3 * Miscellaneous changes:
5 - The `lzma' compression scheme and associated automake option `dist-lzma'
6 is obsoleted by `xz' and `dist-xz' due to upstream changes.
10 * Bugs introduced by 1.11:
12 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
13 trailing white space in the test list (`TESTS = foo $(EMPTY)').
15 - The `silent-rules' option now also silences all compile rules if dependency
16 tracking is disabled. Also, when `silent-rules' is not used, the output from
17 `make' does not contain spurious extra lines with only a backslash in them
18 any more; it now again matches that from pre-1.11 Automake.
20 - The `dist-xz' option now uses `xz -9' for maximum compression.
22 - The AM_COND_IF macro also works if the shell expression for the conditional
23 is no longer valid for the condition.
27 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
28 even if the `--prefix' argument pointed outside of a system directory.
29 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
30 `get_python_lib' function if it points outside the configured prefix,
31 unless the `--prefix' argument was either `/usr' or below `/System'.
33 - The testsuite does not try to change the mode of `ltmain.sh' files from
34 a Libtool installation (symlinked to test directories) any more.
36 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
37 tools are preferred in a cross-compile setup.
39 - Several scripts as well as the parallel-tests testsuite driver now
40 exit with the right exit status upon receiving a signal.
42 - A per-Makefile.am setting of -Werror does not carry over to the
43 handling of other Makefile.am files any more.
45 - The order of Yacc and Lex flags is fixed to be consistent with other
46 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
47 $(LFLAGS), so that the user variables override the developer variables.
49 - Rules generated by Automake now try harder to not change any files when
50 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
51 Yacc source files and the rule to update config.h.
53 - The code for automatic dependency tracking works around a Solaris
54 make bug triggered by sources containing repeated slashes when the
55 `subdir-objects' option was used.
59 * Version requirements:
61 - Autoconf 2.62 or greater is required.
65 - The autoconf version check implemented by aclocal in aclocal.m4
66 (and new in Automake 1.10) is degraded to a warning. This helps
67 in the common case where the Autoconf versions used are compatible.
69 * Changes to automake:
71 - The automake program can run multiple threads for creating most
72 Makefile.in files concurrently, if at least Perl 5.7.2 is available
73 with interpreter-based threads enabled. Set the environment variable
74 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
75 enable this experimental feature.
77 * Changes to Libtool support:
79 - Libtool generic flags are now passed to the install and uninstall
82 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
83 config.lt is removed correctly now.
87 - subdir-object mode works now with Fortran (F77, FC, preprocessed
90 - For files with extension .f90, .f95, .f03, or .f08, the flag
91 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
93 - Files with extension .sx are also treated as preprocessed assembler.
95 - The default source file extension (.c) can be overridden with
96 AM_DEFAULT_SOURCE_EXT now.
98 - Python 3.0 is supported now, Python releases prior to 2.0 are no
101 - AM_PATH_PYTHON honors python's idea about the site directory.
103 - There is initial support for the Vala programming language, when using
106 * Miscellaneous changes:
108 - Automake development is done in a git repository on Savannah now, see
110 http://git.sv.gnu.org/gitweb/?p=automake.git
112 A read-only CVS mirror is provided at
114 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
115 checkout -d automake HEAD
117 - "make dist" can now create xz-compressed tarballs,
118 as well as (deprecated?) lzma-compressed tarballs.
120 - `automake --add-missing' will by default install the GPLv3 file as
121 COPYING if it is missing. It will also warn that the license file
122 should be added to source control. Note that Automake will never
123 overwrite an existing COPYING file, even when the `--force-missing'
126 - The manual is now distributed under the terms of the GNU FDL 1.3.
128 - Automake ships and installs man pages for automake and aclocal now.
130 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
132 - install-sh supports -C, which does not update the installed file
133 (and its time stamps) if the contents did not change.
135 - The `gnupload' script has been revamped.
137 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
139 - The targets `install' and `uninstall' are more efficient now, in that
140 for example multiple files from one Automake variable such as
141 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
142 invocation if they do not have to be renamed.
144 Both install and uninstall may sometimes enter (`cd' into) the target
145 installation directory now, when no build-local scripts are used.
147 Both install and uninstall do not fail anymore but do nothing if an
148 installation directory variable like `bindir' is set to the empty string.
150 For built-in rules, `make install' now fails reliably if installation
151 of a file failed. Conversely, `make uninstall' even succeeds when
152 issued multiple times.
154 These changes may need some adjustments from users: For example,
155 some `install' programs refuse to install multiple copies of the
156 same file in one invocation, so you may need to remove duplicate
157 entries from file lists.
159 Also, within one set of files, say, nobase_data_DATA, the order of
160 installation may be changed, or even unstable among different hosts,
161 due to the use of associative arrays in awk. The increased use of
162 awk matches a similar move in Autoconf to provide for better scaling.
164 Further, most undocumented per-rule install command variables such as
165 binSCRIPT_INSTALL have been removed because they are not needed any
166 more. Packages which use them should be using the appropriate one of
167 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
168 counterpart, depending on the type of files and the need for automatic
169 target directory creation.
171 - The "deleted header file problem" for *.m4 files is avoided by
172 stub rules. This allows `make' to trigger a rerun of `aclocal'
173 also if some previously needed macro file has been removed.
175 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
176 an otherwise up to date tree.
178 - The `color-tests' option causes colored test result output on terminals.
180 - The `parallel-tests' option enables a new test driver that allows for
181 parallel test execution, inter-test dependencies, lazy test execution
182 for unit-testing, re-testing only failed tests, and formatted result output
183 as RST (reStructuredText) and HTML. Enabling this option may require some
184 changes to your test suite setup; see the manual for details.
186 - The `silent-rules' option enables Linux kernel-style silent build output.
187 This option requires the widely supported but non-POSIX `make' feature
188 of recursive variable expansion, so do not use it if your package needs
189 to build with `make' implementations that do not support it.
191 To enable less verbose build output, the developer has to use the Automake
192 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
193 macro. The user may then set the default verbosity by passing the
194 `--enable-silent-rules' option to `configure'. At `make' run time, this
195 default may be overridden using `make V=0' for less verbose, and `make V=1'
196 for backward-compatible verbose output.
198 - New prefix `notrans_' for manpages which should not be transformed
199 by --program-transform.
201 - New macro AM_COND_IF for conditional evaluation and conditional
204 - For AC_CONFIG_LINKS, if source and destination are equal, do not
205 remove the file in a non-VPATH build. Such setups work with Autoconf
208 - AM_MAINTAINER_MODE now allows for an optional argument specifying
211 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
212 useful especially for multi-line values.
214 - Automake's early configure-time sanity check now diagnoses an
215 unsafe absolute source directory name and makes configure fail.
217 - The Automake macros and rules cope better with whitespace in the
218 current directory name, as long as the relative path to `configure'
219 does not contain whitespace. To this end, the values of `$(MISSING)'
220 and `$(install_sh)' may contain suitable quoting, and their expansion
221 might need `eval'uation if used outside of a makefile. These
222 undocumented variables may be used in several documented macros such
223 as $(AUTOCONF) or $(MAKEINFO).
227 * Long standing bugs:
229 - Fix aix dependency tracking for libtool objects.
231 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
232 unnecessary use of the `compile' script.
234 - For nobase_*_LTLIBRARIES with nonempty directory components, the
235 correct `-rpath' argument is used now.
237 - `config.status --file=Makefile depfiles' now also works with the
238 extra quoting used internally by Autoconf 2.62 and newer
239 (it used to work only without the `--file=' bit).
241 - The `missing' script works better with versioned tool names.
243 - Semantics for `missing help2man' have been revamped:
245 Previously, if `help2man' was not present, `missing help2man' would have
246 the following semantics: if some man page was out of date but present, then
247 a warning would be printed, but the exit status was 0. If the man page was
248 not present at all, then `missing' would create a replacement man page
249 containing an error message, and exit with a status of 2. This does not play
250 well with `make': the next run will see this particular man page as being up
251 to date, and will only error out on the next generated man page, if any;
252 repeat until all pages are done. This was not desirable.
254 These are the new semantics: if some man page is not present, and help2man
255 is not either, then `missing' will warn and generate the replacement page
256 containing the error message, but exit successfully. However, `make dist'
257 will ensure that no such bogus man pages are packaged into a tarball.
259 - Targets provided by automake behave better with `make -n', in that they
260 take care not to create files.
262 - `config.status Makefile... depfiles' works fine again in the presence of
263 disabled dependency tracking.
265 - The default no-op recursive rules for these targets also work with BSD make
266 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
268 - `make distcheck' works also when both a directory and some file below it
269 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
271 - Texinfo dvi, ps, pdf, and html output files are not removed upon
272 `make mostlyclean' any more; only the LaTeX by-products are.
274 - Renamed objects also work with the `subdir-objects' option and
275 source file languages which Automake does not know itself.
277 - `automake' now correctly complains about variable assignments which are
278 preceded by a comment, extend over multiple lines with backslash-escaped
279 newlines, and end in a comment sign. Previous versions would silently
280 and wrongly ignore such assignments completely.
282 * Bugs introduced by 1.10:
284 - Fix output of dummy dependency files in presence of post-processed
285 Makefile.in's again, but also cope with long lines.
287 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
288 that have been declared as programs in the same Makefile.
289 This is for consistency with the analogous change to TESTS in 1.10.
291 - Fix order of standard includes to again be `-I. -I$(srcdir)',
292 followed by directories containing config headers.
296 * Version requirements:
298 - Autoconf 2.60 or greater is required.
300 - Perl 5.6 or greater is required.
302 * Changes to aclocal:
304 - aclocal now also supports -Wmumble and -Wno-mumble options.
306 - `dirlist' entries (for the aclocal search path) may use shell
307 wildcards such as `*', `?', or `[...]'.
309 - aclocal supports an --install option that will cause system-wide
310 third-party macros to be installed in the local directory
311 specified with the first -I flag. This option also uses #serial
312 lines in M4 files to upgrade local macros.
314 The new aclocal options --dry-run and --diff help to review changes
315 before they are installed.
317 - aclocal now outputs an autoconf version check in aclocal.m4 in
318 projects using automake.
320 For a few years, automake and aclocal have been calling autoconf
321 (or its underlying engine autom4te) to accurately retrieve the
322 data they need from configure.ac and its siblings. Doing so can
323 only work if all autotools use the same version of autoconf. For
324 instance a Makefile.in generated by automake for one version of
325 autoconf may stop working if configure is regenerated with another
326 version of autoconf, and vice versa.
328 This new version check ensures that the whole build system has
329 been generated using the same autoconf version.
331 * Support for new Autoconf macros:
333 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
335 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
336 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
337 in different directories. However, only one instance of such a
338 library objects directory is supported.
340 * Change to Libtool support:
342 - Libtool generic flags (those that go before the --mode=MODE option)
343 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
345 * Yacc and Lex changes:
347 - The rebuild rules for distributed Yacc and Lex output will avoid
348 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
351 - ylwrap is now always used for lex and yacc source files,
352 regardless of whether there is more than one source per directory.
356 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
357 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
358 tracking, unlike non-preprocessed assembler (*.s).
360 - subdir-object mode works now with Assembler. Automake assumes
361 that the compiler understands `-c -o'.
363 - Preprocessed assembler (*.S) compilation now also honors
364 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
366 - Improved support for Objective C:
367 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
368 - A new section of the manual documents the support.
370 - New support for Unified Parallel C:
371 - AM_PROG_UPC looks for a UPC compiler.
372 - A new section of the manual documents the support.
374 - Per-target flags are now correctly handled in link rules.
376 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
377 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
378 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
379 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
381 The fix for compiler flags (i.e., using maude_CFLAGS instead of
382 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
383 is expected to work (and actually works during compilation).
385 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
386 "in addition to" breaks backward compatibility with older versions.
387 If your package used both variables, as in
389 AM_LDFLAGS = common flags
391 a_LDFLAGS = more flags
394 and assumed *_LDFLAGS would sum up, you should rewrite it as
396 AM_LDFLAGS = common flags
398 a_LDFLAGS = $(AM_LDFLAGS) more flags
401 This new behavior of *_LDFLAGS is more coherent with other
402 per-target variables, and the way *_LDFLAGS variables were
403 considered internally.
405 * New installation targets:
407 - New targets mandated by GNU Coding Standards:
412 By default they will only install Texinfo manuals.
413 You can customize them with *-local variants:
419 - The undocumented recursive target `uninstall-info' no longer exists.
420 (`uninstall' is in charge of removing all possible documentation
421 flavors, including optional formats such as dvi, ps, or info even
422 when `no-installinfo' is used.)
424 * Miscellaneous changes:
426 - Automake no longer complains if input files for AC_CONFIG_FILES
427 are specified using shell variables.
429 - clean, distribution, or rebuild rules are normally disabled for
430 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
431 AC_CONFIG_LINK specified using shell variables. However, if these
432 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
433 be able to output rules anyway.
434 (See the Automake documentation for AC_CONFIG_FILES.)
436 - $(EXEEXT) is automatically appended to filenames of TESTS
437 that have been declared as programs in the same Makefile.
438 This is mostly useful when some check_PROGRAMS are listed in TESTS.
440 - `-Wportability' has finally been turned on by default for `gnu' and
441 `gnits' strictness. This means, automake will complain about %-rules
442 or $(GNU Make functions) unless you switch to `foreign' strictness or
443 use `-Wno-portability'.
445 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
446 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
447 $(mkdir_p) variable is still defined (to the same value as
448 $(MKDIR_P)) but should be considered obsolete. If you are using
449 $(mkdir_p) in some of your rules, please plan to update them to
450 $(MKDIR_P) at some point.
452 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
453 They still work in this release, but may be withdrawn in a future one.
455 - Inline compilation rules for gcc3-style dependency tracking are
458 - Automake installs a "Hello World!" example package in $(docdir).
459 This example is used throughout the new "Autotools Introduction"
460 chapter of the manual.
464 * Makefile.in bloat reduction:
466 - Inference rules are used to compile sources in subdirectories when
467 the `subdir-objects' option is used and no per-target flags are
468 used. This should reduce the size of some projects a lot, because
469 Automake used to output an explicit rule for each such object in
472 - Automake no longer outputs three rules (.o, .obj, .lo) for each
473 object that must be built with explicit rules. It just outputs
474 the rules required to build the kind of object considered: either
475 the two .o and .obj rules for usual objects, or the .lo rule for
478 * Change to Libtool support:
480 - Libtool tags are used with libtool versions that support them.
481 (I.e., with Libtool 1.5 or greater.)
483 - Automake is now able to handle setups where a libtool library is
484 conditionally installed in different directories, as in
487 lib_LTLIBRARIES = liba.la
489 pkglib_LTLIBRARIES = liba.la
491 liba_la_SOURCES = ...
493 * Changes to aclocal:
495 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
496 really evaluated, before it decides to include them in aclocal.m4.
497 This solves nasty problems with conditional redefinitions of
498 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
499 *.m4 files to be included in any project using these macros.
500 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
501 most famous instance of this bug.)
503 - Do not complain about missing conditionally AC_REQUIREd macros
504 that are not actually used. In 1.8.x aclocal would correctly
505 determine which of these macros were really needed (and include
506 only these in the package); unfortunately it would also require
507 all of them to be present in order to run. This created
508 situations were aclocal would not work on a tarball distributing
509 all the macros it uses. For instance running aclocal on a project
510 containing only the subset of the Gettext macros in use by the
511 project did not work, because gettext conditionally requires other
514 * Portability improvements:
516 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
517 tar-pax. The new option filename-length-max=99 helps diagnosing
518 filenames that are too long for tar-v7. (PR/414)
520 - Variables aumented with `+=' are now automatically flattened (i.e.,
521 trailing backslashes removed) and then wrapped around 80 colummns
522 (adding trailing backslashes). In previous versions, a long series
528 would result in a single-line definition of VAR that could possibly
529 exceed the maximum line length of some make implementations.
531 Non-augmented variables are still output as they are defined in
536 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
537 Works the same as the old Fortran 77 implementation; just replace
538 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
539 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
541 - Support for conditional _LISP.
543 - Support for conditional -hook and -local rules (PR/428).
545 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
547 - Automake will not write any Makefile.ins after the first error it
548 encounters. The previous Makefile.ins (if any) will be left in
549 place. (Warnings will not prevent output, but remember they can
550 be turned into errors with -Werror.)
552 - The restriction that SUBDIRS must contain direct children is gone.
555 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
556 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
560 * Long standing bugs:
562 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
563 so that `make distclean' and `make maintainer-clean' can work.
565 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
567 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
569 - Polish diagnostic when no input file is found.
573 * Long standing bugs:
575 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
576 overridden by the user.
578 - Honor PATH_SEPARATOR in various places of the Automake package, for
581 - Adjust dependency tracking mode detection to ICC 8.0's new output.
584 - Fix install-sh so it can install the `mv' binary... using `mv'.
586 - Fix tru64 dependency tracking for libtool objects.
588 - Work around Exuberant Ctags when creating a TAGS files in a directory
589 without files to scan but with subdirectories to include.
591 * Bugs introduced by 1.8:
593 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
594 not defined in the same conditions as the _LDADD that uses it.
596 - Do not warn when JAVAROOT is overridden, this is legitimate.
600 * Long standing bugs:
602 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
603 or any of the other *dir variables contain a space.
605 Please note that Automake does not and cannot support spaces in
606 filenames that are involved during the build. This change affects
607 only installation paths, so that `make install' does not bomb out
608 in packages configured with
609 ./configure --prefix '/c/Program Files'
611 - Fix the depfiles output so it works with GNU sed (<4.1) even when
612 POSIXLY_CORRECT is set.
614 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
615 since Autoconf 2.54, which defines LIBOBJS itself.
617 - Fix a potential (but unlikely) race condition in parallel elisp
618 builds. (Introduced in 1.7.3.)
620 - Do not assume that users override _DEPENDENCIES in all conditions
621 where Automake will try to define them.
623 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
624 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
627 This fix also affects the $(mkdir_p) variable defined since
628 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
629 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
631 - Secure temporary directory creation in `make distcheck'. (PR/413)
633 - Do not generate two build rules for `parser.h' when the
634 parser appears in two different conditionals.
636 - Work around a Solaris 8 /bin/sh bug in the test for dependency
637 checking. Usually ./configure will not pick this shell; so this
638 fix only helps cases where the shell is forced to /bin/sh.
640 * Bugs introduced by 1.8:
642 - In some situations (hand-written `m4_include's), aclocal would
643 call the `File::Spec->rel2abs' method, which was only introduced
644 in Perl 5.6. This new version reestablish support Perl 5.005.
646 It is likely that the next major Automake releases will require at
647 least Perl 5.6. Consider upgrading your development environment
648 if you are still using the five-year-old Perl 5.005.
650 - Automake would sometimes fail to define rules for targets listed
651 in variables defined in multiple conditions. For instance on
657 it would define only the `a.$(OBJEXT): a.c' rule and omit the
658 `b.$(OBJEXT): b.c' rule.
660 * New sections in manual:
662 - Third-Party Makefiles: how to interface third party Makefiles.
663 - Upgrading: upgrading packages to newer Automake versions.
664 - Multiple Outputs: handling tools that produce many outputs.
668 * A (well known) portability bug slipped in the changes made to
669 install-sh in Automake 1.8.1. The broken install-sh would refuse to
670 install anything on Tru64.
672 * Fix install rules for conditionally built python files. (This never
677 * Bugs introduced by 1.8:
679 - Fix Config.pm import error with old Perl versions (at least
680 5.005_03). One symptom is that aclocal could not find its macro
683 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
684 created by `make install' are always world readable, even if the
685 installer happens to have an overly restrictive umask (e.g. 077).
686 This was a mistake and has been reverted. There are at least two
687 reasons why we must not use `-m 0755':
688 - it causes special bits like SGID to be ignored,
689 - it may be too restrictive (some setups expect 775 directories).
691 - Fix aclocal to honor definitions located in files which have been
692 m4_included manually. aclocal 1.8 had been updated to check
693 m4_included files for new requirements, but forgot that these
694 m4_included files can also provide new definitions.
696 Note that if you have such a setup, we recommend you get rid of
697 it. In the past, there was a reason to m4_include files manually:
698 aclocal used to duplicate entire M4 files into aclocal.m4, even
699 files that were distributed. Some packages were therefore
700 m4_including the distributed file directly, and playing some
701 tricks to ensure aclocal would not copy that file to aclocal.m4,
702 in order to limit the amount of duplication. Since aclocal 1.8.x
703 will precisely output m4_includes for local M4 files, we recommend
704 that you clean up your setup, removing all manual m4_includes and
705 letting aclocal output them.
707 - Output detailed menus in the Info version if the Automake manual,
708 so that Emacs can locate the indexes.
710 - configure.ac and configure were listed twice in DIST_COMMON (an
711 internal variable where Automake lists configury files to
712 distribute). This was harmless, but unaesthetic.
714 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
715 This was an issue only in the Automake package itself, not in
718 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
719 DEST:SRC. This was wrong, as some packages do
720 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
723 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
724 argument. This caused two kinds of failures:
725 - Rules installing data in a conditionally defined directory
726 failed when that directory was undefined. In this case no
727 argument was supplied.
728 - `make installdirs' failed, because several directories were
729 passed to $(mkdir_p). This was an issue only on platform
730 were $(mkdir_p) is implemented with `install-sh -d'.
731 $(mkdir_p) as been changed to accept 0 or more arguments, as
734 * Long-standing bugs:
736 - Fix an unexpected diagnostic occurring when users attempt
737 to override some internal variables that Automake appends to.
739 - aclocal now scans configure.ac for macro definitions (PR/319).
741 - Fix a portability issue with OSF1/Tru64 Make. If a directory
742 distributes files which are outside itself (this usually occurs
743 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
744 from a parent package), then `make distcheck' fails due to an
745 optimization performed by OSF1/Tru64 Make in its VPATH handling.
746 (tests/subpkg2.test failure)
748 - Fix another portability issue with Sun and OSF1/Tru64 Make.
749 In a VPATH-build configuration, `make install' would install
750 nobase_ files to wrong locations.
752 - Fix a Perl `uninitialized value' diagnostic occurring when
753 automake complains that a Texinfo file does not have a
754 @setfilename statement.
756 - Erase config.status.lineno during `make distclean'. This file
757 can be created by config.status. Automake already knew about
758 configure.lineno, but forgot config.status.lineno.
760 - Distribute all files, even those which are built and installed
761 conditionally. This change affects files listed in conditionally
762 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
763 as well as those listed in conditionally defined dist_*_DATA,
764 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
766 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
767 doesn't conform to POSIX.
769 - Normalize help strings for configure variables and options added
774 - Check for python2.4 in AM_PATH_PYTHON.
776 * Spurious failures in test suite:
778 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
779 tests/ltconv.test: fix failures with CVS Libtool.
780 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
781 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
782 fix failures with old Texinfo versions.
788 - The NEWS file is more verbose.
792 - Autoconf 2.58 or greater is required.
796 - Default source file names in the absence of a _SOURCES declaration
797 are made by removing any target extension before appending `.c', so
798 to make the libtool module `foo.la' from `foo.c', you only need to
801 lib_LTLIBRARIES = foo.la
802 foo_la_LDFLAGS = -module
804 For backward compatibility, foo_la.c will be used instead of
805 foo.c if this file exists or is the explicit target of a rule.
806 However -Wobsolete will warn about this deprecated naming.
808 - AR's `cru' flags are now set in a global ARFLAGS variable instead
809 of being hard-coded in each $(AR) invocation, so they can be
810 substituted from configure.ac. This has been requested by people
811 dealing with non-POSIX ar implementations.
813 - New warning option: -Woverride. This will warn about any user
814 target or variable definitions which override Automake
817 - Texinfo rules back up and restore info files when makeinfo fails.
819 - Texinfo rules now support the `html' target.
820 Running this requires Texinfo 4.0 or greater.
822 `html' is a new recursive target, so if your package mixes
823 hand-crafted `Makefile.in's with Automake-generated
824 `Makefile.in's, you should adjust the former to support (or
825 ignore) this target so that `make html' recurses successfully. If
826 you had a custom `html' rule in your `Makefile.am', it's better to
827 rename it as `html-local', otherwise your rule will override
828 Automake's new rule (you can check that by running `automake
829 -Woverride') and that will stop the recursion to subdirectories.
831 Last but not least, this `html' rule is declared PHONY, even when
832 overridden. Fortunately, it appears that few packages use a
833 non-PHONY `html' rule.
835 - Any file which is m4_included from configure.ac will appear as a
836 configure and Makefile.in dependency, and will be automatically
839 - The rules for rebuilding Makefiles and Makefile.ins will now
840 rebuild all Makefiles and all Makefile.ins at once when one of
841 configure's dependencies has changed. This is considerably faster
842 than previous implementations, where config.status and automake
843 were run separately in each directory (this still happens when you
844 change a Makefile.am locally, without touching configure.ac or
845 friends). Doing this also solves a longstanding issue: these
846 rebuild rules failed to work when adding new directories to the
847 tree, forcing you to run automake manually.
849 - For similar reasons, the rules to rebuild configure,
850 config.status, and aclocal.m4 are now defined in all directories.
851 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
852 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
853 should better define them in all directories. This is easily done
854 using an AC_SUBST (make sure you prefix these dependencies with
855 $(top_srcdir) since this variable will appear at different
856 levels of the build tree).
858 - aclocal will now use `m4_include' instead of copying local m4
859 files into aclocal.m4. (Local m4 files are those you ship with
860 your project, other files will be copied as usual.)
862 Because m4_included files are automatically distributed, it means
863 for most projects there is no point in EXTRA_DISTing the list of
864 m4 files which are used. (You can probably get rid of
865 m4/Makefile.am if you had one.)
867 - aclocal will avoid touching aclocal.m4 when possible, so that
868 Autom4te's cache isn't needlessly invalidated. This behavior can
869 be switched off with the new `--force' option.
871 - aclocal now uses Autoconf's --trace to detect macros which are
872 actually used and will no longer include unused macros simply
873 because they where mentioned. This was often the case for macros
874 called conditionally.
876 - New options no-dist and no-dist-gzip.
878 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
879 py-compile, and ylwrap, now all understand --version and --help.
881 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
882 links as part of the distclean target and including source files in
885 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
886 argument. The latter can be used to override the default behavior
889 - Automake will exit with $? = 63 on version mismatch. (So does
890 Autoconf 2.58) missing knows this, and in this case it will
891 emulate the tools as if they were absent. Because older versions
892 of Automake and Autoconf did not use this exit code, this change
893 will only be useful in projects generated with future versions of
896 - When using AC_CONFIG_FILES with multiple input files, Automake
897 generates the first ".in" input file for which a ".am" exists.
898 (Former versions would try to use only the first input file.)
900 - lisp_DATA is now allowed. If you are using the empty ELCFILES
901 idiom to disable byte-compilation of lisp_LISP files, it is
902 recommended that you switch to using lisp_DATA. Note that
903 this is not strictly equivalent: lisp_DATA will install elisp
904 files even if emacs is not installed, while *_LISP do not
905 install anything unless emacs is found.
907 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
908 available. This selection is achieved through the Makefile
909 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
910 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
911 `$(install_sh) -m 0755 -d'.
915 - Because `mkdir -p' is available on most platforms, and we can use
916 `install-sh -d' when it is not, the use of the mkinstalldirs
917 script is being phased out. `automake --add-missing' no longer
918 installs it, and if you remove mkinstalldirs from your package,
919 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
921 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
922 gettextize and autopoint will install it when needed. Automake
923 will continue to define the $(mkinstalldirs) and to distribute
924 mkinstalldirs when this script is in the source tree.
926 - AM_PROG_CC_STDC is now empty. The content of this macro was
927 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
928 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
929 renaming should be safe, even if you have to support several,
930 versions of Automake, because AC_PROG_CC defines this variable
931 since Autoconf 2.54.)
933 - Some users where using the undocumented ACLOCAL_M4_SOURCES
934 variable to override the aclocal.m4 dependencies computed
935 (inaccurately) by older versions of Automake. Because Automake
936 now tracks configure's m4 dependencies accurately (see m4_include
937 above), the use of ACLOCAL_M4_SOURCES should be considered
938 obsolete and will be flagged as such when running `automake
943 - Defining programs conditionally using Automake conditionals no
944 longer leads to a combinatorial explosion. The following
945 construct used to be troublesome when used with dozens of
960 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
962 - Due to implementation constraints, previous versions of Automake
963 proscribed multiple conditional definitions of some variables
973 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
974 This restriction has been lifted, and these variables now
975 support multiple conditional definitions as do other variables.
977 - Cleanup the definitions of $(distdir) and $(top_distdir).
978 $(top_distdir) now points to the root of the distribution
979 directory created during `make dist', as it did in Automake 1.4,
980 not to the root of the build tree as it did in intervening
981 versions. Furthermore these two variables are now only defined in
982 the top level Makefile, and passed to sub-directories when running
985 - The --no-force option now correctly checks the Makefile.in's
986 dependencies before deciding not to update it.
988 - Do not assume that make files are called Makefile in cleaning rules.
990 - Update .info files in the source tree, not in the build tree. This
991 is what the GNU Coding Standard recommend. Only Automake 1.7.x
992 used to update these files in the build tree (previous versions did
993 it in the source tree too), and it caused several problems, varying
994 from mere annoyance to portability issues.
996 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
997 when --add-missing and --force-missing are used. For backward
998 compatibility --add-missing will continue to install COPYING (in
999 `gnu' strictness) when none of these three files exist, but this
1000 use is deprecated: you should better choose a license yourself and
1001 install it once for all in your source tree (and in your code
1004 - Fix ylwrap so that it does not overwrite header files that haven't
1005 changed, as the inline rule already does.
1007 - User-defined rules override automake-defined rules for the same
1008 targets, even when rules do not have commands. This is not new
1009 (and was documented), however some of the automake-generated
1010 rules have escaped this principle in former Automake versions.
1011 Rules for the following targets are affected by this fix:
1013 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1014 info, info-am, install-data-am, install-exec-am, install-info,
1015 install-info-am, install-man, installcheck-am, maintainer-clean,
1016 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1017 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1019 Practically it means that an attempt to supplement the dependencies
1020 of some target, as in
1022 clean: my-clean-rule
1024 will now *silently override* the automake definition of the
1025 rule for this target. Running `automake -Woverride' will diagnose
1026 all such overriding definitions.
1028 It should be noted that almost all these targets support a *-local
1029 variant that is meant to supplement the automake-defined rule
1030 (See node `Extending' in the manual). The above rule should
1033 clean-local: my-clean-rule
1035 These *-local targets have been documented since at least
1036 Automake 1.2, so you should not fear the change if you have
1037 to support multiple automake versions.
1041 - The Automake manual is now distributed under the terms of the GNU FDL.
1043 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1045 - core dumps are no longer removed by the cleaning rules. There are
1046 at least three reasons for this:
1047 1. These files should not be created by any build step,
1048 so their removal do not fit any of the cleaning rules.
1049 Actually, they may be precious to the developer.
1050 2. If such file is created during a build, then it's clearly a
1051 bug Automake should not hide. Not removing the file will
1052 cause `make distcheck' to complain about its presence.
1053 3. Operating systems have different naming conventions for
1054 core dump files. A core file on one system might be a
1055 completely legitimate data file on another system.
1057 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1058 defined by Automake. This means that any definition in the
1059 environment will be used, unless overridden in the Makefile.am or
1060 on the command line. The old behavior, where these variables were
1061 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1062 AC_ARG_VARing each variable from configure.ac.
1064 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1065 documented. (The is not a new feature, these variables have
1066 been there since at least Automake 1.4.)
1068 Bugs fixed in 1.7.9:
1069 * Fix install-strip to work with nobase_ binaries.
1070 * Fix renaming of #line directives in ylwrap.
1071 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1073 Bugs fixed in 1.7.8:
1074 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1075 * Fix detection of Debian's install-info, broken since version 1.5.
1076 (Debian bug #213524).
1077 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1078 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1080 Bugs fixed in 1.7.7:
1081 * The implementation of automake's --no-force option is unreliable,
1082 so this option is ignored in this version. A real fix will appear in
1083 Automake 1.8. (Debian Bug #206299)
1084 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1085 argument is given. (PR/399)
1086 * Do not warn about leading `_' in variable names, even with -Wportability.
1087 * Support user redefinitions of TEXINFO_TEX.
1088 * depcomp: support AIX Compiler version 6.
1089 * Fix missing rebuilds during `make dist' with BSD make.
1090 (Could produce tarballs containing out-of-date files.)
1091 * Resurrect multilib support.
1092 * Noteworthy manual updates:
1093 - Extending aclocal: how to write m4 macros that won't trigger warnings
1095 - A Shared Library: Rewrite and split into subsections.
1097 Bugs fixed in 1.7.6:
1098 * Fix depcomp's icc mode for ICC 7.1.
1099 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1100 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1101 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1102 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1103 * Remove Latin-1 characters from elisp-comp.
1104 * Update the manual's @dircategory to match the Free Software Directory.
1106 Bugs fixed in 1.7.5:
1107 * Update install-sh's license to remove an advertising clause.
1108 (Debian bug #191717)
1109 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1110 that caused invalid Makefile.ins to be generated.
1111 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1112 * New FAQ entry: renamed objects.
1114 Bugs fixed in 1.7.4:
1115 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1116 the Emacs implementation)
1117 * Fix output of aclocal.m4 dependencies in subdirectories.
1118 * Use `mv -f' instead of `mv' in fastdep rules.
1119 * Upgrade mdate-sh to work on OS/2.
1120 * Don't byte-compile elisp files when ELCFILES is set empty.
1121 (this documented feature was broken by 1.7.3)
1122 * Diagnose trailing backslashes on last line of Makefile.am.
1123 * Diagnose whitespace following trailing backslashes.
1124 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
1125 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
1127 * `make install' will build `BUILT_SOURCES' first.
1128 * Minor documentation fixes.
1130 Bugs fixed in 1.7.3:
1131 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1132 * Query distutils for `pythondir' and `pythonexecdir', instead of
1133 using an hardcoded path. This should allow builds on 64-bit
1134 distributions that usually use lib64/ instead of lib/.
1135 * AM_PATH_PYTHON will also search for python2.3.
1136 * elisp files are now built all at once instead of one by one. Besides
1137 incurring a speed-up, this is required to support interdependent elisp files.
1138 * Support for DJGPP:
1139 - `make distcheck' will now work in `_inst/' and `_build' instead
1140 of `=inst/' and `=build/'
1141 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1142 - install/uninstall `*.i[0-9][0-9]'-style info files
1143 - more changes that affect only the Automake package (not its output)
1144 * Fix some incompatibilities with upcoming perl-5.10.
1145 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1146 PACKAGE and VERSION.
1148 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1149 is troublesome with gcc and Solaris compilers. (PR/385)
1150 - makedepend mode: work with Libtool. (PR/385 too)
1152 * better support for unusual gettext setups, such as multiple po/ directories
1154 - Flag missing po/ and intl/ directories as warnings, not errors.
1155 - Disable these warnings if po/ does not exist.
1156 * Noteworthy manual updates:
1158 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1160 - Document `AM_YFLAGS = -d'. (PR/382)
1162 Bugs fixed in 1.7.2:
1163 * Fix installation and uninstallation of Info files built in subdirectories.
1164 * Do not run `./configure --with-included-gettext' during `make distcheck'
1165 if AM_GNU_GETTEXT([external]) is used.
1166 * Correctly uninstall renamed man pages.
1167 * Do not strip escaped newline in variables defined in one condition
1168 and augmented in another condition.
1169 * Fix ansi2knr rules for LIBOBJS sources.
1170 * Clean all known Texinfo index files, not only those which appear to
1171 be used, because we cannot know wich indexes are used in included files.
1172 (PR/375, Debian Bug #168671)
1173 * Honor only the first @setfilename seen in a Texinfo file.
1174 * Treat "required file X not found" diagnostics as errors (exit status 1).
1175 * Don't complain that a required file is not found when it is a Makefile
1177 * Don't use single suffix inference rules when building `.info'-less
1178 Info files, for the sake of Solaris make.
1179 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1180 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1181 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1182 * Fix building of deansified files from subdirectories. (PR/370)
1183 * Add missing `fi' in the .c->.obj rules.
1184 * Improve install-sh to work even when names contain spaces or certain
1185 (but not all) shell metachars.
1186 * Fix the following spurious failures in the test suite:
1187 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1188 * Noteworthy manual updates:
1189 - Augment the section about BUILT_SOURCES.
1190 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1192 Bugs fixed in 1.7.1:
1193 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1195 * Aclocal should now recognize macro names containing parentheses, e.g.
1196 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1197 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1199 * Install Python files even if they were built. (PR/369)
1200 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1201 version might not be defined in the latter. (PR/358)
1202 * Reorder arguments passed to a couple of commands, so things works
1203 when POSIXLY_CORRECT=1.
1204 * Fix a regex that can cause Perl to segfault on large input.
1206 * Fix distribution of packages that have some sources defined conditionally,
1207 as in the `Conditional compilation using Automake conditionals' example
1209 * Fix spurious test suite failures on IRIX.
1210 * Don't report a required variable as undefined if it has been
1211 defined conditionally for the "right" conditions.
1212 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1213 `make distcheck' fails.
1214 * Fix distribution of included Makefile fragment, so we don't create
1215 spurious directories in the distribution. (PR/366)
1216 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1219 * Autoconf 2.54 is required.
1220 * `aclocal' and `automake' will no longer warn about obsolete
1221 configure macros. This is done by `autoconf -Wobsolete'.
1222 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1223 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1224 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1225 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1226 `configure.ac' for you.
1227 * Support for per-program and per-library `_CPPFLAGS'.
1228 * New `ctags' target (builds CTAGS files).
1229 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category

1231 * Honor the WARNINGS environment variable.
1232 * Omit the call to depcomp when using gcc3: call the compiler directly.
1233 * A new option, std-options, tests that programs support --help and --version

1241 * `+=' can be used in conditionals, even if the augmented variable
1242 was defined for another condition.
1243 * Makefile fragments (inserted with `include') are always distributed.
1244 * Use Autoconf's --trace interface to inspect configure.ac and get
1245 a more accurate view of it.
1246 * Add support for extending aclocal's default macro search path
1247 using a `dirlist' file within the aclocal directory.
1248 * automake --output-dir is deprecated.
1249 * The part of the distcheck target that checks whether uninstall actually
1250 removes all installed files has been moved in a separate target,
1251 distuninstallcheck, so it can be overridden easily.
1255 * Support for AM_INIT_GETTEXT([external])
1256 * Bug fixes, including:
1257 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1258 - nobase_ programs and scripts honor --program-transform correctly.
1259 - Erase configure.lineno during `make distclean'.
1260 - Erase YACC and LEX outputs during `make maintainer-clean'.
1263 * Many bug fixes, including:
1264 - Requiring the current version works.
1265 - Fix "$@" portability issues (for Zsh).
1266 - Fix output of dummy dependency files in presence of post-processed
1268 - Don't compute dependencies in background to avoid races with libtool.
1269 - Fix handling of _OBJECTS variables for targets sharing source variables.
1270 - Check dependency mode for Java when AM_PROG_GCJ is used.

1275 - Don't choke on AM_LDFLAGS definitions.
1276 - Clean libtool objects from subdirectories.
1277 - Allow configure variables with reserved suffix and unknown prefix
1278 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1279 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1282 * Autoconf 2.52 is required.
1283 * automake no longer run libtoolize.
1284 This is the job of autoreconf (from GNU Autoconf).

1286 * `dist-gzip' generates the Gzip tar file only.
1287 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1288 explosion. Makefile.in's keep a reasonable size.
1289 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1290 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1292 * `#line' of Lex and Yacc files are properly set.
1293 * EXTRA_DIST can contain generated directories.
1294 * Support for dot-less extensions in suffix rules.

1306 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1307 (Note that "pkgname" is not "tarname", see the manual for details.)
1308 It is also possible to pass a list of global Automake options as
1309 first argument to this new form of AM_INIT_AUTOMAKE.
1310 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1311 to be a real assembler.
1312 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1313 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1314 * aclocal and automake are also installed with the version number
1315 appended, and some of the install directory names have changed.
