3 * Version requirements:
5 - Autoconf 2.62 or greater is required.
9 - The autoconf version check implemented by aclocal in aclocal.m4
10 (and new in Automake 1.10) is degraded to a warning. This helps
11 in the common case where the Autoconf versions used are compatible.
13 * Change to Libtool support:
15 - Libtool generic flags are now passed to the install and uninstall
20 - subdir-object mode works now with Fortran (F77, FC, preprocessed
23 - For files with extension .f90, .f95, .f03, or .f08, the flag
24 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
26 - Files with extension .sx are also treated as preprocessed assembler.
28 * Miscellaneous changes:
30 - Automake development is done in a git repository on Savannah now, see
32 http://git.sv.gnu.org/gitweb/?p=automake.git
34 A read-only CVS mirror is provided at
36 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
37 checkout -d automake HEAD
39 - "make dist" can now create lzma-compressed tarballs.
41 - Automake is licensed under GPLv3+. `automake --add-missing' will
42 by default install the GPLv3 file as COPYING if it is missing.
43 Note that Automake will never overwrite an existing COPYING file,
44 even when the `--force-missing' option is used.
46 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
48 - install-sh supports -C, which does not update the installed file
49 (and its time stamps) if the contents did not change.
51 - `make install' now installs multiple files in one `install' invocation
52 for files with DATA, HEADERS, PYTHON, LIBRARIES and TEXINFOS primaries.
54 - The "deleted header file problem" for *.m4 files is avoided by
55 stub rules. This allows `make' to trigger a rerun of `aclocal'
56 also if some previously needed macro file has been removed.
58 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
59 an otherwise up to date tree.
61 - The `color-tests' option causes colored test result output on terminals.
63 - New prefix `notrans_' for manpages which should not be transformed
64 by --program-transform.
66 - New macro AM_COND_IF for conditional evaluation and conditional
69 - For AC_CONFIG_LINKS, if source and destination are equal, do not
70 remove the file in a non-VPATH build. Such setups work with Autoconf
73 - AM_MAINTAINER_MODE now allows for an optional argument specifying
80 - Fix aix dependency tracking for libtool objects.
82 * Bugs introduced by 1.10:
84 - Fix output of dummy dependency files in presence of post-processed
85 Makefile.in's again, but also cope with long lines.
87 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
88 that have been declared as programs in the same Makefile.
89 This is for consistency with the analogous change to TESTS in 1.10.
91 - Fix order of standard includes to again be `-I. -I$(srcdir)',
92 followed by directories containing config headers.
96 * Version requirements:
98 - Autoconf 2.60 or greater is required.
100 - Perl 5.6 or greater is required.
102 * Changes to aclocal:
104 - aclocal now also supports -Wmumble and -Wno-mumble options.
106 - `dirlist' entries (for the aclocal search path) may use shell
107 wildcards such as `*', `?', or `[...]'.
109 - aclocal supports an --install option that will cause system-wide
110 third-party macros to be installed in the local directory
111 specified with the first -I flag. This option also uses #serial
112 lines in M4 files to upgrade local macros.
114 The new aclocal options --dry-run and --diff help to review changes
115 before they are installed.
117 - aclocal now outputs an autoconf version check in aclocal.m4 in
118 projects using automake.
120 For a few years, automake and aclocal have been calling autoconf
121 (or its underlying engine autom4te) to accurately retrieve the
122 data they need from configure.ac and its siblings. Doing so can
123 only work if all autotools use the same version of autoconf. For
124 instance a Makefile.in generated by automake for one version of
125 autoconf may stop working if configure is regenerated with another
126 version of autoconf, and vice versa.
128 This new version check ensures that the whole build system has
129 been generated using the same autoconf version.
131 * Support for new Autoconf macros:
133 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
135 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
136 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
137 in different directories. However, only one instance of such a
138 library objects directory is supported.
140 * Change to Libtool support:
142 - Libtool generic flags (those that go before the --mode=MODE option)
143 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
145 * Yacc and Lex changes:
147 - The rebuild rules for distributed Yacc and Lex output will avoid
148 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
151 - ylwrap is now always used for lex and yacc source files,
152 regardless of whether there is more than one source per directory.
156 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
157 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
158 tracking, unlike non-preprocessed assembler (*.s).
160 - subdir-object mode works now with Assembler. Automake assumes
161 that the compiler understands `-c -o'.
163 - Preprocessed assembler (*.S) compilation now also honors
164 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
166 - Improved support for Objective C:
167 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
168 - A new section of the manual documents the support.
170 - New support for Unified Parallel C:
171 - AM_PROG_UPC looks for a UPC compiler.
172 - A new section of the manual documents the support.
174 - Per-target flags are now correctly handled in link rules.
176 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
177 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
178 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
179 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
181 The fix for compiler flags (i.e., using maude_CFLAGS instead of
182 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
183 is expected to work (and actually works during compilation).
185 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
186 "in addition to" breaks backward compatibility with older versions.
187 If your package used both variables, as in
189 AM_LDFLAGS = common flags
191 a_LDFLAGS = more flags
194 and assumed *_LDFLAGS would sum up, you should rewrite it as
196 AM_LDFLAGS = common flags
198 a_LDFLAGS = $(AM_LDFLAGS) more flags
201 This new behavior of *_LDFLAGS is more coherent with other
202 per-target variables, and the way *_LDFLAGS variables were
203 considered internally.
205 * New installation targets:
207 - New targets mandated by GNU Coding Standards:
212 By default they will only install Texinfo manuals.
213 You can customize them with *-local variants:
219 - The undocumented recursive target `uninstall-info' no longer exists.
220 (`uninstall' is in charge of removing all possible documentation
221 flavors, including optional formats such as dvi, ps, or info even
222 when `no-installinfo' is used.)
224 * Miscellaneous changes:
226 - Automake no longer complains if input files for AC_CONFIG_FILES
227 are specified using shell variables.
229 - clean, distribution, or rebuild rules are normally disabled for
230 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
231 AC_CONFIG_LINK specified using shell variables. However, if these
232 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
233 be able to output rules anyway.
234 (See the Automake documentation for AC_CONFIG_FILES.)
236 - $(EXEEXT) is automatically appended to filenames of TESTS
237 that have been declared as programs in the same Makefile.
238 This is mostly useful when some check_PROGRAMS are listed in TESTS.
240 - `-Wportability' has finally been turned on by default for `gnu' and
241 `gnits' strictness. This means, automake will complain about %-rules
242 or $(GNU Make functions) unless you switch to `foreign' strictness or
243 use `-Wno-portability'.
245 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
246 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
247 $(mkdir_p) variable is still defined (to the same value as
248 $(MKDIR_P)) but should be considered obsolete. If you are using
249 $(mkdir_p) in some of your rules, please plan to update them to
250 $(MKDIR_P) at some point.
252 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
253 They still work in this release, but may be withdrawn in a future one.
255 - Inline compilation rules for gcc3-style dependency tracking are
258 - Automake installs a "Hello World!" example package in $(docdir).
259 This example is used throughout the new "Autotools Introduction"
260 chapter of the manual.
264 * Makefile.in bloat reduction:
266 - Inference rules are used to compile sources in subdirectories when
267 the `subdir-objects' option is used and no per-target flags are
268 used. This should reduce the size of some projects a lot, because
269 Automake used to output an explicit rule for each such object in
272 - Automake no longer outputs three rules (.o, .obj, .lo) for each
273 object that must be built with explicit rules. It just outputs
274 the rules required to build the kind of object considered: either
275 the two .o and .obj rules for usual objects, or the .lo rule for
278 * Change to Libtool support:
280 - Libtool tags are used with libtool versions that support them.
281 (I.e., with Libtool 1.5 or greater.)
283 - Automake is now able to handle setups where a libtool library is
284 conditionally installed in different directories, as in
287 lib_LTLIBRARIES = liba.la
289 pkglib_LTLIBRARIES = liba.la
291 liba_la_SOURCES = ...
293 * Changes to aclocal:
295 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
296 really evaluated, before it decides to include them in aclocal.m4.
297 This solves nasty problems with conditional redefinitions of
298 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
299 *.m4 files to be included in any project using these macros.
300 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
301 most famous instance of this bug.)
303 - Do not complain about missing conditionally AC_REQUIREd macros
304 that are not actually used. In 1.8.x aclocal would correctly
305 determine which of these macros were really needed (and include
306 only these in the package); unfortunately it would also require
307 all of them to be present in order to run. This created
308 situations were aclocal would not work on a tarball distributing
309 all the macros it uses. For instance running aclocal on a project
310 containing only the subset of the Gettext macros in use by the
311 project did not work, because gettext conditionally requires other
314 * Portability improvements:
316 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
317 tar-pax. The new option filename-length-max=99 helps diagnosing
318 filenames that are too long for tar-v7. (PR/414)
320 - Variables aumented with `+=' are now automatically flattened (i.e.,
321 trailing backslashes removed) and then wrapped around 80 colummns
322 (adding trailing backslashes). In previous versions, a long series
328 would result in a single-line definition of VAR that could possibly
329 exceed the maximum line length of some make implementations.
331 Non-augmented variables are still output as they are defined in
336 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
337 Works the same as the old Fortran 77 implementation; just replace
338 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
339 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
341 - Support for conditional _LISP.
343 - Support for conditional -hook and -local rules (PR/428).
345 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
347 - Automake will not write any Makefile.ins after the first error it
348 encounters. The previous Makefile.ins (if any) will be left in
349 place. (Warnings will not prevent output, but remember they can
350 be turned into errors with -Werror.)
352 - The restriction that SUBDIRS must contain direct children is gone.
355 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
356 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
360 * Long standing bugs:
362 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
363 so that `make distclean' and `make maintainer-clean' can work.
365 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
367 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
369 - Polish diagnostic when no input file is found.
373 * Long standing bugs:
375 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
376 overridden by the user.
378 - Honor PATH_SEPARATOR in various places of the Automake package, for
381 - Adjust dependency tracking mode detection to ICC 8.0's new output.
384 - Fix install-sh so it can install the `mv' binary... using `mv'.
386 - Fix tru64 dependency tracking for libtool objects.
388 - Work around Exuberant Ctags when creating a TAGS files in a directory
389 without files to scan but with subdirectories to include.
391 * Bugs introduced by 1.8:
393 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
394 not defined in the same conditions as the _LDADD that uses it.
396 - Do not warn when JAVAROOT is overridden, this is legitimate.
400 * Long standing bugs:
402 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
403 or any of the other *dir variables contain a space.
405 Please note that Automake does not and cannot support spaces in
406 filenames that are involved during the build. This change affects
407 only installation paths, so that `make install' does not bomb out
408 in packages configured with
409 ./configure --prefix '/c/Program Files'
411 - Fix the depfiles output so it works with GNU sed (<4.1) even when
412 POSIXLY_CORRECT is set.
414 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
415 since Autoconf 2.54, which defines LIBOBJS itself.
417 - Fix a potential (but unlikely) race condition in parallel elisp
418 builds. (Introduced in 1.7.3.)
420 - Do not assume that users override _DEPENDENCIES in all conditions
421 where Automake will try to define them.
423 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
424 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
427 This fix also affects the $(mkdir_p) variable defined since
428 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
429 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
431 - Secure temporary directory creation in `make distcheck'. (PR/413)
433 - Do not generate two build rules for `parser.h' when the
434 parser appears in two different conditionals.
436 - Work around a Solaris 8 /bin/sh bug in the test for dependency
437 checking. Usually ./configure will not pick this shell; so this
438 fix only helps cases where the shell is forced to /bin/sh.
440 * Bugs introduced by 1.8:
442 - In some situations (hand-written `m4_include's), aclocal would
443 call the `File::Spec->rel2abs' method, which was only introduced
444 in Perl 5.6. This new version reestablish support Perl 5.005.
446 It is likely that the next major Automake releases will require at
447 least Perl 5.6. Consider upgrading your development environment
448 if you are still using the five-year-old Perl 5.005.
450 - Automake would sometimes fail to define rules for targets listed
451 in variables defined in multiple conditions. For instance on
457 it would define only the `a.$(OBJEXT): a.c' rule and omit the
458 `b.$(OBJEXT): b.c' rule.
460 * New sections in manual:
462 - Third-Party Makefiles: how to interface third party Makefiles.
463 - Upgrading: upgrading packages to newer Automake versions.
464 - Multiple Outputs: handling tools that produce many outputs.
468 * A (well known) portability bug slipped in the changes made to
469 install-sh in Automake 1.8.1. The broken install-sh would refuse to
470 install anything on Tru64.
472 * Fix install rules for conditionally built python files. (This never
477 * Bugs introduced by 1.8:
479 - Fix Config.pm import error with old Perl versions (at least
480 5.005_03). One symptom is that aclocal could not find its macro
483 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
484 created by `make install' are always world readable, even if the
485 installer happens to have an overly restrictive umask (e.g. 077).
486 This was a mistake and has been reverted. There are at least two
487 reasons why we must not use `-m 0755':
488 - it causes special bits like SGID to be ignored,
489 - it may be too restrictive (some setups expect 775 directories).
491 - Fix aclocal to honor definitions located in files which have been
492 m4_included manually. aclocal 1.8 had been updated to check
493 m4_included files for new requirements, but forgot that these
494 m4_included files can also provide new definitions.
496 Note that if you have such a setup, we recommend you get rid of
497 it. In the past, there was a reason to m4_include files manually:
498 aclocal used to duplicate entire M4 files into aclocal.m4, even
499 files that were distributed. Some packages were therefore
500 m4_including the distributed file directly, and playing some
501 tricks to ensure aclocal would not copy that file to aclocal.m4,
502 in order to limit the amount of duplication. Since aclocal 1.8.x
503 will precisely output m4_includes for local M4 files, we recommend
504 that you clean up your setup, removing all manual m4_includes and
505 letting aclocal output them.
507 - Output detailed menus in the Info version if the Automake manual,
508 so that Emacs can locate the indexes.
510 - configure.ac and configure were listed twice in DIST_COMMON (an
511 internal variable where Automake lists configury files to
512 distribute). This was harmless, but unaesthetic.
514 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
515 This was an issue only in the Automake package itself, not in
518 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
519 DEST:SRC. This was wrong, as some packages do
520 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
523 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
524 argument. This caused two kinds of failures:
525 - Rules installing data in a conditionally defined directory
526 failed when that directory was undefined. In this case no
527 argument was supplied.
528 - `make installdirs' failed, because several directories were
529 passed to $(mkdir_p). This was an issue only on platform
530 were $(mkdir_p) is implemented with `install-sh -d'.
531 $(mkdir_p) as been changed to accept 0 or more arguments, as
534 * Long-standing bugs:
536 - Fix an unexpected diagnostic occurring when users attempt
537 to override some internal variables that Automake appends to.
539 - aclocal now scans configure.ac for macro definitions (PR/319).
541 - Fix a portability issue with OSF1/Tru64 Make. If a directory
542 distributes files which are outside itself (this usually occurs
543 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
544 from a parent package), then `make distcheck' fails due to an
545 optimization performed by OSF1/Tru64 Make in its VPATH handling.
546 (tests/subpkg2.test failure)
548 - Fix another portability issue with Sun and OSF1/Tru64 Make.
549 In a VPATH-build configuration, `make install' would install
550 nobase_ files to wrong locations.
552 - Fix a Perl `uninitialized value' diagnostic occurring when
553 automake complains that a Texinfo file does not have a
554 @setfilename statement.
556 - Erase config.status.lineno during `make distclean'. This file
557 can be created by config.status. Automake already knew about
558 configure.lineno, but forgot config.status.lineno.
560 - Distribute all files, even those which are built and installed
561 conditionally. This change affects files listed in conditionally
562 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
563 as well as those listed in conditionally defined dist_*_DATA,
564 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
566 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
567 doesn't conform to POSIX.
569 - Normalize help strings for configure variables and options added
574 - Check for python2.4 in AM_PATH_PYTHON.
576 * Spurious failures in test suite:
578 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
579 tests/ltconv.test: fix failures with CVS Libtool.
580 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
581 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
582 fix failures with old Texinfo versions.
588 - The NEWS file is more verbose.
592 - Autoconf 2.58 or greater is required.
596 - Default source file names in the absence of a _SOURCES declaration
597 are made by removing any target extension before appending `.c', so
598 to make the libtool module `foo.la' from `foo.c', you only need to
601 lib_LTLIBRARIES = foo.la
602 foo_la_LDFLAGS = -module
604 For backward compatibility, foo_la.c will be used instead of
605 foo.c if this file exists or is the explicit target of a rule.
606 However -Wobsolete will warn about this deprecated naming.
608 - AR's `cru' flags are now set in a global ARFLAGS variable instead
609 of being hard-coded in each $(AR) invocation, so they can be
610 substituted from configure.ac. This has been requested by people
611 dealing with non-POSIX ar implementations.
613 - New warning option: -Woverride. This will warn about any user
614 target or variable definitions which override Automake
617 - Texinfo rules back up and restore info files when makeinfo fails.
619 - Texinfo rules now support the `html' target.
620 Running this requires Texinfo 4.0 or greater.
622 `html' is a new recursive target, so if your package mixes
623 hand-crafted `Makefile.in's with Automake-generated
624 `Makefile.in's, you should adjust the former to support (or
625 ignore) this target so that `make html' recurses successfully. If
626 you had a custom `html' rule in your `Makefile.am', it's better to
627 rename it as `html-local', otherwise your rule will override
628 Automake's new rule (you can check that by running `automake
629 -Woverride') and that will stop the recursion to subdirectories.
631 Last but not least, this `html' rule is declared PHONY, even when
632 overridden. Fortunately, it appears that few packages use a
633 non-PHONY `html' rule.
635 - Any file which is m4_included from configure.ac will appear as a
636 configure and Makefile.in dependency, and will be automatically
639 - The rules for rebuilding Makefiles and Makefile.ins will now
640 rebuild all Makefiles and all Makefile.ins at once when one of
641 configure's dependencies has changed. This is considerably faster
642 than previous implementations, where config.status and automake
643 were run separately in each directory (this still happens when you
644 change a Makefile.am locally, without touching configure.ac or
645 friends). Doing this also solves a longstanding issue: these
646 rebuild rules failed to work when adding new directories to the
647 tree, forcing you to run automake manually.
649 - For similar reasons, the rules to rebuild configure,
650 config.status, and aclocal.m4 are now defined in all directories.
651 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
652 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
653 should better define them in all directories. This is easily done
654 using an AC_SUBST (make sure you prefix these dependencies with
655 $(top_srcdir) since this variable will appear at different
656 levels of the build tree).
658 - aclocal will now use `m4_include' instead of copying local m4
659 files into aclocal.m4. (Local m4 files are those you ship with
660 your project, other files will be copied as usual.)
662 Because m4_included files are automatically distributed, it means
663 for most projects there is no point in EXTRA_DISTing the list of
664 m4 files which are used. (You can probably get rid of
665 m4/Makefile.am if you had one.)
667 - aclocal will avoid touching aclocal.m4 when possible, so that
668 Autom4te's cache isn't needlessly invalidated. This behavior can
669 be switched off with the new `--force' option.
671 - aclocal now uses Autoconf's --trace to detect macros which are
672 actually used and will no longer include unused macros simply
673 because they where mentioned. This was often the case for macros
674 called conditionally.
676 - New options no-dist and no-dist-gzip.
678 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
679 py-compile, and ylwrap, now all understand --version and --help.
681 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
682 links as part of the distclean target and including source files in
685 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
686 argument. The latter can be used to override the default behavior
689 - Automake will exit with $? = 63 on version mismatch. (So does
690 Autoconf 2.58) missing knows this, and in this case it will
691 emulate the tools as if they were absent. Because older versions
692 of Automake and Autoconf did not use this exit code, this change
693 will only be useful in projects generated with future versions of
696 - When using AC_CONFIG_FILES with multiple input files, Automake
697 generates the first ".in" input file for which a ".am" exists.
698 (Former versions would try to use only the first input file.)
700 - lisp_DATA is now allowed. If you are using the empty ELCFILES
701 idiom to disable byte-compilation of lisp_LISP files, it is
702 recommended that you switch to using lisp_DATA. Note that
703 this is not strictly equivalent: lisp_DATA will install elisp
704 files even if emacs is not installed, while *_LISP do not
705 install anything unless emacs is found.
707 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
708 available. This selection is achieved through the Makefile
709 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
710 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
711 `$(install_sh) -m 0755 -d'.
715 - Because `mkdir -p' is available on most platforms, and we can use
716 `install-sh -d' when it is not, the use of the mkinstalldirs
717 script is being phased out. `automake --add-missing' no longer
718 installs it, and if you remove mkinstalldirs from your package,
719 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
721 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
722 gettextize and autopoint will install it when needed. Automake
723 will continue to define the $(mkinstalldirs) and to distribute
724 mkinstalldirs when this script is in the source tree.
726 - AM_PROG_CC_STDC is now empty. The content of this macro was
727 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
728 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
729 renaming should be safe, even if you have to support several,
730 versions of Automake, because AC_PROG_CC defines this variable
731 since Autoconf 2.54.)
733 - Some users where using the undocumented ACLOCAL_M4_SOURCES
734 variable to override the aclocal.m4 dependencies computed
735 (inaccurately) by older versions of Automake. Because Automake
736 now tracks configure's m4 dependencies accurately (see m4_include
737 above), the use of ACLOCAL_M4_SOURCES should be considered
738 obsolete and will be flagged as such when running `automake
743 - Defining programs conditionally using Automake conditionals no
744 longer leads to a combinatorial explosion. The following
745 construct used to be troublesome when used with dozens of
760 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
762 - Due to implementation constraints, previous versions of Automake
763 proscribed multiple conditional definitions of some variables
773 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
774 This restriction has been lifted, and these variables now
775 support multiple conditional definitions as do other variables.
777 - Cleanup the definitions of $(distdir) and $(top_distdir).
778 $(top_distdir) now points to the root of the distribution
779 directory created during `make dist', as it did in Automake 1.4,
780 not to the root of the build tree as it did in intervening
781 versions. Furthermore these two variables are now only defined in
782 the top level Makefile, and passed to sub-directories when running
785 - The --no-force option now correctly checks the Makefile.in's
786 dependencies before deciding not to update it.
788 - Do not assume that make files are called Makefile in cleaning rules.
790 - Update .info files in the source tree, not in the build tree. This
791 is what the GNU Coding Standard recommend. Only Automake 1.7.x
792 used to update these files in the build tree (previous versions did
793 it in the source tree too), and it caused several problems, varying
794 from mere annoyance to portability issues.
796 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
797 when --add-missing and --force-missing are used. For backward
798 compatibility --add-missing will continue to install COPYING (in
799 `gnu' strictness) when none of these three files exist, but this
800 use is deprecated: you should better choose a license yourself and
801 install it once for all in your source tree (and in your code
804 - Fix ylwrap so that it does not overwrite header files that haven't
805 changed, as the inline rule already does.
807 - User-defined rules override automake-defined rules for the same
808 targets, even when rules do not have commands. This is not new
809 (and was documented), however some of the automake-generated
810 rules have escaped this principle in former Automake versions.
811 Rules for the following targets are affected by this fix:
813 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
814 info, info-am, install-data-am, install-exec-am, install-info,
815 install-info-am, install-man, installcheck-am, maintainer-clean,
816 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
817 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
819 Practically it means that an attempt to supplement the dependencies
820 of some target, as in
824 will now *silently override* the automake definition of the
825 rule for this target. Running `automake -Woverride' will diagnose
826 all such overriding definitions.
828 It should be noted that almost all these targets support a *-local
829 variant that is meant to supplement the automake-defined rule
830 (See node `Extending' in the manual). The above rule should
833 clean-local: my-clean-rule
835 These *-local targets have been documented since at least
836 Automake 1.2, so you should not fear the change if you have
837 to support multiple automake versions.
841 - The Automake manual is now distributed under the terms of the GNU FDL.
843 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
845 - core dumps are no longer removed by the cleaning rules. There are
846 at least three reasons for this:
847 1. These files should not be created by any build step,
848 so their removal do not fit any of the cleaning rules.
849 Actually, they may be precious to the developer.
850 2. If such file is created during a build, then it's clearly a
851 bug Automake should not hide. Not removing the file will
852 cause `make distcheck' to complain about its presence.
853 3. Operating systems have different naming conventions for
854 core dump files. A core file on one system might be a
855 completely legitimate data file on another system.
857 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
858 defined by Automake. This means that any definition in the
859 environment will be used, unless overridden in the Makefile.am or
860 on the command line. The old behavior, where these variables were
861 defined empty in each Makefile, can be obtained by AC_SUBSTing or
862 AC_ARG_VARing each variable from configure.ac.
864 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
865 documented. (The is not a new feature, these variables have
866 been there since at least Automake 1.4.)
869 * Fix install-strip to work with nobase_ binaries.
870 * Fix renaming of #line directives in ylwrap.
871 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
874 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
875 * Fix detection of Debian's install-info, broken since version 1.5.
876 (Debian bug #213524).
877 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
878 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
881 * The implementation of automake's --no-force option is unreliable,
882 so this option is ignored in this version. A real fix will appear in
883 Automake 1.8. (Debian Bug #206299)
884 * AM_PATH_PYTHON: really check the whole list of interpreters if no
885 argument is given. (PR/399)
886 * Do not warn about leading `_' in variable names, even with -Wportability.
887 * Support user redefinitions of TEXINFO_TEX.
888 * depcomp: support AIX Compiler version 6.
889 * Fix missing rebuilds during `make dist' with BSD make.
890 (Could produce tarballs containing out-of-date files.)
891 * Resurrect multilib support.
892 * Noteworthy manual updates:
893 - Extending aclocal: how to write m4 macros that won't trigger warnings
895 - A Shared Library: Rewrite and split into subsections.
898 * Fix depcomp's icc mode for ICC 7.1.
899 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
900 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
901 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
902 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
903 * Remove Latin-1 characters from elisp-comp.
904 * Update the manual's @dircategory to match the Free Software Directory.
907 * Update install-sh's license to remove an advertising clause.
909 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
910 that caused invalid Makefile.ins to be generated.
911 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
912 * New FAQ entry: renamed objects.
915 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
916 the Emacs implementation)
917 * Fix output of aclocal.m4 dependencies in subdirectories.
918 * Use `mv -f' instead of `mv' in fastdep rules.
919 * Upgrade mdate-sh to work on OS/2.
920 * Don't byte-compile elisp files when ELCFILES is set empty.
921 (this documented feature was broken by 1.7.3)
922 * Diagnose trailing backslashes on last line of Makefile.am.
923 * Diagnose whitespace following trailing backslashes.
924 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
925 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
927 * `make install' will build `BUILT_SOURCES' first.
928 * Minor documentation fixes.
931 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
932 * Query distutils for `pythondir' and `pythonexecdir', instead of
933 using an hardcoded path. This should allow builds on 64-bit
934 distributions that usually use lib64/ instead of lib/.
935 * AM_PATH_PYTHON will also search for python2.3.
936 * elisp files are now built all at once instead of one by one. Besides
937 incurring a speed-up, this is required to support interdependent elisp files.
939 - `make distcheck' will now work in `_inst/' and `_build' instead
940 of `=inst/' and `=build/'
941 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
942 - install/uninstall `*.i[0-9][0-9]'-style info files
943 - more changes that affect only the Automake package (not its output)
944 * Fix some incompatibilities with upcoming perl-5.10.
945 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
948 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
949 is troublesome with gcc and Solaris compilers. (PR/385)
950 - makedepend mode: work with Libtool. (PR/385 too)
952 * better support for unusual gettext setups, such as multiple po/ directories
954 - Flag missing po/ and intl/ directories as warnings, not errors.
955 - Disable these warnings if po/ does not exist.
956 * Noteworthy manual updates:
958 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
960 - Document `AM_YFLAGS = -d'. (PR/382)
963 * Fix installation and uninstallation of Info files built in subdirectories.
964 * Do not run `./configure --with-included-gettext' during `make distcheck'
965 if AM_GNU_GETTEXT([external]) is used.
966 * Correctly uninstall renamed man pages.
967 * Do not strip escaped newline in variables defined in one condition
968 and augmented in another condition.
969 * Fix ansi2knr rules for LIBOBJS sources.
970 * Clean all known Texinfo index files, not only those which appear to
971 be used, because we cannot know wich indexes are used in included files.
972 (PR/375, Debian Bug #168671)
973 * Honor only the first @setfilename seen in a Texinfo file.
974 * Treat "required file X not found" diagnostics as errors (exit status 1).
975 * Don't complain that a required file is not found when it is a Makefile
977 * Don't use single suffix inference rules when building `.info'-less
978 Info files, for the sake of Solaris make.
979 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
980 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
981 * Warn about multiple inference rules when -Wportability is used. (PR/372)
982 * Fix building of deansified files from subdirectories. (PR/370)
983 * Add missing `fi' in the .c->.obj rules.
984 * Improve install-sh to work even when names contain spaces or certain
985 (but not all) shell metachars.
986 * Fix the following spurious failures in the test suite:
987 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
988 * Noteworthy manual updates:
989 - Augment the section about BUILT_SOURCES.
990 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
993 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
995 * Aclocal should now recognize macro names containing parentheses, e.g.
996 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
997 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
999 * Install Python files even if they were built. (PR/369)
1000 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1001 version might not be defined in the latter. (PR/358)
1002 * Reorder arguments passed to a couple of commands, so things works
1003 when POSIXLY_CORRECT=1.
1004 * Fix a regex that can cause Perl to segfault on large input.
1006 * Fix distribution of packages that have some sources defined conditionally,
1007 as in the `Conditional compilation using Automake conditionals' example
1009 * Fix spurious test suite failures on IRIX.
1010 * Don't report a required variable as undefined if it has been
1011 defined conditionally for the "right" conditions.
1012 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1013 `make distcheck' fails.
1014 * Fix distribution of included Makefile fragment, so we don't create
1015 spurious directories in the distribution. (PR/366)
1016 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1019 * Autoconf 2.54 is required.
1020 * `aclocal' and `automake' will no longer warn about obsolete
1021 configure macros. This is done by `autoconf -Wobsolete'.
1022 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1023 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1024 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1025 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1026 `configure.ac' for you.
1027 * Support for per-program and per-library `_CPPFLAGS'.
1028 * New `ctags' target (builds CTAGS files).
1029 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1030 (see `automake --help' or the manual for a list of them).
1031 * Honor the WARNINGS environment variable.
1032 * Omit the call to depcomp when using gcc3: call the compiler directly.
1033 * A new option, std-options, tests that programs support --help and --version
1034 when `make installcheck' is run. This is enabled by --gnits.
1035 * Texinfo rules now support the `ps' and `pdf' targets.
1036 * Info files are now created in the build directory, not the source directory.
1037 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1039 * `make distcheck' will enforce DESTDIR support by attempting
1041 * `+=' can be used in conditionals, even if the augmented variable
1042 was defined for another condition.
1043 * Makefile fragments (inserted with `include') are always distributed.
1044 * Use Autoconf's --trace interface to inspect configure.ac and get
1045 a more accurate view of it.
1046 * Add support for extending aclocal's default macro search path
1047 using a `dirlist' file within the aclocal directory.
1048 * automake --output-dir is deprecated.
1049 * The part of the distcheck target that checks whether uninstall actually
1050 removes all installed files has been moved in a separate target,
1051 distuninstallcheck, so it can be overridden easily.
1055 * Support for AM_INIT_GETTEXT([external])
1056 * Bug fixes, including:
1057 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1058 - nobase_ programs and scripts honor --program-transform correctly.
1059 - Erase configure.lineno during `make distclean'.
1060 - Erase YACC and LEX outputs during `make maintainer-clean'.
1063 * Many bug fixes, including:
1064 - Requiring the current version works.
1065 - Fix "$@" portability issues (for Zsh).
1066 - Fix output of dummy dependency files in presence of post-processed
1068 - Don't compute dependencies in background to avoid races with libtool.
1069 - Fix handling of _OBJECTS variables for targets sharing source variables.
1070 - Check dependency mode for Java when AM_PROG_GCJ is used.
1073 * automake --output-dir is deprecated
1074 * Many bug fixes, including:
1075 - Don't choke on AM_LDFLAGS definitions.
1076 - Clean libtool objects from subdirectories.
1077 - Allow configure variables with reserved suffix and unknown prefix
1078 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1079 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1082 * Autoconf 2.52 is required.
1083 * automake no longer run libtoolize.
1084 This is the job of autoreconf (from GNU Autoconf).
1085 * `dist' generates all the archive flavors, as did `dist-all'.
1086 * `dist-gzip' generates the Gzip tar file only.
1087 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1088 explosion. Makefile.in's keep a reasonable size.
1089 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1090 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1092 * `#line' of Lex and Yacc files are properly set.
1093 * EXTRA_DIST can contain generated directories.
1094 * Support for dot-less extensions in suffix rules.
1095 * The part of the distcheck target that checks whether distclean actually
1096 cleans all built files has been moved in a separate target, distcleancheck,
1097 so it can be overridden easily.
1098 * `make distcheck' will pass additional options defined in
1099 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1100 * Fixed CDPATH portability problems, in particular for MacOS X.
1101 * Fixed handling of nobase_ targets.
1102 * Fixed support of implicit rules leading to .lo objects.
1103 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1104 * Added uninstall-hook target
1105 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1106 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1107 (Note that "pkgname" is not "tarname", see the manual for details.)
1108 It is also possible to pass a list of global Automake options as
1109 first argument to this new form of AM_INIT_AUTOMAKE.
1110 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1111 to be a real assembler.
1112 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1113 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1114 * aclocal and automake are also installed with the version number
1115 appended, and some of the install directory names have changed.
1116 This lets you have multiple versions installed simultaneously.
1117 * Support for parsers and lexers in subdirectories.
1120 * Support for `configure.ac'.
1121 * Support for `else COND', `endif COND' and negated conditions `!COND'.
1122 * `make dist-all' is much faster.
1123 * Allows '@' AC_SUBSTs in macro names.
1124 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
1125 * User-side dependency tracking. Developers no longer need GNU make
1127 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
1128 * Most files are correctly handled if they appear in subdirs
1129 For instance, a _DATA file can appear in a subdir
1130 * GNU tar is no longer required for `make dist'
1131 * Added support for `dist_' and `nodist_' prefixes
1132 * Added support for `nobase_' prefix
1133 * Compiled Java support
1134 * Support for per-executable and per-library compilation flags
1138 * Added support for the Fortran 77 programming language.
1139 * Re-indexed the Automake Texinfo manual.
1140 * Added `AM_FOOFLAGS' variable for each compiler invocation;
1141 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
1142 * Support for latest autoconf, including support for objext
1143 * Can now put `.' in SUBDIRS to control build order
1144 * `include' command and `+=' support for macro assignment
1145 * Dependency tracking no long susceptible to deleted header file problem
1146 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
1151 * Better Cygwin32 support
1152 * Support for suffix rules with _SOURCES variables
1153 * New options `readme-alpha' and `check-news'; Gnits mode sets these
1154 * @LEXLIB@ no longer required when lex source seen
1155 Lex support in `missing', and new lex macro. Update your missing script.
1156 * Built-in support for assembly
1157 * aclocal gives error if `AM_' macro not found
1158 * Passed YFLAGS, not YACCFLAGS, to yacc
1159 * AM_PROG_CC_STDC does not have to come before AC_PROG_CPP
1160 * Dependencies computed as a side effect of compilation
1161 * Preliminary support for Java
1162 * DESTDIR support at "make install" time
1163 * Improved ansi2knr support; you must use the latest ansi2knr.c (included)
1167 * Better DejaGnu support
1168 * Added no-installinfo option
1169 * Added Emacs Lisp support
1170 * Added --no-force option
1171 * Included `aclocal' program
1172 * Automake will now generate rules to regenerate aclocal.m4, if appropriate
1173 * Now uses `AM_' macro names everywhere
1174 * ansi2knr option can have directory prefix (eg `../lib/ansi2knr')
1175 ansi2knr now works correctly on K&R sources
1176 * Better C++, yacc, lex support
1177 * Will compute _DEPENDENCIES variables automatically if not supplied
1178 * Will interpolate $(...) and ${...} when examining contents of a variable
1179 * .deps files now in build directory, not source directory; dependency
1180 handling generally rewritten
1181 * DATA, MANS and BUILT_SOURCES no longer included in distribution
1182 * can now put config.h into a subdir
1183 * Added dist-all target
1184 * Support for install-info program (see texinfo 3.9)
1185 * Support for "yacc -d"
1186 * configure substitutions are automatically discovered and included
1187 in generated Makefile.in
1188 * Special --cygnus mode
1189 * OMIT_DEPENDENCIES can now hold list of dependencies to be omitted
1190 when making distribution. Some dependencies are auto-ignored.
1191 * Changed how libraries are specified in _LIBRARIES variable
1192 * Full libtool support, from Gord Matzigkeit
1193 * No longer have to explicitly touch stamp-h when using AC_CONFIG_HEADER;
1194 AM_CONFIG_HEADER handles it automatically
1195 * Texinfo output files no longer need .info extension
1196 * Added `missing' support
1198 * Conditionals in Makefile.am, from Ian Taylor
1202 * distcheck target runs install and installcheck targets
1203 * Added preliminary support for DejaGnu.
1208 * More libtool fixes from Gord Matzigkeit; libtool support is still
1210 * Added support for jm_MAINTAINER_MODE
1212 * New "distcheck" target
1216 * mkinstalldirs and mdate-sh now appear in directory specified by
1218 * Removed DIST_SUBDIRS, DIST_OTHER
1219 * AC_ARG_PROGRAM only required when an actual program exists
1220 * dist-hook target now run before distribution packaged up; idea from
1221 Dieter Baron. Other hooks exist, too.
1222 * Preliminary (unfinished) support for libtool
1223 * Added short option names.
1224 * Better "dist" support when gluing together multiple packages
1228 * Documentation updates (many from François Pinard)
