5 - automake now generates silenced rules for texinfo outputs.
7 - The deprecated options `--output-dir', `--Werror' and `--Wno-error'
12 - The `--acdir' option is deprecated. Now you should use th new options
13 `--automake-acdir' and `--system-acdir' instead.
17 - New `cscope' target to build a cscope database for the source tree.
19 * Changes to Automake-generated testsuite harnesses:
21 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
22 and unexpected or internal error, or a failure to set up the test case
23 scenario) have their outcome reported as an 'ERROR' now. Previous
24 versions of automake reported such an outcome as a 'FAIL' (the only
25 difference with normal failures being that hard errors were counted
26 as failures even when the test originating them was listed in
29 - The testsuite summary displayed by the parallel-test harness has a
30 completely new format, that always list the numbers of passed, failed,
31 xfailed, xpassed, skipped and errored tests, even when these numbers
32 are zero (but using smart coloring when the color-tests option is in
35 - The default testsuite driver offered by the 'parallel-tests' option is
36 now implemented (partly at least) with the help of automake-provided
37 auxiliary scripts (e.g., `test-driver'), instead of relying entirely
38 on code in the generated Makefile.in.
39 This has two noteworthy implications. The first one is that projects
40 using the `parallel-tests' option should now either run automake with
41 the `--add-missing' option, or manually copy the `test-driver' script
42 into their tree. The second, and more important, implication is that
43 now, when the `parallel-tests' option is in use, TESTS_ENVIRONMENT can
44 not be used anymore to define a test runner, and the command specified
45 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
46 program or script. For example, this is still a valid usage (albeit
50 if test -n '$(STRICT_TESTS)'; then \
55 LOG_COMPILER = $(SHELL) $$maybe_errexit
57 while this is not anymore:
60 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
65 run_with_perl_or_shell () \
67 if grep -q '^#!.*perl' $$1; then
73 LOG_COMPILER = run_with_per_or_shell
75 - The package authors can now use customary testsuite drivers within
76 the framework provided by the 'parallel-tests' testsuite harness.
77 Consistently with the existing syntax, this can be done by defining
78 special makefile variables `LOG_DRIVER' and `<ext>_LOG_DRIVER'.
80 - A new developer-reserved variable `AM_TESTS_FD_REDIRECT' can be used
81 to redirect/define file descriptors used by the test scripts.
83 - The parallel-tests harness generates now, in addition the `.log' files
84 holding the output produced by the test scripts, a new set of `.trs'
85 files, holding "metadata" derived by the execution of the test scripts;
86 among such metadata are the outcomes of the test cases run by a script.
88 - Initial and still experimental support for the TAP test protocol is
91 * Miscellaneous changes:
93 - The `dist' and `dist-all' targets now can run compressors in parallel.
95 - The `lzma' compression scheme and associated automake option `dist-lzma'
96 is obsoleted by `xz' and `dist-xz' due to upstream changes.
98 - "make dist" can now create lzip-compressed tarballs.
100 - You may adjust the compression options used in dist-xz and dist-bzip2.
101 The default is still -9 for each, but you may specify a different
102 level via the XZ_OPT and BZIP2 envvars respectively. E.g.,
103 "make dist-xz XZ_OPT=-7" or "make dist-xz BZIP2=-5"
105 - Messages of types warning or error from `automake' and `aclocal' are now
106 prefixed with the respective type, and presence of -Werror is noted.
108 - The `compile' script now converts some options for MSVC for a better
109 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
111 - Automake's early configure-time sanity check now tries to avoid sleeping
112 for a second, which slowed down cached configure runs noticeably. In that
113 case, it will check back at the end of the configure script to ensure that
114 at least one second has passed, to avoid time stamp issues with makefile
115 rules rerunning autotools programs.
117 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES and
118 adds them to the normal list of dependencies, but without overwriting the
119 foo_DEPENDENCIES variable, which is normally computed by automake.
121 - C source and header files derived from non-distributed Yacc sources are
122 now removed by "make clean", not only by "make maintainer-clean".
124 - A developer that needs to pass specific flags to configure at "make
125 distcheck" time can now, and indeed he's advised to, do so by defining
126 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
127 instead of the old DISTCHECK_CONFIGURE_FLAGS.
128 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
129 user; still, the old Makefile.am files that used to define it should
130 still continue to work as before.
132 - Support for automatic de-ANSI-fication has been removed.
136 - Lots of minor bugfixes.
138 * Bugs introduced by 1.11:
140 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
141 trailing white space in the test list (`TESTS = foo $(EMPTY)'), and
142 does not report spurious successes when used with concurrent FreeBSD
143 make (e.g., "make check -j3").
145 - The `silent-rules' option now also silences all compile rules if dependency
146 tracking is disabled. Also, when `silent-rules' is not used, the output from
147 `make' does not contain spurious extra lines with only a backslash in them
148 any more; it now again matches that from pre-1.11 Automake.
150 - The `dist-xz' option now uses `xz -9' for maximum compression.
152 - The AM_COND_IF macro also works if the shell expression for the conditional
153 is no longer valid for the condition.
155 * Long standing bugs:
157 - Automake now warns about more primary/directory invalid combinations,
158 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
160 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
161 even if the `--prefix' argument pointed outside of a system directory.
162 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
163 `get_python_lib' function if it points outside the configured prefix,
164 unless the `--prefix' argument was either `/usr' or below `/System'.
166 - The testsuite does not try to change the mode of `ltmain.sh' files from
167 a Libtool installation (symlinked to test directories) any more.
169 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
170 tools are preferred in a cross-compile setup.
172 - The distribution is tarred up with mode 755 now by the `dist*' targets.
173 This fixes a race condition where untrusted users could modify files
174 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
175 build directory was world-searchable. This is CVE-2009-4029.
177 - Several scripts as well as the parallel-tests testsuite driver now
178 exit with the right exit status upon receiving a signal.
180 - A per-Makefile.am setting of -Werror does not carry over to the
181 handling of other Makefile.am files any more.
183 - The order of Yacc and Lex flags is fixed to be consistent with other
184 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
185 $(LFLAGS), so that the user variables override the developer variables.
187 - Rules generated by Automake now try harder to not change any files when
188 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
189 Yacc source files and the rule to update config.h.
191 - The code for automatic dependency tracking works around a Solaris
192 make bug triggered by sources containing repeated slashes when the
193 `subdir-objects' option was used.
195 - Automake now detects the presence of the `-d' flag in the various
196 `*YFLAGS' variables even when their definitions involve indirections
197 through other variables, such as in:
199 AM_YFLAGS = $(foo_opts)
201 - Automake now complains if a `*YFLAGS' variable has any conditional
202 content, not only a conditional definition.
204 - Explicit enabling and/or disabling of Automake warning categories
205 through the `-W...' options now always takes precedence over the
206 implicit warning level implied by Automake strictness (foreign, gnu
207 or gnits), regardless of the order in which such strictness and
208 warning flags appear. For example, a setting like:
209 AUTOMAKE_OPTIONS = -Wall --foreign
210 will cause the warnings in category `portability' to be enabled, even
211 if those warnings are by default disabled in `foreign' strictness.
213 - The parallel-tests driver now does not produce erroneous results
214 with Tru64/OSF 5.1 sh upon unreadable log files any more.
216 - The makedepend and hp depmodes now works better with VPATH builds.
218 - Java sources specified with check_JAVA are not compiled anymore upon
219 "make all", but only upon "make check".
221 - Now aclocal and automake, when they've to spawn autoconf or autom4te
222 processes, honour the configure-time definitions of AUTOCONF and
227 * Version requirements:
229 - Autoconf 2.62 or greater is required.
231 * Changes to aclocal:
233 - The autoconf version check implemented by aclocal in aclocal.m4
234 (and new in Automake 1.10) is degraded to a warning. This helps
235 in the common case where the Autoconf versions used are compatible.
237 * Changes to automake:
239 - The automake program can run multiple threads for creating most
240 Makefile.in files concurrently, if at least Perl 5.7.2 is available
241 with interpreter-based threads enabled. Set the environment variable
242 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
243 enable this experimental feature.
245 * Changes to Libtool support:
247 - Libtool generic flags are now passed to the install and uninstall
250 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
251 config.lt is removed correctly now.
255 - subdir-object mode works now with Fortran (F77, FC, preprocessed
256 Fortran, and Ratfor).
258 - For files with extension .f90, .f95, .f03, or .f08, the flag
259 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
261 - Files with extension .sx are also treated as preprocessed assembler.
263 - The default source file extension (.c) can be overridden with
264 AM_DEFAULT_SOURCE_EXT now.
266 - Python 3.0 is supported now, Python releases prior to 2.0 are no
269 - AM_PATH_PYTHON honors python's idea about the site directory.
271 - There is initial support for the Vala programming language, when using
274 * Miscellaneous changes:
276 - Automake development is done in a git repository on Savannah now, see
278 http://git.sv.gnu.org/gitweb/?p=automake.git
280 A read-only CVS mirror is provided at
282 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
283 checkout -d automake HEAD
285 - "make dist" can now create xz-compressed tarballs,
286 as well as (deprecated?) lzma-compressed tarballs.
288 - `automake --add-missing' will by default install the GPLv3 file as
289 COPYING if it is missing. It will also warn that the license file
290 should be added to source control. Note that Automake will never
291 overwrite an existing COPYING file, even when the `--force-missing'
294 - The manual is now distributed under the terms of the GNU FDL 1.3.
296 - Automake ships and installs man pages for automake and aclocal now.
298 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
300 - install-sh supports -C, which does not update the installed file
301 (and its time stamps) if the contents did not change.
303 - The `gnupload' script has been revamped.
305 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
307 - The targets `install' and `uninstall' are more efficient now, in that
308 for example multiple files from one Automake variable such as
309 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
310 invocation if they do not have to be renamed.
312 Both install and uninstall may sometimes enter (`cd' into) the target
313 installation directory now, when no build-local scripts are used.
315 Both install and uninstall do not fail anymore but do nothing if an
316 installation directory variable like `bindir' is set to the empty string.
318 For built-in rules, `make install' now fails reliably if installation
319 of a file failed. Conversely, `make uninstall' even succeeds when
320 issued multiple times.
322 These changes may need some adjustments from users: For example,
323 some `install' programs refuse to install multiple copies of the
324 same file in one invocation, so you may need to remove duplicate
325 entries from file lists.
327 Also, within one set of files, say, nobase_data_DATA, the order of
328 installation may be changed, or even unstable among different hosts,
329 due to the use of associative arrays in awk. The increased use of
330 awk matches a similar move in Autoconf to provide for better scaling.
332 Further, most undocumented per-rule install command variables such as
333 binSCRIPT_INSTALL have been removed because they are not needed any
334 more. Packages which use them should be using the appropriate one of
335 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
336 counterpart, depending on the type of files and the need for automatic
337 target directory creation.
339 - The "deleted header file problem" for *.m4 files is avoided by
340 stub rules. This allows `make' to trigger a rerun of `aclocal'
341 also if some previously needed macro file has been removed.
343 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
344 an otherwise up to date tree.
346 - The `color-tests' option causes colored test result output on terminals.
348 - The `parallel-tests' option enables a new test driver that allows for
349 parallel test execution, inter-test dependencies, lazy test execution
350 for unit-testing, re-testing only failed tests, and formatted result output
351 as RST (reStructuredText) and HTML. Enabling this option may require some
352 changes to your test suite setup; see the manual for details.
354 - The `silent-rules' option enables Linux kernel-style silent build output.
355 This option requires the widely supported but non-POSIX `make' feature
356 of recursive variable expansion, so do not use it if your package needs
357 to build with `make' implementations that do not support it.
359 To enable less verbose build output, the developer has to use the Automake
360 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
361 macro. The user may then set the default verbosity by passing the
362 `--enable-silent-rules' option to `configure'. At `make' run time, this
363 default may be overridden using `make V=0' for less verbose, and `make V=1'
364 for backward-compatible verbose output.
366 - New prefix `notrans_' for manpages which should not be transformed
367 by --program-transform.
369 - New macro AM_COND_IF for conditional evaluation and conditional
372 - For AC_CONFIG_LINKS, if source and destination are equal, do not
373 remove the file in a non-VPATH build. Such setups work with Autoconf
376 - AM_MAINTAINER_MODE now allows for an optional argument specifying
379 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
380 useful especially for multi-line values.
382 - Automake's early configure-time sanity check now diagnoses an
383 unsafe absolute source directory name and makes configure fail.
385 - The Automake macros and rules cope better with whitespace in the
386 current directory name, as long as the relative path to `configure'
387 does not contain whitespace. To this end, the values of `$(MISSING)'
388 and `$(install_sh)' may contain suitable quoting, and their expansion
389 might need `eval'uation if used outside of a makefile. These
390 undocumented variables may be used in several documented macros such
391 as $(AUTOCONF) or $(MAKEINFO).
395 * Long standing bugs:
397 - Fix aix dependency tracking for libtool objects.
399 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
400 unnecessary use of the `compile' script.
402 - For nobase_*_LTLIBRARIES with nonempty directory components, the
403 correct `-rpath' argument is used now.
405 - `config.status --file=Makefile depfiles' now also works with the
406 extra quoting used internally by Autoconf 2.62 and newer
407 (it used to work only without the `--file=' bit).
409 - The `missing' script works better with versioned tool names.
411 - Semantics for `missing help2man' have been revamped:
413 Previously, if `help2man' was not present, `missing help2man' would have
414 the following semantics: if some man page was out of date but present, then
415 a warning would be printed, but the exit status was 0. If the man page was
416 not present at all, then `missing' would create a replacement man page
417 containing an error message, and exit with a status of 2. This does not play
418 well with `make': the next run will see this particular man page as being up
419 to date, and will only error out on the next generated man page, if any;
420 repeat until all pages are done. This was not desirable.
422 These are the new semantics: if some man page is not present, and help2man
423 is not either, then `missing' will warn and generate the replacement page
424 containing the error message, but exit successfully. However, `make dist'
425 will ensure that no such bogus man pages are packaged into a tarball.
427 - Targets provided by automake behave better with `make -n', in that they
428 take care not to create files.
430 - `config.status Makefile... depfiles' works fine again in the presence of
431 disabled dependency tracking.
433 - The default no-op recursive rules for these targets also work with BSD make
434 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
436 - `make distcheck' works also when both a directory and some file below it
437 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
439 - Texinfo dvi, ps, pdf, and html output files are not removed upon
440 `make mostlyclean' any more; only the LaTeX by-products are.
442 - Renamed objects also work with the `subdir-objects' option and
443 source file languages which Automake does not know itself.
445 - `automake' now correctly complains about variable assignments which are
446 preceded by a comment, extend over multiple lines with backslash-escaped
447 newlines, and end in a comment sign. Previous versions would silently
448 and wrongly ignore such assignments completely.
450 * Bugs introduced by 1.10:
452 - Fix output of dummy dependency files in presence of post-processed
453 Makefile.in's again, but also cope with long lines.
455 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
456 that have been declared as programs in the same Makefile.
457 This is for consistency with the analogous change to TESTS in 1.10.
459 - Fix order of standard includes to again be `-I. -I$(srcdir)',
460 followed by directories containing config headers.
464 * Version requirements:
466 - Autoconf 2.60 or greater is required.
468 - Perl 5.6 or greater is required.
470 * Changes to aclocal:
472 - aclocal now also supports -Wmumble and -Wno-mumble options.
474 - `dirlist' entries (for the aclocal search path) may use shell
475 wildcards such as `*', `?', or `[...]'.
477 - aclocal supports an --install option that will cause system-wide
478 third-party macros to be installed in the local directory
479 specified with the first -I flag. This option also uses #serial
480 lines in M4 files to upgrade local macros.
482 The new aclocal options --dry-run and --diff help to review changes
483 before they are installed.
485 - aclocal now outputs an autoconf version check in aclocal.m4 in
486 projects using automake.
488 For a few years, automake and aclocal have been calling autoconf
489 (or its underlying engine autom4te) to accurately retrieve the
490 data they need from configure.ac and its siblings. Doing so can
491 only work if all autotools use the same version of autoconf. For
492 instance a Makefile.in generated by automake for one version of
493 autoconf may stop working if configure is regenerated with another
494 version of autoconf, and vice versa.
496 This new version check ensures that the whole build system has
497 been generated using the same autoconf version.
499 * Support for new Autoconf macros:
501 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
503 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
504 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
505 in different directories. However, only one instance of such a
506 library objects directory is supported.
508 * Change to Libtool support:
510 - Libtool generic flags (those that go before the --mode=MODE option)
511 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
513 * Yacc and Lex changes:
515 - The rebuild rules for distributed Yacc and Lex output will avoid
516 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
519 - ylwrap is now always used for lex and yacc source files,
520 regardless of whether there is more than one source per directory.
524 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
525 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
526 tracking, unlike non-preprocessed assembler (*.s).
528 - subdir-object mode works now with Assembler. Automake assumes
529 that the compiler understands `-c -o'.
531 - Preprocessed assembler (*.S) compilation now also honors
532 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
534 - Improved support for Objective C:
535 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
536 - A new section of the manual documents the support.
538 - New support for Unified Parallel C:
539 - AM_PROG_UPC looks for a UPC compiler.
540 - A new section of the manual documents the support.
542 - Per-target flags are now correctly handled in link rules.
544 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
545 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
546 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
547 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
549 The fix for compiler flags (i.e., using maude_CFLAGS instead of
550 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
551 is expected to work (and actually works during compilation).
553 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
554 "in addition to" breaks backward compatibility with older versions.
555 If your package used both variables, as in
557 AM_LDFLAGS = common flags
559 a_LDFLAGS = more flags
562 and assumed *_LDFLAGS would sum up, you should rewrite it as
564 AM_LDFLAGS = common flags
566 a_LDFLAGS = $(AM_LDFLAGS) more flags
569 This new behavior of *_LDFLAGS is more coherent with other
570 per-target variables, and the way *_LDFLAGS variables were
571 considered internally.
573 * New installation targets:
575 - New targets mandated by GNU Coding Standards:
580 By default they will only install Texinfo manuals.
581 You can customize them with *-local variants:
587 - The undocumented recursive target `uninstall-info' no longer exists.
588 (`uninstall' is in charge of removing all possible documentation
589 flavors, including optional formats such as dvi, ps, or info even
590 when `no-installinfo' is used.)
592 * Miscellaneous changes:
594 - Automake no longer complains if input files for AC_CONFIG_FILES
595 are specified using shell variables.
597 - clean, distribution, or rebuild rules are normally disabled for
598 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
599 AC_CONFIG_LINK specified using shell variables. However, if these
600 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
601 be able to output rules anyway.
602 (See the Automake documentation for AC_CONFIG_FILES.)
604 - $(EXEEXT) is automatically appended to filenames of TESTS
605 that have been declared as programs in the same Makefile.
606 This is mostly useful when some check_PROGRAMS are listed in TESTS.
608 - `-Wportability' has finally been turned on by default for `gnu' and
609 `gnits' strictness. This means, automake will complain about %-rules
610 or $(GNU Make functions) unless you switch to `foreign' strictness or
611 use `-Wno-portability'.
613 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
614 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
615 $(mkdir_p) variable is still defined (to the same value as
616 $(MKDIR_P)) but should be considered obsolete. If you are using
617 $(mkdir_p) in some of your rules, please plan to update them to
618 $(MKDIR_P) at some point.
620 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
621 They still work in this release, but may be withdrawn in a future one.
623 - Inline compilation rules for gcc3-style dependency tracking are
626 - Automake installs a "Hello World!" example package in $(docdir).
627 This example is used throughout the new "Autotools Introduction"
628 chapter of the manual.
632 * Makefile.in bloat reduction:
634 - Inference rules are used to compile sources in subdirectories when
635 the `subdir-objects' option is used and no per-target flags are
636 used. This should reduce the size of some projects a lot, because
637 Automake used to output an explicit rule for each such object in
640 - Automake no longer outputs three rules (.o, .obj, .lo) for each
641 object that must be built with explicit rules. It just outputs
642 the rules required to build the kind of object considered: either
643 the two .o and .obj rules for usual objects, or the .lo rule for
646 * Change to Libtool support:
648 - Libtool tags are used with libtool versions that support them.
649 (I.e., with Libtool 1.5 or greater.)
651 - Automake is now able to handle setups where a libtool library is
652 conditionally installed in different directories, as in
655 lib_LTLIBRARIES = liba.la
657 pkglib_LTLIBRARIES = liba.la
659 liba_la_SOURCES = ...
661 * Changes to aclocal:
663 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
664 really evaluated, before it decides to include them in aclocal.m4.
665 This solves nasty problems with conditional redefinitions of
666 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
667 *.m4 files to be included in any project using these macros.
668 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
669 most famous instance of this bug.)
671 - Do not complain about missing conditionally AC_REQUIREd macros
672 that are not actually used. In 1.8.x aclocal would correctly
673 determine which of these macros were really needed (and include
674 only these in the package); unfortunately it would also require
675 all of them to be present in order to run. This created
676 situations were aclocal would not work on a tarball distributing
677 all the macros it uses. For instance running aclocal on a project
678 containing only the subset of the Gettext macros in use by the
679 project did not work, because gettext conditionally requires other
682 * Portability improvements:
684 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
685 tar-pax. The new option filename-length-max=99 helps diagnosing
686 filenames that are too long for tar-v7. (PR/414)
688 - Variables aumented with `+=' are now automatically flattened (i.e.,
689 trailing backslashes removed) and then wrapped around 80 colummns
690 (adding trailing backslashes). In previous versions, a long series
696 would result in a single-line definition of VAR that could possibly
697 exceed the maximum line length of some make implementations.
699 Non-augmented variables are still output as they are defined in
704 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
705 Works the same as the old Fortran 77 implementation; just replace
706 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
707 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
709 - Support for conditional _LISP.
711 - Support for conditional -hook and -local rules (PR/428).
713 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
715 - Automake will not write any Makefile.ins after the first error it
716 encounters. The previous Makefile.ins (if any) will be left in
717 place. (Warnings will not prevent output, but remember they can
718 be turned into errors with -Werror.)
720 - The restriction that SUBDIRS must contain direct children is gone.
723 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
724 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
728 * Long standing bugs:
730 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
731 so that `make distclean' and `make maintainer-clean' can work.
733 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
735 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
737 - Polish diagnostic when no input file is found.
741 * Long standing bugs:
743 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
744 overridden by the user.
746 - Honor PATH_SEPARATOR in various places of the Automake package, for
749 - Adjust dependency tracking mode detection to ICC 8.0's new output.
752 - Fix install-sh so it can install the `mv' binary... using `mv'.
754 - Fix tru64 dependency tracking for libtool objects.
756 - Work around Exuberant Ctags when creating a TAGS files in a directory
757 without files to scan but with subdirectories to include.
759 * Bugs introduced by 1.8:
761 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
762 not defined in the same conditions as the _LDADD that uses it.
764 - Do not warn when JAVAROOT is overridden, this is legitimate.
768 * Long standing bugs:
770 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
771 or any of the other *dir variables contain a space.
773 Please note that Automake does not and cannot support spaces in
774 filenames that are involved during the build. This change affects
775 only installation paths, so that `make install' does not bomb out
776 in packages configured with
777 ./configure --prefix '/c/Program Files'
779 - Fix the depfiles output so it works with GNU sed (<4.1) even when
780 POSIXLY_CORRECT is set.
782 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
783 since Autoconf 2.54, which defines LIBOBJS itself.
785 - Fix a potential (but unlikely) race condition in parallel elisp
786 builds. (Introduced in 1.7.3.)
788 - Do not assume that users override _DEPENDENCIES in all conditions
789 where Automake will try to define them.
791 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
792 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
795 This fix also affects the $(mkdir_p) variable defined since
796 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
797 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
799 - Secure temporary directory creation in `make distcheck'. (PR/413)
801 - Do not generate two build rules for `parser.h' when the
802 parser appears in two different conditionals.
804 - Work around a Solaris 8 /bin/sh bug in the test for dependency
805 checking. Usually ./configure will not pick this shell; so this
806 fix only helps cases where the shell is forced to /bin/sh.
808 * Bugs introduced by 1.8:
810 - In some situations (hand-written `m4_include's), aclocal would
811 call the `File::Spec->rel2abs' method, which was only introduced
812 in Perl 5.6. This new version reestablish support Perl 5.005.
814 It is likely that the next major Automake releases will require at
815 least Perl 5.6. Consider upgrading your development environment
816 if you are still using the five-year-old Perl 5.005.
818 - Automake would sometimes fail to define rules for targets listed
819 in variables defined in multiple conditions. For instance on
825 it would define only the `a.$(OBJEXT): a.c' rule and omit the
826 `b.$(OBJEXT): b.c' rule.
828 * New sections in manual:
830 - Third-Party Makefiles: how to interface third party Makefiles.
831 - Upgrading: upgrading packages to newer Automake versions.
832 - Multiple Outputs: handling tools that produce many outputs.
836 * A (well known) portability bug slipped in the changes made to
837 install-sh in Automake 1.8.1. The broken install-sh would refuse to
838 install anything on Tru64.
840 * Fix install rules for conditionally built python files. (This never
845 * Bugs introduced by 1.8:
847 - Fix Config.pm import error with old Perl versions (at least
848 5.005_03). One symptom is that aclocal could not find its macro
851 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
852 created by `make install' are always world readable, even if the
853 installer happens to have an overly restrictive umask (e.g. 077).
854 This was a mistake and has been reverted. There are at least two
855 reasons why we must not use `-m 0755':
856 - it causes special bits like SGID to be ignored,
857 - it may be too restrictive (some setups expect 775 directories).
859 - Fix aclocal to honor definitions located in files which have been
860 m4_included manually. aclocal 1.8 had been updated to check
861 m4_included files for new requirements, but forgot that these
862 m4_included files can also provide new definitions.
864 Note that if you have such a setup, we recommend you get rid of
865 it. In the past, there was a reason to m4_include files manually:
866 aclocal used to duplicate entire M4 files into aclocal.m4, even
867 files that were distributed. Some packages were therefore
868 m4_including the distributed file directly, and playing some
869 tricks to ensure aclocal would not copy that file to aclocal.m4,
870 in order to limit the amount of duplication. Since aclocal 1.8.x
871 will precisely output m4_includes for local M4 files, we recommend
872 that you clean up your setup, removing all manual m4_includes and
873 letting aclocal output them.
875 - Output detailed menus in the Info version if the Automake manual,
876 so that Emacs can locate the indexes.
878 - configure.ac and configure were listed twice in DIST_COMMON (an
879 internal variable where Automake lists configury files to
880 distribute). This was harmless, but unaesthetic.
882 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
883 This was an issue only in the Automake package itself, not in
886 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
887 DEST:SRC. This was wrong, as some packages do
888 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
891 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
892 argument. This caused two kinds of failures:
893 - Rules installing data in a conditionally defined directory
894 failed when that directory was undefined. In this case no
895 argument was supplied.
896 - `make installdirs' failed, because several directories were
897 passed to $(mkdir_p). This was an issue only on platform
898 were $(mkdir_p) is implemented with `install-sh -d'.
899 $(mkdir_p) as been changed to accept 0 or more arguments, as
902 * Long-standing bugs:
904 - Fix an unexpected diagnostic occurring when users attempt
905 to override some internal variables that Automake appends to.
907 - aclocal now scans configure.ac for macro definitions (PR/319).
909 - Fix a portability issue with OSF1/Tru64 Make. If a directory
910 distributes files which are outside itself (this usually occurs
911 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
912 from a parent package), then `make distcheck' fails due to an
913 optimization performed by OSF1/Tru64 Make in its VPATH handling.
914 (tests/subpkg2.test failure)
916 - Fix another portability issue with Sun and OSF1/Tru64 Make.
917 In a VPATH-build configuration, `make install' would install
918 nobase_ files to wrong locations.
920 - Fix a Perl `uninitialized value' diagnostic occurring when
921 automake complains that a Texinfo file does not have a
922 @setfilename statement.
924 - Erase config.status.lineno during `make distclean'. This file
925 can be created by config.status. Automake already knew about
926 configure.lineno, but forgot config.status.lineno.
928 - Distribute all files, even those which are built and installed
929 conditionally. This change affects files listed in conditionally
930 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
931 as well as those listed in conditionally defined dist_*_DATA,
932 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
934 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
935 doesn't conform to POSIX.
937 - Normalize help strings for configure variables and options added
942 - Check for python2.4 in AM_PATH_PYTHON.
944 * Spurious failures in test suite:
946 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
947 tests/ltconv.test: fix failures with CVS Libtool.
948 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
949 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
950 fix failures with old Texinfo versions.
956 - The NEWS file is more verbose.
960 - Autoconf 2.58 or greater is required.
964 - Default source file names in the absence of a _SOURCES declaration
965 are made by removing any target extension before appending `.c', so
966 to make the libtool module `foo.la' from `foo.c', you only need to
969 lib_LTLIBRARIES = foo.la
970 foo_la_LDFLAGS = -module
972 For backward compatibility, foo_la.c will be used instead of
973 foo.c if this file exists or is the explicit target of a rule.
974 However -Wobsolete will warn about this deprecated naming.
976 - AR's `cru' flags are now set in a global ARFLAGS variable instead
977 of being hard-coded in each $(AR) invocation, so they can be
978 substituted from configure.ac. This has been requested by people
979 dealing with non-POSIX ar implementations.
981 - New warning option: -Woverride. This will warn about any user
982 target or variable definitions which override Automake
985 - Texinfo rules back up and restore info files when makeinfo fails.
987 - Texinfo rules now support the `html' target.
988 Running this requires Texinfo 4.0 or greater.
990 `html' is a new recursive target, so if your package mixes
991 hand-crafted `Makefile.in's with Automake-generated
992 `Makefile.in's, you should adjust the former to support (or
993 ignore) this target so that `make html' recurses successfully. If
994 you had a custom `html' rule in your `Makefile.am', it's better to
995 rename it as `html-local', otherwise your rule will override
996 Automake's new rule (you can check that by running `automake
997 -Woverride') and that will stop the recursion to subdirectories.
999 Last but not least, this `html' rule is declared PHONY, even when
1000 overridden. Fortunately, it appears that few packages use a
1001 non-PHONY `html' rule.
1003 - Any file which is m4_included from configure.ac will appear as a
1004 configure and Makefile.in dependency, and will be automatically
1007 - The rules for rebuilding Makefiles and Makefile.ins will now
1008 rebuild all Makefiles and all Makefile.ins at once when one of
1009 configure's dependencies has changed. This is considerably faster
1010 than previous implementations, where config.status and automake
1011 were run separately in each directory (this still happens when you
1012 change a Makefile.am locally, without touching configure.ac or
1013 friends). Doing this also solves a longstanding issue: these
1014 rebuild rules failed to work when adding new directories to the
1015 tree, forcing you to run automake manually.
1017 - For similar reasons, the rules to rebuild configure,
1018 config.status, and aclocal.m4 are now defined in all directories.
1019 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1020 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1021 should better define them in all directories. This is easily done
1022 using an AC_SUBST (make sure you prefix these dependencies with
1023 $(top_srcdir) since this variable will appear at different
1024 levels of the build tree).
1026 - aclocal will now use `m4_include' instead of copying local m4
1027 files into aclocal.m4. (Local m4 files are those you ship with
1028 your project, other files will be copied as usual.)
1030 Because m4_included files are automatically distributed, it means
1031 for most projects there is no point in EXTRA_DISTing the list of
1032 m4 files which are used. (You can probably get rid of
1033 m4/Makefile.am if you had one.)
1035 - aclocal will avoid touching aclocal.m4 when possible, so that
1036 Autom4te's cache isn't needlessly invalidated. This behavior can
1037 be switched off with the new `--force' option.
1039 - aclocal now uses Autoconf's --trace to detect macros which are
1040 actually used and will no longer include unused macros simply
1041 because they where mentioned. This was often the case for macros
1042 called conditionally.
1044 - New options no-dist and no-dist-gzip.
1046 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1047 py-compile, and ylwrap, now all understand --version and --help.
1049 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1050 links as part of the distclean target and including source files in
1053 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1054 argument. The latter can be used to override the default behavior
1055 (which is to abort).
1057 - Automake will exit with $? = 63 on version mismatch. (So does
1058 Autoconf 2.58) missing knows this, and in this case it will
1059 emulate the tools as if they were absent. Because older versions
1060 of Automake and Autoconf did not use this exit code, this change
1061 will only be useful in projects generated with future versions of
1064 - When using AC_CONFIG_FILES with multiple input files, Automake
1065 generates the first ".in" input file for which a ".am" exists.
1066 (Former versions would try to use only the first input file.)
1068 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1069 idiom to disable byte-compilation of lisp_LISP files, it is
1070 recommended that you switch to using lisp_DATA. Note that
1071 this is not strictly equivalent: lisp_DATA will install elisp
1072 files even if emacs is not installed, while *_LISP do not
1073 install anything unless emacs is found.
1075 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1076 available. This selection is achieved through the Makefile
1077 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1078 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1079 `$(install_sh) -m 0755 -d'.
1083 - Because `mkdir -p' is available on most platforms, and we can use
1084 `install-sh -d' when it is not, the use of the mkinstalldirs
1085 script is being phased out. `automake --add-missing' no longer
1086 installs it, and if you remove mkinstalldirs from your package,
1087 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1089 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1090 gettextize and autopoint will install it when needed. Automake
1091 will continue to define the $(mkinstalldirs) and to distribute
1092 mkinstalldirs when this script is in the source tree.
1094 - AM_PROG_CC_STDC is now empty. The content of this macro was
1095 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1096 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1097 renaming should be safe, even if you have to support several,
1098 versions of Automake, because AC_PROG_CC defines this variable
1099 since Autoconf 2.54.)
1101 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1102 variable to override the aclocal.m4 dependencies computed
1103 (inaccurately) by older versions of Automake. Because Automake
1104 now tracks configure's m4 dependencies accurately (see m4_include
1105 above), the use of ACLOCAL_M4_SOURCES should be considered
1106 obsolete and will be flagged as such when running `automake
1111 - Defining programs conditionally using Automake conditionals no
1112 longer leads to a combinatorial explosion. The following
1113 construct used to be troublesome when used with dozens of
1128 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1130 - Due to implementation constraints, previous versions of Automake
1131 proscribed multiple conditional definitions of some variables
1141 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1142 This restriction has been lifted, and these variables now
1143 support multiple conditional definitions as do other variables.
1145 - Cleanup the definitions of $(distdir) and $(top_distdir).
1146 $(top_distdir) now points to the root of the distribution
1147 directory created during `make dist', as it did in Automake 1.4,
1148 not to the root of the build tree as it did in intervening
1149 versions. Furthermore these two variables are now only defined in
1150 the top level Makefile, and passed to sub-directories when running
1153 - The --no-force option now correctly checks the Makefile.in's
1154 dependencies before deciding not to update it.
1156 - Do not assume that make files are called Makefile in cleaning rules.
1158 - Update .info files in the source tree, not in the build tree. This
1159 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1160 used to update these files in the build tree (previous versions did
1161 it in the source tree too), and it caused several problems, varying
1162 from mere annoyance to portability issues.
1164 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1165 when --add-missing and --force-missing are used. For backward
1166 compatibility --add-missing will continue to install COPYING (in
1167 `gnu' strictness) when none of these three files exist, but this
1168 use is deprecated: you should better choose a license yourself and
1169 install it once for all in your source tree (and in your code
1172 - Fix ylwrap so that it does not overwrite header files that haven't
1173 changed, as the inline rule already does.
1175 - User-defined rules override automake-defined rules for the same
1176 targets, even when rules do not have commands. This is not new
1177 (and was documented), however some of the automake-generated
1178 rules have escaped this principle in former Automake versions.
1179 Rules for the following targets are affected by this fix:
1181 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1182 info, info-am, install-data-am, install-exec-am, install-info,
1183 install-info-am, install-man, installcheck-am, maintainer-clean,
1184 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1185 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1187 Practically it means that an attempt to supplement the dependencies
1188 of some target, as in
1190 clean: my-clean-rule
1192 will now *silently override* the automake definition of the
1193 rule for this target. Running `automake -Woverride' will diagnose
1194 all such overriding definitions.
1196 It should be noted that almost all these targets support a *-local
1197 variant that is meant to supplement the automake-defined rule
1198 (See node `Extending' in the manual). The above rule should
1201 clean-local: my-clean-rule
1203 These *-local targets have been documented since at least
1204 Automake 1.2, so you should not fear the change if you have
1205 to support multiple automake versions.
1209 - The Automake manual is now distributed under the terms of the GNU FDL.
1211 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1213 - core dumps are no longer removed by the cleaning rules. There are
1214 at least three reasons for this:
1215 1. These files should not be created by any build step,
1216 so their removal do not fit any of the cleaning rules.
1217 Actually, they may be precious to the developer.
1218 2. If such file is created during a build, then it's clearly a
1219 bug Automake should not hide. Not removing the file will
1220 cause `make distcheck' to complain about its presence.
1221 3. Operating systems have different naming conventions for
1222 core dump files. A core file on one system might be a
1223 completely legitimate data file on another system.
1225 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1226 defined by Automake. This means that any definition in the
1227 environment will be used, unless overridden in the Makefile.am or
1228 on the command line. The old behavior, where these variables were
1229 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1230 AC_ARG_VARing each variable from configure.ac.
1232 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1233 documented. (The is not a new feature, these variables have
1234 been there since at least Automake 1.4.)
1236 Bugs fixed in 1.7.9:
1237 * Fix install-strip to work with nobase_ binaries.
1238 * Fix renaming of #line directives in ylwrap.
1239 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1241 Bugs fixed in 1.7.8:
1242 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1243 * Fix detection of Debian's install-info, broken since version 1.5.
1244 (Debian bug #213524).
1245 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1246 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1248 Bugs fixed in 1.7.7:
1249 * The implementation of automake's --no-force option is unreliable,
1250 so this option is ignored in this version. A real fix will appear in
1251 Automake 1.8. (Debian Bug #206299)
1252 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1253 argument is given. (PR/399)
1254 * Do not warn about leading `_' in variable names, even with -Wportability.
1255 * Support user redefinitions of TEXINFO_TEX.
1256 * depcomp: support AIX Compiler version 6.
1257 * Fix missing rebuilds during `make dist' with BSD make.
1258 (Could produce tarballs containing out-of-date files.)
1259 * Resurrect multilib support.
1260 * Noteworthy manual updates:
1261 - Extending aclocal: how to write m4 macros that won't trigger warnings
1263 - A Shared Library: Rewrite and split into subsections.
1265 Bugs fixed in 1.7.6:
1266 * Fix depcomp's icc mode for ICC 7.1.

1268 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1269 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1270 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1271 * Remove Latin-1 characters from elisp-comp.
1272 * Update the manual's @dircategory to match the Free Software Directory.
1274 Bugs fixed in 1.7.5:

1276 (Debian bug #191717)
1277 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1278 that caused invalid Makefile.ins to be generated.
1279 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1280 * New FAQ entry: renamed objects.
1282 Bugs fixed in 1.7.4:

1284 the Emacs implementation)
1285 * Fix output of aclocal.m4 dependencies in subdirectories.
1286 * Use `mv -f' instead of `mv' in fastdep rules.
1287 * Upgrade mdate-sh to work on OS/2.
1288 * Don't byte-compile elisp files when ELCFILES is set empty.

1299 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1300 * Query distutils for `pythondir' and `pythonexecdir', instead of
1301 using an hardcoded path. This should allow builds on 64-bit
1302 distributions that usually use lib64/ instead of lib/.
1303 * AM_PATH_PYTHON will also search for python2.3.
1304 * elisp files are now built all at once instead of one by one. Besides
1305 incurring a speed-up, this is required to support interdependent elisp files.
1306 * Support for DJGPP:
1307 - `make distcheck' will now work in `_inst/' and `_build' instead
1308 of `=inst/' and `=build/'
1309 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1310 - install/uninstall `*.i[0-9][0-9]'-style info files
1311 - more changes that affect only the Automake package (not its output)
1312 * Fix some incompatibilities with upcoming perl-5.10.
1313 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1314 PACKAGE and VERSION.
1316 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1317 is troublesome with gcc and Solaris compilers. (PR/385)
1318 - makedepend mode: work with Libtool. (PR/385 too)
1320 * better support for unusual gettext setups, such as multiple po/ directories
1322 - Flag missing po/ and intl/ directories as warnings, not errors.

1334 * Correctly uninstall renamed man pages.
1335 * Do not strip escaped newline in variables defined in one condition
1336 and augmented in another condition.
1337 * Fix ansi2knr rules for LIBOBJS sources.
1338 * Clean all known Texinfo index files, not only those which appear to
1339 be used, because we cannot know wich indexes are used in included files.
1340 (PR/375, Debian Bug #168671)
1341 * Honor only the first @setfilename seen in a Texinfo file.
1342 * Treat "required file X not found" diagnostics as errors (exit status 1).
1343 * Don't complain that a required file is not found when it is a Makefile
1345 * Don't use single suffix inference rules when building `.info'-less
1346 Info files, for the sake of Solaris make.
1347 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1348 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1349 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1350 * Fix building of deansified files from subdirectories. (PR/370)
1351 * Add missing `fi' in the .c->.obj rules.
1352 * Improve install-sh to work even when names contain spaces or certain
1353 (but not all) shell metachars.
1354 * Fix the following spurious failures in the test suite:
1355 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1356 * Noteworthy manual updates:
1357 - Augment the section about BUILT_SOURCES.
1358 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1360 Bugs fixed in 1.7.1:
1361 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1363 * Aclocal should now recognize macro names containing parentheses, e.g.
1364 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1365 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1367 * Install Python files even if they were built. (PR/369)
1368 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1369 version might not be defined in the latter. (PR/358)
1370 * Reorder arguments passed to a couple of commands, so things works
1371 when POSIXLY_CORRECT=1.
1372 * Fix a regex that can cause Perl to segfault on large input.
1374 * Fix distribution of packages that have some sources defined conditionally,
1375 as in the `Conditional compilation using Automake conditionals' example
1377 * Fix spurious test suite failures on IRIX.
1378 * Don't report a required variable as undefined if it has been
1379 defined conditionally for the "right" conditions.
1380 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1381 `make distcheck' fails.
1382 * Fix distribution of included Makefile fragment, so we don't create
1383 spurious directories in the distribution. (PR/366)
1384 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1387 * Autoconf 2.54 is required.
1388 * `aclocal' and `automake' will no longer warn about obsolete
1389 configure macros. This is done by `autoconf -Wobsolete'.
1390 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1391 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1392 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1393 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1394 `configure.ac' for you.
1395 * Support for per-program and per-library `_CPPFLAGS'.
1396 * New `ctags' target (builds CTAGS files).
1397 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1398 (see `automake --help' or the manual for a list of them).
1399 * Honor the WARNINGS environment variable.
1400 * Omit the call to depcomp when using gcc3: call the compiler directly.
1401 * A new option, std-options, tests that programs support --help and --version
1402 when `make installcheck' is run. This is enabled by --gnits.
1403 * Texinfo rules now support the `ps' and `pdf' targets.
1404 * Info files are now created in the build directory, not the source directory.
1405 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1407 * `make distcheck' will enforce DESTDIR support by attempting
1409 * `+=' can be used in conditionals, even if the augmented variable
1410 was defined for another condition.
1411 * Makefile fragments (inserted with `include') are always distributed.
1412 * Use Autoconf's --trace interface to inspect configure.ac and get
1413 a more accurate view of it.
1414 * Add support for extending aclocal's default macro search path
1415 using a `dirlist' file within the aclocal directory.
1416 * automake --output-dir is deprecated.
1417 * The part of the distcheck target that checks whether uninstall actually
1418 removes all installed files has been moved in a separate target,
1419 distuninstallcheck, so it can be overridden easily.
1423 * Support for AM_INIT_GETTEXT([external])
1424 * Bug fixes, including:
1425 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1426 - nobase_ programs and scripts honor --program-transform correctly.
1427 - Erase configure.lineno during `make distclean'.

1443 - Don't choke on AM_LDFLAGS definitions.
1444 - Clean libtool objects from subdirectories.
1445 - Allow configure variables with reserved suffix and unknown prefix
1446 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1447 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1450 * Autoconf 2.52 is required.
1451 * automake no longer run libtoolize.
1452 This is the job of autoreconf (from GNU Autoconf).
1453 * `dist' generates all the archive flavors, as did `dist-all'.
1454 * `dist-gzip' generates the Gzip tar file only.
1455 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1456 explosion. Makefile.in's keep a reasonable size.
1457 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1458 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1460 * `#line' of Lex and Yacc files are properly set.
1461 * EXTRA_DIST can contain generated directories.
1462 * Support for dot-less extensions in suffix rules.
1463 * The part of the distcheck target that checks whether distclean actually
1464 cleans all built files has been moved in a separate target, distcleancheck,
1465 so it can be overridden easily.
1466 * `make distcheck' will pass additional options defined in
1467 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1468 * Fixed CDPATH portability problems, in particular for MacOS X.
1469 * Fixed handling of nobase_ targets.

1472 * Added uninstall-hook target
1473 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1474 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1475 (Note that "pkgname" is not "tarname", see the manual for details.)
1476 It is also possible to pass a list of global Automake options as
1477 first argument to this new form of AM_INIT_AUTOMAKE.
1478 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1479 to be a real assembler.
1480 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1481 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1482 * aclocal and automake are also installed with the version number
