3 * Libtool tags are used with libtool versions that support them.
4 (I.e., with Libtool 1.5 or greater.)
6 * Makefile.in bloat reduction.
8 - Inference rules are used to compile sources in subdirectories when
9 the `subdir-objects' option is used and no per-target flags are
10 used. This should reduce the size of some projects a lot, because
11 Automake used to output an explicit rule for each such object in
14 - Automake no longer outputs three rules (.o, .obj, .lo) for each
15 object that must be built with explicit rules. It just outputs
16 the rules required to build the kind of object considered: either
17 the two .o and .obj rules for usual objects, or the .lo rule for
20 * Support for conditional _LISP.
27 - The NEWS file is more verbose.
31 - Autoconf 2.58 or greater is required.
35 - Default source file names in the absence of a _SOURCES declaration
36 are made by removing any target extension before appending `.c', so
37 to make the libtool module `foo.la' from `foo.c', you only need to
40 lib_LTLIBRARIES = foo.la
41 foo_la_LDFLAGS = -module
43 For backward compatibility, foo_la.c will be used instead of
44 foo.c if this file exists or is the explicit target of a rule.
45 However -Wobsolete will warn about this deprecated naming.
47 - AR's `cru' flags are now set in a global ARFLAGS variable instead
48 of being hard-coded in each $(AR) invocation, so they can be
49 substituted from configure.ac. This has been requested by people
50 dealing with non-POSIX ar implementations.
52 - New warning option: -Woverride. This will warn about any user
53 target or variable definitions which override Automake
56 - Texinfo rules back up and restore info files when makeinfo fails.
58 - Texinfo rules now support the `html' target.
59 Running this requires Texinfo 4.0 or greater.
61 `html' is a new recursive target, so if your package mixes
62 hand-crafted `Makefile.in's with Automake-generated
63 `Makefile.in's, you should adjust the former to support (or
64 ignore) this target so that `make html' recurses successfully. If
65 you had a custom `html' rule in your `Makefile.am', it's better to
66 rename it as `html-local', otherwise your rule will override
67 Automake's new rule (you can check that by running `automake
68 -Woverride') and that will stop the recursion to subdirectories.
70 Last but not least, this `html' rule is declared PHONY, even when
71 overridden. Fortunately, it appears that few packages use a
72 non-PHONY `html' rule.
74 - Any file which is m4_included from configure.ac will appear as a
75 configure and Makefile.in dependency, and will be automatically
78 - The rules for rebuilding Makefiles and Makefile.ins will now
79 rebuild all Makefiles and all Makefile.ins at once when one of
80 configure's dependencies has changed. This is considerably faster
81 than previous implementations, where config.status and automake
82 were run separately in each directory (this still happens when you
83 change a Makefile.am locally, without touching configure.ac or
84 friends). Doing this also solves a longstanding issue: these
85 rebuild rules failed to work when adding new directories to the
86 tree, forcing you to run automake manually.
88 - For similar reasons, the rules to rebuild configure,
89 config.status, and aclocal.m4 are now defined in all directories.
90 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
91 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
92 should better define them in all directories. This is easily done
93 using an AC_SUBST (make sure you prefix these dependencies with
94 $(top_srcdir) since this variable will appear at different
95 levels of the build tree).
97 - aclocal will now use `m4_include' instead of copying local m4
98 files into aclocal.m4. (Local m4 files are those you ship with
99 your project, other files will be copied as usual.)
101 Because m4_included files are automatically distributed, it means
102 for most projects there is no point in EXTRA_DISTing the list of
103 m4 files which are used. (You can probably get rid of
104 m4/Makefile.am if you had one.)
106 - aclocal will avoid touching aclocal.m4 when possible, so that
107 Autom4te's cache isn't needlessly invalidated. This behavior can
108 be switched off with the new `--force' option.
110 - aclocal now uses Autoconf's --trace to detect macros which are
111 actually used and will no longer include unused macros simply
112 because they where mentioned. This was often the case for macros
113 called conditionally.
115 - New options no-dist and no-dist-gzip.
117 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
118 py-compile, and ylwrap, now all understand --version and --help.
120 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
121 links as part of the distclean target and including source files in
124 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
125 argument. The latter can be used to override the default behavior
128 - Automake will exit with $? = 63 on version mismatch. (So does
129 Autoconf 2.58) missing knows this, and in this case it will
130 emulate the tools as if they were absent. Because older versions
131 of Automake and Autoconf did not use this exit code, this change
132 will only be useful in projects generated with future versions of
135 - When using AC_CONFIG_FILES with multiple input files, Automake
136 generates the first ".in" input file for which a ".am" exists.
137 (Former versions would try to use only the first input file.)
139 - lisp_DATA is now allowed. If you are using the empty ELCFILES
140 idiom to disable byte-compilation of lisp_LISP files, it is
141 recommended that you switch to using lisp_DATA. Note that
142 this is not strictly equivalent: lisp_DATA will install elisp
143 files even if emacs is not installed, while *_LISP do not
144 install anything unless emacs is found.
146 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
147 available. This selection is achieved through the Makefile
148 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
149 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
150 `$(install_sh) -m 0755 -d'.
154 - Because `mkdir -p' is available on most platforms, and we can use
155 `install-sh -d' when it is not, the use of the mkinstalldirs
156 script is being phased out. `automake --add-missing' no longer
157 installs it, and if you remove mkinstalldirs from your package,
158 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
160 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
161 gettextize and autopoint will install it when needed. Automake
162 will continue to define the $(mkinstalldirs) and to distribute
163 mkinstalldirs when this script is in the source tree.
165 - AM_PROG_CC_STDC is now empty. The content of this macro was
166 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
167 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
168 renaming should be safe, even if you have to support several,
169 versions of Automake, because AC_PROG_CC defines this variable
170 since Autoconf 2.54.)
172 - Some users where using the undocumented ACLOCAL_M4_SOURCES
173 variable to override the aclocal.m4 dependencies computed
174 (inaccurately) by older versions of Automake. Because Automake
175 now tracks configure's m4 dependencies accurately (see m4_include
176 above), the use of ACLOCAL_M4_SOURCES should be considered
177 obsolete and will be flagged as such when running `automake
182 - Defining programs conditionally using Automake conditionals no
183 longer leads to a combinatorial explosion. The following
184 construct used to be troublesome when used with dozens of
199 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
201 - Due to implementation constraints, previous versions of Automake
202 proscribed multiple conditional definitions of some variables
212 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
213 This restriction has been lifted, and these variables now
214 support multiple conditional definitions as do other variables.
216 - Cleanup the definitions of $(distdir) and $(top_distdir).
217 $(top_distdir) now points to the root of the distribution
218 directory created during `make dist', as it did in Automake 1.4,
219 not to the root of the build tree as it did in intervening
220 versions. Furthermore these two variables are now only defined in
221 the top level Makefile, and passed to sub-directories when running
224 - The --no-force option now correctly checks the Makefile.in's
225 dependencies before deciding not to update it.
227 - Do not assume that make files are called Makefile in cleaning rules.
229 - Update .info files in the source tree, not in the build tree. This
230 is what the GNU Coding Standard recommend. Only Automake 1.7.x
231 used to update these files in the build tree (previous versions did
232 it in the source tree too), and it caused several problems, varying
233 from mere annoyance to portability issues.
235 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
236 when --add-missing and --force-missing are used. For backward
237 compatibility --add-missing will continue to install COPYING (in
238 `gnu' strictness) when none of these three files exist, but this
239 use is deprecated: you should better choose a license yourself and
240 install it once for all in your source tree (and in your code
243 - Fix ylwrap so that it does not overwrite header files that haven't
244 changed, as the inline rule already does.
246 - User-defined rules override automake-defined rules for the same
247 targets, even when rules do not have commands. This is not new
248 (and was documented), however some of the automake-generated
249 rules have escaped this principle in former Automake versions.
250 Rules for the following targets are affected by this fix:
252 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
253 info, info-am, install-data-am, install-exec-am, install-info,
254 install-info-am, install-man, installcheck-am, maintainer-clean,
255 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
256 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
258 Practically it means that an attempt to supplement the dependencies
259 of some target, as in
263 will now *silently override* the automake definition of the
264 rule for this target. Running `automake -Woverride' will diagnose
265 all such overriding definitions.
267 It should be noted that almost all these targets support a *-local
268 variant that is meant to supplement the automake-defined rule
269 (See node `Extending' in the manual). The above rule should
272 clean-local: my-clean-rule
274 These *-local targets have been documented since at least
275 Automake 1.2, so you should not fear the change if you have
276 to support multiple automake versions.
280 - The Automake manual is now distributed under the terms of the GNU FDL.
282 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
284 - core dumps are no longer removed by the cleaning rules. There are
285 at least three reasons for this:
286 1. These files should not be created by any build step,
287 so their removal do not fit any of the cleaning rules.
288 Actually, they may be precious to the developer.
289 2. If such file is created during a build, then it's clearly a
290 bug Automake should not hide. Not removing the file will
291 cause `make distcheck' to complain about its presence.
292 3. Operating systems have different naming conventions for
293 core dump files. A core file on one system might be a
294 completely legitimate data file on another system.
296 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
297 defined by Automake. This means that any definition in the
298 environment will be used, unless overridden in the Makefile.am or
299 on the command line. The old behavior, where these variables were
300 defined empty in each Makefile, can be obtained by AC_SUBSTing or
301 AC_ARG_VARing each variable from configure.ac.
303 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
304 documented. (The is not a new feature, these variables have
305 been there since at least Automake 1.4.)
308 * Fix install-strip to work with nobase_ binaries.
309 * Fix renaming of #line directives in ylwrap.
310 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
313 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
314 * Fix detection of Debian's install-info, broken since version 1.5.
315 (Debian bug #213524).
316 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
317 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
320 * The implementation of automake's --no-force option is unreliable,
321 so this option is ignored in this version. A real fix will appear in
322 Automake 1.8. (Debian Bug #206299)
323 * AM_PATH_PYTHON: really check the whole list of interpreters if no
324 argument is given. (PR/399)
325 * Do not warn about leading `_' in variable names, even with -Wportability.
326 * Support user redefinitions of TEXINFO_TEX.
327 * depcomp: support AIX Compiler version 6.
328 * Fix missing rebuilds during `make dist' with BSD make.
329 (Could produce tarballs containing out-of-date files.)
330 * Resurrect multilib support.
331 * Noteworthy manual updates:
332 - Extending aclocal: how to write m4 macros that won't trigger warnings
334 - A Shared Library: Rewrite and split into subsections.
337 * Fix depcomp's icc mode for ICC 7.1.
338 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
339 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
340 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
341 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
342 * Remove Latin-1 characters from elisp-comp.
343 * Update the manual's @dircategory to match the Free Software Directory.
346 * Update install-sh's license to remove an advertising clause.
348 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
349 that caused invalid Makefile.ins to be generated.
350 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
351 * New FAQ entry: renamed objects.
354 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
355 the Emacs implementation)
356 * Fix output of aclocal.m4 dependencies in subdirectories.
357 * Use `mv -f' instead of `mv' in fastdep rules.
358 * Upgrade mdate-sh to work on OS/2.
359 * Don't byte-compile elisp files when ELCFILES is set empty.
360 (this documented feature was broken by 1.7.3)
361 * Diagnose trailing backslashes on last line of Makefile.am.
362 * Diagnose whitespace following trailing backslashes.
363 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
364 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
366 * `make install' will build `BUILT_SOURCES' first.
367 * Minor documentation fixes.
370 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
371 * Query distutils for `pythondir' and `pythonexecdir', instead of
372 using an hardcoded path. This should allow builds on 64-bit
373 distributions that usually use lib64/ instead of lib/.
374 * AM_PATH_PYTHON will also search for python2.3.
375 * elisp files are now built all at once instead of one by one. Besides
376 incurring a speed-up, this is required to support interdependent elisp files.
378 - `make distcheck' will now work in `_inst/' and `_build' instead
379 of `=inst/' and `=build/'
380 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
381 - install/uninstall `*.i[0-9][0-9]'-style info files
382 - more changes that affect only the Automake package (not its output)
383 * Fix some incompatibilities with upcoming perl-5.10.
384 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
387 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
388 is troublesome with gcc and Solaris compilers. (PR/385)
389 - makedepend mode: work with Libtool. (PR/385 too)
391 * better support for unusual gettext setups, such as multiple po/ directories
393 - Flag missing po/ and intl/ directories as warnings, not errors.
394 - Disable these warnings if po/ does not exist.
395 * Noteworthy manual updates:
397 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
399 - Document `AM_YFLAGS = -d'. (PR/382)
402 * Fix installation and uninstallation of Info files built in subdirectories.
403 * Do not run `./configure --with-included-gettext' during `make distcheck'
404 if AM_GNU_GETTEXT([external]) is used.
405 * Correctly uninstall renamed man pages.
406 * Do not strip escaped newline in variables defined in one condition
407 and augmented in another condition.
408 * Fix ansi2knr rules for LIBOBJS sources.
409 * Clean all known Texinfo index files, not only those which appear to
410 be used, because we cannot know wich indexes are used in included files.
411 (PR/375, Debian Bug #168671)
412 * Honor only the first @setfilename seen in a Texinfo file.
413 * Treat "required file X not found" diagnostics as errors (exit status 1).
414 * Don't complain that a required file is not found when it is a Makefile
416 * Don't use single suffix inference rules when building `.info'-less
417 Info files, for the sake of Solaris make.
418 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
419 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
420 * Warn about multiple inference rules when -Wportability is used. (PR/372)
421 * Fix building of deansified files from subdirectories. (PR/370)
422 * Add missing `fi' in the .c->.obj rules.
423 * Improve install-sh to work even when names contain spaces or certain
424 (but not all) shell metachars.
425 * Fix the following spurious failures in the test suite:
426 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
427 * Noteworthy manual updates:
428 - Augment the section about BUILT_SOURCES.
429 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
432 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
434 * Aclocal should now recognize macro names containing parentheses, e.g.
435 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
436 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
438 * Install Python files even if they were built. (PR/369)
439 * Have stamp-vti dependent upon configure instead of configure.ac, as the
440 version might not be defined in the latter. (PR/358)
441 * Reorder arguments passed to a couple of commands, so things works
442 when POSIXLY_CORRECT=1.
443 * Fix a regex that can cause Perl to segfault on large input.
445 * Fix distribution of packages that have some sources defined conditionally,
446 as in the `Conditional compilation using Automake conditionals' example
448 * Fix spurious test suite failures on IRIX.
449 * Don't report a required variable as undefined if it has been
450 defined conditionally for the "right" conditions.
451 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
452 `make distcheck' fails.
453 * Fix distribution of included Makefile fragment, so we don't create
454 spurious directories in the distribution. (PR/366)
455 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
458 * Autoconf 2.54 is required.
459 * `aclocal' and `automake' will no longer warn about obsolete
460 configure macros. This is done by `autoconf -Wobsolete'.
461 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
462 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
463 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
464 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
465 `configure.ac' for you.
466 * Support for per-program and per-library `_CPPFLAGS'.
467 * New `ctags' target (builds CTAGS files).
468 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
469 (see `automake --help' or the manual for a list of them).
470 * Honor the WARNINGS environment variable.
471 * Omit the call to depcomp when using gcc3: call the compiler directly.
472 * A new option, std-options, tests that programs support --help and --version
473 when `make installcheck' is run. This is enabled by --gnits.
474 * Texinfo rules now support the `ps' and `pdf' targets.
475 * Info files are now created in the build directory, not the source directory.
476 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
478 * `make distcheck' will enforce DESTDIR support by attempting
480 * `+=' can be used in conditionals, even if the augmented variable
481 was defined for another condition.
482 * Makefile fragments (inserted with `include') are always distributed.
483 * Use Autoconf's --trace interface to inspect configure.ac and get
484 a more accurate view of it.
485 * Add support for extending aclocal's default macro search path
486 using a `dirlist' file within the aclocal directory.
487 * automake --output-dir is deprecated.
488 * The part of the distcheck target that checks whether uninstall actually
489 removes all installed files has been moved in a separate target,
490 distuninstallcheck, so it can be overridden easily.
494 * Support for AM_INIT_GETTEXT([external])
495 * Bug fixes, including:
496 - Fix Automake's own `make install' so it works even if `ln' doesn't.
497 - nobase_ programs and scripts honor --program-transform correctly.
498 - Erase configure.lineno during `make distclean'.
499 - Erase YACC and LEX outputs during `make maintainer-clean'.
502 * Many bug fixes, including:
503 - Requiring the current version works.
504 - Fix "$@" portability issues (for Zsh).
505 - Fix output of dummy dependency files in presence of post-processed
507 - Don't compute dependencies in background to avoid races with libtool.
508 - Fix handling of _OBJECTS variables for targets sharing source variables.
509 - Check dependency mode for Java when AM_PROG_GCJ is used.
512 * automake --output-dir is deprecated
513 * Many bug fixes, including:
514 - Don't choke on AM_LDFLAGS definitions.
515 - Clean libtool objects from subdirectories.
516 - Allow configure variables with reserved suffix and unknown prefix
517 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
518 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
521 * Autoconf 2.52 is required.
522 * automake no longer run libtoolize.
523 This is the job of autoreconf (from GNU Autoconf).
524 * `dist' generates all the archive flavors, as did `dist-all'.
525 * `dist-gzip' generates the Gzip tar file only.
526 * Combining Automake Makefile conditionals no longer lead to a combinatorial
527 explosion. Makefile.in's keep a reasonable size.
528 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
529 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
531 * `#line' of Lex and Yacc files are properly set.
532 * EXTRA_DIST can contain generated directories.
533 * Support for dot-less extensions in suffix rules.
534 * The part of the distcheck target that checks whether distclean actually
535 cleans all built files has been moved in a separate target, distcleancheck,
536 so it can be overridden easily.
537 * `make distcheck' will pass additional options defined in
538 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
539 * Fixed CDPATH portability problems, in particular for MacOS X.
540 * Fixed handling of nobase_ targets.
541 * Fixed support of implicit rules leading to .lo objects.
542 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
543 * Added uninstall-hook target
544 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
545 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
546 (Note that "pkgname" is not "tarname", see the manual for details.)
547 It is also possible to pass a list of global Automake options as
548 first argument to this new form of AM_INIT_AUTOMAKE.
549 * Compiler-based assembler is now called `CCAS'; people expected `AS'
550 to be a real assembler.
551 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
552 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
553 * aclocal and automake are also installed with the version number
554 appended, and some of the install directory names have changed.
555 This lets you have multiple versions installed simultaneously.
556 * Support for parsers and lexers in subdirectories.
559 * Support for `configure.ac'.
560 * Support for `else COND', `endif COND' and negated conditions `!COND'.
561 * `make dist-all' is much faster.
562 * Allows '@' AC_SUBSTs in macro names.
563 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
564 * User-side dependency tracking. Developers no longer need GNU make
566 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
567 * Most files are correctly handled if they appear in subdirs
