5 - The NEWS file is more verbose.
9 - Autoconf 2.58 or greater is required.
13 - Default source file names in the absence of a _SOURCES declaration
14 are made by removing any target extension before appending `.c', so
15 to make the libtool module `foo.la' from `foo.c', you only need to
18 lib_LTLIBRARIES = foo.la
19 foo_la_LDFLAGS = -module
21 For backward compatibility, foo_la.c will be used instead of
22 foo.c if this file exists or is the explicit target of a rule.
23 However -Wobsolete will warn about this deprecated naming.
25 - AR's `cru' flags are now set in a global ARFLAGS variable instead
26 of being hard-coded in each $(AR) invocation, so they can be
27 substituted from configure.ac. This has been requested by people
28 dealing with non-POSIX ar implementations.
30 - New warning option: -Woverride. This will warn about any user
31 target or variable definitions which override Automake
34 - Texinfo rules back up and restore info files when makeinfo fails.
36 - Texinfo rules now support the `html' target.
37 Running this requires Texinfo 4.0 or greater.
39 `html' is a new recursive target, so if your package mixes
40 hand-crafted `Makefile.in's with Automake-generated
41 `Makefile.in's, you should adjust the former to support (or
42 ignore) this target so that `make html' recurses successfully. If
43 you had a custom `html' rule in your `Makefile.am', it's better to
44 rename it as `html-local', otherwise your rule will override
45 Automake's new rule (you can check that by running `automake
46 -Woverride') and that will stop the recursion to subdirectories.
48 Last but not least, this `html' rule is declared PHONY, even when
49 overridden. Fortunately, it appears that few packages use a
50 non-PHONY `html' rule.
52 - Any file which is m4_included from configure.ac will appear as a
53 configure and Makefile.in dependency, and will be automatically
56 - The rules for rebuilding Makefiles and Makefile.ins will now
57 rebuild all Makefiles and all Makefile.ins at once when one of
58 configure's dependencies has changed. This is considerably faster
59 than previous implementations, where config.status and automake
60 were run separately in each directory (this still happens when you
61 change a Makefile.am locally, without touching configure.ac or
62 friends). Doing this also solves a longstanding issue: these
63 rebuild rules failed to work when adding new directories to the
64 tree, forcing you to run automake manually.
66 - For similar reasons, the rules to rebuild configure,
67 config.status, and aclocal.m4 are now defined in all directories.
68 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
69 CONFIGURE_DEPENDENCIES (undocumented) variables, you should better
70 define them in all directories. This is easily done using an
71 AC_SUBST (make sure you prefix these dependencies with
72 $(abs_top_srcdir) since this variable will appear at different
73 levels of the build tree).
75 - aclocal will now use `m4_include' instead of copying local m4
76 files into aclocal.m4. (Local m4 files are those you ship with
77 your project, other files will be copied as usual.)
79 Because m4_included files are automatically distributed, it means
80 for most projects there is no point in EXTRA_DISTing the list of
81 m4 files which are used. (You can probably get rid of
82 m4/Makefile.am if you had one.)
84 - aclocal will avoid touching aclocal.m4 when possible, so that
85 Autom4te's cache isn't needlessly invalidated. This behavior can
86 be switched off with the new `--force' option.
88 - aclocal now uses Autoconf's --trace to detect macros which are
89 actually used and will no longer include unused macros simply
90 because they where mentioned. This was often the case for macros
93 - New options no-dist and no-dist-gzip.
95 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
96 py-compile, and ylwrap, now all understand --version and --help.
98 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
99 links as part of the distclean target and including source files in
102 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
103 argument. The latter can be used to override the default behavior
106 - Automake will exit with $? = 63 on version mismatch. (So does
107 Autoconf 2.58) missing knows this, and in this case it will
108 emulate the tools as if they were absent. Because older versions
109 of Automake and Autoconf did not use this exit code, this change
110 will only be useful in projects generated with future versions of
113 - When using AC_CONFIG_FILES with multiple input files, Automake
114 generates the first ".in" input file for which a ".am" exists.
115 (Former versions would try to use only the first input file.)
117 - lisp_DATA is now allowed. If you are using the empty ELCFILES
118 idiom to disable byte-compilation of lisp_LISP files, it is
119 recommended that you switch to using lisp_DATA. Note that
120 this is not strictly equivalent: lisp_DATA will install elisp
121 files even if emacs is not installed, while *_LISP do not
122 install anything unless emacs is found.
124 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
125 available. This selection is achieved through the Makefile
126 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
127 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
128 `$(install_sh) -m 0755 -d'.
132 - Because `mkdir -p' is available on most platforms, and we can use
133 `install-sh -d' when it is not, the use of the mkinstalldirs
134 script is being phased out. `automake --add-missing' no longer
135 installs it, and if you remove mkinstalldirs from your package,
136 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
138 Gettext 1.12.1 still requires mkinstalldirs. Fortunately
139 gettextize and autopoint will install it when needed. Automake
140 will continue to define the $(mkinstalldirs) and to distribute
141 mkinstalldirs when this script is in the source tree.
143 - AM_PROG_CC_STDC is now empty. The content of this macro was
144 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
145 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
146 renaming should be safe, even if you have to support several,
147 versions of Automake, because AC_PROG_CC defines this variable
148 since Autoconf 2.54.)
150 - Some users where using the undocumented ACLOCAL_M4_SOURCES
151 variable to override the aclocal.m4 dependencies computed
152 (inaccurately) by older versions of Automake. Because Automake
153 now tracks configure's m4 dependencies accurately (see m4_include
154 above), the use of ACLOCAL_M4_SOURCES should be considered
155 obsolete and will be flagged as such when running `automake
160 - Defining programs conditionally using Automake conditionals no
161 longer leads to a combinatorial explosion. The following
162 construct used to be troublesome when used with dozens of
177 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
179 - Due to implementation constraints, previous versions of Automake
180 proscribed multiple conditional definitions of some variables
190 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
191 This restriction has been lifted, and these variables now
192 support multiple conditional definitions as do other variables.
194 - Cleanup the definitions of $(distdir) and $(top_distdir).
195 $(top_distdir) now points to the root of the distribution
196 directory created during `make dist', as it did in Automake 1.4,
197 not to the root of the build tree as it did in intervening
198 versions. Furthermore these two variables are now only defined in
199 the top level Makefile, and passed to sub-directories when running
202 - The --no-force option now correctly checks the Makefile.in's
203 dependencies before deciding not to update it.
205 - Do not assume that make files are called Makefile in cleaning rules.
207 - Update .info files in the source tree, not in the build tree. This
208 is what the GNU Coding Standard recommend. Only Automake 1.7.x
209 used to update these files in the build tree (previous versions did
210 it in the source tree too), and it caused several problems, varying
211 from mere annoyance to portability issues.
213 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
214 when --add-missing and --force-missing are used. For backward
215 compatibility --add-missing will continue to install COPYING (in
216 `gnu' strictness) when none of these three files exist, but this
217 use is deprecated: you should better choose a license yourself and
218 install it once for all in your source tree (and in your code
221 - Fix ylwrap so that it does not overwrite header files that haven't
222 changed, as the inline rule already does.
224 - User-defined rules override automake-defined rules for the same
225 targets, even when rules do not have commands. This is not new
226 (and was documented), however some of the automake-generated
227 rules have escaped this principle in former Automake versions.
228 Rules for the following targets are affected by this fix:
230 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
231 info, info-am, install-data-am, install-exec-am, install-info,
232 install-info-am, install-man, installcheck-am, maintainer-clean,
233 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
234 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
236 Practically it means that an attempt to supplement the dependencies
237 of some target, as in
241 will now *silently override* the automake definition of the
242 rule for this target. Running `automake -Woverride' will diagnose
243 all such overriding definitions.
245 It should be noted that almost all these targets support a *-local
246 variant that is meant to supplement the automake-defined rule
247 (See node `Extending' in the manual). The above rule should
250 clean-local: my-clean-rule
252 These *-local targets have been documented since at least
253 Automake 1.2, so you should not fear the change if you have
254 to support multiple automake versions.
258 - The Automake manual is now distributed under the terms of the GNU FDL.
260 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
262 - core dumps are no longer removed by the cleaning rules. There are
263 at least three reasons for this:
264 1. These files should not be created by any build step,
265 so their removal do not fit any of the cleaning rules.
266 Actually, they may be precious to the developer.
267 2. If such file is created during a build, then it's clearly a
268 bug Automake should not hide. Not removing the file will
269 cause `make distcheck' to complain about its presence.
270 3. Operating systems have different naming conventions for
271 core dump files. A core file on one system might be a
272 completely legitimate data file on another system.
274 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
275 defined by Automake. This means that any definition in the
276 environment will be used, unless overridden in the Makefile.am or
277 on the command line. The old behavior, where these variables were
278 defined empty in each Makefile, can be obtained by AC_SUBSTing or
279 AC_ARG_VARing each variable from configure.ac.
282 * Fix install-strip to work with nobase_ binaries.
283 * Fix renaming of #line directives in ylwrap.
284 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
287 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
288 * Fix detection of Debian's install-info, broken since version 1.5.
289 (Debian bug #213524).
290 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
291 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
294 * The implementation of automake's --no-force option is unreliable,
295 so this option is ignored in this version. A real fix will appear in
296 Automake 1.8. (Debian Bug #206299)
297 * AM_PATH_PYTHON: really check the whole list of interpreters if no
298 argument is given. (PR/399)
299 * Do not warn about leading `_' in variable names, even with -Wportability.
300 * Support user redefinitions of TEXINFO_TEX.
301 * depcomp: support AIX Compiler version 6.
302 * Fix missing rebuilds during `make dist' with BSD make.
303 (Could produce tarballs containing out-of-date files.)
304 * Resurrect multilib support.
305 * Noteworthy manual updates:
306 - Extending aclocal: how to write m4 macros that won't trigger warnings
308 - A Shared Library: Rewrite and split into subsections.
311 * Fix depcomp's icc mode for ICC 7.1.
312 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
313 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
314 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
315 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
316 * Remove Latin-1 characters from elisp-comp.
317 * Update the manual's @dircategory to match the Free Software Directory.
320 * Update install-sh's license to remove an advertising clause.
322 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
323 that caused invalid Makefile.ins to be generated.
324 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
325 * New FAQ entry: renamed objects.
328 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
329 the Emacs implementation)
330 * Fix output of aclocal.m4 dependencies in subdirectories.
331 * Use `mv -f' instead of `mv' in fastdep rules.
332 * Upgrade mdate-sh to work on OS/2.
333 * Don't byte-compile elisp files when ELCFILES is set empty.
334 (this documented feature was broken by 1.7.3)
335 * Diagnose trailing backslashes on last line of Makefile.am.
336 * Diagnose whitespace following trailing backslashes.
337 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
338 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
340 * `make install' will build `BUILT_SOURCES' first.
341 * Minor documentation fixes.
344 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
345 * Query distutils for `pythondir' and `pythonexecdir', instead of
346 using an hardcoded path. This should allow builds on 64-bit
347 distributions that usually use lib64/ instead of lib/.
348 * AM_PATH_PYTHON will also search for python2.3.
349 * elisp files are now built all at once instead of one by one. Besides
350 incurring a speed-up, this is required to support interdependent elisp files.
352 - `make distcheck' will now work in `_inst/' and `_build' instead
353 of `=inst/' and `=build/'
354 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
355 - install/uninstall `*.i[0-9][0-9]'-style info files
356 - more changes that affect only the Automake package (not its output)
357 * Fix some incompatibilities with upcoming perl-5.10.
358 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
361 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
362 is troublesome with gcc and Solaris compilers. (PR/385)
363 - makedepend mode: work with Libtool. (PR/385 too)
365 * better support for unusual gettext setups, such as multiple po/ directories
367 - Flag missing po/ and intl/ directories as warnings, not errors.
368 - Disable these warnings if po/ does not exist.
369 * Noteworthy manual updates:
371 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
373 - Document `AM_YFLAGS = -d'. (PR/382)
376 * Fix installation and uninstallation of Info files built in subdirectories.
377 * Do not run `./configure --with-included-gettext' during `make distcheck'
378 if AM_GNU_GETTEXT([external]) is used.
379 * Correctly uninstall renamed man pages.
380 * Do not strip escaped newline in variables defined in one condition
381 and augmented in another condition.
382 * Fix ansi2knr rules for LIBOBJS sources.
383 * Clean all known Texinfo index files, not only those which appear to
384 be used, because we cannot know wich indexes are used in included files.
385 (PR/375, Debian Bug #168671)
386 * Honor only the first @setfilename seen in a Texinfo file.
387 * Treat "required file X not found" diagnostics as errors (exit status 1).
388 * Don't complain that a required file is not found when it is a Makefile
390 * Don't use single suffix inference rules when building `.info'-less
391 Info files, for the sake of Solaris make.
392 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
393 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
394 * Warn about multiple inference rules when -Wportability is used. (PR/372)
395 * Fix building of deansified files from subdirectories. (PR/370)
396 * Add missing `fi' in the .c->.obj rules.
397 * Improve install-sh to work even when names contain spaces or certain
398 (but not all) shell metachars.
399 * Fix the following spurious failures in the test suite:
400 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
401 * Noteworthy manual updates:
402 - Augment the section about BUILT_SOURCES.
403 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
406 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
408 * Aclocal should now recognize macro names containing parentheses, e.g.
409 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
410 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
412 * Install Python files even if they were built. (PR/369)
413 * Have stamp-vti dependent upon configure instead of configure.ac, as the
414 version might not be defined in the latter. (PR/358)
415 * Reorder arguments passed to a couple of commands, so things works
416 when POSIXLY_CORRECT=1.
417 * Fix a regex that can cause Perl to segfault on large input.
419 * Fix distribution of packages that have some sources defined conditionally,
420 as in the `Conditional compilation using Automake conditionals' example
422 * Fix spurious test suite failures on IRIX.
423 * Don't report a required variable as undefined if it has been
424 defined conditionally for the "right" conditions.
425 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
426 `make distcheck' fails.
427 * Fix distribution of included Makefile fragment, so we don't create
428 spurious directories in the distribution. (PR/366)
429 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
432 * Autoconf 2.54 is required.
433 * `aclocal' and `automake' will no longer warn about obsolete
434 configure macros. This is done by `autoconf -Wobsolete'.
435 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
436 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
437 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
438 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
439 `configure.ac' for you.
440 * Support for per-program and per-library `_CPPFLAGS'.
441 * New `ctags' target (builds CTAGS files).
442 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
443 (see `automake --help' or the manual for a list of them).
444 * Honor the WARNINGS environment variable.
445 * Omit the call to depcomp when using gcc3: call the compiler directly.
446 * A new option, std-options, tests that programs support --help and --version
447 when `make installcheck' is run. This is enabled by --gnits.
448 * Texinfo rules now support the `ps' and `pdf' targets.
449 * Info files are now created in the build directory, not the source directory.
450 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
452 * `make distcheck' will enforce DESTDIR support by attempting
454 * `+=' can be used in conditionals, even if the augmented variable
455 was defined for another condition.
456 * Makefile fragments (inserted with `include') are always distributed.
457 * Use Autoconf's --trace interface to inspect configure.ac and get
458 a more accurate view of it.
459 * Add support for extending aclocal's default macro search path
460 using a `dirlist' file within the aclocal directory.
461 * automake --output-dir is deprecated.
462 * The part of the distcheck target that checks whether uninstall actually
463 removes all installed files has been moved in a separate target,
464 distuninstallcheck, so it can be overridden easily.
468 * Support for AM_INIT_GETTEXT([external])
469 * Bug fixes, including:
470 - Fix Automake's own `make install' so it works even if `ln' doesn't.
471 - nobase_ programs and scripts honor --program-transform correctly.
472 - Erase configure.lineno during `make distclean'.
473 - Erase YACC and LEX outputs during `make maintainer-clean'.
476 * Many bug fixes, including:
477 - Requiring the current version works.
478 - Fix "$@" portability issues (for Zsh).
479 - Fix output of dummy dependency files in presence of post-processed
481 - Don't compute dependencies in background to avoid races with libtool.
482 - Fix handling of _OBJECTS variables for targets sharing source variables.
483 - Check dependency mode for Java when AM_PROG_GCJ is used.
486 * automake --output-dir is deprecated
487 * Many bug fixes, including:
488 - Don't choke on AM_LDFLAGS definitions.
489 - Clean libtool objects from subdirectories.
490 - Allow configure variables with reserved suffix and unknown prefix
491 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
492 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
495 * Autoconf 2.52 is required.
496 * automake no longer run libtoolize.
497 This is the job of autoreconf (from GNU Autoconf).
498 * `dist' generates all the archive flavors, as did `dist-all'.
499 * `dist-gzip' generates the Gzip tar file only.
500 * Combining Automake Makefile conditionals no longer lead to a combinatorial
501 explosion. Makefile.in's keep a reasonable size.
502 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
503 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
505 * `#line' of Lex and Yacc files are properly set.
506 * EXTRA_DIST can contain generated directories.
507 * Support for dot-less extensions in suffix rules.
508 * The part of the distcheck target that checks whether distclean actually
509 cleans all built files has been moved in a separate target, distcleancheck,
510 so it can be overridden easily.
511 * `make distcheck' will pass additional options defined in
512 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
513 * Fixed CDPATH portability problems, in particular for MacOS X.
514 * Fixed handling of nobase_ targets.
515 * Fixed support of implicit rules leading to .lo objects.
516 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
517 * Added uninstall-hook target
518 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
519 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
520 (Note that "pkgname" is not "tarname", see the manual for details.)
521 It is also possible to pass a list of global Automake options as
522 first argument to this new form of AM_INIT_AUTOMAKE.
523 * Compiler-based assembler is now called `CCAS'; people expected `AS'
524 to be a real assembler.
525 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
526 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
527 * aclocal and automake are also installed with the version number
528 appended, and some of the install directory names have changed.
529 This lets you have multiple versions installed simultaneously.
530 * Support for parsers and lexers in subdirectories.
533 * Support for `configure.ac'.
534 * Support for `else COND', `endif COND' and negated conditions `!COND'.
535 * `make dist-all' is much faster.
536 * Allows '@' AC_SUBSTs in macro names.
537 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
538 * User-side dependency tracking. Developers no longer need GNU make
540 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
541 * Most files are correctly handled if they appear in subdirs
542 For instance, a _DATA file can appear in a subdir
543 * GNU tar is no longer required for `make dist'
544 * Added support for `dist_' and `nodist_' prefixes
545 * Added support for `nobase_' prefix
546 * Compiled Java support
547 * Support for per-executable and per-library compilation flags
551 * Added support for the Fortran 77 programming language.
552 * Re-indexed the Automake Texinfo manual.
553 * Added `AM_FOOFLAGS' variable for each compiler invocation;
554 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
555 * Support for latest autoconf, including support for objext
556 * Can now put `.' in SUBDIRS to control build order
557 * `include' command and `+=' support for macro assignment
558 * Dependency tracking no long susceptible to deleted header file problem
559 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
564 * Better Cygwin32 support
