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 * Changes to automake:
15 - The automake program can run multiple threads for creating most
16 Makefile.in files concurrently, if at least Perl 5.7.2 is available
17 with interpreter-based threads enabled. Set the environment variable
18 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
19 enable this experimental feature.
21 * Changes to Libtool support:
23 - Libtool generic flags are now passed to the install and uninstall
28 - subdir-object mode works now with Fortran (F77, FC, preprocessed
31 - For files with extension .f90, .f95, .f03, or .f08, the flag
32 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
34 - Files with extension .sx are also treated as preprocessed assembler.
36 - Python 3.0 is supported now, Python releases prior to 2.0 are no
39 - The default source file extension (.c) can be overridden with
40 AM_DEFAULT_SOURCE_EXT now.
42 * Miscellaneous changes:
44 - Automake development is done in a git repository on Savannah now, see
46 http://git.sv.gnu.org/gitweb/?p=automake.git
48 A read-only CVS mirror is provided at
50 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
51 checkout -d automake HEAD
53 - "make dist" can now create lzma-compressed tarballs.
55 - Automake is licensed under GPLv3+. `automake --add-missing' will
56 by default install the GPLv3 file as COPYING if it is missing.
57 Note that Automake will never overwrite an existing COPYING file,
58 even when the `--force-missing' option is used.
60 - Automake ships and installs man pages for automake and aclocal now.
62 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
64 - install-sh supports -C, which does not update the installed file
65 (and its time stamps) if the contents did not change.
67 - The targets `install' and `uninstall' are more efficient now, in that
68 for example multiple files from one Automake variable such as
69 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
70 invocation if they do not have to be renamed.
72 Both install and uninstall may sometimes enter (`cd' into) the target
73 installation directory now, when no build-local scripts are used.
75 For built-in rules, `make install' now fails reliably if installation
76 of a file failed. Conversely, `make uninstall' even succeeds when
77 issued multiple times.
79 These changes may need some adjustments from users: For example,
80 some `install' programs refuse to install multiple copies of the
81 same file in one invocation, so you may need to remove duplicate
82 entries from file lists.
84 Also, within one set of files, say, nobase_data_DATA, the order of
85 installation may be changed, or even unstable among different hosts,
86 due to the use of associative arrays in awk. The increased use of
87 awk matches a similar move in Autoconf to provide for better scaling.
89 Further, most undocumented per-rule install command variables such as
90 binSCRIPT_INSTALL have been removed because they are not needed any
91 more. Packages which use them should be using the appropriate one of
92 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
93 counterpart, depending on the type of files and the need for automatic
94 target directory creation.
96 - The "deleted header file problem" for *.m4 files is avoided by
97 stub rules. This allows `make' to trigger a rerun of `aclocal'
98 also if some previously needed macro file has been removed.
100 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
101 an otherwise up to date tree.
103 - The `color-tests' option causes colored test result output on terminals.
105 - New prefix `notrans_' for manpages which should not be transformed
106 by --program-transform.
108 - New macro AM_COND_IF for conditional evaluation and conditional
111 - For AC_CONFIG_LINKS, if source and destination are equal, do not
112 remove the file in a non-VPATH build. Such setups work with Autoconf
115 - AM_MAINTAINER_MODE now allows for an optional argument specifying
118 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
119 useful especially for multi-line values.
123 * Long standing bugs:
125 - Fix aix dependency tracking for libtool objects.
127 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
128 unnecessary use of the `compile' script.
130 - For nobase_*_LTLIBRARIES with nonempty directory components, the
131 correct `-rpath' argument is used now.
133 - `config.status --file=Makefile depfiles' now also works with the
134 extra quoting used internally by Autoconf 2.62 and newer
135 (it used to work only without the `--file=' bit).
137 * Bugs introduced by 1.10:
139 - Fix output of dummy dependency files in presence of post-processed
140 Makefile.in's again, but also cope with long lines.
142 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
143 that have been declared as programs in the same Makefile.
144 This is for consistency with the analogous change to TESTS in 1.10.
146 - Fix order of standard includes to again be `-I. -I$(srcdir)',
147 followed by directories containing config headers.
151 * Version requirements:
153 - Autoconf 2.60 or greater is required.
155 - Perl 5.6 or greater is required.
157 * Changes to aclocal:
159 - aclocal now also supports -Wmumble and -Wno-mumble options.
161 - `dirlist' entries (for the aclocal search path) may use shell
162 wildcards such as `*', `?', or `[...]'.
164 - aclocal supports an --install option that will cause system-wide
165 third-party macros to be installed in the local directory
166 specified with the first -I flag. This option also uses #serial
167 lines in M4 files to upgrade local macros.
169 The new aclocal options --dry-run and --diff help to review changes
170 before they are installed.
172 - aclocal now outputs an autoconf version check in aclocal.m4 in
173 projects using automake.
175 For a few years, automake and aclocal have been calling autoconf
176 (or its underlying engine autom4te) to accurately retrieve the
177 data they need from configure.ac and its siblings. Doing so can
178 only work if all autotools use the same version of autoconf. For
179 instance a Makefile.in generated by automake for one version of
180 autoconf may stop working if configure is regenerated with another
181 version of autoconf, and vice versa.
183 This new version check ensures that the whole build system has
184 been generated using the same autoconf version.
186 * Support for new Autoconf macros:
188 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
190 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
191 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
192 in different directories. However, only one instance of such a
193 library objects directory is supported.
195 * Change to Libtool support:
197 - Libtool generic flags (those that go before the --mode=MODE option)
198 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
200 * Yacc and Lex changes:
202 - The rebuild rules for distributed Yacc and Lex output will avoid
203 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
206 - ylwrap is now always used for lex and yacc source files,
207 regardless of whether there is more than one source per directory.
211 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
212 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
213 tracking, unlike non-preprocessed assembler (*.s).
215 - subdir-object mode works now with Assembler. Automake assumes
216 that the compiler understands `-c -o'.
218 - Preprocessed assembler (*.S) compilation now also honors
219 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
221 - Improved support for Objective C:
222 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
223 - A new section of the manual documents the support.
225 - New support for Unified Parallel C:
226 - AM_PROG_UPC looks for a UPC compiler.
227 - A new section of the manual documents the support.
229 - Per-target flags are now correctly handled in link rules.
231 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
232 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
233 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
234 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
236 The fix for compiler flags (i.e., using maude_CFLAGS instead of
237 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
238 is expected to work (and actually works during compilation).
240 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
241 "in addition to" breaks backward compatibility with older versions.
242 If your package used both variables, as in
244 AM_LDFLAGS = common flags
246 a_LDFLAGS = more flags
249 and assumed *_LDFLAGS would sum up, you should rewrite it as
251 AM_LDFLAGS = common flags
253 a_LDFLAGS = $(AM_LDFLAGS) more flags
256 This new behavior of *_LDFLAGS is more coherent with other
257 per-target variables, and the way *_LDFLAGS variables were
258 considered internally.
260 * New installation targets:
262 - New targets mandated by GNU Coding Standards:
267 By default they will only install Texinfo manuals.
268 You can customize them with *-local variants:
274 - The undocumented recursive target `uninstall-info' no longer exists.
275 (`uninstall' is in charge of removing all possible documentation
276 flavors, including optional formats such as dvi, ps, or info even
277 when `no-installinfo' is used.)
279 * Miscellaneous changes:
281 - Automake no longer complains if input files for AC_CONFIG_FILES
282 are specified using shell variables.
284 - clean, distribution, or rebuild rules are normally disabled for
285 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
286 AC_CONFIG_LINK specified using shell variables. However, if these
287 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
288 be able to output rules anyway.
289 (See the Automake documentation for AC_CONFIG_FILES.)
291 - $(EXEEXT) is automatically appended to filenames of TESTS
292 that have been declared as programs in the same Makefile.
293 This is mostly useful when some check_PROGRAMS are listed in TESTS.
295 - `-Wportability' has finally been turned on by default for `gnu' and
296 `gnits' strictness. This means, automake will complain about %-rules
297 or $(GNU Make functions) unless you switch to `foreign' strictness or
298 use `-Wno-portability'.
300 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
301 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
302 $(mkdir_p) variable is still defined (to the same value as
303 $(MKDIR_P)) but should be considered obsolete. If you are using
304 $(mkdir_p) in some of your rules, please plan to update them to
305 $(MKDIR_P) at some point.
307 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
308 They still work in this release, but may be withdrawn in a future one.
310 - Inline compilation rules for gcc3-style dependency tracking are
313 - Automake installs a "Hello World!" example package in $(docdir).
314 This example is used throughout the new "Autotools Introduction"
315 chapter of the manual.
319 * Makefile.in bloat reduction:
321 - Inference rules are used to compile sources in subdirectories when
322 the `subdir-objects' option is used and no per-target flags are
323 used. This should reduce the size of some projects a lot, because
324 Automake used to output an explicit rule for each such object in
327 - Automake no longer outputs three rules (.o, .obj, .lo) for each
328 object that must be built with explicit rules. It just outputs
329 the rules required to build the kind of object considered: either
330 the two .o and .obj rules for usual objects, or the .lo rule for
333 * Change to Libtool support:
335 - Libtool tags are used with libtool versions that support them.
336 (I.e., with Libtool 1.5 or greater.)
338 - Automake is now able to handle setups where a libtool library is
339 conditionally installed in different directories, as in
342 lib_LTLIBRARIES = liba.la
344 pkglib_LTLIBRARIES = liba.la
346 liba_la_SOURCES = ...
348 * Changes to aclocal:
350 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
351 really evaluated, before it decides to include them in aclocal.m4.
352 This solves nasty problems with conditional redefinitions of
353 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
354 *.m4 files to be included in any project using these macros.
355 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
356 most famous instance of this bug.)
358 - Do not complain about missing conditionally AC_REQUIREd macros
359 that are not actually used. In 1.8.x aclocal would correctly
360 determine which of these macros were really needed (and include
361 only these in the package); unfortunately it would also require
362 all of them to be present in order to run. This created
363 situations were aclocal would not work on a tarball distributing
364 all the macros it uses. For instance running aclocal on a project
365 containing only the subset of the Gettext macros in use by the
366 project did not work, because gettext conditionally requires other
369 * Portability improvements:
371 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
372 tar-pax. The new option filename-length-max=99 helps diagnosing
373 filenames that are too long for tar-v7. (PR/414)
375 - Variables aumented with `+=' are now automatically flattened (i.e.,
376 trailing backslashes removed) and then wrapped around 80 colummns
377 (adding trailing backslashes). In previous versions, a long series
383 would result in a single-line definition of VAR that could possibly
384 exceed the maximum line length of some make implementations.
386 Non-augmented variables are still output as they are defined in
391 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
392 Works the same as the old Fortran 77 implementation; just replace
393 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
394 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
396 - Support for conditional _LISP.
398 - Support for conditional -hook and -local rules (PR/428).
400 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
402 - Automake will not write any Makefile.ins after the first error it
403 encounters. The previous Makefile.ins (if any) will be left in
404 place. (Warnings will not prevent output, but remember they can
405 be turned into errors with -Werror.)
407 - The restriction that SUBDIRS must contain direct children is gone.
410 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
411 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
415 * Long standing bugs:
417 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
418 so that `make distclean' and `make maintainer-clean' can work.
420 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
422 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
424 - Polish diagnostic when no input file is found.
428 * Long standing bugs:
430 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
431 overridden by the user.
433 - Honor PATH_SEPARATOR in various places of the Automake package, for
436 - Adjust dependency tracking mode detection to ICC 8.0's new output.
439 - Fix install-sh so it can install the `mv' binary... using `mv'.
441 - Fix tru64 dependency tracking for libtool objects.
443 - Work around Exuberant Ctags when creating a TAGS files in a directory
444 without files to scan but with subdirectories to include.
446 * Bugs introduced by 1.8:
448 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
449 not defined in the same conditions as the _LDADD that uses it.
451 - Do not warn when JAVAROOT is overridden, this is legitimate.
455 * Long standing bugs:
457 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
458 or any of the other *dir variables contain a space.
460 Please note that Automake does not and cannot support spaces in
461 filenames that are involved during the build. This change affects
462 only installation paths, so that `make install' does not bomb out
463 in packages configured with
464 ./configure --prefix '/c/Program Files'
466 - Fix the depfiles output so it works with GNU sed (<4.1) even when
467 POSIXLY_CORRECT is set.
469 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
470 since Autoconf 2.54, which defines LIBOBJS itself.
472 - Fix a potential (but unlikely) race condition in parallel elisp
473 builds. (Introduced in 1.7.3.)
475 - Do not assume that users override _DEPENDENCIES in all conditions
476 where Automake will try to define them.
478 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
479 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
482 This fix also affects the $(mkdir_p) variable defined since
483 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
484 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
486 - Secure temporary directory creation in `make distcheck'. (PR/413)
488 - Do not generate two build rules for `parser.h' when the
489 parser appears in two different conditionals.
491 - Work around a Solaris 8 /bin/sh bug in the test for dependency
492 checking. Usually ./configure will not pick this shell; so this
493 fix only helps cases where the shell is forced to /bin/sh.
495 * Bugs introduced by 1.8:
497 - In some situations (hand-written `m4_include's), aclocal would
498 call the `File::Spec->rel2abs' method, which was only introduced
499 in Perl 5.6. This new version reestablish support Perl 5.005.
501 It is likely that the next major Automake releases will require at
502 least Perl 5.6. Consider upgrading your development environment
503 if you are still using the five-year-old Perl 5.005.
505 - Automake would sometimes fail to define rules for targets listed
506 in variables defined in multiple conditions. For instance on
512 it would define only the `a.$(OBJEXT): a.c' rule and omit the
513 `b.$(OBJEXT): b.c' rule.
515 * New sections in manual:
517 - Third-Party Makefiles: how to interface third party Makefiles.
518 - Upgrading: upgrading packages to newer Automake versions.
519 - Multiple Outputs: handling tools that produce many outputs.
523 * A (well known) portability bug slipped in the changes made to
524 install-sh in Automake 1.8.1. The broken install-sh would refuse to
525 install anything on Tru64.
527 * Fix install rules for conditionally built python files. (This never
532 * Bugs introduced by 1.8:
534 - Fix Config.pm import error with old Perl versions (at least
535 5.005_03). One symptom is that aclocal could not find its macro
538 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
539 created by `make install' are always world readable, even if the
540 installer happens to have an overly restrictive umask (e.g. 077).
541 This was a mistake and has been reverted. There are at least two
542 reasons why we must not use `-m 0755':
543 - it causes special bits like SGID to be ignored,
544 - it may be too restrictive (some setups expect 775 directories).
546 - Fix aclocal to honor definitions located in files which have been
547 m4_included manually. aclocal 1.8 had been updated to check
548 m4_included files for new requirements, but forgot that these
549 m4_included files can also provide new definitions.
551 Note that if you have such a setup, we recommend you get rid of
552 it. In the past, there was a reason to m4_include files manually:
553 aclocal used to duplicate entire M4 files into aclocal.m4, even
554 files that were distributed. Some packages were therefore
555 m4_including the distributed file directly, and playing some
556 tricks to ensure aclocal would not copy that file to aclocal.m4,
557 in order to limit the amount of duplication. Since aclocal 1.8.x
558 will precisely output m4_includes for local M4 files, we recommend
559 that you clean up your setup, removing all manual m4_includes and
560 letting aclocal output them.
562 - Output detailed menus in the Info version if the Automake manual,
563 so that Emacs can locate the indexes.
565 - configure.ac and configure were listed twice in DIST_COMMON (an
566 internal variable where Automake lists configury files to
567 distribute). This was harmless, but unaesthetic.
569 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
570 This was an issue only in the Automake package itself, not in
573 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
574 DEST:SRC. This was wrong, as some packages do
575 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
578 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
579 argument. This caused two kinds of failures:
580 - Rules installing data in a conditionally defined directory
581 failed when that directory was undefined. In this case no
582 argument was supplied.
583 - `make installdirs' failed, because several directories were
584 passed to $(mkdir_p). This was an issue only on platform
585 were $(mkdir_p) is implemented with `install-sh -d'.
586 $(mkdir_p) as been changed to accept 0 or more arguments, as
589 * Long-standing bugs:
591 - Fix an unexpected diagnostic occurring when users attempt
592 to override some internal variables that Automake appends to.
594 - aclocal now scans configure.ac for macro definitions (PR/319).
596 - Fix a portability issue with OSF1/Tru64 Make. If a directory
597 distributes files which are outside itself (this usually occurs
598 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
599 from a parent package), then `make distcheck' fails due to an
600 optimization performed by OSF1/Tru64 Make in its VPATH handling.
601 (tests/subpkg2.test failure)
603 - Fix another portability issue with Sun and OSF1/Tru64 Make.
604 In a VPATH-build configuration, `make install' would install
605 nobase_ files to wrong locations.
607 - Fix a Perl `uninitialized value' diagnostic occurring when
608 automake complains that a Texinfo file does not have a
609 @setfilename statement.
611 - Erase config.status.lineno during `make distclean'. This file
612 can be created by config.status. Automake already knew about
613 configure.lineno, but forgot config.status.lineno.
615 - Distribute all files, even those which are built and installed
616 conditionally. This change affects files listed in conditionally
617 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
618 as well as those listed in conditionally defined dist_*_DATA,
619 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
621 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
622 doesn't conform to POSIX.
624 - Normalize help strings for configure variables and options added
629 - Check for python2.4 in AM_PATH_PYTHON.
631 * Spurious failures in test suite:
633 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
634 tests/ltconv.test: fix failures with CVS Libtool.
635 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
636 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
637 fix failures with old Texinfo versions.
643 - The NEWS file is more verbose.
647 - Autoconf 2.58 or greater is required.
651 - Default source file names in the absence of a _SOURCES declaration
652 are made by removing any target extension before appending `.c', so
653 to make the libtool module `foo.la' from `foo.c', you only need to
656 lib_LTLIBRARIES = foo.la
657 foo_la_LDFLAGS = -module
659 For backward compatibility, foo_la.c will be used instead of
660 foo.c if this file exists or is the explicit target of a rule.
661 However -Wobsolete will warn about this deprecated naming.
663 - AR's `cru' flags are now set in a global ARFLAGS variable instead
664 of being hard-coded in each $(AR) invocation, so they can be
665 substituted from configure.ac. This has been requested by people
666 dealing with non-POSIX ar implementations.
668 - New warning option: -Woverride. This will warn about any user
669 target or variable definitions which override Automake
672 - Texinfo rules back up and restore info files when makeinfo fails.
674 - Texinfo rules now support the `html' target.
675 Running this requires Texinfo 4.0 or greater.
677 `html' is a new recursive target, so if your package mixes
678 hand-crafted `Makefile.in's with Automake-generated
679 `Makefile.in's, you should adjust the former to support (or
680 ignore) this target so that `make html' recurses successfully. If
681 you had a custom `html' rule in your `Makefile.am', it's better to
682 rename it as `html-local', otherwise your rule will override
683 Automake's new rule (you can check that by running `automake
684 -Woverride') and that will stop the recursion to subdirectories.
686 Last but not least, this `html' rule is declared PHONY, even when
687 overridden. Fortunately, it appears that few packages use a
688 non-PHONY `html' rule.
690 - Any file which is m4_included from configure.ac will appear as a
691 configure and Makefile.in dependency, and will be automatically
694 - The rules for rebuilding Makefiles and Makefile.ins will now
695 rebuild all Makefiles and all Makefile.ins at once when one of
696 configure's dependencies has changed. This is considerably faster
697 than previous implementations, where config.status and automake
698 were run separately in each directory (this still happens when you
699 change a Makefile.am locally, without touching configure.ac or
700 friends). Doing this also solves a longstanding issue: these
701 rebuild rules failed to work when adding new directories to the
702 tree, forcing you to run automake manually.
704 - For similar reasons, the rules to rebuild configure,
705 config.status, and aclocal.m4 are now defined in all directories.
706 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
707 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
708 should better define them in all directories. This is easily done
709 using an AC_SUBST (make sure you prefix these dependencies with
710 $(top_srcdir) since this variable will appear at different
711 levels of the build tree).
713 - aclocal will now use `m4_include' instead of copying local m4
714 files into aclocal.m4. (Local m4 files are those you ship with
715 your project, other files will be copied as usual.)
717 Because m4_included files are automatically distributed, it means
718 for most projects there is no point in EXTRA_DISTing the list of
719 m4 files which are used. (You can probably get rid of
720 m4/Makefile.am if you had one.)
722 - aclocal will avoid touching aclocal.m4 when possible, so that
723 Autom4te's cache isn't needlessly invalidated. This behavior can
724 be switched off with the new `--force' option.
726 - aclocal now uses Autoconf's --trace to detect macros which are
727 actually used and will no longer include unused macros simply
728 because they where mentioned. This was often the case for macros
729 called conditionally.
731 - New options no-dist and no-dist-gzip.
733 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
734 py-compile, and ylwrap, now all understand --version and --help.
736 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
737 links as part of the distclean target and including source files in
740 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
741 argument. The latter can be used to override the default behavior
744 - Automake will exit with $? = 63 on version mismatch. (So does
745 Autoconf 2.58) missing knows this, and in this case it will
746 emulate the tools as if they were absent. Because older versions
747 of Automake and Autoconf did not use this exit code, this change
748 will only be useful in projects generated with future versions of
751 - When using AC_CONFIG_FILES with multiple input files, Automake
752 generates the first ".in" input file for which a ".am" exists.
753 (Former versions would try to use only the first input file.)
755 - lisp_DATA is now allowed. If you are using the empty ELCFILES
756 idiom to disable byte-compilation of lisp_LISP files, it is
757 recommended that you switch to using lisp_DATA. Note that
758 this is not strictly equivalent: lisp_DATA will install elisp
759 files even if emacs is not installed, while *_LISP do not
760 install anything unless emacs is found.
762 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
763 available. This selection is achieved through the Makefile
764 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
765 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
766 `$(install_sh) -m 0755 -d'.
770 - Because `mkdir -p' is available on most platforms, and we can use
771 `install-sh -d' when it is not, the use of the mkinstalldirs
772 script is being phased out. `automake --add-missing' no longer
773 installs it, and if you remove mkinstalldirs from your package,
774 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
776 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
777 gettextize and autopoint will install it when needed. Automake
778 will continue to define the $(mkinstalldirs) and to distribute
779 mkinstalldirs when this script is in the source tree.
781 - AM_PROG_CC_STDC is now empty. The content of this macro was
782 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
783 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
784 renaming should be safe, even if you have to support several,
785 versions of Automake, because AC_PROG_CC defines this variable
786 since Autoconf 2.54.)
788 - Some users where using the undocumented ACLOCAL_M4_SOURCES
789 variable to override the aclocal.m4 dependencies computed
790 (inaccurately) by older versions of Automake. Because Automake
791 now tracks configure's m4 dependencies accurately (see m4_include
792 above), the use of ACLOCAL_M4_SOURCES should be considered
793 obsolete and will be flagged as such when running `automake
798 - Defining programs conditionally using Automake conditionals no
799 longer leads to a combinatorial explosion. The following
800 construct used to be troublesome when used with dozens of
815 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
817 - Due to implementation constraints, previous versions of Automake
818 proscribed multiple conditional definitions of some variables
828 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
829 This restriction has been lifted, and these variables now
830 support multiple conditional definitions as do other variables.
832 - Cleanup the definitions of $(distdir) and $(top_distdir).
833 $(top_distdir) now points to the root of the distribution
834 directory created during `make dist', as it did in Automake 1.4,
835 not to the root of the build tree as it did in intervening
836 versions. Furthermore these two variables are now only defined in
837 the top level Makefile, and passed to sub-directories when running
840 - The --no-force option now correctly checks the Makefile.in's
841 dependencies before deciding not to update it.
843 - Do not assume that make files are called Makefile in cleaning rules.
845 - Update .info files in the source tree, not in the build tree. This
846 is what the GNU Coding Standard recommend. Only Automake 1.7.x
847 used to update these files in the build tree (previous versions did
848 it in the source tree too), and it caused several problems, varying
849 from mere annoyance to portability issues.
851 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
852 when --add-missing and --force-missing are used. For backward
853 compatibility --add-missing will continue to install COPYING (in
854 `gnu' strictness) when none of these three files exist, but this
855 use is deprecated: you should better choose a license yourself and
856 install it once for all in your source tree (and in your code
859 - Fix ylwrap so that it does not overwrite header files that haven't
860 changed, as the inline rule already does.
862 - User-defined rules override automake-defined rules for the same
863 targets, even when rules do not have commands. This is not new
864 (and was documented), however some of the automake-generated
865 rules have escaped this principle in former Automake versions.
866 Rules for the following targets are affected by this fix:
868 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
869 info, info-am, install-data-am, install-exec-am, install-info,
870 install-info-am, install-man, installcheck-am, maintainer-clean,
871 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
872 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
874 Practically it means that an attempt to supplement the dependencies
875 of some target, as in
879 will now *silently override* the automake definition of the
880 rule for this target. Running `automake -Woverride' will diagnose
881 all such overriding definitions.
883 It should be noted that almost all these targets support a *-local
884 variant that is meant to supplement the automake-defined rule
885 (See node `Extending' in the manual). The above rule should
888 clean-local: my-clean-rule
890 These *-local targets have been documented since at least
891 Automake 1.2, so you should not fear the change if you have
892 to support multiple automake versions.
896 - The Automake manual is now distributed under the terms of the GNU FDL.
898 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
900 - core dumps are no longer removed by the cleaning rules. There are
901 at least three reasons for this:
902 1. These files should not be created by any build step,
903 so their removal do not fit any of the cleaning rules.
904 Actually, they may be precious to the developer.
905 2. If such file is created during a build, then it's clearly a
906 bug Automake should not hide. Not removing the file will
907 cause `make distcheck' to complain about its presence.
908 3. Operating systems have different naming conventions for
909 core dump files. A core file on one system might be a
910 completely legitimate data file on another system.
912 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
913 defined by Automake. This means that any definition in the
914 environment will be used, unless overridden in the Makefile.am or
915 on the command line. The old behavior, where these variables were
916 defined empty in each Makefile, can be obtained by AC_SUBSTing or
917 AC_ARG_VARing each variable from configure.ac.
919 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
920 documented. (The is not a new feature, these variables have
921 been there since at least Automake 1.4.)
924 * Fix install-strip to work with nobase_ binaries.
925 * Fix renaming of #line directives in ylwrap.
926 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
929 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
930 * Fix detection of Debian's install-info, broken since version 1.5.
931 (Debian bug #213524).
932 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
933 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
936 * The implementation of automake's --no-force option is unreliable,
937 so this option is ignored in this version. A real fix will appear in
938 Automake 1.8. (Debian Bug #206299)
939 * AM_PATH_PYTHON: really check the whole list of interpreters if no
940 argument is given. (PR/399)
941 * Do not warn about leading `_' in variable names, even with -Wportability.
942 * Support user redefinitions of TEXINFO_TEX.
943 * depcomp: support AIX Compiler version 6.
944 * Fix missing rebuilds during `make dist' with BSD make.
945 (Could produce tarballs containing out-of-date files.)
946 * Resurrect multilib support.
947 * Noteworthy manual updates:
948 - Extending aclocal: how to write m4 macros that won't trigger warnings
950 - A Shared Library: Rewrite and split into subsections.
953 * Fix depcomp's icc mode for ICC 7.1.
954 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
955 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
956 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
957 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
958 * Remove Latin-1 characters from elisp-comp.
959 * Update the manual's @dircategory to match the Free Software Directory.
962 * Update install-sh's license to remove an advertising clause.
964 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
965 that caused invalid Makefile.ins to be generated.
966 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
967 * New FAQ entry: renamed objects.
970 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
971 the Emacs implementation)
972 * Fix output of aclocal.m4 dependencies in subdirectories.
973 * Use `mv -f' instead of `mv' in fastdep rules.
974 * Upgrade mdate-sh to work on OS/2.
975 * Don't byte-compile elisp files when ELCFILES is set empty.
976 (this documented feature was broken by 1.7.3)
977 * Diagnose trailing backslashes on last line of Makefile.am.
978 * Diagnose whitespace following trailing backslashes.
979 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
980 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
982 * `make install' will build `BUILT_SOURCES' first.
983 * Minor documentation fixes.
986 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
987 * Query distutils for `pythondir' and `pythonexecdir', instead of
988 using an hardcoded path. This should allow builds on 64-bit
989 distributions that usually use lib64/ instead of lib/.
990 * AM_PATH_PYTHON will also search for python2.3.
991 * elisp files are now built all at once instead of one by one. Besides
992 incurring a speed-up, this is required to support interdependent elisp files.
994 - `make distcheck' will now work in `_inst/' and `_build' instead
995 of `=inst/' and `=build/'
996 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
997 - install/uninstall `*.i[0-9][0-9]'-style info files
998 - more changes that affect only the Automake package (not its output)
999 * Fix some incompatibilities with upcoming perl-5.10.
1000 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1001 PACKAGE and VERSION.
1003 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1004 is troublesome with gcc and Solaris compilers. (PR/385)
1005 - makedepend mode: work with Libtool. (PR/385 too)
1007 * better support for unusual gettext setups, such as multiple po/ directories
1009 - Flag missing po/ and intl/ directories as warnings, not errors.
1010 - Disable these warnings if po/ does not exist.
1011 * Noteworthy manual updates:
1013 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1015 - Document `AM_YFLAGS = -d'. (PR/382)
1017 Bugs fixed in 1.7.2:
1018 * Fix installation and uninstallation of Info files built in subdirectories.
1019 * Do not run `./configure --with-included-gettext' during `make distcheck'
1020 if AM_GNU_GETTEXT([external]) is used.
1021 * Correctly uninstall renamed man pages.
1022 * Do not strip escaped newline in variables defined in one condition
1023 and augmented in another condition.
1024 * Fix ansi2knr rules for LIBOBJS sources.
1025 * Clean all known Texinfo index files, not only those which appear to
1026 be used, because we cannot know wich indexes are used in included files.
1027 (PR/375, Debian Bug #168671)
1028 * Honor only the first @setfilename seen in a Texinfo file.
1029 * Treat "required file X not found" diagnostics as errors (exit status 1).
1030 * Don't complain that a required file is not found when it is a Makefile
1032 * Don't use single suffix inference rules when building `.info'-less
1033 Info files, for the sake of Solaris make.
1034 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1035 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1036 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1037 * Fix building of deansified files from subdirectories. (PR/370)
1038 * Add missing `fi' in the .c->.obj rules.
1039 * Improve install-sh to work even when names contain spaces or certain
1040 (but not all) shell metachars.
1041 * Fix the following spurious failures in the test suite:
1042 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1043 * Noteworthy manual updates:
1044 - Augment the section about BUILT_SOURCES.
1045 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1047 Bugs fixed in 1.7.1:
1048 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1050 * Aclocal should now recognize macro names containing parentheses, e.g.
1051 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1052 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1054 * Install Python files even if they were built. (PR/369)
1055 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1056 version might not be defined in the latter. (PR/358)
1057 * Reorder arguments passed to a couple of commands, so things works
1058 when POSIXLY_CORRECT=1.
1059 * Fix a regex that can cause Perl to segfault on large input.
1061 * Fix distribution of packages that have some sources defined conditionally,
1062 as in the `Conditional compilation using Automake conditionals' example
1064 * Fix spurious test suite failures on IRIX.
1065 * Don't report a required variable as undefined if it has been
1066 defined conditionally for the "right" conditions.
1067 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1068 `make distcheck' fails.
1069 * Fix distribution of included Makefile fragment, so we don't create
1070 spurious directories in the distribution. (PR/366)
1071 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1074 * Autoconf 2.54 is required.
1075 * `aclocal' and `automake' will no longer warn about obsolete
1076 configure macros. This is done by `autoconf -Wobsolete'.
1077 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1078 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1079 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1080 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1081 `configure.ac' for you.
1082 * Support for per-program and per-library `_CPPFLAGS'.
1083 * New `ctags' target (builds CTAGS files).
1084 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1085 (see `automake --help' or the manual for a list of them).
1086 * Honor the WARNINGS environment variable.
1087 * Omit the call to depcomp when using gcc3: call the compiler directly.
1088 * A new option, std-options, tests that programs support --help and --version
1089 when `make installcheck' is run. This is enabled by --gnits.
1090 * Texinfo rules now support the `ps' and `pdf' targets.
1091 * Info files are now created in the build directory, not the source directory.
1092 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1094 * `make distcheck' will enforce DESTDIR support by attempting
1096 * `+=' can be used in conditionals, even if the augmented variable
1097 was defined for another condition.
1098 * Makefile fragments (inserted with `include') are always distributed.
1099 * Use Autoconf's --trace interface to inspect configure.ac and get
1100 a more accurate view of it.
1101 * Add support for extending aclocal's default macro search path
1102 using a `dirlist' file within the aclocal directory.
1103 * automake --output-dir is deprecated.
1104 * The part of the distcheck target that checks whether uninstall actually
1105 removes all installed files has been moved in a separate target,
1106 distuninstallcheck, so it can be overridden easily.
1110 * Support for AM_INIT_GETTEXT([external])
1111 * Bug fixes, including:
1112 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1113 - nobase_ programs and scripts honor --program-transform correctly.
1114 - Erase configure.lineno during `make distclean'.
1115 - Erase YACC and LEX outputs during `make maintainer-clean'.
1118 * Many bug fixes, including:
1119 - Requiring the current version works.
1120 - Fix "$@" portability issues (for Zsh).
1121 - Fix output of dummy dependency files in presence of post-processed
1123 - Don't compute dependencies in background to avoid races with libtool.
1124 - Fix handling of _OBJECTS variables for targets sharing source variables.
1125 - Check dependency mode for Java when AM_PROG_GCJ is used.
1128 * automake --output-dir is deprecated
1129 * Many bug fixes, including:
1130 - Don't choke on AM_LDFLAGS definitions.
1131 - Clean libtool objects from subdirectories.
1132 - Allow configure variables with reserved suffix and unknown prefix
1133 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1134 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1137 * Autoconf 2.52 is required.
1138 * automake no longer run libtoolize.
1139 This is the job of autoreconf (from GNU Autoconf).
1140 * `dist' generates all the archive flavors, as did `dist-all'.
1141 * `dist-gzip' generates the Gzip tar file only.
1142 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1143 explosion. Makefile.in's keep a reasonable size.
1144 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1145 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1147 * `#line' of Lex and Yacc files are properly set.
1148 * EXTRA_DIST can contain generated directories.
1149 * Support for dot-less extensions in suffix rules.
1150 * The part of the distcheck target that checks whether distclean actually
1151 cleans all built files has been moved in a separate target, distcleancheck,
1152 so it can be overridden easily.
1153 * `make distcheck' will pass additional options defined in
1154 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1155 * Fixed CDPATH portability problems, in particular for MacOS X.
1156 * Fixed handling of nobase_ targets.
1157 * Fixed support of implicit rules leading to .lo objects.
1158 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1159 * Added uninstall-hook target
1160 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1161 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1162 (Note that "pkgname" is not "tarname", see the manual for details.)
1163 It is also possible to pass a list of global Automake options as
1164 first argument to this new form of AM_INIT_AUTOMAKE.
1165 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1166 to be a real assembler.
1167 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1168 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1169 * aclocal and automake are also installed with the version number
1170 appended, and some of the install directory names have changed.
1171 This lets you have multiple versions installed simultaneously.
1172 * Support for parsers and lexers in subdirectories.
1175 * Support for `configure.ac'.
1176 * Support for `else COND', `endif COND' and negated conditions `!COND'.
1177 * `make dist-all' is much faster.
1178 * Allows '@' AC_SUBSTs in macro names.
1179 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
1180 * User-side dependency tracking. Developers no longer need GNU make
1182 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
1183 * Most files are correctly handled if they appear in subdirs
1184 For instance, a _DATA file can appear in a subdir
1185 * GNU tar is no longer required for `make dist'
1186 * Added support for `dist_' and `nodist_' prefixes
1187 * Added support for `nobase_' prefix
1188 * Compiled Java support
1189 * Support for per-executable and per-library compilation flags
1193 * Added support for the Fortran 77 programming language.
1194 * Re-indexed the Automake Texinfo manual.
1195 * Added `AM_FOOFLAGS' variable for each compiler invocation;
1196 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
1197 * Support for latest autoconf, including support for objext
1198 * Can now put `.' in SUBDIRS to control build order
1199 * `include' command and `+=' support for macro assignment
1200 * Dependency tracking no long susceptible to deleted header file problem
1201 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
1206 * Better Cygwin32 support
1207 * Support for suffix rules with _SOURCES variables
1208 * New options `readme-alpha' and `check-news'; Gnits mode sets these
1209 * @LEXLIB@ no longer required when lex source seen
1210 Lex support in `missing', and new lex macro. Update your missing script.
1211 * Built-in support for assembly
1212 * aclocal gives error if `AM_' macro not found
1213 * Passed YFLAGS, not YACCFLAGS, to yacc
1214 * AM_PROG_CC_STDC does not have to come before AC_PROG_CPP
1215 * Dependencies computed as a side effect of compilation
1216 * Preliminary support for Java
