3 - Autoconf 2.59a is required.
5 - Perl 5.6 or greater is required.
7 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
9 - The rebuild rules for distributed Yacc and Lex output will avoid
10 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
13 - Preprocessed assembler (*.S) compilation now honnors CPPFLAGS,
14 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
15 tracking, unlike non-preprocessed assembler (*.s).
17 - aclocal now also supports -Wmumble and -Wno-mumble options.
21 * Makefile.in bloat reduction:
23 - Inference rules are used to compile sources in subdirectories when
24 the `subdir-objects' option is used and no per-target flags are
25 used. This should reduce the size of some projects a lot, because
26 Automake used to output an explicit rule for each such object in
29 - Automake no longer outputs three rules (.o, .obj, .lo) for each
30 object that must be built with explicit rules. It just outputs
31 the rules required to build the kind of object considered: either
32 the two .o and .obj rules for usual objects, or the .lo rule for
35 * Change to Libtool support:
37 - Libtool tags are used with libtool versions that support them.
38 (I.e., with Libtool 1.5 or greater.)
40 - Automake is now able to handle setups where a libtool library is
41 conditionally installed in different directories, as in
44 lib_LTLIBRARIES = liba.la
46 pkglib_LTLIBRARIES = liba.la
52 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
53 really evaluated, before it decides to include them in aclocal.m4.
54 This solves nasty problems with conditional redefinitions of
55 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
56 *.m4 files to be included in any project using these macros.
57 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
58 most famous instance of this bug.)
60 - Do not complain about missing conditionally AC_REQUIREd macros
61 that are not actually used. In 1.8.x aclocal would correctly
62 determine which of these macros were really needed (and include
63 only these in the package); unfortunately it would also require
64 all of them to be present in order to run. This created
65 situations were aclocal would not work on a tarball distributing
66 all the macros it uses. For instance running aclocal on a project
67 containing only the subset of the Gettext macros in use by the
68 project did not work, because gettext conditionally requires other
71 * Portability improvements:
73 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
74 tar-pax. The new option filename-length-max=99 helps diagnosing
75 filenames that are too long for tar-v7. (PR/414)
77 - Variables aumented with `+=' are now automatically flattened (i.e.,
78 trailing backslashes removed) and then wrapped around 80 colummns
79 (adding trailing backslashes). In previous versions, a long series
85 would result in a single-line definition of VAR that could possibly
86 exceed the maximum line length of some make implementations.
88 Non-augmented variables are still output as they are defined in
93 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
94 Works the same as the old Fortran 77 implementation; just replace
95 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
96 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
98 - Support for conditional _LISP.
100 - Support for conditional -hook and -local rules (PR/428).
102 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
104 - Automake will not write any Makefile.ins after the first error it
105 encounters. The previous Makefile.ins (if any) will be left in
106 place. (Warnings will not prevent output, but remember they can
107 be turned into errors with -Werror.)
109 - The restriction that SUBDIRS must contain direct children is gone.
112 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
113 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
117 * Long standing bugs:
119 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
120 so that `make distclean' and `make maintainer-clean' can work.
122 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
124 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
126 - Polish diagnostic when no input file is found.
130 * Long standing bugs:
132 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
133 overridden by the user.
135 - Honor PATH_SEPARATOR in various places of the Automake package, for
138 - Adjust dependency tracking mode detection to ICC 8.0's new output.
141 - Fix install-sh so it can install the `mv' binary... using `mv'.
143 - Fix tru64 dependency tracking for libtool objects.
145 - Work around Exuberant Ctags when creating a TAGS files in a directory
146 without files to scan but with subdirectories to include.
148 * Bugs introduced by 1.8:
150 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
151 not defined in the same conditions as the _LDADD that uses it.
153 - Do not warn when JAVAROOT is overridden, this is legitimate.
157 * Long standing bugs:
159 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
160 or any of the other *dir variables contain a space.
162 Please note that Automake does not and cannot support spaces in
163 filenames that are involved during the build. This change affects
164 only installation paths, so that `make install' does not bomb out
165 in packages configured with
166 ./configure --prefix '/c/Program Files'
168 - Fix the depfiles output so it works with GNU sed (<4.1) even when
169 POSIXLY_CORRECT is set.
171 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
172 since Autoconf 2.54, which defines LIBOBJS itself.
174 - Fix a potential (but unlikely) race condition in parallel elisp
175 builds. (Introduced in 1.7.3.)
177 - Do not assume that users override _DEPENDENCIES in all conditions
178 where Automake will try to define them.
180 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
181 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
184 This fix also affects the $(mkdir_p) variable defined since
185 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
186 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
188 - Secure temporary directory creation in `make distcheck'. (PR/413)
190 - Do not generate two build rules for `parser.h' when the
191 parser appears in two different conditionals.
193 - Work around a Solaris 8 /bin/sh bug in the test for dependency
194 checking. Usually ./configure will not pick this shell; so this
195 fix only helps cases where the shell is forced to /bin/sh.
197 * Bugs introduced by 1.8:
199 - In some situations (hand-written `m4_include's), aclocal would
200 call the `File::Spec->rel2abs' method, which was only introduced
201 in Perl 5.6. This new version reestablish support Perl 5.005.
203 It is likely that the next major Automake releases will require at
204 least Perl 5.6. Consider upgrading your development environment
205 if you are still using the five-year-old Perl 5.005.
207 - Automake would sometimes fail to define rules for targets listed
208 in variables defined in multiple conditions. For instance on
214 it would define only the `a.$(OBJEXT): a.c' rule and omit the
215 `b.$(OBJEXT): b.c' rule.
217 * New sections in manual:
219 - Third-Party Makefiles: how to interface third party Makefiles.
220 - Upgrading: upgrading packages to newer Automake versions.
221 - Multiple Outputs: handling tools that produce many outputs.
225 * A (well known) portability bug slipped in the changes made to
226 install-sh in Automake 1.8.1. The broken install-sh would refuse to
227 install anything on Tru64.
229 * Fix install rules for conditionally built python files. (This never
234 * Bugs introduced by 1.8:
236 - Fix Config.pm import error with old Perl versions (at least
237 5.005_03). One symptom is that aclocal could not find its macro
240 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
241 created by `make install' are always world readable, even if the
242 installer happens to have an overly restrictive umask (e.g. 077).
243 This was a mistake and has been reverted. There are at least two
244 reasons why we must not use `-m 0755':
245 - it causes special bits like SGID to be ignored,
246 - it may be too restrictive (some setups expect 775 directories).
248 - Fix aclocal to honor definitions located in files which have been
249 m4_included manually. aclocal 1.8 had been updated to check
250 m4_included files for new requirements, but forgot that these
251 m4_included files can also provide new definitions.
253 Note that if you have such a setup, we recommend you get rid of
254 it. In the past, there was a reason to m4_include files manually:
255 aclocal used to duplicate entire M4 files into aclocal.m4, even
256 files that were distributed. Some packages were therefore
257 m4_including the distributed file directly, and playing some
258 tricks to ensure aclocal would not copy that file to aclocal.m4,
259 in order to limit the amount of duplication. Since aclocal 1.8.x
260 will precisely output m4_includes for local M4 files, we recommend
261 that you clean up your setup, removing all manual m4_includes and
262 letting aclocal output them.
264 - Output detailed menus in the Info version if the Automake manual,
265 so that Emacs can locate the indexes.
267 - configure.ac and configure were listed twice in DIST_COMMON (an
268 internal variable where Automake lists configury files to
269 distribute). This was harmless, but unaesthetic.
271 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
272 This was an issue only in the Automake package itself, not in
275 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
276 DEST:SRC. This was wrong, as some packages do
277 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
280 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
281 argument. This caused two kinds of failures:
282 - Rules installing data in a conditionally defined directory
283 failed when that directory was undefined. In this case no
284 argument was supplied.
285 - `make installdirs' failed, because several directories were
286 passed to $(mkdir_p). This was an issue only on platform
287 were $(mkdir_p) is implemented with `install-sh -d'.
288 $(mkdir_p) as been changed to accept 0 or more arguments, as
291 * Long-standing bugs:
293 - Fix an unexpected diagnostic occurring when users attempt
294 to override some internal variables that Automake appends to.
296 - aclocal now scans configure.ac for macro definitions (PR/319).
298 - Fix a portability issue with OSF1/Tru64 Make. If a directory
299 distributes files which are outside itself (this usually occurs
300 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
301 from a parent package), then `make distcheck' fails due to an
302 optimization performed by OSF1/Tru64 Make in its VPATH handling.
303 (tests/subpkg2.test failure)
305 - Fix another portability issue with Sun and OSF1/Tru64 Make.
306 In a VPATH-build configuration, `make install' would install
307 nobase_ files to wrong locations.
309 - Fix a Perl `uninitialized value' diagnostic occurring when
310 automake complains that a Texinfo file does not have a
311 @setfilename statement.
313 - Erase config.status.lineno during `make distclean'. This file
314 can be created by config.status. Automake already knew about
315 configure.lineno, but forgot config.status.lineno.
317 - Distribute all files, even those which are built and installed
318 conditionally. This change affects files listed in conditionally
319 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
320 as well as those listed in conditionally defined dist_*_DATA,
321 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
323 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
324 doesn't conform to POSIX.
326 - Normalize help strings for configure variables and options added
331 - Check for python2.4 in AM_PATH_PYTHON.
333 * Spurious failures in test suite:
335 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
336 tests/ltconv.test: fix failures with CVS Libtool.
337 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
338 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
339 fix failures with old Texinfo versions.
345 - The NEWS file is more verbose.
349 - Autoconf 2.58 or greater is required.
353 - Default source file names in the absence of a _SOURCES declaration
354 are made by removing any target extension before appending `.c', so
355 to make the libtool module `foo.la' from `foo.c', you only need to
358 lib_LTLIBRARIES = foo.la
359 foo_la_LDFLAGS = -module
361 For backward compatibility, foo_la.c will be used instead of
362 foo.c if this file exists or is the explicit target of a rule.
363 However -Wobsolete will warn about this deprecated naming.
365 - AR's `cru' flags are now set in a global ARFLAGS variable instead
366 of being hard-coded in each $(AR) invocation, so they can be
367 substituted from configure.ac. This has been requested by people
368 dealing with non-POSIX ar implementations.
370 - New warning option: -Woverride. This will warn about any user
371 target or variable definitions which override Automake
374 - Texinfo rules back up and restore info files when makeinfo fails.
376 - Texinfo rules now support the `html' target.
377 Running this requires Texinfo 4.0 or greater.
379 `html' is a new recursive target, so if your package mixes
380 hand-crafted `Makefile.in's with Automake-generated
381 `Makefile.in's, you should adjust the former to support (or
382 ignore) this target so that `make html' recurses successfully. If
383 you had a custom `html' rule in your `Makefile.am', it's better to
384 rename it as `html-local', otherwise your rule will override
385 Automake's new rule (you can check that by running `automake
386 -Woverride') and that will stop the recursion to subdirectories.
388 Last but not least, this `html' rule is declared PHONY, even when
389 overridden. Fortunately, it appears that few packages use a
390 non-PHONY `html' rule.
392 - Any file which is m4_included from configure.ac will appear as a
393 configure and Makefile.in dependency, and will be automatically
396 - The rules for rebuilding Makefiles and Makefile.ins will now
397 rebuild all Makefiles and all Makefile.ins at once when one of
398 configure's dependencies has changed. This is considerably faster
399 than previous implementations, where config.status and automake
400 were run separately in each directory (this still happens when you
401 change a Makefile.am locally, without touching configure.ac or
402 friends). Doing this also solves a longstanding issue: these
403 rebuild rules failed to work when adding new directories to the
404 tree, forcing you to run automake manually.
406 - For similar reasons, the rules to rebuild configure,
407 config.status, and aclocal.m4 are now defined in all directories.
408 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
409 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
410 should better define them in all directories. This is easily done
411 using an AC_SUBST (make sure you prefix these dependencies with
412 $(top_srcdir) since this variable will appear at different
413 levels of the build tree).
415 - aclocal will now use `m4_include' instead of copying local m4
416 files into aclocal.m4. (Local m4 files are those you ship with
417 your project, other files will be copied as usual.)
419 Because m4_included files are automatically distributed, it means
420 for most projects there is no point in EXTRA_DISTing the list of
421 m4 files which are used. (You can probably get rid of
422 m4/Makefile.am if you had one.)
424 - aclocal will avoid touching aclocal.m4 when possible, so that
425 Autom4te's cache isn't needlessly invalidated. This behavior can
426 be switched off with the new `--force' option.
428 - aclocal now uses Autoconf's --trace to detect macros which are
429 actually used and will no longer include unused macros simply
430 because they where mentioned. This was often the case for macros
431 called conditionally.
433 - New options no-dist and no-dist-gzip.
435 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
436 py-compile, and ylwrap, now all understand --version and --help.
438 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
439 links as part of the distclean target and including source files in
442 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
443 argument. The latter can be used to override the default behavior
446 - Automake will exit with $? = 63 on version mismatch. (So does
447 Autoconf 2.58) missing knows this, and in this case it will
448 emulate the tools as if they were absent. Because older versions
449 of Automake and Autoconf did not use this exit code, this change
450 will only be useful in projects generated with future versions of
453 - When using AC_CONFIG_FILES with multiple input files, Automake
454 generates the first ".in" input file for which a ".am" exists.
455 (Former versions would try to use only the first input file.)
457 - lisp_DATA is now allowed. If you are using the empty ELCFILES
458 idiom to disable byte-compilation of lisp_LISP files, it is
459 recommended that you switch to using lisp_DATA. Note that
460 this is not strictly equivalent: lisp_DATA will install elisp
461 files even if emacs is not installed, while *_LISP do not
462 install anything unless emacs is found.
464 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
465 available. This selection is achieved through the Makefile
466 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
467 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
468 `$(install_sh) -m 0755 -d'.
472 - Because `mkdir -p' is available on most platforms, and we can use
473 `install-sh -d' when it is not, the use of the mkinstalldirs
474 script is being phased out. `automake --add-missing' no longer
475 installs it, and if you remove mkinstalldirs from your package,
476 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
478 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
479 gettextize and autopoint will install it when needed. Automake
480 will continue to define the $(mkinstalldirs) and to distribute
481 mkinstalldirs when this script is in the source tree.
483 - AM_PROG_CC_STDC is now empty. The content of this macro was
484 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
485 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
486 renaming should be safe, even if you have to support several,
487 versions of Automake, because AC_PROG_CC defines this variable
488 since Autoconf 2.54.)
490 - Some users where using the undocumented ACLOCAL_M4_SOURCES
491 variable to override the aclocal.m4 dependencies computed
492 (inaccurately) by older versions of Automake. Because Automake
493 now tracks configure's m4 dependencies accurately (see m4_include
494 above), the use of ACLOCAL_M4_SOURCES should be considered
495 obsolete and will be flagged as such when running `automake
500 - Defining programs conditionally using Automake conditionals no
501 longer leads to a combinatorial explosion. The following
502 construct used to be troublesome when used with dozens of
517 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
519 - Due to implementation constraints, previous versions of Automake
520 proscribed multiple conditional definitions of some variables
530 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
531 This restriction has been lifted, and these variables now
532 support multiple conditional definitions as do other variables.
534 - Cleanup the definitions of $(distdir) and $(top_distdir).
535 $(top_distdir) now points to the root of the distribution
536 directory created during `make dist', as it did in Automake 1.4,
537 not to the root of the build tree as it did in intervening
538 versions. Furthermore these two variables are now only defined in
539 the top level Makefile, and passed to sub-directories when running
542 - The --no-force option now correctly checks the Makefile.in's
543 dependencies before deciding not to update it.
545 - Do not assume that make files are called Makefile in cleaning rules.
547 - Update .info files in the source tree, not in the build tree. This
548 is what the GNU Coding Standard recommend. Only Automake 1.7.x
549 used to update these files in the build tree (previous versions did
550 it in the source tree too), and it caused several problems, varying
551 from mere annoyance to portability issues.
553 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
554 when --add-missing and --force-missing are used. For backward
555 compatibility --add-missing will continue to install COPYING (in
556 `gnu' strictness) when none of these three files exist, but this
557 use is deprecated: you should better choose a license yourself and
558 install it once for all in your source tree (and in your code
561 - Fix ylwrap so that it does not overwrite header files that haven't
562 changed, as the inline rule already does.
564 - User-defined rules override automake-defined rules for the same
565 targets, even when rules do not have commands. This is not new
566 (and was documented), however some of the automake-generated
567 rules have escaped this principle in former Automake versions.
568 Rules for the following targets are affected by this fix:
570 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
571 info, info-am, install-data-am, install-exec-am, install-info,
572 install-info-am, install-man, installcheck-am, maintainer-clean,
573 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
574 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
576 Practically it means that an attempt to supplement the dependencies
577 of some target, as in
581 will now *silently override* the automake definition of the
582 rule for this target. Running `automake -Woverride' will diagnose
583 all such overriding definitions.
585 It should be noted that almost all these targets support a *-local
586 variant that is meant to supplement the automake-defined rule
587 (See node `Extending' in the manual). The above rule should
590 clean-local: my-clean-rule
592 These *-local targets have been documented since at least
593 Automake 1.2, so you should not fear the change if you have
594 to support multiple automake versions.
598 - The Automake manual is now distributed under the terms of the GNU FDL.
600 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
602 - core dumps are no longer removed by the cleaning rules. There are
603 at least three reasons for this:
604 1. These files should not be created by any build step,
605 so their removal do not fit any of the cleaning rules.
606 Actually, they may be precious to the developer.
607 2. If such file is created during a build, then it's clearly a
608 bug Automake should not hide. Not removing the file will
609 cause `make distcheck' to complain about its presence.
610 3. Operating systems have different naming conventions for
611 core dump files. A core file on one system might be a
612 completely legitimate data file on another system.
614 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
615 defined by Automake. This means that any definition in the
616 environment will be used, unless overridden in the Makefile.am or
617 on the command line. The old behavior, where these variables were
618 defined empty in each Makefile, can be obtained by AC_SUBSTing or
619 AC_ARG_VARing each variable from configure.ac.
621 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
622 documented. (The is not a new feature, these variables have
623 been there since at least Automake 1.4.)
626 * Fix install-strip to work with nobase_ binaries.
627 * Fix renaming of #line directives in ylwrap.
628 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
631 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
632 * Fix detection of Debian's install-info, broken since version 1.5.
633 (Debian bug #213524).
634 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
635 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
638 * The implementation of automake's --no-force option is unreliable,
639 so this option is ignored in this version. A real fix will appear in
640 Automake 1.8. (Debian Bug #206299)
641 * AM_PATH_PYTHON: really check the whole list of interpreters if no
642 argument is given. (PR/399)
643 * Do not warn about leading `_' in variable names, even with -Wportability.
644 * Support user redefinitions of TEXINFO_TEX.
645 * depcomp: support AIX Compiler version 6.
646 * Fix missing rebuilds during `make dist' with BSD make.
647 (Could produce tarballs containing out-of-date files.)
648 * Resurrect multilib support.
649 * Noteworthy manual updates:
650 - Extending aclocal: how to write m4 macros that won't trigger warnings
652 - A Shared Library: Rewrite and split into subsections.
655 * Fix depcomp's icc mode for ICC 7.1.
656 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
657 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
658 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
659 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
660 * Remove Latin-1 characters from elisp-comp.
661 * Update the manual's @dircategory to match the Free Software Directory.
664 * Update install-sh's license to remove an advertising clause.
666 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
667 that caused invalid Makefile.ins to be generated.
668 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
669 * New FAQ entry: renamed objects.
672 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
673 the Emacs implementation)
674 * Fix output of aclocal.m4 dependencies in subdirectories.
675 * Use `mv -f' instead of `mv' in fastdep rules.
676 * Upgrade mdate-sh to work on OS/2.
677 * Don't byte-compile elisp files when ELCFILES is set empty.
678 (this documented feature was broken by 1.7.3)
679 * Diagnose trailing backslashes on last line of Makefile.am.
680 * Diagnose whitespace following trailing backslashes.
681 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
682 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
684 * `make install' will build `BUILT_SOURCES' first.
685 * Minor documentation fixes.
688 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
689 * Query distutils for `pythondir' and `pythonexecdir', instead of
690 using an hardcoded path. This should allow builds on 64-bit
691 distributions that usually use lib64/ instead of lib/.
692 * AM_PATH_PYTHON will also search for python2.3.
693 * elisp files are now built all at once instead of one by one. Besides
694 incurring a speed-up, this is required to support interdependent elisp files.
696 - `make distcheck' will now work in `_inst/' and `_build' instead
697 of `=inst/' and `=build/'
698 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
699 - install/uninstall `*.i[0-9][0-9]'-style info files

701 * Fix some incompatibilities with upcoming perl-5.10.
702 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
705 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
706 is troublesome with gcc and Solaris compilers. (PR/385)
707 - makedepend mode: work with Libtool. (PR/385 too)
709 * better support for unusual gettext setups, such as multiple po/ directories
711 - Flag missing po/ and intl/ directories as warnings, not errors.
712 - Disable these warnings if po/ does not exist.
713 * Noteworthy manual updates:
715 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
717 - Document `AM_YFLAGS = -d'. (PR/382)
720 * Fix installation and uninstallation of Info files built in subdirectories.
721 * Do not run `./configure --with-included-gettext' during `make distcheck'
722 if AM_GNU_GETTEXT([external]) is used.
723 * Correctly uninstall renamed man pages.
724 * Do not strip escaped newline in variables defined in one condition
725 and augmented in another condition.
726 * Fix ansi2knr rules for LIBOBJS sources.
727 * Clean all known Texinfo index files, not only those which appear to
728 be used, because we cannot know wich indexes are used in included files.
729 (PR/375, Debian Bug #168671)
730 * Honor only the first @setfilename seen in a Texinfo file.
731 * Treat "required file X not found" diagnostics as errors (exit status 1).
732 * Don't complain that a required file is not found when it is a Makefile
734 * Don't use single suffix inference rules when building `.info'-less
735 Info files, for the sake of Solaris make.
736 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
737 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
738 * Warn about multiple inference rules when -Wportability is used. (PR/372)
739 * Fix building of deansified files from subdirectories. (PR/370)
740 * Add missing `fi' in the .c->.obj rules.
741 * Improve install-sh to work even when names contain spaces or certain
742 (but not all) shell metachars.
743 * Fix the following spurious failures in the test suite:
744 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
745 * Noteworthy manual updates:
746 - Augment the section about BUILT_SOURCES.
747 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
750 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
752 * Aclocal should now recognize macro names containing parentheses, e.g.
753 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
754 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
756 * Install Python files even if they were built. (PR/369)
757 * Have stamp-vti dependent upon configure instead of configure.ac, as the
758 version might not be defined in the latter. (PR/358)
759 * Reorder arguments passed to a couple of commands, so things works
760 when POSIXLY_CORRECT=1.
761 * Fix a regex that can cause Perl to segfault on large input.
763 * Fix distribution of packages that have some sources defined conditionally,
764 as in the `Conditional compilation using Automake conditionals' example
766 * Fix spurious test suite failures on IRIX.
767 * Don't report a required variable as undefined if it has been
768 defined conditionally for the "right" conditions.
769 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
770 `make distcheck' fails.
771 * Fix distribution of included Makefile fragment, so we don't create
772 spurious directories in the distribution. (PR/366)
773 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
776 * Autoconf 2.54 is required.
777 * `aclocal' and `automake' will no longer warn about obsolete
778 configure macros. This is done by `autoconf -Wobsolete'.
779 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
780 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
781 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
782 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
783 `configure.ac' for you.
784 * Support for per-program and per-library `_CPPFLAGS'.
785 * New `ctags' target (builds CTAGS files).
786 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
787 (see `automake --help' or the manual for a list of them).
788 * Honor the WARNINGS environment variable.
789 * Omit the call to depcomp when using gcc3: call the compiler directly.
790 * A new option, std-options, tests that programs support --help and --version
791 when `make installcheck' is run. This is enabled by --gnits.
792 * Texinfo rules now support the `ps' and `pdf' targets.
793 * Info files are now created in the build directory, not the source directory.
794 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
796 * `make distcheck' will enforce DESTDIR support by attempting
798 * `+=' can be used in conditionals, even if the augmented variable
799 was defined for another condition.
800 * Makefile fragments (inserted with `include') are always distributed.
801 * Use Autoconf's --trace interface to inspect configure.ac and get
802 a more accurate view of it.
803 * Add support for extending aclocal's default macro search path
804 using a `dirlist' file within the aclocal directory.
805 * automake --output-dir is deprecated.
806 * The part of the distcheck target that checks whether uninstall actually
807 removes all installed files has been moved in a separate target,
808 distuninstallcheck, so it can be overridden easily.
812 * Support for AM_INIT_GETTEXT([external])
813 * Bug fixes, including:
814 - Fix Automake's own `make install' so it works even if `ln' doesn't.
815 - nobase_ programs and scripts honor --program-transform correctly.
816 - Erase configure.lineno during `make distclean'.
817 - Erase YACC and LEX outputs during `make maintainer-clean'.
820 * Many bug fixes, including:
821 - Requiring the current version works.
822 - Fix "$@" portability issues (for Zsh).
823 - Fix output of dummy dependency files in presence of post-processed
825 - Don't compute dependencies in background to avoid races with libtool.

827 - Check dependency mode for Java when AM_PROG_GCJ is used.
830 * automake --output-dir is deprecated
831 * Many bug fixes, including:
832 - Don't choke on AM_LDFLAGS definitions.
833 - Clean libtool objects from subdirectories.
834 - Allow configure variables with reserved suffix and unknown prefix
835 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
836 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
839 * Autoconf 2.52 is required.
840 * automake no longer run libtoolize.
841 This is the job of autoreconf (from GNU Autoconf).
842 * `dist' generates all the archive flavors, as did `dist-all'.
843 * `dist-gzip' generates the Gzip tar file only.
844 * Combining Automake Makefile conditionals no longer lead to a combinatorial
845 explosion. Makefile.in's keep a reasonable size.
846 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
847 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
849 * `#line' of Lex and Yacc files are properly set.
850 * EXTRA_DIST can contain generated directories.
851 * Support for dot-less extensions in suffix rules.
852 * The part of the distcheck target that checks whether distclean actually
853 cleans all built files has been moved in a separate target, distcleancheck,
854 so it can be overridden easily.
855 * `make distcheck' will pass additional options defined in
856 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
857 * Fixed CDPATH portability problems, in particular for MacOS X.
858 * Fixed handling of nobase_ targets.
859 * Fixed support of implicit rules leading to .lo objects.
860 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
861 * Added uninstall-hook target
862 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
863 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
864 (Note that "pkgname" is not "tarname", see the manual for details.)
865 It is also possible to pass a list of global Automake options as
866 first argument to this new form of AM_INIT_AUTOMAKE.
867 * Compiler-based assembler is now called `CCAS'; people expected `AS'
868 to be a real assembler.
869 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
870 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
871 * aclocal and automake are also installed with the version number
872 appended, and some of the install directory names have changed.
873 This lets you have multiple versions installed simultaneously.
