use
+@command{gcc-3} as C compiler, use header files from
+@file{~/usr/include} when compiling, and libraries from
+@file{~/usr/lib} when linking.
+
+@example
+~/amhello-1.0 % @kbd{./configure --prefix ~/usr CC=gcc-3 \
+CPPFLAGS=-I$HOME/usr/include LDFLAGS=-L$HOME/usr/lib}
+@end example
+
+Again, a full list of these variables appears in the output of
+@code{./configure --help}.
+
+@node config.site
+@subsection Overriding Default Configuration Setting with @file{config.site}
+@cindex @file{config.site} example
+
+When installing several packages using the same setup, it can be
+convenient to create a file to capture common settings.
+If a file named @file{@var{prefix}/share/config.site} exists,
+@command{configure} will source it at the beginning of its execution.
+
+Recall the command from the previous section:
+
+@example
+~/amhello-1.0 % @kbd{./configure --prefix ~/usr CC=gcc-3 \
+CPPFLAGS=-I$HOME/usr/include LDFLAGS=-L$HOME/usr/lib}
+@end example
+
+Assuming we are installing many package in @file{~/usr}, and will
+always want to use these definitions of @code{CC}, @code{CPPFLAGS}, and
+@code{LDFLAGS}, we can automate this by creating the following
+@file{~/usr/share/config.site} file:
+
+@example
+test -z "$CC" && CC=gcc-3
+test -z "$CPPFLAGS" && CPPFLAGS=-I$HOME/usr/include
+test -z "$LDFLAGS" && LDFLAGS=-L$HOME/usr/lib
+@end example
+
+Now, any time a @file{configure} script is using the @file{~/usr}
+prefix, it will execute the above @file{config.site} and define
+these three variables.
+
+@example
+~/amhello-1.0 % @kbd{./configure --prefix ~/usr}
+configure: loading site script /home/adl/usr/share/config.site
+@dots{}
+@end example
+
+@xref{Site Defaults, , Setting Site Defaults, autoconf, The Autoconf
+Manual}, for more information about this feature.
+
+
+@node VPATH Builds
+@subsection Parallel Build Trees (a.k.a.@: VPATH Builds)
+@cindex Parallel build trees
+@cindex VPATH builds
+@cindex source tree and build tree
+@cindex build tree and source tree
+@cindex trees, source vs.@: build
+
+The GNU Build System distinguishes two trees: the source tree, and
+the build tree.
+
+The source tree is rooted in the directory containing
+@file{configure}. It contains all the sources files (those that are
+distributed), and may be arranged using several subdirectories.
+
+The build tree is rooted in the directory in which @file{configure}
+was run, and is populated with all object files, programs, libraries,
+and other derived files built from the sources (and hence not
+distributed). The build tree usually has the same subdirectory layout
+as the source tree; its subdirectories are created automatically by
+the build system.
+
+If @file{configure} is executed in its own directory, the source and
+build trees are combined: derived files are constructed in the same
+directories as their sources. This was the case in our first
+installation example (@pxref{Basic Installation}).
+
+A common request from users is that they want to confine all derived
+files to a single directory, to keep their source directories
+uncluttered. Here is how we could run @file{configure} to build
+everything in a subdirectory called @file{build/}.
+
+@example
+~ % @kbd{tar zxf ~/amhello-1.0.tar.gz}
+~ % @kbd{cd amhello-1.0}
+~/amhello-1.0 % @kbd{mkdir build && cd build}
+~/amhello-1.0/build % @kbd{../configure}
+@dots{}
+~/amhello-1.0/build % @kbd{make}
+@dots{}
+@end example
+
+These setups, where source and build trees are different, are often
+called @dfn{parallel builds} or @dfn{VPATH builds}. The expression
+@emph{parallel build} is misleading: the word @emph{parallel} is a
+reference to the way the build tree shadows the source tree, it is not
+about some concurrency in the way build commands are run. For this
+reason we refer to such setups using the name @emph{VPATH builds} in
+the following. @emph{VPATH} is the name of the @command{make} feature
+used by the @file{Makefile}s to allow these builds (@pxref{General
+Search, , @code{VPATH} Search Path for All Prerequisites, make, The
+GNU Make Manual}).
+
+@cindex multiple configurations, example
+@cindex debug build, example
+@cindex optimized build, example
+
+VPATH builds have other interesting uses. One is to build the same
+sources with multiple configurations. For instance:
+
+@c Keep in sync with amhello-cflags.sh
+@example
+~ % @kbd{tar zxf ~/amhello-1.0.tar.gz}
+~ % @kbd{cd amhello-1.0}
+~/amhello-1.0 % @kbd{mkdir debug optim && cd debug}
+~/amhello-1.0/debug % @kbd{../configure CFLAGS='-g -O0'}
+@dots{}
+~/amhello-1.0/debug % @kbd{make}
+@dots{}
+~/amhello-1.0/debug % cd ../optim
+~/amhello-1.0/optim % @kbd{../configure CFLAGS='-O3 -fomit-frame-pointer'}
+@dots{}
+~/amhello-1.0/optim % @kbd{make}
+@dots{}
+@end example
+
+With network file systems, a similar approach can be used to build the
+same sources on different machines. For instance, suppose that the
+sources are installed on a directory shared by two hosts: @code{HOST1}
+and @code{HOST2}, which may be different platforms.
+
+@example
+~ % @kbd{cd /nfs/src}
+/nfs/src % @kbd{tar zxf ~/amhello-1.0.tar.gz}
+@end example
+
+On the first host, you could create a local build directory:
+@example
+[HOST1] ~ % @kbd{mkdir /tmp/amh && cd /tmp/amh}
+[HOST1] /tmp/amh % @kbd{/nfs/src/amhello-1.0/configure}
+...
+[HOST1] /tmp/amh % @kbd{make && sudo make install}
+...
+@end example
+
+@noindent
+(Here we assume that the installer has configured @command{sudo} so it
+can execute @code{make install} with root privileges; it is more convenient
+than using @command{su} like in @ref{Basic Installation}).
+
+On the second host, you would do exactly the same, possibly at
+the same time:
+@example
+[HOST2] ~ % @kbd{mkdir /tmp/amh && cd /tmp/amh}
+[HOST2] /tmp/amh % @kbd{/nfs/src/amhello-1.0/configure}
+...
+[HOST2] /tmp/amh % @kbd{make && sudo make install}
+...
+@end example
+
+@cindex read-only source tree
+@cindex source tree, read-only
+
+In this scenario, nothing forbids the @file{/nfs/src/amhello-1.0}
+directory from being read-only. In fact VPATH builds are also a means
+of building packages from a read-only medium such as a CD-ROM. (The
+FSF used to sell CD-ROM with unpacked source code, before the GNU
+project grew so big.)
+
+@node Two-Part Install
+@subsection Two-Part Installation
+
+In our last example (@pxref{VPATH Builds}), a source tree was shared
+by two hosts, but compilation and installation were done separately on
+each host.
+
+The GNU Build System also supports networked setups where part of the
+installed files should be shared amongst multiple hosts. It does so
+by distinguishing architecture-dependent files from
+architecture-independent files, and providing two @file{Makefile}
+targets to install each of these classes of files.
+
+@trindex install-exec
+@trindex install-data
+
+These targets are @code{install-exec} for architecture-dependent files
+and @code{install-data} for architecture-independent files.
+The command we used up to now, @code{make install}, can be thought of
+as a shorthand for @code{make install-exec install-data}.
+
+From the GNU Build System point of view, the distinction between
+architecture-dependent files and architecture-independent files is
+based exclusively on the directory variable used to specify their
+installation destination. In the list of directory variables we
+provided earlier (@pxref{Standard Directory Variables}), all the
+variables based on @var{exec-prefix} designate architecture-dependent
+directories whose files will be installed by @code{make install-exec}.
+The others designate architecture-independent directories and will
+serve files installed by @code{make install-data}. @xref{The Two Parts
+of Install}, for more details.
+
+Here is how we could revisit our two-host installation example,
+assuming that (1) we want to install the package directly in
+@file{/usr}, and (2) the directory @file{/usr/share} is shared by the
+two hosts.
+
+On the first host we would run
+@example
+[HOST1] ~ % @kbd{mkdir /tmp/amh && cd /tmp/amh}
+[HOST1] /tmp/amh % @kbd{/nfs/src/amhello-1.0/configure --prefix /usr}
+...
+[HOST1] /tmp/amh % @kbd{make && sudo make install}
+...
+@end example
+
+On the second host, however, we need only install the
+architecture-specific files.
+@example
+[HOST2] ~ % @kbd{mkdir /tmp/amh && cd /tmp/amh}
+[HOST2] /tmp/amh % @kbd{/nfs/src/amhello-1.0/configure --prefix /usr}
+...
+[HOST2] /tmp/amh % @kbd{make && sudo make install-exec}
+...
+@end example
+
+In packages that have installation checks, it would make sense to run
+@code{make installcheck} (@pxref{Basic Installation}) to verify that
+the package works correctly despite the apparent partial installation.
+
+@node Cross-Compilation
+@subsection Cross-Compilation
+@cindex cross-compilation
+
+To @dfn{cross-compile} is to build on one platform a binary that will
+run on another platform. When speaking of cross-compilation, it is
+important to distinguish between the @dfn{build platform} on which
+the compilation is performed, and the @dfn{host platform} on which the
+resulting executable is expected to run. The following
+@command{configure} options are used to specify each of them:
+
+@table @option
+@item --build=@var{build}
+@opindex --build=@var{build}
+The system on which the package is built.
+@item --host=@var{host}
+@opindex --host=@var{host}
+The system where built programs and libraries will run.
+@end table
+
+When the @option{--host} is used, @command{configure} will search for
+the cross-compiling suite for this platform. Cross-compilation tools
+commonly have their target architecture as prefix of their name. For
+instance my cross-compiler for MinGW32 has its binaries called
+@code{i586-mingw32msvc-gcc}, @code{i586-mingw32msvc-ld},
+@code{i586-mingw32msvc-as}, etc.
+
+@cindex MinGW cross-compilation example
+@cindex cross-compilation example
+
+Here is how we could build @code{amhello-1.0} for
+@code{i586-mingw32msvc} on a GNU/Linux PC.
+
+@c Keep in sync with amhello-cross-compile.sh
+@smallexample
+~/amhello-1.0 % @kbd{./configure --build i686-pc-linux-gnu --host i586-mingw32msvc}

+@node Renaming
+@subsection Renaming Programs at Install Time
+@cindex Renaming programs
+@cindex Transforming program names
+@cindex Programs, renaming during installation
+
+The GNU Build System provides means to automatically rename
+executables and manpages before they are installed (@pxref{Man Pages}).
+This is especially convenient
+when installing a GNU package on a system that already has a
+proprietary implementation you do not want to overwrite. For instance,
+you may want to install GNU @command{tar} as @command{gtar} so you can
+distinguish it from your vendor's @command{tar}.
+
+This can be done using one of these three @command{configure} options.
+
+@table @option
+@item --program-prefix=@var{prefix}
+@opindex --program-prefix=@var{prefix}
+Prepend @var{prefix} to installed program names.
+@item --program-suffix=@var{suffix}

+@item --program-transform-name=@var{program}
+@opindex --program-transform-name=@var{program}
+Run @code{sed @var{program}} on installed program names.
+@end table
+
+The following commands would install @file{hello}
+as @file{/usr/local/bin/test-hello}, for instance.
+
+@example

+
+@node DESTDIR
+@subsection Building Binary Packages Using DESTDIR
+@vindex DESTDIR
+
+The GNU Build System's @code{make install} and @code{make uninstall}
+interface does not exactly fit the needs of a system administrator
+who has to deploy and upgrade packages on lots of hosts. In other
+words, the GNU Build System does not replace a package manager.
+
+Such package managers usually need to know which files have been
+installed by a package, so a mere @code{make install} is
+inappropriate.
+
+@cindex Staged installation
+
+The @code{DESTDIR} variable can be used to perform a staged
+installation. The package should be configured as if it was going to
+be installed in its final location (e.g., @code{--prefix /usr}), but
+when running @code{make install}, the @code{DESTDIR} should be set to
+the absolute name of a directory into which the installation will be
+diverted. From this directory it is easy to review which files are
+being installed where, and finally copy them to their final location
+by some means.
+
+@cindex Binary package
+
+For instance here is how we could create a binary package containing a
+snapshot of all the files to be installed.
+
+@c Keep in sync with amhello-binpkg.sh
+@example
+~/amhello-1.0 % @kbd{./configure --prefix /usr}
+@dots{}
+~/amhello-1.0 % @kbd{make}
+@dots{}
+~/amhello-1.0 % @kbd{make DESTDIR=$HOME/inst install}
+@dots{}
+~/amhello-1.0 % @kbd{cd ~/inst}
+~/inst % @kbd{find . -type f -print > ../files.lst}
+~/inst % @kbd{tar zcvf ~/amhello-1.0-i686.tar.gz `cat ../files.lst`}
+./usr/bin/hello
+./usr/share/doc/amhello/README
+@end example
+
+After this example, @code{amhello-1.0-i686.tar.gz} is ready to be
+uncompressed in @file{/} on many hosts. (Using @code{`cat ../files.lst`}
+instead of @samp{.} as argument for @command{tar} avoids entries for
+each subdirectory in the archive: we would not like @command{tar} to
+restore the modification time of @file{/}, @file{/usr/}, etc.)
+
+Note that when building packages for several architectures, it might
+be convenient to use @code{make install-data} and @code{make
+install-exec} (@pxref{Two-Part Install}) to gather
+architecture-independent files in a single package.
+
+@xref{Install}, for more information.
+
+@c We should document PRE_INSTALL/POST_INSTALL/NORMAL_INSTALL and their
+@c UNINSTALL counterparts.
+
+@node Preparing Distributions
+@subsection Preparing Distributions
+@cindex Preparing distributions
+@cindex Packages, preparation
+@cindex Distributions, preparation
+
+We have already mentioned @code{make dist}. This target collects all
+your source files and the necessary parts of the build system to
+create a tarball named @file{@var{package}-@var{version}.tar.gz}.
+
+@cindex @code{distcheck} better than @code{dist}
+
+Another, more useful command is @code{make distcheck}. The
+@code{distcheck} target constructs
+@file{@var{package}-@var{version}.tar.gz} just as well as @code{dist},
+but it additionally ensures most of the use cases presented so far
+work:
+
+@itemize @bullet
+@item
+It attempts a full compilation of the package (@pxref{Basic
+Installation}), unpacking the newly constructed tarball, running
+@code{make}, @code{make check}, @code{make install}, as well as

+@item
+it tests VPATH builds with read-only source tree (@pxref{VPATH Builds}),
+@item
+it makes sure @code{make clean}, @code{make distclean}, and @code{make

+@item
+and it checks that @code{DESTDIR} installations work (@pxref{DESTDIR}).
+@end itemize
+
+All of these actions are performed in a temporary subdirectory, so
+that no root privileges are required.
+
+Releasing a package that fails @code{make distcheck} means that one of
+the scenarios we presented will not work and some users will be
+disappointed. Therefore it is a good practice to release a package
+only after a successful @code{make distcheck}. This of course does
+not imply that the package will be flawless, but at least it will
+prevent some of the embarrassing errors you may find in packages
+released by people who have never heard about @code{distcheck} (like
+@code{DESTDIR} not working because of a typo, or a distributed file
+being erased by @code{make clean}, or even @code{VPATH} builds not
+working).

+
+@node Dependency Tracking
+@subsection Automatic Dependency Tracking
+@cindex Dependency tracking
+
+Dependency tracking is performed as a side-effect of compilation.
+Each time the build system compiles a source file, it computes its
+list of dependencies (in C these are the header files included by the
+source being compiled). Later, any time @command{make} is run and a
+dependency appears to have changed, the dependent files will be
+rebuilt.
+
+Automake generates code for automatic dependency tracking by default,
+unless the developer chooses to override it; for more information,
+@pxref{Dependencies}.
+
+When @command{configure} is executed, you can see it probing each
+compiler for the dependency mechanism it supports (several mechanisms
+can be used):
+
+@example
+~/amhello-1.0 % @kbd{./configure --prefix /usr}
+@dots{}
+checking dependency style of gcc... gcc3
+@dots{}
+@end example
+
+Because dependencies are only computed as a side-effect of the
+compilation, no dependency information exists the first time a package
+is built. This is OK because all the files need to be built anyway:
+@code{make} does not have to decide which files need to be rebuilt.
+In fact, dependency tracking is completely useless for one-time builds
+and there is a @command{configure} option to disable this:
+
+@table @option
+@item --disable-dependency-tracking
+@opindex --disable-dependency-tracking
+Speed up one-time builds.
+@end table
+
+Some compilers do not offer any practical way to derive the list of
+dependencies as a side-effect of the compilation, requiring a separate
+run (maybe of another tool) to compute these dependencies. The
+performance penalty implied by these methods is important enough to
+disable them by default. The option @option{--enable-dependency-tracking}
+must be passed to @command{configure} to activate them.
+
+@table @option
+@item --enable-dependency-tracking
+@opindex --enable-dependency-tracking
+Do not reject slow dependency extractors.

+@node Nested Packages
+@subsection Nested Packages
+@cindex Nested packages
+@cindex Packages, nested
+@cindex Subpackages
+
+Although nesting packages isn't something we would recommend to
+someone who is discovering the Autotools, it is a nice feature worthy
+of mention in this small advertising tour.
+
+Autoconfiscated packages (that means packages whose build system have
+been created by Autoconf and friends) can be nested to arbitrary
+depth.
+
+A typical setup is that package A will distribute one of the libraries
+it needs in a subdirectory. This library B is a complete package with
+its own GNU Build System. The @command{configure} script of A will
+run the @command{configure} script of B as part of its execution,
+building and installing A will also build and install B. Generating a
+distribution for A will also include B.
+
+It is possible to gather several packages like this. GCC is a heavy
+user of this feature. This gives installers a single package to
+configure, build and install, while it allows developers to work on
+subpackages independently.
+
+When configuring nested packages, the @command{configure} options
+given to the top-level @command{configure} are passed recursively to
+nested @command{configure}s. A package that does not understand an
+option will ignore it, assuming it is meaningful to some other
+package.
+
+@opindex --help=recursive
+
+The command @code{configure --help=recursive} can be used to display
+the options supported by all the included packages.

+@node Creating amhello
+@subsection Creating @file{amhello-1.0.tar.gz}
+
+Here is how we can recreate @file{amhello-1.0.tar.gz} from scratch.
+The package is simple enough so that we will only need to write 5
+files. (You may copy them from the final @file{amhello-1.0.tar.gz}
+that is distributed with Automake if you do not want to write them.)
+
+Create the following files in an empty directory.
+
+@itemize @bullet
+
+@item
+@file{src/main.c} is the source file for the @file{hello} program. We
+store it in the @file{src/} subdirectory, because later, when the package
+evolves, it will ease the addition of a @file{man/} directory for man
+pages, a @file{data/} directory for data files, etc.
+@example
+~/amhello % @kbd{cat src/main.c}
+#include <config.h>
+#include <stdio.h>
+
+int
+main (void)
+@{
+ puts ("Hello World!");
+ puts ("This is " PACKAGE_STRING ".");
+ return 0;
+@}
+@end example
+
+@item
+@file{README} contains some very limited documentation for our little
+package.
+@example
+~/amhello % @kbd{cat README}
+This is a demonstration package for GNU Automake.
+Type `info Automake' to read the Automake manual.
+@end example
+
+@item
+@file{Makefile.am} and @file{src/Makefile.am} contain Automake
+instructions for these two directories.
+
+@example
+~/amhello % @kbd{cat src/Makefile.am}
+bin_PROGRAMS = hello
+hello_SOURCES = main.c
+~/amhello % @kbd{cat Makefile.am}
+SUBDIRS = src
+dist_doc_DATA = README
+@end example
+
+@item
+Finally, @file{configure.ac} contains Autoconf instructions to
+create the @command{configure} script.
+
+@example
+~/amhello % @kbd{cat configure.ac}
+AC_INIT([amhello], [1.0], [@value{PACKAGE_BUGREPORT}])
+AM_INIT_AUTOMAKE([-Wall -Werror foreign])
+AC_PROG_CC
+AC_CONFIG_HEADERS([config.h])
+AC_CONFIG_FILES([
+ Makefile
+ src/Makefile
+])
+AC_OUTPUT
+@end example
+@end itemize
+
+@cindex @command{autoreconf}, example
+
+Once you have these five files, it is time to run the Autotools to
+instantiate the build system. Do this using the @command{autoreconf}
+command as follows:
+
+@example
+~/amhello % @kbd{autoreconf --install}
+configure.ac: installing `./install-sh'
+configure.ac: installing `./missing'
+src/Makefile.am: installing `./depcomp'
+@end example
+
+At this point the build system is complete.
+
+In addition to the three scripts mentioned in its output, you can see
+that @command{autoreconf} created four other files: @file{configure},
+@file{config.h.in}, @file{Makefile.in}, and @file{src/Makefile.in}.
+The latter three files are templates that will be adapted to the
+system by @command{configure} under the names @file{config.h},
+@file{Makefile}, and @file{src/Makefile}. Let's do this:
+
+@example
+~/amhello % @kbd{./configure}
+checking for a BSD-compatible install... /usr/bin/install -c
+checking whether build environment is sane... yes
+checking for gawk... no
+checking for mawk... mawk
+checking whether make sets $(MAKE)... yes
+checking for gcc... gcc
+checking for C compiler default output file name... a.out
+checking whether the C compiler works... yes
+checking whether we are cross compiling... no
+checking for suffix of executables...
+checking for suffix of object files... o
+checking whether we are using the GNU C compiler... yes
+checking whether gcc accepts -g... yes
+checking for gcc option to accept ISO C89... none needed
+checking for style of include used by make... GNU
+checking dependency style of gcc... gcc3
+configure: creating ./config.status
+config.status: creating Makefile
+config.status: creating src/Makefile
+config.status: creating config.h
+config.status: executing depfiles commands
+@end example
+
+@trindex distcheck
+@cindex @code{distcheck} example
+
+You can see @file{Makefile}, @file{src/Makefile}, and @file{config.h}
+being created at the end after @command{configure} has probed the
+system. It is now possible to run all the targets we wish
+(@pxref{Standard Targets}). For instance:
+
+@example
+~/amhello % @kbd{make}
+@dots{}
+~/amhello % @kbd{src/hello}
+Hello World!
+This is amhello 1.0.
+~/amhello % @kbd{make distcheck}
+@dots{}

+@end example
+
+Note that running @command{autoreconf} is only needed initially when
+the GNU Build System does not exist. When you later change some
+instructions in a @file{Makefile.am} or @file{configure.ac}, the
+relevant part of the build system will be regenerated automatically
+when you execute @command{make}.
+
+@command{autoreconf} is a script that calls @command{autoconf},
+@command{automake}, and a bunch of other commands in the right order.
+If you are beginning with these tools, it is not important to figure
+out in which order all these tools should be invoked and why. However,
+because Autoconf and Automake have separate manuals, the important
+point to understand is that @command{autoconf} is in charge of
+creating @file{configure} from @file{configure.ac}, while
+@command{automake} is in charge of creating @file{Makefile.in}s from
+@file{Makefile.am}s and @file{configure.ac}. This should at least
+direct you to the right manual when seeking answers.

+
+@node amhello's configure.ac Setup Explained
+@subsection @code{amhello}'s @file{configure.ac} Setup Explained

+@cindex @file{configure.ac}, Hello World
+
+Let us begin with the contents of @file{configure.ac}.
+
+@example
+AC_INIT([amhello], [1.0], [@value{PACKAGE_BUGREPORT}])
+AM_INIT_AUTOMAKE([-Wall -Werror foreign])
+AC_PROG_CC
+AC_CONFIG_HEADERS([config.h])
+AC_CONFIG_FILES([
+ Makefile
+ src/Makefile
+])
+AC_OUTPUT
+@end example
+
+This file is read by both @command{autoconf} (to create
+@file{configure}) and @command{automake} (to create the various
+@file{Makefile.in}s). It contains a series of M4 macros that will be
+expanded as shell code to finally form the @file{configure} script.
+We will not elaborate on the syntax of this file, because the Autoconf
+manual has a whole section about it (@pxref{Writing Autoconf Input, ,
+Writing @file{configure.ac}, autoconf, The Autoconf Manual}).
+
+The macros prefixed with @code{AC_} are Autoconf macros, documented
+in the Autoconf manual (@pxref{Autoconf Macro Index, , Autoconf Macro
+Index, autoconf, The Autoconf Manual}). The macros that start with
+@code{AM_} are Automake macros, documented later in this manual
+(@pxref{Macro Index}).
+
+The first two lines of @file{configure.ac} initialize Autoconf and
+Automake. @code{AC_INIT} takes in as parameters the name of the package,
+its version number, and a contact address for bug-reports about the
+package (this address is output at the end of @code{./configure
+--help}, for instance). When adapting this setup to your own package,
+by all means please do not blindly copy Automake's address: use the
+mailing list of your package, or your own mail address.
+
+@opindex -Wall
+@opindex -Werror
+@opindex foreign
+
+The argument to @code{AM_INIT_AUTOMAKE} is a list of options for
+@command{automake} (@pxref{Options}). @option{-Wall} and
+@option{-Werror} ask @command{automake} to turn on all warnings and
+report them as errors. We are speaking of @strong{Automake} warnings
+here, such as dubious instructions in @file{Makefile.am}. This has
+absolutely nothing to do with how the compiler will be called, even
+though it may support options with similar names. Using @option{-Wall
+-Werror} is a safe setting when starting to work on a package: you do
+not want to miss any issues. Later you may decide to relax things a
+bit. The @option{foreign} option tells Automake that this package
+will not follow the GNU Standards. GNU packages should always
+distribute additional files such as @file{ChangeLog}, @file{AUTHORS},
+etc. We do not want @command{automake} to complain about these
+missing files in our small example.
+
+The @code{AC_PROG_CC} line causes the @command{configure} script to
+search for a C compiler and define the variable @code{CC} with its
+name. The @file{src/Makefile.in} file generated by Automake uses the
+variable @code{CC} to build @file{hello}, so when @command{configure}
+creates @file{src/Makefile} from @file{src/Makefile.in}, it will define
+@code{CC} with the value it has found. If Automake is asked to create
+a @file{Makefile.in} that uses @code{CC} but @file{configure.ac} does
+not define it, it will suggest you add a call to @code{AC_PROG_CC}.
+
+The @code{AC_CONFIG_HEADERS([config.h])} invocation causes the
+@command{configure} script to create a @file{config.h} file gathering
+@samp{#define}s defined by other macros in @file{configure.ac}. In our
+case, the @code{AC_INIT} macro already defined a few of them. Here
+is an excerpt of @file{config.h} after @command{configure} has run:
+
+@smallexample
+@dots{}
+/* Define to the address where bug reports for this package should be sent. */
+#define PACKAGE_BUGREPORT "@value{PACKAGE_BUGREPORT}"
+
+/* Define to the full name and version of this package. */
+#define PACKAGE_STRING "amhello 1.0"
+@dots{}
+@end smallexample
+
+As you probably noticed, @file{src/main.c} includes @file{config.h} so
+it can use @code{PACKAGE_STRING}. In a real-world project,
+@file{config.h} can grow really big, with one @samp{#define} per
+feature probed on the system.
+
+The @code{AC_CONFIG_FILES} macro declares the list of files that
+@command{configure} should create from their @file{*.in} templates.
+Automake also scans this list to find the @file{Makefile.am} files it must
+process. (This is important to remember: when adding a new directory
+to your project, you should add its @file{Makefile} to this list,
+otherwise Automake will never process the new @file{Makefile.am} you
+wrote in that directory.)
+
+Finally, the @code{AC_OUTPUT} line is a closing command that actually
+produces the part of the script in charge of creating the files
+registered with @code{AC_CONFIG_HEADERS} and @code{AC_CONFIG_FILES}.
+
+@cindex @command{autoscan}
+
+When starting a new project, we suggest you start with such a simple
+@file{configure.ac}, and gradually add the other tests it requires.
+The command @command{autoscan} can also suggest a few of the tests
+your package may need (@pxref{autoscan Invocation, , Using
+@command{autoscan} to Create @file{configure.ac}, autoconf, The
+Autoconf Manual}).
+
+
+@node amhello's Makefile.am Setup Explained
+@subsection @code{amhello}'s @file{Makefile.am} Setup Explained
+
+@cindex @file{Makefile.am}, Hello World
+
+We now turn to @file{src/Makefile.am}. This file contains
+Automake instructions to build and install @file{hello}.
+
+@example
+bin_PROGRAMS = hello
+hello_SOURCES = main.c
+@end example
+
+A @file{Makefile.am} has the same syntax as an ordinary
+@file{Makefile}. When @command{automake} processes a
+@file{Makefile.am} it copies the entire file into the output
+@file{Makefile.in} (that will be later turned into @file{Makefile} by
+@command{configure}) but will react to certain variable definitions
+by generating some build rules and other variables.
+Often @file{Makefile.am}s contain only a list of variable definitions as
+above, but they can also contain other variable and rule definitions that
+@command{automake} will pass along without interpretation.
+
+Variables that end with @code{_PROGRAMS} are special variables
+that list programs that the resulting @file{Makefile} should build.
+In Automake speak, this @code{_PROGRAMS} suffix is called a
+@dfn{primary}; Automake recognizes other primaries such as
+@code{_SCRIPTS}, @code{_DATA}, @code{_LIBRARIES}, etc.@: corresponding
+to different types of files.
+
+The @samp{bin} part of the @code{bin_PROGRAMS} tells
+@command{automake} that the resulting programs should be installed in
+@var{bindir}. Recall that the GNU Build System uses a set of variables
+to denote destination directories and allow users to customize these
+locations (@pxref{Standard Directory Variables}). Any such directory
+variable can be put in front of a primary (omitting the @code{dir}
+suffix) to tell @command{automake} where to install the listed files.
+
+Programs need to be built from source files, so for each program
+@code{@var{prog}} listed in a @code{@w{_PROGRAMS}} variable,
+@command{automake} will look for another variable named
+@code{@var{prog}_SOURCES} listing its source files. There may be more
+than one source file: they will all be compiled and linked together.
+
+Automake also knows that source files need to be distributed when
+creating a tarball (unlike built programs). So a side-effect of this
+@code{hello_SOURCES} declaration is that @file{main.c} will be
+part of the tarball created by @code{make dist}.
+
+Finally here are some explanations regarding the top-level
+@file{Makefile.am}.
+
+@example
+SUBDIRS = src
+dist_doc_DATA = README
+@end example
+
+@code{SUBDIRS} is a special variable listing all directories that
+@command{make} should recurse into before processing the current
+directory. So this line is responsible for @command{make} building
+@file{src/hello} even though we run it from the top-level. This line
+also causes @code{make install} to install @file{src/hello} before
+installing @file{README} (not that this order matters).
+
+The line @code{dist_doc_DATA = README} causes @file{README} to be
+distributed and installed in @var{docdir}. Files listed with the
+@code{_DATA} primary are not automatically part of the tarball built
+with @code{make dist}, so we add the @code{dist_} prefix so they get
+distributed. However, for @file{README} it would not have been
+necessary: @command{automake} automatically distributes any
+@file{README} file it encounters (the list of other files
+automatically distributed is presented by @code{automake --help}).
+The only important effect of this second line is therefore to install
+@file{README} during @code{make install}.
+
+One thing not covered in this example is accessing the installation
+directory values (@pxref{Standard Directory Variables}) from your
+program code, that is, converting them into defined macros. For this,
+@pxref{Defining Directories,,, autoconf, The Autoconf Manual}.

+
+
+@node General Operation
+@section General Operation
+
+Automake works by reading a @file{Makefile.am} and generating a
+@file{Makefile.in}. Certain variables and rules defined in the
+@file{Makefile.am} instruct Automake to generate more specialized code;
+for instance, a @code{bin_PROGRAMS} variable definition will cause rules
+for compiling and linking programs to be generated.
+
+@cindex Non-standard targets
+@cindex @code{git-dist}, non-standard example
+@trindex git-dist
+
+The variable definitions and rules in the @file{Makefile.am} are
+copied mostly verbatim into the generated file, with all variable
+definitions preceding all rules. This allows you to add almost
+arbitrary code into the generated @file{Makefile.in}. For instance,
+the Automake distribution includes a non-standard rule for the
+@code{git-dist} target, which the Automake maintainer uses to make
+distributions from the source control system.
+
+@cindex GNU make extensions
+
+Note that most GNU make extensions are not recognized by Automake. Using
+such extensions in a @file{Makefile.am} will lead to errors or confusing
+behavior.
+
+@cindex Append operator
+@cmindex +=
+A special exception is that the GNU make append operator, @samp{+=}, is
+supported. This operator appends its right hand argument to the variable
+specified on the left. Automake will translate the operator into
+an ordinary @samp{=} operator; @samp{+=} will thus work with any make program.
+
+Automake tries to keep comments grouped with any adjoining rules or
+variable definitions.
+
+@cindex Limitations of automake parser
+@cindex Automake parser, limitations of
+@cindex indentation in Makefile.am
+Generally, Automake is not particularly smart in the parsing of unusual
+Makefile constructs, so you're advised to avoid fancy constructs or
+``creative'' use of whitespaces.
+@c Keep this in sync with doc-parsing-buglets-tabs.sh
+For example, @key{TAB} characters cannot be used between a target name
+and the following ``@code{:}'' character, and variable assignments
+shouldn't be indented with @key{TAB} characters.
+@c Keep this in sync with doc-parsing-buglets-colneq-subst.sh
+Also, using more complex macro in target names can cause trouble:
+
+@example
+% @kbd{cat Makefile.am}
+$(FOO:=x): bar
+% @kbd{automake}
+Makefile.am:1: bad characters in variable name `$(FOO'
+Makefile.am:1: `:='-style assignments are not portable
+@end example
+
+@cindex Make targets, overriding
+@cindex Make rules, overriding
+@cindex Overriding make rules
+@cindex Overriding make targets
+
+A rule defined in @file{Makefile.am} generally overrides any such
+rule of a similar name that would be automatically generated by
+@command{automake}. Although this is a supported feature, it is generally
+best to avoid making use of it, as sometimes the generated rules are
+very particular.
+
+@cindex Variables, overriding
+@cindex Overriding make variables
+
+Similarly, a variable defined in @file{Makefile.am} or
+@code{AC_SUBST}ed from @file{configure.ac} will override any
+definition of the variable that @command{automake} would ordinarily
+create. This feature is more often useful than the ability to
+override a rule. Be warned that many of the variables generated by
+@command{automake} are considered to be for internal use only, and their
+names might change in future releases.
+
+@cindex Recursive operation of Automake
+@cindex Automake, recursive operation
+@cindex Example of recursive operation
+
+When examining a variable definition, Automake will recursively examine
+variables referenced in the definition. For example, if Automake is
+looking at the content of @code{foo_SOURCES} in this snippet
+
+@c Keep in sync with interp.sh
+@example
+xs = a.c b.c
+foo_SOURCES = c.c $(xs)
+@end example
+
+it would use the files @file{a.c}, @file{b.c}, and @file{c.c} as the
+contents of @code{foo_SOURCES}.
+
+@cindex @code{##} (special Automake comment)
+@cindex Special Automake comment
+@cindex Comment, special to Automake
+
+Automake also allows a form of comment that is @emph{not} copied into
+the output; all lines beginning with @samp{##} (leading spaces allowed)
+are completely ignored by Automake.
+
+It is customary to make the first line of @file{Makefile.am} read:
+
+@cindex Makefile.am, first line
+@cindex First line of Makefile.am
+
+@example
+## Process this file with automake to produce Makefile.in
+@end example
+
+@c FIXME discuss putting a copyright into Makefile.am here? I would but
+@c I don't know quite what to say.
+
+@c FIXME document customary ordering of Makefile.am here!
+
+
+@node Strictness
+@section Strictness
+
+@cindex Non-GNU packages
+
+While Automake is intended to be used by maintainers of GNU packages, it
+does make some effort to accommodate those who wish to use it, but do
+not want to use all the GNU conventions.
+
+@cindex Strictness, defined
+@cindex Strictness, @option{foreign}
+@cindex @option{foreign} strictness
+@cindex Strictness, @option{gnu}
+@cindex @option{gnu} strictness
+@cindex Strictness, @option{gnits}
+@cindex @option{gnits} strictness
+
+To this end, Automake supports three levels of @dfn{strictness}---the
+strictness indicating how stringently Automake should check standards
+conformance.
+
+The valid strictness levels are:
+
+@table @option
+@item foreign
+Automake will check for only those things that are absolutely
+required for proper operations. For instance, whereas GNU standards
+dictate the existence of a @file{NEWS} file, it will not be required in
+this mode. This strictness will also turn off some warnings by default
+(among them, portability warnings).
+The name comes from the fact that Automake is intended to be
+used for GNU programs; these relaxed rules are not the standard mode of
+operation.
+
+@item gnu
+Automake will check---as much as possible---for compliance to the GNU
+standards for packages. This is the default.
+
+@item gnits
+Automake will check for compliance to the as-yet-unwritten @dfn{Gnits
+standards}. These are based on the GNU standards, but are even more
+detailed. Unless you are a Gnits standards contributor, it is
+recommended that you avoid this option until such time as the Gnits
+standard is actually published (which may never happen).
+@end table
+
+@xref{Gnits}, for more information on the precise implications of the
+strictness level.
+
+Automake also has a special (and @emph{today deprecated}) ``cygnus'' mode
+that is similar to strictness but handled differently. This mode is
+useful for packages that are put into a ``Cygnus'' style tree (e.g., older
+versions of the GCC and gdb trees). @xref{Cygnus}, for more information
+on this mode. Please note that this mode @emph{is deprecated and will be
+removed in the next major Automake release (1.13)}; you must avoid its use
+in new packages, and should stop using it in existing packages as well.
+
+
+@node Uniform
+@section The Uniform Naming Scheme
+
+@cindex Uniform naming scheme
+
+Automake variables generally follow a @dfn{uniform naming scheme} that
+makes it easy to decide how programs (and other derived objects) are
+built, and how they are installed. This scheme also supports
+@command{configure} time determination of what should be built.
+
+@cindex @code{_PROGRAMS} primary variable
+@cindex @code{PROGRAMS} primary variable
+@cindex Primary variable, @code{PROGRAMS}
+@cindex Primary variable, defined
+@vindex _PROGRAMS
+
+At @command{make} time, certain variables are used to determine which
+objects are to be built. The variable names are made of several pieces
+that are concatenated together.
+
+The piece that tells @command{automake} what is being built is commonly called
+the @dfn{primary}. For instance, the primary @code{PROGRAMS} holds a
+list of programs that are to be compiled and linked.
+@vindex PROGRAMS
+
+@cindex @code{pkgdatadir}, defined
+@cindex @code{pkgincludedir}, defined
+@cindex @code{pkglibdir}, defined
+@cindex @code{pkglibexecdir}, defined
+
+@vindex pkgdatadir
+@vindex pkgincludedir
+@vindex pkglibdir
+@vindex pkglibexecdir
+
+@cindex @code{PACKAGE}, directory
+A different set of names is used to decide where the built objects
+should be installed. These names are prefixes to the primary, and they
+indicate which standard directory should be used as the installation
+directory. The standard directory names are given in the GNU standards
+(@pxref{Directory Variables, , , standards, The GNU Coding Standards}).
+Automake extends this list with @code{pkgdatadir}, @code{pkgincludedir},
+@code{pkglibdir}, and @code{pkglibexecdir}; these are the same as the
+non-@samp{pkg} versions, but with @samp{$(PACKAGE)} appended. For instance,
+@code{pkglibdir} is defined as @samp{$(libdir)/$(PACKAGE)}.
+
+@cindex @code{EXTRA_}, prepending
+For each primary, there is one additional variable named by prepending
+@samp{EXTRA_} to the primary name. This variable is used to list
+objects that may or may not be built, depending on what
+@command{configure} decides. This variable is required because Automake
+must statically know the entire list of objects that may be built in
+order to generate a @file{Makefile.in} that will work in all cases.
+
+@cindex @code{EXTRA_PROGRAMS}, defined
+@cindex Example, @code{EXTRA_PROGRAMS}
+@cindex @command{cpio} example
+
+For instance, @command{cpio} decides at configure time which programs
+should be built. Some of the programs are installed in @code{bindir},
+and some are installed in @code{sbindir}:
+
+@example
+EXTRA_PROGRAMS = mt rmt
+bin_PROGRAMS = cpio pax
+sbin_PROGRAMS = $(MORE_PROGRAMS)
+@end example
+
+Defining a primary without a prefix as a variable, e.g.,
+@samp{PROGRAMS}, is an error.
+
+Note that the common @samp{dir} suffix is left off when constructing the
+variable names; thus one writes @samp{bin_PROGRAMS} and not
+@samp{bindir_PROGRAMS}.
+
+Not every sort of object can be installed in every directory. Automake
+will flag those attempts it finds in error (but see below how to override
+the check if you really need to).
+Automake will also diagnose obvious misspellings in directory names.
+
+@cindex Extending list of installation directories
+@cindex Installation directories, extending list
+
+Sometimes the standard directories---even as augmented by
+Automake---are not enough. In particular it is sometimes useful, for
+clarity, to install objects in a subdirectory of some predefined
+directory. To this end, Automake allows you to extend the list of
+possible installation directories. A given prefix (e.g., @samp{zar})
+is valid if a variable of the same name with @samp{dir} appended is
+defined (e.g., @samp{zardir}).
+
+For instance, the following snippet will install @file{file.xml} into
+@samp{$(datadir)/xml}.
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+xmldir = $(datadir)/xml
+xml_DATA = file.xml
+@end example
+
+This feature can also be used to override the sanity checks Automake
+performs to diagnose suspicious directory/primary couples (in the
+unlikely case these checks are undesirable, and you really know what
+you're doing). For example, Automake would error out on this input:
+
+@c Should be tested in primary-prefix-invalid-couples.sh
+@example
+# Forbidden directory combinations, automake will error out on this.
+pkglib_PROGRAMS = foo
+doc_LIBRARIES = libquux.a
+@end example
+
+@noindent
+but it will succeed with this:
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+# Work around forbidden directory combinations. Do not use this
+# without a very good reason!
+my_execbindir = $(pkglibdir)
+my_doclibdir = $(docdir)
+my_execbin_PROGRAMS = foo
+my_doclib_LIBRARIES = libquux.a
+@end example
+
+The @samp{exec} substring of the @samp{my_execbindir} variable lets
+the files be installed at the right time (@pxref{The Two Parts of
+Install}).
+
+@cindex @samp{noinst_} primary prefix, definition
+@vindex noinst_
+
+The special prefix @samp{noinst_} indicates that the objects in question
+should be built but not installed at all. This is usually used for
+objects required to build the rest of your package, for instance static
+libraries (@pxref{A Library}), or helper scripts.
+
+@cindex @samp{check_} primary prefix, definition
+@vindex check_
+
+The special prefix @samp{check_} indicates that the objects in question
+should not be built until the @samp{make check} command is run. Those
+objects are not installed either.
+
+The current primary names are @samp{PROGRAMS}, @samp{LIBRARIES},
+@samp{LTLIBRARIES}, @samp{LISP}, @samp{PYTHON}, @samp{JAVA},
+@samp{SCRIPTS}, @samp{DATA}, @samp{HEADERS}, @samp{MANS}, and
+@samp{TEXINFOS}.
+@vindex PROGRAMS
+@vindex LIBRARIES
+@vindex LTLIBRARIES
+@vindex LISP
+@vindex PYTHON
+@vindex JAVA
+@vindex SCRIPTS
+@vindex DATA
+@vindex HEADERS
+@vindex MANS
+@vindex TEXINFOS
+
+Some primaries also allow additional prefixes that control other
+aspects of @command{automake}'s behavior. The currently defined prefixes
+are @samp{dist_}, @samp{nodist_}, @samp{nobase_}, and @samp{notrans_}.
+These prefixes are explained later (@pxref{Program and Library Variables})
+(@pxref{Man Pages}).
+
+
+@node Length Limitations
+@section Staying below the command line length limit
+
+@cindex command line length limit
+@cindex ARG_MAX
+
+Traditionally, most unix-like systems have a length limitation for the
+command line arguments and environment contents when creating new
+processes (see for example
+@uref{http://www.in-ulm.de/@/~mascheck/@/various/@/argmax/} for an
+overview on this issue),
+which of course also applies to commands spawned by @command{make}.
+POSIX requires this limit to be at least 4096 bytes, and most modern
+systems have quite high limits (or are unlimited).
+
+In order to create portable Makefiles that do not trip over these
+limits, it is necessary to keep the length of file lists bounded.
+Unfortunately, it is not possible to do so fully transparently within
+Automake, so your help may be needed. Typically, you can split long
+file lists manually and use different installation directory names for
+each list. For example,
+
+@example
+data_DATA = file1 @dots{} file@var{N} file@var{N+1} @dots{} file@var{2N}
+@end example
+
+@noindent
+may also be written as
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+data_DATA = file1 @dots{} file@var{N}
+data2dir = $(datadir)
+data2_DATA = file@var{N+1} @dots{} file@var{2N}
+@end example
+
+@noindent
+and will cause Automake to treat the two lists separately during
+@code{make install}. See @ref{The Two Parts of Install} for choosing
+directory names that will keep the ordering of the two parts of
+installation Note that @code{make dist} may still only work on a host
+with a higher length limit in this example.
+
+Automake itself employs a couple of strategies to avoid long command
+lines. For example, when @samp{$@{srcdir@}/} is prepended to file
+names, as can happen with above @code{$(data_DATA)} lists, it limits
+the amount of arguments passed to external commands.
+
+Unfortunately, some system's @command{make} commands may prepend
+@code{VPATH} prefixes like @samp{$@{srcdir@}/} to file names from the
+source tree automatically (@pxref{Automatic Rule Rewriting, , Automatic
+Rule Rewriting, autoconf, The Autoconf Manual}). In this case, the user
+may have to switch to use GNU Make, or refrain from using VPATH builds,
+in order to stay below the length limit.
+
+For libraries and programs built from many sources, convenience archives
+may be used as intermediates in order to limit the object list length
+(@pxref{Libtool Convenience Libraries}).
+
+
+@node Canonicalization
+@section How derived variables are named
+
+@cindex canonicalizing Automake variables
+
+Sometimes a Makefile variable name is derived from some text the
+maintainer supplies. For instance, a program name listed in
+@samp{_PROGRAMS} is rewritten into the name of a @samp{_SOURCES}
+variable. In cases like this, Automake canonicalizes the text, so that
+program names and the like do not have to follow Makefile variable naming
+rules. All characters in the name except for letters, numbers, the
+strudel (@@), and the underscore are turned into underscores when making
+variable references.
+
+For example, if your program is named @file{sniff-glue}, the derived
+variable name would be @samp{sniff_glue_SOURCES}, not
+@samp{sniff-glue_SOURCES}. Similarly the sources for a library named
+@file{libmumble++.a} should be listed in the
+@samp{libmumble___a_SOURCES} variable.
+
+The strudel is an addition, to make the use of Autoconf substitutions in
+variable names less obfuscating.
+
+
+@node User Variables
+@section Variables reserved for the user
+
+@cindex variables, reserved for the user
+@cindex user variables
+
+Some @file{Makefile} variables are reserved by the GNU Coding Standards
+for the use of the ``user''---the person building the package. For
+instance, @code{CFLAGS} is one such variable.
+
+Sometimes package developers are tempted to set user variables such as
+@code{CFLAGS} because it appears to make their job easier. However,
+the package itself should never set a user variable, particularly not
+to include switches that are required for proper compilation of the
+package. Since these variables are documented as being for the
+package builder, that person rightfully expects to be able to override
+any of these variables at build time.
+
+To get around this problem, Automake introduces an automake-specific
+shadow variable for each user flag variable. (Shadow variables are
+not introduced for variables like @code{CC}, where they would make no
+sense.) The shadow variable is named by prepending @samp{AM_} to the
+user variable's name. For instance, the shadow variable for
+@code{YFLAGS} is @code{AM_YFLAGS}. The package maintainer---that is,
+the author(s) of the @file{Makefile.am} and @file{configure.ac}
+files---may adjust these shadow variables however necessary.
+
+@xref{Flag Variables Ordering}, for more discussion about these
+variables and how they interact with per-target variables.
+
+@node Auxiliary Programs
+@section Programs automake might require
+
+@cindex Programs, auxiliary
+@cindex Auxiliary programs
+
+Automake sometimes requires helper programs so that the generated
+@file{Makefile} can do its work properly. There are a fairly large
+number of them, and we list them here.
+
+Although all of these files are distributed and installed with
+Automake, a couple of them are maintained separately. The Automake
+copies are updated before each release, but we mention the original
+source in case you need more recent versions.
+
+@table @code
+@item ar-lib
+This is a wrapper primarily for the Microsoft lib archiver, to make
+it more POSIX-like.
+
+@item compile
+This is a wrapper for compilers that do not accept options @option{-c}
+and @option{-o} at the same time. It is only used when absolutely
+required. Such compilers are rare, with the Microsoft C/C++ Compiler
+as the most notable exception. This wrapper also makes the following
+common options available for that compiler, while performing file name
+translation where needed: @option{-I}, @option{-L}, @option{-l},
+@option{-Wl,} and @option{-Xlinker}.
+
+@item config.guess
+@itemx config.sub
+These two programs compute the canonical triplets for the given build,
+host, or target architecture. These programs are updated regularly to
+support new architectures and fix probes broken by changes in new
+kernel versions. Each new release of Automake comes with up-to-date
+copies of these programs. If your copy of Automake is getting old,
+you are encouraged to fetch the latest versions of these files from
+@url{http://savannah.gnu.org/git/?group=config} before making a
+release.
+
+@item depcomp
+This program understands how to run a compiler so that it will
+generate not only the desired output but also dependency information
+that is then used by the automatic dependency tracking feature
+(@pxref{Dependencies}).
+
+@item elisp-comp
+This program is used to byte-compile Emacs Lisp code.
+
+@item install-sh
+This is a replacement for the @command{install} program that works on
+platforms where @command{install} is unavailable or unusable.
+
+@item mdate-sh
+This script is used to generate a @file{version.texi} file. It examines
+a file and prints some date information about it.
+
+@item missing
+This wraps a number of programs that are typically only required by
+maintainers. If the program in question doesn't exist,
+@command{missing} prints an informative warning and attempts to fix
+things so that the build can continue.
+
+@item mkinstalldirs
+This script used to be a wrapper around @samp{mkdir -p}, which is not
+portable. Now we prefer to use @samp{install-sh -d} when @command{configure}
+finds that @samp{mkdir -p} does not work, this makes one less script to
+distribute.
+
+For backward compatibility @file{mkinstalldirs} is still used and
+distributed when @command{automake} finds it in a package. But it is no
+longer installed automatically, and it should be safe to remove it.
+
+@item py-compile
+This is used to byte-compile Python scripts.
+
+@item test-driver
+This implements the default test driver offered by the parallel
+testsuite harness.
+
+@item texinfo.tex
+Not a program, this file is required for @samp{make dvi}, @samp{make
+ps} and @samp{make pdf} to work when Texinfo sources are in the
+package. The latest version can be downloaded from
+@url{http://www.gnu.org/software/texinfo/}.
+
+@item ylwrap
+This program wraps @command{lex} and @command{yacc} to rename their
+output files. It also ensures that, for instance, multiple
+@command{yacc} instances can be invoked in a single directory in
+parallel.

+@node Examples
+@chapter Some example packages
+
+This section contains two small examples.
+
+The first example (@pxref{Complete}) assumes you have an existing
+project already using Autoconf, with handcrafted @file{Makefile}s, and
+that you want to convert it to using Automake. If you are discovering
+both tools, it is probably better that you look at the Hello World
+example presented earlier (@pxref{Hello World}).
+
+The second example (@pxref{true}) shows how two programs can be built
+from the same file, using different compilation parameters. It
+contains some technical digressions that are probably best skipped on
+first read.

+@node Complete
+@section A simple example, start to finish
+
+@cindex Complete example
+
+Let's suppose you just finished writing @code{zardoz}, a program to make
+your head float from vortex to vortex. You've been using Autoconf to
+provide a portability framework, but your @file{Makefile.in}s have been
+ad-hoc. You want to make them bulletproof, so you turn to Automake.
+
+@cindex @code{AM_INIT_AUTOMAKE}, example use
+
+The first step is to update your @file{configure.ac} to include the
+commands that @command{automake} needs. The way to do this is to add an
+@code{AM_INIT_AUTOMAKE} call just after @code{AC_INIT}:
+
+@example
+AC_INIT([zardoz], [1.0])
+AM_INIT_AUTOMAKE
+@dots{}
+@end example
+
+Since your program doesn't have any complicating factors (e.g., it
+doesn't use @code{gettext}, it doesn't want to build a shared library),
+you're done with this part. That was easy!
+
+@cindex @command{aclocal} program, introduction
+@cindex @file{aclocal.m4}, preexisting
+@cindex @file{acinclude.m4}, defined
+
+Now you must regenerate @file{configure}. But to do that, you'll need
+to tell @command{autoconf} how to find the new macro you've used. The
+easiest way to do this is to use the @command{aclocal} program to
+generate your @file{aclocal.m4} for you. But wait@dots{} maybe you
+already have an @file{aclocal.m4}, because you had to write some hairy
+macros for your program. The @command{aclocal} program lets you put
+your own macros into @file{acinclude.m4}, so simply rename and then
+run:
+
+@example
+mv aclocal.m4 acinclude.m4
+aclocal
+autoconf
+@end example
+
+@cindex @command{zardoz} example
+
+Now it is time to write your @file{Makefile.am} for @code{zardoz}.
+Since @code{zardoz} is a user program, you want to install it where the
+rest of the user programs go: @code{bindir}. Additionally,
+@code{zardoz} has some Texinfo documentation. Your @file{configure.ac}
+script uses @code{AC_REPLACE_FUNCS}, so you need to link against
+@samp{$(LIBOBJS)}. So here's what you'd write:
+
+@example
+bin_PROGRAMS = zardoz
+zardoz_SOURCES = main.c head.c float.c vortex9.c gun.c
+zardoz_LDADD = $(LIBOBJS)
+
+info_TEXINFOS = zardoz.texi
+@end example
+
+Now you can run @samp{automake --add-missing} to generate your
+@file{Makefile.in} and grab any auxiliary files you might need, and
+you're done!

+@node true
+@section Building true and false
+
+@cindex Example, @command{false} and @command{true}
+@cindex @command{false} Example
+@cindex @command{true} Example
+
+Here is another, trickier example. It shows how to generate two
+programs (@code{true} and @code{false}) from the same source file
+(@file{true.c}). The difficult part is that each compilation of
+@file{true.c} requires different @code{cpp} flags.
+
+@example
+bin_PROGRAMS = true false
+false_SOURCES =
+false_LDADD = false.o
+
+true.o: true.c
+ $(COMPILE) -DEXIT_CODE=0 -c true.c
+
+false.o: true.c
+ $(COMPILE) -DEXIT_CODE=1 -o false.o -c true.c
+@end example
+
+Note that there is no @code{true_SOURCES} definition. Automake will
+implicitly assume that there is a source file named @file{true.c}
+(@pxref{Default _SOURCES}), and
+define rules to compile @file{true.o} and link @file{true}. The
+@samp{true.o: true.c} rule supplied by the above @file{Makefile.am},
+will override the Automake generated rule to build @file{true.o}.
+
+@code{false_SOURCES} is defined to be empty---that way no implicit value
+is substituted. Because we have not listed the source of
+@file{false}, we have to tell Automake how to link the program. This is
+the purpose of the @code{false_LDADD} line. A @code{false_DEPENDENCIES}
+variable, holding the dependencies of the @file{false} target will be
+automatically generated by Automake from the content of
+@code{false_LDADD}.
+
+The above rules won't work if your compiler doesn't accept both
+@option{-c} and @option{-o}. The simplest fix for this is to introduce a
+bogus dependency (to avoid problems with a parallel @command{make}):
+
+@example
+true.o: true.c false.o
+ $(COMPILE) -DEXIT_CODE=0 -c true.c
+
+false.o: true.c
+ $(COMPILE) -DEXIT_CODE=1 -c true.c && mv true.o false.o
+@end example
+
+As it turns out, there is also a much easier way to do this same task.
+Some of the above technique is useful enough that we've kept the
+example in the manual. However if you were to build @code{true} and
+@code{false} in real life, you would probably use per-program
+compilation flags, like so:
+
+@c Keep in sync with specflg7.sh and specflg8.sh
+@example
+bin_PROGRAMS = false true
+
+false_SOURCES = true.c
+false_CPPFLAGS = -DEXIT_CODE=1
+
+true_SOURCES = true.c
+true_CPPFLAGS = -DEXIT_CODE=0
+@end example
+
+In this case Automake will cause @file{true.c} to be compiled twice,
+with different flags. In this instance, the names of the object files
+would be chosen by automake; they would be @file{false-true.o} and
+@file{true-true.o}. (The name of the object files rarely matters.)

+@cindex Invoking @command{automake}
+@cindex @command{automake}, invoking
+@cindex Invocation of @command{automake}
+@cindex @command{automake}, invocation
+
+To create all the @file{Makefile.in}s for a package, run the
+@command{automake} program in the top level directory, with no
+arguments. @command{automake} will automatically find each
+appropriate @file{Makefile.am} (by scanning @file{configure.ac};
+@pxref{configure}) and generate the corresponding @file{Makefile.in}.
+Note that @command{automake} has a rather simplistic view of what
+constitutes a package; it assumes that a package has only one
+@file{configure.ac}, at the top. If your package has multiple
+@file{configure.ac}s, then you must run @command{automake} in each
+directory holding a @file{configure.ac}. (Alternatively, you may rely
+on Autoconf's @command{autoreconf}, which is able to recurse your
+package tree and run @command{automake} where appropriate.)
+
+You can optionally give @command{automake} an argument; @file{.am} is
+appended to the argument and the result is used as the name of the
+input file. This feature is generally only used to automatically
+rebuild an out-of-date @file{Makefile.in}. Note that
+@command{automake} must always be run from the topmost directory of a
+project, even if being used to regenerate the @file{Makefile.in} in
+some subdirectory. This is necessary because @command{automake} must
+scan @file{configure.ac}, and because @command{automake} uses the
+knowledge that a @file{Makefile.in} is in a subdirectory to change its
+behavior in some cases.
+
+@vindex AUTOCONF
+Automake will run @command{autoconf} to scan @file{configure.ac} and
+its dependencies (i.e., @file{aclocal.m4} and any included file),
+therefore @command{autoconf} must be in your @env{PATH}. If there is
+an @env{AUTOCONF} variable in your environment it will be used
+instead of @command{autoconf}, this allows you to select a particular
+version of Autoconf. By the way, don't misunderstand this paragraph:
+@command{automake} runs @command{autoconf} to @strong{scan} your
+@file{configure.ac}, this won't build @file{configure} and you still
+have to run @command{autoconf} yourself for this purpose.
+
+@cindex @command{automake} options
+@cindex Options, @command{automake}
+@cindex Strictness, command line
+
+@command{automake} accepts the following options:
+
+@cindex Extra files distributed with Automake
+@cindex Files distributed with Automake
+@cindex @file{config.guess}
+
+@table @code
+@item -a
+@itemx --add-missing
+@opindex -a
+@opindex --add-missing
+Automake requires certain common files to exist in certain situations;
+for instance, @file{config.guess} is required if @file{configure.ac} invokes
+@code{AC_CANONICAL_HOST}. Automake is distributed with several of these
+files (@pxref{Auxiliary Programs}); this option will cause the missing
+ones to be automatically added to the package, whenever possible. In
+general if Automake tells you a file is missing, try using this option.
+By default Automake tries to make a symbolic link pointing to its own
+copy of the missing file; this can be changed with @option{--copy}.
+
+Many of the potentially-missing files are common scripts whose
+location may be specified via the @code{AC_CONFIG_AUX_DIR} macro.
+Therefore, @code{AC_CONFIG_AUX_DIR}'s setting affects whether a
+file is considered missing, and where the missing file is added
+(@pxref{Optional}).
+
+In some strictness modes, additional files are installed, see @ref{Gnits}
+for more information.
+
+@item --libdir=@var{dir}
+@opindex --libdir
+Look for Automake data files in directory @var{dir} instead of in the
+installation directory. This is typically used for debugging.
+
+@item --print-libdir
+@opindex --print-libdir
+Print the path of the installation directory containing Automake-provided
+scripts and data files (like e.g., @file{texinfo.texi} and
+@file{install-sh}).
+
+@item -c
+@opindex -c
+@itemx --copy
+@opindex --copy
+When used with @option{--add-missing}, causes installed files to be
+copied. The default is to make a symbolic link.
+
+@item --cygnus
+@opindex --cygnus
+Causes the generated @file{Makefile.in}s to follow Cygnus rules, instead
+of GNU or Gnits rules. For more information, see @ref{Cygnus}.
+Note that @emph{this mode of operation is deprecated, and will be removed}
+in the next major Automake release (1.13).
+
+@item -f
+@opindex -f
+@itemx --force-missing
+@opindex --force-missing
+When used with @option{--add-missing}, causes standard files to be reinstalled
+even if they already exist in the source tree. This involves removing
+the file from the source tree before creating the new symlink (or, with
+@option{--copy}, copying the new file).
+
+@item --foreign
+@opindex --foreign
+Set the global strictness to @option{foreign}. For more information, see
+@ref{Strictness}.
+
+@item --gnits
+@opindex --gnits
+Set the global strictness to @option{gnits}. For more information, see
+@ref{Gnits}.
+
+@item --gnu
+@opindex --gnu
+Set the global strictness to @option{gnu}. For more information, see
+@ref{Gnits}. This is the default strictness.
+
+@item --help
+@opindex --help
+Print a summary of the command line options and exit.
+
+@item -i
+@itemx --ignore-deps
+@opindex -i
+This disables the dependency tracking feature in generated
+@file{Makefile}s; see @ref{Dependencies}.
+
+@item --include-deps
+@opindex --include-deps
+This enables the dependency tracking feature. This feature is enabled
+by default. This option is provided for historical reasons only and
+probably should not be used.
+
+@item --no-force
+@opindex --no-force
+Ordinarily @command{automake} creates all @file{Makefile.in}s mentioned in
+@file{configure.ac}. This option causes it to only update those
+@file{Makefile.in}s that are out of date with respect to one of their
+dependents.
+
+@item -o @var{dir}
+@itemx --output-dir=@var{dir}
+@opindex -o
+@opindex --output-dir
+Put the generated @file{Makefile.in} in the directory @var{dir}.
+Ordinarily each @file{Makefile.in} is created in the directory of the
+corresponding @file{Makefile.am}. This option is deprecated and will be
+removed in a future release.
+
+@item -v
+@itemx --verbose
+@opindex -v
+@opindex --verbose
+Cause Automake to print information about which files are being read or
+created.
+
+@item --version
+@opindex --version
+Print the version number of Automake and exit.
+
+@item -W CATEGORY
+@itemx --warnings=@var{category}
+@opindex -W
+@opindex --warnings
+Output warnings falling in @var{category}. @var{category} can be

+@end table
+
+A category can be turned off by prefixing its name with @samp{no-}. For
+instance, @option{-Wno-syntax} will hide the warnings about unused
+variables.
+
+The categories output by default are @samp{syntax} and
+@samp{unsupported}. Additionally, @samp{gnu} and @samp{portability}
+are enabled in @option{--gnu} and @option{--gnits} strictness.
+On the other hand, the @option{silent-rules} options (@pxref{Options})
+turns off portability warnings about recursive variable expansions.
+
+@c Checked by extra-portability.sh
+Turning off @samp{portability} will also turn off @samp{extra-portability},
+and similarly turning on @samp{extra-portability} will also turn on
+@samp{portability}. However, turning on @samp{portability} or turning
+off @samp{extra-portability} will not affect the other category.
+
+@vindex WARNINGS
+The environment variable @env{WARNINGS} can contain a comma separated
+list of categories to enable. It will be taken into account before the
+command-line switches, this way @option{-Wnone} will also ignore any
+warning category enabled by @env{WARNINGS}. This variable is also used
+by other tools like @command{autoconf}; unknown categories are ignored
+for this reason.

+@cindex Automake requirements
+@cindex Requirements of Automake
+
+@acindex AM_INIT_AUTOMAKE
+The one real requirement of Automake is that your @file{configure.ac}
+call @code{AM_INIT_AUTOMAKE}. This macro does several things that are
+required for proper Automake operation (@pxref{Macros}).
+
+Here are the other macros that Automake requires but which are not run
+by @code{AM_INIT_AUTOMAKE}:
+
+@table @code
+@item AC_CONFIG_FILES
+@itemx AC_OUTPUT
+@acindex AC_CONFIG_FILES
+@acindex AC_OUTPUT
+These two macros are usually invoked as follows near the end of
+@file{configure.ac}.
+
+@example
+@dots{}
+AC_CONFIG_FILES([
+ Makefile
+ doc/Makefile
+ src/Makefile
+ src/lib/Makefile
+ @dots{}
+])
+AC_OUTPUT
+@end example
+
+Automake uses these to determine which files to create (@pxref{Output, ,
+Creating Output Files, autoconf, The Autoconf Manual}). A listed file
+is considered to be an Automake generated @file{Makefile} if there
+exists a file with the same name and the @file{.am} extension appended.
+Typically, @samp{AC_CONFIG_FILES([foo/Makefile])} will cause Automake to
+generate @file{foo/Makefile.in} if @file{foo/Makefile.am} exists.
+
+When using @code{AC_CONFIG_FILES} with multiple input files, as in
+
+@example
+AC_CONFIG_FILES([Makefile:top.in:Makefile.in:bot.in])
+@end example
+
+@noindent
+@command{automake} will generate the first @file{.in} input file for
+which a @file{.am} file exists. If no such file exists the output
+file is not considered to be generated by Automake.
+
+Files created by @code{AC_CONFIG_FILES}, be they Automake
+@file{Makefile}s or not, are all removed by @samp{make distclean}.
+Their inputs are automatically distributed, unless they
+are the output of prior @code{AC_CONFIG_FILES} commands.
+Finally, rebuild rules are generated in the Automake @file{Makefile}
+existing in the subdirectory of the output file, if there is one, or
+in the top-level @file{Makefile} otherwise.
+
+The above machinery (cleaning, distributing, and rebuilding) works
+fine if the @code{AC_CONFIG_FILES} specifications contain only
+literals. If part of the specification uses shell variables,
+@command{automake} will not be able to fulfill this setup, and you will
+have to complete the missing bits by hand. For instance, on
+
+@c Keep in sync with output11.sh
+@example
+file=input
+@dots{}
+AC_CONFIG_FILES([output:$file],, [file=$file])
+@end example
+
+@noindent
+@command{automake} will output rules to clean @file{output}, and
+rebuild it. However the rebuild rule will not depend on @file{input},
+and this file will not be distributed either. (You must add
+@samp{EXTRA_DIST = input} to your @file{Makefile.am} if @file{input} is a
+source file.)
+
+Similarly
+
+@c Keep in sync with output11.sh
+@example
+file=output
+file2=out:in
+@dots{}
+AC_CONFIG_FILES([$file:input],, [file=$file])
+AC_CONFIG_FILES([$file2],, [file2=$file2])
+@end example
+
+@noindent
+will only cause @file{input} to be distributed. No file will be
+cleaned automatically (add @samp{DISTCLEANFILES = output out}
+yourself), and no rebuild rule will be output.
+
+Obviously @command{automake} cannot guess what value @samp{$file} is
+going to hold later when @file{configure} is run, and it cannot use
+the shell variable @samp{$file} in a @file{Makefile}. However, if you
+make reference to @samp{$file} as @samp{$@{file@}} (i.e., in a way
+that is compatible with @command{make}'s syntax) and furthermore use
+@code{AC_SUBST} to ensure that @samp{$@{file@}} is meaningful in a
+@file{Makefile}, then @command{automake} will be able to use
+@samp{$@{file@}} to generate all these rules. For instance, here is
+how the Automake package itself generates versioned scripts for its
+test suite:
+
+@example
+AC_SUBST([APIVERSION], @dots{})
+@dots{}
+AC_CONFIG_FILES(
+ [tests/aclocal-$@{APIVERSION@}:tests/aclocal.in],
+ [chmod +x tests/aclocal-$@{APIVERSION@}],
+ [APIVERSION=$APIVERSION])
+AC_CONFIG_FILES(
+ [tests/automake-$@{APIVERSION@}:tests/automake.in],
+ [chmod +x tests/automake-$@{APIVERSION@}])
+@end example
+
+@noindent
+Here cleaning, distributing, and rebuilding are done automatically,
+because @samp{$@{APIVERSION@}} is known at @command{make}-time.
+
+Note that you should not use shell variables to declare
+@file{Makefile} files for which @command{automake} must create
+@file{Makefile.in}. Even @code{AC_SUBST} does not help here, because
+@command{automake} needs to know the file name when it runs in order
+to check whether @file{Makefile.am} exists. (In the very hairy case
+that your setup requires such use of variables, you will have to tell
+Automake which @file{Makefile.in}s to generate on the command-line.)
+
+It is possible to let @command{automake} emit conditional rules for
+@code{AC_CONFIG_FILES} with the help of @code{AM_COND_IF}
+(@pxref{Optional}).
+
+To summarize:
+@itemize @bullet
+@item
+Use literals for @file{Makefile}s, and for other files whenever possible.
+@item
+Use @samp{$file} (or @samp{$@{file@}} without @samp{AC_SUBST([file])})
+for files that @command{automake} should ignore.

+@section Other things Automake recognizes
+
+@cindex Macros Automake recognizes
+@cindex Recognized macros by Automake
+
+Every time Automake is run it calls Autoconf to trace
+@file{configure.ac}. This way it can recognize the use of certain
+macros and tailor the generated @file{Makefile.in} appropriately.
+Currently recognized macros and their effects are:
+
+@ftable @code
+@item AC_CANONICAL_BUILD
+@itemx AC_CANONICAL_HOST
+@itemx AC_CANONICAL_TARGET
+@vindex build_triplet
+@vindex host_triplet
+@vindex target_triplet
+Automake will ensure that @file{config.guess} and @file{config.sub}
+exist. Also, the @file{Makefile} variables @code{build_triplet},
+@code{host_triplet} and @code{target_triplet} are introduced. See
+@ref{Canonicalizing, , Getting the Canonical System Type, autoconf,
+The Autoconf Manual}.
+
+@item AC_CONFIG_AUX_DIR
+Automake will look for various helper scripts, such as
+@file{install-sh}, in the directory named in this macro invocation.
+@c This list is accurate relative to version 1.11
+(The full list of scripts is:
+@file{ar-lib},
+@file{config.guess},
+@file{config.sub},
+@file{depcomp},
+@file{elisp-comp},
+@file{compile},
+@file{install-sh},
+@file{ltmain.sh},
+@file{mdate-sh},
+@file{missing},
+@file{mkinstalldirs},
+@file{py-compile},
+@file{test-driver},
+@file{texinfo.tex},
+@file{ylwrap}.)
+Not all scripts are always searched for; some scripts
+will only be sought if the generated @file{Makefile.in} requires them.
+
+If @code{AC_CONFIG_AUX_DIR} is not given, the scripts are looked for in
+their standard locations. For @file{mdate-sh},
+@file{texinfo.tex}, and @file{ylwrap}, the standard location is the
+source directory corresponding to the current @file{Makefile.am}. For
+the rest, the standard location is the first one of @file{.}, @file{..},
+or @file{../..} (relative to the top source directory) that provides any
+one of the helper scripts. @xref{Input, , Finding `configure' Input,
+autoconf, The Autoconf Manual}.
+
+Required files from @code{AC_CONFIG_AUX_DIR} are automatically
+distributed, even if there is no @file{Makefile.am} in this directory.
+
+@item AC_CONFIG_LIBOBJ_DIR
+Automake will require the sources file declared with
+@code{AC_LIBSOURCE} (see below) in the directory specified by this
+macro.
+
+@item AC_CONFIG_HEADERS
+Automake will generate rules to rebuild these headers. Older versions
+of Automake required the use of @code{AM_CONFIG_HEADER}
+(@pxref{Macros}); this is no longer the case.
+
+As with @code{AC_CONFIG_FILES} (@pxref{Requirements}), parts of the
+specification using shell variables will be ignored as far as
+cleaning, distributing, and rebuilding is concerned.
+
+@item AC_CONFIG_LINKS
+Automake will generate rules to remove @file{configure} generated
+links on @samp{make distclean} and to distribute named source files as
+part of @samp{make dist}.
+
+As for @code{AC_CONFIG_FILES} (@pxref{Requirements}), parts of the
+specification using shell variables will be ignored as far as cleaning
+and distributing is concerned. (There are no rebuild rules for links.)
+
+@item AC_LIBOBJ
+@itemx AC_LIBSOURCE
+@itemx AC_LIBSOURCES
+@vindex LIBOBJS
+Automake will automatically distribute any file listed in
+@code{AC_LIBSOURCE} or @code{AC_LIBSOURCES}.
+
+Note that the @code{AC_LIBOBJ} macro calls @code{AC_LIBSOURCE}. So if
+an Autoconf macro is documented to call @samp{AC_LIBOBJ([file])}, then
+@file{file.c} will be distributed automatically by Automake. This
+encompasses many macros like @code{AC_FUNC_ALLOCA},
+@code{AC_FUNC_MEMCMP}, @code{AC_REPLACE_FUNCS}, and others.
+
+By the way, direct assignments to @code{LIBOBJS} are no longer
+supported. You should always use @code{AC_LIBOBJ} for this purpose.

+above. @xref{Input, , Finding @command{configure} Input, autoconf,

+
+@item AC_SUBST
+The first argument is automatically defined as a variable in each
+generated @file{Makefile.in}, unless @code{AM_SUBST_NOTMAKE} is also
+used for this variable. @xref{Setting Output Variables, , Setting
+Output Variables, autoconf, The Autoconf Manual}.
+
+For every substituted variable @var{var}, @command{automake} will add
+a line @code{@var{var} = @var{value}} to each @file{Makefile.in} file.
+Many Autoconf macros invoke @code{AC_SUBST} to set output variables
+this way, e.g., @code{AC_PATH_XTRA} defines @code{X_CFLAGS} and
+@code{X_LIBS}. Thus, you can access these variables as
+@code{$(X_CFLAGS)} and @code{$(X_LIBS)} in any @file{Makefile.am}
+if @code{AC_PATH_XTRA} is called.
+
+@item AM_CONDITIONAL
+This introduces an Automake conditional (@pxref{Conditionals}).
+
+@item AM_COND_IF
+This macro allows @code{automake} to detect subsequent access within
+@file{configure.ac} to a conditional previously introduced with
+@code{AM_CONDITIONAL}, thus enabling conditional @code{AC_CONFIG_FILES}
+(@pxref{Usage of Conditionals}).
+
+@item AM_GNU_GETTEXT
+This macro is required for packages that use GNU gettext
+(@pxref{gettext}). It is distributed with gettext. If Automake sees
+this macro it ensures that the package meets some of gettext's
+requirements.
+
+@item AM_GNU_GETTEXT_INTL_SUBDIR
+This macro specifies that the @file{intl/} subdirectory is to be built,
+even if the @code{AM_GNU_GETTEXT} macro was invoked with a first argument
+of @samp{external}.
+
+@item AM_MAINTAINER_MODE(@ovar{default-mode})
+@opindex --enable-maintainer-mode
+@opindex --disable-maintainer-mode
+This macro adds an @option{--enable-maintainer-mode} option to
+@command{configure}. If this is used, @command{automake} will cause
+``maintainer-only'' rules to be turned off by default in the
+generated @file{Makefile.in}s, unless @var{default-mode} is
+@samp{enable}. This macro defines the @code{MAINTAINER_MODE}
+conditional, which you can use in your own @file{Makefile.am}.
+@xref{maintainer-mode}.
+
+@item AM_SUBST_NOTMAKE(@var{var})
+Prevent Automake from defining a variable @var{var}, even if it is
+substituted by @command{config.status}. Normally, Automake defines a
+@command{make} variable for each @command{configure} substitution,
+i.e., for each @code{AC_SUBST([@var{var}])}. This macro prevents that
+definition from Automake. If @code{AC_SUBST} has not been called
+for this variable, then @code{AM_SUBST_NOTMAKE} has no effects.
+Preventing variable definitions may be useful for substitution of
+multi-line values, where @code{@var{var} = @@@var{value}@@} might yield
+unintended results.
+
+@item m4_include
+Files included by @file{configure.ac} using this macro will be
+detected by Automake and automatically distributed. They will also
+appear as dependencies in @file{Makefile} rules.
+
+@code{m4_include} is seldom used by @file{configure.ac} authors, but
+can appear in @file{aclocal.m4} when @command{aclocal} detects that
+some required macros come from files local to your package (as opposed to
+macros installed in a system-wide directory, @pxref{aclocal Invocation}).

+
+Automake includes a number of Autoconf macros that can be used in
+your package (@pxref{Macros}); some of them are actually required by
+Automake in certain situations. These macros must be defined in your
+@file{aclocal.m4}; otherwise they will not be seen by
+@command{autoconf}.
+
+The @command{aclocal} program will automatically generate
+@file{aclocal.m4} files based on the contents of @file{configure.ac}.
+This provides a convenient way to get Automake-provided macros,
+without having to search around. The @command{aclocal} mechanism
+allows other packages to supply their own macros (@pxref{Extending
+aclocal}). You can also use it to maintain your own set of custom
+macros (@pxref{Local Macros}).
+
+At startup, @command{aclocal} scans all the @file{.m4} files it can
+find, looking for macro definitions (@pxref{Macro Search Path}). Then
+it scans @file{configure.ac}. Any mention of one of the macros found
+in the first step causes that macro, and any macros it in turn
+requires, to be put into @file{aclocal.m4}.
+
+@emph{Putting} the file that contains the macro definition into
+@file{aclocal.m4} is usually done by copying the entire text of this
+file, including unused macro definitions as well as both @samp{#} and
+@samp{dnl} comments. If you want to make a comment that will be
+completely ignored by @command{aclocal}, use @samp{##} as the comment
+leader.
+
+When a file selected by @command{aclocal} is located in a subdirectory
+specified as a relative search path with @command{aclocal}'s @option{-I}
+argument, @command{aclocal} assumes the file belongs to the package
+and uses @code{m4_include} instead of copying it into
+@file{aclocal.m4}. This makes the package smaller, eases dependency
+tracking, and cause the file to be distributed automatically.
+(@xref{Local Macros}, for an example.) Any macro that is found in a
+system-wide directory, or via an absolute search path will be copied.
+So use @samp{-I `pwd`/reldir} instead of @samp{-I reldir} whenever
+some relative directory should be considered outside the package.
+
+The contents of @file{acinclude.m4}, if this file exists, are also
+automatically included in @file{aclocal.m4}. We recommend against
+using @file{acinclude.m4} in new packages (@pxref{Local Macros}).
+
+@vindex AUTOM4TE
+@cindex autom4te
+While computing @file{aclocal.m4}, @command{aclocal} runs
+@command{autom4te} (@pxref{Using autom4te, , Using @command{Autom4te},
+autoconf, The Autoconf Manual}) in order to trace the macros that are
+really used, and omit from @file{aclocal.m4} all macros that are
+mentioned but otherwise unexpanded (this can happen when a macro is
+called conditionally). @command{autom4te} is expected to be in the
+@env{PATH}, just as @command{autoconf}. Its location can be
+overridden using the @env{AUTOM4TE} environment variable.

+@command{aclocal} accepts the following options:
+
+@table @code
+@item --automake-acdir=@var{dir}
+@opindex --automake-acdir
+Look for the automake-provided macro files in @var{dir} instead of

+
+@item --diff[=@var{command}]
+@opindex --diff
+Run @var{command} on M4 file that would be installed or overwritten

+Do not actually overwrite (or create) @file{aclocal.m4} and M4
+files installed by @option{--install}.
+

+
+@item --install
+@opindex --install
+Install system-wide third-party macros into the first directory

+@c Keep in sync with aclocal-install-absdir.sh
+Note that this will happen also if @var{dir} is an absolute path.
+
+@cindex serial number and @option{--install}
+When this option is used, and only when this option is used,

+that appear in macros: an M4 file is ignored if there exists another
+M4 file with the same basename and a greater serial number in the

+
+@item --force
+@opindex --force
+Always overwrite the output file. The default is to overwrite the output
+file only when really needed, i.e., when its contents changes or if one
+of its dependencies is younger.
+
+This option forces the update of @file{aclocal.m4} (or the file

+
+@end table
+
+@node Macro Search Path
+@subsection Macro Search Path
+
+@cindex Macro search path
+@cindex @command{aclocal} search path
+
+By default, @command{aclocal} searches for @file{.m4} files in the following
+directories, in this order:
+
+@table @code
+@item @var{acdir-APIVERSION}
+This is where the @file{.m4} macros distributed with Automake itself
+are stored. @var{APIVERSION} depends on the Automake release used;
+for example, for Automake 1.11.x, @var{APIVERSION} = @code{1.11}.
+
+@item @var{acdir}
+This directory is intended for third party @file{.m4} files, and is
+configured when @command{automake} itself is built. This is
+@file{@@datadir@@/aclocal/}, which typically
+expands to @file{$@{prefix@}/share/aclocal/}. To find the compiled-in
+value of @var{acdir}, use the @option{--print-ac-dir} option
+(@pxref{aclocal Options}).
+@end table
+
+As an example, suppose that @command{automake-1.11.2} was configured with
+@option{--prefix=@-/usr/local}. Then, the search path would be:
+
+@enumerate
+@item @file{/usr/local/share/aclocal-1.11.2/}
+@item @file{/usr/local/share/aclocal/}
+@end enumerate
+
+The paths for the @var{acdir} and @var{acdir-APIVERSION} directories can
+be changed respectively through aclocal options @option{--system-acdir}
+and @option{--automake-acdir} (@pxref{aclocal Options}). Note however
+that these options are only intended for use by the internal Automake
+test suite, or for debugging under highly unusual situations; they are
+not ordinarily needed by end-users.
+
+As explained in (@pxref{aclocal Options}), there are several options that
+can be used to change or extend this search path.
+
+@subsubheading Modifying the Macro Search Path: @samp{-I @var{dir}}
+
+Any extra directories specified using @option{-I} options
+(@pxref{aclocal Options}) are @emph{prepended} to this search list. Thus,
+@samp{aclocal -I /foo -I /bar} results in the following search path:
+
+@enumerate
+@item @file{/foo}
+@item @file{/bar}
+@item @var{acdir}-@var{APIVERSION}
+@item @var{acdir}
+@end enumerate
+
+@subsubheading Modifying the Macro Search Path: @file{dirlist}
+@cindex @file{dirlist}
+
+There is a third mechanism for customizing the search path. If a
+@file{dirlist} file exists in @var{acdir}, then that file is assumed to
+contain a list of directory patterns, one per line. @command{aclocal}
+expands these patterns to directory names, and adds them to the search
+list @emph{after} all other directories. @file{dirlist} entries may
+use shell wildcards such as @samp{*}, @samp{?}, or @code{[...]}.
+
+For example, suppose
+@file{@var{acdir}/dirlist} contains the following:
+
+@example
+/test1
+/test2
+/test3*
+@end example
+
+@noindent
+and that @command{aclocal} was called with the @samp{-I /foo -I /bar} options.
+Then, the search path would be
+
+@c @code looks better than @file here
+@enumerate
+@item @code{/foo}
+@item @code{/bar}
+@item @var{acdir}-@var{APIVERSION}
+@item @var{acdir}
+@item @code{/test1}
+@item @code{/test2}
+@end enumerate
+
+@noindent
+and all directories with path names starting with @code{/test3}.
+
+If the @option{--system-acdir=@var{dir}} option is used, then
+@command{aclocal} will search for the @file{dirlist} file in
+@var{dir}; but remember the warnings above against the use of
+@option{--system-acdir}.
+
+@file{dirlist} is useful in the following situation: suppose that
+@command{automake} version @code{1.11.2} is installed with
+@samp{--prefix=/usr} by the system vendor. Thus, the default search
+directories are
+
+@c @code looks better than @file here
+@enumerate
+@item @code{/usr/share/aclocal-1.11/}
+@item @code{/usr/share/aclocal/}
+@end enumerate
+
+However, suppose further that many packages have been manually
+installed on the system, with $prefix=/usr/local, as is typical. In
+that case, many of these ``extra'' @file{.m4} files are in
+@file{/usr/local/share/aclocal}. The only way to force
+@file{/usr/bin/aclocal} to find these ``extra'' @file{.m4} files is to
+always call @samp{aclocal -I /usr/local/share/aclocal}. This is
+inconvenient. With @file{dirlist}, one may create a file
+@file{/usr/share/aclocal/dirlist} containing only the single line
+
+@example
+/usr/local/share/aclocal
+@end example
+
+Now, the ``default'' search path on the affected system is
+
+@c @code looks better than @file here
+@enumerate
+@item @code{/usr/share/aclocal-1.11/}
+@item @code{/usr/share/aclocal/}
+@item @code{/usr/local/share/aclocal/}
+@end enumerate
+
+without the need for @option{-I} options; @option{-I} options can be reserved
+for project-specific needs (@file{my-source-dir/m4/}), rather than
+using it to work around local system-dependent tool installation
+directories.
+
+Similarly, @file{dirlist} can be handy if you have installed a local
+copy of Automake in your account and want @command{aclocal} to look for
+macros installed at other places on the system.
+
+@anchor{ACLOCAL_PATH}
+@subsubheading Modifying the Macro Search Path: @file{ACLOCAL_PATH}
+@cindex @env{ACLOCAL_PATH}
+
+The fourth and last mechanism to customize the macro search path is
+also the simplest. Any directory included in the colon-separated
+environment variable @env{ACLOCAL_PATH} is added to the search path
+@c Keep in sync with aclocal-path-precedence.sh
+and takes precedence over system directories (including those found via
+@file{dirlist}), with the exception of the versioned directory
+@var{acdir-APIVERSION} (@pxref{Macro Search Path}). However, directories
+passed via @option{-I} will take precedence over directories in
+@env{ACLOCAL_PATH}.
+
+@c Keep in sync with aclocal-path-installed.sh
+Also note that, if the @option{--install} option is used, any @file{.m4}
+file containing a required macro that is found in a directory listed in
+@env{ACLOCAL_PATH} will be installed locally.
+@c Keep in sync with aclocal-path-installed-serial.sh
+In this case, serial numbers in @file{.m4} are honoured too,
+@pxref{Serials}.
+
+Conversely to @file{dirlist}, @env{ACLOCAL_PATH} is useful if you are
+using a global copy of Automake and want @command{aclocal} to look for
+macros somewhere under your home directory.
+
+@subsubheading Planned future incompatibilities
+
+The order in which the directories in the macro search path are currently
+looked up is confusing and/or suboptimal in various aspects, and is
+probably going to be changed in the future Automake release. In
+particular, directories in @env{ACLOCAL_PATH} and @file{@var{acdir}}
+might end up taking precedence over @file{@var{acdir-APIVERSION}}, and
+directories in @file{@var{acdir}/dirlist} might end up taking precedence
+over @file{@var{acdir}}. @emph{This is a possible future incompatibility!}
+
+@node Extending aclocal
+@subsection Writing your own aclocal macros
+
+@cindex @command{aclocal}, extending
+@cindex Extending @command{aclocal}
+
+The @command{aclocal} program doesn't have any built-in knowledge of any
+macros, so it is easy to extend it with your own macros.
+
+This can be used by libraries that want to supply their own Autoconf
+macros for use by other programs. For instance, the @command{gettext}
+library supplies a macro @code{AM_GNU_GETTEXT} that should be used by
+any package using @command{gettext}. When the library is installed, it
+installs this macro so that @command{aclocal} will find it.
+
+A macro file's name should end in @file{.m4}. Such files should be
+installed in @file{$(datadir)/aclocal}. This is as simple as writing:
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+aclocaldir = $(datadir)/aclocal
+aclocal_DATA = mymacro.m4 myothermacro.m4
+@end example
+
+@noindent
+Please do use @file{$(datadir)/aclocal}, and not something based on
+the result of @samp{aclocal --print-ac-dir} (@pxref{Hard-Coded Install
+Paths}, for arguments). It might also be helpful to suggest to
+the user to add the @file{$(datadir)/aclocal} directory to his
+@env{ACLOCAL_PATH} variable (@pxref{ACLOCAL_PATH}) so that
+@command{aclocal} will find the @file{.m4} files installed by your
+package automatically.
+
+A file of macros should be a series of properly quoted
+@code{AC_DEFUN}'s (@pxref{Macro Definitions, , , autoconf, The
+Autoconf Manual}). The @command{aclocal} programs also understands
+@code{AC_REQUIRE} (@pxref{Prerequisite Macros, , , autoconf, The
+Autoconf Manual}), so it is safe to put each macro in a separate file.
+Each file should have no side effects but macro definitions.
+Especially, any call to @code{AC_PREREQ} should be done inside the
+defined macro, not at the beginning of the file.
+
+@cindex underquoted @code{AC_DEFUN}
+@acindex AC_DEFUN
+@acindex AC_PREREQ
+
+Starting with Automake 1.8, @command{aclocal} will warn about all
+underquoted calls to @code{AC_DEFUN}. We realize this will annoy a
+lot of people, because @command{aclocal} was not so strict in the past
+and many third party macros are underquoted; and we have to apologize
+for this temporary inconvenience. The reason we have to be stricter
+is that a future implementation of @command{aclocal} (@pxref{Future of
+aclocal}) will have to temporarily include all these third party
+@file{.m4} files, maybe several times, including even files that are
+not actually needed. Doing so should alleviate many problems of the
+current implementation, however it requires a stricter style from the
+macro authors. Hopefully it is easy to revise the existing macros.
+For instance,
+
+@example
+# bad style
+AC_PREREQ(2.68)
+AC_DEFUN(AX_FOOBAR,
+[AC_REQUIRE([AX_SOMETHING])dnl
+AX_FOO
+AX_BAR
+])
+@end example
+
+@noindent
+should be rewritten as
+
+@example
+AC_DEFUN([AX_FOOBAR],
+[AC_PREREQ([2.68])dnl
+AC_REQUIRE([AX_SOMETHING])dnl
+AX_FOO
+AX_BAR
+])
+@end example
+
+Wrapping the @code{AC_PREREQ} call inside the macro ensures that
+Autoconf 2.68 will not be required if @code{AX_FOOBAR} is not actually
+used. Most importantly, quoting the first argument of @code{AC_DEFUN}
+allows the macro to be redefined or included twice (otherwise this
+first argument would be expanded during the second definition). For
+consistency we like to quote even arguments such as @code{2.68} that
+do not require it.
+
+If you have been directed here by the @command{aclocal} diagnostic but
+are not the maintainer of the implicated macro, you will want to
+contact the maintainer of that macro. Please make sure you have the
+latest version of the macro and that the problem hasn't already been
+reported before doing so: people tend to work faster when they aren't
+flooded by mails.
+
+Another situation where @command{aclocal} is commonly used is to
+manage macros that are used locally by the package, @ref{Local
+Macros}.
+
+@node Local Macros
+@subsection Handling Local Macros
+
+Feature tests offered by Autoconf do not cover all needs. People
+often have to supplement existing tests with their own macros, or
+with third-party macros.
+
+There are two ways to organize custom macros in a package.
+
+The first possibility (the historical practice) is to list all your
+macros in @file{acinclude.m4}. This file will be included in
+@file{aclocal.m4} when you run @command{aclocal}, and its macro(s) will
+henceforth be visible to @command{autoconf}. However if it contains
+numerous macros, it will rapidly become difficult to maintain, and it
+will be almost impossible to share macros between packages.
+
+@vindex ACLOCAL_AMFLAGS
+The second possibility, which we do recommend, is to write each macro
+in its own file and gather all these files in a directory. This
+directory is usually called @file{m4/}. To build @file{aclocal.m4},
+one should therefore instruct @command{aclocal} to scan @file{m4/}.
+From the command line, this is done with @samp{aclocal -I m4}. The
+top-level @file{Makefile.am} should also be updated to define
+
+@example
+ACLOCAL_AMFLAGS = -I m4
+@end example
+
+@code{ACLOCAL_AMFLAGS} contains options to pass to @command{aclocal}
+when @file{aclocal.m4} is to be rebuilt by @command{make}. This line is
+also used by @command{autoreconf} (@pxref{autoreconf Invocation, ,
+Using @command{autoreconf} to Update @file{configure} Scripts,
+autoconf, The Autoconf Manual}) to run @command{aclocal} with suitable
+options, or by @command{autopoint} (@pxref{autopoint Invocation, ,
+Invoking the @command{autopoint} Program, gettext, GNU gettext tools})
+and @command{gettextize} (@pxref{gettextize Invocation, , Invoking the
+@command{gettextize} Program, gettext, GNU gettext tools}) to locate
+the place where Gettext's macros should be installed. So even if you
+do not really care about the rebuild rules, you should define
+@code{ACLOCAL_AMFLAGS}.
+
+When @samp{aclocal -I m4} is run, it will build an @file{aclocal.m4}
+that @code{m4_include}s any file from @file{m4/} that defines a
+required macro. Macros not found locally will still be searched in
+system-wide directories, as explained in @ref{Macro Search Path}.
+
+Custom macros should be distributed for the same reason that
+@file{configure.ac} is: so that other people have all the sources of
+your package if they want to work on it. Actually, this distribution
+happens automatically because all @code{m4_include}d files are
+distributed.
+
+However there is no consensus on the distribution of third-party
+macros that your package may use. Many libraries install their own
+macro in the system-wide @command{aclocal} directory (@pxref{Extending
+aclocal}). For instance, Guile ships with a file called
+@file{guile.m4} that contains the macro @code{GUILE_FLAGS} that can
+be used to define setup compiler and linker flags appropriate for
+using Guile. Using @code{GUILE_FLAGS} in @file{configure.ac} will
+cause @command{aclocal} to copy @file{guile.m4} into
+@file{aclocal.m4}, but as @file{guile.m4} is not part of the project,
+it will not be distributed. Technically, that means a user who
+needs to rebuild @file{aclocal.m4} will have to install Guile first.
+This is probably OK, if Guile already is a requirement to build the
+package. However, if Guile is only an optional feature, or if your
+package might run on architectures where Guile cannot be installed,
+this requirement will hinder development. An easy solution is to copy
+such third-party macros in your local @file{m4/} directory so they get
+distributed.
+
+Since Automake 1.10, @command{aclocal} offers an option to copy these
+system-wide third-party macros in your local macro directory, solving
+the above problem. Simply use:
+
+@example
+ACLOCAL_AMFLAGS = -I m4 --install
+@end example
+
+@noindent
+With this setup, system-wide macros will be copied to @file{m4/}
+the first time you run @command{autoreconf}. Then the locally
+installed macros will have precedence over the system-wide installed
+macros each time @command{aclocal} is run again.
+
+One reason why you should keep @option{--install} in the flags even
+after the first run is that when you later edit @file{configure.ac}
+and depend on a new macro, this macro will be installed in your
+@file{m4/} automatically. Another one is that serial numbers
+(@pxref{Serials}) can be used to update the macros in your source tree
+automatically when new system-wide versions are installed. A serial
+number should be a single line of the form
+
+@example
+#serial @var{nnn}
+@end example
+
+@noindent
+where @var{nnn} contains only digits and dots. It should appear in
+the M4 file before any macro definition. It is a good practice to
+maintain a serial number for each macro you distribute, even if you do
+not use the @option{--install} option of @command{aclocal}: this allows
+other people to use it.
+
+
+@node Serials
+@subsection Serial Numbers
+@cindex serial numbers in macros
+@cindex macro serial numbers
+@cindex @code{#serial} syntax
+@cindex @command{aclocal} and serial numbers
+
+Because third-party macros defined in @file{*.m4} files are naturally
+shared between multiple projects, some people like to version them.
+This makes it easier to tell which of two M4 files is newer. Since at
+least 1996, the tradition is to use a @samp{#serial} line for this.
+
+A serial number should be a single line of the form
+
+@example
+# serial @var{version}
+@end example
+
+@noindent
+where @var{version} is a version number containing only digits and
+dots. Usually people use a single integer, and they increment it each
+time they change the macro (hence the name of ``serial''). Such a
+line should appear in the M4 file before any macro definition.
+
+The @samp{#} must be the first character on the line,
+and it is OK to have extra words after the version, as in
+
+@example
+#serial @var{version} @var{garbage}
+@end example
+
+Normally these serial numbers are completely ignored by
+@command{aclocal} and @command{autoconf}, like any genuine comment.
+However when using @command{aclocal}'s @option{--install} feature, these
+serial numbers will modify the way @command{aclocal} selects the
+macros to install in the package: if two files with the same basename
+exist in your search path, and if at least one of them uses a
+@samp{#serial} line, @command{aclocal} will ignore the file that has
+the older @samp{#serial} line (or the file that has none).
+
+Note that a serial number applies to a whole M4 file, not to any macro
+it contains. A file can contains multiple macros, but only one
+serial.
+
+Here is a use case that illustrates the use of @option{--install} and
+its interaction with serial numbers. Let's assume we maintain a
+package called MyPackage, the @file{configure.ac} of which requires a
+third-party macro @code{AX_THIRD_PARTY} defined in
+@file{/usr/share/aclocal/thirdparty.m4} as follows:
+
+@example
+# serial 1
+AC_DEFUN([AX_THIRD_PARTY], [...])
+@end example
+
+MyPackage uses an @file{m4/} directory to store local macros as
+explained in @ref{Local Macros}, and has
+
+@example
+ACLOCAL_AMFLAGS = -I m4 --install
+@end example
+
+@noindent
+in its top-level @file{Makefile.am}.
+
+Initially the @file{m4/} directory is empty. The first time we run
+@command{autoreconf}, it will fetch the options to pass to
+@command{aclocal} in @file{Makefile.am}, and run @samp{aclocal -I m4
+--install}. @command{aclocal} will notice that
+
+@itemize @bullet
+@item
+@file{configure.ac} uses @code{AX_THIRD_PARTY}
+@item
+No local macros define @code{AX_THIRD_PARTY}
+@item
+@file{/usr/share/aclocal/thirdparty.m4} defines @code{AX_THIRD_PARTY}
+with serial 1.
+@end itemize
+
+@noindent
+Because @file{/usr/share/aclocal/thirdparty.m4} is a system-wide macro
+and @command{aclocal} was given the @option{--install} option, it will
+copy this file in @file{m4/thirdparty.m4}, and output an
+@file{aclocal.m4} that contains @samp{m4_include([m4/thirdparty.m4])}.
+
+The next time @samp{aclocal -I m4 --install} is run (either via
+@command{autoreconf}, by hand, or from the @file{Makefile} rebuild
+rules) something different happens. @command{aclocal} notices that
+
+@itemize @bullet
+@item
+@file{configure.ac} uses @code{AX_THIRD_PARTY}
+@item
+@file{m4/thirdparty.m4} defines @code{AX_THIRD_PARTY}
+with serial 1.
+@item
+@file{/usr/share/aclocal/thirdparty.m4} defines @code{AX_THIRD_PARTY}
+with serial 1.
+@end itemize
+
+@noindent
+Because both files have the same serial number, @command{aclocal} uses
+the first it found in its search path order (@pxref{Macro Search
+Path}). @command{aclocal} therefore ignores
+@file{/usr/share/aclocal/thirdparty.m4} and outputs an
+@file{aclocal.m4} that contains @samp{m4_include([m4/thirdparty.m4])}.
+
+Local directories specified with @option{-I} are always searched before
+system-wide directories, so a local file will always be preferred to
+the system-wide file in case of equal serial numbers.
+
+Now suppose the system-wide third-party macro is changed. This can
+happen if the package installing this macro is updated. Let's suppose
+the new macro has serial number 2. The next time @samp{aclocal -I m4
+--install} is run the situation is the following:
+
+@itemize @bullet
+@item
+@file{configure.ac} uses @code{AX_THIRD_PARTY}
+@item
+@file{m4/thirdparty.m4} defines @code{AX_THIRD_PARTY}
+with serial 1.
+@item
+@file{/usr/share/aclocal/thirdparty.m4} defines @code{AX_THIRD_PARTY}
+with serial 2.
+@end itemize
+
+@noindent
+When @command{aclocal} sees a greater serial number, it immediately
+forgets anything it knows from files that have the same basename and a
+smaller serial number. So after it has found
+@file{/usr/share/aclocal/thirdparty.m4} with serial 2,
+@command{aclocal} will proceed as if it had never seen
+@file{m4/thirdparty.m4}. This brings us back to a situation similar
+to that at the beginning of our example, where no local file defined
+the macro. @command{aclocal} will install the new version of the
+macro in @file{m4/thirdparty.m4}, in this case overriding the old
+version. MyPackage just had its macro updated as a side effect of
+running @command{aclocal}.
+
+If you are leery of letting @command{aclocal} update your local macro,
+you can run @samp{aclocal -I m4 --diff} to review the changes
+@samp{aclocal -I m4 --install} would perform on these macros.
+
+Finally, note that the @option{--force} option of @command{aclocal} has
+absolutely no effect on the files installed by @option{--install}. For
+instance, if you have modified your local macros, do not expect
+@option{--install --force} to replace the local macros by their
+system-wide versions. If you want to do so, simply erase the local
+macros you want to revert, and run @samp{aclocal -I m4 --install}.
+
+
+@node Future of aclocal
+@subsection The Future of @command{aclocal}
+@cindex @command{aclocal}'s scheduled death
+
+@command{aclocal} is expected to disappear. This feature really
+should not be offered by Automake. Automake should focus on
+generating @file{Makefile}s; dealing with M4 macros really is
+Autoconf's job. The fact that some people install Automake just to use
+@command{aclocal}, but do not use @command{automake} otherwise is an
+indication of how that feature is misplaced.
+
+The new implementation will probably be done slightly differently.
+For instance, it could enforce the @file{m4/}-style layout discussed in
+@ref{Local Macros}.
+
+We have no idea when and how this will happen. This has been
+discussed several times in the past, but someone still has to commit
+to that non-trivial task.
+
+From the user point of view, @command{aclocal}'s removal might turn
+out to be painful. There is a simple precaution that you may take to
+make that switch more seamless: never call @command{aclocal} yourself.
+Keep this guy under the exclusive control of @command{autoreconf} and
+Automake's rebuild rules. Hopefully you won't need to worry about
+things breaking, when @command{aclocal} disappears, because everything
+will have been taken care of. If otherwise you used to call
+@command{aclocal} directly yourself or from some script, you will
+quickly notice the change.
+
+Many packages come with a script called @file{bootstrap.sh} or
+@file{autogen.sh}, that will just call @command{aclocal},
+@command{libtoolize}, @command{gettextize} or @command{autopoint},
+@command{autoconf}, @command{autoheader}, and @command{automake} in
+the right order. Actually this is precisely what @command{autoreconf}
+can do for you. If your package has such a @file{bootstrap.sh} or
+@file{autogen.sh} script, consider using @command{autoreconf}. That
+should simplify its logic a lot (less things to maintain, yum!), it's
+even likely you will not need the script anymore, and more to the point
+you will not call @command{aclocal} directly anymore.
+
+For the time being, third-party packages should continue to install
+public macros into @file{/usr/share/aclocal/}. If @command{aclocal}
+is replaced by another tool it might make sense to rename the
+directory, but supporting @file{/usr/share/aclocal/} for backward
+compatibility should be really easy provided all macros are properly
+written (@pxref{Extending aclocal}).
+
+
+
+@node Macros
+@section Autoconf macros supplied with Automake

+@item AM_INIT_AUTOMAKE([OPTIONS])
+@acindex AM_INIT_AUTOMAKE
+Runs many macros required for proper operation of the generated Makefiles.
+
+@vindex AUTOMAKE_OPTIONS
+Today, @code{AM_INIT_AUTOMAKE} is called with a single argument: a
+space-separated list of Automake options that should
+be applied to every @file{Makefile.am} in the tree. The effect is as if
+each option were listed in @code{AUTOMAKE_OPTIONS} (@pxref{Options}).
+
+@acindex AC_INIT
+This macro can also be called in @emph{another, deprecated form} (support
+for which will be @emph{removed in the next major Automake release (1.13)}):
+@code{AM_INIT_AUTOMAKE(PACKAGE, VERSION, [NO-DEFINE])}. In this form,
+there are two required arguments: the package and the version number.
+This form is obsolete because the @var{package} and @var{version} can
+be obtained from Autoconf's @code{AC_INIT} macro (which itself has an
+old and a new form).
+
+@anchor{Modernize AM_INIT_AUTOMAKE invocation}
+If your @file{configure.ac} has:
+
+@example
+AC_INIT([src/foo.c])
+AM_INIT_AUTOMAKE([mumble], [1.5])
+@end example
+
+@noindent
+you should modernize it as follows:
+
+@example
+AC_INIT([mumble], [1.5])
+AC_CONFIG_SRCDIR([src/foo.c])
+AM_INIT_AUTOMAKE
+@end example
+
+Note that if you're upgrading your @file{configure.ac} from an earlier
+version of Automake, it is not always correct to simply move the
+package and version arguments from @code{AM_INIT_AUTOMAKE} directly to
+@code{AC_INIT}, as in the example above. The first argument to
+@code{AC_INIT} should be the name of your package (e.g., @samp{GNU
+Automake}), not the tarball name (e.g., @samp{automake}) that you used
+to pass to @code{AM_INIT_AUTOMAKE}. Autoconf tries to derive a
+tarball name from the package name, which should work for most but not
+all package names. (If it doesn't work for yours, you can use the
+four-argument form of @code{AC_INIT} to provide the tarball name
+explicitly).
+
+@cindex @code{PACKAGE}, prevent definition
+@cindex @code{VERSION}, prevent definition
+@opindex no-define
+By default this macro @code{AC_DEFINE}'s @code{PACKAGE} and

+
+@item AM_PATH_LISPDIR

+@vindex EMACS
+@vindex lispdir
+Searches for the program @command{emacs}, and, if found, sets the
+output variable @code{lispdir} to the full path to Emacs' site-lisp
+directory.
+
+Note that this test assumes the @command{emacs} found to be a version
+that supports Emacs Lisp (such as GNU Emacs or XEmacs). Other
+emacsen can cause this test to hang (some, like old versions of
+MicroEmacs, start up in interactive mode, requiring @kbd{C-x C-c} to
+exit, which is hardly obvious for a non-emacs user). In most cases,
+however, you should be able to use @kbd{C-c} to kill the test. In
+order to avoid problems, you can set @env{EMACS} to ``no'' in the
+environment, or use the @option{--with-lispdir} option to
+@command{configure} to explicitly set the correct path (if you're sure
+you have an @command{emacs} that supports Emacs Lisp).
+
+@item AM_PROG_AR(@ovar{act-if-fail})
+@acindex AM_PROG_AR
+@vindex AR
+You must use this macro when you use the archiver in your project, if
+you want support for unusual archivers such as Microsoft @command{lib}.

+
+Nowadays Autoconf provides a similar functionality with

+@node Directories
+@chapter Directories
+
+For simple projects that distribute all files in the same directory
+it is enough to have a single @file{Makefile.am} that builds
+everything in place.
+
+In larger projects it is common to organize files in different
+directories, in a tree. For instance one directory per program, per
+library or per module. The traditional approach is to build these
+subdirectories recursively: each directory contains its @file{Makefile}
+(generated from @file{Makefile.am}), and when @command{make} is run
+from the top level directory it enters each subdirectory in turn to
+build its contents.

+@end menu
+
+@node Subdirectories
+@section Recursing subdirectories
+
+@cindex @code{SUBDIRS}, explained
+
+In packages with subdirectories, the top level @file{Makefile.am} must
+tell Automake which subdirectories are to be built. This is done via
+the @code{SUBDIRS} variable.
+@vindex SUBDIRS
+
+The @code{SUBDIRS} variable holds a list of subdirectories in which
+building of various sorts can occur. The rules for many targets
+(e.g., @code{all}) in the generated @file{Makefile} will run commands
+both locally and in all specified subdirectories. Note that the
+directories listed in @code{SUBDIRS} are not required to contain
+@file{Makefile.am}s; only @file{Makefile}s (after configuration).
+This allows inclusion of libraries from packages that do not use
+Automake (such as @code{gettext}; see also @ref{Third-Party
+Makefiles}).
+
+In packages that use subdirectories, the top-level @file{Makefile.am} is
+often very short. For instance, here is the @file{Makefile.am} from the
+GNU Hello distribution:
+
+@example
+EXTRA_DIST = BUGS ChangeLog.O README-alpha
+SUBDIRS = doc intl po src tests
+@end example
+
+When Automake invokes @command{make} in a subdirectory, it uses the value
+of the @code{MAKE} variable. It passes the value of the variable
+@code{AM_MAKEFLAGS} to the @command{make} invocation; this can be set in
+@file{Makefile.am} if there are flags you must always pass to
+@command{make}.
+@vindex MAKE
+@vindex AM_MAKEFLAGS
+
+The directories mentioned in @code{SUBDIRS} are usually direct
+children of the current directory, each subdirectory containing its
+own @file{Makefile.am} with a @code{SUBDIRS} pointing to deeper
+subdirectories. Automake can be used to construct packages of
+arbitrary depth this way.
+
+By default, Automake generates @file{Makefiles} that work depth-first
+in postfix order: the subdirectories are built before the current
+directory. However, it is possible to change this ordering. You can
+do this by putting @samp{.} into @code{SUBDIRS}. For instance,
+putting @samp{.} first will cause a prefix ordering of
+directories.
+
+Using
+
+@example
+SUBDIRS = lib src . test
+@end example
+
+@noindent
+will cause @file{lib/} to be built before @file{src/}, then the
+current directory will be built, finally the @file{test/} directory
+will be built. It is customary to arrange test directories to be
+built after everything else since they are meant to test what has
+been constructed.
+
+All @code{clean} rules are run in reverse order of build rules.
+
+@node Conditional Subdirectories
+@section Conditional Subdirectories
+@cindex Subdirectories, building conditionally
+@cindex Conditional subdirectories
+@cindex @code{SUBDIRS}, conditional
+@cindex Conditional @code{SUBDIRS}
+
+It is possible to define the @code{SUBDIRS} variable conditionally if,
+like in the case of GNU Inetutils, you want to only build a subset of
+the entire package.
+
+To illustrate how this works, let's assume we have two directories
+@file{src/} and @file{opt/}. @file{src/} should always be built, but we
+want to decide in @command{configure} whether @file{opt/} will be built
+or not. (For this example we will assume that @file{opt/} should be
+built when the variable @samp{$want_opt} was set to @samp{yes}.)
+
+Running @command{make} should thus recurse into @file{src/} always, and
+then maybe in @file{opt/}.
+
+However @samp{make dist} should always recurse into both @file{src/}
+and @file{opt/}. Because @file{opt/} should be distributed even if it
+is not needed in the current configuration. This means
+@file{opt/Makefile} should be created @emph{unconditionally}.
+
+There are two ways to setup a project like this. You can use Automake
+conditionals (@pxref{Conditionals}) or use Autoconf @code{AC_SUBST}
+variables (@pxref{Setting Output Variables, , Setting Output
+Variables, autoconf, The Autoconf Manual}). Using Automake
+conditionals is the preferred solution. Before we illustrate these
+two possibilities, let's introduce @code{DIST_SUBDIRS}.
+

+
+@node SUBDIRS vs DIST_SUBDIRS
+@subsection @code{SUBDIRS} vs.@: @code{DIST_SUBDIRS}
+@cindex @code{DIST_SUBDIRS}, explained
+
+Automake considers two sets of directories, defined by the variables
+@code{SUBDIRS} and @code{DIST_SUBDIRS}.
+
+@code{SUBDIRS} contains the subdirectories of the current directory
+that must be built (@pxref{Subdirectories}). It must be defined
+manually; Automake will never guess a directory is to be built. As we
+will see in the next two sections, it is possible to define it
+conditionally so that some directory will be omitted from the build.
+
+@code{DIST_SUBDIRS} is used in rules that need to recurse in all
+directories, even those that have been conditionally left out of the
+build. Recall our example where we may not want to build subdirectory
+@file{opt/}, but yet we want to distribute it? This is where
+@code{DIST_SUBDIRS} comes into play: @samp{opt} may not appear in
+@code{SUBDIRS}, but it must appear in @code{DIST_SUBDIRS}.
+
+Precisely, @code{DIST_SUBDIRS} is used by @samp{make
+maintainer-clean}, @samp{make distclean} and @samp{make dist}. All
+other recursive rules use @code{SUBDIRS}.
+
+If @code{SUBDIRS} is defined conditionally using Automake
+conditionals, Automake will define @code{DIST_SUBDIRS} automatically
+from the possible values of @code{SUBDIRS} in all conditions.
+
+If @code{SUBDIRS} contains @code{AC_SUBST} variables,
+@code{DIST_SUBDIRS} will not be defined correctly because Automake
+does not know the possible values of these variables. In this case
+@code{DIST_SUBDIRS} needs to be defined manually.
+
+@node Subdirectories with AM_CONDITIONAL
+@subsection Subdirectories with @code{AM_CONDITIONAL}
+@cindex @code{SUBDIRS} and @code{AM_CONDITIONAL}
+@cindex @code{AM_CONDITIONAL} and @code{SUBDIRS}
+
+@c Keep in sync with subcond2.sh
+
+@file{configure} should output the @file{Makefile} for each directory
+and define a condition into which @file{opt/} should be built.
+
+@example
+@dots{}
+AM_CONDITIONAL([COND_OPT], [test "$want_opt" = yes])
+AC_CONFIG_FILES([Makefile src/Makefile opt/Makefile])
+@dots{}
+@end example
+
+Then @code{SUBDIRS} can be defined in the top-level @file{Makefile.am}
+as follows.
+
+@example
+if COND_OPT
+ MAYBE_OPT = opt
+endif
+SUBDIRS = src $(MAYBE_OPT)
+@end example
+
+As you can see, running @command{make} will rightly recurse into
+@file{src/} and maybe @file{opt/}.
+
+@vindex DIST_SUBDIRS
+As you can't see, running @samp{make dist} will recurse into both
+@file{src/} and @file{opt/} directories because @samp{make dist}, unlike
+@samp{make all}, doesn't use the @code{SUBDIRS} variable. It uses the
+@code{DIST_SUBDIRS} variable.
+
+In this case Automake will define @samp{DIST_SUBDIRS = src opt}
+automatically because it knows that @code{MAYBE_OPT} can contain
+@samp{opt} in some condition.
+
+@node Subdirectories with AC_SUBST
+@subsection Subdirectories with @code{AC_SUBST}
+@cindex @code{SUBDIRS} and @code{AC_SUBST}
+@cindex @code{AC_SUBST} and @code{SUBDIRS}
+
+@c Keep in sync with subcond3.sh
+
+Another possibility is to define @code{MAYBE_OPT} from
+@file{./configure} using @code{AC_SUBST}:
+
+@example
+@dots{}
+if test "$want_opt" = yes; then
+ MAYBE_OPT=opt
+else
+ MAYBE_OPT=
+fi
+AC_SUBST([MAYBE_OPT])
+AC_CONFIG_FILES([Makefile src/Makefile opt/Makefile])
+@dots{}
+@end example
+
+In this case the top-level @file{Makefile.am} should look as follows.
+
+@example
+SUBDIRS = src $(MAYBE_OPT)
+DIST_SUBDIRS = src opt
+@end example
+
+The drawback is that since Automake cannot guess what the possible
+values of @code{MAYBE_OPT} are, it is necessary to define
+@code{DIST_SUBDIRS}.
+
+@node Unconfigured Subdirectories
+@subsection Unconfigured Subdirectories
+@cindex Subdirectories, configured conditionally
+
+The semantics of @code{DIST_SUBDIRS} are often misunderstood by some
+users that try to @emph{configure and build} subdirectories
+conditionally. Here by configuring we mean creating the
+@file{Makefile} (it might also involve running a nested
+@command{configure} script: this is a costly operation that explains
+why people want to do it conditionally, but only the @file{Makefile}
+is relevant to the discussion).
+
+The above examples all assume that every @file{Makefile} is created,
+even in directories that are not going to be built. The simple reason
+is that we want @samp{make dist} to distribute even the directories
+that are not being built (e.g., platform-dependent code), hence
+@file{make dist} must recurse into the subdirectory, hence this
+directory must be configured and appear in @code{DIST_SUBDIRS}.
+
+Building packages that do not configure every subdirectory is a tricky
+business, and we do not recommend it to the novice as it is easy to
+produce an incomplete tarball by mistake. We will not discuss this
+topic in depth here, yet for the adventurous here are a few rules to
+remember.
+
+@cartouche
+@itemize
+@item @code{SUBDIRS} should always be a subset of @code{DIST_SUBDIRS}.
+
+It makes little sense to have a directory in @code{SUBDIRS} that
+is not in @code{DIST_SUBDIRS}. Think of the former as a way to tell
+which directories listed in the latter should be built.
+@item Any directory listed in @code{DIST_SUBDIRS} and @code{SUBDIRS}
+must be configured.
+
+I.e., the @file{Makefile} must exists or the recursive @command{make}
+rules will not be able to process the directory.
+@item Any configured directory must be listed in @code{DIST_SUBDIRS}.
+
+So that the cleaning rules remove the generated @file{Makefile}s.
+It would be correct to see @code{DIST_SUBDIRS} as a variable that
+lists all the directories that have been configured.
+@end itemize
+@end cartouche
+
+In order to prevent recursion in some unconfigured directory you
+must therefore ensure that this directory does not appear in
+@code{DIST_SUBDIRS} (and @code{SUBDIRS}). For instance, if you define
+@code{SUBDIRS} conditionally using @code{AC_SUBST} and do not define
+@code{DIST_SUBDIRS} explicitly, it will be default to
+@samp{$(SUBDIRS)}; another possibility is to force @code{DIST_SUBDIRS
+= $(SUBDIRS)}.
+
+Of course, directories that are omitted from @code{DIST_SUBDIRS} will
+not be distributed unless you make other arrangements for this to
+happen (for instance, always running @samp{make dist} in a
+configuration where all directories are known to appear in
+@code{DIST_SUBDIRS}; or writing a @code{dist-hook} target to
+distribute these directories).
+
+@cindex Subdirectories, not distributed
+In few packages, unconfigured directories are not even expected to
+be distributed. Although these packages do not require the
+aforementioned extra arrangements, there is another pitfall. If the
+name of a directory appears in @code{SUBDIRS} or @code{DIST_SUBDIRS},
+@command{automake} will make sure the directory exists. Consequently
+@command{automake} cannot be run on such a distribution when one
+directory has been omitted. One way to avoid this check is to use the
+@code{AC_SUBST} method to declare conditional directories; since
+@command{automake} does not know the values of @code{AC_SUBST}
+variables it cannot ensure the corresponding directory exists.
+
+@node Alternative
+@section An Alternative Approach to Subdirectories
+
+If you've ever read Peter Miller's excellent paper,
+@uref{http://miller.emu.id.au/pmiller/books/rmch/,
+Recursive Make Considered Harmful}, the preceding sections on the use of
+subdirectories will probably come as unwelcome advice. For those who
+haven't read the paper, Miller's main thesis is that recursive
+@command{make} invocations are both slow and error-prone.
+
+Automake provides sufficient cross-directory support @footnote{We
+believe. This work is new and there are probably warts.
+@xref{Introduction}, for information on reporting bugs.} to enable you
+to write a single @file{Makefile.am} for a complex multi-directory
+package.
+
+
+By default an installable file specified in a subdirectory will have its
+directory name stripped before installation. For instance, in this
+example, the header file will be installed as
+@file{$(includedir)/stdio.h}:
+
+@example
+include_HEADERS = inc/stdio.h
+@end example
+
+@vindex nobase_
+@cindex @code{nobase_} prefix
+@cindex Path stripping, avoiding
+@cindex Avoiding path stripping
+
+However, the @samp{nobase_} prefix can be used to circumvent this path
+stripping. In this example, the header file will be installed as
+@file{$(includedir)/sys/types.h}:
+
+@example
+nobase_include_HEADERS = sys/types.h
+@end example
+
+@cindex @code{nobase_} and @code{dist_} or @code{nodist_}
+@cindex @code{dist_} and @code{nobase_}
+@cindex @code{nodist_} and @code{nobase_}
+@vindex dist_
+@vindex nodist_
+
+@samp{nobase_} should be specified first when used in conjunction with
+either @samp{dist_} or @samp{nodist_} (@pxref{Fine-grained Distribution
+Control}). For instance:
+
+@example
+nobase_dist_pkgdata_DATA = images/vortex.pgm sounds/whirl.ogg
+@end example
+
+Finally, note that a variable using the @samp{nobase_} prefix can
+often be replaced by several variables, one for each destination
+directory (@pxref{Uniform}). For instance, the last example could be
+rewritten as follows:
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+imagesdir = $(pkgdatadir)/images
+soundsdir = $(pkgdatadir)/sounds
+dist_images_DATA = images/vortex.pgm
+dist_sounds_DATA = sounds/whirl.ogg
+@end example
+
+@noindent
+This latter syntax makes it possible to change one destination
+directory without changing the layout of the source tree.
+
+Currently, @samp{nobase_*_LTLIBRARIES} are the only exception to this
+rule, in that there is no particular installation order guarantee for
+an otherwise equivalent set of variables without @samp{nobase_} prefix.
+
+@node Subpackages
+@section Nesting Packages
+@cindex Nesting packages
+@cindex Subpackages
+@acindex AC_CONFIG_SUBDIRS
+@acindex AC_CONFIG_AUX_DIR
+
+
+In the GNU Build System, packages can be nested to arbitrary depth.
+This means that a package can embed other packages with their own
+@file{configure}, @file{Makefile}s, etc.
+
+These other packages should just appear as subdirectories of their
+parent package. They must be listed in @code{SUBDIRS} like other
+ordinary directories. However the subpackage's @file{Makefile}s
+should be output by its own @file{configure} script, not by the
+parent's @file{configure}. This is achieved using the
+@code{AC_CONFIG_SUBDIRS} Autoconf macro (@pxref{Subdirectories,
+AC_CONFIG_SUBDIRS, Configuring Other Packages in Subdirectories,
+autoconf, The Autoconf Manual}).
+
+Here is an example package for an @code{arm} program that links with
+a @code{hand} library that is a nested package in subdirectory
+@file{hand/}.
+
+@code{arm}'s @file{configure.ac}:
+
+@example
+AC_INIT([arm], [1.0])
+AC_CONFIG_AUX_DIR([.])
+AM_INIT_AUTOMAKE
+AC_PROG_CC
+AC_CONFIG_FILES([Makefile])
+# Call hand's ./configure script recursively.
+AC_CONFIG_SUBDIRS([hand])
+AC_OUTPUT
+@end example
+
+@code{arm}'s @file{Makefile.am}:
+
+@example
+# Build the library in the hand subdirectory first.
+SUBDIRS = hand
+
+# Include hand's header when compiling this directory.
+AM_CPPFLAGS = -I$(srcdir)/hand
+
+bin_PROGRAMS = arm
+arm_SOURCES = arm.c
+# link with the hand library.
+arm_LDADD = hand/libhand.a
+@end example
+
+Now here is @code{hand}'s @file{hand/configure.ac}:
+
+@example
+AC_INIT([hand], [1.2])
+AC_CONFIG_AUX_DIR([.])
+AM_INIT_AUTOMAKE
+AC_PROG_CC
+AM_PROG_AR
+AC_PROG_RANLIB
+AC_CONFIG_FILES([Makefile])
+AC_OUTPUT
+@end example
+
+@noindent
+and its @file{hand/Makefile.am}:
+
+@example
+lib_LIBRARIES = libhand.a
+libhand_a_SOURCES = hand.c
+@end example
+
+When @samp{make dist} is run from the top-level directory it will
+create an archive @file{arm-1.0.tar.gz} that contains the @code{arm}
+code as well as the @file{hand} subdirectory. This package can be
+built and installed like any ordinary package, with the usual
+@samp{./configure && make && make install} sequence (the @code{hand}
+subpackage will be built and installed by the process).
+
+When @samp{make dist} is run from the hand directory, it will create a
+self-contained @file{hand-1.2.tar.gz} archive. So although it appears
+to be embedded in another package, it can still be used separately.
+
+The purpose of the @samp{AC_CONFIG_AUX_DIR([.])} instruction is to
+force Automake and Autoconf to search for auxiliary scripts in the
+current directory. For instance, this means that there will be two
+copies of @file{install-sh}: one in the top-level of the @code{arm}
+package, and another one in the @file{hand/} subdirectory for the
+@code{hand} package.
+
+The historical default is to search for these auxiliary scripts in
+the parent directory and the grandparent directory. So if the
+@samp{AC_CONFIG_AUX_DIR([.])} line was removed from
+@file{hand/configure.ac}, that subpackage would share the auxiliary
+script of the @code{arm} package. This may looks like a gain in size
+(a few kilobytes), but it is actually a loss of modularity as the
+@code{hand} subpackage is no longer self-contained (@samp{make dist}
+in the subdirectory will not work anymore).
+
+Packages that do not use Automake need more work to be integrated this
+way. @xref{Third-Party Makefiles}.

+@node A Program
+@section Building a program
+
+In order to build a program, you need to tell Automake which sources
+are part of it, and which libraries it should be linked with.
+
+This section also covers conditional compilation of sources or
+programs. Most of the comments about these also apply to libraries
+(@pxref{A Library}) and libtool libraries (@pxref{A Shared Library}).

+@subsection Defining program sources
+
+@cindex @code{PROGRAMS}, @code{bindir}
+@vindex _PROGRAMS
+@vindex bin_PROGRAMS
+@vindex sbin_PROGRAMS
+@vindex libexec_PROGRAMS
+@vindex pkglibexec_PROGRAMS
+@vindex noinst_PROGRAMS
+@vindex check_PROGRAMS
+
+In a directory containing source that gets built into a program (as
+opposed to a library or a script), the @code{PROGRAMS} primary is used.
+Programs can be installed in @code{bindir}, @code{sbindir},
+@code{libexecdir}, @code{pkglibexecdir}, or not at all
+(@code{noinst_}). They can also be built only for @samp{make check}, in
+which case the prefix is @samp{check_}.
+
+For instance:
+
+@example
+bin_PROGRAMS = hello
+@end example
+
+In this simple case, the resulting @file{Makefile.in} will contain code
+to generate a program named @code{hello}.
+
+Associated with each program are several assisting variables that are
+named after the program. These variables are all optional, and have
+reasonable defaults. Each variable, its use, and default is spelled out
+below; we use the ``hello'' example throughout.
+
+The variable @code{hello_SOURCES} is used to specify which source files
+get built into an executable:
+
+@example
+hello_SOURCES = hello.c version.c getopt.c getopt1.c getopt.h system.h
+@end example
+
+This causes each mentioned @file{.c} file to be compiled into the
+corresponding @file{.o}. Then all are linked to produce @file{hello}.
+
+@cindex @code{_SOURCES} primary, defined
+@cindex @code{SOURCES} primary, defined
+@cindex Primary variable, @code{SOURCES}
+@vindex _SOURCES
+
+If @code{hello_SOURCES} is not specified, then it defaults to the single
+file @file{hello.c} (@pxref{Default _SOURCES}).
+@vindex _SOURCES
+@vindex SOURCES
+
+Multiple programs can be built in a single directory. Multiple programs
+can share a single source file, which must be listed in each
+@code{_SOURCES} definition.
+
+@cindex Header files in @code{_SOURCES}
+@cindex @code{_SOURCES} and header files
+
+Header files listed in a @code{_SOURCES} definition will be included in
+the distribution but otherwise ignored. In case it isn't obvious, you
+should not include the header file generated by @file{configure} in a
+@code{_SOURCES} variable; this file should not be distributed. Lex
+(@file{.l}) and Yacc (@file{.y}) files can also be listed; see @ref{Yacc
+and Lex}.
+
+
+@node Linking
+@subsection Linking the program
+
+If you need to link against libraries that are not found by
+@command{configure}, you can use @code{LDADD} to do so. This variable is
+used to specify additional objects or libraries to link with; it is
+inappropriate for specifying specific linker flags, you should use
+@code{AM_LDFLAGS} for this purpose.
+@vindex LDADD
+@vindex AM_LDFLAGS
+
+@cindex @code{prog_LDADD}, defined
+
+Sometimes, multiple programs are built in one directory but do not share
+the same link-time requirements. In this case, you can use the
+@code{@var{prog}_LDADD} variable (where @var{prog} is the name of the
+program as it appears in some @code{_PROGRAMS} variable, and usually
+written in lowercase) to override @code{LDADD}. If this variable exists
+for a given program, then that program is not linked using @code{LDADD}.
+@vindex maude_LDADD
+
+For instance, in GNU cpio, @code{pax}, @code{cpio} and @code{mt} are
+linked against the library @file{libcpio.a}. However, @code{rmt} is
+built in the same directory, and has no such link requirement. Also,
+@code{mt} and @code{rmt} are only built on certain architectures. Here
+is what cpio's @file{src/Makefile.am} looks like (abridged):
+
+@example
+bin_PROGRAMS = cpio pax $(MT)
+libexec_PROGRAMS = $(RMT)
+EXTRA_PROGRAMS = mt rmt
+
+LDADD = ../lib/libcpio.a $(INTLLIBS)
+rmt_LDADD =
+
+cpio_SOURCES = @dots{}
+pax_SOURCES = @dots{}
+mt_SOURCES = @dots{}
+rmt_SOURCES = @dots{}
+@end example
+
+@cindex @code{_LDFLAGS}, defined
+@vindex maude_LDFLAGS
+@code{@var{prog}_LDADD} is inappropriate for passing program-specific
+linker flags (except for @option{-l}, @option{-L}, @option{-dlopen} and
+@option{-dlpreopen}). So, use the @code{@var{prog}_LDFLAGS} variable for
+this purpose.
+
+@cindex @code{_DEPENDENCIES}, defined
+@vindex maude_DEPENDENCIES
+@vindex EXTRA_maude_DEPENDENCIES
+It is also occasionally useful to have a program depend on some other
+target that is not actually part of that program. This can be done
+using either the @code{@var{prog}_DEPENDENCIES} or the
+@code{EXTRA_@var{prog}_DEPENDENCIES} variable. Each program depends on
+the contents both variables, but no further interpretation is done.
+
+Since these dependencies are associated to the link rule used to
+create the programs they should normally list files used by the link
+command. That is @file{*.$(OBJEXT)}, @file{*.a}, or @file{*.la}
+files. In rare cases you may need to add other kinds of files such as
+linker scripts, but @emph{listing a source file in
+@code{_DEPENDENCIES} is wrong}. If some source file needs to be built
+before all the components of a program are built, consider using the
+@code{BUILT_SOURCES} variable instead (@pxref{Sources}).
+
+If @code{@var{prog}_DEPENDENCIES} is not supplied, it is computed by
+Automake. The automatically-assigned value is the contents of
+@code{@var{prog}_LDADD}, with most configure substitutions, @option{-l},
+@option{-L}, @option{-dlopen} and @option{-dlpreopen} options removed. The
+configure substitutions that are left in are only @samp{$(LIBOBJS)} and
+@samp{$(ALLOCA)}; these are left because it is known that they will not
+cause an invalid value for @code{@var{prog}_DEPENDENCIES} to be
+generated.
+
+@ref{Conditional Sources} shows a situation where @code{_DEPENDENCIES}
+may be used.
+
+The @code{EXTRA_@var{prog}_DEPENDENCIES} may be useful for cases where
+you merely want to augment the @command{automake}-generated
+@code{@var{prog}_DEPENDENCIES} rather than replacing it.
+
+@cindex @code{LDADD} and @option{-l}
+@cindex @option{-l} and @code{LDADD}
+We recommend that you avoid using @option{-l} options in @code{LDADD}
+or @code{@var{prog}_LDADD} when referring to libraries built by your
+package. Instead, write the file name of the library explicitly as in
+the above @code{cpio} example. Use @option{-l} only to list
+third-party libraries. If you follow this rule, the default value of
+@code{@var{prog}_DEPENDENCIES} will list all your local libraries and
+omit the other ones.
+
+
+@node Conditional Sources
+@subsection Conditional compilation of sources
+
+You can't put a configure substitution (e.g., @samp{@@FOO@@} or
+@samp{$(FOO)} where @code{FOO} is defined via @code{AC_SUBST}) into a
+@code{_SOURCES} variable. The reason for this is a bit hard to
+explain, but suffice to say that it simply won't work. Automake will
+give an error if you try to do this.
+
+Fortunately there are two other ways to achieve the same result. One is
+to use configure substitutions in @code{_LDADD} variables, the other is
+to use an Automake conditional.
+
+@subsubheading Conditional Compilation using @code{_LDADD} Substitutions
+
+@cindex @code{EXTRA_prog_SOURCES}, defined
+
+Automake must know all the source files that could possibly go into a
+program, even if not all the files are built in every circumstance. Any
+files that are only conditionally built should be listed in the
+appropriate @code{EXTRA_} variable. For instance, if
+@file{hello-linux.c} or @file{hello-generic.c} were conditionally included
+in @code{hello}, the @file{Makefile.am} would contain:
+
+@example
+bin_PROGRAMS = hello
+hello_SOURCES = hello-common.c
+EXTRA_hello_SOURCES = hello-linux.c hello-generic.c
+hello_LDADD = $(HELLO_SYSTEM)
+hello_DEPENDENCIES = $(HELLO_SYSTEM)
+@end example
+
+@noindent
+You can then setup the @samp{$(HELLO_SYSTEM)} substitution from
+@file{configure.ac}:
+
+@example
+@dots{}
+case $host in
+ *linux*) HELLO_SYSTEM='hello-linux.$(OBJEXT)' ;;
+ *) HELLO_SYSTEM='hello-generic.$(OBJEXT)' ;;
+esac
+AC_SUBST([HELLO_SYSTEM])
+@dots{}
+@end example
+
+In this case, the variable @code{HELLO_SYSTEM} should be replaced by
+either @file{hello-linux.o} or @file{hello-generic.o}, and added to
+both @code{hello_DEPENDENCIES} and @code{hello_LDADD} in order to be
+built and linked in.
+
+@subsubheading Conditional Compilation using Automake Conditionals
+
+An often simpler way to compile source files conditionally is to use
+Automake conditionals. For instance, you could use this
+@file{Makefile.am} construct to build the same @file{hello} example:
+
+@example
+bin_PROGRAMS = hello
+if LINUX
+hello_SOURCES = hello-linux.c hello-common.c
+else
+hello_SOURCES = hello-generic.c hello-common.c
+endif
+@end example
+
+In this case, @file{configure.ac} should setup the @code{LINUX}
+conditional using @code{AM_CONDITIONAL} (@pxref{Conditionals}).
+
+When using conditionals like this you don't need to use the
+@code{EXTRA_} variable, because Automake will examine the contents of
+each variable to construct the complete list of source files.
+
+If your program uses a lot of files, you will probably prefer a
+conditional @samp{+=}.
+
+@example
+bin_PROGRAMS = hello
+hello_SOURCES = hello-common.c
+if LINUX
+hello_SOURCES += hello-linux.c
+else
+hello_SOURCES += hello-generic.c
+endif
+@end example
+
+@node Conditional Programs
+@subsection Conditional compilation of programs
+@cindex Conditional programs
+@cindex Programs, conditional
+
+Sometimes it is useful to determine the programs that are to be built
+at configure time. For instance, GNU @code{cpio} only builds
+@code{mt} and @code{rmt} under special circumstances. The means to
+achieve conditional compilation of programs are the same you can use
+to compile source files conditionally: substitutions or conditionals.
+
+@subsubheading Conditional Programs using @command{configure} Substitutions
+
+@vindex EXTRA_PROGRAMS
+@cindex @code{EXTRA_PROGRAMS}, defined
+In this case, you must notify Automake of all the programs that can
+possibly be built, but at the same time cause the generated
+@file{Makefile.in} to use the programs specified by @command{configure}.
+This is done by having @command{configure} substitute values into each
+@code{_PROGRAMS} definition, while listing all optionally built programs
+in @code{EXTRA_PROGRAMS}.
+
+@example
+bin_PROGRAMS = cpio pax $(MT)
+libexec_PROGRAMS = $(RMT)
+EXTRA_PROGRAMS = mt rmt
+@end example
+
+As explained in @ref{EXEEXT}, Automake will rewrite
+@code{bin_PROGRAMS}, @code{libexec_PROGRAMS}, and
+@code{EXTRA_PROGRAMS}, appending @samp{$(EXEEXT)} to each binary.
+Obviously it cannot rewrite values obtained at run-time through
+@command{configure} substitutions, therefore you should take care of
+appending @samp{$(EXEEXT)} yourself, as in @samp{AC_SUBST([MT],
+['mt$@{EXEEXT@}'])}.

+You can also use Automake conditionals (@pxref{Conditionals}) to

+Building a library is much like building a program. In this case, the
+name of the primary is @code{LIBRARIES}. Libraries can be installed in
+@code{libdir} or @code{pkglibdir}.
+
+@xref{A Shared Library}, for information on how to build shared
+libraries using libtool and the @code{LTLIBRARIES} primary.
+
+Each @code{_LIBRARIES} variable is a list of the libraries to be built.
+For instance, to create a library named @file{libcpio.a}, but not install
+it, you would write:
+
+@example
+noinst_LIBRARIES = libcpio.a
+libcpio_a_SOURCES = @dots{}
+@end example
+
+The sources that go into a library are determined exactly as they are
+for programs, via the @code{_SOURCES} variables. Note that the library
+name is canonicalized (@pxref{Canonicalization}), so the @code{_SOURCES}
+variable corresponding to @file{libcpio.a} is @samp{libcpio_a_SOURCES},
+not @samp{libcpio.a_SOURCES}.
+
+@vindex maude_LIBADD
+Extra objects can be added to a library using the
+@code{@var{library}_LIBADD} variable. This should be used for objects
+determined by @command{configure}. Again from @code{cpio}:
+
+@c Keep in sync with pr401c.sh
+@example
+libcpio_a_LIBADD = $(LIBOBJS) $(ALLOCA)
+@end example
+
+In addition, sources for extra objects that will not exist until
+configure-time must be added to the @code{BUILT_SOURCES} variable
+(@pxref{Sources}).
+
+Building a static library is done by compiling all object files, then
+by invoking @samp{$(AR) $(ARFLAGS)} followed by the name of the
+library and the list of objects, and finally by calling
+@samp{$(RANLIB)} on that library. You should call
+@code{AC_PROG_RANLIB} from your @file{configure.ac} to define
+@code{RANLIB} (Automake will complain otherwise). You should also
+call @code{AM_PROG_AR} to define @code{AR}, in order to support unusual
+archivers such as Microsoft lib. @code{ARFLAGS} will default to
+@code{cru}; you can override this variable by setting it in your
+@file{Makefile.am} or by @code{AC_SUBST}ing it from your
+@file{configure.ac}. You can override the @code{AR} variable by
+defining a per-library @code{maude_AR} variable (@pxref{Program and
+Library Variables}).
+
+@cindex Empty libraries
+Be careful when selecting library components conditionally. Because
+building an empty library is not portable, you should ensure that any
+library always contains at least one object.
+
+To use a static library when building a program, add it to
+@code{LDADD} for this program. In the following example, the program
+@file{cpio} is statically linked with the library @file{libcpio.a}.
+
+@example
+noinst_LIBRARIES = libcpio.a
+libcpio_a_SOURCES = @dots{}
+
+bin_PROGRAMS = cpio
+cpio_SOURCES = cpio.c @dots{}
+cpio_LDADD = libcpio.a

+
+@cindex @command{libtool}, introduction
+@cindex libtool library, definition
+@cindex suffix @file{.la}, defined
+@cindex @file{.la} suffix, defined
+
+Libtool abstracts shared and static libraries into a unified concept
+henceforth called @dfn{libtool libraries}. Libtool libraries are
+files using the @file{.la} suffix, and can designate a static library,
+a shared library, or maybe both. Their exact nature cannot be
+determined until @file{./configure} is run: not all platforms support
+all kinds of libraries, and users can explicitly select which
+libraries should be built. (However the package's maintainers can
+tune the default, @pxref{AC_PROG_LIBTOOL, , The @code{AC_PROG_LIBTOOL}
+macro, libtool, The Libtool Manual}.)
+
+@cindex suffix @file{.lo}, defined
+Because object files for shared and static libraries must be compiled
+differently, libtool is also used during compilation. Object files
+built by libtool are called @dfn{libtool objects}: these are files
+using the @file{.lo} suffix. Libtool libraries are built from these
+libtool objects.
+
+You should not assume anything about the structure of @file{.la} or
+@file{.lo} files and how libtool constructs them: this is libtool's
+concern, and the last thing one wants is to learn about libtool's
+guts. However the existence of these files matters, because they are
+used as targets and dependencies in @file{Makefile}s rules when
+building libtool libraries. There are situations where you may have
+to refer to these, for instance when expressing dependencies for
+building source files conditionally (@pxref{Conditional Libtool
+Sources}).
+
+@cindex @file{libltdl}, introduction
+
+People considering writing a plug-in system, with dynamically loaded
+modules, should look into @file{libltdl}: libtool's dlopening library
+(@pxref{Using libltdl, , Using libltdl, libtool, The Libtool Manual}).
+This offers a portable dlopening facility to load libtool libraries
+dynamically, and can also achieve static linking where unavoidable.
+
+Before we discuss how to use libtool with Automake in details, it
+should be noted that the libtool manual also has a section about how
+to use Automake with libtool (@pxref{Using Automake, , Using Automake
+with Libtool, libtool, The Libtool Manual}).

+@vindex pkglib_LTLIBRARIES
+@vindex _LTLIBRARIES
+
+Automake uses libtool to build libraries declared with the
+@code{LTLIBRARIES} primary. Each @code{_LTLIBRARIES} variable is a
+list of libtool libraries to build. For instance, to create a libtool
+library named @file{libgettext.la}, and install it in @code{libdir},
+write:
+
+@example
+lib_LTLIBRARIES = libgettext.la
+libgettext_la_SOURCES = gettext.c gettext.h @dots{}
+@end example
+
+Automake predefines the variable @code{pkglibdir}, so you can use
+@code{pkglib_LTLIBRARIES} to install libraries in
+@samp{$(libdir)/@@PACKAGE@@/}.
+
+If @file{gettext.h} is a public header file that needs to be installed
+in order for people to use the library, it should be declared using a
+@code{_HEADERS} variable, not in @code{libgettext_la_SOURCES}.
+Headers listed in the latter should be internal headers that are not
+part of the public interface.
+
+@example
+lib_LTLIBRARIES = libgettext.la
+libgettext_la_SOURCES = gettext.c @dots{}
+include_HEADERS = gettext.h @dots{}
+@end example
+
+A package can build and install such a library along with other
+programs that use it. This dependency should be specified using
+@code{LDADD}. The following example builds a program named
+@file{hello} that is linked with @file{libgettext.la}.
+
+@example
+lib_LTLIBRARIES = libgettext.la
+libgettext_la_SOURCES = gettext.c @dots{}
+
+bin_PROGRAMS = hello
+hello_SOURCES = hello.c @dots{}
+hello_LDADD = libgettext.la
+@end example
+
+@noindent
+Whether @file{hello} is statically or dynamically linked with
+@file{libgettext.la} is not yet known: this will depend on the
+configuration of libtool and the capabilities of the host.
+
+
+@node Conditional Libtool Libraries
+@subsection Building Libtool Libraries Conditionally
+@cindex libtool libraries, conditional
+@cindex conditional libtool libraries
+
+Like conditional programs (@pxref{Conditional Programs}), there are
+two main ways to build conditional libraries: using Automake
+conditionals or using Autoconf @code{AC_SUBST}itutions.
+
+The important implementation detail you have to be aware of is that
+the place where a library will be installed matters to libtool: it
+needs to be indicated @emph{at link-time} using the @option{-rpath}
+option.
+
+For libraries whose destination directory is known when Automake runs,
+Automake will automatically supply the appropriate @option{-rpath}
+option to libtool. This is the case for libraries listed explicitly in
+some installable @code{_LTLIBRARIES} variables such as
+@code{lib_LTLIBRARIES}.
+
+However, for libraries determined at configure time (and thus
+mentioned in @code{EXTRA_LTLIBRARIES}), Automake does not know the
+final installation directory. For such libraries you must add the
+@option{-rpath} option to the appropriate @code{_LDFLAGS} variable by
+hand.
+
+The examples below illustrate the differences between these two methods.
+
+Here is an example where @code{WANTEDLIBS} is an @code{AC_SUBST}ed
+variable set at @file{./configure}-time to either @file{libfoo.la},
+@file{libbar.la}, both, or none. Although @samp{$(WANTEDLIBS)}
+appears in the @code{lib_LTLIBRARIES}, Automake cannot guess it
+relates to @file{libfoo.la} or @file{libbar.la} at the time it creates
+the link rule for these two libraries. Therefore the @option{-rpath}
+argument must be explicitly supplied.
+
+@c Keep in sync with ltcond.sh
+@example
+EXTRA_LTLIBRARIES = libfoo.la libbar.la
+lib_LTLIBRARIES = $(WANTEDLIBS)
+libfoo_la_SOURCES = foo.c @dots{}
+libfoo_la_LDFLAGS = -rpath '$(libdir)'
+libbar_la_SOURCES = bar.c @dots{}
+libbar_la_LDFLAGS = -rpath '$(libdir)'
+@end example
+
+Here is how the same @file{Makefile.am} would look using Automake
+conditionals named @code{WANT_LIBFOO} and @code{WANT_LIBBAR}. Now
+Automake is able to compute the @option{-rpath} setting itself, because
+it's clear that both libraries will end up in @samp{$(libdir)} if they
+are installed.
+
+@c Keep in sync with ltcond.sh
+@example
+lib_LTLIBRARIES =
+if WANT_LIBFOO
+lib_LTLIBRARIES += libfoo.la
+endif
+if WANT_LIBBAR
+lib_LTLIBRARIES += libbar.la
+endif
+libfoo_la_SOURCES = foo.c @dots{}
+libbar_la_SOURCES = bar.c @dots{}
+@end example
+
+@node Conditional Libtool Sources
+@subsection Libtool Libraries with Conditional Sources
+
+Conditional compilation of sources in a library can be achieved in the
+same way as conditional compilation of sources in a program
+(@pxref{Conditional Sources}). The only difference is that
+@code{_LIBADD} should be used instead of @code{_LDADD} and that it
+should mention libtool objects (@file{.lo} files).
+
+So, to mimic the @file{hello} example from @ref{Conditional Sources},
+we could build a @file{libhello.la} library using either
+@file{hello-linux.c} or @file{hello-generic.c} with the following
+@file{Makefile.am}.
+
+@c Keep in sync with ltcond2.sh
+@example
+lib_LTLIBRARIES = libhello.la
+libhello_la_SOURCES = hello-common.c
+EXTRA_libhello_la_SOURCES = hello-linux.c hello-generic.c
+libhello_la_LIBADD = $(HELLO_SYSTEM)
+libhello_la_DEPENDENCIES = $(HELLO_SYSTEM)
+@end example
+
+@noindent
+And make sure @command{configure} defines @code{HELLO_SYSTEM} as
+either @file{hello-linux.lo} or @file{hello-@-generic.lo}.
+
+Or we could simply use an Automake conditional as follows.
+
+@c Keep in sync with ltcond2.sh
+@example
+lib_LTLIBRARIES = libhello.la
+libhello_la_SOURCES = hello-common.c
+if LINUX
+libhello_la_SOURCES += hello-linux.c
+else
+libhello_la_SOURCES += hello-generic.c

+@node Libtool Convenience Libraries
+@subsection Libtool Convenience Libraries
+@cindex convenience libraries, libtool
+@cindex libtool convenience libraries
+@vindex noinst_LTLIBRARIES
+@vindex check_LTLIBRARIES
+
+Sometimes you want to build libtool libraries that should not be
+installed. These are called @dfn{libtool convenience libraries} and
+are typically used to encapsulate many sublibraries, later gathered
+into one big installed library.
+
+Libtool convenience libraries are declared by directory-less variables
+such as @code{noinst_LTLIBRARIES}, @code{check_LTLIBRARIES}, or even
+@code{EXTRA_LTLIBRARIES}. Unlike installed libtool libraries they do
+not need an @option{-rpath} flag at link time (actually this is the only
+difference).
+
+Convenience libraries listed in @code{noinst_LTLIBRARIES} are always
+built. Those listed in @code{check_LTLIBRARIES} are built only upon
+@samp{make check}. Finally, libraries listed in
+@code{EXTRA_LTLIBRARIES} are never built explicitly: Automake outputs
+rules to build them, but if the library does not appear as a Makefile
+dependency anywhere it won't be built (this is why
+@code{EXTRA_LTLIBRARIES} is used for conditional compilation).
+
+Here is a sample setup merging libtool convenience libraries from
+subdirectories into one main @file{libtop.la} library.
+
+@c Keep in sync with ltconv.sh
+@example
+# -- Top-level Makefile.am --
+SUBDIRS = sub1 sub2 @dots{}
+lib_LTLIBRARIES = libtop.la
+libtop_la_SOURCES =
+libtop_la_LIBADD = \
+ sub1/libsub1.la \
+ sub2/libsub2.la \
+ @dots{}
+
+# -- sub1/Makefile.am --
+noinst_LTLIBRARIES = libsub1.la
+libsub1_la_SOURCES = @dots{}
+
+# -- sub2/Makefile.am --
+# showing nested convenience libraries
+SUBDIRS = sub2.1 sub2.2 @dots{}
+noinst_LTLIBRARIES = libsub2.la
+libsub2_la_SOURCES =
+libsub2_la_LIBADD = \
+ sub21/libsub21.la \
+ sub22/libsub22.la \
+ @dots{}
+@end example
+
+When using such setup, beware that @command{automake} will assume
+@file{libtop.la} is to be linked with the C linker. This is because
+@code{libtop_la_SOURCES} is empty, so @command{automake} picks C as
+default language. If @code{libtop_la_SOURCES} was not empty,
+@command{automake} would select the linker as explained in @ref{How
+the Linker is Chosen}.
+
+If one of the sublibraries contains non-C source, it is important that
+the appropriate linker be chosen. One way to achieve this is to
+pretend that there is such a non-C file among the sources of the
+library, thus forcing @command{automake} to select the appropriate
+linker. Here is the top-level @file{Makefile} of our example updated
+to force C++ linking.
+
+@example
+SUBDIRS = sub1 sub2 @dots{}
+lib_LTLIBRARIES = libtop.la
+libtop_la_SOURCES =
+# Dummy C++ source to cause C++ linking.
+nodist_EXTRA_libtop_la_SOURCES = dummy.cxx
+libtop_la_LIBADD = \
+ sub1/libsub1.la \
+ sub2/libsub2.la \
+ @dots{}
+@end example
+
+@samp{EXTRA_*_SOURCES} variables are used to keep track of source
+files that might be compiled (this is mostly useful when doing
+conditional compilation using @code{AC_SUBST}, @pxref{Conditional
+Libtool Sources}), and the @code{nodist_} prefix means the listed
+sources are not to be distributed (@pxref{Program and Library
+Variables}). In effect the file @file{dummy.cxx} does not need to
+exist in the source tree. Of course if you have some real source file
+to list in @code{libtop_la_SOURCES} there is no point in cheating with
+@code{nodist_EXTRA_libtop_la_SOURCES}.
+
+
+@node Libtool Modules
+@subsection Libtool Modules
+@cindex modules, libtool
+@cindex libtool modules
+@cindex @option{-module}, libtool
+
+These are libtool libraries meant to be dlopened. They are
+indicated to libtool by passing @option{-module} at link-time.
+
+@example
+pkglib_LTLIBRARIES = mymodule.la
+mymodule_la_SOURCES = doit.c
+mymodule_la_LDFLAGS = -module
+@end example
+
+Ordinarily, Automake requires that a library's name start with
+@code{lib}. However, when building a dynamically loadable module you
+might wish to use a "nonstandard" name. Automake will not complain
+about such nonstandard names if it knows the library being built is a
+libtool module, i.e., if @option{-module} explicitly appears in the
+library's @code{_LDFLAGS} variable (or in the common @code{AM_LDFLAGS}
+variable when no per-library @code{_LDFLAGS} variable is defined).
+
+As always, @code{AC_SUBST} variables are black boxes to Automake since
+their values are not yet known when @command{automake} is run.
+Therefore if @option{-module} is set via such a variable, Automake
+cannot notice it and will proceed as if the library was an ordinary
+libtool library, with strict naming.
+
+If @code{mymodule_la_SOURCES} is not specified, then it defaults to
+the single file @file{mymodule.c} (@pxref{Default _SOURCES}).

+
+As shown in previous sections, the @samp{@var{library}_LIBADD}
+variable should be used to list extra libtool objects (@file{.lo}
+files) or libtool libraries (@file{.la}) to add to @var{library}.
+
+The @samp{@var{library}_LDFLAGS} variable is the place to list
+additional libtool linking flags, such as @option{-version-info},
+@option{-static}, and a lot more. @xref{Link mode, , Link mode,
+libtool, The Libtool Manual}.
+
+The @command{libtool} command has two kinds of options: mode-specific
+options and generic options. Mode-specific options such as the
+aforementioned linking flags should be lumped with the other flags
+passed to the tool invoked by @command{libtool} (hence the use of
+@samp{@var{library}_LDFLAGS} for libtool linking flags). Generic
+options include @option{--tag=@var{tag}} and @option{--silent}
+(@pxref{Invoking libtool, , Invoking @command{libtool}, libtool, The
+Libtool Manual} for more options) should appear before the mode
+selection on the command line; in @file{Makefile.am}s they should
+be listed in the @samp{@var{library}_LIBTOOLFLAGS} variable.
+
+If @samp{@var{library}_LIBTOOLFLAGS} is not defined, then the variable
+@code{AM_LIBTOOLFLAGS} is used instead.
+
+These flags are passed to libtool after the @option{--tag=@var{tag}}
+option computed by Automake (if any), so
+@samp{@var{library}_LIBTOOLFLAGS} (or @code{AM_LIBTOOLFLAGS}) is a
+good place to override or supplement the @option{--tag=@var{tag}}
+setting.
+
+The libtool rules also use a @code{LIBTOOLFLAGS} variable that should
+not be set in @file{Makefile.am}: this is a user variable (@pxref{Flag
+Variables Ordering}. It allows users to run @samp{make
+LIBTOOLFLAGS=--silent}, for instance. Note that the verbosity of
+@command{libtool} can also be influenced with the Automake
+@option{silent-rules} option (@pxref{Options}).

+Libtool comes with a tool called @command{libtoolize} that will

+command will install @file{ltmain.sh}. You should execute it before
+@command{aclocal} and @command{automake}.
+
+People upgrading old packages to newer autotools are likely to face
+this issue because older Automake versions used to call
+@command{libtoolize}. Therefore old build scripts do not call
+@command{libtoolize}.
+
+Since Automake 1.6, it has been decided that running
+@command{libtoolize} was none of Automake's business. Instead, that
+functionality has been moved into the @command{autoreconf} command
+(@pxref{autoreconf Invocation, , Using @command{autoreconf}, autoconf,

+when, just learn the @command{autoreconf} command. Hopefully,

+
+@node Objects created both with libtool and without
+@subsubsection Objects @samp{created with both libtool and without}
+
+Sometimes, the same source file is used both to build a libtool
+library and to build another non-libtool target (be it a program or
+another library).
+
+Let's consider the following @file{Makefile.am}.
+
+@example
+bin_PROGRAMS = prog
+prog_SOURCES = prog.c foo.c @dots{}
+
+lib_LTLIBRARIES = libfoo.la
+libfoo_la_SOURCES = foo.c @dots{}
+@end example
+
+@noindent
+(In this trivial case the issue could be avoided by linking
+@file{libfoo.la} with @file{prog} instead of listing @file{foo.c} in
+@code{prog_SOURCES}. But let's assume we really want to keep
+@file{prog} and @file{libfoo.la} separate.)
+
+Technically, it means that we should build @file{foo.$(OBJEXT)} for
+@file{prog}, and @file{foo.lo} for @file{libfoo.la}. The problem is
+that in the course of creating @file{foo.lo}, libtool may erase (or
+replace) @file{foo.$(OBJEXT)}, and this cannot be avoided.
+
+Therefore, when Automake detects this situation it will complain
+with a message such as
+@example
+object `foo.$(OBJEXT)' created both with libtool and without
+@end example
+
+A workaround for this issue is to ensure that these two objects get
+different basenames. As explained in @ref{Renamed Objects}, this
+happens automatically when per-targets flags are used.
+
+@example
+bin_PROGRAMS = prog
+prog_SOURCES = prog.c foo.c @dots{}
+prog_CFLAGS = $(AM_CFLAGS)
+
+lib_LTLIBRARIES = libfoo.la
+libfoo_la_SOURCES = foo.c @dots{}
+@end example
+
+@noindent
+Adding @samp{prog_CFLAGS = $(AM_CFLAGS)} is almost a no-op, because
+when the @code{prog_CFLAGS} is defined, it is used instead of
+@code{AM_CFLAGS}. However as a side effect it will cause
+@file{prog.c} and @file{foo.c} to be compiled as
+@file{prog-prog.$(OBJEXT)} and @file{prog-foo.$(OBJEXT)}, which solves
+the issue.
+
+@node Program and Library Variables
+@section Program and Library Variables
+
+Associated with each program is a collection of variables that can be
+used to modify how that program is built. There is a similar list of
+such variables for each library. The canonical name of the program (or
+library) is used as a base for naming these variables.
+
+In the list below, we use the name ``maude'' to refer to the program or
+library. In your @file{Makefile.am} you would replace this with the
+canonical name of your program. This list also refers to ``maude'' as a
+program, but in general the same rules apply for both static and dynamic
+libraries; the documentation below notes situations where programs and
+libraries differ.
+
+@vtable @code
+@item maude_SOURCES
+This variable, if it exists, lists all the source files that are
+compiled to build the program. These files are added to the
+distribution by default. When building the program, Automake will cause
+each source file to be compiled to a single @file{.o} file (or
+@file{.lo} when using libtool). Normally these object files are named
+after the source file, but other factors can change this. If a file in
+the @code{_SOURCES} variable has an unrecognized extension, Automake
+will do one of two things with it. If a suffix rule exists for turning
+files with the unrecognized extension into @file{.o} files, then
+@command{automake} will treat this file as it will any other source file
+(@pxref{Support for Other Languages}). Otherwise, the file will be
+ignored as though it were a header file.
+
+The prefixes @code{dist_} and @code{nodist_} can be used to control
+whether files listed in a @code{_SOURCES} variable are distributed.
+@code{dist_} is redundant, as sources are distributed by default, but it
+can be specified for clarity if desired.
+
+It is possible to have both @code{dist_} and @code{nodist_} variants of
+a given @code{_SOURCES} variable at once; this lets you easily
+distribute some files and not others, for instance:
+
+@example
+nodist_maude_SOURCES = nodist.c
+dist_maude_SOURCES = dist-me.c
+@end example
+
+By default the output file (on Unix systems, the @file{.o} file) will
+be put into the current build directory. However, if the option
+@option{subdir-objects} is in effect in the current directory then the
+@file{.o} file will be put into the subdirectory named after the
+source file. For instance, with @option{subdir-objects} enabled,
+@file{sub/dir/file.c} will be compiled to @file{sub/dir/file.o}. Some
+people prefer this mode of operation. You can specify
+@option{subdir-objects} in @code{AUTOMAKE_OPTIONS} (@pxref{Options}).
+@cindex Subdirectory, objects in
+@cindex Objects in subdirectory
+
+
+@item EXTRA_maude_SOURCES
+Automake needs to know the list of files you intend to compile
+@emph{statically}. For one thing, this is the only way Automake has of
+knowing what sort of language support a given @file{Makefile.in}
+requires. @footnote{There are other, more obscure reasons for
+this limitation as well.} This means that, for example, you can't put a
+configure substitution like @samp{@@my_sources@@} into a @samp{_SOURCES}
+variable. If you intend to conditionally compile source files and use
+@file{configure} to substitute the appropriate object names into, e.g.,
+@code{_LDADD} (see below), then you should list the corresponding source
+files in the @code{EXTRA_} variable.
+
+This variable also supports @code{dist_} and @code{nodist_} prefixes.
+For instance, @code{nodist_EXTRA_maude_SOURCES} would list extra
+sources that may need to be built, but should not be distributed.
+
+@item maude_AR
+A static library is created by default by invoking @samp{$(AR)
+$(ARFLAGS)} followed by the name of the library and then the objects
+being put into the library. You can override this by setting the
+@code{_AR} variable. This is usually used with C++; some C++
+compilers require a special invocation in order to instantiate all the
+templates that should go into a library. For instance, the SGI C++
+compiler likes this variable set like so:
+@example
+libmaude_a_AR = $(CXX) -ar -o
+@end example
+
+@item maude_LIBADD
+Extra objects can be added to a @emph{library} using the @code{_LIBADD}
+variable. For instance, this should be used for objects determined by
+@command{configure} (@pxref{A Library}).
+
+In the case of libtool libraries, @code{maude_LIBADD} can also refer
+to other libtool libraries.
+
+@item maude_LDADD
+Extra objects (@file{*.$(OBJEXT)}) and libraries (@file{*.a},
+@file{*.la}) can be added to a @emph{program} by listing them in the
+@code{_LDADD} variable. For instance, this should be used for objects
+determined by @command{configure} (@pxref{Linking}).
+
+@code{_LDADD} and @code{_LIBADD} are inappropriate for passing
+program-specific linker flags (except for @option{-l}, @option{-L},
+@option{-dlopen} and @option{-dlpreopen}). Use the @code{_LDFLAGS} variable
+for this purpose.
+
+For instance, if your @file{configure.ac} uses @code{AC_PATH_XTRA}, you
+could link your program against the X libraries like so:
+
+@example
+maude_LDADD = $(X_PRE_LIBS) $(X_LIBS) $(X_EXTRA_LIBS)
+@end example
+
+We recommend that you use @option{-l} and @option{-L} only when
+referring to third-party libraries, and give the explicit file names
+of any library built by your package. Doing so will ensure that
+@code{maude_DEPENDENCIES} (see below) is correctly defined by default.
+
+@item maude_LDFLAGS
+This variable is used to pass extra flags to the link step of a program
+or a shared library. It overrides the @code{AM_LDFLAGS} variable.
+
+@item maude_LIBTOOLFLAGS
+This variable is used to pass extra options to @command{libtool}.
+It overrides the @code{AM_LIBTOOLFLAGS} variable.
+These options are output before @command{libtool}'s @option{--mode=@var{mode}}
+option, so they should not be mode-specific options (those belong to
+the compiler or linker flags). @xref{Libtool Flags}.
+
+@item maude_DEPENDENCIES
+@itemx EXTRA_maude_DEPENDENCIES
+It is also occasionally useful to have a target (program or library)
+depend on some other file that is not actually part of that target.
+This can be done using the @code{_DEPENDENCIES} variable. Each
+target depends on the contents of such a variable, but no further
+interpretation is done.
+
+Since these dependencies are associated to the link rule used to
+create the programs they should normally list files used by the link
+command. That is @file{*.$(OBJEXT)}, @file{*.a}, or @file{*.la} files
+for programs; @file{*.lo} and @file{*.la} files for Libtool libraries;
+and @file{*.$(OBJEXT)} files for static libraries. In rare cases you
+may need to add other kinds of files such as linker scripts, but
+@emph{listing a source file in @code{_DEPENDENCIES} is wrong}. If
+some source file needs to be built before all the components of a
+program are built, consider using the @code{BUILT_SOURCES} variable
+(@pxref{Sources}).
+
+If @code{_DEPENDENCIES} is not supplied, it is computed by Automake.
+The automatically-assigned value is the contents of @code{_LDADD} or
+@code{_LIBADD}, with most configure substitutions, @option{-l}, @option{-L},
+@option{-dlopen} and @option{-dlpreopen} options removed. The configure
+substitutions that are left in are only @samp{$(LIBOBJS)} and
+@samp{$(ALLOCA)}; these are left because it is known that they will not
+cause an invalid value for @code{_DEPENDENCIES} to be generated.
+
+@code{_DEPENDENCIES} is more likely used to perform conditional
+compilation using an @code{AC_SUBST} variable that contains a list of
+objects. @xref{Conditional Sources}, and @ref{Conditional Libtool
+Sources}.
+
+The @code{EXTRA_*_DEPENDENCIES} variable may be useful for cases where
+you merely want to augment the @command{automake}-generated
+@code{_DEPENDENCIES} variable rather than replacing it.
+
+@item maude_LINK
+You can override the linker on a per-program basis. By default the
+linker is chosen according to the languages used by the program. For
+instance, a program that includes C++ source code would use the C++
+compiler to link. The @code{_LINK} variable must hold the name of a
+command that can be passed all the @file{.o} file names and libraries
+to link against as arguments. Note that the name of the underlying
+program is @emph{not} passed to @code{_LINK}; typically one uses
+@samp{$@@}:
+
+@example
+maude_LINK = $(CCLD) -magic -o $@@
+@end example
+
+If a @code{_LINK} variable is not supplied, it may still be generated
+and used by Automake due to the use of per-target link flags such as
+@code{_CFLAGS}, @code{_LDFLAGS} or @code{_LIBTOOLFLAGS}, in cases where
+they apply.

+@cindex per-target compilation flags, defined
+Automake allows you to set compilation flags on a per-program (or
+per-library) basis. A single source file can be included in several
+programs, and it will potentially be compiled with different flags for
+each program. This works for any language directly supported by
+Automake. These @dfn{per-target compilation flags} are
+@samp{_CCASFLAGS},
+@samp{_CFLAGS},
+@samp{_CPPFLAGS},
+@samp{_CXXFLAGS},
+@samp{_FFLAGS},
+@samp{_GCJFLAGS},
+@samp{_LFLAGS},
+@samp{_OBJCFLAGS},
+@samp{_OBJCXXFLAGS},
+@samp{_RFLAGS},
+@samp{_UPCFLAGS}, and
+@samp{_YFLAGS}.
+
+When using a per-target compilation flag, Automake will choose a
+different name for the intermediate object files. Ordinarily a file
+like @file{sample.c} will be compiled to produce @file{sample.o}.
+However, if the program's @code{_CFLAGS} variable is set, then the
+object file will be named, for instance, @file{maude-sample.o}. (See
+also @ref{Renamed Objects}.) The use of per-target compilation flags
+with C sources requires that the macro @code{AM_PROG_CC_C_O} be called
+from @file{configure.ac}.
+
+In compilations with per-target flags, the ordinary @samp{AM_} form of
+the flags variable is @emph{not} automatically included in the
+compilation (however, the user form of the variable @emph{is} included).
+So for instance, if you want the hypothetical @file{maude} compilations
+to also use the value of @code{AM_CFLAGS}, you would need to write:
+
+@example
+maude_CFLAGS = @dots{} your flags @dots{} $(AM_CFLAGS)
+@end example
+
+@xref{Flag Variables Ordering}, for more discussion about the
+interaction between user variables, @samp{AM_} shadow variables, and
+per-target variables.
+
+@item maude_SHORTNAME
+On some platforms the allowable file names are very short. In order to
+support these systems and per-target compilation flags at the same
+time, Automake allows you to set a ``short name'' that will influence
+how intermediate object files are named. For instance, in the following
+example,
+
+@example
+bin_PROGRAMS = maude
+maude_CPPFLAGS = -DSOMEFLAG
+maude_SHORTNAME = m
+maude_SOURCES = sample.c @dots{}
+@end example
+
+@noindent
+the object file would be named @file{m-sample.o} rather than
+@file{maude-sample.o}.
+
+This facility is rarely needed in practice,
+and we recommend avoiding it until you find it is required.

+@vindex AM_DEFAULT_SOURCE_EXT
+
+@code{_SOURCES} variables are used to specify source files of programs
+(@pxref{A Program}), libraries (@pxref{A Library}), and Libtool
+libraries (@pxref{A Shared Library}).
+
+When no such variable is specified for a target, Automake will define
+one itself. The default is to compile a single C file whose base name
+is the name of the target itself, with any extension replaced by
+@code{AM_DEFAULT_SOURCE_EXT}, which defaults to @file{.c}.
+
+For example if you have the following somewhere in your
+@file{Makefile.am} with no corresponding @code{libfoo_a_SOURCES}:
+
+@example
+lib_LIBRARIES = libfoo.a sub/libc++.a
+@end example
+
+@noindent
+@file{libfoo.a} will be built using a default source file named
+@file{libfoo.c}, and @file{sub/libc++.a} will be built from
+@file{sub/libc++.c}. (In older versions @file{sub/libc++.a}
+would be built from @file{sub_libc___a.c}, i.e., the default source
+was the canonized name of the target, with @file{.c} appended.
+We believe the new behavior is more sensible, but for backward
+compatibility @command{automake} will use the old name if a file or a rule
+with that name exists and @code{AM_DEFAULT_SOURCE_EXT} is not used.)
+
+@cindex @code{check_PROGRAMS} example
+@vindex check_PROGRAMS
+Default sources are mainly useful in test suites, when building many
+test programs each from a single source. For instance, in
+
+@example
+check_PROGRAMS = test1 test2 test3
+AM_DEFAULT_SOURCE_EXT = .cpp
+@end example
+
+@noindent
+@file{test1}, @file{test2}, and @file{test3} will be built
+from @file{test1.cpp}, @file{test2.cpp}, and @file{test3.cpp}.
+Without the last line, they will be built from @file{test1.c},
+@file{test2.c}, and @file{test3.c}.
+
+@cindex Libtool modules, default source example

+Finally, there is one situation where this default source computation

+We already saw such an example in @ref{true}; this happens when all
+the constituents of a target have already been compiled and just need
+to be combined using a @code{_LDADD} variable. Then it is necessary
+to define an empty @code{_SOURCES} variable, so that @command{automake}
+does not compute a default.

+
+The @samp{$(LIBOBJS)} and @samp{$(ALLOCA)} variables list object
+files that should be compiled into the project to provide an
+implementation for functions that are missing or broken on the host
+system. They are substituted by @file{configure}.
+
+@acindex AC_LIBOBJ
+
+These variables are defined by Autoconf macros such as
+@code{AC_LIBOBJ}, @code{AC_REPLACE_FUNCS} (@pxref{Generic Functions, ,
+Generic Function Checks, autoconf, The Autoconf Manual}), or
+@code{AC_FUNC_ALLOCA} (@pxref{Particular Functions, , Particular
+Function Checks, autoconf, The Autoconf Manual}). Many other Autoconf
+macros call @code{AC_LIBOBJ} or @code{AC_REPLACE_FUNCS} to
+populate @samp{$(LIBOBJS)}.
+
+@acindex AC_LIBSOURCE
+
+Using these variables is very similar to doing conditional compilation
+using @code{AC_SUBST} variables, as described in @ref{Conditional
+Sources}. That is, when building a program, @samp{$(LIBOBJS)} and
+@samp{$(ALLOCA)} should be added to the associated @samp{*_LDADD}
+variable, or to the @samp{*_LIBADD} variable when building a library.
+However there is no need to list the corresponding sources in
+@samp{EXTRA_*_SOURCES} nor to define @samp{*_DEPENDENCIES}. Automake
+automatically adds @samp{$(LIBOBJS)} and @samp{$(ALLOCA)} to the
+dependencies, and it will discover the list of corresponding source
+files automatically (by tracing the invocations of the
+@code{AC_LIBSOURCE} Autoconf macros). If you have already defined
+@samp{*_DEPENDENCIES} explicitly for an unrelated reason, then you
+either need to add these variables manually, or use
+@samp{EXTRA_*_DEPENDENCIES} instead of @samp{*_DEPENDENCIES}.
+
+These variables are usually used to build a portability library that
+is linked with all the programs of the project. We now review a
+sample setup. First, @file{configure.ac} contains some checks that
+affect either @code{LIBOBJS} or @code{ALLOCA}.
+
+@example
+# configure.ac
+@dots{}
+AC_CONFIG_LIBOBJ_DIR([lib])
+@dots{}
+AC_FUNC_MALLOC dnl May add malloc.$(OBJEXT) to LIBOBJS
+AC_FUNC_MEMCMP dnl May add memcmp.$(OBJEXT) to LIBOBJS
+AC_REPLACE_FUNCS([strdup]) dnl May add strdup.$(OBJEXT) to LIBOBJS
+AC_FUNC_ALLOCA dnl May add alloca.$(OBJEXT) to ALLOCA
+@dots{}
+AC_CONFIG_FILES([
+ lib/Makefile
+ src/Makefile
+])
+AC_OUTPUT
+@end example
+
+@acindex AC_CONFIG_LIBOBJ_DIR
+
+The @code{AC_CONFIG_LIBOBJ_DIR} tells Autoconf that the source files
+of these object files are to be found in the @file{lib/} directory.
+Automake can also use this information, otherwise it expects the
+source files are to be in the directory where the @samp{$(LIBOBJS)}
+and @samp{$(ALLOCA)} variables are used.
+
+The @file{lib/} directory should therefore contain @file{malloc.c},
+@file{memcmp.c}, @file{strdup.c}, @file{alloca.c}. Here is its
+@file{Makefile.am}:
+
+@example
+# lib/Makefile.am
+
+noinst_LIBRARIES = libcompat.a
+libcompat_a_SOURCES =
+libcompat_a_LIBADD = $(LIBOBJS) $(ALLOCA)
+@end example
+
+The library can have any name, of course, and anyway it is not going
+to be installed: it just holds the replacement versions of the missing
+or broken functions so we can later link them in. Many projects
+also include extra functions, specific to the project, in that
+library: they are simply added on the @code{_SOURCES} line.
+
+@cindex Empty libraries and @samp{$(LIBOBJS)}
+@cindex @samp{$(LIBOBJS)} and empty libraries
+There is a small trap here, though: @samp{$(LIBOBJS)} and
+@samp{$(ALLOCA)} might be empty, and building an empty library is not
+portable. You should ensure that there is always something to put in
+@file{libcompat.a}. Most projects will also add some utility
+functions in that directory, and list them in
+@code{libcompat_a_SOURCES}, so in practice @file{libcompat.a} cannot
+be empty.
+
+Finally here is how this library could be used from the @file{src/}
+directory.
+
+@example
+# src/Makefile.am
+
+# Link all programs in this directory with libcompat.a
+LDADD = ../lib/libcompat.a
+
+bin_PROGRAMS = tool1 tool2 @dots{}
+tool1_SOURCES = @dots{}
+tool2_SOURCES = @dots{}
+@end example
+
+When option @option{subdir-objects} is not used, as in the above
+example, the variables @samp{$(LIBOBJS)} or @samp{$(ALLOCA)} can only
+be used in the directory where their sources lie. E.g., here it would
+be wrong to use @samp{$(LIBOBJS)} or @samp{$(ALLOCA)} in
+@file{src/Makefile.am}. However if both @option{subdir-objects} and
+@code{AC_CONFIG_LIBOBJ_DIR} are used, it is OK to use these variables
+in other directories. For instance @file{src/Makefile.am} could be
+changed as follows.
+
+@example
+# src/Makefile.am
+
+AUTOMAKE_OPTIONS = subdir-objects
+LDADD = $(LIBOBJS) $(ALLOCA)
+
+bin_PROGRAMS = tool1 tool2 @dots{}
+tool1_SOURCES = @dots{}
+tool2_SOURCES = @dots{}
+@end example
+
+Because @samp{$(LIBOBJS)} and @samp{$(ALLOCA)} contain object
+file names that end with @samp{.$(OBJEXT)}, they are not suitable for
+Libtool libraries (where the expected object extension is @file{.lo}):
+@code{LTLIBOBJS} and @code{LTALLOCA} should be used instead.
+
+@code{LTLIBOBJS} is defined automatically by Autoconf and should not
+be defined by hand (as in the past), however at the time of writing
+@code{LTALLOCA} still needs to be defined from @code{ALLOCA} manually.

+@node Program Variables
+@section Variables used when building a program
+
+Occasionally it is useful to know which @file{Makefile} variables
+Automake uses for compilations, and in which order (@pxref{Flag
+Variables Ordering}); for instance, you might need to do your own
+compilation in some special cases.
+
+Some variables are inherited from Autoconf; these are @code{CC},
+@code{CFLAGS}, @code{CPPFLAGS}, @code{DEFS}, @code{LDFLAGS}, and
+@code{LIBS}.
+@vindex CC
+@vindex CFLAGS
+@vindex CPPFLAGS
+@vindex DEFS
+@vindex LDFLAGS
+@vindex LIBS
+
+There are some additional variables that Automake defines on its own:
+
+@vtable @code
+@item AM_CPPFLAGS
+The contents of this variable are passed to every compilation that invokes
+the C preprocessor; it is a list of arguments to the preprocessor. For
+instance, @option{-I} and @option{-D} options should be listed here.
+
+Automake already provides some @option{-I} options automatically, in a
+separate variable that is also passed to every compilation that invokes
+the C preprocessor. In particular it generates @samp{-I.},
+@samp{-I$(srcdir)}, and a @option{-I} pointing to the directory holding
+@file{config.h} (if you've used @code{AC_CONFIG_HEADERS} or
+@code{AM_CONFIG_HEADER}). You can disable the default @option{-I}
+options using the @option{nostdinc} option.
+
+When a file to be included is generated during the build and not part
+of a distribution tarball, its location is under @code{$(builddir)},
+not under @code{$(srcdir)}. This matters especially for packages that
+use header files placed in sub-directories and want to allow builds
+outside the source tree (@pxref{VPATH Builds}). In that case we
+recommend to use a pair of @option{-I} options, such as, e.g.,
+@samp{-Isome/subdir -I$(srcdir)/some/subdir} or
+@samp{-I$(top_builddir)/some/subdir -I$(top_srcdir)/some/subdir}.
+Note that the reference to the build tree should come before the
+reference to the source tree, so that accidentally leftover generated
+files in the source directory are ignored.
+
+@code{AM_CPPFLAGS} is ignored in preference to a per-executable (or
+per-library) @code{_CPPFLAGS} variable if it is defined.
+
+@item INCLUDES
+This does the same job as @code{AM_CPPFLAGS} (or any per-target
+@code{_CPPFLAGS} variable if it is used). It is an older name for the
+same functionality. This variable is deprecated; we suggest using
+@code{AM_CPPFLAGS} and per-target @code{_CPPFLAGS} instead.
+
+@item AM_CFLAGS
+This is the variable the @file{Makefile.am} author can use to pass
+in additional C compiler flags. It is more fully documented elsewhere.
+In some situations, this is not used, in preference to the
+per-executable (or per-library) @code{_CFLAGS}.
+
+@item COMPILE
+This is the command used to actually compile a C source file. The
+file name is appended to form the complete command line.
+
+@item AM_LDFLAGS
+This is the variable the @file{Makefile.am} author can use to pass
+in additional linker flags. In some situations, this is not used, in
+preference to the per-executable (or per-library) @code{_LDFLAGS}.
+
+@item LINK
+This is the command used to actually link a C program. It already
+includes @samp{-o $@@} and the usual variable references (for instance,
+@code{CFLAGS}); it takes as ``arguments'' the names of the object files
+and libraries to link in. This variable is not used when the linker is
+overridden with a per-target @code{_LINK} variable or per-target flags
+cause Automake to define such a @code{_LINK} variable.
+@end vtable
+
+
+@node Yacc and Lex
+@section Yacc and Lex support
+
+Automake has somewhat idiosyncratic support for Yacc and Lex.
+
+Automake assumes that the @file{.c} file generated by @command{yacc}
+(or @command{lex}) should be named using the basename of the input
+file. That is, for a yacc source file @file{foo.y}, Automake will
+cause the intermediate file to be named @file{foo.c} (as opposed to
+@file{y.tab.c}, which is more traditional).
+
+The extension of a yacc source file is used to determine the extension
+of the resulting C or C++ source and header files. Note that header
+files are generated only when the @option{-d} Yacc option is used; see
+below for more information about this flag, and how to specify it.
+Files with the extension @file{.y} will thus be turned into @file{.c}
+sources and @file{.h} headers; likewise, @file{.yy} will become
+@file{.cc} and @file{.hh}, @file{.y++} will become @file{c++} and
+@file{h++}, @file{.yxx} will become @file{.cxx} and @file{.hxx},
+and @file{.ypp} will become @file{.cpp} and @file{.hpp}.
+
+Similarly, lex source files can be used to generate C or C++; the
+extensions @file{.l}, @file{.ll}, @file{.l++}, @file{.lxx}, and
+@file{.lpp} are recognized.
+
+You should never explicitly mention the intermediate (C or C++) file
+in any @code{SOURCES} variable; only list the source file.
+
+The intermediate files generated by @command{yacc} (or @command{lex})
+will be included in any distribution that is made. That way the user
+doesn't need to have @command{yacc} or @command{lex}.
+
+If a @command{yacc} source file is seen, then your @file{configure.ac} must
+define the variable @code{YACC}. This is most easily done by invoking
+the macro @code{AC_PROG_YACC} (@pxref{Particular Programs, , Particular
+Program Checks, autoconf, The Autoconf Manual}).
+
+@vindex YFLAGS
+@vindex AM_YFLAGS
+When @code{yacc} is invoked, it is passed @code{AM_YFLAGS} and
+@code{YFLAGS}. The latter is a user variable and the former is
+intended for the @file{Makefile.am} author.
+
+@code{AM_YFLAGS} is usually used to pass the @option{-d} option to
+@command{yacc}. Automake knows what this means and will automatically
+adjust its rules to update and distribute the header file built by
+@samp{yacc -d}@footnote{Please note that @command{automake} recognizes
+@option{-d} in @code{AM_YFLAGS} only if it is not clustered with other
+options; for example, it won't be recognized if @code{AM_YFLAGS} is
+@option{-dt}, but it will be if @code{AM_YFLAGS} is @option{-d -t} or
+@option{-t -d}.}.
+What Automake cannot guess, though, is where this
+header will be used: it is up to you to ensure the header gets built
+before it is first used. Typically this is necessary in order for
+dependency tracking to work when the header is included by another
+file. The common solution is listing the header file in
+@code{BUILT_SOURCES} (@pxref{Sources}) as follows.
+
+@example
+BUILT_SOURCES = parser.h
+AM_YFLAGS = -d
+bin_PROGRAMS = foo
+foo_SOURCES = @dots{} parser.y @dots{}
+@end example
+
+If a @command{lex} source file is seen, then your @file{configure.ac}
+must define the variable @code{LEX}. You can use @code{AC_PROG_LEX}
+to do this (@pxref{Particular Programs, , Particular Program Checks,
+autoconf, The Autoconf Manual}), but using @code{AM_PROG_LEX} macro
+(@pxref{Macros}) is recommended.
+
+@vindex LFLAGS
+@vindex AM_LFLAGS
+When @command{lex} is invoked, it is passed @code{AM_LFLAGS} and
+@code{LFLAGS}. The latter is a user variable and the former is
+intended for the @file{Makefile.am} author.
+
+When @code{AM_MAINTAINER_MODE} (@pxref{maintainer-mode}) is used, the
+rebuild rule for distributed Yacc and Lex sources are only used when
+@code{maintainer-mode} is enabled, or when the files have been erased.
+
+@cindex @command{ylwrap}
+@cindex @command{yacc}, multiple parsers
+@cindex Multiple @command{yacc} parsers
+@cindex Multiple @command{lex} lexers
+@cindex @command{lex}, multiple lexers
+
+When @command{lex} or @command{yacc} sources are used, @code{automake
+-i} automatically installs an auxiliary program called
+@command{ylwrap} in your package (@pxref{Auxiliary Programs}). This
+program is used by the build rules to rename the output of these
+tools, and makes it possible to include multiple @command{yacc} (or
+@command{lex}) source files in a single directory. (This is necessary
+because yacc's output file name is fixed, and a parallel make could
+conceivably invoke more than one instance of @command{yacc}
+simultaneously.)
+
+For @command{yacc}, simply managing locking is insufficient. The output of
+@command{yacc} always uses the same symbol names internally, so it isn't
+possible to link two @command{yacc} parsers into the same executable.
+
+We recommend using the following renaming hack used in @command{gdb}:
+@example
+#define yymaxdepth c_maxdepth
+#define yyparse c_parse
+#define yylex c_lex
+#define yyerror c_error
+#define yylval c_lval
+#define yychar c_char
+#define yydebug c_debug
+#define yypact c_pact
+#define yyr1 c_r1
+#define yyr2 c_r2
+#define yydef c_def
+#define yychk c_chk
+#define yypgo c_pgo
+#define yyact c_act
+#define yyexca c_exca
+#define yyerrflag c_errflag
+#define yynerrs c_nerrs
+#define yyps c_ps
+#define yypv c_pv
+#define yys c_s
+#define yy_yys c_yys
+#define yystate c_state
+#define yytmp c_tmp
+#define yyv c_v
+#define yy_yyv c_yyv
+#define yyval c_val
+#define yylloc c_lloc
+#define yyreds c_reds
+#define yytoks c_toks
+#define yylhs c_yylhs
+#define yylen c_yylen
+#define yydefred c_yydefred
+#define yydgoto c_yydgoto
+#define yysindex c_yysindex
+#define yyrindex c_yyrindex
+#define yygindex c_yygindex
+#define yytable c_yytable
+#define yycheck c_yycheck
+#define yyname c_yyname
+#define yyrule c_yyrule
+@end example
+
+For each define, replace the @samp{c_} prefix with whatever you like.
+These defines work for @command{bison}, @command{byacc}, and
+traditional @code{yacc}s. If you find a parser generator that uses a
+symbol not covered here, please report the new name so it can be added
+to the list.

+@cindex Mixing Fortran 77 with C and/or C++
+
+Automake currently provides @emph{limited} support for creating programs
+and shared libraries that are a mixture of Fortran 77 and C and/or C++.
+However, there are many other issues related to mixing Fortran 77 with
+other languages that are @emph{not} (currently) handled by Automake, but
+that are handled by other packages@footnote{For example,
+@uref{http://www-zeus.desy.de/~burow/cfortran/, the cfortran package}
+addresses all of these inter-language issues, and runs under nearly all
+Fortran 77, C and C++ compilers on nearly all platforms. However,
+@command{cfortran} is not yet Free Software, but it will be in the next
+major release.}.
+
+Automake can help in two ways:
+
+@enumerate
+@item
+Automatic selection of the linker depending on which combinations of
+source code.
+
+@item
+Automatic selection of the appropriate linker flags (e.g., @option{-L} and
+@option{-l}) to pass to the automatically selected linker in order to link
+in the appropriate Fortran 77 intrinsic and run-time libraries.
+
+@cindex @code{FLIBS}, defined
+@vindex FLIBS
+These extra Fortran 77 linker flags are supplied in the output variable
+@code{FLIBS} by the @code{AC_F77_LIBRARY_LDFLAGS} Autoconf macro.
+@xref{Fortran Compiler, , Fortran Compiler Characteristics, autoconf,
+The Autoconf Manual}.
+@end enumerate
+
+If Automake detects that a program or shared library (as mentioned in
+some @code{_PROGRAMS} or @code{_LTLIBRARIES} primary) contains source
+code that is a mixture of Fortran 77 and C and/or C++, then it requires
+that the macro @code{AC_F77_LIBRARY_LDFLAGS} be called in
+@file{configure.ac}, and that either @code{$(FLIBS)}
+appear in the appropriate @code{_LDADD} (for programs) or @code{_LIBADD}
+(for shared libraries) variables. It is the responsibility of the
+person writing the @file{Makefile.am} to make sure that @samp{$(FLIBS)}
+appears in the appropriate @code{_LDADD} or
+@code{_LIBADD} variable.
+
+@cindex Mixed language example
+@cindex Example, mixed language
+
+For example, consider the following @file{Makefile.am}:
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = main.cc foo.f
+foo_LDADD = libfoo.la $(FLIBS)
+
+pkglib_LTLIBRARIES = libfoo.la
+libfoo_la_SOURCES = bar.f baz.c zardoz.cc
+libfoo_la_LIBADD = $(FLIBS)
+@end example
+
+In this case, Automake will insist that @code{AC_F77_LIBRARY_LDFLAGS}
+is mentioned in @file{configure.ac}. Also, if @samp{$(FLIBS)} hadn't
+been mentioned in @code{foo_LDADD} and @code{libfoo_la_LIBADD}, then
+Automake would have issued a warning.

+@subsubsection How the Linker is Chosen
+
+@cindex Automatic linker selection

+
+When a program or library mixes several languages, Automake choose the
+linker according to the following priorities. (The names in
+parentheses are the variables containing the link command.)
+
+@enumerate
+@item
+@vindex GCJLINK

+@item
+@vindex UPCLINK
+Unified Parallel C (@code{UPCLINK})
+@item
+@vindex LINK
+C (@code{LINK})
+@end enumerate
+
+For example, if Fortran 77, C and C++ source code is compiled
+into a program, then the C++ linker will be used. In this case, if the
+C or Fortran 77 linkers required any special libraries that weren't
+included by the C++ linker, then they must be manually added to an
+@code{_LDADD} or @code{_LIBADD} variable by the user writing the
+@file{Makefile.am}.
+
+Automake only looks at the file names listed in @file{_SOURCES}
+variables to choose the linker, and defaults to the C linker.
+Sometimes this is inconvenient because you are linking against a
+library written in another language and would like to set the linker
+more appropriately. @xref{Libtool Convenience Libraries}, for a
+trick with @code{nodist_EXTRA_@dots{}_SOURCES}.
+
+A per-target @code{_LINK} variable will override the above selection.
+Per-target link flags will cause Automake to write a per-target
+@code{_LINK} variable according to the language chosen as above.

+@node Dependencies
+@section Automatic dependency tracking
+
+As a developer it is often painful to continually update the
+@file{Makefile.am} whenever the include-file dependencies change in a
+project. Automake supplies a way to automatically track dependency
+changes (@pxref{Dependency Tracking}).
+
+@cindex Dependency tracking
+@cindex Automatic dependency tracking
+
+Automake always uses complete dependencies for a compilation,
+including system headers. Automake's model is that dependency
+computation should be a side effect of the build. To this end,
+dependencies are computed by running all compilations through a
+special wrapper program called @command{depcomp}. @command{depcomp}
+understands how to coax many different C and C++ compilers into
+generating dependency information in the format it requires.
+@samp{automake -a} will install @command{depcomp} into your source
+tree for you. If @command{depcomp} can't figure out how to properly
+invoke your compiler, dependency tracking will simply be disabled for
+your build.
+
+@cindex @command{depcomp}
+
+Experience with earlier versions of Automake (@pxref{Dependency Tracking
+Evolution, , Dependency Tracking Evolution, automake-history, Brief History
+of Automake}) taught us that it is not reliable to generate dependencies
+only on the maintainer's system, as configurations vary too much. So
+instead Automake implements dependency tracking at build time.

+@node EXEEXT
+@section Support for executable extensions
+
+@cindex Executable extension
+@cindex Extension, executable
+@cindex Windows
+
+On some platforms, such as Windows, executables are expected to have an
+extension such as @file{.exe}. On these platforms, some compilers (GCC
+among them) will automatically generate @file{foo.exe} when asked to
+generate @file{foo}.
+
+Automake provides mostly-transparent support for this. Unfortunately
+@emph{mostly} doesn't yet mean @emph{fully}. Until the English
+dictionary is revised, you will have to assist Automake if your package
+must support those platforms.
+
+One thing you must be aware of is that, internally, Automake rewrites
+something like this:
+
+@example
+bin_PROGRAMS = liver
+@end example
+
+to this:
+
+@example
+bin_PROGRAMS = liver$(EXEEXT)
+@end example
+
+The targets Automake generates are likewise given the @samp{$(EXEEXT)}
+extension.
+
+The variables @code{TESTS} and @code{XFAIL_TESTS} (@pxref{Simple Tests})
+are also rewritten if they contain filenames that have been declared as
+programs in the same @file{Makefile}. (This is mostly useful when some
+programs from @code{check_PROGRAMS} are listed in @code{TESTS}.)
+
+However, Automake cannot apply this rewriting to @command{configure}
+substitutions. This means that if you are conditionally building a
+program using such a substitution, then your @file{configure.ac} must
+take care to add @samp{$(EXEEXT)} when constructing the output variable.
+
+Sometimes maintainers like to write an explicit link rule for their
+program. Without executable extension support, this is easy---you
+simply write a rule whose target is the name of the program. However,
+when executable extension support is enabled, you must instead add the
+@samp{$(EXEEXT)} suffix.
+
+This might be a nuisance for maintainers who know their package will
+never run on a platform that has
+executable extensions. For those maintainers, the @option{no-exeext}
+option (@pxref{Options}) will disable this feature. This works in a
+fairly ugly way; if @option{no-exeext} is seen, then the presence of a
+rule for a target named @code{foo} in @file{Makefile.am} will override
+an @command{automake}-generated rule for @samp{foo$(EXEEXT)}. Without
+the @option{no-exeext} option, this use will give a diagnostic.

+@vindex _SCRIPTS
+@cindex Installing scripts
+
+It is possible to define and install programs that are scripts. Such
+programs are listed using the @code{SCRIPTS} primary name. When the
+script is distributed in its final, installable form, the
+@file{Makefile} usually looks as follows:
+@vindex SCRIPTS
+
+@example
+# Install my_script in $(bindir) and distribute it.
+dist_bin_SCRIPTS = my_script
+@end example
+
+Scripts are not distributed by default; as we have just seen, those
+that should be distributed can be specified using a @code{dist_}
+prefix as with other primaries.
+

+@vindex libexec_SCRIPTS
+@vindex pkgdata_SCRIPTS
+@vindex pkglibexec_SCRIPTS
+@vindex noinst_SCRIPTS
+@vindex check_SCRIPTS
+
+Scripts can be installed in @code{bindir}, @code{sbindir},
+@code{libexecdir}, @code{pkglibexecdir}, or @code{pkgdatadir}.
+
+Scripts that need not be installed can be listed in
+@code{noinst_SCRIPTS}, and among them, those which are needed only by
+@samp{make check} should go in @code{check_SCRIPTS}.
+
+When a script needs to be built, the @file{Makefile.am} should include
+the appropriate rules. For instance the @command{automake} program
+itself is a Perl script that is generated from @file{automake.in}.
+Here is how this is handled:
+
+@example
+bin_SCRIPTS = automake
+CLEANFILES = $(bin_SCRIPTS)
+EXTRA_DIST = automake.in
+
+do_subst = sed -e 's,[@@]datadir[@@],$(datadir),g' \
+ -e 's,[@@]PERL[@@],$(PERL),g' \
+ -e 's,[@@]PACKAGE[@@],$(PACKAGE),g' \
+ -e 's,[@@]VERSION[@@],$(VERSION),g' \
+ @dots{}
+
+automake: automake.in Makefile
+ $(do_subst) < $(srcdir)/automake.in > automake
+ chmod +x automake
+@end example
+
+Such scripts for which a build rule has been supplied need to be
+deleted explicitly using @code{CLEANFILES} (@pxref{Clean}), and their
+sources have to be distributed, usually with @code{EXTRA_DIST}
+(@pxref{Basics of Distribution}).
+
+Another common way to build scripts is to process them from
+@file{configure} with @code{AC_CONFIG_FILES}. In this situation
+Automake knows which files should be cleaned and distributed, and what
+the rebuild rules should look like.
+
+For instance if @file{configure.ac} contains
+
+@example
+AC_CONFIG_FILES([src/my_script], [chmod +x src/my_script])
+@end example
+
+@noindent
+to build @file{src/my_script} from @file{src/my_script.in}, then a
+@file{src/Makefile.am} to install this script in @code{$(bindir)} can
+be as simple as
+
+@example
+bin_SCRIPTS = my_script
+CLEANFILES = $(bin_SCRIPTS)
+@end example
+
+@noindent
+There is no need for @code{EXTRA_DIST} or any build rule: Automake
+infers them from @code{AC_CONFIG_FILES} (@pxref{Requirements}).
+@code{CLEANFILES} is still useful, because by default Automake will
+clean targets of @code{AC_CONFIG_FILES} in @code{distclean}, not
+@code{clean}.
+
+Although this looks simpler, building scripts this way has one
+drawback: directory variables such as @code{$(datadir)} are not fully
+expanded and may refer to other directory variables.

+@code{includedir}, @code{oldincludedir}, @code{pkgincludedir} or any
+other directory you may have defined (@pxref{Uniform}). For instance,
+
+@example
+include_HEADERS = foo.h bar/bar.h
+@end example
+
+@noindent
+will install the two files as @file{$(includedir)/foo.h} and
+@file{$(includedir)/bar.h}.
+
+The @code{nobase_} prefix is also supported,
+
+@example
+nobase_include_HEADERS = foo.h bar/bar.h
+@end example
+
+@noindent
+will install the two files as @file{$(includedir)/foo.h} and
+@file{$(includedir)/bar/bar.h} (@pxref{Alternative}).
+
+@vindex noinst_HEADERS
+Usually, only header files that accompany installed libraries need to
+be installed. Headers used by programs or convenience libraries are
+not installed. The @code{noinst_HEADERS} variable can be used for
+such headers. However when the header actually belongs to a single
+convenience library or program, we recommend listing it in the
+program's or library's @code{_SOURCES} variable (@pxref{Program
+Sources}) instead of in @code{noinst_HEADERS}. This is clearer for
+the @file{Makefile.am} reader. @code{noinst_HEADERS} would be the
+right variable to use in a directory containing only headers and no
+associated library or program.
+
+All header files must be listed somewhere; in a @code{_SOURCES}
+variable or in a @code{_HEADERS} variable. Missing ones will not
+appear in the distribution.
+
+For header files that are built and must not be distributed, use the
+@code{nodist_} prefix as in @code{nodist_include_HEADERS} or
+@code{nodist_prog_SOURCES}. If these generated headers are needed
+during the build, you must also ensure they exist before they are

+
+By default, data files are @emph{not} included in a distribution. Of

+@node Sources
+@section Built Sources
+
+Because Automake's automatic dependency tracking works as a side-effect
+of compilation (@pxref{Dependencies}) there is a bootstrap issue: a
+target should not be compiled before its dependencies are made, but
+these dependencies are unknown until the target is first compiled.
+
+Ordinarily this is not a problem, because dependencies are distributed
+sources: they preexist and do not need to be built. Suppose that
+@file{foo.c} includes @file{foo.h}. When it first compiles
+@file{foo.o}, @command{make} only knows that @file{foo.o} depends on
+@file{foo.c}. As a side-effect of this compilation @command{depcomp}
+records the @file{foo.h} dependency so that following invocations of
+@command{make} will honor it. In these conditions, it's clear there is
+no problem: either @file{foo.o} doesn't exist and has to be built
+(regardless of the dependencies), or accurate dependencies exist and
+they can be used to decide whether @file{foo.o} should be rebuilt.
+
+It's a different story if @file{foo.h} doesn't exist by the first
+@command{make} run. For instance, there might be a rule to build
+@file{foo.h}. This time @file{file.o}'s build will fail because the
+compiler can't find @file{foo.h}. @command{make} failed to trigger the
+rule to build @file{foo.h} first by lack of dependency information.
+
+@vindex BUILT_SOURCES
+@cindex @code{BUILT_SOURCES}, defined
+
+The @code{BUILT_SOURCES} variable is a workaround for this problem. A
+source file listed in @code{BUILT_SOURCES} is made on @samp{make all}
+or @samp{make check} (or even @samp{make install}) before other
+targets are processed. However, such a source file is not
+@emph{compiled} unless explicitly requested by mentioning it in some
+other @code{_SOURCES} variable.
+
+So, to conclude our introductory example, we could use
+@samp{BUILT_SOURCES = foo.h} to ensure @file{foo.h} gets built before
+any other target (including @file{foo.o}) during @samp{make all} or
+@samp{make check}.
+
+@code{BUILT_SOURCES} is actually a bit of a misnomer, as any file which
+must be created early in the build process can be listed in this
+variable. Moreover, all built sources do not necessarily have to be
+listed in @code{BUILT_SOURCES}. For instance, a generated @file{.c} file
+doesn't need to appear in @code{BUILT_SOURCES} (unless it is included by
+another source), because it's a known dependency of the associated
+object.
+
+It might be important to emphasize that @code{BUILT_SOURCES} is
+honored only by @samp{make all}, @samp{make check} and @samp{make
+install}. This means you cannot build a specific target (e.g.,
+@samp{make foo}) in a clean tree if it depends on a built source.
+However it will succeed if you have run @samp{make all} earlier,
+because accurate dependencies are already available.
+
+The next section illustrates and discusses the handling of built sources
+on a toy example.
+
+@menu
+* Built Sources Example:: Several ways to handle built sources.
+@end menu
+
+@node Built Sources Example
+@subsection Built Sources Example
+
+Suppose that @file{foo.c} includes @file{bindir.h}, which is
+installation-dependent and not distributed: it needs to be built. Here
+@file{bindir.h} defines the preprocessor macro @code{bindir} to the
+value of the @command{make} variable @code{bindir} (inherited from
+@file{configure}).
+
+We suggest several implementations below. It's not meant to be an
+exhaustive listing of all ways to handle built sources, but it will give
+you a few ideas if you encounter this issue.
+
+@subsubheading First Try
+
+This first implementation will illustrate the bootstrap issue mentioned
+in the previous section (@pxref{Sources}).
+
+Here is a tentative @file{Makefile.am}.
+
+@example
+# This won't work.
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c
+nodist_foo_SOURCES = bindir.h
+CLEANFILES = bindir.h
+bindir.h: Makefile
+ echo '#define bindir "$(bindir)"' >$@@
+@end example
+
+This setup doesn't work, because Automake doesn't know that @file{foo.c}
+includes @file{bindir.h}. Remember, automatic dependency tracking works
+as a side-effect of compilation, so the dependencies of @file{foo.o} will
+be known only after @file{foo.o} has been compiled (@pxref{Dependencies}).
+The symptom is as follows.
+
+@example
+% make
+source='foo.c' object='foo.o' libtool=no \
+depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+depmode=gcc /bin/sh ./depcomp \
+gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+foo.c:2: bindir.h: No such file or directory
+make: *** [foo.o] Error 1
+@end example
+
+In this example @file{bindir.h} is not distributed nor installed, and
+it is not even being built on-time. One may wonder if the
+@samp{nodist_foo_SOURCES = bindir.h} line has any use at all. This
+line simply states that @file{bindir.h} is a source of @code{foo}, so
+for instance, it should be inspected while generating tags
+(@pxref{Tags}). In other words, it does not help our present problem,
+and the build would fail identically without it.
+
+@subsubheading Using @code{BUILT_SOURCES}
+
+A solution is to require @file{bindir.h} to be built before anything
+else. This is what @code{BUILT_SOURCES} is meant for (@pxref{Sources}).
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c
+nodist_foo_SOURCES = bindir.h
+BUILT_SOURCES = bindir.h
+CLEANFILES = bindir.h
+bindir.h: Makefile
+ echo '#define bindir "$(bindir)"' >$@@
+@end example
+
+See how @file{bindir.h} gets built first:
+
+@example
+% make
+echo '#define bindir "/usr/local/bin"' >bindir.h
+make all-am
+make[1]: Entering directory `/home/adl/tmp'
+source='foo.c' object='foo.o' libtool=no \
+depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+depmode=gcc /bin/sh ./depcomp \
+gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+gcc -g -O2 -o foo foo.o
+make[1]: Leaving directory `/home/adl/tmp'
+@end example
+
+However, as said earlier, @code{BUILT_SOURCES} applies only to the
+@code{all}, @code{check}, and @code{install} targets. It still fails
+if you try to run @samp{make foo} explicitly:
+
+@example
+% make clean
+test -z "bindir.h" || rm -f bindir.h
+test -z "foo" || rm -f foo
+rm -f *.o
+% : > .deps/foo.Po # Suppress previously recorded dependencies
+% make foo
+source='foo.c' object='foo.o' libtool=no \
+depfile='.deps/foo.Po' tmpdepfile='.deps/foo.TPo' \
+depmode=gcc /bin/sh ./depcomp \
+gcc -I. -I. -g -O2 -c `test -f 'foo.c' || echo './'`foo.c
+foo.c:2: bindir.h: No such file or directory
+make: *** [foo.o] Error 1
+@end example
+
+@subsubheading Recording Dependencies manually
+
+Usually people are happy enough with @code{BUILT_SOURCES} because they
+never build targets such as @samp{make foo} before @samp{make all}, as
+in the previous example. However if this matters to you, you can
+avoid @code{BUILT_SOURCES} and record such dependencies explicitly in
+the @file{Makefile.am}.
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c
+nodist_foo_SOURCES = bindir.h
+foo.$(OBJEXT): bindir.h
+CLEANFILES = bindir.h
+bindir.h: Makefile
+ echo '#define bindir "$(bindir)"' >$@@
+@end example
+
+You don't have to list @emph{all} the dependencies of @file{foo.o}
+explicitly, only those that might need to be built. If a dependency
+already exists, it will not hinder the first compilation and will be
+recorded by the normal dependency tracking code. (Note that after
+this first compilation the dependency tracking code will also have
+recorded the dependency between @file{foo.o} and
+@file{bindir.h}; so our explicit dependency is really useful to
+the first build only.)
+
+Adding explicit dependencies like this can be a bit dangerous if you are
+not careful enough. This is due to the way Automake tries not to
+overwrite your rules (it assumes you know better than it).
+@samp{foo.$(OBJEXT): bindir.h} supersedes any rule Automake may want to
+output to build @samp{foo.$(OBJEXT)}. It happens to work in this case
+because Automake doesn't have to output any @samp{foo.$(OBJEXT):}
+target: it relies on a suffix rule instead (i.e., @samp{.c.$(OBJEXT):}).
+Always check the generated @file{Makefile.in} if you do this.
+
+@subsubheading Build @file{bindir.h} from @file{configure}
+
+It's possible to define this preprocessor macro from @file{configure},
+either in @file{config.h} (@pxref{Defining Directories, , Defining
+Directories, autoconf, The Autoconf Manual}), or by processing a
+@file{bindir.h.in} file using @code{AC_CONFIG_FILES}
+(@pxref{Configuration Actions, ,Configuration Actions, autoconf, The
+Autoconf Manual}).
+
+At this point it should be clear that building @file{bindir.h} from
+@file{configure} works well for this example. @file{bindir.h} will exist
+before you build any target, hence will not cause any dependency issue.
+
+The Makefile can be shrunk as follows. We do not even have to mention
+@file{bindir.h}.
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c
+@end example
+
+However, it's not always possible to build sources from
+@file{configure}, especially when these sources are generated by a tool
+that needs to be built first.
+
+@subsubheading Build @file{bindir.c}, not @file{bindir.h}.
+
+Another attractive idea is to define @code{bindir} as a variable or
+function exported from @file{bindir.o}, and build @file{bindir.c}
+instead of @file{bindir.h}.
+
+@example
+noinst_PROGRAMS = foo
+foo_SOURCES = foo.c bindir.h
+nodist_foo_SOURCES = bindir.c
+CLEANFILES = bindir.c
+bindir.c: Makefile
+ echo 'const char bindir[] = "$(bindir)";' >$@@
+@end example
+
+@file{bindir.h} contains just the variable's declaration and doesn't
+need to be built, so it won't cause any trouble. @file{bindir.o} is
+always dependent on @file{bindir.c}, so @file{bindir.c} will get built
+first.
+
+@subsubheading Which is best?
+
+There is no panacea, of course. Each solution has its merits and
+drawbacks.
+
+You cannot use @code{BUILT_SOURCES} if the ability to run @samp{make
+foo} on a clean tree is important to you.
+
+You won't add explicit dependencies if you are leery of overriding
+an Automake rule by mistake.
+
+Building files from @file{./configure} is not always possible, neither
+is converting @file{.h} files into @file{.c} files.

+
+Automake provides some support for Emacs Lisp. The @code{LISP} primary
+is used to hold a list of @file{.el} files. Possible prefixes for this
+primary are @code{lisp_} and @code{noinst_}. Note that if

+@code{AM_PATH_LISPDIR} (@pxref{Macros}).
+
+@vindex dist_lisp_LISP
+@vindex dist_noinst_LISP
+Lisp sources are not distributed by default. You can prefix the
+@code{LISP} primary with @code{dist_}, as in @code{dist_lisp_LISP} or
+@code{dist_noinst_LISP}, to indicate that these files should be
+distributed.
+
+Automake will byte-compile all Emacs Lisp source files using the Emacs
+found by @code{AM_PATH_LISPDIR}, if any was found.
+
+Byte-compiled Emacs Lisp files are not portable among all versions of
+Emacs, so it makes sense to turn this off if you expect sites to have
+more than one version of Emacs installed. Furthermore, many packages
+don't actually benefit from byte-compilation. Still, we recommend
+that you byte-compile your Emacs Lisp sources. It is probably better
+for sites with strange setups to cope for themselves than to make the
+installation less nice for everybody else.
+
+There are two ways to avoid byte-compiling. Historically, we have
+recommended the following construct.
+
+@example
+lisp_LISP = file1.el file2.el
+ELCFILES =
+@end example
+
+@noindent
+@code{ELCFILES} is an internal Automake variable that normally lists
+all @file{.elc} files that must be byte-compiled. Automake defines
+@code{ELCFILES} automatically from @code{lisp_LISP}. Emptying this
+variable explicitly prevents byte-compilation.
+
+Since Automake 1.8, we now recommend using @code{lisp_DATA} instead:
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+lisp_DATA = file1.el file2.el
+@end example
+
+Note that these two constructs are not equivalent. @code{_LISP} will
+not install a file if Emacs is not installed, while @code{_DATA} will
+always install its files.

+@cindex Restrictions for @code{JAVA}
+
+Currently Automake enforces the restriction that only one @code{_JAVA}
+primary can be used in a given @file{Makefile.am}. The reason for this
+restriction is that, in general, it isn't possible to know which
+@file{.class} files were generated from which @file{.java} files, so
+it would be impossible to know which files to install where. For
+instance, a @file{.java} file can define multiple classes; the resulting
+@file{.class} file names cannot be predicted without parsing the
+@file{.java} file.
+
+There are a few variables that are used when compiling Java sources:
+
+@vtable @code
+@item JAVAC
+The name of the Java compiler. This defaults to @samp{javac}.
+
+@item JAVACFLAGS
+The flags to pass to the compiler. This is considered to be a user
+variable (@pxref{User Variables}).
+
+@item AM_JAVACFLAGS
+More flags to pass to the Java compiler. This, and not
+@code{JAVACFLAGS}, should be used when it is necessary to put Java
+compiler flags into @file{Makefile.am}.
+
+@item JAVAROOT
+The value of this variable is passed to the @option{-d} option to
+@code{javac}. It defaults to @samp{$(top_builddir)}.
+
+@item CLASSPATH_ENV
+This variable is a shell expression that is used to set the
+@env{CLASSPATH} environment variable on the @code{javac} command line.
+(In the future we will probably handle class path setting differently.)

+@cindex @code{PYTHON} primary, defined
+@cindex Primary variable, @code{PYTHON}
+@vindex _PYTHON
+
+Automake provides support for Python compilation with the
+@code{PYTHON} primary. A typical setup is to call
+@code{AM_PATH_PYTHON} in @file{configure.ac} and use a line like the
+following in @file{Makefile.am}:
+
+@example
+python_PYTHON = tree.py leave.py
+@end example
+
+Any files listed in a @code{_PYTHON} variable will be byte-compiled
+with @command{py-compile} at install time. @command{py-compile}
+actually creates both standard (@file{.pyc}) and optimized
+(@file{.pyo}) byte-compiled versions of the source files. Note that
+because byte-compilation occurs at install time, any files listed in
+@code{noinst_PYTHON} will not be compiled. Python source files are
+included in the distribution by default, prepend @code{nodist_} (as in
+@code{nodist_python_PYTHON}) to omit them.
+
+Automake ships with an Autoconf macro called @code{AM_PATH_PYTHON}
+that will determine some Python-related directory variables (see
+below). If you have called @code{AM_PATH_PYTHON} from
+@file{configure.ac}, then you may use the variables
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@code{python_PYTHON} or @code{pkgpython_PYTHON} to list Python source
+files in your @file{Makefile.am}, depending on where you want your files
+installed (see the definitions of @code{pythondir} and
+@code{pkgpythondir} below).
+
+@defmac AM_PATH_PYTHON (@ovar{version}, @ovar{action-if-found},
+ @ovar{action-if-not-found})
+
+Search for a Python interpreter on the system. This macro takes three
+optional arguments. The first argument, if present, is the minimum
+version of Python required for this package: @code{AM_PATH_PYTHON}
+will skip any Python interpreter that is older than @var{version}.
+If an interpreter is found and satisfies @var{version}, then
+@var{action-if-found} is run. Otherwise, @var{action-if-not-found} is
+run.
+
+If @var{action-if-not-found} is not specified, as in the following
+example, the default is to abort @command{configure}.
+
+@example
+AM_PATH_PYTHON([2.2])
+@end example
+
+@noindent
+This is fine when Python is an absolute requirement for the package.
+If Python >= 2.5 was only @emph{optional} to the package,
+@code{AM_PATH_PYTHON} could be called as follows.
+
+@example
+AM_PATH_PYTHON([2.5],, [:])
+@end example
+
+If the @env{PYTHON} variable is set when @code{AM_PATH_PYTHON} is
+called, then that will be the only Python interpreter that is tried.
+
+@code{AM_PATH_PYTHON} creates the following output variables based on
+the Python installation found during configuration.
+@end defmac
+
+@vtable @code
+@item PYTHON
+The name of the Python executable, or @samp{:} if no suitable
+interpreter could be found.
+
+Assuming @var{action-if-not-found} is used (otherwise @file{./configure}
+will abort if Python is absent), the value of @code{PYTHON} can be used
+to setup a conditional in order to disable the relevant part of a build
+as follows.
+
+@example
+AM_PATH_PYTHON(,, [:])
+AM_CONDITIONAL([HAVE_PYTHON], [test "$PYTHON" != :])
+@end example
+
+@item PYTHON_VERSION
+The Python version number, in the form @var{major}.@var{minor}
+(e.g., @samp{2.5}). This is currently the value of
+@samp{sys.version[:3]}.
+
+@item PYTHON_PREFIX
+The string @samp{$@{prefix@}}. This term may be used in future work
+that needs the contents of Python's @samp{sys.prefix}, but general
+consensus is to always use the value from @command{configure}.
+
+@item PYTHON_EXEC_PREFIX
+The string @samp{$@{exec_prefix@}}. This term may be used in future work
+that needs the contents of Python's @samp{sys.exec_prefix}, but general
+consensus is to always use the value from @command{configure}.
+
+@item PYTHON_PLATFORM
+The canonical name used by Python to describe the operating system, as
+given by @samp{sys.platform}. This value is sometimes needed when
+building Python extensions.
+
+@item pythondir
+The directory name for the @file{site-packages} subdirectory of the
+standard Python install tree.
+
+@item pkgpythondir
+This is the directory under @code{pythondir} that is named after the
+package. That is, it is @samp{$(pythondir)/$(PACKAGE)}. It is provided
+as a convenience.
+
+@item pyexecdir
+This is the directory where Python extension modules (shared libraries)
+should be installed. An extension module written in C could be declared
+as follows to Automake:
+
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@example
+pyexec_LTLIBRARIES = quaternion.la
+quaternion_la_SOURCES = quaternion.c support.c support.h
+quaternion_la_LDFLAGS = -avoid-version -module
+@end example
+
+@item pkgpyexecdir
+This is a convenience variable that is defined as
+@samp{$(pyexecdir)/$(PACKAGE)}.
+@end vtable
+
+All these directory variables have values that start with either
+@samp{$@{prefix@}} or @samp{$@{exec_prefix@}} unexpanded. This works
+fine in @file{Makefiles}, but it makes these variables hard to use in
+@file{configure}. This is mandated by the GNU coding standards, so
+that the user can run @samp{make prefix=/foo install}. The Autoconf
+manual has a section with more details on this topic
+(@pxref{Installation Directory Variables, , Installation Directory
+Variables, autoconf, The Autoconf Manual}). See also @ref{Hard-Coded

+@vindex info_TEXINFOS
+
+If the current directory contains Texinfo source, you must declare it
+with the @code{TEXINFOS} primary. Generally Texinfo files are converted
+into info, and thus the @code{info_TEXINFOS} variable is most commonly used
+here. Any Texinfo source file must end in the @file{.texi},
+@file{.txi}, or @file{.texinfo} extension. We recommend @file{.texi}
+for new manuals.
+
+Automake generates rules to build @file{.info}, @file{.dvi},
+@file{.ps}, @file{.pdf} and @file{.html} files from your Texinfo
+sources. Following the GNU Coding Standards, only the @file{.info}
+files are built by @samp{make all} and installed by @samp{make
+install} (unless you use @option{no-installinfo}, see below).
+Furthermore, @file{.info} files are automatically distributed so that
+Texinfo is not a prerequisite for installing your package.

+can be installed with @samp{make install-dvi}, @samp{make install-ps},
+@samp{make install-pdf} and @samp{make install-html} explicitly.
+@samp{make uninstall} will remove everything: the Texinfo
+documentation installed by default as well as all the above optional
+formats.
+

+
+If the @file{.texi} file @code{@@include}s @file{version.texi}, then
+that file will be automatically generated. The file @file{version.texi}
+defines four Texinfo flag you can reference using
+@code{@@value@{EDITION@}}, @code{@@value@{VERSION@}},
+@code{@@value@{UPDATED@}}, and @code{@@value@{UPDATED-MONTH@}}.
+
+@table @code
+@item EDITION
+@itemx VERSION
+Both of these flags hold the version number of your program. They are
+kept separate for clarity.
+
+@item UPDATED
+This holds the date the primary @file{.texi} file was last modified.
+
+@item UPDATED-MONTH
+This holds the name of the month in which the primary @file{.texi} file
+was last modified.
+@end table
+
+The @file{version.texi} support requires the @command{mdate-sh}
+script; this script is supplied with Automake and automatically
+included when @command{automake} is invoked with the
+@option{--add-missing} option.
+
+If you have multiple Texinfo files, and you want to use the
+@file{version.texi} feature, then you have to have a separate version
+file for each Texinfo file. Automake will treat any include in a
+Texinfo file that matches @file{vers*.texi} just as an automatically
+generated version file.
+
+Sometimes an info file actually depends on more than one @file{.texi}
+file. For instance, in GNU Hello, @file{hello.texi} includes the file
+@file{fdl.texi}. You can tell Automake about these dependencies using
+the @code{@var{texi}_TEXINFOS} variable. Here is how GNU Hello does it:
+@vindex TEXINFOS
+@vindex _TEXINFOS
+
+@example
+info_TEXINFOS = hello.texi
+hello_TEXINFOS = fdl.texi
+@end example
+
+@cindex @file{texinfo.tex}
+
+By default, Automake requires the file @file{texinfo.tex} to appear in
+the same directory as the @file{Makefile.am} file that lists the
+@file{.texi} files. If you used @code{AC_CONFIG_AUX_DIR} in
+@file{configure.ac} (@pxref{Input, , Finding `configure' Input,
+autoconf, The Autoconf Manual}), then @file{texinfo.tex} is looked for
+there. In both cases, @command{automake} then supplies @file{texinfo.tex} if
+@option{--add-missing} is given, and takes care of its distribution.
+However, if you set the @code{TEXINFO_TEX} variable (see below),
+it overrides the location of the file and turns off its installation
+into the source as well as its distribution.
+
+The option @option{no-texinfo.tex} can be used to eliminate the
+requirement for the file @file{texinfo.tex}. Use of the variable
+@code{TEXINFO_TEX} is preferable, however, because that allows the
+@code{dvi}, @code{ps}, and @code{pdf} targets to still work.

+
+Automake generates an @code{install-info} rule; some people apparently
+use this. By default, info pages are installed by @samp{make
+install}, so running @code{make install-info} is pointless. This can
+be prevented via the @code{no-installinfo} option. In this case,
+@file{.info} files are not installed by default, and user must
+request this explicitly using @samp{make install-info}.
+
+@vindex AM_UPDATE_INFO_DIR
+By default, @code{make install-info} and @code{make install-info}
+will try to run the @command{install-info} program (if available)
+to update (or create) the @file{@code{$@{infodir@}}/dir} index.
+If this is undesired, it can be prevented by exporting the
+@code{AM_UPDATE_INFO_DIR} variable to "@code{no}".
+
+The following variables are used by the Texinfo build rules.
+
+@vtable @code
+@item MAKEINFO
+The name of the program invoked to build @file{.info} files. This
+variable is defined by Automake. If the @command{makeinfo} program is
+found on the system then it will be used by default; otherwise
+@command{missing} will be used instead.
+
+@item MAKEINFOHTML
+The command invoked to build @file{.html} files. Automake
+defines this to @samp{$(MAKEINFO) --html}.
+
+@item MAKEINFOFLAGS
+User flags passed to each invocation of @samp{$(MAKEINFO)} and
+@samp{$(MAKEINFOHTML)}. This user variable (@pxref{User Variables}) is
+not expected to be defined in any @file{Makefile}; it can be used by
+users to pass extra flags to suit their needs.
+
+@item AM_MAKEINFOFLAGS
+@itemx AM_MAKEINFOHTMLFLAGS
+Maintainer flags passed to each @command{makeinfo} invocation. Unlike
+@code{MAKEINFOFLAGS}, these variables are meant to be defined by
+maintainers in @file{Makefile.am}. @samp{$(AM_MAKEINFOFLAGS)} is
+passed to @code{makeinfo} when building @file{.info} files; and
+@samp{$(AM_MAKEINFOHTMLFLAGS)} is used when building @file{.html}
+files.
+
+@c Keep in sync with txinfo21.sh
+For instance, the following setting can be used to obtain one single
+@file{.html} file per manual, without node separators.
+@example
+AM_MAKEINFOHTMLFLAGS = --no-headers --no-split
+@end example
+
+@code{AM_MAKEINFOHTMLFLAGS} defaults to @samp{$(AM_MAKEINFOFLAGS)}.
+This means that defining @code{AM_MAKEINFOFLAGS} without defining
+@code{AM_MAKEINFOHTMLFLAGS} will impact builds of both @file{.info}
+and @file{.html} files.
+
+@item TEXI2DVI
+The name of the command that converts a @file{.texi} file into a
+@file{.dvi} file. This defaults to @samp{texi2dvi}, a script that ships
+with the Texinfo package.
+
+@item TEXI2PDF
+The name of the command that translates a @file{.texi} file into a
+@file{.pdf} file. This defaults to @samp{$(TEXI2DVI) --pdf --batch}.
+
+@item DVIPS
+The name of the command that builds a @file{.ps} file out of a
+@file{.dvi} file. This defaults to @samp{dvips}.
+
+@item TEXINFO_TEX
+
+If your package has Texinfo files in many directories, you can use the
+variable @code{TEXINFO_TEX} to tell Automake where to find the canonical
+@file{texinfo.tex} for your package. The value of this variable should
+be the relative path from the current @file{Makefile.am} to
+@file{texinfo.tex}:

+@vindex man_MANS
+A package can also include man pages (but see the GNU standards on this
+matter, @ref{Man Pages, , , standards, The GNU Coding Standards}.) Man
+pages are declared using the @code{MANS} primary. Generally the
+@code{man_MANS} variable is used. Man pages are automatically installed in
+the correct subdirectory of @code{mandir}, based on the file extension.
+
+File extensions such as @file{.1c} are handled by looking for the valid
+part of the extension and using that to determine the correct
+subdirectory of @code{mandir}. Valid section names are the digits
+@samp{0} through @samp{9}, and the letters @samp{l} and @samp{n}.
+
+Sometimes developers prefer to name a man page something like
+@file{foo.man} in the source, and then rename it to have the correct
+suffix, for example @file{foo.1}, when installing the file. Automake
+also supports this mode. For a valid section named @var{section},
+there is a corresponding directory named @samp{man@var{section}dir},
+and a corresponding @code{_MANS} variable. Files listed in such a
+variable are installed in the indicated section. If the file already
+has a valid suffix, then it is installed as-is; otherwise the file
+suffix is changed to match the section.
+
+For instance, consider this example:
+@example
+man1_MANS = rename.man thesame.1 alsothesame.1c
+@end example
+
+@noindent
+In this case, @file{rename.man} will be renamed to @file{rename.1} when

+
+By default, man pages are installed by @samp{make install}. However,
+since the GNU project does not require man pages, many maintainers do
+not expend effort to keep the man pages up to date. In these cases, the
+@option{no-installman} option will prevent the man pages from being
+installed by default. The user can still explicitly install them via
+@samp{make install-man}.
+
+For fast installation, with many files it is preferable to use
+@samp{man@var{section}_MANS} over @samp{man_MANS} as well as files that
+do not need to be renamed.
+
+Man pages are not currently considered to be source, because it is not
+uncommon for man pages to be automatically generated. Therefore they
+are not automatically included in the distribution. However, this can
+be changed by use of the @code{dist_} prefix. For instance here is
+how to distribute and install the two man pages of GNU @command{cpio}
+(which includes both Texinfo documentation and man pages):
+
+@example

+@node Basics of Installation
+@section Basics of Installation
+
+A file named in a primary is installed by copying the built file into
+the appropriate directory. The base name of the file is used when
+installing.
+
+@example
+bin_PROGRAMS = hello subdir/goodbye
+@end example
+
+In this example, both @samp{hello} and @samp{goodbye} will be installed
+in @samp{$(bindir)}.
+
+Sometimes it is useful to avoid the basename step at install time. For
+instance, you might have a number of header files in subdirectories of
+the source tree that are laid out precisely how you want to install
+them. In this situation you can use the @code{nobase_} prefix to
+suppress the base name step. For example:
+
+@example
+nobase_include_HEADERS = stdio.h sys/types.h
+@end example
+
+@noindent
+will install @file{stdio.h} in @samp{$(includedir)} and @file{types.h}
+in @samp{$(includedir)/sys}.
+
+For most file types, Automake will install multiple files at once, while
+avoiding command line length issues (@pxref{Length Limitations}). Since
+some @command{install} programs will not install the same file twice in
+one invocation, you may need to ensure that file lists are unique within
+one variable such as @samp{nobase_include_HEADERS} above.
+
+You should not rely on the order in which files listed in one variable
+are installed. Likewise, to cater for parallel make, you should not
+rely on any particular file installation order even among different
+file types (library dependencies are an exception here).
+

+@section The Two Parts of Install
+
+Automake generates separate @code{install-data} and @code{install-exec}
+rules, in case the installer is installing on multiple machines that
+share directory structure---these targets allow the machine-independent
+parts to be installed only once. @code{install-exec} installs
+platform-dependent files, and @code{install-data} installs
+platform-independent files. The @code{install} target depends on both
+of these targets. While Automake tries to automatically segregate
+objects into the correct category, the @file{Makefile.am} author is, in
+the end, responsible for making sure this is done correctly.

+
+Variables using the standard directory prefixes @samp{bin},

+
+Any variable using a user-defined directory prefix with
+@samp{exec} in the name (e.g.,
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+@code{myexecbin_PROGRAMS}) is installed by @code{install-exec}. All
+other user-defined prefixes are installed by @code{install-data}.
+
+@node Extending Installation
+@section Extending Installation
+
+It is possible to extend this mechanism by defining an
+@code{install-exec-local} or @code{install-data-local} rule. If these
+rules exist, they will be run at @samp{make install} time. These
+rules can do almost anything; care is required.
+@trindex install-exec-local
+@trindex install-data-local
+
+Automake also supports two install hooks, @code{install-exec-hook} and
+@code{install-data-hook}. These hooks are run after all other install
+rules of the appropriate type, exec or data, have completed. So, for
+instance, it is possible to perform post-installation modifications
+using an install hook. @xref{Extending}, for some examples.
+@cindex Install hook
+
+@node Staged Installs
+@section Staged Installs
+
+@vindex DESTDIR
+Automake generates support for the @code{DESTDIR} variable in all
+install rules. @code{DESTDIR} is used during the @samp{make install}
+step to relocate install objects into a staging area. Each object and
+path is prefixed with the value of @code{DESTDIR} before being copied
+into the install area. Here is an example of typical DESTDIR usage:
+
+@example
+mkdir /tmp/staging &&
+make DESTDIR=/tmp/staging install
+@end example
+
+The @command{mkdir} command avoids a security problem if the attacker
+creates a symbolic link from @file{/tmp/staging} to a victim area;
+then @command{make} places install objects in a directory tree built under
+@file{/tmp/staging}. If @file{/gnu/bin/foo} and
+@file{/gnu/share/aclocal/foo.m4} are to be installed, the above command
+would install @file{/tmp/staging/gnu/bin/foo} and
+@file{/tmp/staging/gnu/share/aclocal/foo.m4}.
+
+This feature is commonly used to build install images and packages
+(@pxref{DESTDIR}).
+
+Support for @code{DESTDIR} is implemented by coding it directly into
+the install rules. If your @file{Makefile.am} uses a local install
+rule (e.g., @code{install-exec-local}) or an install hook, then you
+must write that code to respect @code{DESTDIR}.

+@node Clean
+@chapter What Gets Cleaned
+
+@cindex @samp{make clean} support
+
+The GNU Makefile Standards specify a number of different clean rules.
+@xref{Standard Targets, , Standard Targets for Users, standards,
+The GNU Coding Standards}.
+
+Generally the files that can be cleaned are determined automatically by
+Automake. Of course, Automake also recognizes some variables that can
+be defined to specify additional files to clean. These variables are
+@code{MOSTLYCLEANFILES}, @code{CLEANFILES}, @code{DISTCLEANFILES}, and
+@code{MAINTAINERCLEANFILES}.
+@vindex MOSTLYCLEANFILES
+@vindex CLEANFILES
+@vindex DISTCLEANFILES
+@vindex MAINTAINERCLEANFILES
+
+@trindex mostlyclean-local
+@trindex clean-local
+@trindex distclean-local
+@trindex maintainer-clean-local
+When cleaning involves more than deleting some hard-coded list of
+files, it is also possible to supplement the cleaning rules with your
+own commands. Simply define a rule for any of the
+@code{mostlyclean-local}, @code{clean-local}, @code{distclean-local},
+or @code{maintainer-clean-local} targets (@pxref{Extending}). A common
+case is deleting a directory, for instance, a directory created by the
+test suite:
+
+@example
+clean-local:
+ -rm -rf testSubDir
+@end example
+
+Since @command{make} allows only one set of rules for a given target,
+a more extensible way of writing this is to use a separate target
+listed as a dependency:
+
+@example
+clean-local: clean-local-check
+.PHONY: clean-local-check
+clean-local-check:
+ -rm -rf testSubDir
+@end example
+
+As the GNU Standards aren't always explicit as to which files should
+be removed by which rule, we've adopted a heuristic that we believe
+was first formulated by Fran@,{c}ois Pinard:
+
+@itemize @bullet
+@item
+If @command{make} built it, and it is commonly something that one would
+want to rebuild (for instance, a @file{.o} file), then
+@code{mostlyclean} should delete it.
+
+@item
+Otherwise, if @command{make} built it, then @code{clean} should delete it.
+
+@item
+If @command{configure} built it, then @code{distclean} should delete it.
+
+@item
+If the maintainer built it (for instance, a @file{.info} file), then
+@code{maintainer-clean} should delete it. However
+@code{maintainer-clean} should not delete anything that needs to exist
+in order to run @samp{./configure && make}.
+@end itemize
+
+We recommend that you follow this same set of heuristics in your
+@file{Makefile.am}.

+@vindex VERSION
+@trindex dist
+The @code{dist} rule in the generated @file{Makefile.in} can be used
+to generate a gzipped @code{tar} file and other flavors of archive for
+distribution. The file is named based on the @code{PACKAGE} and
+@code{VERSION} variables defined by @code{AM_INIT_AUTOMAKE}
+(@pxref{Macros}); more precisely the gzipped @code{tar} file is named
+@samp{@var{package}-@var{version}.tar.gz}.
+@vindex GZIP_ENV
+You can use the @command{make} variable @code{GZIP_ENV} to control how gzip
+is run. The default setting is @option{--best}.
+
+@cindex @code{m4_include}, distribution
+@cindex @code{include}, distribution
+@acindex m4_include
+@cmindex include
+For the most part, the files to distribute are automatically found by
+Automake: all source files are automatically included in a distribution,
+as are all @file{Makefile.am} and @file{Makefile.in} files. Automake also
+has a built-in list of commonly used files that are automatically
+included if they are found in the current directory (either physically,
+or as the target of a @file{Makefile.am} rule); this list is printed by
+@samp{automake --help}. Note that some files in this list are actually
+distributed only if other certain conditions hold (for example,
+@c Keep in sync with autodist-config-headers.sh
+the @file{config.h.top} and @file{config.h.bot} files are automatically
+distributed only if, e.g., @samp{AC_CONFIG_HEADERS([config.h])} is used
+in @file{configure.ac}). Also, files that are read by @command{configure}
+(i.e.@: the source files corresponding to the files specified in various
+Autoconf macros such as @code{AC_CONFIG_FILES} and siblings) are
+automatically distributed. Files included in a @file{Makefile.am} (using
+@code{include}) or in @file{configure.ac} (using @code{m4_include}), and
+helper scripts installed with @samp{automake --add-missing} are also
+distributed.
+
+@vindex EXTRA_DIST
+Still, sometimes there are files that must be distributed, but which
+are not covered in the automatic rules. These files should be listed in
+the @code{EXTRA_DIST} variable. You can mention files from
+subdirectories in @code{EXTRA_DIST}.
+
+You can also mention a directory in @code{EXTRA_DIST}; in this case the
+entire directory will be recursively copied into the distribution.
+Please note that this will also copy @emph{everything} in the directory,
+including, e.g., Subversion's @file{.svn} private directories or CVS/RCS
+version control files. We recommend against using this feature.
+
+@vindex SUBDIRS
+@vindex DIST_SUBDIRS
+If you define @code{SUBDIRS}, Automake will recursively include the
+subdirectories in the distribution. If @code{SUBDIRS} is defined
+conditionally (@pxref{Conditionals}), Automake will normally include
+all directories that could possibly appear in @code{SUBDIRS} in the
+distribution. If you need to specify the set of directories
+conditionally, you can set the variable @code{DIST_SUBDIRS} to the
+exact list of subdirectories to include in the distribution
+(@pxref{Conditional Subdirectories}).
+
+
+@node Fine-grained Distribution Control
+@section Fine-grained Distribution Control
+
+@vindex dist_
+@vindex nodist_
+Sometimes you need tighter control over what does @emph{not} go into the
+distribution; for instance, you might have source files that are
+generated and that you do not want to distribute. In this case
+Automake gives fine-grained control using the @code{dist} and
+@code{nodist} prefixes. Any primary or @code{_SOURCES} variable can be
+prefixed with @code{dist_} to add the listed files to the distribution.
+Similarly, @code{nodist_} can be used to omit the files from the
+distribution.
+
+As an example, here is how you would cause some data to be distributed
+while leaving some source code out of the distribution:
+
+@example
+dist_data_DATA = distribute-this
+bin_PROGRAMS = foo
+nodist_foo_SOURCES = do-not-distribute.c
+@end example
+
+@node The dist Hook
+@section The dist Hook
+
+@trindex dist-hook
+
+Occasionally it is useful to be able to change the distribution before
+it is packaged up. If the @code{dist-hook} rule exists, it is run
+after the distribution directory is filled, but before the actual
+distribution archives are created. One way to use this is for
+removing unnecessary files that get recursively included by specifying
+a directory in @code{EXTRA_DIST}:
+
+@example
+EXTRA_DIST = doc
+dist-hook:
+ rm -rf `find $(distdir)/doc -type d -name .svn`
+@end example
+
+@c The caveates described here should be documented in 'disthook.test'.
+@noindent
+Note that the @code{dist-hook} recipe shouldn't assume that the regular
+files in the distribution directory are writable; this might not be the
+case if one is packaging from a read-only source tree, or when a
+@code{make distcheck} is being done. For similar reasons, the recipe
+shouldn't assume that the subdirectories put into the distribution
+directory as effect of having them listed in @code{EXTRA_DIST} are
+writable. So, if the @code{dist-hook} recipe wants to modify the
+content of an existing file (or @code{EXTRA_DIST} subdirectory) in the
+distribution directory, it should explicitly to make it writable first:
+
+@example
+EXTRA_DIST = README doc
+dist-hook:
+ chmod u+w $(distdir)/README $(distdir)/doc
+ echo "Distribution date: `date`" >> README
+ rm -f $(distdir)/doc/HACKING
+@end example
+
+@vindex distdir
+@vindex top_distdir
+Two variables that come handy when writing @code{dist-hook} rules are
+@samp{$(distdir)} and @samp{$(top_distdir)}.
+
+@samp{$(distdir)} points to the directory where the @code{dist} rule
+will copy files from the current directory before creating the
+tarball. If you are at the top-level directory, then @samp{distdir =
+$(PACKAGE)-$(VERSION)}. When used from subdirectory named
+@file{foo/}, then @samp{distdir = ../$(PACKAGE)-$(VERSION)/foo}.
+@samp{$(distdir)} can be a relative or absolute path, do not assume
+any form.
+
+@samp{$(top_distdir)} always points to the root directory of the
+distributed tree. At the top-level it's equal to @samp{$(distdir)}.
+In the @file{foo/} subdirectory
+@samp{top_distdir = ../$(PACKAGE)-$(VERSION)}.
+@samp{$(top_distdir)} too can be a relative or absolute path.
+
+Note that when packages are nested using @code{AC_CONFIG_SUBDIRS}
+(@pxref{Subpackages}), then @samp{$(distdir)} and
+@samp{$(top_distdir)} are relative to the package where @samp{make
+dist} was run, not to any sub-packages involved.
+
+@node Checking the Distribution
+@section Checking the Distribution
+
+@cindex @samp{make distcheck}
+@trindex distcheck
+Automake also generates a @code{distcheck} rule that can be of help
+to ensure that a given distribution will actually work. Simplifying
+a bit, we can say this rule first makes a distribution, and then,
+@emph{operating from it}, takes the following steps:
+@itemize
+@item
+tries to do a @code{VPATH} build (@pxref{VPATH Builds}), with the
+@code{srcdir} and all its content made @emph{read-only};
+@item
+runs the test suite (with @command{make check}) on this fresh build;
+@item
+installs the package in a temporary directory (with @command{make
+install}), and tries runs the test suite on the resulting installation
+(with @command{make installcheck});
+@item
+checks that the package can be correctly uninstalled (by @command{make
+uninstall}) and cleaned (by @code{make distclean});
+@item
+finally, makes another tarball to ensure the distribution is
+self-contained.
+@end itemize
+
+@vindex AM_DISTCHECK_CONFIGURE_FLAGS
+@vindex DISTCHECK_CONFIGURE_FLAGS
+@subheading DISTCHECK_CONFIGURE_FLAGS
+Building the package involves running @samp{./configure}. If you need
+to supply additional flags to @command{configure}, define them in the
+@code{AM_DISTCHECK_CONFIGURE_FLAGS} variable in your top-level
+@file{Makefile.am}. The user can still extend or override the flags
+provided there by defining the @code{DISTCHECK_CONFIGURE_FLAGS} variable,
+on the command line when invoking @command{make}.
+
+Still, developers are encouraged to strive to make their code buildable
+without requiring any special configure option; thus, in general, you
+shouldn't define @code{AM_DISTCHECK_CONFIGURE_FLAGS}. However, there
+might be few scenarios in which the use of this variable is justified.
+GNU @command{m4} offers an example. GNU @command{m4} configures by
+default with its experimental and seldom used "changeword" feature
+disabled; so in its case it is useful to have @command{make distcheck}
+run configure with the @option{--with-changeword} option, to ensure that
+the code for changeword support still compiles correctly.
+GNU @command{m4} also employs the @code{AM_DISTCHECK_CONFIGURE_FLAGS}
+variable to stress-test the use of @option{--program-prefix=g}, since at
+one point the @command{m4} build system had a bug where @command{make
+installcheck} was wrongly assuming it could blindly test "@command{m4}",
+rather than the just-installed "@command{gm4}".
+
+@trindex distcheck-hook
+@subheading distcheck-hook
+If the @code{distcheck-hook} rule is defined in your top-level
+@file{Makefile.am}, then it will be invoked by @code{distcheck} after
+the new distribution has been unpacked, but before the unpacked copy
+is configured and built. Your @code{distcheck-hook} can do almost
+anything, though as always caution is advised. Generally this hook is
+used to check for potential distribution errors not caught by the
+standard mechanism. Note that @code{distcheck-hook} as well as
+@code{AM_DISTCHECK_CONFIGURE_FLAGS} and @code{DISTCHECK_CONFIGURE_FLAGS}
+are not honored in a subpackage @file{Makefile.am}, but the flags from
+@code{AM_DISTCHECK_CONFIGURE_FLAGS} and @code{DISTCHECK_CONFIGURE_FLAGS}
+are passed down to the @command{configure} script of the subpackage.
+
+@cindex @samp{make distcleancheck}
+@trindex distcleancheck
+@vindex DISTCLEANFILES
+@vindex distcleancheck_listfiles
+
+@subheading distcleancheck
+Speaking of potential distribution errors, @code{distcheck} also
+ensures that the @code{distclean} rule actually removes all built
+files. This is done by running @samp{make distcleancheck} at the end of
+the @code{VPATH} build. By default, @code{distcleancheck} will run
+@code{distclean} and then make sure the build tree has been emptied by
+running @samp{$(distcleancheck_listfiles)}. Usually this check will
+find generated files that you forgot to add to the @code{DISTCLEANFILES}
+variable (@pxref{Clean}).
+
+The @code{distcleancheck} behavior should be OK for most packages,
+otherwise you have the possibility to override the definition of
+either the @code{distcleancheck} rule, or the
+@samp{$(distcleancheck_listfiles)} variable. For instance, to disable
+@code{distcleancheck} completely, add the following rule to your
+top-level @file{Makefile.am}:
+
+@example
+distcleancheck:
+ @@:
+@end example
+
+If you want @code{distcleancheck} to ignore built files that have not
+been cleaned because they are also part of the distribution, add the
+following definition instead:
+
+@c Keep in sync with distcleancheck.sh
+@example
+distcleancheck_listfiles = \
+ find . -type f -exec sh -c 'test -f $(srcdir)/$$1 || echo $$1' \
+ sh '@{@}' ';'
+@end example
+
+The above definition is not the default because it's usually an error if
+your Makefiles cause some distributed files to be rebuilt when the user
+build the package. (Think about the user missing the tool required to
+build the file; or if the required tool is built by your package,
+consider the cross-compilation case where it can't be run.) There is
+an entry in the FAQ about this (@pxref{Errors with distclean}), make
+sure you read it before playing with @code{distcleancheck_listfiles}.
+
+@cindex @samp{make distuninstallcheck}
+@trindex distuninstallcheck
+@vindex distuninstallcheck_listfiles
+
+@subheading distuninstallcheck
+@code{distcheck} also checks that the @code{uninstall} rule works
+properly, both for ordinary and @code{DESTDIR} builds. It does this
+by invoking @samp{make uninstall}, and then it checks the install tree
+to see if any files are left over. This check will make sure that you
+correctly coded your @code{uninstall}-related rules.
+
+By default, the checking is done by the @code{distuninstallcheck} rule,
+and the list of files in the install tree is generated by
+@samp{$(distuninstallcheck_listfiles)} (this is a variable whose value is
+a shell command to run that prints the list of files to stdout).
+
+Either of these can be overridden to modify the behavior of
+@code{distcheck}. For instance, to disable this check completely, you
+would write:
+
+@example
+distuninstallcheck:

+@section Generalities about Testing
+
+The purpose of testing is to determine whether a program or system behaves
+as expected (e.g., known inputs produce the expected outputs, error
+conditions are correctly handled or reported, and older bugs do not
+resurface).
+
+@cindex test case
+The minimal unit of testing is usually called @emph{test case}, or simply
+@emph{test}. How a test case is defined or delimited, and even what
+exactly @emph{constitutes} a test case, depends heavily on the testing
+paradigm and/or framework in use, so we won't attempt any more precise
+definition. The set of the test cases for a given program or system
+constitutes its @emph{testsuite}.
+
+@cindex test harness
+@cindex testsuite harness
+A @emph{test harness} (also @emph{testsuite harness}) is a program or
+software component that executes all (or part of) the defined test cases,
+analyzes their outcomes, and report or register these outcomes
+appropriately. Again, the details of how this is accomplished (and how
+the developer and user can influence it or interface with it) varies
+wildly, and we'll attempt no precise definition.
+
+@cindex test pass
+@cindex test failure
+A test is said to @emph{pass} when it can determine that the condition or
+behaviour it means to verify holds, and is said to @emph{fail} when it can
+determine that such condition of behaviour does @emph{not} hold.
+
+@cindex test skip
+Sometimes, tests can rely on non-portable tools or prerequisites, or
+simply make no sense on a given system (for example, a test checking a
+Windows-specific feature makes no sense on a GNU/Linux system). In this
+case, accordingly to the definition above, the tests can neither be
+considered passed nor failed; instead, they are @emph{skipped} -- i.e.,
+they are not run, or their result is anyway ignored for what concerns
+the count of failures an successes. Skips are usually explicitly
+reported though, so that the user will be aware that not all of the
+testsuite has really run.
+
+@cindex xfail
+@cindex expected failure
+@cindex expected test failure
+@cindex xpass
+@cindex unexpected pass
+@cindex unexpected test pass
+It's not uncommon, especially during early development stages, that some
+tests fail for known reasons, and that the developer doesn't want to
+tackle these failures immediately (this is especially true when the
+failing tests deal with corner cases). In this situation, the better
+policy is to declare that each of those failures is an @emph{expected
+failure} (or @emph{xfail}). In case a test that is expected to fail ends
+up passing instead, many testing environments will flag the result as a
+special kind of failure called @emph{unexpected pass} (or @emph{xpass}).
+
+@cindex hard error
+@cindex Distinction between errors and failures in testsuites
+Many testing environments and frameworks distinguish between test failures
+and hard errors. As we've seen, a test failure happens when some invariant
+or expected behaviour of the software under test is not met. An @emph{hard
+error} happens when e.g., the set-up of a test case scenario fails, or when
+some other unexpected or highly undesirable condition is encountered (for
+example, the program under test experiences a segmentation fault).

+
+@node Scripts-based Testsuites
+@subsection Scripts-based Testsuites
+
+If the special variable @code{TESTS} is defined, its value is taken to be
+a list of programs or scripts to run in order to do the testing. Under
+the appropriate circumstances, it's possible for @code{TESTS} to list
+also data files to be passed to one or more test scripts defined by
+different means (the so-called ``log compilers'', @pxref{Parallel Test
+Harness}).
+
+Test scripts can be executed serially or concurrently. Automake
+supports both these kinds of test execution, with the serial test harness
+being the default (for backward-compatibility reasons only, as its use
+is nowadays discouraged). The concurrent test harness relies on the
+concurrence capabilities (if any) offered by the underlying @command{make}
+implementation, and can thus only be as good as those are.
+
+By default, only the exit statuses of the test scripts are considered when
+determining the testsuite outcome. But Automake allows also the use of
+more complex test protocols, either standard (@pxref{Using the TAP test
+protocol}) or custom (@pxref{Custom Test Drivers}). Note that you can
+enable such protocols only when the parallel harness is used: they won't
+work with the serial test harness. In the rest of this section we are
+going to concentrate mostly on protocol-less tests, since we cover
+test protocols in a later section (again, @pxref{Custom Test Drivers}).
+
+@cindex Exit status 77, special interpretation
+@cindex Exit status 99, special interpretation
+When no test protocol is in use, an exit status of 0 from a test script will
+denote a success, an exit status of 77 a skipped test, an exit status of 99
+an hard error, and any other exit status will denote a failure.
+
+@cindex Tests, expected failure
+@cindex Expected test failure
+@vindex XFAIL_TESTS
+@vindex DISABLE_HARD_ERRORS
+@cindex Disabling hard errors
+You may define the variable @code{XFAIL_TESTS} to a list of tests
+(usually a subset of @code{TESTS}) that are expected to fail; this will
+effectively reverse the result of those tests (with the provision that
+skips and hard errors remain untouched). You may also instruct the
+testsuite harness to treat hard errors like simple failures, by defining
+the @code{DISABLE_HARD_ERRORS} make variable to a nonempty value.
+
+Note however that, for tests based on more complex test protocols,
+the exact effects of @code{XFAIL_TESTS} and @code{DISABLE_HARD_ERRORS}
+might change, or they might even have no effect at all (for example,
+@c Keep this in sync with tap-no-disable-hard-errors.sh
+in tests using TAP, there is not way to disable hard errors, and the
+@code{DISABLE_HARD_ERRORS} variable has no effect on them).
+
+@anchor{Testsuite progress on console}
+@cindex Testsuite progress on console
+The result of each test case run by the scripts in @code{TESTS} will be
+printed on standard output, along with the test name. For test protocols
+that allow more test cases per test script (such as TAP), a number,
+identifier and/or brief description specific for the single test case is
+expected to be printed in addition to the name of the test script. The
+possible results (whose meanings should be clear from the previous
+@ref{Generalities about Testing}) are @code{PASS}, @code{FAIL},
+@code{SKIP}, @code{XFAIL}, @code{XPASS} and @code{ERROR}. Here is an
+example of output from an hypothetical testsuite that uses both plain
+and TAP tests:
+@c Keep in sync with tap-doc.sh

+PASS: zardoz.tap 1 - Daemon started

+@samp{AM_COLOR_TESTS=no}, or force colored output even without a connecting
+terminal with @samp{AM_COLOR_TESTS=always}. It's also worth noting that
+some @command{make} implementations, when used in parallel mode, have
+slightly different semantics (@pxref{Parallel make,,, autoconf,
+The Autoconf Manual}), which can break the automatic detection of a
+connection to a capable terminal. If this is the case, you'll have to
+resort to the use of @samp{AM_COLOR_TESTS=always} in order to have the
+testsuite output colorized.
+
+Test programs that need data files should look for them in @code{srcdir}
+(which is both a make variable and an environment variable made available
+to the tests), so that they work when building in a separate directory
+(@pxref{Build Directories, , Build Directories , autoconf,
+The Autoconf Manual}), and in particular for the @code{distcheck} rule
+(@pxref{Checking the Distribution}).
+
+@vindex TESTS
+@vindex TESTS_ENVIRONMENT
+@vindex AM_TESTS_ENVIRONMENT
+The @code{AM_TESTS_ENVIRONMENT} and @code{TESTS_ENVIRONMENT} variables can
+be used to run initialization code and set environment variables for the
+test scripts. The former variable is developer-reserved, and can be
+defined in the @file{Makefile.am}, while the latter is reserved for the
+user, which can employ it to extend or override the settings in the
+former; for this to work portably, however, the contents of a non-empty
+@code{AM_TESTS_ENVIRONMENT} @emph{must} be terminated by a semicolon.
+
+@vindex AM_TESTS_FD_REDIRECT
+The @code{AM_TESTS_FD_REDIRECT} variable can be used to define file
+descriptor redirections for the test scripts. One might think that
+@code{AM_TESTS_ENVIRONMENT} could be used for this purpose, but experience
+has shown that doing so portably is practically impossible. The main
+hurdle is constituted by Korn shells, which usually set the close-on-exec
+flag on file descriptors opened with the @command{exec} builtin, thus
+rendering an idiom like @code{AM_TESTS_ENVIRONMENT = exec 9>&2;}
+ineffectual. This issue also affects some Bourne shells, such as the
+HP-UX's @command{/bin/sh},
+@c FIXME: should we offer a link to the relevant discussions on the
+@c bug-autoconf list?
+
+@c Keep in sync with tests-environment-backcompat.sh
+@example
+AM_TESTS_ENVIRONMENT = \
+## Some environment initializations are kept in a separate shell
+## file `tests-env.sh', which can make it easier to also run tests
+## from the command line.
+ . $(srcdir)/tests-env.sh; \
+## On Solaris, prefer more POSIX-compliant versions of the standard
+## tools by default.
+ if test -d /usr/xpg4/bin; then \
+ PATH=/usr/xpg4/bin:$$PATH; export PATH; \
+ fi;
+@c $$ restore font-lock
+## With this, the test scripts will be able to print diagnostic
+## messages to the original standard error stream, even if the test
+## driver redirects the stderr of the test scripts to a log file
+## before executing them.
+AM_TESTS_FD_REDIRECT = 9>&2
+@end example
+
+@noindent
+Note however that @code{AM_TESTS_ENVIRONMENT} is, for historical and
+implementation reasons, @emph{not} supported by the serial harness
+(@pxref{Serial Test Harness}).
+
+Automake ensures that each file listed in @code{TESTS} is built before
+it is run; you can list both source and derived programs (or scripts)
+in @code{TESTS}; the generated rule will look both in @code{srcdir} and
+@file{.}. For instance, you might want to run a C program as a test.
+To do this you would list its name in @code{TESTS} and also in
+@code{check_PROGRAMS}, and then specify it as you would any other
+program.
+
+Programs listed in @code{check_PROGRAMS} (and @code{check_LIBRARIES},
+@code{check_LTLIBRARIES}...) are only built during @code{make check},
+not during @code{make all}. You should list there any program needed
+by your tests that does not need to be built by @code{make all}. Note
+that @code{check_PROGRAMS} are @emph{not} automatically added to
+@code{TESTS} because @code{check_PROGRAMS} usually lists programs used
+by the tests, not the tests themselves. Of course you can set
+@code{TESTS = $(check_PROGRAMS)} if all your programs are test cases.
+
+@node Serial Test Harness
+@subsection Serial Test Harness
+@cindex @option{serial-tests}, Using
+
+@emph{NOTE:} This harness, while still being the default one, is
+obsolescent, and kept mostly for backward-compatibility reasons. The user
+is advised to use the parallel test harness instead (@pxref{Parallel Test
+Harness}). Be warned that future Automake versions might switch to use
+that more modern and feature-rich harness by default.
+
+The serial test harness is enabled by the Automake option
+@option{serial-tests}. It operates by simply running the tests serially,
+one at the time, without any I/O redirection. It's up to the user to
+implement logging of tests' output, if that's requited or desired.
+@c TODO: give an example of how this can be done.
+
+For historical and implementation reasons, the @code{AM_TESTS_ENVIRONMENT}
+variable is @emph{not} supported by this harness (it will be silently
+ignored if defined); only @code{TESTS_ENVIRONMENT} is, and it is to be
+considered a developer-reserved variable. This is done so that, when
+using the serial harness, @code{TESTS_ENVIRONMENT} can be defined to an
+invocation of an interpreter through which the tests are to be run.
+For instance, the following setup may be used to run tests with Perl:
+
+@example
+TESTS_ENVIRONMENT = $(PERL) -Mstrict -w
+TESTS = foo.pl bar.pl baz.pl
+@end example
+
+@noindent
+It's important to note that the use of @code{TESTS_ENVIRONMENT} endorsed
+here would be @emph{invalid} with the parallel harness. That harness
+provides a more elegant way to achieve the same effect, with the further
+benefit of freeing the @code{TESTS_ENVIRONMENT} variable for the user
+(@pxref{Parallel Test Harness}).
+
+Another, less serious limit of the serial harness is that it doesn't
+really distinguish between simple failures and hard errors; this is
+due to historical reasons only, and might be fixed in future Automake
+versions.
+
+@node Parallel Test Harness
+@subsection Parallel Test Harness
+@cindex @option{parallel-tests}, Using
+
+The parallel (or concurrent) test harness is enabled by the Automake option
+@option{parallel-tests}. It features automatic collection of the test
+scripts output in @file{.log} files, concurrent execution of tests with
+@code{make -j}, specification of inter-test dependencies, lazy reruns of
+tests that have not completed in a prior run, and hard errors for exceptional
+failures.
+
+This harness is still somewhat experimental and may undergo changes in
+order to satisfy additional portability requirements.
+
+@anchor{Basics of test metadata}
+@vindex TEST_SUITE_LOG
+@vindex TESTS
+@cindex @file{.log} files
+@cindex @file{.trs} files
+@cindex test metadata
+The parallel test harness operates by defining a set of @command{make}
+rules that run the test scripts listed in @code{TESTS}, and, for each
+such script, save its output in a corresponding @file{.log} file and
+its results (and other ``metadata'', @pxref{API for Custom Test Drivers})
+in a corresponding @file{.trs} (as in @b{T}est @b{R}e@b{S}ults) file.
+@c We choose the `.trs' extension also because, at the time of writing,
+@c it isn't already used for other significant purposes; see e.g.:
+@c - http://filext.com/file-extension/trs
+@c - http://www.file-extensions.org/search/?searchstring=trs
+The @file{.log} file will contain all the output emitted by the test on
+its standard output and its standard error. The @file{.trs} file will
+contain, among the other things, the results of the test cases run by
+the script.
+
+The parallel test harness will also create a summary log file,
+@code{TEST_SUITE_LOG}, which defaults to @file{test-suite.log} and requires
+a @file{.log} suffix. This file depends upon all the @file{.log} and
+@file{.trs} files created for the test scripts listed in @code{TESTS}.
+
+@vindex VERBOSE
+As with the serial harness above, by default one status line is printed
+per completed test, and a short summary after the suite has completed.
+However, standard output and standard error of the test are redirected
+to a per-test log file, so that parallel execution does not produce
+intermingled output. The output from failed tests is collected in the
+@file{test-suite.log} file. If the variable @samp{VERBOSE} is set, this
+file is output after the summary.
+@c FIXME: we should be clearer about what we mean exactly here ...
+For best results, the tests should be verbose by default now.
+
+@vindex TEST_EXTENSIONS
+@vindex TEST_LOGS
+Each couple of @file{.log} and @file{.trs} files is created when the
+corresponding test has completed. The set of log files is listed in
+the read-only variable @code{TEST_LOGS}, and defaults to @code{TESTS},
+with the executable extension if any (@pxref{EXEEXT}), as well as any
+suffix listed in @code{TEST_EXTENSIONS} removed, and @file{.log} appended.
+Results are undefined if a test file name ends in several concatenated
+suffixes. @code{TEST_EXTENSIONS} defaults to @file{.test}; it can be
+overridden by the user, in which case any extension listed in it must be
+constituted by a dot, followed by a non-digit alphabetic character,
+followed by any number of alphabetic characters.
+@c Keep in sync with test-extensions.sh
+For example, @samp{.sh}, @samp{.T} and @samp{.t1} are valid extensions,
+while @samp{.x-y}, @samp{.6c} and @samp{.t.1} are not.
+
+@vindex _LOG_COMPILE
+@vindex _LOG_COMPILER
+@vindex _LOG_FLAGS
+@vindex LOG_COMPILE
+@vindex LOG_COMPILER
+@vindex LOG_FLAGS
+@vindex @var{ext}_LOG_COMPILE
+@vindex @var{ext}_LOG_COMPILER
+@vindex @var{ext}_LOG_FLAGS
+@vindex AM_@var{ext}_LOG_FLAGS
+@vindex AM_LOG_FLAGS
+For tests that match an extension @code{.@var{ext}} listed in
+@code{TEST_EXTENSIONS}, you can provide a custom ``test runner'' using
+the variable @code{@var{ext}_LOG_COMPILER} (note the upper-case
+extension) and pass options in @code{AM_@var{ext}_LOG_FLAGS} and allow
+the user to pass options in @code{@var{ext}_LOG_FLAGS}. It will cause
+all tests with this extension to be called with this runner. For all
+tests without a registered extension, the variables @code{LOG_COMPILER},
+@code{AM_LOG_FLAGS}, and @code{LOG_FLAGS} may be used. For example,
+
+@c Keep in sync with parallel-tests-log-compiler-example.sh
+@example
+TESTS = foo.pl bar.py baz
+TEST_EXTENSIONS = .pl .py
+PL_LOG_COMPILER = $(PERL)
+AM_PL_LOG_FLAGS = -w
+PY_LOG_COMPILER = $(PYTHON)
+AM_PY_LOG_FLAGS = -v
+LOG_COMPILER = ./wrapper-script
+AM_LOG_FLAGS = -d
+@end example
+
+@noindent
+will invoke @samp{$(PERL) -w foo.pl}, @samp{$(PYTHON) -v bar.py},
+and @samp{./wrapper-script -d baz} to produce @file{foo.log},
+@file{bar.log}, and @file{baz.log}, respectively. The @file{foo.trs},
+@file{bar.trs} and @file{baz.trs} files will be automatically produced
+as a side-effect.
+
+It's important to note that, differently from what we've seen for the
+serial test harness (@pxref{Parallel Test Harness}), the
+@code{AM_TESTS_ENVIRONMENT} and @code{TESTS_ENVIRONMENT} variables
+@emph{cannot} be use to define a custom test runner; the
+@code{LOG_COMPILER} and @code{LOG_FLAGS} (or their extension-specific
+counterparts) should be used instead:
+
+@example
+## This is WRONG!
+AM_TESTS_ENVIRONMENT = PERL5LIB='$(srcdir)/lib' $(PERL) -Mstrict -w
+@end example
+
+@example
+## Do this instead.
+AM_TESTS_ENVIRONMENT = PERL5LIB='$(srcdir)/lib'; export PERL5LIB;
+LOG_COMPILER = $(PERL)
+AM_LOG_FLAGS = -Mstrict -w
+@end example
+
+By default, the test suite harness will run all tests, but there are
+several ways to limit the set of tests that are run:
+
+@itemize @bullet
+@item
+You can set the @code{TESTS} variable. For example, you can use a
+command like this to run only a subset of the tests:
+
+@example
+env TESTS="foo.test bar.test" make -e check
+@end example
+
+Note however that the command above will unconditionally overwrite the
+@file{test-suite.log} file, thus clobbering the recorded results
+of any previous testsuite run. This might be undesirable for packages
+whose testsuite takes long time to execute. Luckily, this problem can
+easily be avoided by overriding also @code{TEST_SUITE_LOG} at runtime;
+for example,
+
+@c Keep in sync with parallel-tests-log-override-2.sh
+@example
+env TEST_SUITE_LOG=partial.log TESTS="..." make -e check
+@end example
+
+will write the result of the partial testsuite runs to the
+@file{partial.log}, without touching @file{test-suite.log}.
+
+@item
+You can set the @code{TEST_LOGS} variable. By default, this variable is
+computed at @command{make} run time from the value of @code{TESTS} as
+described above. For example, you can use the following:
+
+@example
+set x subset*.log; shift
+env TEST_LOGS="foo.log $*" make -e check
+@end example
+
+The comments made above about @code{TEST_SUITE_LOG} overriding applies
+here too.
+
+@item
+@vindex RECHECK_LOGS
+@cindex lazy test execution
+By default, the test harness removes all old per-test @file{.log} and
+@file{.trs} files before it starts running tests to regenerate them. The
+variable @code{RECHECK_LOGS} contains the set of @file{.log} (and, by
+implication, @file{.trs}) files which are removed. @code{RECHECK_LOGS}
+defaults to @code{TEST_LOGS}, which means all tests need to be rechecked.
+By overriding this variable, you can choose which tests need to be
+reconsidered. For example, you can lazily rerun only those tests which
+are outdated, i.e., older than their prerequisite test files, by setting
+this variable to the empty value:
+
+@example
+env RECHECK_LOGS= make -e check
+@end example
+
+@item
+@trindex recheck
+You can ensure that all tests are rerun which have failed or passed
+unexpectedly, by running @code{make recheck} in the test directory.
+This convenience target will set @code{RECHECK_LOGS} appropriately
+before invoking the main test harness.
+@end itemize
+
+@noindent
+In order to guarantee an ordering between tests even with @code{make
+-j@var{N}}, dependencies between the corresponding @file{.log} files
+may be specified through usual @command{make} dependencies. For example,
+the following snippet lets the test named @file{foo-execute.test} depend
+upon completion of the test @file{foo-compile.test}:
+
+@example
+TESTS = foo-compile.test foo-execute.test
+foo-execute.log: foo-compile.log
+@end example
+
+@noindent
+Please note that this ordering ignores the @emph{results} of required
+tests, thus the test @file{foo-execute.test} is run even if the test
+@file{foo-compile.test} failed or was skipped beforehand. Further,
+please note that specifying such dependencies currently works only for
+tests that end in one of the suffixes listed in @code{TEST_EXTENSIONS}.
+
+Tests without such specified dependencies may be run concurrently with
+parallel @command{make -j@var{N}}, so be sure they are prepared for
+concurrent execution.
+
+@cindex Unit tests
+@c Keep in sync with 'parallel-tests-extra-programs.test'.
+The combination of lazy test execution and correct dependencies between
+tests and their sources may be exploited for efficient unit testing
+during development. To further speed up the edit-compile-test cycle, it
+may even be useful to specify compiled programs in @code{EXTRA_PROGRAMS}
+instead of with @code{check_PROGRAMS}, as the former allows intertwined
+compilation and test execution (but note that @code{EXTRA_PROGRAMS} are
+not cleaned automatically, @pxref{Uniform}).
+
+The variables @code{TESTS} and @code{XFAIL_TESTS} may contain
+conditional parts as well as configure substitutions. In the latter
+case, however, certain restrictions apply: substituted test names
+must end with a nonempty test suffix like @file{.test}, so that one of
+the inference rules generated by @command{automake} can apply. For
+literal test names, @command{automake} can generate per-target rules
+to avoid this limitation.
+
+Please note that it is currently not possible to use @code{$(srcdir)/}
+or @code{$(top_srcdir)/} in the @code{TESTS} variable. This technical
+limitation is necessary to avoid generating test logs in the source tree
+and has the unfortunate consequence that it is not possible to specify
+distributed tests that are themselves generated by means of explicit
+rules, in a way that is portable to all @command{make} implementations
+(@pxref{Make Target Lookup,,, autoconf, The Autoconf Manual}, the
+semantics of FreeBSD and OpenBSD @command{make} conflict with this).
+In case of doubt you may want to require to use GNU @command{make},
+or work around the issue with inference rules to generate the tests.

+@node Overview of Custom Test Drivers Support
+@subsection Overview of Custom Test Drivers Support
+
+Starting from Automake version 1.12, the parallel test harness allows
+the package authors to use third-party custom test drivers, in case the
+default ones are inadequate for their purposes, or do not support their
+testing protocol of choice.
+
+A custom test driver is expected to properly run the test programs passed
+to it (including the command-line arguments passed to those programs, if
+any), to analyze their execution and outcome, to create the @file{.log}
+and @file{.trs} files associated to these test runs, and to display the test
+results on the console. It is responsibility of the author of the test
+driver to ensure that it implements all the above steps meaningfully and
+correctly; Automake isn't and can't be of any help here. On the other
+hand, the Automake-provided code for testsuite summary generation offers
+support for test drivers allowing several test results per test script,
+if they take care to register such results properly (@pxref{Log files
+generation and test results recording}).
+
+The exact details of how test scripts' results are to be determined and
+analyzed is left to the individual drivers. Some drivers might only
+consider the test script exit status (this is done for example by the
+default test driver used by the parallel test harness, described
+in the previous section). Other drivers might implement more complex and
+advanced test protocols, which might require them to parse and interpreter
+the output emitted by the test script they're running (examples of such
+protocols are TAP and SubUnit).
+
+It's very important to note that, even when using custom test drivers,
+most of the infrastructure described in the previous section about the
+parallel harness remains in place; this includes:
+
+@itemize
+@item
+list of test scripts defined in @code{TESTS}, and overridable at
+runtime through the redefinition of @code{TESTS} or @code{TEST_LOGS};
+@item
+concurrency through the use of @command{make}'s option @option{-j};
+@item
+per-test @file{.log} and @file{.trs} files, and generation of a summary
+@file{.log} file from them;
+@item
+@code{recheck} target, @code{RECHECK_LOGS} variable, and lazy reruns
+of tests;
+@item
+inter-test dependencies;
+@item
+support for @code{check_*} variables (@code{check_PROGRAMS},
+@code{check_LIBRARIES}, ...);
+@item
+use of @code{VERBOSE} environment variable to get verbose output on
+testsuite failures;
+@item
+definition and honoring of @code{TESTS_ENVIRONMENT},
+@code{AM_TESTS_ENVIRONMENT} and @code{AM_TESTS_FD_REDIRECT}
+variables;
+@item
+definition of generic and extension-specific @code{LOG_COMPILER} and
+@code{LOG_FLAGS} variables.
+@end itemize
+
+@noindent
+On the other hand, the exact semantics of how (and if)
+@option{color-tests}, @code{XFAIL_TESTS}, and hard errors are supported
+and handled is left to the individual test drivers.
+
+@c TODO: We should really add a working example in the doc/ directory,

+Custom testsuite drivers are declared by defining the make variables
+@code{LOG_DRIVER} or @code{@var{ext}_LOG_DRIVER} (where @var{ext} must
+be declared in @code{TEST_EXTENSIONS}). They must be defined to
+programs or scripts that will be used to drive the execution, logging,
+and outcome report of the tests with corresponding extensions (or of
+those with no registered extension in the case of @code{LOG_DRIVER}).
+Clearly, multiple distinct test drivers can be declared in the same
+@file{Makefile.am}. Note moreover that the @code{LOG_DRIVER} variables
+are @emph{not} a substitute for the @code{LOG_COMPILER} variables: the
+two sets of variables can, and often do, usefully and legitimately
+coexist.
+
+@c TODO: We should really be able to point to a clarifying example here!
+
+The developer-reserved variable @code{AM_LOG_DRIVER_FLAGS} and the
+user-reserved variable @code{LOG_DRIVER_FLAGS} can be used to define
+flags that will be passed to each invocation of @code{LOG_DRIVER},
+with the user-defined flags obviously taking precedence over the
+developer-reserved ones. Similarly, for each extension @var{ext}
+declared in @code{TEST_EXTENSIONS}, flags listed in
+@code{AM_@var{ext}_LOG_DRIVER_FLAGS} and
+@code{@var{ext}_LOG_DRIVER_FLAGS} will be passed to
+invocations of @code{@var{ext}_LOG_DRIVER}.

+@node API for Custom Test Drivers
+@subsection API for Custom Test Drivers
+
+Note that @emph{the APIs described here are still highly experimental},
+and will very likely undergo tightenings and likely also extensive changes
+in the future, to accommodate for new features or to satisfy additional
+portability requirements.
+
+The main characteristic of these APIs is that they are designed to share
+as much infrastructure, semantics, and implementation details as possible
+with the parallel test harness and its default driver.

+
+@node Command-line arguments for test drivers
+@subsubsection Command-line arguments for test drivers
+
+A custom driver can rely on various command-line options and arguments
+being passed to it automatically by the Automake's @option{parallel-tests}
+harness. It is @emph{mandatory} that it understands all of them (even
+if the exact interpretation of the associated semantics can legitimately
+change between a test driver and another, and even be a no-op in some
+drivers).
+
+@noindent
+Here is the list of options:
+
+@table @option
+@item --test-name=@var{NAME}
+The name of the test, with VPATH prefix (if any) removed. This can have a
+suffix and a directory component (as in e.g., @file{sub/foo.test}), and is
+mostly meant to be used in console reports about testsuite advancements and
+results (@pxref{Testsuite progress output}).
+@item --log-file=@file{@var{PATH}.log}
+The @file{.log} file the test driver must create (@pxref{Basics of
+test metadata}). If it has a directory component (as in e.g.,
+@file{sub/foo.log}), the test harness will ensure that such directory
+exists @emph{before} the test driver is called.
+@item --trs-file=@file{@var{PATH}.trs}
+The @file{.trs} file the test driver must create (@pxref{Basics of
+test metadata}). If it has a directory component (as in e.g.,
+@file{sub/foo.trs}), the test harness will ensure that such directory
+exists @emph{before} the test driver is called.
+@item --color-tests=@{yes|no@}
+Whether the console output should be colorized or not (@pxref{Simple
+tests and color-tests}, to learn when this option gets activated and
+when it doesn't).
+@item --expect-failure=@{yes|no@}
+Whether the tested program is expected to fail.
+@item --enable-hard-errors=@{yes|no@}
+Whether ``hard errors'' in the tested program should be treated differently
+from normal failures or not (the default should be @code{yes}). The exact
+meaning of ``hard error'' is highly dependent from the test protocols or
+conventions in use.
+@item --
+Explicitly terminate the list of options.
+@end table
+
+@noindent
+The first non-option argument passed to the test driver is the program to
+be run, and all the following ones are command-line options and arguments
+for this program.
+
+Note that the exact semantics attached to the @option{--color-tests},
+@option{--expect-failure} and @option{--enable-hard-errors} options are
+left up to the individual test drivers. Still, having a behaviour
+compatible or at least similar to that provided by the default
+@option{parallel-tests} driver is advised, as that would offer a better
+consistency and a more pleasant user experience.
+
+@node Log files generation and test results recording
+@subsubsection Log files generation and test results recording
+
+The test driver must correctly generate the files specified by the
+@option{--log-file} and @option{--trs-file} option (even when the tested
+program fails or crashes).
+
+The @file{.log} file should ideally contain all the output produced by the
+tested program, plus optionally other information that might facilitate
+debugging or analysis of bug reports. Apart from that, its format is
+basically free.
+
+The @file{.trs} file is used to register some metadata through the use
+of custom reStructuredText fields. This metadata is expected to be
+employed in various ways by the parallel test harness; for example, to
+count the test results when printing the testsuite summary, or to decide
+which tests to re-run upon @command{make reheck}. Unrecognized metadata
+in a @file{.trs} file is currently ignored by the harness, but this might
+change in the future. The list of currently recognized metadata follows.
+
+@table @code
+
+@item :test-result:
+@cindex Register test result
+@cindex Register test case result
+@cindex Test result, registering
+@cindex Test case result, registering
+@cindex @code{:test-result:}
+@cindex reStructuredText field, @code{:test-result:}
+The test driver must use this field to register the results of @emph{each}
+test case run by a test script file. Several @code{:test-result:} fields
+can be present in the same @file{.trs} file; this is done in order to
+support test protocols that allow a single test script to run more test
+cases.
+
+@c Keep this in sync with lib/am/check-am:$(TEST_SUITE_LOG).
+The only recognized test results are currently @code{PASS}, @code{XFAIL},
+@code{SKIP}, @code{FAIL}, @code{XPASS} and @code{ERROR}. These results,
+when declared with @code{:test-result:}, can be optionally followed by
+text holding the name and/or a brief description of the corresponding
+test; the @option{parallel-tests} harness will ignore such extra text when
+generating @file{test-suite.log} and preparing the testsuite summary.
+

+@node Testsuite progress output
+@subsubsection Testsuite progress output
+
+A custom test driver also has the task of displaying, on the standard
+output, the test results as soon as they become available. Depending on
+the protocol in use, it can also display the reasons for failures and
+skips, and, more generally, any useful diagnostic output (but remember
+that each line on the screen is precious, so that cluttering the screen
+with overly verbose information is bad idea). The exact format of this
+progress output is left up to the test driver; in fact, a custom test
+driver might @emph{theoretically} even decide not to do any such report,
+leaving it all to the testsuite summary (that would be a very lousy idea,
+of course, and serves only to illustrate the flexibility that is
+granted here).
+
+Remember that consistency is good; so, if possible, try to be consistent
+with the output of the built-in Automake test drivers, providing a similar
+``look & feel''. In particular, the testsuite progress output should be
+colorized when the @option{--color-tests} is passed to the driver. On the
+other end, if you are using a known and widespread test protocol with
+well-established implementations, being consistent with those
+implementations' output might be a good idea too.
+
+@c TODO: Give an example, maybe inspired to py.test-style output.
+@c TODO: That is a good idea because it shows a test driver that allows

+@node Introduction to TAP
+@subsection Introduction to TAP
+
+TAP, the Test Anything Protocol, is a simple text-based interface between
+testing modules or programs and a test harness. The tests (also called
+``TAP producers'' in this context) write test results in a simple format
+on standard output; a test harness (also called ``TAP consumer'') will
+parse and interpret these results, and properly present them to the user,
+and/or register them for later analysis. The exact details of how this
+is accomplished can vary among different test harnesses. The Automake
+parallel harness will present the results on the console in the usual
+fashion (@pxref{Testsuite progress on console}), and will use the
+@file{.trs} files (@pxref{Basics of test metadata}) to store the test
+results and related metadata. Apart from that, it will try to remain
+as much compatible as possible with pre-existing and widespread utilities,
+such as the @uref{http://search.cpan.org/~andya/Test-Harness/bin/prove,
+@command{prove} utility}, at least for the simpler usages.
+
+TAP started its life as part of the test harness for Perl, but today
+it has been (mostly) standardized, and has various independent
+implementations in different languages; among them, C, C++, Perl,
+Python, PHP, and Java. For a semi-official specification of the
+TAP protocol, please refer to the documentation of
+@uref{http://search.cpan.org/~petdance/Test-Harness/lib/Test/Harness/TAP.pod,
+ @samp{Test::Harness::TAP}}.
+
+The most relevant real-world usages of TAP are obviously in the testsuites
+of @command{perl} and of many perl modules. Still, also other important
+third-party packages, such as @uref{http://git-scm.com/, @command{git}},
+use TAP in their testsuite.
+
+@node Use TAP with the Automake test harness
+@subsection Use TAP with the Automake test harness
+
+Currently, the TAP driver that comes with Automake requires some by-hand
+steps on the developer's part (this situation should hopefully be improved
+in future Automake versions). You'll have to grab the @file{tap-driver.sh}
+script from the Automake distribution by hand, copy it in your source tree,
+add a call to @code{AC_PROG_AWK} in @file{configure.ac} to search for a
+proper awk program, and use the Automake support for third-party test
+drivers to instruct the harness to use the @file{tap-driver.sh} script
+and that awk program to run your TAP-producing tests. See the example
+below for clarification.
+
+Apart from the options common to all the Automake test drivers
+(@pxref{Command-line arguments for test drivers}), the @file{tap-driver.sh}
+supports the following options, whose names are chosen for enhanced
+compatibility with the @command{prove} utility.
+
+@table @option
+@c Keep in sync with 'tap-exit.test' and 'tap-signal.tap'.
+@item --ignore-exit
+Causes the test driver to ignore the exit status of the test scripts;
+by default, the driver will report an error if the script exits with a
+non-zero status. This option has effect also on non-zero exit statuses
+due to termination by a signal.
+@item --comments
+Instruct the test driver to display TAP diagnostic (i.e., lines beginning
+with the @samp{#} character) in the testsuite progress output too; by
+default, TAP diagnostic is only copied to the @file{.log} file.
+@item --no-comments
+Revert the effects of @option{--comments}.
+@item --merge
+Instruct the test driver to merge the test scripts' standard error into
+their standard output. This is necessary if you want to ensure that
+diagnostics from the test scripts are displayed in the correct order
+relative to test results; this can be of great help in debugging
+(especially if your test scripts are shell scripts run with shell
+tracing active). As a downside, this option might cause the test
+harness to get confused if anything that appears on standard error
+looks like a test result.
+@item --no-merge
+Revert the effects of @option{--merge}.
+@item --diagnostic-string=@var{STRING}
+Change the string that introduces TAP diagnostic from the default value
+of ``@code{#}'' to @code{@var{STRING}}. This can be useful if your
+TAP-based test scripts produce verbose output on which they have limited
+control (because, say, the output comes from other tools invoked in the
+scripts), and it might contain text that gets spuriously interpreted as
+TAP diagnostic: such an issue can be solved by redefining the string that
+activates TAP diagnostic to a value you know won't appear by chance in
+the tests' output. Note however that this feature is non-standard, as
+the ``official'' TAP protocol does not allow for such a customization; so
+don't use it if you can avoid it.

+@node Incompatibilities with other TAP parsers and drivers
+@subsection Incompatibilities with other TAP parsers and drivers
+
+For implementation or historical reasons, the TAP driver and harness as
+implemented by Automake have some minors incompatibilities with the
+mainstream versions, which you should be aware of.
+
+@itemize @bullet
+@item
+A @code{Bail out!} directive doesn't stop the whole testsuite, but only
+the test script it occurs in. This doesn't follow TAP specifications,
+but on the other hand it maximizes compatibility (and code sharing) with
+the ``hard error'' concept of the default @option{parallel-tests} driver.
+@item
+The @code{version} and @code{pragma} directives are not supported.
+@item
+The @option{--diagnostic-string} option of our driver allows to modify
+the string that introduces TAP diagnostic from the default value
+of ``@code{#}''. The standard TAP protocol has currently no way to
+allow this, so if you use it your diagnostic will be lost to more
+compliant tools like @command{prove} and @code{Test::Harness}

+And there are probably some other small and yet undiscovered
+incompatibilities, especially in corner cases or with rare usages.

+
+If @uref{ftp://ftp.gnu.org/gnu/dejagnu/, @command{dejagnu}} appears in
+@code{AUTOMAKE_OPTIONS}, then a @command{dejagnu}-based test suite is
+assumed. The variable @code{DEJATOOL} is a list of names that are
+passed, one at a time, as the @option{--tool} argument to
+@command{runtest} invocations; it defaults to the name of the package.
+
+The variable @code{RUNTESTDEFAULTFLAGS} holds the @option{--tool} and
+@option{--srcdir} flags that are passed to dejagnu by default; this can be
+overridden if necessary.
+@vindex RUNTESTDEFAULTFLAGS
+
+The variables @code{EXPECT} and @code{RUNTEST} can
+also be overridden to provide project-specific values. For instance,
+you will need to do this if you are testing a compiler toolchain,
+because the default values do not take into account host and target
+names.
+@opindex dejagnu
+@vindex DEJATOOL
+@vindex EXPECT
+@vindex RUNTEST
+
+The contents of the variable @code{RUNTESTFLAGS} are passed to the
+@code{runtest} invocation. This is considered a ``user variable''
+(@pxref{User Variables}). If you need to set @command{runtest} flags in
+@file{Makefile.am}, you can use @code{AM_RUNTESTFLAGS} instead.
+@vindex RUNTESTFLAGS
+@vindex AM_RUNTESTFLAGS
+
+@cindex @file{site.exp}
+Automake will generate rules to create a local @file{site.exp} file,
+defining various variables detected by @command{configure}. This file
+is automatically read by DejaGnu. It is OK for the user of a package
+to edit this file in order to tune the test suite. However this is
+not the place where the test suite author should define new variables:
+this should be done elsewhere in the real test suite code.
+Especially, @file{site.exp} should not be distributed.
+
+Still, if the package author has legitimate reasons to extend
+@file{site.exp} at @command{make} time, he can do so by defining
+the variable @code{EXTRA_DEJAGNU_SITE_CONFIG}; the files listed
+there will be considered @file{site.exp} prerequisites, and their
+content will be appended to it (in the same order in which they
+appear in @code{EXTRA_DEJAGNU_SITE_CONFIG}). Note that files are
+@emph{not} distributed by default.

+@node Rebuilding
+@chapter Rebuilding Makefiles
+@cindex rebuild rules
+
+Automake generates rules to automatically rebuild @file{Makefile}s,
+@file{configure}, and other derived files like @file{Makefile.in}.
+
+@acindex AM_MAINTAINER_MODE
+If you are using @code{AM_MAINTAINER_MODE} in @file{configure.ac}, then
+these automatic rebuilding rules are only enabled in maintainer mode.
+
+@vindex ACLOCAL_AMFLAGS
+Sometimes you need to run @command{aclocal} with an argument like
+@option{-I} to tell it where to find @file{.m4} files. Since
+sometimes @command{make} will automatically run @command{aclocal}, you
+need a way to specify these arguments. You can do this by defining
+@code{ACLOCAL_AMFLAGS}; this holds arguments that are passed verbatim
+to @command{aclocal}. This variable is only useful in the top-level
+@file{Makefile.am}.
+
+@vindex CONFIG_STATUS_DEPENDENCIES
+@vindex CONFIGURE_DEPENDENCIES
+@cindex @file{version.sh}, example
+@cindex @file{version.m4}, example
+
+Sometimes it is convenient to supplement the rebuild rules for
+@file{configure} or @file{config.status} with additional dependencies.
+The variables @code{CONFIGURE_DEPENDENCIES} and
+@code{CONFIG_STATUS_DEPENDENCIES} can be used to list these extra
+dependencies. These variables should be defined in all
+@file{Makefile}s of the tree (because these two rebuild rules are
+output in all them), so it is safer and easier to @code{AC_SUBST} them
+from @file{configure.ac}. For instance, the following statement will
+cause @file{configure} to be rerun each time @file{version.sh} is
+changed.
+
+@example
+AC_SUBST([CONFIG_STATUS_DEPENDENCIES], ['$(top_srcdir)/version.sh'])
+@end example
+
+@noindent
+Note the @samp{$(top_srcdir)/} in the file name. Since this variable
+is to be used in all @file{Makefile}s, its value must be sensible at
+any level in the build hierarchy.
+
+Beware not to mistake @code{CONFIGURE_DEPENDENCIES} for
+@code{CONFIG_STATUS_DEPENDENCIES}.
+
+@code{CONFIGURE_DEPENDENCIES} adds dependencies to the
+@file{configure} rule, whose effect is to run @command{autoconf}. This
+variable should be seldom used, because @command{automake} already tracks
+@code{m4_include}d files. However it can be useful when playing
+tricky games with @code{m4_esyscmd} or similar non-recommendable
+macros with side effects.
+
+@code{CONFIG_STATUS_DEPENDENCIES} adds dependencies to the
+@file{config.status} rule, whose effect is to run @file{configure}.
+This variable should therefore carry any non-standard source that may
+be read as a side effect of running @command{configure}, like @file{version.sh}
+in the example above.
+
+Speaking of @file{version.sh} scripts, we recommend against them
+today. They are mainly used when the version of a package is updated
+automatically by a script (e.g., in daily builds). Here is what some
+old-style @file{configure.ac}s may look like:
+
+@example
+AC_INIT
+. $srcdir/version.sh
+AM_INIT_AUTOMAKE([name], $VERSION_NUMBER)
+@dots{}
+@end example
+
+@noindent
+Here, @file{version.sh} is a shell fragment that sets
+@code{VERSION_NUMBER}. The problem with this example is that
+@command{automake} cannot track dependencies (listing @file{version.sh}
+in @command{CONFIG_STATUS_DEPENDENCIES}, and distributing this file is up
+to the user), and that it uses the obsolete form of @code{AC_INIT} and
+@code{AM_INIT_AUTOMAKE}. Upgrading to the new syntax is not
+straightforward, because shell variables are not allowed in
+@code{AC_INIT}'s arguments. We recommend that @file{version.sh} be
+replaced by an M4 file that is included by @file{configure.ac}:
+
+@example
+m4_include([version.m4])
+AC_INIT([name], VERSION_NUMBER)
+AM_INIT_AUTOMAKE
+@dots{}
+@end example
+
+@noindent
+Here @file{version.m4} could contain something like
+@samp{m4_define([VERSION_NUMBER], [1.2])}. The advantage of this
+second form is that @command{automake} will take care of the
+dependencies when defining the rebuild rule, and will also distribute
+the file automatically. An inconvenience is that @command{autoconf}
+will now be rerun each time the version number is bumped, when only
+@file{configure} had to be rerun in the previous setup.

+@end menu
+
+@node Options generalities
+@section Options generalities
+
+Various features of Automake can be controlled by options. Except where
+noted otherwise, options can be specified in one of several ways. Most
+options can be applied on a per-@file{Makefile} basis when listed in a
+special @file{Makefile} variable named @code{AUTOMAKE_OPTIONS}. Some
+of these options only make sense when specified in the toplevel
+@file{Makefile.am} file. Options are applied globally to all processed
+@file{Makefile} files when listed in the first argument of
+@code{AM_INIT_AUTOMAKE} in @file{configure.ac}, and some options which
+require changes to the @command{configure} script can only be specified
+there. These are annotated below.
+
+As a general rule, options specified in @code{AUTOMAKE_OPTIONS} take
+precedence over those specified in @code{AM_INIT_AUTOMAKE}, which in
+turn take precedence over those specified on the command line.
+
+Also, some care must be taken about the interactions among strictness
+level and warning categories. As a general rule, strictness-implied
+warnings are overridden by those specified by explicit options. For
+example, even if @samp{portability} warnings are disabled by default
+in @option{foreign} strictness, an usage like this will end up enabling
+them:
+
+@example
+AUTOMAKE_OPTIONS = -Wportability foreign
+@end example
+
+However, a strictness level specified in a higher-priority context
+will override all the explicit warnings specified in a lower-priority
+context. For example, if @file{configure.ac} contains:
+
+@example
+AM_INIT_AUTOMAKE([-Wportability])
+@end example
+
+@noindent
+and @file{Makefile.am} contains:
+
+@example
+AUTOMAKE_OPTIONS = foreign
+@end example
+
+@noindent
+then @samp{portability} warnings will be @emph{disabled} in
+@file{Makefile.am}.

+
+@item @option{no-define}
+@cindex Option, @option{no-define}
+@opindex no-define
+This option is meaningful only when passed as an argument to

+@item @option{no-dependencies}
+@cindex Option, @option{no-dependencies}
+@opindex no-dependencies
+This is similar to using @option{--ignore-deps} on the command line,
+but is useful for those situations where you don't have the necessary
+bits to make automatic dependency tracking work
+(@pxref{Dependencies}). In this case the effect is to effectively
+disable automatic dependency tracking.
+
+@item @option{no-dist}
+@cindex Option, @option{no-dist}
+@opindex no-dist
+Don't emit any code related to @code{dist} target. This is useful
+when a package has its own method for making distributions.
+
+@item @option{no-dist-gzip}
+@cindex Option, @option{no-dist-gzip}
+@opindex no-dist-gzip
+Do not hook @code{dist-gzip} to @code{dist}.
+@trindex no-dist-gzip
+
+@item @option{no-exeext}
+@cindex Option, @option{no-exeext}
+@opindex no-exeext
+If your @file{Makefile.am} defines a rule for target @code{foo}, it
+will override a rule for a target named @samp{foo$(EXEEXT)}. This is
+necessary when @code{EXEEXT} is found to be empty. However, by
+default @command{automake} will generate an error for this use. The
+@option{no-exeext} option will disable this error. This is intended for
+use only where it is known in advance that the package will not be
+ported to Windows, or any other operating system using extensions on
+executables.
+

+@option{gnu} strictness and above.
+@trindex info
+@trindex install-info
+
+@item @option{no-installman}
+@cindex Option, @option{no-installman}
+@opindex no-installman
+The generated @file{Makefile.in} will not cause man pages to be

+@trindex install-man
+
+@item @option{nostdinc}
+@cindex Option, @option{nostdinc}

+Test Harness}, for more information). This is still the default for the
+moment.
+
+@item @option{readme-alpha}
+@cindex Option, @option{readme-alpha}
+@opindex readme-alpha
+If this release is an alpha release, and the file @file{README-alpha}
+exists, then it will be added to the distribution. If this option is
+given, version numbers are expected to follow one of two forms. The
+first form is @samp{@var{major}.@var{minor}.@var{alpha}}, where each
+element is a number; the final period and number should be left off for
+non-alpha releases. The second form is
+@samp{@var{major}.@var{minor}@var{alpha}}, where @var{alpha} is a
+letter; it should be omitted for non-alpha releases.
+
+@item @option{silent-rules}
+@cindex Option, @option{silent-rules}
+@opindex silent-rules
+Enable less verbose build rules. This can be used to let build rules
+output status lines of the form:
+@example
+GEN @var{output-file}
+ CC @var{object-file}
+@end example
+@noindent
+instead of printing the command that will be executed to update
+@var{output-file} or to compile @var{object-file}. It can also
+silence @command{libtool} output.

+@opindex std-options
+
+Make the @code{installcheck} rule check that installed scripts and
+programs support the @option{--help} and @option{--version} options.
+This also provides a basic check that the program's
+run-time dependencies are satisfied after installation.
+
+@vindex AM_INSTALLCHECK_STD_OPTIONS_EXEMPT
+In a few situations, programs (or scripts) have to be exempted from this
+test. For instance, @command{false} (from GNU coreutils) is never
+successful, even for @option{--help} or @option{--version}. You can list
+such programs in the variable @code{AM_INSTALLCHECK_STD_OPTIONS_EXEMPT}.
+Programs (not scripts) listed in this variable should be suffixed by
+@samp{$(EXEEXT)} for the sake of Windows or OS/2. For instance, suppose we
+build @file{false} as a program but @file{true.sh} as a script, and that
+neither of them support @option{--help} or @option{--version}:
+
+@example
+AUTOMAKE_OPTIONS = std-options
+bin_PROGRAMS = false ...
+bin_SCRIPTS = true.sh ...
+AM_INSTALLCHECK_STD_OPTIONS_EXEMPT = false$(EXEEXT) true.sh
+@end example
+
+@item @option{subdir-objects}
+@cindex Options, @option{subdir-objects}
+@opindex subdir-objects
+If this option is specified, then objects are placed into the
+subdirectory of the build directory corresponding to the subdirectory of
+the source file. For instance, if the source file is
+@file{subdir/file.cxx}, then the output file would be
+@file{subdir/file.o}.
+
+In order to use this option with C sources, you should add

+
+These three mutually exclusive options select the tar format to use
+when generating tarballs with @samp{make dist}. (The tar file created
+is then compressed according to the set of @option{no-dist-gzip},
+@option{dist-bzip2}, @option{dist-lzip}, @option{dist-xz} and
+@option{dist-tarZ} options in use.)
+
+These options must be passed as arguments to @code{AM_INIT_AUTOMAKE}
+(@pxref{Macros}) because they can require additional configure checks.
+Automake will complain if it sees such options in an
+@code{AUTOMAKE_OPTIONS} variable.
+
+@option{tar-v7} selects the old V7 tar format. This is the historical
+default. This antiquated format is understood by all tar
+implementations and supports file names with up to 99 characters. When
+given longer file names some tar implementations will diagnose the
+problem while other will generate broken tarballs or use non-portable
+extensions. Furthermore, the V7 format cannot store empty
+directories. When using this format, consider using the
+@option{filename-length-max=99} option to catch file names too long.
+
+@option{tar-ustar} selects the ustar format defined by POSIX
+1003.1-1988. This format is believed to be old enough to be portable.
+It fully supports empty directories. It can store file names with up
+to 256 characters, provided that the file name can be split at
+directory separator in two parts, first of them being at most 155
+bytes long. So, in most cases the maximum file name length will be
+shorter than 256 characters. However you may run against broken tar
+implementations that incorrectly handle file names longer than 99
+characters (please report them to @email{@value{PACKAGE_BUGREPORT}} so we
+can document this accurately).
+
+@option{tar-pax} selects the new pax interchange format defined by POSIX
+1003.1-2001. It does not limit the length of file names. However,
+this format is very young and should probably be restricted to
+packages that target only very modern platforms. There are moves to
+change the pax format in an upward-compatible way, so this option may
+refer to a more recent version in the future.
+
+@xref{Formats, , Controlling the Archive Format, tar, GNU Tar}, for
+further discussion about tar formats.
+
+@command{configure} knows several ways to construct these formats. It
+will not abort if it cannot find a tool up to the task (so that the
+package can still be built), but @samp{make dist} will fail.
+
+@item @var{version}
+@cindex Option, @var{version}
+A version number (e.g., @samp{0.30}) can be specified. If Automake is not
+newer than the version specified, creation of the @file{Makefile.in}
+will be suppressed.
+
+@item @option{-W@var{category}} or @option{--warnings=@var{category}}
+@cindex Option, warnings
+@cindex Option, @option{-W@var{category}}
+@cindex Option, @option{--warnings=@var{category}}
+These options behave exactly like their command-line counterpart
+(@pxref{automake Invocation}). This allows you to enable or disable some
+warning categories on a per-file basis. You can also setup some warnings
+for your entire project; for instance, try @samp{AM_INIT_AUTOMAKE([-Wall])}
+in your @file{configure.ac}.
+
+@end table
+
+Unrecognized options are diagnosed by @command{automake}.
+
+If you want an option to apply to all the files in the tree, you can use
+the @code{AM_INIT_AUTOMAKE} macro in @file{configure.ac}.

+@node Miscellaneous
+@chapter Miscellaneous Rules
+
+There are a few rules and variables that didn't fit anywhere else.
+
+@menu
+* Tags:: Interfacing to cscope, etags and mkid
+* Suffixes:: Handling new file extensions
+@end menu
+
+
+@node Tags
+@section Interfacing to @command{etags}
+
+@cindex @file{TAGS} support
+
+Automake will generate rules to generate @file{TAGS} files for use with
+GNU Emacs under some circumstances.
+
+@trindex tags
+If any C, C++ or Fortran 77 source code or headers are present, then
+@code{tags} and @code{TAGS} rules will be generated for the directory.
+All files listed using the @code{_SOURCES}, @code{_HEADERS}, and
+@code{_LISP} primaries will be used to generate tags. Note that
+generated source files that are not distributed must be declared in
+variables like @code{nodist_noinst_HEADERS} or
+@code{nodist_@var{prog}_SOURCES} or they will be ignored.
+
+A @code{tags} rule will be output at the topmost directory of a
+multi-directory package. When run from this topmost directory,
+@samp{make tags} will generate a @file{TAGS} file that includes by
+reference all @file{TAGS} files from subdirectories.
+
+The @code{tags} rule will also be generated if the variable
+@code{ETAGS_ARGS} is defined. This variable is intended for use in
+directories that contain taggable source that @command{etags} does
+not understand. The user can use the @code{ETAGSFLAGS} to pass
+additional flags to @command{etags}; @code{AM_ETAGSFLAGS} is also
+available for use in @file{Makefile.am}.
+@vindex ETAGS_ARGS
+@vindex ETAGSFLAGS
+@vindex AM_ETAGSFLAGS
+
+Here is how Automake generates tags for its source, and for nodes in its
+Texinfo file:
+
+@example
+ETAGS_ARGS = automake.in --lang=none \
+ --regex='/^@@node[ \t]+\([^,]+\)/\1/' automake.texi
+@end example
+
+If you add file names to @code{ETAGS_ARGS}, you will probably also
+want to define @code{TAGS_DEPENDENCIES}. The contents of this variable
+are added directly to the dependencies for the @code{tags} rule.
+@vindex TAGS_DEPENDENCIES
+
+Automake also generates a @code{ctags} rule that can be used to
+build @command{vi}-style @file{tags} files. The variable @code{CTAGS}
+is the name of the program to invoke (by default @command{ctags});
+@code{CTAGSFLAGS} can be used by the user to pass additional flags,
+and @code{AM_CTAGSFLAGS} can be used by the @file{Makefile.am}.
+
+@trindex id
+Automake will also generate an @code{ID} rule that will run
+@command{mkid} on the source. This is only supported on a
+directory-by-directory basis.
+
+Similarly, the @code{cscope} rule will create a list of all the source
+files in the tree and run @command{cscope} to build an inverted index
+database. The variable @code{CSCOPE} is the name of the program to invoke
+(by default @command{cscope}); @code{CSCOPEFLAGS} and
+@code{CSCOPE_ARGS} can be used by the user to pass additional flags and
+file names respectively, while @code{AM_CSCOPEFLAGS} can be used by the
+@file{Makefile.am}. Note that, currently, the Automake-provided
+@code{cscope} support, when used in a VPATH build, might not work well
+with non-GNU make implementations (especially with make implementations
+performing @ref{Automatic Rule Rewriting, , VPATH rewrites, autoconf,
+The Autoconf Manual}).
+
+Finally, Automake also emits rules to support the
+@uref{http://www.gnu.org/software/global/, GNU Global Tags program}.
+The @code{GTAGS} rule runs Global Tags and puts the
+result in the top build directory. The variable @code{GTAGS_ARGS}
+holds arguments that are passed to @command{gtags}.
+@vindex GTAGS_ARGS
+
+
+@node Suffixes
+@section Handling new file extensions
+
+@cindex Adding new @code{SUFFIXES}
+@cindex @code{SUFFIXES}, adding
+@vindex SUFFIXES
+
+It is sometimes useful to introduce a new implicit rule to handle a file
+type that Automake does not know about.
+
+For instance, suppose you had a compiler that could compile @file{.foo}
+files to @file{.o} files. You would simply define a suffix rule for
+your language:
+
+@example
+.foo.o:
+ foocc -c -o $@@ $<
+@end example
+
+Then you could directly use a @file{.foo} file in a @code{_SOURCES}
+variable and expect the correct results:
+
+@example
+bin_PROGRAMS = doit
+doit_SOURCES = doit.foo
+@end example
+
+This was the simpler and more common case. In other cases, you will
+have to help Automake to figure out which extensions you are defining your
+suffix rule for. This usually happens when your extension does not
+start with a dot. Then, all you have to do is to put a list of new
+suffixes in the @code{SUFFIXES} variable @strong{before} you define your
+implicit rule.
+
+For instance, the following definition prevents Automake from misinterpreting
+the @samp{.idlC.cpp:} rule as an attempt to transform @file{.idlC} files into
+@file{.cpp} files.
+
+@c Keep in sync with suffix7.sh
+@example
+SUFFIXES = .idl C.cpp
+.idlC.cpp:
+ # whatever
+@end example
+
+As you may have noted, the @code{SUFFIXES} variable behaves like the
+@code{.SUFFIXES} special target of @command{make}. You should not touch
+@code{.SUFFIXES} yourself, but use @code{SUFFIXES} instead and let
+Automake generate the suffix list for @code{.SUFFIXES}. Any given
+@code{SUFFIXES} go at the start of the generated suffixes list, followed
+by Automake generated suffixes not already in the list.
+
+@node Include
+@chapter Include
+
+@cmindex include
+@cindex Including @file{Makefile} fragment
+@cindex @file{Makefile} fragment, including
+
+Automake supports an @code{include} directive that can be used to
+include other @file{Makefile} fragments when @command{automake} is run.
+Note that these fragments are read and interpreted by @command{automake},
+not by @command{make}. As with conditionals, @command{make} has no idea that
+@code{include} is in use.
+
+There are two forms of @code{include}:
+
+@table @code
+@item include $(srcdir)/file
+Include a fragment that is found relative to the current source
+directory.
+
+@item include $(top_srcdir)/file
+Include a fragment that is found relative to the top source directory.
+@end table
+
+Note that if a fragment is included inside a conditional, then the
+condition applies to the entire contents of that fragment.
+
+Makefile fragments included this way are always distributed because
+they are needed to rebuild @file{Makefile.in}.
+
+@node Conditionals
+@chapter Conditionals
+
+@cindex Conditionals
+
+Automake supports a simple type of conditionals.
+
+These conditionals are not the same as conditionals in
+GNU Make. Automake conditionals are checked at configure time by the
+@file{configure} script, and affect the translation from
+@file{Makefile.in} to @file{Makefile}. They are based on options passed
+to @file{configure} and on results that @file{configure} has discovered
+about the host system. GNU Make conditionals are checked at @command{make}
+time, and are based on variables passed to the make program or defined
+in the @file{Makefile}.
+
+Automake conditionals will work with any make program.

+
+@acindex AM_CONDITIONAL
+Before using a conditional, you must define it by using
+@code{AM_CONDITIONAL} in the @file{configure.ac} file (@pxref{Macros}).
+
+@defmac AM_CONDITIONAL (@var{conditional}, @var{condition})
+The conditional name, @var{conditional}, should be a simple string
+starting with a letter and containing only letters, digits, and
+underscores. It must be different from @samp{TRUE} and @samp{FALSE}
+that are reserved by Automake.
+
+The shell @var{condition} (suitable for use in a shell @code{if}
+statement) is evaluated when @command{configure} is run. Note that you
+must arrange for @emph{every} @code{AM_CONDITIONAL} to be invoked every
+time @command{configure} is run. If @code{AM_CONDITIONAL} is run
+conditionally (e.g., in a shell @code{if} statement), then the result
+will confuse @command{automake}.
+@end defmac
+
+@cindex @option{--enable-debug}, example
+@cindex Example conditional @option{--enable-debug}
+@cindex Conditional example, @option{--enable-debug}
+
+Conditionals typically depend upon options that the user provides to
+the @command{configure} script. Here is an example of how to write a
+conditional that is true if the user uses the @option{--enable-debug}
+option.
+
+@example
+AC_ARG_ENABLE([debug],
+[ --enable-debug Turn on debugging],
+[case "$@{enableval@}" in
+ yes) debug=true ;;
+ no) debug=false ;;
+ *) AC_MSG_ERROR([bad value $@{enableval@} for --enable-debug]) ;;
+esac],[debug=false])
+AM_CONDITIONAL([DEBUG], [test x$debug = xtrue])
+@end example
+
+Here is an example of how to use that conditional in @file{Makefile.am}:
+
+@cmindex if
+@cmindex endif
+@cmindex else
+
+@example
+if DEBUG
+DBG = debug
+else
+DBG =
+endif
+noinst_PROGRAMS = $(DBG)
+@end example
+
+This trivial example could also be handled using @code{EXTRA_PROGRAMS}
+(@pxref{Conditional Programs}).
+
+You may only test a single variable in an @code{if} statement, possibly
+negated using @samp{!}. The @code{else} statement may be omitted.
+Conditionals may be nested to any depth. You may specify an argument to
+@code{else} in which case it must be the negation of the condition used
+for the current @code{if}. Similarly you may specify the condition
+that is closed on the @code{endif} line:
+
+@example
+if DEBUG
+DBG = debug
+else !DEBUG
+DBG =
+endif !DEBUG
+@end example
+
+@noindent
+Unbalanced conditions are errors. The @code{if}, @code{else}, and
+@code{endif} statements should not be indented, i.e., start on column
+one.
+
+The @code{else} branch of the above two examples could be omitted,
+since assigning the empty string to an otherwise undefined variable
+makes no difference.
+
+@acindex AM_COND_IF
+In order to allow access to the condition registered by
+@code{AM_CONDITIONAL} inside @file{configure.ac}, and to allow
+conditional @code{AC_CONFIG_FILES}, @code{AM_COND_IF} may be used:
+
+@defmac AM_COND_IF (@var{conditional}, @ovar{if-true}, @ovar{if-false})
+If @var{conditional} is fulfilled, execute @var{if-true}, otherwise
+execute @var{if-false}. If either branch contains @code{AC_CONFIG_FILES},
+it will cause @command{automake} to output the rules for the respective
+files only for the given condition.
+@end defmac
+
+@code{AM_COND_IF} macros may be nested when m4 quotation is used
+properly (@pxref{M4 Quotation, ,, autoconf, The Autoconf Manual}).
+
+@cindex Example conditional @code{AC_CONFIG_FILES}
+@cindex @code{AC_CONFIG_FILES}, conditional
+
+Here is an example of how to define a conditional config file:
+
+@example
+AM_CONDITIONAL([SHELL_WRAPPER], [test "x$with_wrapper" = xtrue])
+AM_COND_IF([SHELL_WRAPPER],
+ [AC_CONFIG_FILES([wrapper:wrapper.in])])
+@end example
+
+@node Limits of Conditionals
+@section Limits of Conditionals
+
+Conditionals should enclose complete statements like variables or
+rules definitions. Automake cannot deal with conditionals used inside
+a variable definition, for instance, and is not even able to diagnose
+this situation. The following example would not work:
+
+@example
+# This syntax is not understood by Automake
+AM_CPPFLAGS = \
+ -DFEATURE_A \
+if WANT_DEBUG
+ -DDEBUG \
+endif
+ -DFEATURE_B
+@end example
+
+However the intended definition of @code{AM_CPPFLAGS} can be achieved
+with
+
+@example
+if WANT_DEBUG
+ DEBUGFLAGS = -DDEBUG
+endif
+AM_CPPFLAGS = -DFEATURE_A $(DEBUGFLAGS) -DFEATURE_B
+@end example
+
+@noindent
+or
+
+@example
+AM_CPPFLAGS = -DFEATURE_A
+if WANT_DEBUG
+AM_CPPFLAGS += -DDEBUG
+endif
+AM_CPPFLAGS += -DFEATURE_B
+@end example

+
+@node Make verbosity
+@section Make is verbose by default
+
+Normally, when executing the set of rules associated with a target,
+@command{make} prints each rule before it is executed. This behaviour,
+while having been in place for a long time, and being even mandated by
+the POSIX standard, starkly violates the ``silence is golden'' UNIX
+principle@footnote{See also
+@uref{http://catb.org/~esr/writings/taoup/html/ch11s09.html}.}:
+
+@quotation
+When a program has nothing interesting or surprising to say, it should
+say nothing. Well-behaved Unix programs do their jobs unobtrusively,
+with a minimum of fuss and bother. Silence is golden.
+@end quotation
+
+In fact, while such verbosity of @command{make} can theoretically be
+useful to track bugs and understand reasons of failures right away, it
+can also hide warning and error messages from @command{make}-invoked
+tools, drowning them in a flood of uninteresting and seldom useful
+messages, and thus allowing them to go easily undetected.
+
+This problem can be very annoying, especially for developers, who usually
+know quite well what's going on behind the scenes, and for whom the
+verbose output from @command{make} ends up being mostly noise that hampers
+the easy detection of potentially important warning messages.
+
+@node Tricks For Silencing Make
+@section Standard and generic ways to silence make
+
+Here we describe some common idioms/tricks to obtain a quieter make
+output, with their relative advantages and drawbacks. In the next
+section (@ref{Automake silent-rules Option}) we'll see how Automake
+can help in this respect.
+
+@itemize @bullet
+
+@item @command{make -s}
+
+This simply causes @command{make} not to print @emph{any} rule before
+executing it.
+
+The @option{-s} flag is mandated by POSIX, universally supported, and
+its purpose and function are easy to understand.
+
+But it also has its serious limitations too. First of all, it embodies
+an ``all or nothing'' strategy, i.e., either everything is silenced, or
+nothing is; this lack of granularity can sometimes be a fatal flaw.
+Moreover, when the @option{-s} flag is used, the @command{make} output
+might turn out to be too much terse; in case of errors, the user won't
+be able to easily see what rule or command have caused them, or even,
+in case of tools with poor error reporting, what the errors were!
+
+@item @command{make >/dev/null || make}
+
+Apparently, this perfectly obeys the ``silence is golden'' rule: warnings
+from stderr are passed through, output reporting is done only in case of
+error, and in that case it should provide a verbose-enough report to allow
+an easy determination of the error location and causes.
+
+However, calling @command{make} two times in a row might hide errors
+(especially intermittent ones), or subtly change the expected semantic
+of the @command{make} calls --- things these which can clearly make
+debugging and error assessment very difficult.
+
+@item @command{make --no-print-directory}
+
+This is GNU @command{make} specific. When called with the
+@option{--no-print-directory} option, GNU @command{make} will disable
+printing of the working directory by invoked sub-@command{make}s (the
+well-known ``@i{Entering/Leaving directory ...}'' messages). This helps
+to decrease the verbosity of the output, but experience has shown that
+it can also often render debugging considerably harder in projects using
+deeply-nested @command{make} recursion.
+
+As an aside, notice that the @option{--no-print-directory} option is
+automatically activated if the @option{-s} flag is used.

+@node Automake silent-rules Option
+@section How Automake can help in silencing make
+
+The tricks and idioms for silencing @command{make} described in the
+previous section can be useful from time to time, but we've seen that
+they all have their serious drawbacks and limitations. That's why
+automake provides support for a more advanced and flexible way of
+obtaining quieter output from @command{make}: the @option{silent-rules}
+mode.
+
+@c TODO: Maybe describe in brief the precedent set by the build system
+@c of the Linux Kernel, from which Automake took inspiration ... Links?
+
+To give the gist of what @option{silent-rules} can do, here is a simple
+comparison between a typical @command{make} output (where silent rules
+are disabled) and one with silent rules enabled:
+
+@example
+% @kbd{cat Makefile.am}
+bin_PROGRAMS = foo
+foo_SOURCES = main.c func.c
+% @kbd{cat main.c}
+int main (void) @{ return func (); @} /* func used undeclared */
+% @kbd{cat func.c}
+int func (void) @{ int i; return i; @} /* i used uninitialized */
+
+@i{The make output is by default very verbose. This causes warnings
+from the compiler to be somewhat hidden, and not immediate to spot.}
+% @kbd{make CFLAGS=-Wall}
+gcc -DPACKAGE_NAME=\"foo\" -DPACKAGE_TARNAME=\"foo\" ...
+-DPACKAGE_STRING=\"foo\ 1.0\" -DPACKAGE_BUGREPORT=\"\" ...
+-DPACKAGE=\"foo\" -DVERSION=\"1.0\" -I. -Wall -MT main.o
+-MD -MP -MF .deps/main.Tpo -c -o main.o main.c

+mv -f .deps/main.Tpo .deps/main.Po
+gcc -DPACKAGE_NAME=\"foo\" -DPACKAGE_TARNAME=\"foo\" ...
+-DPACKAGE_STRING=\"foo\ 1.0\" -DPACKAGE_BUGREPORT=\"\" ...

+mv -f .deps/func.Tpo .deps/func.Po
+gcc -Wall -o foo main.o func.o
+
+@i{Clean up, so that we we can rebuild everything from scratch.}
+% @kbd{make clean}
+test -z "foo" || rm -f foo
+rm -f *.o
+
+@i{Silent rules enabled: the output is minimal but informative. In
+particular, the warnings from the compiler stick out very clearly.}
+% @kbd{make V=0 CFLAGS=-Wall}
+ CC main.o
+main.c: In function ‘main’:
+main.c:3:3: warning: implicit declaration of function ‘func’
+ CC func.o
+func.c: In function ‘func’:
+func.c:4:3: warning: ‘i’ used uninitialized in this function
+ CCLD foo
+@end example
+
+@cindex silent-rules and libtool
+Also, in projects using @command{libtool}, the use of silent rules can
+automatically enable the @command{libtool}'s @option{--silent} option:
+
+@example
+% @kbd{cat Makefile.am}
+lib_LTLIBRARIES = libx.la
+
+% @kbd{make # Both make and libtool are verbose by default.}
+...
+libtool: compile: gcc -DPACKAGE_NAME=\"foo\" ... -DLT_OBJDIR=\".libs/\"
+ -I. -g -O2 -MT libx.lo -MD -MP -MF .deps/libx.Tpo -c libx.c -fPIC
+ -DPIC -o .libs/libx.o
+mv -f .deps/libx.Tpo .deps/libx.Plo
+/bin/sh ./libtool --tag=CC --mode=link gcc -g -O2 -o libx.la -rpath
+ /usr/local/lib libx.lo
+libtool: link: gcc -shared .libs/libx.o -Wl,-soname -Wl,libx.so.0
+ -o .libs/libx.so.0.0.0
+libtool: link: cd .libs && rm -f libx.so && ln -s libx.so.0.0.0 libx.so
+...
+
+% @kbd{make V=0}
+ CC libx.lo
+ CCLD libx.la
+@end example
+
+Let's now see how the @option{silent-rules} mode interfaces with the
+package developer and the package user.
+
+To enable the use of @option{silent-rules} in his package, a developer
+needs to do either of the following:
+
+@itemize @bullet
+@item
+Add the @option{silent-rules} option as argument to @code{AM_INIT_AUTOMAKE}.
+@item
+Call the @code{AM_SILENT_RULES} macro from within the @file{configure.ac}
+file.
+@end itemize
+
+It is not possible to instead specify @option{silent-rules} in a
+@file{Makefile.am} file.
+
+If the developer has done either of the above, then the user of the
+package may influence the verbosity at @command{configure} run time as
+well as at @command{make} run time:
+
+@itemize @bullet
+@item
+@opindex --enable-silent-rules
+@opindex --disable-silent-rules
+Passing @option{--enable-silent-rules} to @command{configure} will cause
+build rules to be less verbose; the option @option{--disable-silent-rules}
+will cause normal verbose output.
+@item
+@vindex @code{V}
+At @command{make} run time, the default chosen at @command{configure}
+time may be overridden: @code{make V=1} will produce verbose output,
+@code{make V=0} less verbose output.
+@end itemize
+
+@cindex default verbosity for silent-rules
+Note that silent rules are @emph{disabled} by default; the user must
+enable them explicitly at either @command{configure} run time or at
+@command{make} run time. We think that this is a good policy, since
+it provides the casual user with enough information to prepare a good
+bug report in case anything breaks.
+
+Still, notwithstanding the rationales above, a developer who wants to
+make silent rules enabled by default in his own package can do so by
+adding a @samp{yes} argument to the @code{AM_SILENT_RULES} call in
+@file{configure.ac}. We advise against this approach, though.
+
+@c Keep in sync with silent-configsite.sh
+Users who prefer to have silent rules enabled by default can edit their
+@file{config.site} file to make the variable @code{enable_silent_rules}
+default to @samp{yes}. This should still allow disabling silent rules
+at @command{configure} time and at @command{make} time.
+
+@c FIXME: there's really a need to specify this explicitly?
+For portability to different @command{make} implementations, package authors
+are advised to not set the variable @code{V} inside the @file{Makefile.am}
+file, to allow the user to override the value for subdirectories as well.
+
+The current implementation of this feature normally uses nested
+variable expansion @samp{$(@var{var1}$(V))}, a @file{Makefile} feature
+that is not required by POSIX 2008 but is widely supported in
+practice. The @option{silent-rules} option thus turns off warnings
+about recursive variable expansion, which are in turn enabled by
+@option{-Wportability} (@pxref{automake Invocation}). On the rare
+@command{make} implementations that do not support nested variable
+expansion, whether rules are silent is always determined at configure
+time, and cannot be overridden at make time. Future versions of POSIX
+are likely to require nested variable expansion, so this minor
+limitation should go away with time.
+
+@vindex @code{AM_V_GEN}
+@vindex @code{AM_V_at}
+@vindex @code{AM_DEFAULT_VERBOSITY}
+@vindex @code{AM_V}
+@vindex @code{AM_DEFAULT_V}
+To extend the silent mode to your own rules, you have two choices:
+
+@itemize @bullet
+@item
+You can use the predefined variable @code{AM_V_GEN} as a prefix to
+commands that should output a status line in silent mode, and
+@code{AM_V_at} as a prefix to commands that should not output anything
+in silent mode. When output is to be verbose, both of these variables
+will expand to the empty string.
+@item
+You can add your own variables, so strings of your own choice are shown.
+The following snippet shows how you would define your own equivalent of
+@code{AM_V_GEN}:
+
+@example
+pkg_verbose = $(pkg_verbose_@@AM_V@@)
+pkg_verbose_ = $(pkg_verbose_@@AM_DEFAULT_V@@)
+pkg_verbose_0 = @@echo PKG-GEN $@@;
+
+foo: foo.in
+ $(pkg_verbose)cp $(srcdir)/foo.in $@@
+@end example
+
+@end itemize
+
+As a final note, observe that, even when silent rules are enabled,
+the @option{--no-print-directory} option is still required with GNU
+@command{make} if the ``@i{Entering/Leaving directory ...}'' messages
+are to be disabled.

+
+@emph{The features described in this section are deprecated; you must
+not use any of them in new code, and should remove their use from older
+but still maintained code: they will be withdrawn the next major Automake
+release (1.13).}
+
+Some packages, notably GNU GCC and GNU gdb, used to have a build
+environment originally written at Cygnus Support (subsequently renamed
+Cygnus Solutions, and then later purchased by Red Hat). Packages with
+this ancestry are sometimes referred to as ``Cygnus'' trees.
+
+A Cygnus tree has slightly different rules for how a
+@file{Makefile.in} is to be constructed. Passing @option{--cygnus} to
+@command{automake} will cause any generated @file{Makefile.in} to
+comply with Cygnus rules.
+
+Here are the precise effects of @option{--cygnus}:
+
+@itemize @bullet
+
+@item
+The @option{foreign} strictness is implied.
+
+@item
+The options @option{no-installinfo}, @option{no-dependencies} and
+@option{no-dist} are implied (@pxref{Options}).
+
+@item
+The macro @code{AM_MAINTAINER_MODE} is required.
+
+@item
+Info files are always created in the build directory, and not in the
+source directory. Packages that don't use the @option{cygnus} option
+can emulate this effect by using the @option{no-installinfo} option
+and listing the generated info files in the @code{CLEANFILES} variable.
+
+@item
+@file{texinfo.tex} is not required if a Texinfo source file is
+specified. The assumption is that the file will be supplied, but in a
+place that Automake cannot find -- it is an artifact of how Cygnus
+packages are typically bundled. This effect can be emulated in
+packages not using the @option{cygnus} option with a proper definition
+of the @code{TEXINFO_TEX} variable (@pxref{Texinfo}).
+
+@item
+Certain tools will be searched for in the build tree as well as in the
+user's @env{PATH}. These tools are @command{runtest}, @command{expect},

+
+With some minor exceptions (for example @code{_PROGRAMS} variables,

+@file{Makefile.in} verbatim.
+
+@cindex copying semantics
+
+These copying semantics mean that many problems can be worked around

+@cindex definitions, conflicts
+
+Since a @file{Makefile.in} is built from data gathered from three
+different places (@file{Makefile.am}, @file{configure.ac}, and
+@command{automake} itself), it is possible to have conflicting
+definitions of rules or variables. When building @file{Makefile.in}
+the following priorities are respected by @command{automake} to ensure
+the user always has the last word:
+
+@itemize
+@item
+User defined variables in @file{Makefile.am} have priority over
+variables @code{AC_SUBST}ed from @file{configure.ac}, and
+@code{AC_SUBST}ed variables have priority over
+@command{automake}-defined variables.
+@item
+As far as rules are concerned, a user-defined rule overrides any
+@command{automake}-defined rule for the same target.
+@end itemize
+
+@cindex overriding rules
+@cindex overriding semantics
+@cindex rules, overriding
+
+These overriding semantics make it possible to fine tune some default
+settings of Automake, or replace some of its rules. Overriding
+Automake rules is often inadvisable, particularly in the topmost
+directory of a package with subdirectories. The @option{-Woverride}
+option (@pxref{automake Invocation}) comes in handy to catch overridden
+definitions.
+
+Note that Automake does not make any distinction between rules with
+commands and rules that only specify dependencies. So it is not
+possible to append new dependencies to an @command{automake}-defined
+target without redefining the entire rule.
+
+@cindex @option{-local} targets
+@cindex local targets

+@code{installcheck} and the various @code{clean} targets
+(@code{mostlyclean}, @code{clean}, @code{distclean}, and
+@code{maintainer-clean}).
+
+Note that there are no @code{uninstall-exec-local} or
+@code{uninstall-data-local} targets; just use @code{uninstall-local}.
+It doesn't make sense to uninstall just data or just executables.
+
+For instance, here is one way to erase a subdirectory during
+@samp{make clean} (@pxref{Clean}).
+
+@example
+clean-local:
+ -rm -rf testSubDir
+@end example
+
+You may be tempted to use @code{install-data-local} to install a file
+to some hard-coded location, but you should avoid this
+(@pxref{Hard-Coded Install Paths}).
+
+With the @code{-local} targets, there is no particular guarantee of
+execution order; typically, they are run early, but with parallel
+make, there is no way to be sure of that.
+
+@cindex @option{-hook} targets
+@cindex hook targets
+@trindex install-data-hook
+@trindex install-exec-hook
+@trindex uninstall-hook
+@trindex dist-hook
+
+In contrast, some rules also have a way to run another rule, called a
+@dfn{hook}; hooks are always executed after the main rule's work is done.
+The hook is named after the principal target, with @samp{-hook} appended.
+The targets allowing hooks are @code{install-data},
+@code{install-exec}, @code{uninstall}, @code{dist}, and
+@code{distcheck}.
+
+For instance, here is how to create a hard link to an installed program:
+
+@example
+install-exec-hook:
+ ln $(DESTDIR)$(bindir)/program$(EXEEXT) \
+ $(DESTDIR)$(bindir)/proglink$(EXEEXT)
+@end example
+
+Although cheaper and more portable than symbolic links, hard links
+will not work everywhere (for instance, OS/2 does not have
+@command{ln}). Ideally you should fall back to @samp{cp -p} when
+@command{ln} does not work. An easy way, if symbolic links are
+acceptable to you, is to add @code{AC_PROG_LN_S} to
+@file{configure.ac} (@pxref{Particular Programs, , Particular Program
+Checks, autoconf, The Autoconf Manual}) and use @samp{$(LN_S)} in
+@file{Makefile.am}.
+
+@cindex versioned binaries, installing

+
+@c Keep in sync with insthook.sh
+@example
+install-exec-hook:
+ cd $(DESTDIR)$(bindir) && \
+ mv -f prog$(EXEEXT) prog-$(VERSION)$(EXEEXT) && \
+ $(LN_S) prog-$(VERSION)$(EXEEXT) prog$(EXEEXT)
+@end example
+
+Note that we rename the program so that a new version will erase the
+symbolic link, not the real binary. Also we @command{cd} into the
+destination directory in order to create relative links.
+
+When writing @code{install-exec-hook} or @code{install-data-hook},
+please bear in mind that the exec/data distinction is based on the
+installation directory, not on the primary used (@pxref{The Two Parts of
+Install}).
+@c Keep in sync with primary-prefix-couples-documented-valid.sh
+So a @code{foo_SCRIPTS} will be installed by
+@code{install-data}, and a @code{barexec_SCRIPTS} will be installed by
+@code{install-exec}. You should define your hooks consequently.

+@cindex Interfacing with third-party packages
+
+In most projects all @file{Makefile}s are generated by Automake. In

+a third-party project with its own build system, not using Automake.
+
+It is possible to list arbitrary directories in @code{SUBDIRS} or
+@code{DIST_SUBDIRS} provided each of these directories has a
+@file{Makefile} that recognizes all the following recursive targets.
+
+@cindex recursive targets and third-party @file{Makefile}s

+
+If you have ever used Gettext in a project, this is a good example of
+how third-party @file{Makefile}s can be used with Automake. The
+@file{Makefile}s @command{gettextize} puts in the @file{po/} and
+@file{intl/} directories are handwritten @file{Makefile}s that
+implement all these targets. That way they can be added to
+@code{SUBDIRS} in Automake packages.
+
+Directories that are only listed in @code{DIST_SUBDIRS} but not in
+@code{SUBDIRS} need only the @code{distclean},
+@code{maintainer-clean}, and @code{distdir} rules (@pxref{Conditional
+Subdirectories}).
+
+Usually, many of these rules are irrelevant to the third-party
+subproject, but they are required for the whole package to work. It's
+OK to have a rule that does nothing, so if you are integrating a
+third-party project with no documentation or tag support, you could
+simply augment its @file{Makefile} as follows:
+
+@example
+EMPTY_AUTOMAKE_TARGETS = dvi pdf ps info html tags ctags
+.PHONY: $(EMPTY_AUTOMAKE_TARGETS)
+$(EMPTY_AUTOMAKE_TARGETS):
+@end example
+
+Another aspect of integrating third-party build systems is whether
+they support VPATH builds (@pxref{VPATH Builds}). Obviously if the
+subpackage does not support VPATH builds the whole package will not
+support VPATH builds. This in turns means that @samp{make distcheck}
+will not work, because it relies on VPATH builds. Some people can
+live without this (actually, many Automake users have never heard of
+@samp{make distcheck}). Other people may prefer to revamp the
+existing @file{Makefile}s to support VPATH@. Doing so does not
+necessarily require Automake, only Autoconf is needed (@pxref{Build
+Directories, , Build Directories, autoconf, The Autoconf Manual}).
+The necessary substitutions: @samp{@@srcdir@@}, @samp{@@top_srcdir@@},
+and @samp{@@top_builddir@@} are defined by @file{configure} when it
+processes a @file{Makefile} (@pxref{Preset Output Variables, , Preset
+Output Variables, autoconf, The Autoconf Manual}), they are not
+computed by the Makefile like the aforementioned @samp{$(distdir)} and
+@samp{$(top_distdir)} variables.
+
+It is sometimes inconvenient to modify a third-party @file{Makefile}
+to introduce the above required targets. For instance, one may want to
+keep the third-party sources untouched to ease upgrades to new
+versions.
+
+@cindex @file{GNUmakefile} including @file{Makefile}
+Here are two other ideas. If GNU make is assumed, one possibility is
+to add to that subdirectory a @file{GNUmakefile} that defines the
+required targets and includes the third-party @file{Makefile}. For
+this to work in VPATH builds, @file{GNUmakefile} must lie in the build
+directory; the easiest way to do this is to write a
+@file{GNUmakefile.in} instead, and have it processed with
+@code{AC_CONFIG_FILES} from the outer package. For example if we
+assume @file{Makefile} defines all targets except the documentation
+targets, and that the @code{check} target is actually called
+@code{test}, we could write @file{GNUmakefile} (or
+@file{GNUmakefile.in}) like this:
+
+@example
+# First, include the real Makefile
+include Makefile
+# Then, define the other targets needed by Automake Makefiles.
+.PHONY: dvi pdf ps info html check
+dvi pdf ps info html:
+check: test
+@end example
+
+@cindex Proxy @file{Makefile} for third-party packages
+A similar idea that does not use @code{include} is to write a proxy
+@file{Makefile} that dispatches rules to the real @file{Makefile},
+either with @samp{$(MAKE) -f Makefile.real $(AM_MAKEFLAGS) target} (if
+it's OK to rename the original @file{Makefile}) or with @samp{cd
+subdir && $(MAKE) $(AM_MAKEFLAGS) target} (if it's OK to store the
+subdirectory project one directory deeper). The good news is that
+this proxy @file{Makefile} can be generated with Automake. All we
+need are @option{-local} targets (@pxref{Extending}) that perform the
+dispatch. Of course the other Automake features are available, so you
+could decide to let Automake perform distribution or installation.
+Here is a possible @file{Makefile.am}:
+
+@example
+all-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) all
+check-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) test
+clean-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) clean
+
+# Assuming the package knows how to install itself
+install-data-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) install-data
+install-exec-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) install-exec
+uninstall-local:
+ cd subdir && $(MAKE) $(AM_MAKEFLAGS) uninstall
+
+# Distribute files from here.
+EXTRA_DIST = subdir/Makefile subdir/program.c ...
+@end example
+
+Pushing this idea to the extreme, it is also possible to ignore the
+subproject build system and build everything from this proxy
+@file{Makefile.am}. This might sound very sensible if you need VPATH
+builds but the subproject does not support them.
+
+@node Distributing
+@chapter Distributing @file{Makefile.in}s
+
+Automake places no restrictions on the distribution of the resulting
+@file{Makefile.in}s. We still encourage software authors to
+distribute their work under terms like those of the GPL, but doing so
+is not required to use Automake.
+
+Some of the files that can be automatically installed via the
+@option{--add-missing} switch do fall under the GPL@. However, these also
+have a special exception allowing you to distribute them with your
+package, regardless of the licensing you choose.
+
+
+@node API Versioning
+@chapter Automake API Versioning
+
+New Automake releases usually include bug fixes and new features.
+Unfortunately they may also introduce new bugs and incompatibilities.
+This makes four reasons why a package may require a particular Automake
+version.
+
+Things get worse when maintaining a large tree of packages, each one
+requiring a different version of Automake. In the past, this meant that
+any developer (and sometimes users) had to install several versions of
+Automake in different places, and switch @samp{$PATH} appropriately for
+each package.
+
+Starting with version 1.6, Automake installs versioned binaries. This
+means you can install several versions of Automake in the same
+@samp{$prefix}, and can select an arbitrary Automake version by running
+@command{automake-1.6} or @command{automake-1.7} without juggling with
+@samp{$PATH}. Furthermore, @file{Makefile}'s generated by Automake 1.6
+will use @command{automake-1.6} explicitly in their rebuild rules.
+
+The number @samp{1.6} in @command{automake-1.6} is Automake's API version,
+not Automake's version. If a bug fix release is made, for instance
+Automake 1.6.1, the API version will remain 1.6. This means that a
+package that works with Automake 1.6 should also work with 1.6.1; after
+all, this is what people expect from bug fix releases.
+
+If your package relies on a feature or a bug fix introduced in
+a release, you can pass this version as an option to Automake to ensure
+older releases will not be used. For instance, use this in your
+@file{configure.ac}:
+
+@example
+ AM_INIT_AUTOMAKE([1.6.1]) dnl Require Automake 1.6.1 or better.
+@end example
+
+@noindent
+or, in a particular @file{Makefile.am}:
+
+@example
+ AUTOMAKE_OPTIONS = 1.6.1 # Require Automake 1.6.1 or better.
+@end example
+
+@noindent
+Automake will print an error message if its version is
+older than the requested version.
+
+
+@heading What is in the API
+
+Automake's programming interface is not easy to define. Basically it
+should include at least all @strong{documented} variables and targets
+that a @file{Makefile.am} author can use, any behavior associated with
+them (e.g., the places where @samp{-hook}'s are run), the command line
+interface of @command{automake} and @command{aclocal}, @dots{}
+
+@heading What is not in the API
+
+Every undocumented variable, target, or command line option, is not part
+of the API@. You should avoid using them, as they could change from one
+version to the other (even in bug fix releases, if this helps to fix a
+bug).
+
+If it turns out you need to use such an undocumented feature, contact
+@email{automake@@gnu.org} and try to get it documented and exercised by
+the test-suite.
+
+@node Upgrading
+@chapter Upgrading a Package to a Newer Automake Version
+
+Automake maintains three kind of files in a package.
+
+@itemize
+@item @file{aclocal.m4}
+@item @file{Makefile.in}s
+@item auxiliary tools like @file{install-sh} or @file{py-compile}
+@end itemize
+
+@file{aclocal.m4} is generated by @command{aclocal} and contains some
+Automake-supplied M4 macros. Auxiliary tools are installed by
+@samp{automake --add-missing} when needed. @file{Makefile.in}s are
+built from @file{Makefile.am} by @command{automake}, and rely on the
+definitions of the M4 macros put in @file{aclocal.m4} as well as the
+behavior of the auxiliary tools installed.
+
+Because all these files are closely related, it is important to
+regenerate all of them when upgrading to a newer Automake release.
+The usual way to do that is
+
+@example
+aclocal # with any option needed (such a -I m4)
+autoconf
+automake --add-missing --force-missing
+@end example
+
+@noindent
+or more conveniently:
+
+@example
+autoreconf -vfi
+@end example
+
+The use of @option{--force-missing} ensures that auxiliary tools will be
+overridden by new versions (@pxref{automake Invocation}).
+
+It is important to regenerate all these files each time Automake is
+upgraded, even between bug fixes releases. For instance, it is not
+unusual for a bug fix to involve changes to both the rules generated
+in @file{Makefile.in} and the supporting M4 macros copied to
+@file{aclocal.m4}.
+
+Presently @command{automake} is able to diagnose situations where
+@file{aclocal.m4} has been generated with another version of
+@command{aclocal}. However it never checks whether auxiliary scripts
+are up-to-date. In other words, @command{automake} will tell you when
+@command{aclocal} needs to be rerun, but it will never diagnose a
+missing @option{--force-missing}.
+
+Before upgrading to a new major release, it is a good idea to read the
+file @file{NEWS}. This file lists all changes between releases: new
+features, obsolete constructs, known incompatibilities, and
+workarounds.

+@node CVS
+@section CVS and generated files
+
+@subheading Background: distributed generated Files
+@cindex generated files, distributed
+@cindex rebuild rules
+
+Packages made with Autoconf and Automake ship with some generated
+files like @file{configure} or @file{Makefile.in}. These files were
+generated on the developer's host and are distributed so that
+end-users do not have to install the maintainer tools required to
+rebuild them. Other generated files like Lex scanners, Yacc parsers,
+or Info documentation, are usually distributed on similar grounds.
+
+Automake outputs rules in @file{Makefile}s to rebuild these files. For
+instance, @command{make} will run @command{autoconf} to rebuild
+@file{configure} whenever @file{configure.ac} is changed. This makes
+development safer by ensuring a @file{configure} is never out-of-date
+with respect to @file{configure.ac}.
+
+As generated files shipped in packages are up-to-date, and because
+@command{tar} preserves times-tamps, these rebuild rules are not
+triggered when a user unpacks and builds a package.
+
+@subheading Background: CVS and Timestamps
+@cindex timestamps and CVS
+@cindex CVS and timestamps
+
+Unless you use CVS keywords (in which case files must be updated at
+commit time), CVS preserves timestamp during @samp{cvs commit} and
+@samp{cvs import -d} operations.
+
+When you check out a file using @samp{cvs checkout} its timestamp is
+set to that of the revision that is being checked out.
+
+However, during @command{cvs update}, files will have the date of the
+update, not the original timestamp of this revision. This is meant to
+make sure that @command{make} notices sources files have been updated.
+
+This timestamp shift is troublesome when both sources and generated
+files are kept under CVS@. Because CVS processes files in lexical
+order, @file{configure.ac} will appear newer than @file{configure}
+after a @command{cvs update} that updates both files, even if
+@file{configure} was newer than @file{configure.ac} when it was
+checked in. Calling @command{make} will then trigger a spurious rebuild
+of @file{configure}.
+
+@subheading Living with CVS in Autoconfiscated Projects
+@cindex CVS and generated files
+@cindex generated files and CVS
+
+There are basically two clans amongst maintainers: those who keep all
+distributed files under CVS, including generated files, and those who
+keep generated files @emph{out} of CVS.
+
+@subsubheading All Files in CVS
+
+@itemize @bullet
+@item
+The CVS repository contains all distributed files so you know exactly
+what is distributed, and you can checkout any prior version entirely.
+
+@item
+Maintainers can see how generated files evolve (for instance, you can
+see what happens to your @file{Makefile.in}s when you upgrade Automake
+and make sure they look OK).
+
+@item
+Users do not need the autotools to build a checkout of the project, it
+works just like a released tarball.
+
+@item
+If users use @command{cvs update} to update their copy, instead of
+@command{cvs checkout} to fetch a fresh one, timestamps will be
+inaccurate. Some rebuild rules will be triggered and attempt to
+run developer tools such as @command{autoconf} or @command{automake}.
+
+Actually, calls to such tools are all wrapped into a call to the
+@command{missing} script discussed later (@pxref{maintainer-mode}).
+@command{missing} will take care of fixing the timestamps when these
+tools are not installed, so that the build can continue.
+
+@item
+In distributed development, developers are likely to have different
+version of the maintainer tools installed. In this case rebuilds
+triggered by timestamp lossage will lead to spurious changes
+to generated files. There are several solutions to this:
+
+@itemize
+@item
+All developers should use the same versions, so that the rebuilt files
+are identical to files in CVS@. (This starts to be difficult when each
+project you work on uses different versions.)
+@item
+Or people use a script to fix the timestamp after a checkout (the GCC
+folks have such a script).
+@item
+Or @file{configure.ac} uses @code{AM_MAINTAINER_MODE}, which will
+disable all these rebuild rules by default. This is further discussed
+in @ref{maintainer-mode}.
+@end itemize
+
+@item
+Although we focused on spurious rebuilds, the converse can also
+happen. CVS's timestamp handling can also let you think an
+out-of-date file is up-to-date.
+
+For instance, suppose a developer has modified @file{Makefile.am} and
+has rebuilt @file{Makefile.in}, and then decides to do a last-minute
+change to @file{Makefile.am} right before checking in both files
+(without rebuilding @file{Makefile.in} to account for the change).
+
+This last change to @file{Makefile.am} makes the copy of
+@file{Makefile.in} out-of-date. Since CVS processes files
+alphabetically, when another developer @samp{cvs update}s his or her
+tree, @file{Makefile.in} will happen to be newer than
+@file{Makefile.am}. This other developer will not see that
+@file{Makefile.in} is out-of-date.
+
+@end itemize
+
+@subsubheading Generated Files out of CVS
+
+One way to get CVS and @command{make} working peacefully is to never
+store generated files in CVS, i.e., do not CVS-control files that
+are @file{Makefile} targets (also called @emph{derived} files).
+
+This way developers are not annoyed by changes to generated files. It
+does not matter if they all have different versions (assuming they are
+compatible, of course). And finally, timestamps are not lost, changes
+to sources files can't be missed as in the
+@file{Makefile.am}/@file{Makefile.in} example discussed earlier.
+
+The drawback is that the CVS repository is not an exact copy of what
+is distributed and that users now need to install various development
+tools (maybe even specific versions) before they can build a checkout.
+But, after all, CVS's job is versioning, not distribution.
+
+Allowing developers to use different versions of their tools can also
+hide bugs during distributed development. Indeed, developers will be
+using (hence testing) their own generated files, instead of the
+generated files that will be released actually. The developer who
+prepares the tarball might be using a version of the tool that
+produces bogus output (for instance a non-portable C file), something
+other developers could have noticed if they weren't using their own
+versions of this tool.
+
+@subheading Third-party Files
+@cindex CVS and third-party files
+@cindex third-party files and CVS
+
+Another class of files not discussed here (because they do not cause
+timestamp issues) are files that are shipped with a package, but
+maintained elsewhere. For instance, tools like @command{gettextize}
+and @command{autopoint} (from Gettext) or @command{libtoolize} (from
+Libtool), will install or update files in your package.
+
+These files, whether they are kept under CVS or not, raise similar
+concerns about version mismatch between developers' tools. The
+Gettext manual has a section about this, see @ref{CVS Issues, CVS
+Issues, Integrating with CVS, gettext, GNU gettext tools}.
+
+@node maintainer-mode
+@section @command{missing} and @code{AM_MAINTAINER_MODE}
+
+@subheading @command{missing}
+@cindex @command{missing}, purpose
+
+The @command{missing} script is a wrapper around several maintainer
+tools, designed to warn users if a maintainer tool is required but
+missing. Typical maintainer tools are @command{autoconf},
+@command{automake}, @command{bison}, etc. Because file generated by
+these tools are shipped with the other sources of a package, these
+tools shouldn't be required during a user build and they are not
+checked for in @file{configure}.
+
+However, if for some reason a rebuild rule is triggered and involves a
+missing tool, @command{missing} will notice it and warn the user.
+Besides the warning, when a tool is missing, @command{missing} will
+attempt to fix timestamps in a way that allows the build to continue.
+For instance, @command{missing} will touch @file{configure} if
+@command{autoconf} is not installed. When all distributed files are
+kept under version control, this feature of @command{missing} allows a
+user @emph{with no maintainer tools} to build a package off its version
+control repository, bypassing any timestamp inconsistency (implied by
+e.g.@: @samp{cvs update} or @samp{git clone}).
+
+If the required tool is installed, @command{missing} will run it and
+won't attempt to continue after failures. This is correct during
+development: developers love fixing failures. However, users with
+wrong versions of maintainer tools may get an error when the rebuild
+rule is spuriously triggered, halting the build. This failure to let
+the build continue is one of the arguments of the
+@code{AM_MAINTAINER_MODE} advocates.
+
+@subheading @code{AM_MAINTAINER_MODE}
+@cindex @code{AM_MAINTAINER_MODE}, purpose
+@acindex AM_MAINTAINER_MODE
+
+@code{AM_MAINTAINER_MODE} allows you to choose whether the so called
+"rebuild rules" should be enabled or disabled. With
+@code{AM_MAINTAINER_MODE([enable])}, they are enabled by default,
+otherwise they are disabled by default. In the latter case, if
+you have @code{AM_MAINTAINER_MODE} in @file{configure.ac}, and run
+@samp{./configure && make}, then @command{make} will *never* attempt to
+rebuild @file{configure}, @file{Makefile.in}s, Lex or Yacc outputs, etc.
+I.e., this disables build rules for files that are usually distributed
+and that users should normally not have to update.
+
+The user can override the default setting by passing either
+@samp{--enable-maintainer-mode} or @samp{--disable-maintainer-mode}
+to @command{configure}.
+
+People use @code{AM_MAINTAINER_MODE} either because they do not want their
+users (or themselves) annoyed by timestamps lossage (@pxref{CVS}), or
+because they simply can't stand the rebuild rules and prefer running
+maintainer tools explicitly.
+
+@code{AM_MAINTAINER_MODE} also allows you to disable some custom build
+rules conditionally. Some developers use this feature to disable
+rules that need exotic tools that users may not have available.
+
+Several years ago Fran@,{c}ois Pinard pointed out several arguments
+against this @code{AM_MAINTAINER_MODE} macro. Most of them relate to
+insecurity. By removing dependencies you get non-dependable builds:
+changes to sources files can have no effect on generated files and this
+can be very confusing when unnoticed. He adds that security shouldn't
+be reserved to maintainers (what @option{--enable-maintainer-mode}
+suggests), on the contrary. If one user has to modify a
+@file{Makefile.am}, then either @file{Makefile.in} should be updated
+or a warning should be output (this is what Automake uses
+@command{missing} for) but the last thing you want is that nothing
+happens and the user doesn't notice it (this is what happens when
+rebuild rules are disabled by @code{AM_MAINTAINER_MODE}).
+
+Jim Meyering, the inventor of the @code{AM_MAINTAINER_MODE} macro was
+swayed by Fran@,{c}ois's arguments, and got rid of
+@code{AM_MAINTAINER_MODE} in all of his packages.
+
+Still many people continue to use @code{AM_MAINTAINER_MODE}, because
+it helps them working on projects where all files are kept under version
+control, and because @command{missing} isn't enough if you have the
+wrong version of the tools.
+
+
+@node Wildcards
+@section Why doesn't Automake support wildcards?
+@cindex wildcards
+
+Developers are lazy. They would often like to use wildcards in
+@file{Makefile.am}s, so that they would not need to remember to
+update @file{Makefile.am}s every time they add, delete, or rename
+a file.
+
+There are several objections to this:
+@itemize
+@item
+When using CVS (or similar) developers need to remember they have to
+run @samp{cvs add} or @samp{cvs rm} anyway. Updating
+@file{Makefile.am} accordingly quickly becomes a reflex.
+
+Conversely, if your application doesn't compile
+because you forgot to add a file in @file{Makefile.am}, it will help
+you remember to @samp{cvs add} it.
+
+@item
+Using wildcards makes it easy to distribute files by mistake. For
+instance, some code a developer is experimenting with (a test case,
+say) that should not be part of the distribution.
+
+@item
+Using wildcards it's easy to omit some files by mistake. For
+instance, one developer creates a new file, uses it in many places,
+but forgets to commit it. Another developer then checks out the
+incomplete project and is able to run @samp{make dist} successfully,
+even though a file is missing. By listing files, @samp{make dist}
+@emph{will} complain.
+
+@item
+Wildcards are not portable to some non-GNU @command{make} implementations,
+e.g., NetBSD @command{make} will not expand globs such as @samp{*} in
+prerequisites of a target.
+
+@item
+Finally, it's really hard to @emph{forget} to add a file to
+@file{Makefile.am}: files that are not listed in @file{Makefile.am} are
+not compiled or installed, so you can't even test them.
+@end itemize
+
+Still, these are philosophical objections, and as such you may disagree,
+or find enough value in wildcards to dismiss all of them. Before you
+start writing a patch against Automake to teach it about wildcards,
+let's see the main technical issue: portability.
+
+Although @samp{$(wildcard ...)} works with GNU @command{make}, it is
+not portable to other @command{make} implementations.
+
+The only way Automake could support @command{$(wildcard ...)} is by
+expending @command{$(wildcard ...)} when @command{automake} is run.
+The resulting @file{Makefile.in}s would be portable since they would
+list all files and not use @samp{$(wildcard ...)}. However that
+means developers would need to remember to run @command{automake} each
+time they add, delete, or rename files.
+
+Compared to editing @file{Makefile.am}, this is a very small gain. Sure,
+it's easier and faster to type @samp{automake; make} than to type
+@samp{emacs Makefile.am; make}. But nobody bothered enough to write a
+patch to add support for this syntax. Some people use scripts to
+generate file lists in @file{Makefile.am} or in separate
+@file{Makefile} fragments.
+
+Even if you don't care about portability, and are tempted to use
+@samp{$(wildcard ...)} anyway because you target only GNU Make, you
+should know there are many places where Automake needs to know exactly
+which files should be processed. As Automake doesn't know how to
+expand @samp{$(wildcard ...)}, you cannot use it in these places.
+@samp{$(wildcard ...)} is a black box comparable to @code{AC_SUBST}ed
+variables as far Automake is concerned.
+
+You can get warnings about @samp{$(wildcard ...}) constructs using the
+@option{-Wportability} flag.
+
+@node Limitations on File Names
+@section Limitations on File Names
+@cindex file names, limitations on
+
+Automake attempts to support all kinds of file names, even those that
+contain unusual characters or are unusually long. However, some
+limitations are imposed by the underlying operating system and tools.
+
+Most operating systems prohibit the use of the null byte in file
+names, and reserve @samp{/} as a directory separator. Also, they
+require that file names are properly encoded for the user's locale.
+Automake is subject to these limits.
+
+Portable packages should limit themselves to POSIX file
+names. These can contain ASCII letters and digits,
+@samp{_}, @samp{.}, and @samp{-}. File names consist of components
+separated by @samp{/}. File name components cannot begin with
+@samp{-}.
+
+Portable POSIX file names cannot contain components that exceed a
+14-byte limit, but nowadays it's normally safe to assume the
+more-generous XOPEN limit of 255 bytes. POSIX
+limits file names to 255 bytes (XOPEN allows 1023 bytes),
+but you may want to limit a source tarball to file names of 99 bytes
+to avoid interoperability problems with old versions of @command{tar}.
+
+If you depart from these rules (e.g., by using non-ASCII
+characters in file names, or by using lengthy file names), your
+installers may have problems for reasons unrelated to Automake.
+However, if this does not concern you, you should know about the
+limitations imposed by Automake itself. These limitations are
+undesirable, but some of them seem to be inherent to underlying tools
+like Autoconf, Make, M4, and the shell. They fall into three
+categories: install directories, build directories, and file names.
+
+The following characters:
+
+@example
+@r{newline} " # $ ' `
+@end example
+
+should not appear in the names of install directories. For example,
+the operand of @command{configure}'s @option{--prefix} option should
+not contain these characters.
+
+Build directories suffer the same limitations as install directories,
+and in addition should not contain the following characters:
+
+@example
+& @@ \
+@end example
+
+For example, the full name of the directory containing the source
+files should not contain these characters.
+
+Source and installation file names like @file{main.c} are limited even
+further: they should conform to the POSIX/XOPEN
+rules described above. In addition, if you plan to port to
+non-POSIX environments, you should avoid file names that
+differ only in case (e.g., @file{makefile} and @file{Makefile}).
+Nowadays it is no longer worth worrying about the 8.3 limits of
+DOS file systems.

+@samp{make distcheck} will perform a @code{VPATH} build of your
+package (@pxref{VPATH Builds}), and then call @samp{make distclean}.
+Files left in the build directory after @samp{make distclean} has run
+are listed after this error.
+
+This diagnostic really covers two kinds of errors:
+
+@itemize @bullet
+@item
+files that are forgotten by distclean;
+@item
+distributed files that are erroneously rebuilt.
+@end itemize
+
+The former left-over files are not distributed, so the fix is to mark
+them for cleaning (@pxref{Clean}), this is obvious and doesn't deserve
+more explanations.
+
+The latter bug is not always easy to understand and fix, so let's
+proceed with an example. Suppose our package contains a program for
+which we want to build a man page using @command{help2man}. GNU
+@command{help2man} produces simple manual pages from the @option{--help}
+and @option{--version} output of other commands (@pxref{Top, , Overview,
+help2man, The Help2man Manual}). Because we don't want to force our
+users to install @command{help2man}, we decide to distribute the
+generated man page using the following setup.
+
+@example
+# This Makefile.am is bogus.
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c
+dist_man_MANS = foo.1
+
+foo.1: foo$(EXEEXT)
+ help2man --output=foo.1 ./foo$(EXEEXT)
+@end example
+
+This will effectively distribute the man page. However,
+@samp{make distcheck} will fail with:
+
+@example
+ERROR: files left in build directory after distclean:
+./foo.1
+@end example
+
+Why was @file{foo.1} rebuilt? Because although distributed,
+@file{foo.1} depends on a non-distributed built file:
+@file{foo$(EXEEXT)}. @file{foo$(EXEEXT)} is built by the user, so it
+will always appear to be newer than the distributed @file{foo.1}.
+
+@samp{make distcheck} caught an inconsistency in our package. Our
+intent was to distribute @file{foo.1} so users do not need to install
+@command{help2man}, however since this rule causes this file to be
+always rebuilt, users @emph{do} need @command{help2man}. Either we
+should ensure that @file{foo.1} is not rebuilt by users, or there is
+no point in distributing @file{foo.1}.
+
+More generally, the rule is that distributed files should never depend
+on non-distributed built files. If you distribute something
+generated, distribute its sources.
+
+One way to fix the above example, while still distributing
+@file{foo.1} is to not depend on @file{foo$(EXEEXT)}. For instance,
+assuming @command{foo --version} and @command{foo --help} do not
+change unless @file{foo.c} or @file{configure.ac} change, we could
+write the following @file{Makefile.am}:
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c
+dist_man_MANS = foo.1
+
+foo.1: foo.c $(top_srcdir)/configure.ac
+ $(MAKE) $(AM_MAKEFLAGS) foo$(EXEEXT)
+ help2man --output=foo.1 ./foo$(EXEEXT)
+@end example
+
+This way, @file{foo.1} will not get rebuilt every time
+@file{foo$(EXEEXT)} changes. The @command{make} call makes sure
+@file{foo$(EXEEXT)} is up-to-date before @command{help2man}. Another
+way to ensure this would be to use separate directories for binaries
+and man pages, and set @code{SUBDIRS} so that binaries are built
+before man pages.
+
+We could also decide not to distribute @file{foo.1}. In
+this case it's fine to have @file{foo.1} dependent upon
+@file{foo$(EXEEXT)}, since both will have to be rebuilt.
+However it would be impossible to build the package in a
+cross-compilation, because building @file{foo.1} involves
+an @emph{execution} of @file{foo$(EXEEXT)}.
+
+Another context where such errors are common is when distributed files
+are built by tools that are built by the package. The pattern is
+similar:
+
+@example
+distributed-file: built-tools distributed-sources
+ build-command
+@end example
+
+@noindent
+should be changed to
+
+@example
+distributed-file: distributed-sources
+ $(MAKE) $(AM_MAKEFLAGS) built-tools
+ build-command
+@end example
+
+@noindent
+or you could choose not to distribute @file{distributed-file}, if
+cross-compilation does not matter.
+
+The points made through these examples are worth a summary:
+
+@cartouche
+@itemize
+@item
+Distributed files should never depend upon non-distributed built
+files.
+@item
+Distributed files should be distributed with all their dependencies.
+@item
+If a file is @emph{intended} to be rebuilt by users, then there is no point
+in distributing it.
+@end itemize
+@end cartouche
+
+@vrindex distcleancheck_listfiles
+For desperate cases, it's always possible to disable this check by
+setting @code{distcleancheck_listfiles} as documented in @ref{Checking
+the Distribution}.
+Make sure you do understand the reason why @samp{make distcheck}
+complains before you do this. @code{distcleancheck_listfiles} is a
+way to @emph{hide} errors, not to fix them. You can always do better.

+@cindex @code{UPCFLAGS} and @code{AM_UPCFLAGS}
+@cindex @code{YFLAGS} and @code{AM_YFLAGS}
+
+This section attempts to answer all the above questions. We will
+mostly discuss @code{CPPFLAGS} in our examples, but actually the
+answer holds for all the compile flags used in Automake:
+@code{CCASFLAGS}, @code{CFLAGS}, @code{CPPFLAGS}, @code{CXXFLAGS},
+@code{FCFLAGS}, @code{FFLAGS}, @code{GCJFLAGS}, @code{LDFLAGS},
+@code{LFLAGS}, @code{LIBTOOLFLAGS}, @code{OBJCFLAGS}, @code{OBJCXXFLAGS},
+@code{RFLAGS}, @code{UPCFLAGS}, and @code{YFLAGS}.
+
+@code{CPPFLAGS}, @code{AM_CPPFLAGS}, and @code{mumble_CPPFLAGS} are
+three variables that can be used to pass flags to the C preprocessor
+(actually these variables are also used for other languages like C++
+or preprocessed Fortran). @code{CPPFLAGS} is the user variable
+(@pxref{User Variables}), @code{AM_CPPFLAGS} is the Automake variable,
+and @code{mumble_CPPFLAGS} is the variable specific to the
+@code{mumble} target (we call this a per-target variable,
+@pxref{Program and Library Variables}).
+
+Automake always uses two of these variables when compiling C sources
+files. When compiling an object file for the @code{mumble} target,
+the first variable will be @code{mumble_CPPFLAGS} if it is defined, or
+@code{AM_CPPFLAGS} otherwise. The second variable is always
+@code{CPPFLAGS}.
+
+In the following example,
+
+@example
+bin_PROGRAMS = foo bar
+foo_SOURCES = xyz.c
+bar_SOURCES = main.c
+foo_CPPFLAGS = -DFOO
+AM_CPPFLAGS = -DBAZ
+@end example
+
+@noindent
+@file{xyz.o} will be compiled with @samp{$(foo_CPPFLAGS) $(CPPFLAGS)},
+(because @file{xyz.o} is part of the @code{foo} target), while
+@file{main.o} will be compiled with @samp{$(AM_CPPFLAGS) $(CPPFLAGS)}
+(because there is no per-target variable for target @code{bar}).
+
+The difference between @code{mumble_CPPFLAGS} and @code{AM_CPPFLAGS}
+being clear enough, let's focus on @code{CPPFLAGS}. @code{CPPFLAGS}
+is a user variable, i.e., a variable that users are entitled to modify
+in order to compile the package. This variable, like many others,
+is documented at the end of the output of @samp{configure --help}.
+
+For instance, someone who needs to add @file{/home/my/usr/include} to
+the C compiler's search path would configure a package with
+
+@example
+./configure CPPFLAGS='-I /home/my/usr/include'
+@end example
+
+@noindent
+and this flag would be propagated to the compile rules of all
+@file{Makefile}s.
+
+It is also not uncommon to override a user variable at
+@command{make}-time. Many installers do this with @code{prefix}, but
+this can be useful with compiler flags too. For instance, if, while
+debugging a C++ project, you need to disable optimization in one
+specific object file, you can run something like
+
+@example
+rm file.o
+make CXXFLAGS=-O0 file.o
+make
+@end example
+
+The reason @samp{$(CPPFLAGS)} appears after @samp{$(AM_CPPFLAGS)} or
+@samp{$(mumble_CPPFLAGS)} in the compile command is that users
+should always have the last say. It probably makes more sense if you
+think about it while looking at the @samp{CXXFLAGS=-O0} above, which
+should supersede any other switch from @code{AM_CXXFLAGS} or
+@code{mumble_CXXFLAGS} (and this of course replaces the previous value
+of @code{CXXFLAGS}).
+
+You should never redefine a user variable such as @code{CPPFLAGS} in
+@file{Makefile.am}. Use @samp{automake -Woverride} to diagnose such
+mistakes. Even something like
+
+@example
+CPPFLAGS = -DDATADIR=\"$(datadir)\" @@CPPFLAGS@@
+@end example
+
+@noindent
+is erroneous. Although this preserves @file{configure}'s value of
+@code{CPPFLAGS}, the definition of @code{DATADIR} will disappear if a
+user attempts to override @code{CPPFLAGS} from the @command{make}
+command line.
+
+@example
+AM_CPPFLAGS = -DDATADIR=\"$(datadir)\"
+@end example
+
+@noindent
+is all that is needed here if no per-target flags are used.
+
+You should not add options to these user variables within
+@file{configure} either, for the same reason. Occasionally you need
+to modify these variables to perform a test, but you should reset
+their values afterwards. In contrast, it is OK to modify the
+@samp{AM_} variables within @file{configure} if you @code{AC_SUBST}
+them, but it is rather rare that you need to do this, unless you
+really want to change the default definitions of the @samp{AM_}
+variables in all @file{Makefile}s.
+
+What we recommend is that you define extra flags in separate
+variables. For instance, you may write an Autoconf macro that computes
+a set of warning options for the C compiler, and @code{AC_SUBST} them
+in @code{WARNINGCFLAGS}; you may also have an Autoconf macro that
+determines which compiler and which linker flags should be used to
+link with library @file{libfoo}, and @code{AC_SUBST} these in
+@code{LIBFOOCFLAGS} and @code{LIBFOOLDFLAGS}. Then, a
+@file{Makefile.am} could use these variables as follows:
+
+@example
+AM_CFLAGS = $(WARNINGCFLAGS)
+bin_PROGRAMS = prog1 prog2
+prog1_SOURCES = @dots{}
+prog2_SOURCES = @dots{}
+prog2_CFLAGS = $(LIBFOOCFLAGS) $(AM_CFLAGS)
+prog2_LDFLAGS = $(LIBFOOLDFLAGS)
+@end example
+
+In this example both programs will be compiled with the flags
+substituted into @samp{$(WARNINGCFLAGS)}, and @code{prog2} will
+additionally be compiled with the flags required to link with
+@file{libfoo}.
+
+Note that listing @code{AM_CFLAGS} in a per-target @code{CFLAGS}
+variable is a common idiom to ensure that @code{AM_CFLAGS} applies to
+every target in a @file{Makefile.in}.
+
+Using variables like this gives you full control over the ordering of
+the flags. For instance, if there is a flag in $(WARNINGCFLAGS) that
+you want to negate for a particular target, you can use something like
+@samp{prog1_CFLAGS = $(AM_CFLAGS) -no-flag}. If all these flags had
+been forcefully appended to @code{CFLAGS}, there would be no way to
+disable one flag. Yet another reason to leave user variables to
+users.
+
+Finally, we have avoided naming the variable of the example
+@code{LIBFOO_LDFLAGS} (with an underscore) because that would cause
+Automake to think that this is actually a per-target variable (like
+@code{mumble_LDFLAGS}) for some non-declared @code{LIBFOO} target.
+
+@subheading Other Variables
+
+There are other variables in Automake that follow similar principles
+to allow user options. For instance, Texinfo rules (@pxref{Texinfo})
+use @code{MAKEINFOFLAGS} and @code{AM_MAKEINFOFLAGS}. Similarly,
+DejaGnu tests (@pxref{DejaGnu Tests}) use @code{RUNTESTDEFAULTFLAGS} and
+@code{AM_RUNTESTDEFAULTFLAGS}. The tags and ctags rules
+(@pxref{Tags}) use @code{ETAGSFLAGS}, @code{AM_ETAGSFLAGS},
+@code{CTAGSFLAGS}, and @code{AM_CTAGSFLAGS}. Java rules
+(@pxref{Java}) use @code{JAVACFLAGS} and @code{AM_JAVACFLAGS}. None
+of these rules support per-target flags (yet).
+
+To some extent, even @code{AM_MAKEFLAGS} (@pxref{Subdirectories})
+obeys this naming scheme. The slight difference is that
+@code{MAKEFLAGS} is passed to sub-@command{make}s implicitly by
+@command{make} itself.
+
+However you should not think that all variables ending with
+@code{FLAGS} follow this convention. For instance,
+@code{DISTCHECK_CONFIGURE_FLAGS} (@pxref{Checking the Distribution}) and
+@code{ACLOCAL_AMFLAGS} (see @ref{Rebuilding} and @ref{Local Macros}),
+are two variables that are only useful to the maintainer and have no
+user counterpart.
+
+@code{ARFLAGS} (@pxref{A Library}) is usually defined by Automake and
+has neither @code{AM_} nor per-target cousin.
+
+Finally you should not think that the existence of a per-target
+variable implies the existence of an @code{AM_} variable or of a user
+variable. For instance, the @code{mumble_LDADD} per-target variable
+overrides the makefile-wide @code{LDADD} variable (which is not a user
+variable), and @code{mumble_LIBADD} exists only as a per-target
+variable. @xref{Program and Library Variables}.
+
+
+@node Renamed Objects
+@section Why are object files sometimes renamed?
+
+This happens when per-target compilation flags are used. Object
+files need to be renamed just in case they would clash with object
+files compiled from the same sources, but with different flags.
+Consider the following example.
+
+@example
+bin_PROGRAMS = true false
+true_SOURCES = generic.c
+true_CPPFLAGS = -DEXIT_CODE=0
+false_SOURCES = generic.c
+false_CPPFLAGS = -DEXIT_CODE=1
+@end example
+
+@noindent
+Obviously the two programs are built from the same source, but it
+would be bad if they shared the same object, because @file{generic.o}
+cannot be built with both @samp{-DEXIT_CODE=0} @emph{and}
+@samp{-DEXIT_CODE=1}. Therefore @command{automake} outputs rules to
+build two different objects: @file{true-generic.o} and
+@file{false-generic.o}.
+
+@command{automake} doesn't actually look whether source files are
+shared to decide if it must rename objects. It will just rename all
+objects of a target as soon as it sees per-target compilation flags
+used.
+
+It's OK to share object files when per-target compilation flags are not
+used. For instance, @file{true} and @file{false} will both use
+@file{version.o} in the following example.
+
+@example
+AM_CPPFLAGS = -DVERSION=1.0
+bin_PROGRAMS = true false
+true_SOURCES = true.c version.c
+false_SOURCES = false.c version.c
+@end example
+
+Note that the renaming of objects is also affected by the
+@code{_SHORTNAME} variable (@pxref{Program and Library Variables}).
+
+
+@node Per-Object Flags
+@section Per-Object Flags Emulation
+@cindex Per-object flags, emulated
+
+@display
+One of my source files needs to be compiled with different flags. How
+do I do?
+@end display
+
+Automake supports per-program and per-library compilation flags (see
+@ref{Program and Library Variables} and @ref{Flag Variables
+Ordering}). With this you can define compilation flags that apply to
+all files compiled for a target. For instance, in
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = foo.c foo.h bar.c bar.h main.c
+foo_CFLAGS = -some -flags
+@end example
+
+@noindent
+@file{foo-foo.o}, @file{foo-bar.o}, and @file{foo-main.o} will all be
+compiled with @samp{-some -flags}. (If you wonder about the names of
+these object files, see @ref{Renamed Objects}.) Note that
+@code{foo_CFLAGS} gives the flags to use when compiling all the C
+sources of the @emph{program} @code{foo}, it has nothing to do with
+@file{foo.c} or @file{foo-foo.o} specifically.
+
+What if @file{foo.c} needs to be compiled into @file{foo.o} using some
+specific flags, that none of the other files requires? Obviously
+per-program flags are not directly applicable here. Something like
+per-object flags are expected, i.e., flags that would be used only
+when creating @file{foo-foo.o}. Automake does not support that,
+however this is easy to simulate using a library that contains only
+that object, and compiling this library with per-library flags.
+
+@example
+bin_PROGRAMS = foo
+foo_SOURCES = bar.c bar.h main.c
+foo_CFLAGS = -some -flags
+foo_LDADD = libfoo.a
+noinst_LIBRARIES = libfoo.a
+libfoo_a_SOURCES = foo.c foo.h
+libfoo_a_CFLAGS = -some -other -flags
+@end example
+
+Here @file{foo-bar.o} and @file{foo-main.o} will all be
+compiled with @samp{-some -flags}, while @file{libfoo_a-foo.o} will
+be compiled using @samp{-some -other -flags}. Eventually, all
+three objects will be linked to form @file{foo}.
+
+This trick can also be achieved using Libtool convenience libraries,
+for instance @samp{noinst_LTLIBRARIES = libfoo.la} (@pxref{Libtool
+Convenience Libraries}).
+
+Another tempting idea to implement per-object flags is to override the
+compile rules @command{automake} would output for these files.
+Automake will not define a rule for a target you have defined, so you
+could think about defining the @samp{foo-foo.o: foo.c} rule yourself.
+We recommend against this, because this is error prone. For instance,
+if you add such a rule to the first example, it will break the day you
+decide to remove @code{foo_CFLAGS} (because @file{foo.c} will then be
+compiled as @file{foo.o} instead of @file{foo-foo.o}, @pxref{Renamed
+Objects}). Also in order to support dependency tracking, the two
+@file{.o}/@file{.obj} extensions, and all the other flags variables
+involved in a compilation, you will end up modifying a copy of the
+rule previously output by @command{automake} for this file. If a new
+release of Automake generates a different rule, your copy will need to
+be updated by hand.
+
+@node Multiple Outputs
+@section Handling Tools that Produce Many Outputs
+@cindex multiple outputs, rules with
+@cindex many outputs, rules with
+@cindex rules with multiple outputs
+
+This section describes a @command{make} idiom that can be used when a
+tool produces multiple output files. It is not specific to Automake
+and can be used in ordinary @file{Makefile}s.
+
+Suppose we have a program called @command{foo} that will read one file
+called @file{data.foo} and produce two files named @file{data.c} and
+@file{data.h}. We want to write a @file{Makefile} rule that captures
+this one-to-two dependency.
+
+The naive rule is incorrect:
+
+@example
+# This is incorrect.
+data.c data.h: data.foo
+ foo data.foo
+@end example
+
+@noindent
+What the above rule really says is that @file{data.c} and
+@file{data.h} each depend on @file{data.foo}, and can each be built by
+running @samp{foo data.foo}. In other words it is equivalent to:
+
+@example
+# We do not want this.
+data.c: data.foo
+ foo data.foo
+data.h: data.foo
+ foo data.foo
+@end example
+
+@noindent
+which means that @command{foo} can be run twice. Usually it will not
+be run twice, because @command{make} implementations are smart enough
+to check for the existence of the second file after the first one has
+been built; they will therefore detect that it already exists.
+However there are a few situations where it can run twice anyway:
+
+@itemize
+@item
+The most worrying case is when running a parallel @command{make}. If
+@file{data.c} and @file{data.h} are built in parallel, two @samp{foo
+data.foo} commands will run concurrently. This is harmful.
+@item
+Another case is when the dependency (here @file{data.foo}) is
+(or depends upon) a phony target.
+@end itemize
+
+A solution that works with parallel @command{make} but not with
+phony dependencies is the following:
+
+@example
+data.c data.h: data.foo
+ foo data.foo
+data.h: data.c
+@end example
+
+@noindent
+The above rules are equivalent to
+
+@example
+data.c: data.foo
+ foo data.foo
+data.h: data.foo data.c
+ foo data.foo
+@end example
+
+@noindent
+therefore a parallel @command{make} will have to serialize the builds
+of @file{data.c} and @file{data.h}, and will detect that the second is
+no longer needed once the first is over.
+
+Using this pattern is probably enough for most cases. However it does
+not scale easily to more output files (in this scheme all output files
+must be totally ordered by the dependency relation), so we will
+explore a more complicated solution.
+
+Another idea is to write the following:
+
+@example
+# There is still a problem with this one.
+data.c: data.foo
+ foo data.foo
+data.h: data.c
+@end example
+
+@noindent
+The idea is that @samp{foo data.foo} is run only when @file{data.c}
+needs to be updated, but we further state that @file{data.h} depends
+upon @file{data.c}. That way, if @file{data.h} is required and
+@file{data.foo} is out of date, the dependency on @file{data.c} will
+trigger the build.
+
+This is almost perfect, but suppose we have built @file{data.h} and
+@file{data.c}, and then we erase @file{data.h}. Then, running
+@samp{make data.h} will not rebuild @file{data.h}. The above rules
+just state that @file{data.c} must be up-to-date with respect to
+@file{data.foo}, and this is already the case.
+
+What we need is a rule that forces a rebuild when @file{data.h} is
+missing. Here it is:
+
+@example
+data.c: data.foo
+ foo data.foo
+data.h: data.c
+## Recover from the removal of $@@
+ @@if test -f $@@; then :; else \
+ rm -f data.c; \
+ $(MAKE) $(AM_MAKEFLAGS) data.c; \
+ fi
+@end example
+
+The above scheme can be extended to handle more outputs and more
+inputs. One of the outputs is selected to serve as a witness to the
+successful completion of the command, it depends upon all inputs, and
+all other outputs depend upon it. For instance, if @command{foo}
+should additionally read @file{data.bar} and also produce
+@file{data.w} and @file{data.x}, we would write:
+
+@example
+data.c: data.foo data.bar
+ foo data.foo data.bar
+data.h data.w data.x: data.c
+## Recover from the removal of $@@
+ @@if test -f $@@; then :; else \
+ rm -f data.c; \
+ $(MAKE) $(AM_MAKEFLAGS) data.c; \
+ fi
+@end example
+
+However there are now three minor problems in this setup. One is related
+to the timestamp ordering of @file{data.h}, @file{data.w},
+@file{data.x}, and @file{data.c}. Another one is a race condition
+if a parallel @command{make} attempts to run multiple instances of the
+recover block at once. Finally, the recursive rule breaks @samp{make -n}
+when run with GNU @command{make} (as well as some other @command{make}
+implementations), as it may remove @file{data.h} even when it should not
+(@pxref{MAKE Variable, , How the @code{MAKE} Variable Works, make,
+The GNU Make Manual}).
+
+Let us deal with the first problem. @command{foo} outputs four files,
+but we do not know in which order these files are created. Suppose
+that @file{data.h} is created before @file{data.c}. Then we have a
+weird situation. The next time @command{make} is run, @file{data.h}
+will appear older than @file{data.c}, the second rule will be
+triggered, a shell will be started to execute the @samp{if@dots{}fi}
+command, but actually it will just execute the @code{then} branch,
+that is: nothing. In other words, because the witness we selected is
+not the first file created by @command{foo}, @command{make} will start
+a shell to do nothing each time it is run.
+
+A simple riposte is to fix the timestamps when this happens.
+
+@example
+data.c: data.foo data.bar
+ foo data.foo data.bar
+data.h data.w data.x: data.c
+ @@if test -f $@@; then \
+ touch $@@; \
+ else \
+## Recover from the removal of $@@
+ rm -f data.c; \
+ $(MAKE) $(AM_MAKEFLAGS) data.c; \
+ fi
+@end example
+
+Another solution is to use a different and dedicated file as witness,
+rather than using any of @command{foo}'s outputs.
+
+@example
+data.stamp: data.foo data.bar
+ @@rm -f data.tmp
+ @@touch data.tmp
+ foo data.foo data.bar
+ @@mv -f data.tmp $@@
+data.c data.h data.w data.x: data.stamp
+## Recover from the removal of $@@
+ @@if test -f $@@; then :; else \
+ rm -f data.stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) data.stamp; \
+ fi
+@end example
+
+@file{data.tmp} is created before @command{foo} is run, so it has a
+timestamp older than output files output by @command{foo}. It is then
+renamed to @file{data.stamp} after @command{foo} has run, because we
+do not want to update @file{data.stamp} if @command{foo} fails.
+
+This solution still suffers from the second problem: the race
+condition in the recover rule. If, after a successful build, a user
+erases @file{data.c} and @file{data.h}, and runs @samp{make -j}, then
+@command{make} may start both recover rules in parallel. If the two
+instances of the rule execute @samp{$(MAKE) $(AM_MAKEFLAGS)
+data.stamp} concurrently the build is likely to fail (for instance, the
+two rules will create @file{data.tmp}, but only one can rename it).
+
+Admittedly, such a weird situation does not arise during ordinary
+builds. It occurs only when the build tree is mutilated. Here
+@file{data.c} and @file{data.h} have been explicitly removed without
+also removing @file{data.stamp} and the other output files.
+@code{make clean; make} will always recover from these situations even
+with parallel makes, so you may decide that the recover rule is solely
+to help non-parallel make users and leave things as-is. Fixing this
+requires some locking mechanism to ensure only one instance of the
+recover rule rebuilds @file{data.stamp}. One could imagine something
+along the following lines.
+
+@example
+data.c data.h data.w data.x: data.stamp
+## Recover from the removal of $@@
+ @@if test -f $@@; then :; else \
+ trap 'rm -rf data.lock data.stamp' 1 2 13 15; \
+## mkdir is a portable test-and-set
+ if mkdir data.lock 2>/dev/null; then \
+## This code is being executed by the first process.
+ rm -f data.stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) data.stamp; \
+ result=$$?; rm -rf data.lock; exit $$result; \
+ else \
+## This code is being executed by the follower processes.
+## Wait until the first process is done.
+ while test -d data.lock; do sleep 1; done; \
+## Succeed if and only if the first process succeeded.
+ test -f data.stamp; \
+ fi; \
+ fi
+@end example
+
+Using a dedicated witness, like @file{data.stamp}, is very handy when
+the list of output files is not known beforehand. As an illustration,
+consider the following rules to compile many @file{*.el} files into
+@file{*.elc} files in a single command. It does not matter how
+@code{ELFILES} is defined (as long as it is not empty: empty targets
+are not accepted by POSIX).
+
+@example
+ELFILES = one.el two.el three.el @dots{}
+ELCFILES = $(ELFILES:=c)
+
+elc-stamp: $(ELFILES)
+ @@rm -f elc-temp
+ @@touch elc-temp
+ $(elisp_comp) $(ELFILES)
+ @@mv -f elc-temp $@@
+
+$(ELCFILES): elc-stamp

+## This code is being executed by the first process.
+ rm -f elc-stamp; \
+ $(MAKE) $(AM_MAKEFLAGS) elc-stamp; \
+ rmdir elc-lock; \
+ else \
+## This code is being executed by the follower processes.
+## Wait until the first process is done.
+ while test -d elc-lock; do sleep 1; done; \
+## Succeed if and only if the first process succeeded.
+ test -f elc-stamp; exit $$?; \
+@c $$
+ fi; \
+ fi
+@end example
+
+These solutions all still suffer from the third problem, namely that
+they break the promise that @samp{make -n} should not cause any actual
+changes to the tree. For those solutions that do not create lock files,
+it is possible to split the recover rules into two separate recipe
+commands, one of which does all work but the recursion, and the
+other invokes the recursive @samp{$(MAKE)}. The solutions involving
+locking could act upon the contents of the @samp{MAKEFLAGS} variable,
+but parsing that portably is not easy (@pxref{The Make Macro MAKEFLAGS,,,
+autoconf, The Autoconf Manual}). Here is an example:
+
+@example
+ELFILES = one.el two.el three.el @dots{}
+ELCFILES = $(ELFILES:=c)

+@end example
+
+For completeness it should be noted that GNU @command{make} is able to
+express rules with multiple output files using pattern rules
+(@pxref{Pattern Examples, , Pattern Rule Examples, make, The GNU Make
+Manual}). We do not discuss pattern rules here because they are not
+portable, but they can be convenient in packages that assume GNU
+@command{make}.
+
+
+@node Hard-Coded Install Paths
+@section Installing to Hard-Coded Locations
+
+@display
+My package needs to install some configuration file. I tried to use
+the following rule, but @samp{make distcheck} fails. Why?
+
+@example
+# Do not do this.
+install-data-local:
+ $(INSTALL_DATA) $(srcdir)/afile $(DESTDIR)/etc/afile
+@end example
+@end display
+
+@display
+My package needs to populate the installation directory of another
+package at install-time. I can easily compute that installation
+directory in @file{configure}, but if I install files therein,
+@samp{make distcheck} fails. How else should I do?
+@end display
+
+These two setups share their symptoms: @samp{make distcheck} fails
+because they are installing files to hard-coded paths. In the later
+case the path is not really hard-coded in the package, but we can
+consider it to be hard-coded in the system (or in whichever tool that
+supplies the path). As long as the path does not use any of the
+standard directory variables (@samp{$(prefix)}, @samp{$(bindir)},
+@samp{$(datadir)}, etc.), the effect will be the same:
+user-installations are impossible.
+
+As a (non-root) user who wants to install a package, you usually have no
+right to install anything in @file{/usr} or @file{/usr/local}. So you
+do something like @samp{./configure --prefix ~/usr} to install a
+package in your own @file{~/usr} tree.
+
+If a package attempts to install something to some hard-coded path
+(e.g., @file{/etc/afile}), regardless of this @option{--prefix} setting,
+then the installation will fail. @samp{make distcheck} performs such
+a @option{--prefix} installation, hence it will fail too.
+
+Now, there are some easy solutions.
+
+The above @code{install-data-local} example for installing
+@file{/etc/afile} would be better replaced by
+
+@example
+sysconf_DATA = afile
+@end example
+
+@noindent
+by default @code{sysconfdir} will be @samp{$(prefix)/etc}, because
+this is what the GNU Standards require. When such a package is
+installed on an FHS compliant system, the installer will have to set
+@samp{--sysconfdir=/etc}. As the maintainer of the package you
+should not be concerned by such site policies: use the appropriate
+standard directory variable to install your files so that the installer
+can easily redefine these variables to match their site conventions.
+
+Installing files that should be used by another package is slightly
+more involved. Let's take an example and assume you want to install
+a shared library that is a Python extension module. If you ask Python
+where to install the library, it will answer something like this:
+
+@example
+% @kbd{python -c 'from distutils import sysconfig;
+ print sysconfig.get_python_lib(1,0)'}
+/usr/lib/python2.5/site-packages
+@end example
+
+If you indeed use this absolute path to install your shared library,
+non-root users will not be able to install the package, hence
+distcheck fails.
+
+Let's do better. The @samp{sysconfig.get_python_lib()} function
+actually accepts a third argument that will replace Python's
+installation prefix.
+
+@example
+% @kbd{python -c 'from distutils import sysconfig;
+ print sysconfig.get_python_lib(1,0,"$@{exec_prefix@}")'}
+$@{exec_prefix@}/lib/python2.5/site-packages
+@end example
+
+You can also use this new path. If you do
+@itemize @bullet
+@item
+root users can install your package with the same @option{--prefix}
+as Python (you get the behavior of the previous attempt)
+
+@item
+non-root users can install your package too, they will have the
+extension module in a place that is not searched by Python but they
+can work around this using environment variables (and if you installed
+scripts that use this shared library, it's easy to tell Python were to
+look in the beginning of your script, so the script works in both
+cases).
+@end itemize
+
+The @code{AM_PATH_PYTHON} macro uses similar commands to define
+@samp{$(pythondir)} and @samp{$(pyexecdir)} (@pxref{Python}).
+
+Of course not all tools are as advanced as Python regarding that
+substitution of @var{prefix}. So another strategy is to figure the
+part of the installation directory that must be preserved. For
+instance, here is how @code{AM_PATH_LISPDIR} (@pxref{Emacs Lisp})
+computes @samp{$(lispdir)}:
+
+@example
+$EMACS -batch -q -eval '(while load-path
+ (princ (concat (car load-path) "\n"))
+ (setq load-path (cdr load-path)))' >conftest.out
+lispdir=`sed -n
+ -e 's,/$,,'
+ -e '/.*\/lib\/x*emacs\/site-lisp$/@{
+ s,.*/lib/\(x*emacs/site-lisp\)$,$@{libdir@}/\1,;p;q;
+ @}'
+ -e '/.*\/share\/x*emacs\/site-lisp$/@{
+ s,.*/share/\(x*emacs/site-lisp\),$@{datarootdir@}/\1,;p;q;
+ @}'
+ conftest.out`
+@end example
+
+I.e., it just picks the first directory that looks like
+@file{*/lib/*emacs/site-lisp} or @file{*/share/*emacs/site-lisp} in
+the search path of emacs, and then substitutes @samp{$@{libdir@}} or
+@samp{$@{datadir@}} appropriately.
+
+The emacs case looks complicated because it processes a list and
+expects two possible layouts, otherwise it's easy, and the benefits for
+non-root users are really worth the extra @command{sed} invocation.

+@node Debugging Make Rules
+@section Debugging Make Rules
+@cindex debugging rules
+@cindex rules, debugging
+
+The rules and dependency trees generated by @command{automake} can get
+rather complex, and leave the developer head-scratching when things
+don't work as expected. Besides the debug options provided by the
+@command{make} command (@pxref{Options Summary,,, make, The GNU Make
+Manual}), here's a couple of further hints for debugging makefiles
+generated by @command{automake} effectively:
+
+@itemize
+@item
+If less verbose output has been enabled in the package with the
+@samp{silent-rules} option (@pxref{Options}), you can use
+@code{make V=1} to see the commands being executed.
+@item
+@code{make -n} can help show what would be done without actually doing
+it. Note however, that this will @emph{still execute} commands prefixed
+with @samp{+}, and, when using GNU @command{make}, commands that contain
+the strings @samp{$(MAKE)} or @samp{$@{MAKE@}} (@pxref{Instead of
+Execution,,, make, The GNU Make Manual}).
+Typically, this is helpful to show what recursive rules would do, but it
+means that, in your own rules, you should not mix such recursion with
+actions that change any files.@footnote{Automake's @samp{dist} and
+@samp{distcheck} rules had a bug in this regard in that they created
+directories even with @option{-n}, but this has been fixed in Automake
+1.11.} Furthermore, note that GNU @command{make} will update
+prerequisites for the @file{Makefile} file itself even with @option{-n}
+(@pxref{Remaking Makefiles,,, make, The GNU Make Manual}).
+@item
+@code{make SHELL="/bin/bash -vx"} can help debug complex rules.
+@xref{The Make Macro SHELL,,, autoconf, The Autoconf Manual}, for some
+portability quirks associated with this construct.
+@item
+@code{echo 'print: ; @@echo "$(VAR)"' | make -f Makefile -f - print}
+can be handy to examine the expanded value of variables. You may need
+to use a target other than @samp{print} if that is already used or a
+file with that name exists.
+@item
+@url{http://bashdb.sourceforge.net/@/remake/} provides a modified
+GNU @command{make} command called @command{remake} that copes with
+complex GNU @command{make}-specific Makefiles and allows to trace
+execution, examine variables, and call rules interactively, much like
+a debugger.

+@node Reporting Bugs
+@section Reporting Bugs
+
+Most nontrivial software has bugs. Automake is no exception. Although
+we cannot promise we can or will fix a bug, and we might not even agree
+that it is a bug, we want to hear about problems you encounter. Often we
+agree they are bugs and want to fix them.
+
+To make it possible for us to fix a bug, please report it. In order to
+do so effectively, it helps to know when and how to do it.
+
+Before reporting a bug, it is a good idea to see if it is already known.
+You can look at the @uref{http://debbugs.gnu.org/, GNU Bug Tracker}
+and the @uref{http://lists.gnu.org/@/archive/@/html/@/bug-automake/,
+bug-automake mailing list archives} for previous bug reports. We
+previously used a
+@uref{http://sourceware.org/@/cgi-bin/@/gnatsweb.pl?database=automake,
+Gnats database} for bug tracking, so some bugs might have been reported
+there already. Please do not use it for new bug reports, however.
+
+If the bug is not already known, it should be reported. It is very
+important to report bugs in a way that is useful and efficient. For
+this, please familiarize yourself with
+@uref{http://www.chiark.greenend.org.uk/@/~sgtatham/@/bugs.html, How to
+Report Bugs Effectively} and
+@uref{http://catb.org/@/~esr/@/faqs/@/smart-questions.html, How to Ask
+Questions the Smart Way}. This helps you and developers to save time
+which can then be spent on fixing more bugs and implementing more
+features.
+
+For a bug report, a feature request or other suggestions, please send
+email to @email{@value{PACKAGE_BUGREPORT}}. This will then open a new
+bug in the @uref{http://debbugs.gnu.org/@/automake, bug tracker}. Be
+sure to include the versions of Autoconf and Automake that you use.
+Ideally, post a minimal @file{Makefile.am} and @file{configure.ac} that
+reproduces the problem you encounter. If you have encountered test
+suite failures, please attach the @file{test-suite.log} file.

+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject. (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.) The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License. If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant. The Document may contain zero
+Invariant Sections. If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License. A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters. A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text. A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification. Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page. For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+The ``publisher'' means any person or entity that distributes copies
+of the Document to the public.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language. (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.) To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document. These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License. You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover. Both covers must also clearly and legibly identify
+you as the publisher of these copies. The front cover must present
+the full title with all words of the title equally prominent and
+visible. You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it. In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document). You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add
+to it an item stating at least the title, year, new authors, and
+publisher of the Modified Version as given on the Title Page. If
+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on. These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at
+least four years before the Document itself, or if the original
+publisher of the version it refers to gives permission.
+
+@item
+For any section Entitled ``Acknowledgements'' or ``Dedications'', Preserve
+the Title of the section, and preserve in the section all the
+substance and tone of each of the contributor acknowledgements and/or
+dedications given therein.
+
+@item
+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles. Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity. If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy. If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''. You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included in an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers. In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense, or distribute it is void, and
+will automatically terminate your rights under this License.
+
+However, if you cease all violation of this License, then your license
+from a particular copyright holder is reinstated (a) provisionally,
+unless and until the copyright holder explicitly and finally
+terminates your license, and (b) permanently, if the copyright holder
+fails to notify you of the violation by some reasonable means prior to
+60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, receipt of a copy of some or all of the same material does
+not give you any rights to use it.
+
+@item
+FUTURE REVISIONS OF THIS LICENSE
+
+The Free Software Foundation may publish new, revised versions
+of the GNU Free Documentation License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns. See
+@uref{http://www.gnu.org/copyleft/}.
+
+Each version of the License is given a distinguishing version number.
+If the Document specifies that a particular numbered version of this
+License ``or any later version'' applies to it, you have the option of
+following the terms and conditions either of that specified version or
+of any later version that has been published (not as a draft) by the
+Free Software Foundation. If the Document does not specify a version
+number of this License, you may choose any version ever published (not
+as a draft) by the Free Software Foundation. If the Document
+specifies that a proxy can decide which future versions of this
+License can be used, that proxy's public statement of acceptance of a
+version permanently authorizes you to choose that version for the
+Document.
+
+@item
+RELICENSING
+
+``Massive Multiauthor Collaboration Site'' (or ``MMC Site'') means any
+World Wide Web server that publishes copyrightable works and also
+provides prominent facilities for anybody to edit those works. A
+public wiki that anybody can edit is an example of such a server. A
+``Massive Multiauthor Collaboration'' (or ``MMC'') contained in the
+site means any set of copyrightable works thus published on the MMC
+site.
+
+``CC-BY-SA'' means the Creative Commons Attribution-Share Alike 3.0
+license published by Creative Commons Corporation, a not-for-profit
+corporation with a principal place of business in San Francisco,
+California, as well as future copyleft versions of that license
+published by that same organization.
+
+``Incorporate'' means to publish or republish a Document, in whole or
+in part, as part of another Document.
+
+An MMC is ``eligible for relicensing'' if it is licensed under this
+License, and if all works that were first published under this License
+somewhere other than this MMC, and subsequently incorporated in whole
+or in part into the MMC, (1) had no cover texts or invariant sections,
+and (2) were thus incorporated prior to November 1, 2008.
+
+The operator of an MMC Site may republish an MMC contained in the site
+under CC-BY-SA on the same site at any time before August 1, 2009,
+provided the MMC is eligible for relicensing.

+@heading ADDENDUM: How to use this License for your documents
+
+To use this License in a document you have written, include a copy of
+the License in the document and put the following copyright and
+license notices just after the title page:
+
+@smallexample
+@group
+ Copyright (C) @var{year} @var{your name}.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.3
+ or any later version published by the Free Software Foundation;
+ with no Invariant Sections, no Front-Cover Texts, and no Back-Cover
+ Texts. A copy of the license is included in the section entitled ``GNU
+ Free Documentation License''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with@dots{}Texts.'' line with this:
+
+@smallexample
+@group
+ with the Invariant Sections being @var{list their titles}, with
+ the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+ being @var{list}.
+@end group
+@end smallexample
+
+If you have Invariant Sections without Cover Texts, or some other
+combination of the three, merge those two alternatives to suit the
+situation.
+
+If your document contains nontrivial examples of program code, we
+recommend releasing these examples in parallel under your choice of
+free software license, such as the GNU General Public License,
+to permit their use in free software.

+=head1 DESCRIPTION
+
+This perl module provides support functions for handling diagnostic
+channels in programs. Channels can be registered to convey fatal,
+error, warning, or debug messages. Each channel has various options
+(e.g. is the channel silent, should duplicate messages be removed,
+etc.) that can also be overridden on a per-message basis.

+
+=item C<UP_NONE>, C<UP_TEXT>, C<UP_LOC_TEXT>
+
+Possible values for the C<uniq_part> options. This selects the part
+of the message that should be considered when filtering out duplicates.
+If C<UP_LOC_TEXT> is used, the location and the explanation message
+are used for filtering. If C<UP_TEXT> is used, only the explanation
+message is used (so the same message will be filtered out if it appears
+at different locations). C<UP_NONE> means that duplicate messages
+should be output.

+
+Possible values for the C<uniq_scope> options.
+Use C<US_GLOBAL> for error messages that should be printed only
+once during the execution of the program, C<US_LOCAL> for message that
+should be printed only once per file. (Actually, C<Channels> does not
+do this now when files are changed, it relies on you calling
+C<reset_local_duplicates> when this happens.)

+
+=head2 Options
+
+Channels accept the options described below. These options can be
+passed as a hash to the C<register_channel>, C<setup_channel>, and C<msg>
+functions. The possible keys, with their default value are:
+
+=over
+
+=item C<type =E<gt> 'warning'>
+
+The type of the channel. One of C<'debug'>, C<'warning'>, C<'error'>, or
+C<'fatal'>. Fatal messages abort the program when they are output.
+Error messages update the exit status. Debug and warning messages are
+harmless, except that warnings are treated as errors if
+C<$warnings_are_errors> is set.
+
+=item C<exit_code =E<gt> 1>
+
+The value to update C<$exit_code> with when a fatal or error message
+is emitted. C<$exit_code> is also updated for warnings output
+when C<$warnings_are_errors> is set.
+
+=item C<file =E<gt> \*STDERR>
+
+The file where the error should be output.
+
+=item C<silent =E<gt> 0>
+
+Whether the channel should be silent. Use this do disable a
+category of warning, for instance.
+
+=item C<ordered =E<gt> 1>
+
+Whether, with multi-threaded execution, the message should be queued
+for ordered output.
+
+=item C<uniq_part =E<gt> UP_LOC_TEXT>
+
+The part of the message subject to duplicate filtering. See the
+documentation for the C<UP_NONE>, C<UP_TEXT>, and C<UP_LOC_TEXT>
+constants above.
+
+C<uniq_part> can also be set to an arbitrary string that will be used
+instead of the message when considering duplicates.
+
+=item C<uniq_scope =E<gt> US_LOCAL>
+
+The scope of duplicate filtering. See the documentation for the
+C<US_LOCAL>, and C<US_GLOBAL> constants above.
+
+=item C<header =E<gt> ''>
+
+A string to prepend to each message emitted through this channel.
+With partial messages, only the first part will have C<header>
+prepended.
+
+=item C<footer =E<gt> ''>
+
+A string to append to each message emitted through this channel.
+With partial messages, only the final part will have C<footer>
+appended.
+
+=item C<backtrace =E<gt> 0>
+
+Die with a stack backtrace after displaying the message.
+
+=item C<partial =E<gt> 0>
+
+When set, indicates a partial message that should
+be output along with the next message with C<partial> unset.
+Several partial messages can be stacked this way.
+
+Duplicate filtering will apply to the I<global> message resulting from
+all I<partial> messages, using the options from the last (non-partial)
+message. Linking associated messages is the main reason to use this
+option.
+
+For instance the following messages
+
+ msg 'channel', 'foo:2', 'redefinition of A ...';
+ msg 'channel', 'foo:1', '... A previously defined here';
+ msg 'channel', 'foo:3', 'redefinition of A ...';
+ msg 'channel', 'foo:1', '... A previously defined here';
+
+will result in
+
+ foo:2: redefinition of A ...
+ foo:1: ... A previously defined here
+ foo:3: redefinition of A ...
+
+where the duplicate "I<... A previously defined here>" has been
+filtered out.
+
+Linking these messages using C<partial> as follows will prevent the
+fourth message to disappear.
+
+ msg 'channel', 'foo:2', 'redefinition of A ...', partial => 1;
+ msg 'channel', 'foo:1', '... A previously defined here';
+ msg 'channel', 'foo:3', 'redefinition of A ...', partial => 1;
+ msg 'channel', 'foo:1', '... A previously defined here';
+
+Note that because the stack of C<partial> messages is printed with the
+first non-C<partial> message, most options of C<partial> messages will
+be ignored.

+=item C<msg ($channel, $location, $message, [%options])>
+
+Emit a message on C<$channel>, overriding some options of the channel with
+those specified in C<%options>. Obviously C<$channel> must have been
+registered with C<register_channel>.
+
+C<$message> is the text of the message, and C<$location> is a location
+associated to the message.
+
+For instance to complain about some unused variable C<mumble>
+declared at line 10 in F<foo.c>, one could do:
+
+ msg 'unused', 'foo.c:10', "unused variable 'mumble'";
+
+If channel C<unused> is not silent (and if this message is not a duplicate),
+the following would be output:
+
+ foo.c:10: unused variable 'mumble'
+
+C<$location> can also be an instance of C<Automake::Location>. In this
+case, the stack of contexts will be displayed in addition.
+
+If C<$message> contains newline characters, C<$location> is prepended
+to each line. For instance,
+
+ msg 'error', 'somewhere', "1st line\n2nd line";
+
+becomes
+
+ somewhere: 1st line
+ somewhere: 2nd line
+
+If C<$location> is an empty string, it is replaced by the name of the
+program. Actually, if you don't use C<%options>, you can even
+elide the empty C<$location>. Thus

+ msg 'fatal', '', 'fatal error';

+=head1 DESCRIPTION
+
+A C<Condition> is a conjunction of conditionals (i.e., atomic conditions
+defined in F<configure.ac> by C<AM_CONDITIONAL>. In Automake they
+are used to represent the conditions into which F<Makefile> variables and
+F<Makefile> rules are defined.
+
+If the variable C<VAR> is defined as
+
+ if COND1
+ if COND2
+ VAR = value
+ endif
+ endif
+
+then it will be associated a C<Condition> created with
+the following statement.
+
+ new Automake::Condition "COND1_TRUE", "COND2_TRUE";
+
+Remember that a C<Condition> is a I<conjunction> of conditionals, so
+the above C<Condition> means C<VAR> is defined when C<COND1>
+B<and> C<COND2> are true. There is no way to express disjunctions
+(i.e., I<or>s) with this class (but see L<DisjConditions>).
+
+Another point worth to mention is that each C<Condition> object is
+unique with respect to its conditionals. Two C<Condition> objects
+created for the same set of conditionals will have the same address.
+This makes it easy to compare C<Condition>s: just compare the
+references.
+
+ my $c1 = new Automake::Condition "COND1_TRUE", "COND2_TRUE";
+ my $c2 = new Automake::Condition "COND1_TRUE", "COND2_TRUE";
+ $c1 == $c2; # True!
+
+=head2 Methods
+
+=over 4
+
+=item C<$cond = new Automake::Condition [@conds]>
+
+Return a C<Condition> objects for the conjunctions of conditionals
+listed in C<@conds> as strings.
+
+An item in C<@conds> should be either C<"FALSE">, C<"TRUE">, or have
+the form C<"NAME_FALSE"> or C<"NAME_TRUE"> where C<NAME> can be
+anything (in practice C<NAME> should be the name of a conditional
+declared in F<configure.ac> with C<AM_CONDITIONAL>, but it's not
+C<Automake::Condition>'s responsibility to ensure this).
+
+An empty C<@conds> means C<"TRUE">.
+
+As explained previously, the reference (object) returned is unique
+with respect to C<@conds>. For this purpose, duplicate elements are
+ignored, and C<@conds> is rewritten as C<("FALSE")> if it contains
+C<"FALSE"> or two contradictory conditionals (such as C<"NAME_FALSE">
+and C<"NAME_TRUE">.)
+
+Therefore the following two statements create the same object (they
+both create the C<"FALSE"> condition).
+
+ my $c3 = new Automake::Condition "COND1_TRUE", "COND1_FALSE";
+ my $c4 = new Automake::Condition "COND2_TRUE", "FALSE";
+ $c3 == $c4; # True!
+ $c3 == FALSE; # True!

+=head1 DESCRIPTION
+
+A C<DisjConditions> is a disjunction of C<Condition>s. In Automake
+they are used to represent the conditions into which Makefile
+variables and Makefile rules are defined.
+
+If the variable C<VAR> is defined as
+
+ if COND1
+ if COND2
+ VAR = value1
+ endif
+ endif
+ if !COND3
+ if COND4
+ VAR = value2
+ endif
+ endif
+
+then it will be associated a C<DisjConditions> created with
+the following statement.
+
+ new Automake::DisjConditions
+ (new Automake::Condition ("COND1_TRUE", "COND2_TRUE"),
+ new Automake::Condition ("COND3_FALSE", "COND4_TRUE"));
+
+As you can see, a C<DisjConditions> is made from a list of
+C<Condition>s. Since C<DisjConditions> is a disjunction, and
+C<Condition> is a conjunction, the above can be read as
+follows.
+
+ (COND1 and COND2) or ((not COND3) and COND4)
+
+That's indeed the condition in which C<VAR> has a value.
+
+Like C<Condition> objects, a C<DisjConditions> object is unique
+with respect to its conditions. Two C<DisjConditions> objects created
+for the same set of conditions will have the same address. This makes
+it easy to compare C<DisjConditions>s: just compare the references.

+
+=head1 DESCRIPTION
+
+C<Location> objects are used to keep track of locations in Automake,
+and used to produce diagnostics.
+
+A C<Location> object is made of two parts: a location string, and
+a stack of contexts.
+
+For instance if C<VAR> is defined at line 1 in F<bar.h> which was
+included at line 14 in F<foo.c>, then the location string should be
+C<"bar.h:10"> and the context should be the pair (C<"foo.c:14">,
+C<"included from here">).
+
+Section I<SYNOPSIS> shows how to setup such a C<Location>, and access
+the location string or the stack of contexts.
+
+You can pass a C<Location> to C<Automake::Channels::msg>.

+
+Automake::Rule - support for rules definitions
+
+=head1 SYNOPSIS
+
+ use Automake::Rule;
+ use Automake::RuleDef;
+
+
+=head1 DESCRIPTION
+
+This package provides support for Makefile rule definitions.
+
+An C<Automake::Rule> is a rule name associated to possibly
+many conditional definitions. These definitions are instances
+of C<Automake::RuleDef>.
+
+Therefore obtaining the value of a rule under a given
+condition involves two lookups. One to look up the rule,
+and one to look up the conditional definition:
+
+ my $rule = rule $name;
+ if ($rule)
+ {
+ my $def = $rule->def ($cond);
+ if ($def)
+ {
+ return $def->location;
+ }
+ ...
+ }
+ ...
+
+when it is known that the rule and the definition
+being looked up exist, the above can be simplified to
+
+ return rule ($name)->def ($cond)->location; # do not write this.
+
+but is better written
+
+ return rrule ($name)->rdef ($cond)->location;
+
+or even
+
+ return rruledef ($name, $cond)->location;
+
+The I<r> variants of the C<rule>, C<def>, and C<ruledef> methods add
+an extra test to ensure that the lookup succeeded, and will diagnose
+failures as internal errors (with a message which is much more
+informative than Perl's warning about calling a method on a
+non-object).

+=item C<%dependencies>
+
+Holds the dependencies of targets which dependencies are factored.
+Typically, C<.PHONY> will appear in plenty of F<*.am> files, but must
+be output once. Arguably all pure dependencies could be subject to
+this factoring, but it is not unpleasant to have paragraphs in
+Makefile: keeping related stuff altogether.
+
+=cut

+

+
+Holds the factored actions. Tied to C<%dependencies>, i.e., filled

+

+
+=item <$suffix_rules>
+
+This maps the source extension for all suffix rules seen to
+a C<hash> whose keys are the possible output extensions.
+
+Note that this is transitively closed by construction:
+if we have
+ exists $suffix_rules{$ext1}{$ext2}
+ && exists $suffix_rules{$ext2}{$ext3}
+then we also have
+ exists $suffix_rules{$ext1}{$ext3}
+
+So it's easy to check whether C<.foo> can be transformed to
+C<.$(OBJEXT)> by checking whether
+C<$suffix_rules{'.foo'}{'.$(OBJEXT)'}> exists. This will work even if
+transforming C<.foo> to C<.$(OBJEXT)> involves a chain of several
+suffix rules.
+
+The value of C<$suffix_rules{$ext1}{$ext2}> is a pair
+C<[ $next_sfx, $dist ]> where C<$next_sfx> is target suffix
+for the next rule to use to reach C<$ext2>, and C<$dist> the
+distance to C<$ext2'>.
+
+The content of this variable should be updated via the

+
+This package provides support for Makefile variable definitions.
+
+An C<Automake::Variable> is a variable name associated to possibly
+many conditional definitions. These definitions are instances
+of C<Automake::VarDef>.
+
+Therefore obtaining the value of a variable under a given
+condition involves two lookups. One to look up the variable,
+and one to look up the conditional definition:
+
+ my $var = var $name;
+ if ($var)
+ {
+ my $def = $var->def ($cond);
+ if ($def)
+ {
+ return $def->value;
+ }
+ ...
+ }

+
+Split the value of the Automake::Variable C<$var> on space, and
+traverse its components recursively.
+
+If C<$cond_filter> is an C<Automake::Condition>, process any
+conditions which are true when C<$cond_filter> is true. Otherwise,
+process all conditions.
+
+We distinguish two kinds of items in the content of C<$var>.
+Terms that look like C<$(foo)> or C<${foo}> are subvariables
+and cause recursion. Other terms are assumed to be filenames.
+
+Each time a filename is encountered, C<&fun_item> is called with the
+following arguments:
+
+ ($var, -- the Automake::Variable we are currently
+ traversing
+ $val, -- the item (i.e., filename) to process
+ $cond, -- the Condition for the $var definition we are
+ examining (ignoring the recursion context)
+ $full_cond) -- the full Condition, taking into account
+ conditions inherited from parent variables
+ during recursion
+
+If C<inner_expand> is set, variable references occurring in filename
+(as in C<$(BASE).ext>) are expanded before the filename is passed to
+C<&fun_item>.
+
+If C<skip_ac_subst> is set, Autoconf @substitutions@ will be skipped,
+i.e., C<&fun_item> will never be called for them.
+
+C<&fun_item> may return a list of items, they will be passed to
+C<&fun_store> later on. Define C<&fun_item> or @<&fun_store> as
+C<undef> when they serve no purpose.
+
+Once all items of a variable have been processed, the result (of the
+calls to C<&fun_items>, or of recursive traversals of subvariables)
+are passed to C<&fun_collect>. C<&fun_collect> receives three
+arguments:
+
+ ($var, -- the variable being traversed
+ $parent_cond, -- the Condition inherited from parent
+ variables during recursion
+ @condlist) -- a list of [$cond, @results] pairs
+ where each $cond appear only once, and @result
+ are all the results for this condition.
+
+Typically you should do C<$cond->merge ($parent_cond)> to recompute
+the C<$full_cond> associated to C<@result>. C<&fun_collect> may
+return a list of items, that will be used as the result of
+C<Automake::Variable::traverse_recursively> (the top-level, or its
+recursive calls).

+
+Automake::Version - version comparison
+
+=head1 SYNOPSIS
+
+ use Automake::Version;
+
+ print "Version $version is older than required version $required\n"
+ if Automake::Version::check ($version, $required);
+
+=head1 DESCRIPTION
+
+This module provides support for comparing versions string
+as they are used in Automake.
+
+A version is a string that looks like
+C<MAJOR.MINOR[.MICRO][ALPHA][-FORK]> where C<MAJOR>, C<MINOR>, and
+C<MICRO> are digits, C<ALPHA> is a character, and C<FORK> any
+alphanumeric word.
+
+Usually, C<ALPHA> is used to label alpha releases or intermediate
+snapshots, C<FORK> is used for git branches or patched releases, and
+C<MICRO> is used for bug fixes releases on the C<MAJOR.MINOR> branch.
+
+For the purpose of ordering, C<1.4> is the same as C<1.4.0>, but
+C<1.4g> is the same as C<1.4.99g>. The C<FORK> identifier is ignored
+in the ordering, except when it looks like C<-pMINOR[ALPHA]>: some
+versions were labeled like C<1.4-p3a>, this is the same as an alpha
+release labeled C<1.4.3a>. Yes, it's horrible, but Automake did not
+support two-dot versions in the past.
+
+=head2 FUNCTIONS
+
+=over 4
+
+=item C<split ($version)>
+
+Split the string C<$version> into the corresponding C<(MAJOR, MINOR,
+MICRO, ALPHA, FORK)> tuple. For instance C<'1.4g'> would be split
+into C<(1, 4, 99, 'g', '')>. Return C<()> on error.

+ # Special case for versions like 1.4-p2a.

+ }
+ return ();
+}
+
+=item C<compare (\@LVERSION, \@RVERSION)>
+
+Compare two version tuples, as returned by C<split>.
+
+Return 1, 0, or -1, if C<LVERSION> is found to be respectively
+greater than, equal to, or less than C<RVERSION>.

+=item C<check($VERSION, $REQUIRED)>
+
+Handles the logic of requiring a version number in Automake.
+C<$VERSION> should be Automake's version, while C<$REQUIRED>
+is the version required by the user input.
+
+Return 0 if the required version is satisfied, 1 otherwise.

+
+This modules provide facility to format list of strings. It is

+C<"$eol\n$fill"> so that the length of each line never exceeds
+C<$max_len>.

+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+ The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works. By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users. We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors. You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+ <program> Copyright (C) <year> <name of author>
+ This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+ You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<http://www.gnu.org/licenses/>.
+
+ The GNU General Public License does not permit incorporating your program
+into proprietary programs. If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License. But first, please read
+<http://www.gnu.org/philosophy/why-not-lgpl.html>.

+
+Copyright (C) 1994-1996, 1999-2002, 2004-2012 Free Software Foundation,
+Inc.
+
+ Copying and distribution of this file, with or without modification,
+are permitted in any medium without royalty provided the copyright
+notice and this notice are preserved. This file is offered as-is,
+without warranty of any kind.
+
+Basic Installation
+==================
+
+ Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package. The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package. Some packages provide this
+`INSTALL' file but do not implement all of the features documented
+below. The lack of an optional feature in a given package is not
+necessarily a bug. More recommendations for GNU packages can be found
+in *note Makefile Conventions: (standards)Makefile Conventions.
+
+ The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation. It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions. Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+ It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring. Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+ If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release. If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+ The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'. You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+ The simplest way to compile this package is:
+
+ 1. `cd' to the directory containing the package's source code and type
+ `./configure' to configure the package for your system.
+
+ Running `configure' might take a while. While running, it prints
+ some messages telling which features it is checking for.
+
+ 2. Type `make' to compile the package.
+
+ 3. Optionally, type `make check' to run any self-tests that come with
+ the package, generally using the just-built uninstalled binaries.
+
+ 4. Type `make install' to install the programs and any data files and
+ documentation. When installing into a prefix owned by root, it is
+ recommended that the package be configured and built as a regular
+ user, and only the `make install' phase executed with root
+ privileges.
+
+ 5. Optionally, type `make installcheck' to repeat any self-tests, but
+ this time using the binaries in their final installed location.
+ This target does not install anything. Running this target as a
+ regular user, particularly if the prior `make install' required
+ root privileges, verifies that the installation completed
+ correctly.
+
+ 6. You can remove the program binaries and object files from the
+ source code directory by typing `make clean'. To also remove the
+ files that `configure' created (so you can compile the package for
+ a different kind of computer), type `make distclean'. There is
+ also a `make maintainer-clean' target, but that is intended mainly
+ for the package's developers. If you use it, you may have to get
+ all sorts of other programs in order to regenerate files that came
+ with the distribution.
+
+ 7. Often, you can also type `make uninstall' to remove the installed
+ files again. In practice, not all packages have tested that
+ uninstallation works correctly, even though it is required by the
+ GNU Coding Standards.
+
+ 8. Some packages, particularly those that use Automake, provide `make
+ distcheck', which can by used by developers to test that all other
+ targets like `make install' and `make uninstall' work correctly.
+ This target is generally not run by end users.
+
+Compilers and Options
+=====================
+
+ Some systems require unusual options for compilation or linking that
+the `configure' script does not know about. Run `./configure --help'
+for details on some of the pertinent environment variables.
+
+ You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment. Here
+is an example:
+
+ ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+ *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+ You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory. To do this, you can use GNU `make'. `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script. `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'. This
+is known as a "VPATH" build.
+
+ With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory. After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+ On MacOS X 10.5 and later systems, you can create libraries and
+executables that work on multiple system types--known as "fat" or
+"universal" binaries--by specifying multiple `-arch' options to the
+compiler but only a single `-arch' option to the preprocessor. Like
+this:
+
+ ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
+ CPP="gcc -E" CXXCPP="g++ -E"
+
+ This is not guaranteed to produce working output in all cases, you
+may have to build one architecture at a time and combine the results
+using the `lipo' tool if you have problems.
+
+Installation Names
+==================
+
+ By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc. You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX', where PREFIX must be an
+absolute file name.
+
+ You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files. If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+ In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files. Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them. In general, the
+default for these options is expressed in terms of `${prefix}', so that
+specifying just `--prefix' will affect all of the other directory
+specifications that were not explicitly provided.
+
+ The most portable way to affect installation locations is to pass the
+correct locations to `configure'; however, many packages provide one or
+both of the following shortcuts of passing variable assignments to the
+`make install' command line to change installation locations without
+having to reconfigure or recompile.
+
+ The first method involves providing an override variable for each
+affected directory. For example, `make install
+prefix=/alternate/directory' will choose an alternate location for all
+directory configuration variables that were expressed in terms of
+`${prefix}'. Any directories that were specified during `configure',
+but not in terms of `${prefix}', must each be overridden at install
+time for the entire installation to be relocated. The approach of
+makefile variable overrides for each directory variable is required by
+the GNU Coding Standards, and ideally causes no recompilation.
+However, some platforms have known limitations with the semantics of
+shared libraries that end up requiring recompilation when using this
+method, particularly noticeable in packages that use GNU Libtool.
+
+ The second method involves providing the `DESTDIR' variable. For
+example, `make install DESTDIR=/alternate/directory' will prepend
+`/alternate/directory' before all installation names. The approach of
+`DESTDIR' overrides is not required by the GNU Coding Standards, and
+does not work on platforms that have drive letters. On the other hand,
+it does better at avoiding recompilation issues, and works well even
+when some directory options were not specified in terms of `${prefix}'
+at `configure' time.
+
+Optional Features
+=================
+
+ If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+ Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System). The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+ For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+ Some packages offer the ability to configure how verbose the
+execution of `make' will be. For these packages, running `./configure
+--enable-silent-rules' sets the default to minimal output, which can be
+overridden with `make V=1'; while running `./configure
+--disable-silent-rules' sets the default to verbose, which can be
+overridden with `make V=0'.
+
+Particular systems
+==================
+
+ On HP-UX, the default C compiler is not ANSI C compatible. If GNU
+CC is not installed, it is recommended to use the following options in
+order to use an ANSI C compiler:
+
+ ./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
+
+and if that doesn't work, install pre-built binaries of GCC for HP-UX.
+
+ HP-UX `make' updates targets which have the same time stamps as
+their prerequisites, which makes it generally unusable when shipped
+generated files such as `configure' are involved. Use GNU `make'
+instead.
+
+ On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
+parse its `<wchar.h>' header file. The option `-nodtk' can be used as
+a workaround. If GNU CC is not installed, it is therefore recommended
+to try
+
+ ./configure CC="cc"
+
+and if that doesn't work, try
+
+ ./configure CC="cc -nodtk"
+
+ On Solaris, don't put `/usr/ucb' early in your `PATH'. This
+directory contains several dysfunctional programs; working variants of
+these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
+in your `PATH', put it _after_ `/usr/bin'.
+
+ On Haiku, software installed for all users goes in `/boot/common',
+not `/usr/local'. It is recommended to use the following options:
+
+ ./configure --prefix=/boot/common
+
+Specifying the System Type
+==========================
+
+ There may be some features `configure' cannot figure out
+automatically, but needs to determine by the type of machine the package
+will run on. Usually, assuming the package is built to be run on the
+_same_ architectures, `configure' can figure that out, but if it prints
+a message saying it cannot guess the machine type, give it the
+`--build=TYPE' option. TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+ CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+ OS
+ KERNEL-OS
+
+ See the file `config.sub' for the possible values of each field. If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+ If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+ If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+ If you want to set default values for `configure' scripts to share,
+you can create a site shell script called `config.site' that gives
+default values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists. Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+ Variables not defined in a site shell script can be set in the
+environment passed to `configure'. However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost. In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'. For example:
+
+ ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf limitation. Until the limitation is lifted, you can use
+this workaround:
+
+ CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+ `configure' recognizes the following options to control how it
+operates.
+
+`--help'
+`-h'
+ Print a summary of all of the options to `configure', and exit.
+
+`--help=short'
+`--help=recursive'
+ Print a summary of the options unique to this package's
+ `configure', and exit. The `short' variant lists options used
+ only in the top level, while the `recursive' variant lists options
+ also present in any nested packages.
+
+`--version'
+`-V'
+ Print the version of Autoconf used to generate the `configure'
+ script, and exit.
+
+`--cache-file=FILE'
+ Enable the cache: use and save the results of the tests in FILE,
+ traditionally `config.cache'. FILE defaults to `/dev/null' to
+ disable caching.
+
+`--config-cache'
+`-C'
+ Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+ Do not print messages saying which checks are being made. To
+ suppress all normal output, redirect it to `/dev/null' (any error
+ messages will still be shown).
+
+`--srcdir=DIR'
+ Look for the package's source code in directory DIR. Usually
+ `configure' can determine that directory automatically.
+
+`--prefix=DIR'
+ Use DIR as the installation prefix. *note Installation Names::
+ for more details, including other options available for fine-tuning
+ the installation locations.
+
+`--no-create'
+`-n'
+ Run the configure checks, but stop before creating any output
+ files.
+
+`configure' also accepts some other, not widely useful, options. Run
+`configure --help' for more details.

+## This file is read several times:
+## - once per *extension* (not per language) for generic compilation rules
+## - once for each file which requires specific flags.
+
+## Note it is on purpose we wrote "if %AMDEP%", since:
+##
+## - if deps are turned off, %AMDEP% is mapped onto FALSE, and therefore
+## the "if FALSE" chunk is removed (automake-time conditionals).
+##
+## - if deps are on, %AMDEP% is mapped onto AMDEP, and therefore
+## the "if AMDEP" chunk is prefix with @AMDEP_TRUE@ just like for any
+## other configure-time conditional.
+##
+## We do likewise for %FASTDEP%; this expands to an ordinary
+## configure-time conditional. %FASTDEP% is used to speed up the
+## common case of building a package with gcc 3.x. In this case we
+## can skip the use of depcomp and easily inline the dependency
+## tracking.
+
+## Verbosity of FASTDEP rules
+## --------------------------
+## (1) Some people want to see what happens during make. They think
+## @-commands are evil because hiding things hinders debugging.
+## (2) Other people want to see only the important commands--those that
+## may produce diagnostics, such as compiler invocations. They
+## do not care about build details such as dependency generation
+## (the if/then/else machinery in FASTDEP rules). Their point is
+## that it is hard to spot diagnostics in a verbose output.
+## (3) Other people want "make -s" to work as expected: silently.
+## This way they can spot any diagnostic really easily.
+##
+## The second point suggests we hide rules with @ and that we 'echo'
+## only the relevant parts. However this goes against the two others.
+## There are regular complaints about this on the mailing list, but
+## it's hard to please everybody. On April 2003, William Fulton (from
+## clan (3)) and Karl Berry (from clan (2)) agreed that folding the
+## compile rules so that they are output on a single line (instead of 5)
+## would be a good compromise. Actually we use two lines rather than one,
+## because this way %SOURCE% is always located at the end of the first
+## line and is therefore easier to spot. (We need an extra line when
+## depbase is used.)

+## Yet another hack to support SUN make.
+##
+## Let's assume 'foo' appears in DISTFILES and is not a built file.
+## When building with VPATH=$(srcdir), SUN make and OSF1/Tru64 will
+## rewrite 'foo' as '$(srcdir)/foo'. An attempt to install the file
+## with
+## cp $file $(distdir)/$file
+## will thus install $(srcdir)/foo as $(distdir)/$(srcdir)/foo
+## instead of $(distdir)/foo.
+##
+## So let's strip this leading $(srcdir)/ when it exists. (As far we
+## know, only SUN make and OSF1/Tru64 make add it.) Searching whether
+## the file is to be found in the source or build directory will be
+## done later.
+##
+## In case we are _not_ using SUN or OSF1/Tru64 make, how can we be sure
+## we are not stripping a legitimate filename that starts with the
+## same pattern as $(srcdir)?
+## Well, it can't happen without the Makefile author distributing
+## something out of the distribution (which is bad). As an example,
+## consider "EXTRA_DIST = ../bar". This is an issue if $srcdir is
+## '..', however getting this value for srcdir is impossible:
+## "EXTRA_DIST = ../bar" implies we are in a subdirectory (so '../bar'
+## is within the package), hence '$srcdir' is something like
+## '../../subdir'.
+##
+## There is more to say about files which are above the current directory,
+## like '../bar' in the previous example. The OSF1/Tru64 make

+##
+## There are some tricky cases where this rule will build a
+## config.hin which has the same timestamp as %STAMP%, in which case
+## ./config.status will not be rerun (meaning that users will use an
+## out-of-date config.h without knowing it). One situation where this
+## can occur is the following:
+## 1. the user updates some configure dependency (let's say foo.m4)
+## and runs 'make';
+## 2. the rebuild rules detect that a foo.m4 has changed,
+## run aclocal, autoconf, automake, and then run ./config.status.
+## (Note that autoheader hasn't been called yet, so ./config.status
+## outputs a config.h from an obsolete config.hin);
+## 3. once Makefile has been regenerated, make continues, and
+## discovers that config.h is a dependency of the 'all' rule.
+## Because config.h depends on stamp-h1, stamp-h1 depends on
+## config.hin, and config.hin depends on aclocal.m4, make runs
+## autoheader to rebuild config.hin.
+## Now make ought to call ./config.status once again to rebuild
+## config.h from the new config.hin, but if you have a sufficiently
+## fast box, steps 2 and 3 will occur within the same second: the
+## config.h/stamp-h1 generated from the outdated config.hin will have
+## the same mtime as the new config.hin. Hence make will think that
+## config.h is up to date.
+##
+## A solution is to erase %STAMP% here so that the %STAMP% rule
+## is always triggered after the this one.
+ rm -f %STAMP%
+## Autoheader has the bad habit of not changing the timestamp if
+## config.hin is unchanged, which breaks Make targets. Since what
+## must not changed gratuitously is config.h, which is already handled
+## by config.status, there is no reason to make things complex for
+## config.hin.

+
+Convert git log output to ChangeLog format. If present, any ARGS

+$ME, they may be preceded by '--'.
+
+OPTIONS:
+
+ --amend=FILE FILE maps from an SHA1 to perl code (i.e., s/old/new/) that
+ makes a change to SHA1's commit log text or metadata.
+ --append-dot append a dot to the first line of each commit message if
+ there is no other punctuation or blank at the end.
+ --no-cluster never cluster commit messages under the same date/author
+ header; the default is to cluster adjacent commit messages
+ if their headers are the same and neither commit message
+ contains multiple paragraphs.
+ --since=DATE convert only the logs since DATE;
+ the default is to convert all log entries.
+ --format=FMT set format string for commit subject and body;
+ see 'man git-log' for the list of format metacharacters;
+ the default is '%s%n%b%n'
+
+ --help display this help and exit
+ --version output version information and exit
+
+EXAMPLE:
+
+ $ME --since=2008-01-01 > ChangeLog
+ $ME -- -n 5 foo > last-5-commits-to-branch-foo
+
+SPECIAL SYNTAX:
+
+The following types of strings are interpreted specially when they appear
+at the beginning of a log message line. They are not copied to the output.
+
+ Copyright-paperwork-exempt: Yes
+ Append the "(tiny change)" notation to the usual "date name email"
+ ChangeLog header to mark a change that does not require a copyright
+ assignment.
+ Co-authored-by: Joe User <user\@example.com>
+ List the specified name and email address on a second
+ ChangeLog header, denoting a co-author.
+ Signed-off-by: Joe User <user\@example.com>
+ These lines are simply elided.
+
+In a FILE specified via --amend, comment lines (starting with "#") are ignored.
+FILE must consist of <SHA,CODE+> pairs where SHA is a 40-byte SHA1 (alone on
+a line) referring to a commit in the current project, and CODE refers to one
+or more consecutive lines of Perl code. Pairs must be separated by one or
+more blank line.
+
+Here is sample input for use with --amend=FILE, from coreutils:
+

+
+Sign all FILES, and process them at selected destinations according to CMD.
+<http://www.gnu.org/prep/maintain/html_node/Automated-FTP-Uploads.html>
+explains further.
+
+Commands:
+ --delete delete FILES from destination
+ --symlink create symbolic links
+ --rmsymlink remove symbolic links
+ -- treat the remaining arguments as files to upload
+
+Options:
+ --help print this help text and exit
+ --to DEST specify one destination for FILES
+ (multiple --to options are allowed)
+ --user NAME sign with key NAME
+ --symlink-regex[=EXPR] use sed script EXPR to compute symbolic link names
+ --dry-run do nothing, show what would have been done
+ --version output version information and exit
+
+If --symlink-regex is given without EXPR, then the link target name
+is created by replacing the version information with '-latest', e.g.:
+
+ foo-1.3.4.tar.gz -> foo-latest.tar.gz
+
+Recognized destinations are:
+ alpha.gnu.org:DIRECTORY
+ savannah.gnu.org:DIRECTORY
+ savannah.nongnu.org:DIRECTORY
+ ftp.gnu.org:DIRECTORY
+ build directive files and upload files by FTP
+ download.gnu.org.ua:{alpha|ftp}/DIRECTORY
+ build directive files and upload files by SFTP
+ [user@]host:DIRECTORY upload files with scp
+
+Options and commands are applied in order. If the file $conffile exists
+in the current working directory, its contents are prepended to the
+actual command line options. Use this to keep your defaults. Comments
+(#) and empty lines in $conffile are allowed.
+
+Examples:
+1. Upload foobar-1.0.tar.gz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz
+
+2. Upload foobar-1.0.tar.gz and foobar-1.0.tar.xz to ftp.gnu.org:
+ gnupload --to ftp.gnu.org:foobar foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+3. Same as above, and also create symbolic links to foobar-latest.tar.*:
+ gnupload --to ftp.gnu.org:foobar \\
+ --symlink-regex \\
+ foobar-1.0.tar.gz foobar-1.0.tar.xz
+
+4. Upload foobar-0.9.90.tar.gz to two sites:
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ foobar-0.9.90.tar.gz
+
+5. Delete oopsbar-0.9.91.tar.gz and upload foobar-0.9.91.tar.gz
+ (the -- terminates the list of files to delete):
+ gnupload --to alpha.gnu.org:foobar \\
+ --to sources.redhat.com:~ftp/pub/foobar \\
+ --delete oopsbar-0.9.91.tar.gz \\
+ -- foobar-0.9.91.tar.gz
+
+gnupload uses the ncftpput program to do the transfers; if you don't
+happen to have an ncftp package installed, the ncftpput-ftp script in
+the build-aux/ directory of the gnulib package
+(http://savannah.gnu.org/projects/gnulib) may serve as a replacement.

+% restriction. (This has been our intent since Texinfo was invented.)
+%
+% Please try the latest version of texinfo.tex before submitting bug
+% reports; you can get the latest version from:
+% http://www.gnu.org/software/texinfo/ (the Texinfo home page), or
+% ftp://tug.org/tex/texinfo.tex
+% (and all CTAN mirrors, see http://www.ctan.org).
+% The texinfo.tex in any given distribution could well be out

+%
+% Send bug reports to bug-texinfo@gnu.org. Please include including a
+% complete document in each bug report with which we can reproduce the
+% problem. Patches are, of course, greatly appreciated.
+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution. For a simple
+% manual foo.texi, however, you can get away with this:
+% tex foo.texi
+% texindex foo.??
+% tex foo.texi
+% tex foo.texi
+% dvips foo.dvi -o # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent. You can get the existing language-specific files from the
+% full Texinfo distribution.

+% Output a mark which sets \thischapter, \thissection and \thiscolor.

+%
+% A mark contains a subexpression of the \ifcase ... \fi construct.

+%
+% Another complication is to let the user choose whether \thischapter
+% (\thissection) refers to the chapter (section) in effect at the top
+% of a page, or that at the bottom of a page. The solution is
+% described on page 260 of The TeXbook. It involves outputting two

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble. Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+% @multitable @columnfractions .25 .3 .45
+% @item ...
+%
+% Numbers following @columnfractions are the percent of the total
+% current hsize to be used for each column. You may use as many
+% columns as desired.
+
+
+% Or use a template:
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item ...
+% using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+% @item first col stuff @tab second col stuff @tab third col
+% @item
+% first col stuff
+% @tab
+% second col stuff
+% @tab
+% third col
+% @item first col stuff @tab second col stuff
+% @tab Many paragraphs of text may be used in any column.
+%
+% They will wrap at the width determined by the template.
+% @item@tab@tab This will be in third column.
+% @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+% to baseline.
+% 0pt means it depends on current normal line spacing.

+
+# The arguments to this script should be names of files that contain
+# copyright statements to be updated. The copyright holder's name
+# defaults to "Free Software Foundation, Inc." but may be changed to
+# any other name by using the "UPDATE_COPYRIGHT_HOLDER" environment
+# variable.
+#
+# For example, you might wish to use the update-copyright target rule
+# in maint.mk from gnulib's maintainer-makefile module.
+#
+# Iff a copyright statement is recognized in a file and the final
+# year is not the current year, then the statement is updated for the
+# new year and it is reformatted to:
+#
+# 1. Fit within 72 columns.
+# 2. Convert 2-digit years to 4-digit years by prepending "19".
+# 3. Expand copyright year intervals. (See "Environment variables"
+# below.)
+#
+# A warning is printed for every file for which no copyright
+# statement is recognized.
+#
+# Each file's copyright statement must be formatted correctly in
+# order to be recognized. For example, each of these is fine:
+#
+# Copyright @copyright{} 1990-2005, 2007-2009 Free Software
+# Foundation, Inc.
+#
+# # Copyright (C) 1990-2005, 2007-2009 Free Software
+# # Foundation, Inc.
+#
+# /*
+# * Copyright © 90,2005,2007-2009
+# * Free Software Foundation, Inc.
+# */
+#
+# However, the following format is not recognized because the line
+# prefix changes after the first line:
+#
+# ## Copyright (C) 1990-2005, 2007-2009 Free Software
+# # Foundation, Inc.
+#
+# However, any correctly formatted copyright statement following
+# a non-matching copyright statements would be recognized.
+#
+# The exact conditions that a file's copyright statement must meet
+# to be recognized are:
+#
+# 1. It is the first copyright statement that meets all of the
+# following conditions. Subsequent copyright statements are
+# ignored.
+# 2. Its format is "Copyright (C)", then a list of copyright years,
+# and then the name of the copyright holder.
+# 3. The "(C)" takes one of the following forms or is omitted
+# entirely:
+#
+# A. (C)
+# B. (c)
+# C. @copyright{}
+# D. ©
+#
+# 4. The "Copyright" appears at the beginning of a line, except that it
+# may be prefixed by any sequence (e.g., a comment) of no more than
+# 5 characters -- including white space.
+# 5. Iff such a prefix is present, the same prefix appears at the
+# beginning of each remaining line within the FSF copyright
+# statement. There is one exception in order to support C-style
+# comments: if the first line's prefix contains nothing but
+# whitespace surrounding a "/*", then the prefix for all subsequent
+# lines is the same as the first line's prefix except with each of
+# "/" and possibly "*" replaced by a " ". The replacement of "*"
+# by " " is consistent throughout all subsequent lines.
+# 6. Blank lines, even if preceded by the prefix, do not appear
+# within the FSF copyright statement.
+# 7. Each copyright year is 2 or 4 digits, and years are separated by
+# commas or dashes. Whitespace may appear after commas.
+#
+# Environment variables:
+#
+# 1. If UPDATE_COPYRIGHT_FORCE=1, a recognized FSF copyright statement
+# is reformatted even if it does not need updating for the new
+# year. If unset or set to 0, only updated FSF copyright
+# statements are reformatted.
+# 2. If UPDATE_COPYRIGHT_USE_INTERVALS=1, every series of consecutive
+# copyright years (such as 90, 1991, 1992-2007, 2008) in a
+# reformatted FSF copyright statement is collapsed to a single
+# interval (such as 1990-2008). If unset or set to 0, all existing
+# copyright year intervals in a reformatted FSF copyright statement
+# are expanded instead.
+# If UPDATE_COPYRIGHT_USE_INTERVALS=2, convert a sequence with gaps
+# to the minimal containing range. For example, convert
+# 2000, 2004-2007, 2009 to 2000-2009.
+# 3. For testing purposes, you can set the assumed current year in
+# UPDATE_COPYRIGHT_YEAR.
+# 4. The default maximum line length for a copyright line is 72.
+# Set UPDATE_COPYRIGHT_MAX_LINE_LENGTH to use a different length.
+# 5. Set UPDATE_COPYRIGHT_HOLDER if the copyright holder is other
+# than "Free Software Foundation, Inc.".

+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a

+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+ * clean.am: here.
+
+2001-02-06 Akim Demaille <akim@epita.fr>
+
+ Monstro unsplitable patch.
+
+ The aim is to remove hard coded knowledge about clean targets from
+ automake.in, leaving them in the *.am files.
+ In addition to the mechanic needed to factor some dependencies, it
+ appears some rules (most notably distclean and maintainer-clean)
+ need factored actions. So first, be ready to catch factored
+ rules.
+
+ * automake.in (&file_contents): For the time being, use an extended
+ $RULE_PATTERN which is able to match any kind of rules, with or
+ without dependency, with or without actions.
+ Handle all the rules uniformly, storing in %actions the factored
+ actions.
+ (&flatten, &target_cmp): New.
+ (&handle_factored_dependencies): Output the %actions.
+ No longer special case `clean'.
+ Output the rules in alphabetical order, but keeping `.PHONY' last.
+
+ Now we must not use &push_phony_cleaners, which is doing all sort
+ of magic to push a bit of everything in all the clean targets.
+ The biggest problem being that, making a Cartesian product, it
+ requires many useless targets. The `*.am' file know better.
+ But first, register the new factored rules.
+
+ * automake.in (&initialize_per_input): Include clean, mostlyclean,
+ maintainer-clean, distclean and their `*-am' counterpart in
+ %dependencies.
+ Initialize %actions.
+ (get_object_extension, handle_texinfo, handle_tags, handle_multilib)
+ handle_dependencies, handle_subdirs, handle_configure, handle_clean)
+ (handle_emacs_lisp, handle_python): Don't play with
+ &push_phony_cleaners nor &depend and `clean'.
+ * texinfos.am, texi-vers.am, tags-clean.am:
+ * subdirs.am,python-clean.am, multilib.am, lisp-clean.am:
+ * libtool.am, kr-extra.am, depend.am, compile.am, clean.am:
+ * clean-kr.am, clean-hdr.am: Do it.
+ Whenever a target is empty, just remove it, it will no longer be
+ called.
+
+ There is still some magic about clean to hard code. But really,
+ that's the end of &do_one_clean_target.
+
+ * automake.in (&do_one_clean_target): Kaboom out.
+ (&handle_clean): Rewrite the magic code.
+ (&am_install_var): No longer use &push_phony_cleaners, nor depend
+ on `clean'.
+ (&push_phony_cleaners): Kaboom too.

+ Mimic Paul Eggert's changes to Autoconf.

+ uninstall rules. This fixes installation of nobase_ files in
+ VPATH setups with Sun and OSF1/Tru64 Make.
+ * lib/am/libs.am, lib/am/ltlib.am: Include inst-vars.am, and use
+ $(am__strip_dir) to simplify install and uninstall rules.

+ Report from Harlan Stenn.
+
+2004-01-03 Alexandre Duret-Lutz <adl@gnu.org>
+
+ * automake.in (scan_texinfo_file): Do not compare $outfile to ''
+ as $outfile might not be defined at all.
+
+ * lib/Automake/Variable.pm (define): Rework the way we check
+ Automake variable definition. Ensure consistent :=/+=/=

+ Adjust.
+ Suggested by Tom Tromey.
+
+ Do not output .lo rules for programs and static libraries objects,
+ and do not output .o/.obj rules for libtool libraries. This is
+ about explicit rules only, not inference rules.
+ * automake.in (handle_single_transform_list): Rename as ...
+ (handle_single_transform): ... this. Take a single file
+ to transform (it was only called this way) and accept a new
+ %transform argument. Fill %lang_specific_files with list
+ references instead of strings, and append %transform to each
+ of these lists.
+ (define_objects_from_sources, handle_source_transform):
+ Take a %transform argument, and forward it to &handle_single_transform.
+ (handle_languages): Adjust to the new format of
+ %lang_specific_files, and honor its %transform part.
+ (handle_programs, handle_libraries, handle_ltlibraries): Override
+ %NONLIBTOOL% and %LIBTOOL% while calling handle_source_transform.
+ (make_paragraphs): Define %NONLIBTOOL% by default. Make sure
+ %transform settings override global settings.
+ * lib/am/depend2.am (%OBJ%, %OBJOBJ%): Define only if %NONLIBTOOL%.
+ * tests/libtool3.test: Augment to check Makefile.ins for unneeded
+ rules.
+ Suggested by Thomas Fitzsimmons.
+
+ * automake.in, aclocal.in: Bump copyright years.

+ (dist-gzip, dist-bzip2, dist-lzma, dist-xz, dist-tarZ)
+ (dist-shar, dist-zip): Use $(am__post_remove_distdir).

+
+ Fix race condition in werror2.test due to sanity sleep change.

+ * tests/subdir8.test: Likewise.
+
+ Improve description of the various *LINK variables.

+ (How the Linker is Chosen): Document how a per-target _LINK
+ variable and per-target link flags override linker selection.
+ * THANKS: Update.
+ Report by Dave Korn against gcc/libstdc++-v3.
+
+ Allow variable override of, rather than by, silent variables.
+ When overriding variables, check the VAR_SILENT status of the

+ of silent variables (these do not hit ordering bugs in the
+ automake output), but there is no use case for doing so the

+ annotated AM_SUBST_NOTMAKE in configure.ac.
+ * lib/Automake/Variable.pm (_check_ambiguous_condition): Check

+ * tests/Makefile.am: Update.
+ Spotted originally in binutils/bfd.
+
+ Fix `make clean check' for the Automake package.
+ * lib/Automake/Makefile.am (SUBDIRS): Add `.' before `tests',
+ so that Config.pm is built first.
+
+ Fix in-tree `recheck' after failed test that runs `check'.
+ If a test like pr401b-p.test fails for some reason, a `make
+ recheck' would cause another reason for failure because it sets
+ AM_MAKEFLAGS which gets propagated into the test and causes its
+ `make check' to fail.
+ * tests/defs.in: Also unset AM_MAKEFLAGS.
+
+2009-10-11 Stefano Lattarini <stefano.lattarini@gmail.com>

+ * tests/defs.in: Unset variable `TEST_LOG_COMPILER'.
+
+2009-10-07 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Testsuite: do not use `chmod -R' when cleaning up.
+ * tests/Makefile.am (clean-local-check): Do not use `chmod -R' on
+ the test directories, as that may change or try to change the mode
+ of installed files: the test directory may contain symlinks to
+ ltmain.sh files from a Libtool installation, and Solaris `chmod -R'
+ touches symlink targets. Instead, use the cleanup strategy used
+ in distdir.am (which is also employed in tests/defs.in).

+
+2009-10-01 Stefano Lattarini <stefano.lattarini@gmail.com> (tiny change)
+
+ Fix recommended way to run automake's test scripts with Zsh.
+ * tests/README (Supported shells): Changed the recommended way

+ python: do not install in system directories on Darwin 9.
+ On Darwin 9, get_python_lib returns a path below `/Library/Python'

+ * lib/Automake/Location.pm (serialize, deserialize): New
+ functions. They allows to serialize a Location in an array, and
+ to restore a Location from a thread queue. The API is
+ unsymmetric (array vs. queue) because enqueuing data needs to
+ happen atomically.
+
+ Parallel automake: ordered output messages.
+ * lib/Automake/Channels.pm (%_default_options): New options
+ `ordered' default enabled, `queue', default zero (no queue),
+ `queue_key' default undefined.
+ (_merge_options): Ensure `ordered' channels cannot have fatal
+ messages or backtrace output.

+ * automake.in (QUEUE_MESSAGE): New global constant, used as

+ ordered, using the new Channels.pm functions.
+ * tests/parallel-am.test: Also check for ordered output (in the

+ * automake.in (require_file_internal): Instead of resetting the

+ using set_dir_cache_file.
+
+ No uniquifying for fatal, prog_error, and verbose messages.
+ There is no point in dropping critical messages, even if they

+ * tests/ltorder.test: Add program, to expose this.
+
+ Do not reorder nobase ltlib installation.
+ This patch changes back the order of installation of nobase

+ It does not fix the issue of strict dependency ordering, as

+
+ Fix multi-file installation for files in srcdir.
+ For files that can live in the build tree or the source tree,
+ we have to expect that prepending `$(srcdir)/' to each name
+ will let the install command line exceed length limitations.
+ Thus use a new macro, $(am__base_list), to install in chunks
+ of 40 files, similar to what we do for nobase_* files. There,
+ lower the limit to 40, too.
+ * lib/am/inst-vars.am (am__install_max): Lower to 40.
+ (am__base_list): New macro.
+ * lib/am/data.am (install-%DIR%%PRIMARY%) [%?BASE%]: Use it.
+ * lib/am/texinfos.am (install-dvi-am, install-html-am)
+ (install-info-am, install-pdf-am, install-ps-am): Likewise.

+ Use `Exit' instead of `exit' in test suite.
+ Cater to Bourne shells like Solaris sh that do not pass the
+ `exit' argument as status to the cleanup trap.
+ * Makefile.am (maintainer-check): Check that here-documents
+ use only `END' or `EOF' as delimiter in the test suite.
+ Check that, outside of here-documents, the tests do not use
+ `exit' with an argument, but use `Exit' instead.
+ * tests/defs.in (Exit): New function. Use it throughout,
+ starting with the introduction of the exit trap.

+
+ For all possibly-relative subdirs, use $(am__cd).
+ Up to now, $(am__cd) was only used within backquotes, to avoid

+ * Makefile.am (maintainer-check): Fix current check for

+ * tests/nobase-python.test: Listing a dependency to be found
+ via VPATH search explicitly, without the path, as a target,
+ will turn off VPATH search for FreeBSD make. So move the

+ * tests/mmode.test: New test.
+ * tests/Makefile.am: Adjust.
+ * NEWS: Update.
+ Suggestion by Vincent Lefevre.

+
+2008-08-19 Reuben Thomas <rrt@sc3d.org> (tiny patch)

+
+ * lib/gnupload: Provide also a simple example.
+
+2008-06-25 Thien-Thi Nguyen <ttn@gnuvola.org>

+
+2008-06-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

+ depfile *.Tpo to its final destination *.Po.
+
+2008-06-18 Rafael Espindola <espindola@google.com>

+
+ * lib/am/inst-vars.am (am__install_max): New variable.

+
+ Fix conditional rules competing with config.status rules.
+ * automake.in (handle_configure): Teach targets about the
+ conditional config.status rule.
+ * tests/cond39.test: Adjust test to expose this.
+
+ For AC_CONFIG_LINKS(X,X), do not clean X in a non-VPATH build.
+ * automake.in (rewrite_inputs_into_dependencies): Do distribute
+ inputs where input and output name are equal. This relies on
+ the assumption that it only happens with AC_CONFIG_LINKS.
+ (handle_configure) <CONFIG_CLEAN_VPATH_FILES>: New variable, for
+ links where source and dest are equal.
+ * lib/am/clean.am (distclean-generic): Remove, if build tree not

+ Report from Bas Wijnen.
+ * tests/amopt.test: New test.
+ * tests/Makefile.am (TESTS): Add it.
+
+ * aclocal.in (install_file): Cannot use /dev/null while diffing
+ new files, because Tru64's diff do not handle /dev/null. So
+ create an empty destination file before running diff on a new
+ file, and erase it afterward. Fall back to using /dev/null only
+ if we cannot create this file.
+ Report and initial patch from Ralf Wildenhues.
+ (unlink_tmp): New function.
+ * test/acloca18.test: Make sure the empty file has been erased.
+
+2006-08-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
+
+ * automake.in (handle_LIBOBJS_or_ALLOCA): With subdir-objects,
+ do not prefix `$(top_builddir)/' aka `./' to nonempty LIBOBJDIR,
+ to help BSD Make find the files also in a VPATH build.
+ Also return the same path, possibly prefixed, for correct
+ depdir computation.
+ * tests/pr401.test: Update to expose wrong depdir computation.
+ Rewrite to not use the same file name for library object and
+ main program.
+ * tests/pr401b.test, tests/pr401c.test: Likewise.
+
+2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * lib/install-sh: Don't incorrectly claim that this implementation
+ can install only one file at a time.
+ (doit_exec): New var, for using 'exec' if possible, to save a process.
+ (test_mode, intermediate_mode): Remove.
+ (mode): Check for IFS or globbing characters in mode, since they might
+ cause weird behavior with the other changes below. All later uses
+ of '"$mode"' changed to '$mode', since the ""s no longer matter.
+ Use octal modes if the invoker specifies an octal mode, and use
+ octal umask values if 'umask' outputs octal values; this is more
+ likely to work with older operating systems since Automake uses
+ octal modes, and also works around a bug with HP-UX 11.23
+ 'mkdir -p -m u=rwx,g=rx,o=rx,u+wx' reported by Ralf Wildenhues in
+ <http://lists.gnu.org/archive/html/bug-automake/2006-06/msg00024.html>.
+ (cp_umask, mkdir_umask): New variables, to avoid
+ temporarily creating files or directories with too-permissive modes.
+ (mkdir_mode): Use the FreeBSD 'install' method for computing modes of
+ intermediate directories; this is safer.
+ (posix_mkdir): Also test mkdir -p -m ... by making a directory in
+ /tmp and checking the resulting mode with 'ls', to catch a bug in
+ HP-UX 11.23 and IRIX 6.5 mkdir reported by Ralf in the same message.
+ Use ':' for true, not 'true'; this is a bit faster on
+ traditional implementations.

+
+2006-06-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
+
+ * m4/depend.m4 (_AM_DEPENDENCIES): The IRIX MIPSpro compiler

+
+ * configure.ac (ACLOCAL): Use `-I m4' to match `./bootstrap'

+
+ * tests/gettext.test: AM_PROG_GETTEXT of gettext >= 0.14.3

+

+
+ * lib/am/java.am (class%DIR%.stamp): Do not assume `$?' has

+
+ * tests/overrid.test: Change all regexes for warning messages to

+
+ * tests/java.test: `configure' uses a trap, so use `(exit 77);

+
+ * tests/mkinst3.test: Fix `mkdir' wrapper to not be confused

+
+ * lib/depcomp (ia64hp): Rename dependency style to..

+
+2005-11-01 Stepan Kasal <kasal@ucw.cz>
+

+ process.
+ * tests/instspc.test: The "*" test is now fixed.
+
+2005-09-13 Stepan Kasal <kasal@ucw.cz>

+
+ * lib/Automake/Variable.pm (require_variables): Mention aclocal's

+2005-07-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * tests/instspc.test: Major rewrite to test for many other
+ problematic file names, e.g., '$', '"', '('. Automake and
+ Autoconf can't handle many of them, so do not report a failure
+ if the usual candidates show up.
+
+2005-07-19 Stepan Kasal <kasal@ucw.cz>
+
+ * Makefile.am (automake, aclocal): Merge the rules.
+
+2005-07-10 Alexandre Duret-Lutz <adl@gnu.org>

+
+2005-07-09 Alexandre Duret-Lutz <adl@gnu.org>
+

+
+2005-06-24 Alexandre Duret-Lutz <adl@gnu.org>
+
+ * lib/Automake/Variable.pm (define, _new): Remember the helper
+ variable created for the last conditional += on each variable, and
+ only append further += in the same condition to this last helper
+ variable, not to older helper variables. This way the order of
+ the items appended to the variable is preserved.
+ * tests/cond21.test: Adjust.
+ * tests/cond38.test: New file.

+
+ * tests/aclocal5.test: Adjust to recent CVS Autoconf changes.
+
+ * automake.in (handle_footer): Do not output an unformatted

+
+ docs: "aclocal --install -I /abs/dir" actually copies files
+
+ This change is for automake bug#8407.
+
+ In the past, there had been some debate and confusion about
+ whether "aclocal --install" should copy third-party .m4 files
+ in the first directory passed to the `-I' option even when
+ such directory was given as an absolute path, or whether it
+ was better to do so only for directories specified with a
+ relative path.
+
+ The rationale for this latter behaviour was that, before the
+ existence of the `ACLOCAL_PATH' variable, the only way (a poor
+ way, I might add) for a common user to extend the search path
+ of a system-wide installation of aclocal was to export something
+ like ACLOCAL="aclocal -I /my/extra/macros" in the environment.
+ Today, the correct way to proceed is undoubtedly through the
+ use of ACLOCAL_PATH, so we can settle the question once and for
+ all, and start verifying the correct behaviour of `-I' with a
+ new test.
+
+ * tests/aclocal-install-absdir.test: New test.

+
+ docs: fix node names for automake and aclocal invocations
+
+ With the older node names, an "info automake" command issued
+ from the command line would have opened the node about the
+ invocation of the automake program, rather than the Top node
+ of the automake documentation. To invoke the Top node, one
+ had to issue the command "info Automake" instead (note the
+ different capitalization). This was suboptimal, and certainly
+ confusing.
+
+ With this change, "info automake" will open the Top node of the
+ automake documentation; to access the nodes about the invocation
+ of the automake and aclocal program, one has now to issue "info
+ automake-invocation" and "info aclocal-invocation" respectively.
+
+ This change fixes automake bug#8071.
+
+ See also commits `v2.61a-22-ge9215d1' and `v2.61a-72-g8c07b48' in

+
+ silent-rules: fallback for makes without nested vars
+
+ This fixes two problems reported for Automake (Bug#9928, Bug#10237)
+ and is in response to a bug report for building coreutils on HP
+ NonStop OS (Bug#10234). The problem is that HP NonStop 'make'
+ treats a line like "AM_V_CC = $(am__v_CC_$(V))" as one that
+ expands a macro with the funny name am__v_CC_$(V instead of the
+ desired name am__v_CC_1 or am__v_CC_0, and since the funny macro
+ is not defined the line is equivalent to "AM_V_CC = )"; this
+ inserts a stray ")" when $(AM_V_CC) is used, which eventually
+ causes 'make' to fail.
+
+ The basic idea is that instead of generating Makefile.in lines like
+ "AM_V_CC = $(am__v_CC_$(V))", we generate
+ "AM_V_CC = $(am__v_CC_@AM_V@)". We then AC_SUBST $(V) for @AM_V@
+ in the usual case where `make' supports nested variables,
+ and substitute 1 (or 0) otherwise. Similarly for usages like
+ $(am__v_CC_$(AM_DEFAULT_VERBOSITY)).
+
+ With this change, make implementations that doesn't grasp nested
+ variable expansions will still be able to run Makefiles generated
+ using the silent-rules option. They won't allow the user to
+ override the make verbosity at runtime through redefinition of
+ $(V) (as in "make V=0"); but this is still an improvement over not
+ being able to work at all.
+
+ * NEWS: Document this.
+ * automake.in (define_verbose_var): When defining the variables,
+ use @AM_V@ rather than $(V), and use @AM_DEFAULT_V@ rather than
+ $(AM_DEFAULT_VERBOSITY).
+ * doc/automake.texi (Automake silent-rules Option): Explain new system.
+ * m4/silent.m4 (AM_SILENT_RULES): Check whether `make' supports

+ * tests/gettext-macros.test (configure.in): Add calls to
+ AC_INIT and AC_PROG_CC, to avoid a spurious failure in the

+
+ tests: fix handling of gettext macros requirement
+
+ The code introduced in the earlier change `v1.11-581-gb7d67d5'
+ and aimed at automatically fetching all the .m4 files provided by
+ gettext has proven inadequate, since it hasn't managed to truly
+ and always get *all* the required .m4 files. For example, it has
+ failed to fetch the file `intldir.m4' (present in gettext 0.18.1,
+ and where the macro `AM_GNU_GETTEXT_INTL_SUBDIR' is defined),
+ which in turn has caused spurious SKIPs of at least the test
+ `gettext3.test'.
+
+ The reason for this debacle is that autopoint looks at the version
+ specified in AM_GNU_GETTEXT_VERSION to decide which version of the
+ gettext infrastructure to bring in; since we were unconditionally
+ specifying the older 0.10.35 version, the newer `.m4' files weren't
+ brought in.
+
+ * tests/gettext-macros.test: In AM_GNU_GETTEXT_VERSION, instead
+ of unconditionally specifying the older 0.10.35 version, specify
+ the version of the available `gettextize' or `autopoint' program,
+ dynamically extracted with the help of ...
+ (extract_program_version):... this new function, and saved ...
+ ($autopoint_version): ... in this new variable.

+ Originally, I myself had insisted on adding those "FIXME" comments

+ I did that with the expectation that we could have easily and soon
+ added a whitelisting capability to our maintainer-specific syntax

+ tests: better handling of gettext and libtool requirements
+
+ This change fixes automake bug#9807.
+
+ Before this change, the automake testsuite only looked for the
+ `.m4' files containing libtool and gettext macros definitions in
+ the directory `${prefix}/share/aclocal' (and in the directories
+ specified by the `dirlist' file in there, if any), where ${prefix}
+ was the configure-time automake installation prefix (defaulting
+ to `/usr/local').
+
+ This approach had various shortcomings and disadvantages. Let's
+ briefly describe the three major ones.
+
+ First, on most GNU/Linux systems, a libtool or gettext installed
+ from distro-provided packages (e.g., by dpkg on Debian/Ubuntu, or
+ by rmp on RedHat/Fedora) would have `/usr', not `/usr/local', as
+ its ${prefix}; so, trying to run the automake testsuite with a
+ simple "./configure && make && make check" would have failed to
+ execute the libtool and gettext tests on most GNU/Linux distros.
+ It's true that it was quite easy to work around this issue, by
+ creating a proper `/usr/local/share/aclocal/dirlist' file with
+ an entry pointing to `/usr/share/aclocal' (a workaround in fact
+ used by most automake developers); but the typical user wasn't
+ aware of the necessity of this trick, so the libtool and gettext
+ tests was usually skipped on testsuite runs "in the wild", thus
+ needlessly reducing coverage.
+
+ Second, the older testsuite behaviour made more difficult for
+ the developers to run the testsuite with non-default libtool or
+ gettext. For example, assume the developer is working on a system
+ that has a default libtool version 1.5 installed in the /usr/local
+ hierarchy; to improve coverage, the developer installs also a more
+ modern libtool version, say 2.4, in its home directory, let's say
+ in ~/libtool-2.4; he then tries to run the automake testsuite with
+ this more modern libtool by doing an (apparently) simple:
+ $ PATH=$HOME/libtool-2.4:$PATH make check
+ But the automake testsuite would still look for libtool macros in
+ /usr/local/share/aclocal, not in ~/libtool-2.4/share/aclocal, so
+ the wrong version of the macros would be picked up, and the tests
+ would either fail spuriously or (which would be worse) pass without
+ truly covering the libtool version the developers was thinking to
+ be testing with.
+ Worse again, the automake testsuite would *unconditionally* look
+ for libtool macros in /usr/local/share/aclocal, so even something
+ like:
+ $ export ACLOCAL_PATH=$HOME/libtool-2.4/share/aclocal
+ $ PATH=$HOME/libtool-2.4:$PATH make check
+ wouldn't work.
+
+ Third and last, during a "make distcheck", automake is configured
+ with a ${prefix} pointing to a proper subdirectory of the build
+ directory (usually `pwd`/_inst), which gets created on-the-fly;
+ in this case, with the old approach, the automake testsuite never
+ found the libtool and gettext macro files, ans so the libtool and
+ gettext tests was *always* skipped in a "make distcheck".
+

+ help of the `libtoolize' script) for libtool macro files required

+ tests: report useful system information in 'test-suite.log'
+ It has already happened various times that a user has run the
+ automake testsuite, experienced a failure, read the messages
+ telling him "See tests/test-suite.log" and "Please report to
+ bug-automake@gnu.org", and done exactly that -- sending us only
+ the contents of `tests/test-suite.log', which are usually not
+ enough to start debugging the reported failure. So we have to
+ ask him for more details, and usually also for the `config.log'
+ file generated by configure. It's time to fix this recurring
+ feedback inefficiency. We do so by creating a dummy test case
+ that takes care of copying the contents of `config.log', plus
+ other useful system information, in the final `test-suite.log'.
+ * tests/get-sysconf.test: New test, gathering system information

+ devel: help in comparing Makefile.in from different commits
+ Now that the generated Makefile.in, configure and aclocal.m4 files
+ are no longer committed in Automake's git repository, a simple
+ "git diff" or "git log" no longer shows if and how a change in
+ Automake results in changes to the Makefile.in files and/or
+ configure script of its own build system. Still, the ability to
+ peek so easily at such differences has proved itself quite useful
+ in the past, often revealing inconsistencies and blunders, and
+ sometimes even bugs; so it would be a pity to lose that altogether.
+ With this change, we add a new maintainer recipe that re-introduces
+ much of that capability, by generating and comparing on the fly the
+ Makefile.in, configure and aclocal.m4 derived from two arbitrary

+ repo: don't commit generated files in the git repository anymore
+ It has been quite some time since autoconf and libtool have stopped

+ with no significant ill effects we're aware of. It's true that the
+ autoconf bootstrap process has now the minor annoyance that a
+ pre-installed autoconf is required to complete it; but luckily
+ automake will not have a similar annoyance, since our bootstrap
+ script take care, through some hoops, to use the very automake and
+ aclocal versions from the current git checkout to generate the
+ required aclocal.m4 and Makefile.in files. In fact, this has been
+ a necessity also in the past, because automake has been known to
+ use in its own build system new development features that hadn't
+ been present in any previously released automake distribution.
+ * .gitignore: Ignore configure, aclocal.m4, and all the
+ Makefile.in files.
+ * configure.ac (AC_PREREQ): New macro call, to require the

+ Also, it's worth noting that the main purpose of the `missing'
+ script is to allow a non-developer to build the package in the

+
+ dist-xz, dist-bzip2: don't hard-code -9, honor envvar settings
+ Before the present change, automake-generated `dist-xz' rule used
+ a hard-coded `xz -9'. That was a problem because on this front,
+ xz differs from gzip and bzip2. While the latter two don't incur
+ any run-time decompression penalty for using a higher compression
+ level, specifying -9 with xz imposes a potentially fatal virtual
+ memory requirement on any client that wants to decompress your
+ tar.xz file.
+ People have complained that a tarball compressed with -9 cannot
+ be uncompressed in a low-memory environment (wrt-based embedded).
+ Hence, instead of defaulting to -9, which is useful only for very
+ large tarballs, it defaults to -e (equivalent to -6e). This
+ limits the default memory requirements imposed on decompressors,
+ yet still gives very good compression ratios.
+ * lib/am/distdir.am (dist-xz): Do not hard-code xz's -9: that made
+ it impossible to override. Actually don't default to -9, either,
+ since that induced inordinately large virtual memory usage when
+ merely decompressing. Instead, use its XZ_OPT envvar, defaulting
+ to -e if not defined. Suggested by Lasse Collin.
+ (dist-bzip2): Similarly, do not hard-code -9, but do continue to
+ use -9 by default. Honor the BZIP2 envvar.

+
+ tests: fix spurious failures due to missing 'yywrap()' function
+
+ The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
+ the "lex library" expected to provide a `yywrap' function (function
+ which is required to link most lex-generated programs). On the
+ contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
+ fail, configure declares that no lex library is needed, and simply
+ proceeds with the configuration process -- only for the build to
+ possibly fail later, at make time.
+
+ This behaviour is intended; the Autoconf manual reads:
+ ``You are encouraged to use Flex in your sources, since it is
+ both more pleasant to use than plain Lex and the C source it
+ produces is portable. In order to ensure portability, however,
+ you must either provide a function `yywrap' or, if you don't use
+ it (e.g., your scanner has no `#include'-like feature), simply
+ include a `%noyywrap' statement in the scanner's source.''
+
+ This AC_PROG_LEX behaviour is causing some spurious failures of
+ the Automake testsuite in environments which lack a proper library
+ providing `yywrap' (this happens for example on Fedora-based
+ systems). The proper workaround is to simply provide a fall-back
+ implementation of `yywrap' in our lexers.
+
+ See also partially-overlapping commit `v1.11-871-geb147a1' (from
+ the 'testsuite-work' branch), which was motivated by similar
+ spurious failures experienced when cross-compiling.

+ * tests/defs.in: Unset variables DMAKE_CHILD, DMAKE_DEF_PRINTED

+ tests: fix spurious failures w.r.t. parallel make and colorization
+ * tests/color2.test: Skip the test if the $MAKE program fails to

+ Solaris dmake, that redirect the output of recipes to temporary
+ files or pipes when run in parallel mode. Since we are at it,
+ simplify the detection of a working `expect' program, and throw
+ in other minor simplifications.

+ info: allow user to inhibit creation/update of '${infodir}/dir'
+ With this change, we allow the user to request the install-info
+ rules not to update the `${infodir}/dir' file, by setting the
+ environment variable `AM_UPDATE_INFO_DIR' to the value "no".
+ This is especially useful to distro packagers, and is a definite
+ improvement over our previous hack of looking whether the
+ `install-info' program was the Debian or GNU version -- hack
+ which had been silently broken with recent versions of debian

+ tests: fix spurious failures due to missing 'yywrap()' function
+
+ The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
+ the "lex library" expected to provide a `yywrap' function (function
+ which is required to link most lex-generated programs). On the
+ contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
+ fail, configure declares that no lex library is needed, and simply
+ proceeds with the configuration process -- only for the build to
+ possibly fail later, at make time.
+
+ This behaviour is intended; the Autoconf manual reads:
+ ``You are encouraged to use Flex in your sources, since it is
+ both more pleasant to use than plain Lex and the C source it
+ produces is portable. In order to ensure portability, however,
+ you must either provide a function `yywrap' or, if you don't use
+ it (e.g., your scanner has no `#include'-like feature), simply
+ include a `%noyywrap' statement in the scanner's source.''
+
+ This AC_PROG_LEX behaviour is causing some spurious failures of
+ the Automake testsuite in environments which lack a proper library
+ providing `yywrap' (this happens for example on Fedora-based
+ systems). The proper workaround is to simply provide a fall-back
+ implementation of `yywrap' in our lexers.
+
+ See also partially-overlapping commit `v1.11-871-geb147a1' (from
+ the 'testsuite-work' branch), which was motivated by similar
+ spurious failures experienced when cross-compiling.

+ dist: separate auxiliary file instantiation from DIST_COMMON update
+ This change simplifies the automake internals dealing with the
+ checking, copying and distributing of required auxiliary files.
+ With this change, a required auxiliary file is *unconditionally*
+ added to the contents of the DIST_COMMON variable in the generated
+ Makefile.in, before checking whether it exists, or trying to copy
+ it (if `--add-missing' is in use). This shouldn't be a problem,
+ since if the checking or copying of the file fails, automake will
+ bail out, the Makefile.in won't be created, and thus its content
+ will not matter. OK, this is not completely true when threaded
+ automake is in use, but then, such a situation was also possible
+ before this patch, so no regression here, which is enough for us.
+ This change is the first of a series of steps aimed at fixing
+ the regression introduced in threaded automake usage by commit

+
+ dist: simplify automake code accordingly to the previous changes
+ After the previous change `v1.11-1219-g326ecba', every Makefile.am
+ requiring a file in the "config auxdir" will cause it to be listed
+ in the DIST_COMMON variable of the corresponding generated
+ Makefile.in, not only of the top-level Makefile.in. Thus we don't
+ need to worry anymore about trying to distribute files in the
+ config auxdir from the top-level Makefile or the Makefile in
+ config auxdir (if any). This allows us to carry out some useful
+ simplifications in the automake script.
+ This will however cause some changes in the generated Makefile;
+ for example, if the `PROGRAMS' primary is used only in a subdir
+ Makefile.am, the `depcomp' script will be distributed only by
+ `subdir/Makefile', not by the top-level Makefile. This change
+ can be seen as an internal detail though, and definitely warranted
+ by the nice simplifications the current commit provides.

+
+ dist: auxiliary files can be distributed from subdir Makefiles
+ With this change, we make it possible for a subdir Makefile.am
+ to distribute files in the config auxdir; while this means that
+ some files might be copied multiple times, it simplify some logic
+ in the automake script, and fix at least one important bug. In
+ fact, before this change, the auxiliary script `test-driver' was
+ not being distributed as expected when TESTS was defined only in
+ a subdir Makefile (which is a pretty common setup indeed). Now
+ this does not happen anymore: so the present change fixes automake
+ bug#9546.
+ Another welcome collateral effect is that `dist-auxfile-2.test'
+ now passes.
+ OTOH, the present changes *breaks threaded automake*. The reason
+ is that automake needs to serialize file installations spawned
+ by `--add-missing' (this isn't for cosmetic reasons, but is
+ really needed to avoid possible race conditions and botched output
+ files). Currently the code that installs required files is
+ intertwined with the code that declares the DIST_COMMON variables;
+ so, upon de-serialization, the definition of DIST_COMMON might get
+ emitted in the wrong Makefile.in.
+ Some follow-up refactoring in automake will soon take care of
+ remedying this situation. For the moment, we just declare some
+ "parallel-am" tests as xfailing.
+ * automake.in (maybe_push_required_file): Add ad-hoc handling for
+ the case where the directory part of the required file is different
+ from the subdir where the current Makefile.am resides, but is equal
+ to the "config-aux directory" ($config_auxdir). This is needed to

+ After previous commit `v1.11-1424-g27a399a', some workarounds for

+ started causing XPASS results on Solaris.
+ * tests/tap-signal.tap: Remove unneeded workarounds for Solaris 10
+ /bin/sh. Some related minor code reorganizations.

+ aclocal: more granularity in acdir overriding
+ Before this change, using the `--acdir' option caused aclocal to
+ redefine both the directory of automake-provided m4 macros and the
+ directory of third-party system-wide m4 macros. With this change,
+ we deprecate the `--acdir' aclocal option, and introduce two new
+ options `--automake-acdir' and `--system-acdir', to allow for more
+ granularity.
+ * aclocal.in (@automake_includes, @system_includes,
+ @user_includes): Fix and extend comments.
+ (usage): Update.
+ (handle_acdir_option): New function.
+ (parse_arguments): Recognize new options `--system-acdir' and
+ `automake-acdir', and handle `--acdir' using the new function
+ above. Simplify logic by assuming that the directory of
+ third-party system-wide m4 files always exists.
+ * tests/aclocal.in: Update to use the new options, instead of
+ the deprecated. `--acdir'.
+ * m4/dirlist: Move ...
+ * m4/acdir/dirlist: ... here.
+ * m4/Makefile.am (EXTRA_DIST): Update.
+ (m4datadir): Rename ...
+ (automake_acdir): ... to this. Accordingly, ...
+ (dist_m4data_DATA): ... rename this ...
+ (dist_automake_ac_DATA): ... to this.
+ (system_acdir): New, directory.
+ (dist_system_ac_DATA): New, defined to an empty value; this will
+ ensure that the $(system_acdir) directory will be created by
+ "make install".
+ * tests/aclocal.test: Remove check about the `--print-ac-dir'
+ option of aclocal, it has been moved into ...
+ * tests/aclocal-print-acdir.test: ... this new test, and quite
+ extended.
+ * tests/aclocal-acdir.test: New test.
+ * tests/Makefile.am (TESTS): Add the new tests.
+ * NEWS, bootstrap: Update.

+
+ testsuite: revamp generation of autogenerated tests
+ With this change, we make generated tests be real scripts again
+ -- albeit only thin layers around the tests they wrap. It turned
+ out that the apparently clever tricks we played by having lots
+ of custom (and auto-generated) `..._LOG_COMPILER' variables and
+ by having the tests in $(wrap_TESTS) not being real on-file-system
+ scripts caused more pain and confusion than expected, for only
+ marginal gains. Also, that previous setup didn't interact very
+ well with "make check RECHECK_LOGS=", since the log files for
+ the "wrappee" tests were always considered out-of-date (which in
+ hindsight is natural, since these log files depended on wrappee
+ tests that didn't exist -- and weren't created). And finally, it
+ wasn't possible to easily and naturally run the wrappee tests
+ from the command line -- definitely harmful for debugging and
+ sanity checking.
+ * tests/gen-wrap-tests: Deleted, its role subsumed into ...
+ * tests/gen-tests-deps: ... this script, with the help of
+ (unindent, atomic_write, build_matcher, write_wrapper_script,
+ %test_generators): ... these new functions and variables.
+ Other few minor fixlets and improvements.
+ * tests/wrap-tests.sh: Delete, not needed anymore.
+ * tests/Makefile.am ($(srcdir)/wrap-tests.am): Don't generate
+ nor include anymore.
+ (EXTRA_DIST): Update.
+ (wrap_TESTS): Renamed to ...
+ (generated_TESTS): ... this.
+ ($(generated_TESTS)): Must have the same dependencies of
+ `$(srcdir)/tests-deps.am'.
+ Other minor related reordering and adjustments.
+ * bootstrap: Do not generate `wrap-tests.am' anymore.
+ * tests/.gitignore (wrap-tests.am): Don't ignore anymore.
+ (*-w.test, *-w.tap): Ignore.
+ * tests/README: Update paragraph on automatically-generated
+ tests.

+ Remove hand-written dependencies for tests. Other related

+ (handwritten_TESTS): ... this.
+ * tests/.gitignore (tests-deps.am): New ignored file.

+2011-08-25 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ coverage: more about escaping of TAP directives
+ * tests/tap-escape-directive.test: Make grepping of testsuite

+
+ tap: improve syncing between awk+shell and perl implementations
+ * lib/tap-driver.pl (stringify_test_result): Renamed ...
+ (stringify_result_obj): ... to this. Break up a clause in the
+ long "if/elsif/.../else" construct to avoid unaesthetic line
+ breaks and to be more synced with the sibling function in
+ `tap-driver.sh'. Rename the `$result', `$PASS' and `$FAIL'
+ variables to respectively `$result_obj', `$COOKED_PASS' and
+ `$COOKED_FAIL', for clarity and better syncing.
+ (handle_tap_test): Renamed ...
+ (handle_tap_result): ... to this, and change the name of the
+ `$test' local variable to `$result_obj'.
+ (extract_comment): Reimplement using the simpler `index' and
+ `substr' builtins, rather than with more advanced uses of
+ regular expressions.
+ (%test_results, @test_results): Renamed respectively ...
+ (%test_results_seen, @test_results_list): ... to these, and
+ related adjustments throughout the `TEST_RESULTS' block.
+ (main, get_global_test_result): Refactor and do some cosmetic
+ changes to make these functions clearer and better synced with
+ sibling code in `tap-driver.sh'.
+ Other minor cosmetic and typo fixes.
+ * lib/tap-driver.sh (extract_tap_comment): Remove outdated
+ "FIXME" comments.
+ (get_global_test_result): Small reordering to make it better
+ synced with its sibling function in `tap-driver.pl'.
+ (stringify_result_obj): Consistently use `result_obj' as the
+ parameter name.
+ Other minor cosmetic and typo fixes.
+
+2011-08-25 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/perl: don't redirect perl warnings/errors to log files
+ With this change, the test `tap-driver-stderr.test' also passes
+ with the perl implementation of the TAP driver.
+ * lib/tap-driver.pl (start): Save the original stderr into the
+ `OLDERR' file handle, and call ...
+ (trap_perl_warnings_and_errors): ... this new function, trapping
+ the `__WARN__' and `__DIE__' "pseudo-signals" to ensure that the
+ warning and error messages goes to that original stderr stream.
+ Since we are at it, be sure to prepend all possible "die" message
+ with the name of the script as given by the `$ME' variable.
+
+2011-08-25 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/perl: add copyright notice, version string, and emacs stuff
+ * lib/tap-driver.pl: Add proper copyright notice and bug reporting
+ address. Remove obsolete heading comments. Add trailing comments
+ for emacs w.r.t. code-formatting rules and automatic updating of
+ the date-based script version saved into the `$VERSION' variable.
+ ($VERSION): Define to the current UTC date.
+
+2011-08-24 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: don't redirect awk stderr to log files
+ * lib/tap-driver.sh: Handle the file descriptors redirections
+ more smartly, to avoid sending error messages from awk (about
+ e.g. syntax or I/O errors) to the log files instead that to the
+ console.
+ * tests/tap-driver-stderr.test: New test, verifying the improved
+ driver behaviour. Notice that this test still fails when using
+ the perl implementation of the TAP driver.
+ * tests/Makefile.am (tap_other_tests): Update.
+
+2011-08-24 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: remove obsolete "FIXME" comment
+ * lib/tap-driver.sh: Remove obsolete "FIXME" comment about our

+ has been solved in precedent commit `v1.11-1052-gd630a0d'. Fix
+ an unrelated typo in comments since we are at it.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ testsuite: avoid spurious failure on Solaris
+ * tests/tap-signal.test (signal_caught): Fix a regression from
+ commit `v1.11-1052-gd630a0d' that was causing this test to fail
+ spuriously on Solaris (due to an already worked-around Solaris
+ /bin/sh bug, see commit `v1.11-981-g0ef3ef5').
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ testsuite: use the new awk+shell TAP driver in our own testsuite
+ * tests/Makefile.am (TAP_LOG_DRIVER): Redefine to use the new
+ awk+shell tap driver, which should be complete enough for use in
+ a "controlled" production environment.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: handle non-zero exit status from the test command
+ * lib/tap-driver.sh (get_test_exit_message): New function in the
+ awk script, used to extract the exit status of the test program,
+ or at least a good guess of it.
+ (write_test_results): Use it, reporting an ERROR result if it
+ detects that the test program exited with a non-zero status.
+ * tests/tap-signal.test: Account for the differences in the
+ error messages generated by the awk and perl TAP drivers. Fix
+ an unrelated typo in comments since we are at it.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: prepare to fetch the exit status of the test command
+ * lib/tap-driver.sh: Rewrite some logic in the main parsing loop,
+ to make it possible to read the exit status of the test command
+ from the last line of the input stream.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: refactor for future changes
+ * lib/tap-driver.sh: Rewrite the awk script so that the parsing
+ of the input stream is implemented as a hand-rolled loop in the
+ BEGIN block, using the `getline' builtin.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ testsuite: avoid spurious failure if rst2html program is missing
+ * tests/tap-html.test ($required): Require `rst2html'.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: support Solaris /usr/xpg4/bin/awk
+ * lib/tap-driver.sh: Use `\t', not `\\t', to represent tabulation
+ character in regexps, even when inside double-quoted strings; that
+ seems to be more portable to Solaris 10 XPG4 awk.
+
+2011-08-22 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: support Solaris /usr/bin/nawk
+ * lib/tap-driver.sh (close_or_die): Remove, the use of the `close'
+ builtin in there was confusing /usr/bin/nawk from Solaris 10 into
+ a syntax error.
+ (write_test_results): Simply use `close' on the `*.trs' file, that
+ should be enough.
+
+2011-08-21 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: correctly extract message from SKIP plans
+ * lib/tap-driver.sh (/^1\.\.0+[ \t]*#/): Add a forgotten `?' to
+ the regex used to extract the skip message from a "1..0" TAP plan.
+ * tests/planskip.test: Check for the just-fixed bug.
+ * tests/tap-planskip-unplanned-corner.test: Don't be too strict
+ w.r.t. the formatting of the "skip whole test" message, to avoid
+ failing due to bugs irrelevant for this test (like the one just
+ fixed).
+
+2011-08-21 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap/awk: support colorized output
+ * lib/tap-driver.sh: Pass definition of colors to the BEGIN block
+ of the awk script, using ...
+ ($init_colors): ... this new variable, which supersedes ...
+ ($red, $grn, $lgn, $blu, $mgn, $std): ... these variables, which
+ have been consequently removed.
+ ($color_tests): We don't have to pass this anymore to the awk
+ script, so do not convert it to a numeric boolean.
+ (decorate_result): Implement for real.
+ With this change, the test 'tap-color.test' now passes.
+
+2011-08-21 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap: real (but still incomplete) awk implementation of TAP driver
+ * lib/tap-driver.sh: Add an incomplete, but mostly working,
+ implementation of a TAP parser and driver in awk. It doesn't yet
+ support colorized output, fetching of exit status from test
+ programs, nor a way to escape TAP directives in TAP result lines,
+ but passes all the tests of TAP support in the automake testsuite,
+ apart from the following ones:
+ - tap-color.test
+ - tap-escape-directive.test
+ - tap-exit.test
+ - tap-missing-plan-and-bad-exit.test
+ - tap-passthrough-exit.test
+ - tap-planskip-badexit.test
+ - tap-planskip-unplanned-corner.test
+ - tap-signal.test
+ Tested on Debian GNU/Linux with GNU awk 3.1.7 and 3.0.2, "original
+ awk" 2010-05-23-1, and mawk 1.3.3-15 (with which also the test
+ `tap-realtime.test' fails, in addition to those listed above).
+
+2011-08-21 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ testsuite: fix spurious failure due to Solaris 'wc' incompatibility
+ * tests/tap-number-wordboundary.test ($planned): Strip any extra

+
+ coverage: some more tests on corner cases of TAP support
+ * tests/tap-no-spurious.test: Extend checks verifying that a line

+ * tests/tap-no-spurious-numbers.test: New test, checking that our

+
+ testsuite: various fixlets and tweakings
+ * tests/seenc.test: Make grepping of automake stderr stricter.
+ Add a trailing `:' command.
+ * tests/symlink.test: Likewise. Also, define `$am_create_testdir'
+ to "empty" to avoid bringing in unused auxiliary files (only to
+ have to remove them right away), and use proper m4 quoting in
+ `configure.in'.
+ * tests/vpath.test: Make grepping of generated `Makefile.in'
+ slightly stricter. Prefer trailing `:' over trailing `Exit 0'.
+ * tests/suffix6c.test: Unset OBJEXT to avoid interferences from
+ the environment.
+ * tests/suffix12.test: Do not whitespace-indent `##' comments
+ when they are embedded in a makefile rule: having them indented
+ is not part of the Automake API, and might cause failures with
+ e.g., Tru64 make.
+ * tests/syntax.test: Simplify the `Makefile.am' to ensure that

+
+ parallel-tests: no more spurious successes for FreeBSD make
+ Work around a bug of FreeBSD make bug that was causing the
+ automake-generated "check" target to complete with success
+ even if some tests failed; this happened only when FreeBSD
+ make was run in concurrent mode (as in, e.g., "make -j2
+ check"). The bug is not present in NetBSD make.
+ This change fixes automake bug#9245:
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9245>
+ See also FreeBSD PR bin/159730:
+ <http://www.freebsd.org/cgi/query-pr.cgi?pr=159730>
+ * lib/am/check.am [%?PARALLEL_TESTS%] $(TEST_SUITE_LOG): Use a
+ more "safe" (and apparently redundant) idiom to exit with error,
+ so that the non-zero exit status is picked up also by FreeBSD
+ make when it's running in concurrent mode.
+ * NEWS: Update.
+ * tests/check-concurrency-bug9245.test: New test.

+2011-08-17 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ tap: correctly handle string "0" in TAP messages
+ * lib/tap-driver.pl (is_null_string): New function, can be used
+ to determine whether a given string variable is empty or undefined.
+ Useful to avoid pitfalls like:
+ if ($message) { print "$message\n"; }
+ which wouldn't print anything if $message is the literal "0".
+ (handle_tap_test, handle_tap_plan, handle_tap_bailout): Use it,
+ to avoid missing messages composed only by a literal "0" in TAP
+ result descriptions and in skip, todo and bailout explanations.
+ * tests/tap-message-0.test: Enhance.
+ * tests/Makefile.am (XFAIL_TESTS): Remove it, it passes now.

+
+ tap: add a dummy TAP driver script implemented in shell + awk
+ The user can also now decide which implementation of the TAP driver
+ to use in the testsuite by defining the `$am_tap_implementation'
+ variable to either "perl" or "shell". Future enhancements will
+ allow the testsuite to automatically run the test scripts on TAP
+ support with both the TAP driver implementations, to improve
+ coverage.
+ * tests/defs (fetch_tap_driver): Honor the `$am_tap_implementation'
+ variable to decide which implementation of the TAP driver to fetch.
+ ($am_tap_implementation): Default to "perl".
+ * tests/tap-common-setup.test: Do not fetch the TAP driver, the
+ code in tap-setup.sh does that already (and respecting runtime
+ overriding of `$am_tap_implementation').
+ * lib/tap-driver: Renamed ...
+ * lib/tap-driver.pl: ... to this, and ...

+2011-08-17 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ testsuite: refactor tests on TAP support in view of future changes
+ * tests/defs (fetch_tap_driver): New subroutine; it fetches the

+ current directory, and edits its shebang line so that it will be
+ run with the perl interpreter determined at configure time.
+ * tests/tap-setup.sh: Use it.
+ * tests/tap-common-setup.test: There's no need to AC_SUBST `PERL'
+ anymore, nor to use it in the Makefile to run the TAP driver.
+ Also, use the `fetch_tap_driver' function instead of copying the

+ tap: non-zero exit status after "Bail out!" should not be reported
+ This new behaviour is more consistent with that of the `prove'

+
+ testsuite: improve interface for giving early TAP plan
+ Since commit `v1.11-976-g4740f56', an early TAP plan can also be
+ specified after input lines have already been seen, as long as
+ no one of them is a TAP result line. We can now take advantage
+ of this in our own testsuite, allowing the TAP-based scripts to
+ specify their earlier plan after having included `./defs'. In
+ particular, this offers the benefit of allowing those scripts to
+ issue a "skip all" plan (e.g., "1..0 # SKIP reason ...") after
+ the inclusion of `./defs', which wasn't possible with the older
+ interface (introduced in commit `v1.11-1114-g0286308').
+ * tests/defs: Don't try to call `plan_' if `$planned' is defined,

+
+ test defs: get name of TAP-using tests correctly
+ This change fixes the names of the temporary directories used
+ by the TAP-based tests (e.g., test `foo.tap' now uses `foo.dir'
+ rather than `foo.tap.dir'); more importantly, this make the
+ variable `$destdir' defined in `tests/defs' usable also in the
+ TAP tests.
+ ($me): Also strip the any `.tap' suffix from the name of the
+ test.
+
+2011-08-07 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ testsuite: TAP tests properly decide when to remove tempdirs
+ Before this change, the TAP tests in the Automake testsuite were
+ removing the temporary test directory even when they failed or
+ were skipped, thus making debugging more difficult.
+ * tests/tap-functions.sh (incr_tap_count): Removed, superseded
+ by ...
+ (incr_): ... this function, which can increment the value of any
+ variable passed to it.
+ (result_): Updated to use `incr_' instead of the now-removed
+ `incr_tap_count_'. Keep count of failures, xfailures, xpasses,
+ and skips, using ...
+ ($tap_skip_count_, $tap_bad_count, _$tap_xfail_count_): ...
+ these new variables.
+ * tests/defs (trap): Try to use their values to decide whether

+
+ tap: scripts with a SKIP plan but with exit status != 0 must error
+ This change has been motivated by Automake's own testsuite. Some
+ TAP tests there were erroring out (due to unexpected, unhandled
+ failures) before having encountered TAP result, so that the
+ simple-minded shell library implementing TAP generation ended up
+ printing a "1..0" trailing test plan; this caused the script to be
+ reported as a SKIP rather than an ERROR -- a nasty false negative.
+ * lib/tap-driver: Add prototypes for each subroutine, to free up
+ the order in which they can be defined and called.
+ (main): Move the code checking for a bad exit status of the TAP
+ producer ...
+ (finish): ... here, and flush the TAP stream to ensure that the

+
+ testsuite: scaffolding to allow use of TAP in our own tests
+ Now that Automake has initial support for the TAP test protocol,
+ we can start "eating our own dog food" and rewrite some tests to
+ use TAP; this should allow for better granularity, especially in
+ the control of skips and expected failures. With this change, we
+ set up the initial scaffolding required by the planned TAP tests,
+ and convert few older tests to use TAP, mostly in order to verify
+ that there are no obvious errors. The tests in our testsuite that

+ `$use_tap' is set to "no" or "yes".
+ (exit trap): Call `late_plan_' if `$use_tap' is true. Also,
+ unset shell traces before issuing the latest commands, to avoid
+ confusing the tap driver with spurious output.
+ * tests/defs-static.in ($use_tap): New variable, by default set

+
+ test harness: use new `.trs' files to hold test metadata
+ With this change, the test harness will keep test metadata in
+ dedicated `.trs' files, instead of having them embedded into the

+ format of the `.log' files. Note that this change makes the

+ * lib/am/check.am (am__test_driver_flags): Rename ...

+ (am__TEST_BASES): New internal variable, holding the names of
+ the tests, with any registered extension removed.
+ (am__stealth_MAKE): New internal variable, can be used instead of
+ $(MAKE) in recipes requiring a recursive call to make, but which
+ are not intended to be executed by "make -n".
+ (.log.trs): New suffix rule, to recover from deletion of `.trs'
+ files.
+ ($(TEST_SUITE_LOG)): Almost completely rewritten to follow the

+
+ test harness: allow more metadata in log files
+ This change reworks and improves the parallel test harness to use
+ more specialized reStructuredText fields in the log files (instead
+ of relying on specially-placed of "magic lines" and more indirect
+ semantical formatting); the new fields are the following:
+ - ":recheck:": tell whether the associated test will have to be
+ re-run by "make recheck";
+ - ":copy-in-global-log:": tell whether the content of the log
+ file should be copied in the "global log" `test-suite.log';
+ - ":end-metadata:", which inhibits the scanning of the rest of
+ the log file (for what concerns test metadata).
+ Also, the special `:test-result:' value "END" has been removed,

+
+ parallel-tests: make parsing of test results safer
+ The new code for parsing the testsuite-generated `.log' files,
+ as introduced in commit `v1.11-872-gc96b881', considers each
+ `:test-result:' field anywhere in a `.log' file as a declaration
+ of a test result, and accounts for it as such in the testsuite
+ summary. Unfortunately this could easily cause spurious test
+ failures being reported in the testsuite summary. This happened
+ in practice with the Automake's own testsuite; for example:
+ $ make check TESTS='check12-p.test'; echo exit: $?
+ ...
+ PASS: check12-p.test
+ =====================================
+ 4 of 5 tests failed
+ See tests/test-suite.log
+ Please report to bug-automake@gnu.org
+ =====================================
+ make[2]: *** [test-suite.log] Error 1
+ make: *** [check-am] Error 2
+ exit: 2
+ This change introduces a new special `:test-result:' "END", that,
+ when seen, prevents the rest of the log file from being parsed.

+
+ parallel-tests: add auxiliary script 'test-driver', refactor
+ This refactoring should cause no API of functionality change,
+ and is meant only to simplify the future implementation of TAP
+ and SubUnit testsuite drivers. More precisely, our roadmap is
+ to move most of the "testsuite driving" features out of the
+ Automake-generated Makefiles, and into external scripts with
+ well-defined interfaces. This will allow the user to define
+ its own personalized testsuite drivers, and will also offer us
+ a framework upon which to implement our new TAP and SubUnit
+ drivers, all in a very unobtrusive way and retaining an high
+ degree of code reuse and backward-compatibility.
+ * lib/test-driver: New auxiliary script.
+ * lib/Makefile.am (dist_SCRIPT_DATA): Add it.
+ * automake.in (handle_tests): Require the new auxiliary script
+ `test-driver', and define a new internal makefile variable
+ `$(am__test_driver)', used to call it. Perform new substitution
+ on `DRIVER' when processing the `check2.am' file.
+ * lib/check.am (am__tty_colors): Define new shell variable
+ `$am__color_tests'.
+ (am__rst_section): Removed, its role taken over by the new
+ `test-driver' script.
+ (am__test_driver_flags): New variable, contains the command
+ line options passed to `test-driver'.
+ (am__check_pre): Do not deal with temporary files and exit
+ traps anymore, as the `test-driver' script takes care of that
+ now. Define shell variable `$am__enable_hard_errors', used by
+ `$(am__test_driver_flags)'. Reorder so that we don't need to
+ save and restore the value of the `TERM' environment variable
+ anymore.
+ Other related adjustments.
+ (am__check_post): Remove, as its role has been completely taken
+ over by the `test-driver' script.
+ * am/check2.am (?GENERIC?%EXT%$(EXEEXT).log, ?GENERIC?%EXT%.log,
+ ?!GENERIC?%OBJ%): Call the test script through the Automake
+ substituted `%DRIVER%', and honor the command-line options
+ in `$(am__test_driver_flags)'. Do not call the obsoleted
+ `$(am__check_post)' anymore.
+ * doc/automake.texi (Auxiliary Programs): Mention the new
+ `test-driver' script.
+ (Optional): Mention `test-driver' in AC_CONFIG_AUX_DIR.
+ Since we are at it, break the list of auxiliary scripts by
+ placing one per line, to simplify potential future additions
+ of new scripts.

+ test defs: fix ksh-related portability bug in warning messages
+ Running "make check" normally prints a diagnostic to the outermost
+ stderr (usually a tty) to explain why a test is skipped, thus
+ giving better and faster feedback to the user. It used to do
+ so by redirecting file descriptor 9 to stderr (via "exec 9>&2")
+ before invoking the test scripts, which then would write any skip
+ explanation to file descriptor 9 via the `skip_' function defined
+ in `tests/defs'.
+ However, various Korn Shells (at least Solaris 10's /bin/ksh and
+ Debian GNU/Linux's /bin/ksh) and the HP-UX's /bin/sh close open
+ file descriptors > 2 upon an `exec' system call; thus the effects
+ of "exec 9>&2" are cancelled upon fork-and-exec, so we would get
+ a "Bad file number" diagnostic and no skip explanation with those
+ shells.
+ The present change remedies this situation.
+ * tests/Makefile.am (AM_TESTS_ENVIRONMENT): Redirect more portably,
+ via a trailing "9>&2", rather than the prior "exec 9>&2; ...". Add
+ explanatory comments.
+ * tests/defs (stderr_fileno_): Update the advice in comments.
+ Based on commit v8.12-82-g6b68745 "tests: accommodate HP-UX and

+ Before this patch, the only way offered by tests/defs to
+ properly signal a hard error was the `framework_failure_'
+ function. But the error message issued by that function,
+ as its name would suggest, refers to a set-up failure in the
+ testsuite, while hard errors can obviously also be due to

+ introduce a new function with a more general error message.
+ Inspired by a recent similar change to Gnulib's tests/init.sh.
+ * tests/defs (fatal_): New function.
+ * tests/README (Section "Writing test cases" subsection "Do"):

+
+ tests: `lib/' shell scripts transparently tested also with $SHELL
+ With the previous commit, the user could prefer the use of $SHELL
+ over /bin/sh in some tests checking the Automake-provided shell
+ scripts by manually exporting `test_prefer_config_shell' to "yes"
+ in the environment. With this commit, we ensure that such tests
+ *always* and *transparently* run using both $SHELL and /bin/sh
+ to execute the checked scripts. The `test_prefer_config_shell'
+ variable becomes an internal detail, and is no more meant to be
+ manually defined or overridden.
+ * tests/defs-static.in: Check that `test_prefer_config_shell' is
+ not exported in the environment. Error out if this is the case.
+ * tests/config-shell-tests.sh: New file, driver script to run
+ checks on the shell scripts in `lib/' using the $SHELL determined
+ at configure time instead of the default system shell /bin/sh.
+ * Makefile.am (TESTS_EXTENSIONS): Add `.shtst'.
+ (SHTST_LOG_COMPILER): Define, it calls `config-shell-tests.sh'.
+ (config_shell_tests): Define to a list of tests that wraps other
+ `*.test' tests using `config-shell-tests.sh'.
+ ($(config_shell_tests)): Dummy dependency declaration required
+ in order to have make actually produce expected log files from
+ the `.shtst.log' suffix rule.
+ (EXTRA_DIST): Distribute `config-shell-tests.sh'.
+ (TESTS): Add `$(config_shell_tests)'.
+ * tests/self-check-env-sanitize.test: Update, by checking that
+ `test_prefer_config_shell' isn't exported in the environment.

+ tests: can use also $SHELL to check shell scripts from `lib/'
+ * tests/ar-lib.test: If the variable `$test_prefer_config_shell'
+ is set to "yes", run the script under test with configure-time
+ determined $SHELL, rather than with /bin/sh.
+ The `$test_prefer_config_shell' variable defaults to empty, but
+ can be overridden at runtime by the user, thus allowing more
+ coverage.

+
+ tests defs: better requirements for XSI shells
+ This change avoids potential spurious failures with tests using
+ the requirement 'xsi-shell' to mean that they want */bin/sh* (not
+ $SHELL) to be XSI-conforming. This idiom used to work before
+ commit `v1.11-874-g1321be7' (as back then the test scripts were
+ unconditionally run with /bin/sh), but has become inconsistent
+ now that the test scripts re-execute themselves with configure
+ determined $SHELL.
+ The described spurious failures have already occurred in practice,
+ for examples on Solaris systems which also had GNU Bash installed.
+ From a suggestion by Peter Rosin. See discussion at:
+ <http://lists.gnu.org/archive/html/automake-patches/2011-06/msg00016.html>
+ * tests/defs (xsi-shell): Now check that $SHELL, rather than the
+ shell currently running the test script, is an XSI shell.
+ (xsi-bin-sh): New requirement, checking that /bin/sh (which can
+ differ from $SHELL) is an XSI shell.
+ (xsi-lib-shell): New requirement, checking that the shell that
+ should be used to test the Automake-provided scripts from `lib/'
+ is an XSI shell. For the moment, this is just an alias for
+ `xsi-bin-sh'.
+ (require_xsi): New subroutine, used to factor out code common to
+ the requirements above.
+ ($xsi_shell_code): New variable, contains shell code supposed to
+ work only with XSI shells. Used by the new subroutine above.
+ * tests/ar-lib.test ($required): Require 'xsi-lib-shell' instead
+ of 'xsi-shell', since the script we test here is run with /bin/sh,
+ not with $SHELL.

+ tests: fix typo-related error in auxdir2.test
+ * tests/auxdir2.test (configure.in): Close m4 quoting in the
+ argument to AC_CONFIG_AUX_DIR. Without this, aclocal fails with
+ "ERROR: end of file in string". This problem hasn't been exposed
+ by the testsuite before because this test is in XFAIL_TESTS, so
+ its failure went unnoticed, even if it was due to a wrong cause.

+ and formatting.
+ * tests/silent-many-generic.test: The C++ compiler from Sun Studio
+ is named `CC', and this can cause spurious failures in our grepping

+ around the C++ compiler (generated on the fly), since filtering the
+ make output proved to be too fragile.

+ tests: prefer ulimit over timeout in test on a memory-hogging bug
+ * tests/cond29.test: Use 'ulimit' instead of 'timeout' to ensure
+ that automake does not uses up too much resources. This is really
+ and improvement because the bug tested by this script wasn't just
+ a "it hangs" or "it runs too slow" bug, but rather a memory-hogging
+ bug (due to combinatorial explosion when many Automake conditionals
+ had to be handled) which could easily crash the whole system, which
+ is unacceptable. The requirement of a proper and working 'ulimit'
+ builtin might cause the test to be skipped on more systems, but
+ that shouldn't be a problem since the bug isn't about a portability
+ issue, but is rather an automake internal implementation problem.
+ I've verified that the test as updated by this patch still passes
+ with automake 1.8.5, automake 1.10.2, and obviously the development
+ version of automake, and that it fails with automake 1.7.9.

+ automake, aclocal: honour configure-time AUTOCONF and AUTOM4TE
+ Currently, the Automake's own configure script allow definition
+ of AUTOCONF and AUTOM4TE, expected to point respectively to an
+ autoconf and autom4te programs. But while these definitions are
+ honoured in the Automake's build systems and test suite, they
+ were *not* honoured in the generated `automake' and `aclocal'
+ scripts. This behaviour, apart from being wrong in that it does
+ not allow the user enough freedom in choosing his tools, also
+ caused inconsistencies in the test suite, brining to spurious

+ tests/README: fix example about `make -e' usage
+ * tests/README (Section "Writing test cases" subsection "Do"): When
+ some variable is never initialized in the Makefile, `-e' is not
+ necessary in order to override it. DESTDIR is such a variable: we
+ ensure that we do not ever initialize it. And as such, it is quite
+ portable to use:
+ $ make DESTDIR=/foo/bar install
+ and in fact, quite widely used.
+ So our example about when `make -e' is required, which references
+ the `DESTDIR' variable, is poorly chosen, if not downright wrong.
+ Rewrite it to use `prefix' as the overridden variable instead.

+ The "avoid the requirement of a working compiler" we refer about

+ in `configure.in'.
+ The "cosmetic changes" we refer about below consists in, e.g.,
+ adding a trailing `:' command to a script, using proper m4 quoting
+ in `configure.in' files, adding commands that offer more debugging
+ output, explicitly declaring phony targets as such in Makefiles,
+ making use of idioms more consistent with those employed in other

+ lex tests: avoid spurious failures when LEXLIB isn't found
+ The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
+ the "lex library" expected to provide a `yywrap' function (function
+ which is required to link most lex-generated programs). On the
+ contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
+ fail, configure declares that no lex library is needed, and simply
+ proceeds with the configuration process -- only for the build to
+ possibly fail later, at make time.
+ This behaviour might be (partly) intended; the Autoconf manual
+ reads:
+ ``You are encouraged to use Flex in your sources, since it is
+ both more pleasant to use than plain Lex and the C source
+ it produces is portable. In order to ensure portability,
+ however, you must either provide a function `yywrap' or, if
+ you don't use it (e.g., your scanner has no `#include'-like
+ feature), simply include a `%noyywrap' statement in the
+ scanner's source.''
+ This AC_PROG_LEX behaviour is causing some spurious failures of the
+ Automake testsuite in environments which lack a proper library
+ providing `yywrap' (this happens for example in Linux->MinGW cross
+ compilations). But at this point is clear that a proper workaround
+ is to simply provide a fall-back implementation of `yywrap' in our
+ lexers.

+
+ testsuite: allow user to ask for stricter skip semantics
+ Given how the Automake testsuite is currently structured, if a
+ command in a test script fails with status `77', the global test
+ outcome is considered a SKIP, because the value of `77' for `$?'
+ is passed to the exit trap. Indeed, this happens in practice, as
+ an autoconf-generated configure script can exit with status `77'
+ if it fails to find, e.g., a required compiler.
+ While this behaviour is quite useful for avoiding spurious test
+ failures in the wild, it can also sometimes prevent the Automake
+ developers to easily see and declare the requirements of their
+ tests.
+ This change introduces a new variable `am_explicit_skips', meant to
+ be user-overridable, and which, when set to a "true" value (i.e.,
+ `yes' or `1'), require a direct call to `Exit 77' in order to make
+ the test outcome be considered a SKIP.
+ * tests/defs.in ($am__test_skipped): New variable, initialized
+ to `no'.
+ (Exit): Set `$am__test_skipped' to `yes' if passed an exit status
+ of 77.
+ (trap '...' 0): When `$am_explicit_skips' is set to a "true" value,
+ reset an exit status of `77' to `78' if $am__test_skipped is not
+ set to `yes'.
+ * tests/self-check-exit.test: Adjust: unset `am_explicit_skips'.
+ * tests/self-check-explicit-skips.test: New test.

+
+ lex: "make clean" removes .c files from non-distributed .l
+ Previously, while automake did *not* distribute C source and header
+ files derived from non-distributed Lex sources, it still caused
+ them to be removed only by "make maintainer-clean" only, and not by
+ simply "make clean" or "make distclean".
+ This caused "make distcheck" to fail, unless the developer put
+ those generated .c files in CLEANFILES or in DISTCLEANFILES by
+ hand.
+ This change fixes this issue, by making non-distributed `.c' files
+ generated by non-distributed Lex sources cleaned by "make clean".
+ A similar problem for Yacc support had been fixed with the commit
+ v1.11-263-ged2c8bc.
+ * tests/automake.in (lang_lex_target_hook): Make C source files
+ derived from non-distributed Lex files cleaned by "make clean",
+ not only by "make maintainer-clean".

+
+ lex tests: remove erroneous check about ylwrap distribution
+ * tests/lex5.test: Do not check that the ylwrap script is *not*
+ distributed when there is only one lexer, as ylwrap is in fact
+ expected to distributed unconditionally (at least starting from
+ commit `Release-1-9-323-gc5881cc' of 19-08-2006). Note that this
+ bogus check wasn't triggering any failure because it was done at
+ the wrong time (i.e. from the VPATH build directory), so that it
+ could never fail anyway.
+ Instead, check that ylwrap is distributed even when there is only
+ one lexer.
+ Since we are at it, add a couple of `ls -l' calls, to get better
+ debugging info.

+ yacc: "make clean" removes .c and .h files from non-distributed .y
+ Previously, while automake did *not* distribute C source and header
+ files derived from non-distributed Yacc sources, it still caused
+ them to be removed only by "make maintainer-clean" only, and not by
+ simply "make clean" or "make distclean".
+ This caused "make distcheck" to fail, unless the developer put
+ those generated .c and .h files in CLEANFILES or in DISTCLEANFILES
+ by hand.
+ This change fixes this issue, by making non-distributed `.c' and
+ `.h' files generated by non-distributed Yacc sources cleaned by

+ python: fix spurious failure in tests
+ * tests/python-vars.test: Ignore cached values from config.site
+ by exporting CONFIG_SITE=/dev/null. Be laxer in matching the

+ since they can change quite unpredictably among different python
+ installations. Also, avoid "hyping" debugging output, thus
+ offering smaller trace output and more informative diff.

+
+ yacc: "make clean" removes .c and .h files from non-distributed .y
+ Previously, while automake did *not* distribute C source and header
+ files derived from non-distributed Yacc sources, it still caused
+ them to be removed only by "make maintainer-clean" only, and not by
+ simply "make clean" or "make distclean".
+ This caused "make distcheck" to fail, unless the developer put
+ those generated .c and .h files in CLEANFILES or in DISTCLEANFILES
+ by hand.
+ This change fixes this issue, by making non-distributed `.c' and
+ `.h' files generated by non-distributed Yacc sources cleaned by
+ "make clean".

+ Fix parallel testsuite run with Zsh.

+ the $(TEST_LOG_COMPILER).
+ For more information, please refer to the thread "Fix parallel

+ <http://lists.gnu.org/archive/html/automake-patches/2010-12/msg00135.html>

+ or later, and offers better error messages (instead of random
+ failures) for earlier Zsh version.
+ * tests/README (Supported shells): When describing the manual
+ workaround about the Zsh incompatibility in the handling of `$0',
+ tell that it is now needed only with Zsh versions preceding 4.3.

+
+2010-11-10 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Tests defs: move static definitions in a new file `defs-static'.
+ The new file is meant to be idempotent w.r.t. multiple inclusions.
+ * tests/defs.in: Removed, its contents split among ...
+ * tests/defs-static.in: ... this new file ...
+ * tests/defs: ... and this new file, including the former.
+ * configure.ac (AC_CONFIG_FILES): Remove `tests/defs', add
+ `tests/defs-static'.

+ * tests/Makefile.am ($(parallel_tests)): Update.
+ ($(instspc_tests)): Likewise.
+ * tests/.gitignore: Update.
+
+ Tests defs: $testsbuilddir is now AC_SUBST'ed.
+ * tests/defs.in ($testsbuilddir): Substitute from @abs_builddir@.
+ Add sanity check on $testsbuilddir, similar to those on
+ $testsrcdir and $top_testsrcdir.
+
+ Tests defs: do not print message "Running test $0" anymore.
+ * tests/defs.in: Printing the message "=== Running test $0" at
+ the beginning of each tests made sense when Automake used the old
+ test-driver, which sent all the output directly to stdout/stderr.
+ Now that the parallel test-driver is used, which saves output of
+ each test in its corresponding log file, that old message is just
+ useless noise.
+
+ Tests defs: rename $curdir -> $testbuilddir
+ * tests/defs.in: Rename $curdir to $testbuildir, for clarity and
+ consistency with $testsrcdir and $top_testsrcdir.
+
+ Tests defs: prefer "$curdir" over "`pwd`".
+ * tests/defs.in: We already save the value of `pwd` in $curdir
+ early in the file, so there no need to recalculate it later, when
+ the current working directory is not changed.
+
+ Tests defs: use `$me' in more error messages.
+ * tests/defs.in: Also use `$me' in error messages referring to
+ missing `defs' or `defs.in', since that variable is now defined
+ before those checks.
+
+ Tests defs: do not use `Exit' where plain `exit' suffices.
+ * tests/defs.in: Use "exit 77" rather than "Exit 77" to skip the
+ test when required libtool/gettext macros are not found, since
+ such skips would take place before the exit trap is installed.
+
+ Tests defs: improve and extends comments.
+ * tests/defs.in: Improve and extends some comments, especially in
+ relation with the changes introduced by the previous reordering.
+
+ Tests defs: various reorderings.
+ * tests/defs.in: Reordered various snippets of code in a
+ clearer way.

+
+ Fix bug in test `backcompat4.test' (stale autom4te cache).
+ * tests/backcompat4.test: Remove stale autom4te cache directory

+ to ease debuggability.
+ Reported by Ralf Wildenhues.
+
+2010-11-07 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Fix a bug in variable concatenation with `+='.
+ * lib/Automake/VarDef.pm (append): Since the content of the
+ "appended-to" variable is going to be unconditionally normalized
+ later, simply separate the appended value with a single whitespace
+ character, instead of trying to be uselessly smarter by using
+ escaped newlines. This fixes a bug in which extra backslashes
+ where erroneously inserted in the variable's final value.
+ * tests/pluseq11.test: New test, exposing the bug.
+ * tests/Makefile.am (TESTS): Update.
+ Reported by Andy Wingo.
+
+2010-11-07 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Modernize, improve and/or tweak various test scripts.
+ * tests/stamph2.test: Improve m4 quoting in `configure.in', and
+ prefer trailing `:' over trailing `Exit 0'.
+ * tests/syntax.test: Escape literal dots in grep regexps.
+ * tests/copy.test: Enable `errexit' shell flag. Extend test by
+ checking with `test' utility that the script `install-sh' is
+ copied, but not symlinked.
+ * tests/depdist.test: Move setting of `errexit' shell flag earlier
+ in the script (just after inclusion of ./defs). Avoid obsoleted
+ constructs in generated `configure.in'. Prefer to do our checks
+ by running configure and make over grepping Makefile.in.
+ * tests/target-cflags: Move setting of `errexit' shell flag
+ earlier in the script (just after inclusion of ./defs). Use the
+ `configure.in' stub created by `./defs', rather than writing it
+ from scratch.
+ * tests/target-clash: Do not uselessly run autoconf.
+ * tests/ctarget1.test: Renamed ...
+ * tests/cond-basic.test: ... to this. Use the `configure.in' stub
+ created by `./defs', rather than writing it from scratch.
+ Move setting of `errexit' shell flag earlier in the script (just
+ after inclusion of ./defs). Other minor cosmetic changes.
+ * tests/Makefile.am (TESTS): Updated.
+
+2010-11-06 Stefano Lattarini <stefano.lattarini@gmail.com>

+2010-11-06 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Fix bug in rules for creating vala vapi/header files.

+ of test `vala2.test'.
+
+2010-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
+
+ Fix and document rules to not touch the tree with `make -n'.
+ * doc/automake.texi (Multiple Outputs): Document the problem of
+ modifications during dry-run execution, propose solution.
+ * NEWS: Update.
+ * automake.in (lang_vala_finish_target): Split recipe so the
+ stamp file is not removed with GNU `make -n'.
+ (lang_yacc_target_hook): Separate removal of parser output file
+ and header remaking.
+ * lib/am/lisp.am ($(am__ELCFILES)): Determine whether -n was
+ passed to make, take care not to remove any files in that case.
+ * lib/am/remake-hdr.am (%CONFIG_H%): Separate removal of
+ %STAMP% file from induced remaking of config header.
+ * tests/autohdrdry.test, tests/lispdry.test, tests/yaccdry.test:
+ New tests.
+ * tests/Makefile.am (TESTS): Update.
+
+2010-11-05 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Fix potential bug in generated tests `instpc-*.test'.
+ This bug is due to the changes introduced by the recently-merged
+ "tests-init" branch. In that branch, `tests/defs' didn't define
+ anymore `$srcdir', instead defining directly `$testsrcdir'; but
+ the generated tests were using `$srcdir', hence the bug.
+ Luckily, since the Automake parallel test driver automatically
+ exports `srcdir' to a proper value, that prevented the bug from
+ manifesting itself.
+ * tests/Makefile.am ($(instspc_tests)): In the generated test
+ scripts, use `$testsrcdir', not `$srcdir'.
+
+2010-11-03 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Overhauled and modularized tests in `instspc.test'.
+ The test `instspc.test' was way too big and fragile. Its running
+ time was very long. It also produced a log that was nearly
+ unreadable due to its length, making it very difficult to find
+ out the reason for failures.
+ Also, it was too much monolithic, with a single (maybe spurious)
+ failure in a corner case causing the whole test to fail (even if
+ everything worked as expected in the other 99% of cases).
+ The present change should solve these problems, by separating
+ `instspc.test' into many smaller, self-contained, auto-generated
+ tests.
+ * tests/instspc.test: Removed.
+ * tests/instspc-tests.sh: New script, fulfilling a double role:
+ 1. it generates a Makefile.am snippet `tests/instspc-tests.am',
+ containing the definition of a list of new tests which will take
+ over the older `instspc.test', and
+ 2. it is sourced by said generated tests with proper parameters
+ pre-set, to run the "meat" of the checks.
+ This apparent abuse is indeed required because the test generation
+ code and test execution code are inevitably intertwined.
+ * tests/Makefile.am ($(srcdir)/instspc-tests.am): Include this
+ snippet, which (among the other things) defines ...
+ (instspc_tests): ... this new macro, containing the list of the
+ newly generated `instspc*.test' tests, and ...
+ (instspc_xfail_tests): ... this new macro, containing the list
+ of the `instspc*.test' tests expected to fail.
+ ($(instspc_tests)): New rule, generates the `instspc*.test' tests.
+ ($(instspc_tests:.test=.log)): New rule, registers the dependency
+ of all `instspc*.test' tests on the `instspc-tests.sh' script.
+ (TESTS): Add `$(instspc_tests)', remove `instspc.test'.
+ (XFAIL_TESTS): Add `$(xfail_instspc_tests)'.
+ (EXTRA_DIST): Distribute instspc-tests.sh.
+ (MAINTAINERCLEANFILES): Added $(instspc_tests).
+ Other minor cosmetic changes.
+ * bootstrap: Generate instspc-tests.am.
+ * tests/.gitignore: Updated.
+
+2010-11-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
+
+ Add FAQ entry for bug reporting instructions.
+ * doc/automake.texi (Reporting Bugs): New section.

+
+2010-10-07 Peter Rosin <peda@lysator.liu.se>
+
+ depcomp: add new one-pass depmode for MSVC 7 and later.
+ * lib/depcomp: Add new depmodes 'msvc7' and 'msvc7msys' which
+ make use of the -showIncludes option added in MSVC 7.
+ * m4/depend.m4 (_AM_DEPENDENCIES): Handle the new depmodes
+ similarly to 'msvisualcpp' and 'msvcmsys' as MSVC does not
+ support the -o option.
+
+2010-10-04 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Add support for newer python versions.
+ * m4/python.m4 (AM_PATH_PYTHON): Add python2.7 and python3.2 to
+ _AM_PYTHON_INTERPRETER_LIST. Since we are at it, break a long
+ line and fix indentation.
+ * THANKS: Updated.
+ From a report by Thomas Klausner.
+
+ Add test for `AM_WITH_DMALLOC' macro.
+ * tests/dmalloc.test: New test.
+ * tests/Makefile.am (TESTS): Update.
+
+ Fix nits and bugs in tests `help*.test'.

+ flags away from "$AUTOMAKE" and "$ACLOCAL".
+ * tests/help3.test: Likewise, and fix a botched comment.
+ * tests/help.test: Likewise. Also, use "AUTOMAKE_fails ..."
+ instead of "$AUTOMAKE ... && Exit 1", for consistency and to
+ please maintainer-check.
+ * tests/help2.test: Likewise.
+
+2010-10-03 Stefano Lattarini <stefano.lattarini@gmail.com>
+ Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
+
+ Improve tests `help*.test' (also fixes maintcheck failures).
+ * tests/help.test: To run automake, use `$AUTOMAKE' with all `-W'
+ flags stripped away rather than hard-coded `automake-$APIVERSION',
+ to better honour user-overrides. Similarly for aclocal.
+ * tests/help2.test: Likewise.
+ * tests/help3.test: Likewise.
+ * tests/help4.test: Likewise.
+
+2010-10-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

+
+ Extend tests on `--help' and `--version' options.
+ * tests/help.test: Create a new empty directory and chdir into

+
+ Manual: be more agnostic w.r.t. version control system used.

+ Wrap some MSVC options in the compile script.
+ * lib/compile: MSVC supports naming the output file, the option

+
+ Modernize and improve test scripts `subdir*.test'.
+ * tests/subdir.test: Enable `errexit' shell flag, and related

+ * tests/subdir3.test: Enable `errexit' shell flag, and related
+ changes. Do not create useless dummy source files.

+ `subdir5.test' here).
+ * tests/subdir6.test: Cosmetic change in spacing.
+ * tests/subdir9.test: Define and use new variable `$distdir'. Add
+ trailing `:' command.
+ * tests/subdir10.test: Cosmetic consistency-related change.
+ * tests/subdirbuiltsources.test: Cosmetic changes in spacings.

+ autoconf/automake macros.
+
+ Modernize and improve test scripts `dist*.test'.

+
+2010-07-18 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Improve and extend test cond5.test.
+ * tests/cond5.test: Do not blindly sleep 60 seconds before polling
+ the background automake process, but poll it every 10 seconds for
+ at most 30 times (this makes the test both faster on good machines,
+ and more resilient to spurious timeout-due failures when in low
+ priority or on heavily-loaded systems).
+ Check also that automake writes the expected error messages on the
+ standard error.
+ Enable `errexit' flag, and related changes.
+ Rely on the `configure.in' stub created by `./defs', rather than
+ writing one from scratch.

+ Tests: remove useless repetitions of `foreign' automake option.
+ * tests/multlib.test (configure.in): Remove useless use of
+ `foreign' option in AM_INIT_AUTOMAKE (the `--foreign' option is

+
+ New tests, exposing bugs in Automake Yacc/Lex support w.r.t.

+
+ Fix Autoconf version required by Automake's configure.
+ Automake configure script used to tell that automake required

+ * tests/conflnk3.test: Use `test -r FILE' and `test ! -r FILE'

+
+2010-04-20 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Make test badopt.test stricter (by enabling `set -e').
+ * tests/badopt.test: Add call to `set -e'. Due to this change,

+
+ Avoid possible false negatives in confh5.test.
+ * tests/confh5.test: Enable shell `errexit' flag, and bumped

+ in calls to $ACLOCAL, $AUTOMAKE, $AUTOCONF or $AUTOHEADER, or
+ a failure in grepping expected text in output files should now
+ cause the whole test to fail.
+
+2010-04-17 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Fixed typo in POD documentation of Automake::Channels.
+ * lib/Automake/Channels.pm: Fixed typo in POD documentation:

+
+ Fix connected warnings about obsolete exeext override.
+ * lib/Automake/Rule.pm (define): Merge two warnings that belong
+ together, by setting the 'partial' flag for the first one.
+
+ Fix per-Makefile.am setting of -Werror.
+ Before this patch, 'AUTOMAKE_OPTIONS = -Werror' in one
+ Makefile.am would carry over to other Makefile.am files

+
+ Make test `aclocal3.test' stricter.
+ * tests/aclocal3.test: Add call to `set -e'. Fail if $ACLOCAL

+
+ Avoid possible false negatives in cond46.test.
+ * tests/cond46.test: Enable shell `errexit' flag (and bumped

+
+2010-04-04 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Generated tests are now just a thin layer around other tests.

+
+2010-03-30 Stefano Lattarini <stefano.lattarini@gmail.com>
+
+ Avoid an unportable use of `$status' shell variable.
+ * Makefile.am (path-check): Don't use the `$status' shell variable
+ in the target's rules, as it's special in Zsh (equivalent to `$?',
+ and readonly).
+
+ Avoid another use of `chmod -R'.
+ * Makefile.am (path-check): To be safe, do not use `chmod -R' on
+ $(distdir) before removing it (as Solaris `chmod -R' touches
+ symlink targets). Instead, use the cleanup strategy used in
+ distdir.am.
+
+2010-03-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

+
+* think about how per-object flags should work. in particular:
+ * how should they be specified?
+ using the object name is confusing when .lo/.obj in use
+ however, the object name provides a nice interaction with
+ per-exe flags
+ * how should they interact with per-executable flags?
+ [ this is probably a feature in search of a problem ]
+
+* cross-compilation support:
+ programs built and used by the build process need to be
+ built for CC_FOR_BUILD
+ introduce a new prefxi for this, e.g. `build_PROGRAMS'
+ [ we can do this in an automatic way I think.
+ unfortunately it isn't that useful until autoconf has support
+ for this sort of thing as well ]
+
+* one performance enhancement would be to have autoconf write
+ a single file containing all the macro assignments.
+ then read this file via `include'
+ unfortunately this can't be done because of conditionals
+ -- but it could be made to work if we also changed:
+ * automake to rewrite @FOO@ to $(FOO), and
+ * the implementation of conditionals to rely on some new
+ config.status magic
+
+* support prog_LIBS as override for LIBS
+
+* Test subdir-objects option with yacc, lex, ansi2knr
+ Our locking scheme won't prevent a parallel make from losing
+ if there are two `bar.o' files and the timing is just right
+ This only happens with parallel make and no-`-c -o' compiler,
+ so it probably isn't very important
+ `-c -o' when doing libtool
+ try to find a losing compiler and see if it really works.
+ (actually: hack config.cache and do it)
+
+* per-exe flags
+** LIBOBJS shouldn't be used when there are per-exe flags (?)
+
+* Allow creation of Java .zip/.jar files in natural way
+ If you are building a compiled Java library, then the .zip/.jar
+ ought to be made automatically.
+
+* examine possibility of using any character in a macro name
+ and rewriting names automatically. this means we must rewrite
+ all references as well.
+ [ this is a 2.0-style feature ]
+
+* `distcheck' and `dist' should depend on `all'
+
+* Add code to generate foo-config script like gnome, gtk
+
+* document user namespace for macro/target names
+ adopt some conventions and use uniformly
+ [ this is a good thing for the rewrite ]
+
+* distclean must remove config.status
+ can't this cause problems for maintainer-clean?
+ shouldn't maintainer-clean print the message before running
+ any part of the make? (just to slow things down long enough
+ for the user to stop it)
+ (maybe doesn't matter since people who even know about
+ maintainer-clean already have a clue)
+
+* reintroduce AM_FUNC_FNMATCH which sets LIBOBJS
+ Then have automake know about fnmatch.h.
+ [ probably should wait for autoconf to get right functionality ]
+
+* "make diff" capability
+ look at gcc's Makefile.in to see what to do
+ or look at maint program
+
+* in --cygnus, clean-info not generated at top level
+
+* what if an element of a scanned variable looks like
+ $(FOO).$(BAR) ?
+ or some other arbitrary thing?
+ right now we try to cope, but not very well
+ [ this is only of theoretical interest for now ]
+ [ We now have an 'inner_expand' option to traverse_recursively,
+ but it is not yet used. ]
+
+* make sure every variable that is used is also defined
+ [ we don't really look at variable uses in detail.
+ 2.0 thing ]
+
+* make sure `missing' defines are generated
+
+* missing should handle install -d and rmdir -p (for uninstall)
+
+* NORMAL_INSTALL / NORMAL_UNINSTALL -vs- recursive rules
+ [ requires changes to the standard ]
+
+* should not put texiname_TEXINFOS into distribution
+ should rename this macro anyway, to foo_texi_DEPENDENCIES
+
+* For now I guess I'll just have automake give an error if it encounters
+non-C source in a libtool library specification.
+
+* if program has the same name as a target, do something sensible:
+ - if the target is internal, rename it
+ - if the target is mandated (eg, "info"), tell the user
+ consider auto-modifying the program name to work around this
+
+* should separate actual options from strictness levels
+ strictness should only cover requirements
+ You should be able to pick and choose options
+
+having just one Makefile for a project would give a big speed increase
+for a project with many directories, eg glibc. ideally (?) you'd
+still be able to have a Makefile.am in each directory somehow; this
+might make editing conceptually easier.
+
+* finish up TAGS work
+
+* only remove libtool at top level?
+
+* clean up source directory by moving stuff into subdirs
+
+* consider adding other variables similar to pkglibexecdir?
+ requests for pkg-dirs with version included
+
+Avoid loops when installing; instead unroll them in automake
+[ Impossible when @AC_SUBST@ values are used. ]
+
+Some long-term projects:
+* if $(FOO) is used somewhere, ensure FOO is defined, either by
+ user or by automake if possible
+
+[ include, += support ]
+* even better would be allowing targets in different included
+ fragments to be merged. e.g., `install-local'.
+
+consider putting all check-* targets onto @check?
+
+take diff-n-query code from libit
+
+Per Bothner says:
+Per> 1) Being able to build a set of non-source programs
+Per> from source programs, without necessarily linking them together.
+Per> I.e. one should be able to say something like:
+Per> dummy_SOURCES=foo.c bar.c
+Per> and automake should realize that it needs to build foo.o and bar.o.
+Per> 2) Being intelligent about new kinds of suffixes.
+Per> If it sees:
+Per> SUFFIXES = .class .java
+Per> and a suffix rule of the form:
+Per> .java.class:
+Per> then it should be able to realize it can build .class files from
+Per> .java files, and thus be able to generate a list of
+Per> .class files from a list of .java source files.
+[What Per wanted here was a way to have automate automatically follow
+suffix rules. So for instance if you had a `.x.y:' rule, and automake
+saw a `.x' file, it would automatically build and install the
+corresponding `.y' file.]
+
+Jim's idea: should look for @setfilename and warn if filenames too long
+* guess split size
+
+from joerg-martin schwarz:
+ -- If Makefile.am contains $(CC), $(COMPILE), $(YLWRAP), ....
+ in an explicitly written rule, you should emit the corresponding
+ Makefile variables automatically.
+
+From the GNU Standards. These things could be checked, and probably
+should be if --gnu.
+* Make sure that the directory into which the distribution unpacks (as
+well as any subdirectories) are all world-writable (octal mode 777).
+* Make sure that no file name in the distribution is more than 14
+characters long.
+* Don't include any symbolic links in the distribution itself.
+ (ditto hard links)
+* Make sure that all the files in the distribution are world-readable.
+
+should be able to determine what is built by looking at rules (and
+configure.in). Then built man pages (eg) could automatically be
+omitted from the distribution.
+
+Right now, targets generated internally (eg "install") are not
+overridable by user code. This should probably be possible, even
+though it isn't very important. This could be done by generating all
+internal rules via a function call instead of just appending to
+$output_rules.
+ [ this will be harder to implement when scanning a rule like all-recursive
+ from subdirs.am ]
+
+Other priorities:
+* Must rewrite am_install_var. Should break into multiple functions.
+ This will allow the callers to be a little smarter.
+* Rewrite clean targets.
+* Fix up require_file junk.
+
+djm wants ``LINKS'' variable; list of things to link together after
+install. In BSD environment, use:
+ LINKS = from1 to1 from2 to2 ...
+
+Need way to say there are no suffixes in a Makefile (Franc,ois'
+"override" idea suffices here)
+
+Check to make sure various scripts are executable (IE when looking for
+them in a directory)
+
+Add support for html via an option. Use texi2html. Use
+"html_TEXINFOS", and htmldir = .../html. Include html files in
+distribution. Also allow "html_DATA", for raw .html files.
+ [ when will texinfo directly support html? ]
+See also Karl Berry's message on a roadmap for a "info -> html"
+transition:
+<http://lists.gnu.org/archive/html/texinfo-devel/2012-03/msg00018.html>
+
+uninstall and pkg-dirs should rm -rf the dir.
+
+In general most .am files should be merged into automake. For
+instance all the "clean" targets could be merged by keeping lists of
+things to be removed. This would be a lot nicer looking. Note that
+the install targets probably should not be merged; it is sometimes
+useful to only install a small part.
+
+* Lex, yacc support:
+** It would be nice to automatically support using bison's better features
+ to rename the output files. This requires autoconf support
+** Consider supporting syntax from autoconf "derived:source", eg:
+ y.tab.c:perly.y
+ for yacc and lex source
+** what if you use flex and the option to avoid -lfl?
+ should support this?
+
+* Multi-language support:
+** should have mapping of file extensions to languages
+** should automatically handle the linking issue (special-case C++)
+** must get compile rules for various languages; FORTRAN probably
+ most important unimplemented language
+This should be integrated in some way with Per's idea.
+Eg .f.o rules should be recognized & auto-handled in _SOURCES
+That way any random language can be treated with C/C++ on a first-class
+basis (maybe)
+
+It might be cool to generate .texi dependencies by grepping for
+@include. (If done, it should be done the same way C dependencies are
+done)
+[ Ask Karl Berry for a -M option to makeinfo and texi2dvi? ]
+
+It would be good to check some parts of GNU standards. Already check
+for install-sh and mkinstalldirs. What else is required to be in
+package by GNU standards or by automake?
+Some things for --strictness=gnits:
+* "cd $(foo); something" is an error in a rule. Should be:
+ "cd $(foo) && something"
+* Look for 'ln -s' and warn about using $(LN_S) and AC_PROG_LN_S
+* Look for $(LN_S) and require AC_PROG_LN_S
+
+Auto-distribute "ChangeLog.[0-9]+"? "ChangeLog.[a-z]+"?
+
+Check all source files to make sure that FSF address is up-to-date.
+--gnits or --gnu only.
+
+Merge each -vars.am file with corresponding ".am" file. Can do this
+because of changes to &file_contents.
+
+Should libexec programs have the name transform done on them?
+
+Order the output rules sensibly, so FOO_SOURCES and FOO_OBJECTS are
+together and rules are in the usual order.
+
+djm says:
+David> To avoid comments like the one about subdirs getting buried in
+David> the middle of a Makefile.in, how about pushing comments that
+David> start with ### to the top of the Makefile.in (in order)? Sort
+David> of like how Autoconf uses diversions to force initialization

+
+Libraries:

+
+================================================================
+
+Longer term:
+
+Would it be useful to integrate in some way with the Debian package
+building utility? Must check. maybe it would be possible to deal
+with all the different package utilities somehow. Lately I've been
+hearing good things about the RedHat packaging utilities. Why are
+there so many of these? Are they fun to write or something?
+The RedHat package utility is called RPM; see
+ ftp://ftp.redhat.com/pub/code/rpm
+It actually has problems, like no configure script and no documentation.
+
+For Cygnus it would probably be good to be able to handle the native
+package utility on each platform. There are probably 3 or 4 of these
+(sysv, solaris?, aix?)
+
+tcl/unix/Makefile.in has some code to generate a Solaris package.
+
+Automake probably can't do all of this on its own. A new tool might
+be a better idea
+
+I have some notes from a Debian developer on how the integration
+should work
+
+================================================================
+
+A tool to guess what the local Makefile.am should look like:
+(see Gord's Maint program!)
+
+* Probably integrate with autoscan
+* Use various simple rules to determine what to do:
+ * get name of top directory, sans version info
+ * search for .c files with 'main' in them
+ * if in main.c, use directory name for program
+ * if in more than one, generate multiple programs
+ * if not found, generate a library named after directory
+ * order subdir searches correctly: lib first, src last
+ * assume 'testsuite' dir means we are using dejagnu
+* maybe be smart about reading existing Makefile.am, so tool
+ can be run for incremental changes? You could imagine:
+
+ Makefile.am:
+ autoproject --incremental
+
+================================================================
+
+Stuff NOT to do, and why:
+
+consider auto-including any file that matches "*.in".
+ [ no: po/Makefile.in shouldn't be included ]
+
+must look at mkid to see how it works (for subdir usage)
+ [ right now, it doesn't. i don't see a simple fix right now ]
+
+if configure.in not found, move up a directory and try again? This
+could eliminate a common source of problems.
+ [ this is just a bad idea ]
+
+* scripts are installed in $exec_prefix/bin, not $prefix/bin
+ Bug or feature?
+ [ the consensus on Gnits is that this isn't required.
+ doubters can work around it anyway ]
+
+Scan source directories and warn about missing files, eg .c/.h files
+that aren't mentioned?
+ [ distcheck makes this less useful ]
+
+* quoting bugs
+ - how to install file with a space in its name?
+ [ don't bother with this -- make is just too losing ]
+
+* notice when a .c file is a target somewhere, and auto-add it to
+ BUILT_SOURCES
+ [ BUILT_SOURCES are for files that need to be built before anything
+ else because of hidden dependencies (something .c files are
+ unlikely to be) ]
+
+* Scan multiple input files when Makefile is generated?
+ This would provide flexibility for large projects; subsumes
+ the "Makefile.tmpl" idea
+ [ can't do this. must explain why in manual.
+ basically, solving all the problems is too hard
+ like: how to remove redundancies between generated .in files
+ instead should implement `include' directive for Makefile.am ]
+
+* Should be a way to have "nobuild_PROGRAMS" which aren't even built,
+ but which could be by running the magic make command.
+ [ We already have EXTRA_PROGRAMS for this. ]

+ The Automake test suite
+
+
+User interface
+==============
+
+
+Running the tests
+-----------------
+
+ To run all tests:
+
+ make -k check
+
+ By default, verbose output of a test 't/foo.sh' or 't/foo.tap' is retained
+ in the log file 't/foo.log'. Also, a summary log is created in the file
+ 'test-suite.log' (in the top-level directory).
+
+ You can use '-jN' for faster completion (it even helps on a uniprocessor
+ system, due to unavoidable sleep delays, as noted below):
+
+ make -k -j4
+
+ To rerun only failed tests:
+
+ make -k recheck
+
+ To run only tests that are newer than their last results:
+
+ make -k check RECHECK_LOGS=
+
+ To run only selected tests:
+
+ make -k check TESTS="t/foo.sh t/bar.tap" (GNU make)
+ env TESTS="t/foo.sh t/bar.tap" make -e -k check (non-GNU make)
+
+ To run the tests in cross-compilation mode, you should first configure
+ the automake source tree to a cross-compilation setup. For example, to
+ run with a Linux-to-MinGW cross compiler, you will need something like
+ this:
+
+ ./configure --host i586-mingw32msvc --build i686-pc-linux-gnu
+
+ To avoid possible spurious error, you really have to *explicitly* specify
+ '--build' in addition to '--host'; the 'lib/config.guess' script can help
+ determine the correct value to pass to '--build'.
+ Then you can just run the testsuite in the usual way, and the test cases
+ using a compiler should automatically use a cross-compilation setup.
+
+
+Interpretation
+--------------
+
+ Successes:
+ PASS - success
+ XFAIL - expected failure
+
+ Failures:
+ FAIL - failure
+ XPASS - unexpected success
+
+ Other:
+ SKIP - skipped tests (third party tools not available)
+ ERROR - some unexpected error condition
+
+
+About the tests
+---------------
+
+ There are two kinds of tests in the Automake testsuite (both implemented
+ as shell scripts). The scripts with the '.sh' suffix are "simple"
+ tests, their outcome completely determined by their exit status. Those
+ with the '.tap' suffix use the TAP protocol. If you want to run a test
+ by hand, you can do so directly if it is a simple test:
+
+ ./t/nogzip.sh
+
+ (it will be verbose by default), while if it is a TAP test you can pass
+ it to your preferred TAP runner, as in e.g.:
+
+ prove --verbose --merge ./t/add-missing.tap
+
+ The tests can also be run directly in a VPATH build, as with:
+
+ /path/to/srcdir/t/nogzip.sh
+ prove --verbose --merge /path/to/srcdir/t/add-missing.tap
+
+
+Supported shells
+----------------
+
+ By default, the tests are run by the $SHELL detected at configure
+ time. They also take care to re-execute themselves with that shell,
+ unless told not to. So, to run the tests with a different shell, say
+ '/path/to/another/sh', the user must use:
+
+ AM_TESTS_REEXEC=no /path/to/another/sh ./t/foo.sh
+ AM_TESTS_REEXEC=no prove -v -e /path/to/another/sh ./t/bar.tap
+
+ to run a test directly, and:
+
+ make check LOG_COMPILER=/path/to/sh (GNU make)
+ LOG_COMPILER=/path/to/sh make -e check (non-GNU make)
+
+ to run the test(s) through the makefile test driver.
+
+ The test scripts are written with portability in mind, so that they
+ should run with any decent Bourne-compatible shell.
+
+ However, some care must be used with Zsh, since, when not directly
+ started in Bourne-compatibility mode, it has some incompatibilities
+ in the handling of $0 which conflict with our usage. Our testsuite
+ can automatically work around these incompatibilities when a version
+ 4.3 or later of Zsh is used, but unfortunately not when an older
+ version of Zsh is used. Thus, if you want to run a test script, say
+ 'foo.sh', with Zsh 4.2, you *can't* simply do "zsh foo.sh", but
+ you *must* resort to:
+
+ AM_TESTS_REEXEC=no zsh -o no_function_argzero foo.sh
+
+ Note that this problem does not occur if Zsh is executed through
+ a symlink with a basename of 'sh', since in that case Zsh starts
+ in Bourne compatibility mode. So you should be perfectly safe
+ when /bin/sh is Zsh, even a it's version < 4.3.
+
+
+Reporting failures
+------------------
+
+ Send verbose output, i.e., the contents of test-suite.log, of failing
+ tests to <bug-automake@gnu.org>, along with the usual version numbers
+ (which Automake, which Autoconf, which operating system, which make
+ version, which shell, etc.)
+
+
+
+Writing test cases
+==================
+
+
+Do
+--
+
+ If you plan to fix a bug, write the test case first. This way you'll
+ make sure the test catches the bug, and that it succeeds once you have
+ fixed the bug.
+
+ Add a copyright/license paragraph.
+
+ Explain what the test does.
+
+ Cite the PR number (if any), and the original reporter (if any), so
+ we can find or ask for information if needed.
+
+ If a test checks examples or idioms given in the documentation, make
+ sure the documentation reference them appropriately in comments, as in:
+ @c Keep in sync with autodist-config-headers.sh
+ @example
+ ...
+ @end example
+
+ Use "required=..." for required tools. Do not explicitly require
+ tools which can be taken for granted because they're listed in the
+ GNU Coding Standards (for example, 'gzip').
+
+ Include ./defs in every test script (see existing tests for examples
+ of how to do this).
+
+ Use the 'skip_' function to skip tests, with a meaningful message if
+ possible. Where convenient, use the 'warn_' function to print generic
+ warnings, the 'fail_' function for test failures, and the 'fatal_'
+ function for hard errors. In case a hard error is due to a failed
+ set-up of a test scenario, you can use the 'framework_fail_' function
+ instead.
+
+ For those tests checking the Automake-provided test harnesses that are
+ expected to work also when the 'serial-tests' Automake option is used
+ (thus causing the serial testsuite harness to be used in the generated
+ Makefile), place a line containing "try-with-serial-tests" somewhere
+ in the file. That will ensure that the 'gen-testsuite-part' script
+ generates a sibling of that test which uses the serial harness instead
+ of the parallel one. For those tests that are *not* meant to work with
+ the parallel testsuite harness at all (these should be very very few),
+ set the shell variable 'am_serial_tests' to "yes" before including
+ ./defs.
+
+ Some tests in the Automake testsuite are auto-generated; those tests
+ might have custom extensions, but their basename (that is, with such
+ extension stripped) is expected to end with "-w" string, optionally
+ followed by decimal digits. For example, the name of a valid
+ auto-generated test can be 'color-w.sh' or 'tap-signal-w09.tap'.
+ Please don't name hand-written tests in a way that could cause them
+ to be confused with auto-generated tests; for example, 'u-v-w.sh'
+ or 'option-w0.tap' are *not* valid name for hand-written tests.
+
+ ./defs brings in some commonly required files, and sets a skeleton
+ configure.ac. If possible, append to this file. In some cases
+ you'll have to overwrite it, but this should be the exception. Note
+ that configure.ac registers Makefile.in but do not output anything by
+ default. If you need ./configure to create Makefile, append AC_OUTPUT
+ to configure.ac. In case you don't want ./defs to pre-populate your
+ test directory (which is a rare occurrence), set the 'am_create_testdir'
+ shell variable to "empty" before sourcing ./defs.
+
+ By default, the testcases are run with the errexit shell flag on,
+ to make it easier to catch failures you might not have thought of.
+ If this is undesirable in some testcase, you can use "set +e" to
+ disable the errexit flag (but please do so only if you have a very
+ good reason).
+
+ End the test script with a ":" or "Exit 0". Otherwise, when somebody
+ changes the test by adding a failing command after the last command,
+ the test will spuriously fail because $? is nonzero at the end. Note
+ that this is relevant even if the errexit shell flag is on, in case
+ the test contains commands like "grep ... Makefile.in && Exit 1" (and
+ there are indeed a lot of such tests).
+
+ Use $ACLOCAL, $AUTOMAKE, $AUTOCONF, $AUTOUPDATE, $AUTOHEADER,
+ $PERL, $MAKE, $EGREP, and $FGREP, instead of the corresponding
+ commands.
+
+ Use $sleep when you have to make sure that some file is newer
+ than another.
+
+ Use cat or grep or similar commands to display (part of) files that
+ may be interesting for debugging, so that when a user send a verbose
+ output we don't have to ask him for more details. Display stderr
+ output on the stderr file descriptor. If some redirected command is
+ likely to fail, display its output even in the failure case, before
+ exiting.
+
+ Use 'Exit' rather than 'exit' to abort for leave early from a test
+ case.
+
+ Use '$PATH_SEPARATOR', not hard-coded ':', as the separator of
+ PATH's entries.
+
+ It's more important to make sure that a feature works, than make
+ sure that Automake's output looks correct. It might look correct
+ and still fail to work. In other words, prefer running 'make' over
+ grepping Makefile.in (or do both).
+
+ If you run $ACLOCAL, $AUTOMAKE or $AUTOCONF several times in the
+ same test and change configure.ac by the meantime, do
+ rm -rf autom4te*.cache
+ before the following runs. On fast machines the new configure.ac
+ could otherwise have the same timestamp as the old autom4te.cache.
+
+ Use filenames with two consecutive spaces when testing that some
+ code preserves filenames with spaces. This will catch errors like
+ `echo $filename | ...`.
+
+ Make sure your test script can be used to faithfully check an
+ installed version of automake (as with "make installcheck"). For
+ example, if you need to copy or grep an automake-provided script,
+ do not assume that they can be found in the '$top_srcdir/lib'
+ directory, but use '$am_scriptdir' instead. The complete list of
+ such "$am_...dir" variables can be found in the 'defs-static.in'
+ file.
+
+ When writing input for lex, include the following in the definitions
+ section:
+ %{
+ #define YY_NO_UNISTD_H 1
+ %}
+ to accommodate non-ANSI systems, since GNU flex generates code that
+ includes unistd.h otherwise. Also add:
+ int isatty (int fd) { return 0; }
+ to the definitions section if the generated code is to be compiled
+ by a C++ compiler, for similar reasons (i.e., the isatty(3) function
+ from that same unistd.h header would be required otherwise).
+
+ Before commit: make sure the test is executable, add the tests to
+ TESTS in Makefile.am, add it to XFAIL_TESTS in addition if needed,
+ write a ChangeLog entry, send the diff to <automake-patches@gnu.org>.
+
+
+Do not
+------
+
+ Do not test an Automake error with "$AUTOMAKE && Exit 1", or in three
+ years we'll discover that this test failed for some other bogus reason.
+ This happened many times. Better use something like
+ AUTOMAKE_fails
+ grep 'expected diagnostic' stderr
+ (Note this doesn't prevent the test from failing for another reason,
+ but at least it makes sure the original error is still here).
+
+ Do not override Makefile variables using make arguments, as in e.g.:
+ $MAKE prefix=/opt install
+ This is not portable for recursive targets (targets that call a
+ sub-make may not pass "prefix=/opt" along). Use the following
+ instead:
+ prefix=/opt $MAKE -e install

+# Ensure 'make dist' fails when help2man replacement man pages are created.
+#
+# The assumption here is the following: if the developer uses help2man to
+# generate man pages from --help output, then these man pages may not be
+# stored in VCS. However, they should be distributed, so that the end user
+# that receives the tarball doesn't have to install help2man. If they are
+# not distributed, then the developer should make help2man a prerequisite
+# to building the package from a tarball, e.g., with a configure check for
+# help2man that errors out if it is unavailable. In both cases it is
+# sufficient to check only distributed man pages.
+#
+# Idea of this whole shenanigan is to allow somebody to check out sources from
+# a VCS and build and install them without needing help2man installed. The
+# installed man pages will be bogus in this case. Typically, this happens
+# when developers ask users to try out a fix from VCS; the developers themselves
+# will usually have help2man installed (or should install it).

+# The dashmstdout depmode calls libtool in parallel to generate the
+# dependencies (with -M flag) and to build the objfile (both have
+# --mode=compile and -o).
+# The process with 'libtool --mode=compile .* -M' can corrupt the objfile
+# as none is generated by the compiler. Since --mode=compile and -o are
+# set libtool assumes that a objfile should be generated and will execute
+# invalid $mv & $LN_S.
+#
+# == Fix ==
+# Now 'depcomp' never compute dependencies in the background, as this can
+# cause races with libtool. Compute the dependencies after the actual
+# compilation.

+'configure' configures GNU coreutils 8.14a to adapt to many kinds of systems.
+
+Usage: ./configure [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print 'checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for '--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or '..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [/usr/local]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, 'make install' will install all the files in
+'/usr/local/bin', '/usr/local/lib' etc. You can specify
+an installation prefix other than '/usr/local' using '--prefix',
+for instance '--prefix=$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]
+ --sbindir=DIR system admin executables [EPREFIX/sbin]
+ --libexecdir=DIR program executables [EPREFIX/libexec]
+ --sysconfdir=DIR read-only single-machine data [PREFIX/etc]
+ --sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
+ --localstatedir=DIR modifiable single-machine data [PREFIX/var]
+ --libdir=DIR object code libraries [EPREFIX/lib]
+ --includedir=DIR C header files [PREFIX/include]
+ --oldincludedir=DIR C header files for non-gcc [/usr/include]
+ --datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
+ --datadir=DIR read-only architecture-independent data [DATAROOTDIR]
+ --infodir=DIR info documentation [DATAROOTDIR/info]
+ --localedir=DIR locale-dependent data [DATAROOTDIR/locale]
+ --mandir=DIR man documentation [DATAROOTDIR/man]
+ --docdir=DIR documentation root [DATAROOTDIR/doc/coreutils]
+ --htmldir=DIR html documentation [DOCDIR]
+ --dvidir=DIR dvi documentation [DOCDIR]
+ --pdfdir=DIR pdf documentation [DOCDIR]
+ --psdir=DIR ps documentation [DOCDIR]
+
+Program names:
+ --program-prefix=PREFIX prepend PREFIX to installed program names
+ --program-suffix=SUFFIX append SUFFIX to installed program names
+ --program-transform-name=PROGRAM run sed PROGRAM on installed program names
+
+System types:
+ --build=BUILD configure for building on BUILD [guessed]
+ --host=HOST cross-compile to build programs to run on HOST [BUILD]
+
+Optional Features:
+ --disable-option-checking ignore unrecognized --enable/--with options
+ --disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
+ --enable-FEATURE[=ARG] include FEATURE [ARG=yes]
+ --enable-silent-rules less verbose build output (undo: 'make V=1')
+ --disable-silent-rules verbose build output (undo: 'make V=0')
+ --disable-dependency-tracking speeds up one-time build
+ --enable-dependency-tracking do not reject slow dependency extractors
+ --disable-largefile omit support for large files
+ --enable-threads={posix|solaris|pth|win32}
+ specify multithreading API
+ --disable-threads build without multithread safety
+ --disable-acl do not support ACLs
+ --disable-assert turn off assertions
+ --disable-rpath do not hardcode runtime library paths
+ --disable-xattr do not support extended attributes
+ --disable-libcap disable libcap support
+ --enable-gcc-warnings turn on lots of GCC warnings (for developers)
+ --enable-install-program=PROG_LIST
+ install the programs in PROG_LIST (comma-separated,
+ default: none)
+ --enable-no-install-program=PROG_LIST
+ do NOT install the programs in PROG_LIST
+ (comma-separated, default: arch,hostname,su)
+ --disable-nls do not use Native Language Support
+
+Optional Packages:
+ --with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
+ --without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
+ --with-gnu-ld assume the C compiler uses GNU ld default=no
+ --with-libiconv-prefix[=DIR] search for libiconv in DIR/include and DIR/lib
+ --without-libiconv-prefix don't search for libiconv in includedir and libdir
+ --with-libpth-prefix[=DIR] search for libpth in DIR/include and DIR/lib
+ --without-libpth-prefix don't search for libpth in includedir and libdir
+ --without-included-regex
+ don't compile regex; this is the default on systems
+ with recent-enough versions of the GNU C Library
+ (use with caution on other systems).
+ --without-selinux do not use SELinux, even on systems with SELinux
+ --with-packager String identifying the packager of this software
+ --with-packager-version Packager-specific version information
+ --with-packager-bug-reports
+ Packager info for bug reports (URL/e-mail/...)
+ --with-tty-group[=NAME]
+ group used by system for TTYs, "tty" when not
+ specified (default: do not rely on any group used
+ for TTYs)
+ --without-gmp do not use the GNU MP library for arbitrary
+ precision calculation (default: use it if available)
+ --with-libintl-prefix[=DIR] search for libintl in DIR/include and DIR/lib
+ --without-libintl-prefix don't search for libintl in includedir and libdir
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ YACC The "Yet Another C Compiler" implementation to use. Defaults to
+ 'bison -y'. Values other than 'bison -y' will most likely break
+ on most systems.
+ YFLAGS YFLAGS contains the list arguments that will be passed by
+ default to Bison. This script will default YFLAGS to the empty
+ string to avoid a default value of '-d' given by some make
+ applications.
+ DEFAULT_POSIX2_VERSION
+ POSIX version to default to; see 'config.hin'.
+
+Use these variables to override the choices made by 'configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# | Thu Nov 23 18:02:38 1995 Tom Tromey <tromey@cambric>
+# | [ ... ]
+# | * subdirs.am: Removed "::" rules

+# | Removed "::" rules
+# | * scripts.am, programs.am, libprograms.am: Removed "::" rules

+
+# On a related topic, the Autoconf manual has the following text:
+# | 'VPATH' and double-colon rules
+# | Any assignment to 'VPATH' causes Sun 'make' to only execute
+# | the first set of double-colon rules. (This comment has been
+# | here since 1994 and the context has been lost. It's probably
+# | about SunOS 4. If you can reproduce this, please send us a

+# We already know that overlapping ::-rule like
+#
+# a :: b
+# echo rule1 >> $@
+# a :: c
+# echo rule2 >> $@
+# a :: b c
+# echo rule3 >> $@
+#
+# do not work equally on all platforms. It seems that in all cases
+# Make attempts to run all matching rules. However at least GNU Make,
+# NetBSD Make, and FreeBSD Make will detect that $@ was updated by the
+# first matching rule and skip remaining matches (with the above
+# example that means that unless 'a' was declared PHONY, only "rule1"
+# will be appended to 'a' if both b and c have changed). Other
+# implementations like OSF1 Make and HP-UX Make do not perform such a
+# check and execute all matching rules whatever they do ("rule1",
+# "rule2", abd "rule3" will all be appended to 'a' if b and c have
+# changed).
+
+# So it seems only non-overlapping ::-rule may be portable. This is
