3 * Bugs introduced by 1.8:
5 - Fix Config.pm import error with old Perl versions (at least
6 5.005_03). One symptom is that aclocal could not find its macro
9 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
10 created by `make install' are always world readable, even if the
11 installer happens to have an overly restrictive umask (e.g. 077).
12 This was a mistake and has been reverted. There are at least two
13 reasons why we must not use `-m 0755':
14 - it causes special bits like SGID to be ignored,
15 - it may be too restrictive (some setups expect 775 directories).
17 - Honor definitions in m4_included files. aclocal 1.8 had been
18 updated to check m4_included files for new requirements, but
19 forgot that these m4_included files can also provide new
22 This principally affected packages that were m4_including files in
23 a way that aclocal would not have to duplicate entire M4 files
24 into aclocal.m4. Since aclocal 1.8.x will precisely output
25 m4_includes for local M4 files, we recommend that you clean up
26 your setup, removing all manual m4_includes and letting aclocal
29 - Output detailed menus in the Info version if the Automake manual,
30 so that Emacs can locate the indexes.
32 - configure.ac and configure were listed twice in DIST_COMMON (an
33 internal variable where Automake lists configury files to
34 distribute). This was harmless, but unaesthetic.
36 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
37 This was an issue only in the Automake package itself, not in
42 - Fix an unexpected diagnostic occurring when users attempt
43 to override some internal variables that Automake appends to.
45 - aclocal now scans configure.ac for macro definitions (PR/319).
47 - Fix a portability issue with OSF1/Tru64 Make. If a directory
48 distributes files which are outside itself (this usually occurs
49 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
50 from a parent package), then `make distcheck' fails due to an
51 optimization performed by OSF1/Tru64 Make in its VPATH handling.
52 (tests/subpkg2.test failure)
54 - Fix another portability issue with Sun and OSF1/Tru64 Make.
55 In a VPATH-build configuration, `make install' would install
56 nobase_ files to wrong locations.
58 - Fix a Perl `uninitialized value' diagnostic occurring when
59 automake complains that a Texinfo file does not have a
60 @setfilename statement.
62 * Spurious failures in test suite:
64 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
65 tests/ltconv.test: fix failures with CVS Libtool.
66 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
67 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
68 fix failures with old Texinfo versions.
75 - The NEWS file is more verbose.
79 - Autoconf 2.58 or greater is required.
83 - Default source file names in the absence of a _SOURCES declaration
84 are made by removing any target extension before appending `.c', so
85 to make the libtool module `foo.la' from `foo.c', you only need to
88 lib_LTLIBRARIES = foo.la
89 foo_la_LDFLAGS = -module
91 For backward compatibility, foo_la.c will be used instead of
92 foo.c if this file exists or is the explicit target of a rule.
93 However -Wobsolete will warn about this deprecated naming.
95 - AR's `cru' flags are now set in a global ARFLAGS variable instead
96 of being hard-coded in each $(AR) invocation, so they can be
97 substituted from configure.ac. This has been requested by people
98 dealing with non-POSIX ar implementations.
100 - New warning option: -Woverride. This will warn about any user
101 target or variable definitions which override Automake
104 - Texinfo rules back up and restore info files when makeinfo fails.
106 - Texinfo rules now support the `html' target.
107 Running this requires Texinfo 4.0 or greater.
109 `html' is a new recursive target, so if your package mixes
110 hand-crafted `Makefile.in's with Automake-generated
111 `Makefile.in's, you should adjust the former to support (or
112 ignore) this target so that `make html' recurses successfully. If
113 you had a custom `html' rule in your `Makefile.am', it's better to
114 rename it as `html-local', otherwise your rule will override
115 Automake's new rule (you can check that by running `automake
116 -Woverride') and that will stop the recursion to subdirectories.
118 Last but not least, this `html' rule is declared PHONY, even when
119 overridden. Fortunately, it appears that few packages use a
120 non-PHONY `html' rule.
122 - Any file which is m4_included from configure.ac will appear as a
123 configure and Makefile.in dependency, and will be automatically
126 - The rules for rebuilding Makefiles and Makefile.ins will now
127 rebuild all Makefiles and all Makefile.ins at once when one of
128 configure's dependencies has changed. This is considerably faster
129 than previous implementations, where config.status and automake
130 were run separately in each directory (this still happens when you
131 change a Makefile.am locally, without touching configure.ac or
132 friends). Doing this also solves a longstanding issue: these
133 rebuild rules failed to work when adding new directories to the
134 tree, forcing you to run automake manually.
136 - For similar reasons, the rules to rebuild configure,
137 config.status, and aclocal.m4 are now defined in all directories.
138 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
139 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
140 should better define them in all directories. This is easily done
141 using an AC_SUBST (make sure you prefix these dependencies with
142 $(top_srcdir) since this variable will appear at different
143 levels of the build tree).
145 - aclocal will now use `m4_include' instead of copying local m4
146 files into aclocal.m4. (Local m4 files are those you ship with
147 your project, other files will be copied as usual.)
149 Because m4_included files are automatically distributed, it means
150 for most projects there is no point in EXTRA_DISTing the list of
151 m4 files which are used. (You can probably get rid of
152 m4/Makefile.am if you had one.)
154 - aclocal will avoid touching aclocal.m4 when possible, so that
155 Autom4te's cache isn't needlessly invalidated. This behavior can
156 be switched off with the new `--force' option.
158 - aclocal now uses Autoconf's --trace to detect macros which are
159 actually used and will no longer include unused macros simply
160 because they where mentioned. This was often the case for macros
161 called conditionally.
163 - New options no-dist and no-dist-gzip.
165 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
166 py-compile, and ylwrap, now all understand --version and --help.
168 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
169 links as part of the distclean target and including source files in
172 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
173 argument. The latter can be used to override the default behavior
176 - Automake will exit with $? = 63 on version mismatch. (So does
177 Autoconf 2.58) missing knows this, and in this case it will
178 emulate the tools as if they were absent. Because older versions
179 of Automake and Autoconf did not use this exit code, this change
180 will only be useful in projects generated with future versions of
183 - When using AC_CONFIG_FILES with multiple input files, Automake
184 generates the first ".in" input file for which a ".am" exists.
185 (Former versions would try to use only the first input file.)
187 - lisp_DATA is now allowed. If you are using the empty ELCFILES
188 idiom to disable byte-compilation of lisp_LISP files, it is
189 recommended that you switch to using lisp_DATA. Note that
190 this is not strictly equivalent: lisp_DATA will install elisp
191 files even if emacs is not installed, while *_LISP do not
192 install anything unless emacs is found.
194 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
195 available. This selection is achieved through the Makefile
196 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
197 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
198 `$(install_sh) -m 0755 -d'.
202 - Because `mkdir -p' is available on most platforms, and we can use
203 `install-sh -d' when it is not, the use of the mkinstalldirs
204 script is being phased out. `automake --add-missing' no longer
205 installs it, and if you remove mkinstalldirs from your package,
206 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
208 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
209 gettextize and autopoint will install it when needed. Automake
210 will continue to define the $(mkinstalldirs) and to distribute
211 mkinstalldirs when this script is in the source tree.
213 - AM_PROG_CC_STDC is now empty. The content of this macro was
214 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
215 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
216 renaming should be safe, even if you have to support several,
217 versions of Automake, because AC_PROG_CC defines this variable
218 since Autoconf 2.54.)
220 - Some users where using the undocumented ACLOCAL_M4_SOURCES
221 variable to override the aclocal.m4 dependencies computed
222 (inaccurately) by older versions of Automake. Because Automake
223 now tracks configure's m4 dependencies accurately (see m4_include
224 above), the use of ACLOCAL_M4_SOURCES should be considered
225 obsolete and will be flagged as such when running `automake
230 - Defining programs conditionally using Automake conditionals no
231 longer leads to a combinatorial explosion. The following
232 construct used to be troublesome when used with dozens of
247 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
249 - Due to implementation constraints, previous versions of Automake
250 proscribed multiple conditional definitions of some variables
260 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
261 This restriction has been lifted, and these variables now
262 support multiple conditional definitions as do other variables.
264 - Cleanup the definitions of $(distdir) and $(top_distdir).
265 $(top_distdir) now points to the root of the distribution
266 directory created during `make dist', as it did in Automake 1.4,
267 not to the root of the build tree as it did in intervening
268 versions. Furthermore these two variables are now only defined in
269 the top level Makefile, and passed to sub-directories when running
272 - The --no-force option now correctly checks the Makefile.in's
273 dependencies before deciding not to update it.
275 - Do not assume that make files are called Makefile in cleaning rules.
277 - Update .info files in the source tree, not in the build tree. This
278 is what the GNU Coding Standard recommend. Only Automake 1.7.x
279 used to update these files in the build tree (previous versions did
280 it in the source tree too), and it caused several problems, varying
281 from mere annoyance to portability issues.
283 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
284 when --add-missing and --force-missing are used. For backward
285 compatibility --add-missing will continue to install COPYING (in
286 `gnu' strictness) when none of these three files exist, but this
287 use is deprecated: you should better choose a license yourself and
288 install it once for all in your source tree (and in your code
291 - Fix ylwrap so that it does not overwrite header files that haven't
292 changed, as the inline rule already does.
294 - User-defined rules override automake-defined rules for the same
295 targets, even when rules do not have commands. This is not new
296 (and was documented), however some of the automake-generated
297 rules have escaped this principle in former Automake versions.
298 Rules for the following targets are affected by this fix:
300 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
301 info, info-am, install-data-am, install-exec-am, install-info,
302 install-info-am, install-man, installcheck-am, maintainer-clean,
303 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
304 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
306 Practically it means that an attempt to supplement the dependencies
307 of some target, as in
311 will now *silently override* the automake definition of the
312 rule for this target. Running `automake -Woverride' will diagnose
313 all such overriding definitions.
315 It should be noted that almost all these targets support a *-local
316 variant that is meant to supplement the automake-defined rule
317 (See node `Extending' in the manual). The above rule should
320 clean-local: my-clean-rule
322 These *-local targets have been documented since at least
323 Automake 1.2, so you should not fear the change if you have
324 to support multiple automake versions.
328 - The Automake manual is now distributed under the terms of the GNU FDL.
330 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
332 - core dumps are no longer removed by the cleaning rules. There are
333 at least three reasons for this:
334 1. These files should not be created by any build step,
335 so their removal do not fit any of the cleaning rules.
336 Actually, they may be precious to the developer.
337 2. If such file is created during a build, then it's clearly a
338 bug Automake should not hide. Not removing the file will
339 cause `make distcheck' to complain about its presence.
340 3. Operating systems have different naming conventions for
341 core dump files. A core file on one system might be a
342 completely legitimate data file on another system.
344 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
345 defined by Automake. This means that any definition in the
346 environment will be used, unless overridden in the Makefile.am or
347 on the command line. The old behavior, where these variables were
348 defined empty in each Makefile, can be obtained by AC_SUBSTing or
349 AC_ARG_VARing each variable from configure.ac.
351 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
352 documented. (The is not a new feature, these variables have
353 been there since at least Automake 1.4.)
356 * Fix install-strip to work with nobase_ binaries.
357 * Fix renaming of #line directives in ylwrap.
358 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
361 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
362 * Fix detection of Debian's install-info, broken since version 1.5.
363 (Debian bug #213524).
364 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
365 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
368 * The implementation of automake's --no-force option is unreliable,
369 so this option is ignored in this version. A real fix will appear in
370 Automake 1.8. (Debian Bug #206299)
371 * AM_PATH_PYTHON: really check the whole list of interpreters if no
372 argument is given. (PR/399)
373 * Do not warn about leading `_' in variable names, even with -Wportability.
374 * Support user redefinitions of TEXINFO_TEX.
375 * depcomp: support AIX Compiler version 6.
376 * Fix missing rebuilds during `make dist' with BSD make.
377 (Could produce tarballs containing out-of-date files.)
378 * Resurrect multilib support.
379 * Noteworthy manual updates:
380 - Extending aclocal: how to write m4 macros that won't trigger warnings
382 - A Shared Library: Rewrite and split into subsections.
385 * Fix depcomp's icc mode for ICC 7.1.
386 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
387 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
388 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
389 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
390 * Remove Latin-1 characters from elisp-comp.
391 * Update the manual's @dircategory to match the Free Software Directory.
394 * Update install-sh's license to remove an advertising clause.
396 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
397 that caused invalid Makefile.ins to be generated.
398 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
399 * New FAQ entry: renamed objects.
402 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
403 the Emacs implementation)
404 * Fix output of aclocal.m4 dependencies in subdirectories.
405 * Use `mv -f' instead of `mv' in fastdep rules.
406 * Upgrade mdate-sh to work on OS/2.
407 * Don't byte-compile elisp files when ELCFILES is set empty.
408 (this documented feature was broken by 1.7.3)
409 * Diagnose trailing backslashes on last line of Makefile.am.
410 * Diagnose whitespace following trailing backslashes.
411 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
412 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
414 * `make install' will build `BUILT_SOURCES' first.
415 * Minor documentation fixes.
418 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
419 * Query distutils for `pythondir' and `pythonexecdir', instead of
420 using an hardcoded path. This should allow builds on 64-bit
421 distributions that usually use lib64/ instead of lib/.
422 * AM_PATH_PYTHON will also search for python2.3.
423 * elisp files are now built all at once instead of one by one. Besides
424 incurring a speed-up, this is required to support interdependent elisp files.
426 - `make distcheck' will now work in `_inst/' and `_build' instead
427 of `=inst/' and `=build/'
428 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
429 - install/uninstall `*.i[0-9][0-9]'-style info files
430 - more changes that affect only the Automake package (not its output)
431 * Fix some incompatibilities with upcoming perl-5.10.
432 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
435 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
436 is troublesome with gcc and Solaris compilers. (PR/385)
437 - makedepend mode: work with Libtool. (PR/385 too)
439 * better support for unusual gettext setups, such as multiple po/ directories
441 - Flag missing po/ and intl/ directories as warnings, not errors.
442 - Disable these warnings if po/ does not exist.
443 * Noteworthy manual updates:
445 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
447 - Document `AM_YFLAGS = -d'. (PR/382)
450 * Fix installation and uninstallation of Info files built in subdirectories.
451 * Do not run `./configure --with-included-gettext' during `make distcheck'
452 if AM_GNU_GETTEXT([external]) is used.
453 * Correctly uninstall renamed man pages.
454 * Do not strip escaped newline in variables defined in one condition
455 and augmented in another condition.
456 * Fix ansi2knr rules for LIBOBJS sources.
457 * Clean all known Texinfo index files, not only those which appear to
458 be used, because we cannot know wich indexes are used in included files.
459 (PR/375, Debian Bug #168671)
460 * Honor only the first @setfilename seen in a Texinfo file.
461 * Treat "required file X not found" diagnostics as errors (exit status 1).
462 * Don't complain that a required file is not found when it is a Makefile
464 * Don't use single suffix inference rules when building `.info'-less
465 Info files, for the sake of Solaris make.
466 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
467 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
468 * Warn about multiple inference rules when -Wportability is used. (PR/372)
469 * Fix building of deansified files from subdirectories. (PR/370)
470 * Add missing `fi' in the .c->.obj rules.
471 * Improve install-sh to work even when names contain spaces or certain
472 (but not all) shell metachars.
473 * Fix the following spurious failures in the test suite:
474 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
475 * Noteworthy manual updates:
476 - Augment the section about BUILT_SOURCES.
477 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
480 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
482 * Aclocal should now recognize macro names containing parentheses, e.g.
483 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
484 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
486 * Install Python files even if they were built. (PR/369)
487 * Have stamp-vti dependent upon configure instead of configure.ac, as the
488 version might not be defined in the latter. (PR/358)
489 * Reorder arguments passed to a couple of commands, so things works
490 when POSIXLY_CORRECT=1.
491 * Fix a regex that can cause Perl to segfault on large input.
493 * Fix distribution of packages that have some sources defined conditionally,
494 as in the `Conditional compilation using Automake conditionals' example
496 * Fix spurious test suite failures on IRIX.
497 * Don't report a required variable as undefined if it has been
498 defined conditionally for the "right" conditions.
499 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
500 `make distcheck' fails.
501 * Fix distribution of included Makefile fragment, so we don't create
502 spurious directories in the distribution. (PR/366)
503 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
506 * Autoconf 2.54 is required.
507 * `aclocal' and `automake' will no longer warn about obsolete
508 configure macros. This is done by `autoconf -Wobsolete'.
509 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
510 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
511 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
512 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
513 `configure.ac' for you.
514 * Support for per-program and per-library `_CPPFLAGS'.
515 * New `ctags' target (builds CTAGS files).
516 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
517 (see `automake --help' or the manual for a list of them).
518 * Honor the WARNINGS environment variable.
519 * Omit the call to depcomp when using gcc3: call the compiler directly.
520 * A new option, std-options, tests that programs support --help and --version
521 when `make installcheck' is run. This is enabled by --gnits.
522 * Texinfo rules now support the `ps' and `pdf' targets.
523 * Info files are now created in the build directory, not the source directory.
524 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
526 * `make distcheck' will enforce DESTDIR support by attempting
528 * `+=' can be used in conditionals, even if the augmented variable
529 was defined for another condition.
530 * Makefile fragments (inserted with `include') are always distributed.
531 * Use Autoconf's --trace interface to inspect configure.ac and get
532 a more accurate view of it.
533 * Add support for extending aclocal's default macro search path
534 using a `dirlist' file within the aclocal directory.
535 * automake --output-dir is deprecated.
536 * The part of the distcheck target that checks whether uninstall actually
537 removes all installed files has been moved in a separate target,
538 distuninstallcheck, so it can be overridden easily.
542 * Support for AM_INIT_GETTEXT([external])
543 * Bug fixes, including:
544 - Fix Automake's own `make install' so it works even if `ln' doesn't.
545 - nobase_ programs and scripts honor --program-transform correctly.
546 - Erase configure.lineno during `make distclean'.
547 - Erase YACC and LEX outputs during `make maintainer-clean'.
550 * Many bug fixes, including:
551 - Requiring the current version works.
552 - Fix "$@" portability issues (for Zsh).
553 - Fix output of dummy dependency files in presence of post-processed
555 - Don't compute dependencies in background to avoid races with libtool.
556 - Fix handling of _OBJECTS variables for targets sharing source variables.
557 - Check dependency mode for Java when AM_PROG_GCJ is used.
560 * automake --output-dir is deprecated
561 * Many bug fixes, including:
562 - Don't choke on AM_LDFLAGS definitions.
563 - Clean libtool objects from subdirectories.
564 - Allow configure variables with reserved suffix and unknown prefix
565 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
566 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
569 * Autoconf 2.52 is required.
570 * automake no longer run libtoolize.
571 This is the job of autoreconf (from GNU Autoconf).
572 * `dist' generates all the archive flavors, as did `dist-all'.
573 * `dist-gzip' generates the Gzip tar file only.
574 * Combining Automake Makefile conditionals no longer lead to a combinatorial
