3 * Fix Config.pm import error with old Perl versions (at least 5.005_03).
4 One symptom is that aclocal could not find its macro directory.
10 - The NEWS file is more verbose.
14 - Autoconf 2.58 or greater is required.
18 - Default source file names in the absence of a _SOURCES declaration
19 are made by removing any target extension before appending `.c', so
20 to make the libtool module `foo.la' from `foo.c', you only need to
23 lib_LTLIBRARIES = foo.la
24 foo_la_LDFLAGS = -module
26 For backward compatibility, foo_la.c will be used instead of
27 foo.c if this file exists or is the explicit target of a rule.
28 However -Wobsolete will warn about this deprecated naming.
30 - AR's `cru' flags are now set in a global ARFLAGS variable instead
31 of being hard-coded in each $(AR) invocation, so they can be
32 substituted from configure.ac. This has been requested by people
33 dealing with non-POSIX ar implementations.
35 - New warning option: -Woverride. This will warn about any user
36 target or variable definitions which override Automake
39 - Texinfo rules back up and restore info files when makeinfo fails.
41 - Texinfo rules now support the `html' target.
42 Running this requires Texinfo 4.0 or greater.
44 `html' is a new recursive target, so if your package mixes
45 hand-crafted `Makefile.in's with Automake-generated
46 `Makefile.in's, you should adjust the former to support (or
47 ignore) this target so that `make html' recurses successfully. If
48 you had a custom `html' rule in your `Makefile.am', it's better to
49 rename it as `html-local', otherwise your rule will override
50 Automake's new rule (you can check that by running `automake
51 -Woverride') and that will stop the recursion to subdirectories.
53 Last but not least, this `html' rule is declared PHONY, even when
54 overridden. Fortunately, it appears that few packages use a
55 non-PHONY `html' rule.
57 - Any file which is m4_included from configure.ac will appear as a
58 configure and Makefile.in dependency, and will be automatically
61 - The rules for rebuilding Makefiles and Makefile.ins will now
62 rebuild all Makefiles and all Makefile.ins at once when one of
63 configure's dependencies has changed. This is considerably faster
64 than previous implementations, where config.status and automake
65 were run separately in each directory (this still happens when you
66 change a Makefile.am locally, without touching configure.ac or
67 friends). Doing this also solves a longstanding issue: these
68 rebuild rules failed to work when adding new directories to the
69 tree, forcing you to run automake manually.
71 - For similar reasons, the rules to rebuild configure,
72 config.status, and aclocal.m4 are now defined in all directories.
73 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
74 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
75 should better define them in all directories. This is easily done
76 using an AC_SUBST (make sure you prefix these dependencies with
77 $(top_srcdir) since this variable will appear at different
78 levels of the build tree).
80 - aclocal will now use `m4_include' instead of copying local m4
81 files into aclocal.m4. (Local m4 files are those you ship with
82 your project, other files will be copied as usual.)
84 Because m4_included files are automatically distributed, it means
85 for most projects there is no point in EXTRA_DISTing the list of
86 m4 files which are used. (You can probably get rid of
87 m4/Makefile.am if you had one.)
89 - aclocal will avoid touching aclocal.m4 when possible, so that
90 Autom4te's cache isn't needlessly invalidated. This behavior can
91 be switched off with the new `--force' option.
93 - aclocal now uses Autoconf's --trace to detect macros which are
94 actually used and will no longer include unused macros simply
95 because they where mentioned. This was often the case for macros
98 - New options no-dist and no-dist-gzip.
100 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
101 py-compile, and ylwrap, now all understand --version and --help.
103 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
104 links as part of the distclean target and including source files in
107 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
108 argument. The latter can be used to override the default behavior
111 - Automake will exit with $? = 63 on version mismatch. (So does
112 Autoconf 2.58) missing knows this, and in this case it will
113 emulate the tools as if they were absent. Because older versions
114 of Automake and Autoconf did not use this exit code, this change
115 will only be useful in projects generated with future versions of
118 - When using AC_CONFIG_FILES with multiple input files, Automake
119 generates the first ".in" input file for which a ".am" exists.
120 (Former versions would try to use only the first input file.)
122 - lisp_DATA is now allowed. If you are using the empty ELCFILES
123 idiom to disable byte-compilation of lisp_LISP files, it is
124 recommended that you switch to using lisp_DATA. Note that
125 this is not strictly equivalent: lisp_DATA will install elisp
126 files even if emacs is not installed, while *_LISP do not
127 install anything unless emacs is found.
129 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
130 available. This selection is achieved through the Makefile
131 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
132 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
133 `$(install_sh) -m 0755 -d'.
137 - Because `mkdir -p' is available on most platforms, and we can use
138 `install-sh -d' when it is not, the use of the mkinstalldirs
139 script is being phased out. `automake --add-missing' no longer
140 installs it, and if you remove mkinstalldirs from your package,
141 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
143 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
144 gettextize and autopoint will install it when needed. Automake
145 will continue to define the $(mkinstalldirs) and to distribute
146 mkinstalldirs when this script is in the source tree.
148 - AM_PROG_CC_STDC is now empty. The content of this macro was
149 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
150 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
151 renaming should be safe, even if you have to support several,
152 versions of Automake, because AC_PROG_CC defines this variable
153 since Autoconf 2.54.)
155 - Some users where using the undocumented ACLOCAL_M4_SOURCES
156 variable to override the aclocal.m4 dependencies computed
157 (inaccurately) by older versions of Automake. Because Automake
158 now tracks configure's m4 dependencies accurately (see m4_include
159 above), the use of ACLOCAL_M4_SOURCES should be considered
160 obsolete and will be flagged as such when running `automake
165 - Defining programs conditionally using Automake conditionals no
166 longer leads to a combinatorial explosion. The following
167 construct used to be troublesome when used with dozens of
182 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
184 - Due to implementation constraints, previous versions of Automake
185 proscribed multiple conditional definitions of some variables
195 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
196 This restriction has been lifted, and these variables now
197 support multiple conditional definitions as do other variables.
199 - Cleanup the definitions of $(distdir) and $(top_distdir).
200 $(top_distdir) now points to the root of the distribution
201 directory created during `make dist', as it did in Automake 1.4,
202 not to the root of the build tree as it did in intervening
203 versions. Furthermore these two variables are now only defined in
204 the top level Makefile, and passed to sub-directories when running
207 - The --no-force option now correctly checks the Makefile.in's
208 dependencies before deciding not to update it.
210 - Do not assume that make files are called Makefile in cleaning rules.
212 - Update .info files in the source tree, not in the build tree. This
213 is what the GNU Coding Standard recommend. Only Automake 1.7.x
214 used to update these files in the build tree (previous versions did
215 it in the source tree too), and it caused several problems, varying
216 from mere annoyance to portability issues.
218 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
219 when --add-missing and --force-missing are used. For backward
220 compatibility --add-missing will continue to install COPYING (in
221 `gnu' strictness) when none of these three files exist, but this
222 use is deprecated: you should better choose a license yourself and
223 install it once for all in your source tree (and in your code
226 - Fix ylwrap so that it does not overwrite header files that haven't
227 changed, as the inline rule already does.
229 - User-defined rules override automake-defined rules for the same
230 targets, even when rules do not have commands. This is not new
231 (and was documented), however some of the automake-generated
232 rules have escaped this principle in former Automake versions.
233 Rules for the following targets are affected by this fix:
235 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
236 info, info-am, install-data-am, install-exec-am, install-info,
237 install-info-am, install-man, installcheck-am, maintainer-clean,
238 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
239 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
241 Practically it means that an attempt to supplement the dependencies
242 of some target, as in
246 will now *silently override* the automake definition of the
247 rule for this target. Running `automake -Woverride' will diagnose
248 all such overriding definitions.
250 It should be noted that almost all these targets support a *-local
251 variant that is meant to supplement the automake-defined rule
252 (See node `Extending' in the manual). The above rule should
255 clean-local: my-clean-rule
257 These *-local targets have been documented since at least
258 Automake 1.2, so you should not fear the change if you have
259 to support multiple automake versions.
263 - The Automake manual is now distributed under the terms of the GNU FDL.
265 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
267 - core dumps are no longer removed by the cleaning rules. There are
268 at least three reasons for this:
269 1. These files should not be created by any build step,
270 so their removal do not fit any of the cleaning rules.
271 Actually, they may be precious to the developer.
272 2. If such file is created during a build, then it's clearly a
273 bug Automake should not hide. Not removing the file will
274 cause `make distcheck' to complain about its presence.
275 3. Operating systems have different naming conventions for
276 core dump files. A core file on one system might be a
277 completely legitimate data file on another system.
279 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
280 defined by Automake. This means that any definition in the
281 environment will be used, unless overridden in the Makefile.am or
282 on the command line. The old behavior, where these variables were
283 defined empty in each Makefile, can be obtained by AC_SUBSTing or
284 AC_ARG_VARing each variable from configure.ac.
286 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
287 documented. (The is not a new feature, these variables have
288 been there since at least Automake 1.4.)
291 * Fix install-strip to work with nobase_ binaries.
292 * Fix renaming of #line directives in ylwrap.
293 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
296 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
297 * Fix detection of Debian's install-info, broken since version 1.5.
298 (Debian bug #213524).
299 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
300 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
303 * The implementation of automake's --no-force option is unreliable,
304 so this option is ignored in this version. A real fix will appear in
305 Automake 1.8. (Debian Bug #206299)
306 * AM_PATH_PYTHON: really check the whole list of interpreters if no
307 argument is given. (PR/399)
308 * Do not warn about leading `_' in variable names, even with -Wportability.
309 * Support user redefinitions of TEXINFO_TEX.
310 * depcomp: support AIX Compiler version 6.
311 * Fix missing rebuilds during `make dist' with BSD make.
312 (Could produce tarballs containing out-of-date files.)
313 * Resurrect multilib support.
314 * Noteworthy manual updates:
315 - Extending aclocal: how to write m4 macros that won't trigger warnings
317 - A Shared Library: Rewrite and split into subsections.
320 * Fix depcomp's icc mode for ICC 7.1.
321 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
322 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
323 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
324 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
325 * Remove Latin-1 characters from elisp-comp.
326 * Update the manual's @dircategory to match the Free Software Directory.
329 * Update install-sh's license to remove an advertising clause.
331 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
332 that caused invalid Makefile.ins to be generated.
333 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
334 * New FAQ entry: renamed objects.
337 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
338 the Emacs implementation)
339 * Fix output of aclocal.m4 dependencies in subdirectories.
340 * Use `mv -f' instead of `mv' in fastdep rules.
341 * Upgrade mdate-sh to work on OS/2.
342 * Don't byte-compile elisp files when ELCFILES is set empty.
343 (this documented feature was broken by 1.7.3)
344 * Diagnose trailing backslashes on last line of Makefile.am.
345 * Diagnose whitespace following trailing backslashes.
346 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
347 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
349 * `make install' will build `BUILT_SOURCES' first.
350 * Minor documentation fixes.
353 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
354 * Query distutils for `pythondir' and `pythonexecdir', instead of
355 using an hardcoded path. This should allow builds on 64-bit
356 distributions that usually use lib64/ instead of lib/.
357 * AM_PATH_PYTHON will also search for python2.3.
358 * elisp files are now built all at once instead of one by one. Besides
359 incurring a speed-up, this is required to support interdependent elisp files.
361 - `make distcheck' will now work in `_inst/' and `_build' instead
362 of `=inst/' and `=build/'
363 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
364 - install/uninstall `*.i[0-9][0-9]'-style info files
365 - more changes that affect only the Automake package (not its output)
366 * Fix some incompatibilities with upcoming perl-5.10.
367 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
370 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
371 is troublesome with gcc and Solaris compilers. (PR/385)
372 - makedepend mode: work with Libtool. (PR/385 too)
374 * better support for unusual gettext setups, such as multiple po/ directories
376 - Flag missing po/ and intl/ directories as warnings, not errors.
377 - Disable these warnings if po/ does not exist.
378 * Noteworthy manual updates:
380 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
382 - Document `AM_YFLAGS = -d'. (PR/382)
385 * Fix installation and uninstallation of Info files built in subdirectories.
386 * Do not run `./configure --with-included-gettext' during `make distcheck'
387 if AM_GNU_GETTEXT([external]) is used.
388 * Correctly uninstall renamed man pages.
389 * Do not strip escaped newline in variables defined in one condition
390 and augmented in another condition.
391 * Fix ansi2knr rules for LIBOBJS sources.
392 * Clean all known Texinfo index files, not only those which appear to
393 be used, because we cannot know wich indexes are used in included files.
394 (PR/375, Debian Bug #168671)
395 * Honor only the first @setfilename seen in a Texinfo file.
396 * Treat "required file X not found" diagnostics as errors (exit status 1).
397 * Don't complain that a required file is not found when it is a Makefile
399 * Don't use single suffix inference rules when building `.info'-less
400 Info files, for the sake of Solaris make.
401 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
402 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
403 * Warn about multiple inference rules when -Wportability is used. (PR/372)
404 * Fix building of deansified files from subdirectories. (PR/370)
405 * Add missing `fi' in the .c->.obj rules.
406 * Improve install-sh to work even when names contain spaces or certain
407 (but not all) shell metachars.
408 * Fix the following spurious failures in the test suite:
409 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
410 * Noteworthy manual updates:
411 - Augment the section about BUILT_SOURCES.
412 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
415 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
417 * Aclocal should now recognize macro names containing parentheses, e.g.
418 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
419 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
421 * Install Python files even if they were built. (PR/369)
422 * Have stamp-vti dependent upon configure instead of configure.ac, as the
423 version might not be defined in the latter. (PR/358)
424 * Reorder arguments passed to a couple of commands, so things works
425 when POSIXLY_CORRECT=1.
426 * Fix a regex that can cause Perl to segfault on large input.
428 * Fix distribution of packages that have some sources defined conditionally,
429 as in the `Conditional compilation using Automake conditionals' example
431 * Fix spurious test suite failures on IRIX.
432 * Don't report a required variable as undefined if it has been
433 defined conditionally for the "right" conditions.
434 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
435 `make distcheck' fails.
436 * Fix distribution of included Makefile fragment, so we don't create
437 spurious directories in the distribution. (PR/366)
438 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
441 * Autoconf 2.54 is required.
442 * `aclocal' and `automake' will no longer warn about obsolete
443 configure macros. This is done by `autoconf -Wobsolete'.
444 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
445 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
446 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
447 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
448 `configure.ac' for you.
449 * Support for per-program and per-library `_CPPFLAGS'.
450 * New `ctags' target (builds CTAGS files).
451 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
452 (see `automake --help' or the manual for a list of them).
453 * Honor the WARNINGS environment variable.
454 * Omit the call to depcomp when using gcc3: call the compiler directly.
455 * A new option, std-options, tests that programs support --help and --version
456 when `make installcheck' is run. This is enabled by --gnits.
457 * Texinfo rules now support the `ps' and `pdf' targets.
458 * Info files are now created in the build directory, not the source directory.
459 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
461 * `make distcheck' will enforce DESTDIR support by attempting
463 * `+=' can be used in conditionals, even if the augmented variable
464 was defined for another condition.
465 * Makefile fragments (inserted with `include') are always distributed.
466 * Use Autoconf's --trace interface to inspect configure.ac and get
467 a more accurate view of it.
468 * Add support for extending aclocal's default macro search path
469 using a `dirlist' file within the aclocal directory.
470 * automake --output-dir is deprecated.
471 * The part of the distcheck target that checks whether uninstall actually
472 removes all installed files has been moved in a separate target,
473 distuninstallcheck, so it can be overridden easily.
477 * Support for AM_INIT_GETTEXT([external])
478 * Bug fixes, including:
479 - Fix Automake's own `make install' so it works even if `ln' doesn't.
480 - nobase_ programs and scripts honor --program-transform correctly.
481 - Erase configure.lineno during `make distclean'.
482 - Erase YACC and LEX outputs during `make maintainer-clean'.
485 * Many bug fixes, including:
486 - Requiring the current version works.
487 - Fix "$@" portability issues (for Zsh).
488 - Fix output of dummy dependency files in presence of post-processed
490 - Don't compute dependencies in background to avoid races with libtool.
491 - Fix handling of _OBJECTS variables for targets sharing source variables.
492 - Check dependency mode for Java when AM_PROG_GCJ is used.
495 * automake --output-dir is deprecated
496 * Many bug fixes, including:
497 - Don't choke on AM_LDFLAGS definitions.
498 - Clean libtool objects from subdirectories.
499 - Allow configure variables with reserved suffix and unknown prefix
500 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
501 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
504 * Autoconf 2.52 is required.
505 * automake no longer run libtoolize.
506 This is the job of autoreconf (from GNU Autoconf).
507 * `dist' generates all the archive flavors, as did `dist-all'.
508 * `dist-gzip' generates the Gzip tar file only.
509 * Combining Automake Makefile conditionals no longer lead to a combinatorial
510 explosion. Makefile.in's keep a reasonable size.
511 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
512 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
514 * `#line' of Lex and Yacc files are properly set.
515 * EXTRA_DIST can contain generated directories.
516 * Support for dot-less extensions in suffix rules.
517 * The part of the distcheck target that checks whether distclean actually
518 cleans all built files has been moved in a separate target, distcleancheck,
519 so it can be overridden easily.
520 * `make distcheck' will pass additional options defined in
521 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
522 * Fixed CDPATH portability problems, in particular for MacOS X.
523 * Fixed handling of nobase_ targets.
524 * Fixed support of implicit rules leading to .lo objects.
525 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
526 * Added uninstall-hook target
527 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
528 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
529 (Note that "pkgname" is not "tarname", see the manual for details.)
530 It is also possible to pass a list of global Automake options as
531 first argument to this new form of AM_INIT_AUTOMAKE.
532 * Compiler-based assembler is now called `CCAS'; people expected `AS'
533 to be a real assembler.
534 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
535 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
536 * aclocal and automake are also installed with the version number
537 appended, and some of the install directory names have changed.
538 This lets you have multiple versions installed simultaneously.
539 * Support for parsers and lexers in subdirectories.
542 * Support for `configure.ac'.
543 * Support for `else COND', `endif COND' and negated conditions `!COND'.
544 * `make dist-all' is much faster.
545 * Allows '@' AC_SUBSTs in macro names.
546 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
547 * User-side dependency tracking. Developers no longer need GNU make
549 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
550 * Most files are correctly handled if they appear in subdirs
551 For instance, a _DATA file can appear in a subdir
552 * GNU tar is no longer required for `make dist'
553 * Added support for `dist_' and `nodist_' prefixes
554 * Added support for `nobase_' prefix
555 * Compiled Java support
556 * Support for per-executable and per-library compilation flags
560 * Added support for the Fortran 77 programming language.
561 * Re-indexed the Automake Texinfo manual.
562 * Added `AM_FOOFLAGS' variable for each compiler invocation;
563 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
564 * Support for latest autoconf, including support for objext
