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 - The `color-tests' option causes colored test result output on terminals.
60 - New prefix `notrans_' for manpages which should not be transformed
61 by --program-transform.
63 - New macro AM_COND_IF for conditional evaluation and conditional
66 - For AC_CONFIG_LINKS, if source and destination are equal, do not
67 remove the file in a non-VPATH build. Such setups work with Autoconf
74 - Fix aix dependency tracking for libtool objects.
76 * Bugs introduced by 1.10:
78 - Fix output of dummy dependency files in presence of post-processed
79 Makefile.in's again, but also cope with long lines.
81 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
82 that have been declared as programs in the same Makefile.
83 This is for consistency with the analogous change to TESTS in 1.10.
85 - Fix order of standard includes to again be `-I. -I$(srcdir)',
86 followed by directories containing config headers.
90 * Version requirements:
92 - Autoconf 2.60 or greater is required.
94 - Perl 5.6 or greater is required.
98 - aclocal now also supports -Wmumble and -Wno-mumble options.
100 - `dirlist' entries (for the aclocal search path) may use shell
101 wildcards such as `*', `?', or `[...]'.
103 - aclocal supports an --install option that will cause system-wide
104 third-party macros to be installed in the local directory
105 specified with the first -I flag. This option also uses #serial
106 lines in M4 files to upgrade local macros.
108 The new aclocal options --dry-run and --diff help to review changes
109 before they are installed.
111 - aclocal now outputs an autoconf version check in aclocal.m4 in
112 projects using automake.
114 For a few years, automake and aclocal have been calling autoconf
115 (or its underlying engine autom4te) to accurately retrieve the
116 data they need from configure.ac and its siblings. Doing so can
117 only work if all autotools use the same version of autoconf. For
118 instance a Makefile.in generated by automake for one version of
119 autoconf may stop working if configure is regenerated with another
120 version of autoconf, and vice versa.
122 This new version check ensures that the whole build system has
123 been generated using the same autoconf version.
125 * Support for new Autoconf macros:
127 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
129 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
130 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
131 in different directories. However, only one instance of such a
132 library objects directory is supported.
134 * Change to Libtool support:
136 - Libtool generic flags (those that go before the --mode=MODE option)
137 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
139 * Yacc and Lex changes:
141 - The rebuild rules for distributed Yacc and Lex output will avoid
142 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
145 - ylwrap is now always used for lex and yacc source files,
146 regardless of whether there is more than one source per directory.
150 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
151 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
152 tracking, unlike non-preprocessed assembler (*.s).
154 - subdir-object mode works now with Assembler. Automake assumes
155 that the compiler understands `-c -o'.
157 - Preprocessed assembler (*.S) compilation now also honors
158 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
160 - Improved support for Objective C:
161 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
162 - A new section of the manual documents the support.
164 - New support for Unified Parallel C:
165 - AM_PROG_UPC looks for a UPC compiler.
166 - A new section of the manual documents the support.
168 - Per-target flags are now correctly handled in link rules.
170 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
171 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
172 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
173 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
175 The fix for compiler flags (i.e., using maude_CFLAGS instead of
176 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
177 is expected to work (and actually works during compilation).
179 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
180 "in addition to" breaks backward compatibility with older versions.
181 If your package used both variables, as in
183 AM_LDFLAGS = common flags
185 a_LDFLAGS = more flags
188 and assumed *_LDFLAGS would sum up, you should rewrite it as
190 AM_LDFLAGS = common flags
192 a_LDFLAGS = $(AM_LDFLAGS) more flags
195 This new behavior of *_LDFLAGS is more coherent with other
196 per-target variables, and the way *_LDFLAGS variables were
197 considered internally.
199 * New installation targets:
201 - New targets mandated by GNU Coding Standards:
206 By default they will only install Texinfo manuals.
207 You can customize them with *-local variants:
213 - The undocumented recursive target `uninstall-info' no longer exists.
214 (`uninstall' is in charge of removing all possible documentation
215 flavors, including optional formats such as dvi, ps, or info even
216 when `no-installinfo' is used.)
218 * Miscellaneous changes:
220 - Automake no longer complains if input files for AC_CONFIG_FILES
221 are specified using shell variables.
223 - clean, distribution, or rebuild rules are normally disabled for
224 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
225 AC_CONFIG_LINK specified using shell variables. However, if these
226 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
227 be able to output rules anyway.
228 (See the Automake documentation for AC_CONFIG_FILES.)
230 - $(EXEEXT) is automatically appended to filenames of TESTS
231 that have been declared as programs in the same Makefile.
232 This is mostly useful when some check_PROGRAMS are listed in TESTS.
234 - `-Wportability' has finally been turned on by default for `gnu' and
235 `gnits' strictness. This means, automake will complain about %-rules
236 or $(GNU Make functions) unless you switch to `foreign' strictness or
237 use `-Wno-portability'.
239 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
240 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
241 $(mkdir_p) variable is still defined (to the same value as
242 $(MKDIR_P)) but should be considered obsolete. If you are using
243 $(mkdir_p) in some of your rules, please plan to update them to
244 $(MKDIR_P) at some point.
246 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
247 They still work in this release, but may be withdrawn in a future one.
249 - Inline compilation rules for gcc3-style dependency tracking are
252 - Automake installs a "Hello World!" example package in $(docdir).
253 This example is used throughout the new "Autotools Introduction"
254 chapter of the manual.
258 * Makefile.in bloat reduction:
260 - Inference rules are used to compile sources in subdirectories when
261 the `subdir-objects' option is used and no per-target flags are
262 used. This should reduce the size of some projects a lot, because
263 Automake used to output an explicit rule for each such object in
266 - Automake no longer outputs three rules (.o, .obj, .lo) for each
267 object that must be built with explicit rules. It just outputs
268 the rules required to build the kind of object considered: either
269 the two .o and .obj rules for usual objects, or the .lo rule for
272 * Change to Libtool support:
274 - Libtool tags are used with libtool versions that support them.
275 (I.e., with Libtool 1.5 or greater.)
277 - Automake is now able to handle setups where a libtool library is
278 conditionally installed in different directories, as in
281 lib_LTLIBRARIES = liba.la
283 pkglib_LTLIBRARIES = liba.la
285 liba_la_SOURCES = ...
287 * Changes to aclocal:
289 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
290 really evaluated, before it decides to include them in aclocal.m4.
291 This solves nasty problems with conditional redefinitions of
292 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
293 *.m4 files to be included in any project using these macros.
294 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
295 most famous instance of this bug.)
297 - Do not complain about missing conditionally AC_REQUIREd macros
298 that are not actually used. In 1.8.x aclocal would correctly
299 determine which of these macros were really needed (and include
300 only these in the package); unfortunately it would also require
301 all of them to be present in order to run. This created
302 situations were aclocal would not work on a tarball distributing
303 all the macros it uses. For instance running aclocal on a project
304 containing only the subset of the Gettext macros in use by the
305 project did not work, because gettext conditionally requires other
308 * Portability improvements:
310 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
311 tar-pax. The new option filename-length-max=99 helps diagnosing
312 filenames that are too long for tar-v7. (PR/414)
314 - Variables aumented with `+=' are now automatically flattened (i.e.,
315 trailing backslashes removed) and then wrapped around 80 colummns
316 (adding trailing backslashes). In previous versions, a long series
322 would result in a single-line definition of VAR that could possibly
323 exceed the maximum line length of some make implementations.
325 Non-augmented variables are still output as they are defined in
330 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
331 Works the same as the old Fortran 77 implementation; just replace
332 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
333 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
335 - Support for conditional _LISP.
337 - Support for conditional -hook and -local rules (PR/428).
339 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
341 - Automake will not write any Makefile.ins after the first error it
342 encounters. The previous Makefile.ins (if any) will be left in
343 place. (Warnings will not prevent output, but remember they can
344 be turned into errors with -Werror.)
346 - The restriction that SUBDIRS must contain direct children is gone.
349 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
350 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
354 * Long standing bugs:
356 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
357 so that `make distclean' and `make maintainer-clean' can work.
359 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
361 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
363 - Polish diagnostic when no input file is found.
367 * Long standing bugs:
369 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
370 overridden by the user.
372 - Honor PATH_SEPARATOR in various places of the Automake package, for
375 - Adjust dependency tracking mode detection to ICC 8.0's new output.
378 - Fix install-sh so it can install the `mv' binary... using `mv'.
380 - Fix tru64 dependency tracking for libtool objects.
382 - Work around Exuberant Ctags when creating a TAGS files in a directory
383 without files to scan but with subdirectories to include.
385 * Bugs introduced by 1.8:
387 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
388 not defined in the same conditions as the _LDADD that uses it.
390 - Do not warn when JAVAROOT is overridden, this is legitimate.
394 * Long standing bugs:
396 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
397 or any of the other *dir variables contain a space.
399 Please note that Automake does not and cannot support spaces in
400 filenames that are involved during the build. This change affects
401 only installation paths, so that `make install' does not bomb out
402 in packages configured with
403 ./configure --prefix '/c/Program Files'
405 - Fix the depfiles output so it works with GNU sed (<4.1) even when
406 POSIXLY_CORRECT is set.
408 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
409 since Autoconf 2.54, which defines LIBOBJS itself.
411 - Fix a potential (but unlikely) race condition in parallel elisp
412 builds. (Introduced in 1.7.3.)
414 - Do not assume that users override _DEPENDENCIES in all conditions
415 where Automake will try to define them.
417 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
418 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
421 This fix also affects the $(mkdir_p) variable defined since
422 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
423 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
425 - Secure temporary directory creation in `make distcheck'. (PR/413)
427 - Do not generate two build rules for `parser.h' when the
428 parser appears in two different conditionals.
430 - Work around a Solaris 8 /bin/sh bug in the test for dependency
431 checking. Usually ./configure will not pick this shell; so this
432 fix only helps cases where the shell is forced to /bin/sh.
434 * Bugs introduced by 1.8:
436 - In some situations (hand-written `m4_include's), aclocal would
437 call the `File::Spec->rel2abs' method, which was only introduced
438 in Perl 5.6. This new version reestablish support Perl 5.005.
440 It is likely that the next major Automake releases will require at
441 least Perl 5.6. Consider upgrading your development environment
442 if you are still using the five-year-old Perl 5.005.
444 - Automake would sometimes fail to define rules for targets listed
445 in variables defined in multiple conditions. For instance on
451 it would define only the `a.$(OBJEXT): a.c' rule and omit the
452 `b.$(OBJEXT): b.c' rule.
454 * New sections in manual:
456 - Third-Party Makefiles: how to interface third party Makefiles.
457 - Upgrading: upgrading packages to newer Automake versions.
458 - Multiple Outputs: handling tools that produce many outputs.
462 * A (well known) portability bug slipped in the changes made to
463 install-sh in Automake 1.8.1. The broken install-sh would refuse to
464 install anything on Tru64.
466 * Fix install rules for conditionally built python files. (This never
471 * Bugs introduced by 1.8:
473 - Fix Config.pm import error with old Perl versions (at least
474 5.005_03). One symptom is that aclocal could not find its macro
477 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
478 created by `make install' are always world readable, even if the
479 installer happens to have an overly restrictive umask (e.g. 077).
480 This was a mistake and has been reverted. There are at least two
481 reasons why we must not use `-m 0755':
482 - it causes special bits like SGID to be ignored,
483 - it may be too restrictive (some setups expect 775 directories).
485 - Fix aclocal to honor definitions located in files which have been
486 m4_included manually. aclocal 1.8 had been updated to check
487 m4_included files for new requirements, but forgot that these
488 m4_included files can also provide new definitions.
490 Note that if you have such a setup, we recommend you get rid of
491 it. In the past, there was a reason to m4_include files manually:
492 aclocal used to duplicate entire M4 files into aclocal.m4, even
493 files that were distributed. Some packages were therefore
494 m4_including the distributed file directly, and playing some
495 tricks to ensure aclocal would not copy that file to aclocal.m4,
496 in order to limit the amount of duplication. Since aclocal 1.8.x
497 will precisely output m4_includes for local M4 files, we recommend
498 that you clean up your setup, removing all manual m4_includes and
499 letting aclocal output them.
501 - Output detailed menus in the Info version if the Automake manual,
502 so that Emacs can locate the indexes.
504 - configure.ac and configure were listed twice in DIST_COMMON (an
505 internal variable where Automake lists configury files to
506 distribute). This was harmless, but unaesthetic.
508 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
509 This was an issue only in the Automake package itself, not in
512 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
513 DEST:SRC. This was wrong, as some packages do
514 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
517 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
518 argument. This caused two kinds of failures:
519 - Rules installing data in a conditionally defined directory
520 failed when that directory was undefined. In this case no
521 argument was supplied.
522 - `make installdirs' failed, because several directories were
523 passed to $(mkdir_p). This was an issue only on platform
524 were $(mkdir_p) is implemented with `install-sh -d'.
525 $(mkdir_p) as been changed to accept 0 or more arguments, as
528 * Long-standing bugs:
530 - Fix an unexpected diagnostic occurring when users attempt
531 to override some internal variables that Automake appends to.
533 - aclocal now scans configure.ac for macro definitions (PR/319).
535 - Fix a portability issue with OSF1/Tru64 Make. If a directory
536 distributes files which are outside itself (this usually occurs
537 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
538 from a parent package), then `make distcheck' fails due to an
539 optimization performed by OSF1/Tru64 Make in its VPATH handling.
540 (tests/subpkg2.test failure)
542 - Fix another portability issue with Sun and OSF1/Tru64 Make.
543 In a VPATH-build configuration, `make install' would install
544 nobase_ files to wrong locations.
546 - Fix a Perl `uninitialized value' diagnostic occurring when
547 automake complains that a Texinfo file does not have a
548 @setfilename statement.
550 - Erase config.status.lineno during `make distclean'. This file
551 can be created by config.status. Automake already knew about
552 configure.lineno, but forgot config.status.lineno.
554 - Distribute all files, even those which are built and installed
555 conditionally. This change affects files listed in conditionally
556 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
557 as well as those listed in conditionally defined dist_*_DATA,
558 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
560 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
561 doesn't conform to POSIX.
563 - Normalize help strings for configure variables and options added
568 - Check for python2.4 in AM_PATH_PYTHON.
570 * Spurious failures in test suite:
572 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
573 tests/ltconv.test: fix failures with CVS Libtool.
574 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
575 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
576 fix failures with old Texinfo versions.
582 - The NEWS file is more verbose.
586 - Autoconf 2.58 or greater is required.
590 - Default source file names in the absence of a _SOURCES declaration
591 are made by removing any target extension before appending `.c', so
592 to make the libtool module `foo.la' from `foo.c', you only need to
595 lib_LTLIBRARIES = foo.la
596 foo_la_LDFLAGS = -module
598 For backward compatibility, foo_la.c will be used instead of
599 foo.c if this file exists or is the explicit target of a rule.
600 However -Wobsolete will warn about this deprecated naming.
602 - AR's `cru' flags are now set in a global ARFLAGS variable instead
603 of being hard-coded in each $(AR) invocation, so they can be
604 substituted from configure.ac. This has been requested by people
605 dealing with non-POSIX ar implementations.
607 - New warning option: -Woverride. This will warn about any user
608 target or variable definitions which override Automake
611 - Texinfo rules back up and restore info files when makeinfo fails.
613 - Texinfo rules now support the `html' target.
614 Running this requires Texinfo 4.0 or greater.
616 `html' is a new recursive target, so if your package mixes
617 hand-crafted `Makefile.in's with Automake-generated
618 `Makefile.in's, you should adjust the former to support (or
619 ignore) this target so that `make html' recurses successfully. If
620 you had a custom `html' rule in your `Makefile.am', it's better to
621 rename it as `html-local', otherwise your rule will override
622 Automake's new rule (you can check that by running `automake
623 -Woverride') and that will stop the recursion to subdirectories.
625 Last but not least, this `html' rule is declared PHONY, even when
626 overridden. Fortunately, it appears that few packages use a
627 non-PHONY `html' rule.
629 - Any file which is m4_included from configure.ac will appear as a
630 configure and Makefile.in dependency, and will be automatically
633 - The rules for rebuilding Makefiles and Makefile.ins will now
634 rebuild all Makefiles and all Makefile.ins at once when one of
635 configure's dependencies has changed. This is considerably faster
636 than previous implementations, where config.status and automake
637 were run separately in each directory (this still happens when you
638 change a Makefile.am locally, without touching configure.ac or
639 friends). Doing this also solves a longstanding issue: these
640 rebuild rules failed to work when adding new directories to the
641 tree, forcing you to run automake manually.
643 - For similar reasons, the rules to rebuild configure,
644 config.status, and aclocal.m4 are now defined in all directories.
645 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
646 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
647 should better define them in all directories. This is easily done
648 using an AC_SUBST (make sure you prefix these dependencies with
649 $(top_srcdir) since this variable will appear at different
650 levels of the build tree).
652 - aclocal will now use `m4_include' instead of copying local m4
653 files into aclocal.m4. (Local m4 files are those you ship with
654 your project, other files will be copied as usual.)
656 Because m4_included files are automatically distributed, it means
657 for most projects there is no point in EXTRA_DISTing the list of
658 m4 files which are used. (You can probably get rid of
659 m4/Makefile.am if you had one.)
661 - aclocal will avoid touching aclocal.m4 when possible, so that
662 Autom4te's cache isn't needlessly invalidated. This behavior can
663 be switched off with the new `--force' option.
665 - aclocal now uses Autoconf's --trace to detect macros which are
666 actually used and will no longer include unused macros simply
667 because they where mentioned. This was often the case for macros
668 called conditionally.
670 - New options no-dist and no-dist-gzip.
672 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
673 py-compile, and ylwrap, now all understand --version and --help.
675 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
676 links as part of the distclean target and including source files in
679 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
680 argument. The latter can be used to override the default behavior
683 - Automake will exit with $? = 63 on version mismatch. (So does
684 Autoconf 2.58) missing knows this, and in this case it will
685 emulate the tools as if they were absent. Because older versions
686 of Automake and Autoconf did not use this exit code, this change
687 will only be useful in projects generated with future versions of
690 - When using AC_CONFIG_FILES with multiple input files, Automake
691 generates the first ".in" input file for which a ".am" exists.
692 (Former versions would try to use only the first input file.)
694 - lisp_DATA is now allowed. If you are using the empty ELCFILES
695 idiom to disable byte-compilation of lisp_LISP files, it is
696 recommended that you switch to using lisp_DATA. Note that
697 this is not strictly equivalent: lisp_DATA will install elisp
698 files even if emacs is not installed, while *_LISP do not
699 install anything unless emacs is found.
701 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
702 available. This selection is achieved through the Makefile
703 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
704 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
705 `$(install_sh) -m 0755 -d'.
709 - Because `mkdir -p' is available on most platforms, and we can use
710 `install-sh -d' when it is not, the use of the mkinstalldirs
711 script is being phased out. `automake --add-missing' no longer
712 installs it, and if you remove mkinstalldirs from your package,
713 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
715 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
716 gettextize and autopoint will install it when needed. Automake
717 will continue to define the $(mkinstalldirs) and to distribute
718 mkinstalldirs when this script is in the source tree.
720 - AM_PROG_CC_STDC is now empty. The content of this macro was
721 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
722 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
723 renaming should be safe, even if you have to support several,
724 versions of Automake, because AC_PROG_CC defines this variable
725 since Autoconf 2.54.)
727 - Some users where using the undocumented ACLOCAL_M4_SOURCES
728 variable to override the aclocal.m4 dependencies computed
729 (inaccurately) by older versions of Automake. Because Automake
730 now tracks configure's m4 dependencies accurately (see m4_include
731 above), the use of ACLOCAL_M4_SOURCES should be considered
732 obsolete and will be flagged as such when running `automake
737 - Defining programs conditionally using Automake conditionals no
738 longer leads to a combinatorial explosion. The following
739 construct used to be troublesome when used with dozens of
754 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
756 - Due to implementation constraints, previous versions of Automake
757 proscribed multiple conditional definitions of some variables
767 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
768 This restriction has been lifted, and these variables now
769 support multiple conditional definitions as do other variables.
771 - Cleanup the definitions of $(distdir) and $(top_distdir).
772 $(top_distdir) now points to the root of the distribution
773 directory created during `make dist', as it did in Automake 1.4,
774 not to the root of the build tree as it did in intervening
775 versions. Furthermore these two variables are now only defined in
776 the top level Makefile, and passed to sub-directories when running
779 - The --no-force option now correctly checks the Makefile.in's
780 dependencies before deciding not to update it.
782 - Do not assume that make files are called Makefile in cleaning rules.
784 - Update .info files in the source tree, not in the build tree. This
785 is what the GNU Coding Standard recommend. Only Automake 1.7.x
786 used to update these files in the build tree (previous versions did
787 it in the source tree too), and it caused several problems, varying
788 from mere annoyance to portability issues.
790 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
791 when --add-missing and --force-missing are used. For backward
792 compatibility --add-missing will continue to install COPYING (in
793 `gnu' strictness) when none of these three files exist, but this
794 use is deprecated: you should better choose a license yourself and
795 install it once for all in your source tree (and in your code
798 - Fix ylwrap so that it does not overwrite header files that haven't
799 changed, as the inline rule already does.
801 - User-defined rules override automake-defined rules for the same
802 targets, even when rules do not have commands. This is not new
803 (and was documented), however some of the automake-generated
804 rules have escaped this principle in former Automake versions.
805 Rules for the following targets are affected by this fix:
807 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
808 info, info-am, install-data-am, install-exec-am, install-info,
809 install-info-am, install-man, installcheck-am, maintainer-clean,
810 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
811 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
813 Practically it means that an attempt to supplement the dependencies
814 of some target, as in
818 will now *silently override* the automake definition of the
819 rule for this target. Running `automake -Woverride' will diagnose
820 all such overriding definitions.
822 It should be noted that almost all these targets support a *-local
823 variant that is meant to supplement the automake-defined rule
824 (See node `Extending' in the manual). The above rule should
827 clean-local: my-clean-rule
829 These *-local targets have been documented since at least
830 Automake 1.2, so you should not fear the change if you have
831 to support multiple automake versions.
835 - The Automake manual is now distributed under the terms of the GNU FDL.
837 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
839 - core dumps are no longer removed by the cleaning rules. There are
840 at least three reasons for this:
841 1. These files should not be created by any build step,
842 so their removal do not fit any of the cleaning rules.
843 Actually, they may be precious to the developer.
844 2. If such file is created during a build, then it's clearly a
845 bug Automake should not hide. Not removing the file will
846 cause `make distcheck' to complain about its presence.
847 3. Operating systems have different naming conventions for
848 core dump files. A core file on one system might be a
849 completely legitimate data file on another system.
851 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
852 defined by Automake. This means that any definition in the
853 environment will be used, unless overridden in the Makefile.am or
854 on the command line. The old behavior, where these variables were
855 defined empty in each Makefile, can be obtained by AC_SUBSTing or
856 AC_ARG_VARing each variable from configure.ac.
858 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
859 documented. (The is not a new feature, these variables have
860 been there since at least Automake 1.4.)
863 * Fix install-strip to work with nobase_ binaries.
864 * Fix renaming of #line directives in ylwrap.
865 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
868 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
869 * Fix detection of Debian's install-info, broken since version 1.5.
870 (Debian bug #213524).
871 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
872 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
875 * The implementation of automake's --no-force option is unreliable,
876 so this option is ignored in this version. A real fix will appear in
877 Automake 1.8. (Debian Bug #206299)
878 * AM_PATH_PYTHON: really check the whole list of interpreters if no
879 argument is given. (PR/399)
880 * Do not warn about leading `_' in variable names, even with -Wportability.
881 * Support user redefinitions of TEXINFO_TEX.
882 * depcomp: support AIX Compiler version 6.
883 * Fix missing rebuilds during `make dist' with BSD make.
884 (Could produce tarballs containing out-of-date files.)
885 * Resurrect multilib support.
886 * Noteworthy manual updates:
887 - Extending aclocal: how to write m4 macros that won't trigger warnings
889 - A Shared Library: Rewrite and split into subsections.
892 * Fix depcomp's icc mode for ICC 7.1.
893 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
894 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
895 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
896 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
897 * Remove Latin-1 characters from elisp-comp.
898 * Update the manual's @dircategory to match the Free Software Directory.
901 * Update install-sh's license to remove an advertising clause.
903 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
904 that caused invalid Makefile.ins to be generated.
905 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
906 * New FAQ entry: renamed objects.
909 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
910 the Emacs implementation)
911 * Fix output of aclocal.m4 dependencies in subdirectories.
912 * Use `mv -f' instead of `mv' in fastdep rules.
913 * Upgrade mdate-sh to work on OS/2.
914 * Don't byte-compile elisp files when ELCFILES is set empty.
915 (this documented feature was broken by 1.7.3)
916 * Diagnose trailing backslashes on last line of Makefile.am.
917 * Diagnose whitespace following trailing backslashes.
918 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
919 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
921 * `make install' will build `BUILT_SOURCES' first.
922 * Minor documentation fixes.
925 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
926 * Query distutils for `pythondir' and `pythonexecdir', instead of
927 using an hardcoded path. This should allow builds on 64-bit
928 distributions that usually use lib64/ instead of lib/.
929 * AM_PATH_PYTHON will also search for python2.3.
930 * elisp files are now built all at once instead of one by one. Besides
931 incurring a speed-up, this is required to support interdependent elisp files.
933 - `make distcheck' will now work in `_inst/' and `_build' instead
934 of `=inst/' and `=build/'
935 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
936 - install/uninstall `*.i[0-9][0-9]'-style info files
937 - more changes that affect only the Automake package (not its output)
938 * Fix some incompatibilities with upcoming perl-5.10.
939 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
942 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
943 is troublesome with gcc and Solaris compilers. (PR/385)
944 - makedepend mode: work with Libtool. (PR/385 too)
946 * better support for unusual gettext setups, such as multiple po/ directories
948 - Flag missing po/ and intl/ directories as warnings, not errors.
949 - Disable these warnings if po/ does not exist.
950 * Noteworthy manual updates:
952 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
954 - Document `AM_YFLAGS = -d'. (PR/382)
957 * Fix installation and uninstallation of Info files built in subdirectories.
958 * Do not run `./configure --with-included-gettext' during `make distcheck'
959 if AM_GNU_GETTEXT([external]) is used.
960 * Correctly uninstall renamed man pages.
961 * Do not strip escaped newline in variables defined in one condition
962 and augmented in another condition.
963 * Fix ansi2knr rules for LIBOBJS sources.
964 * Clean all known Texinfo index files, not only those which appear to
965 be used, because we cannot know wich indexes are used in included files.
966 (PR/375, Debian Bug #168671)
967 * Honor only the first @setfilename seen in a Texinfo file.
968 * Treat "required file X not found" diagnostics as errors (exit status 1).
969 * Don't complain that a required file is not found when it is a Makefile
971 * Don't use single suffix inference rules when building `.info'-less
972 Info files, for the sake of Solaris make.
973 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
974 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
975 * Warn about multiple inference rules when -Wportability is used. (PR/372)
976 * Fix building of deansified files from subdirectories. (PR/370)
977 * Add missing `fi' in the .c->.obj rules.
978 * Improve install-sh to work even when names contain spaces or certain
979 (but not all) shell metachars.
980 * Fix the following spurious failures in the test suite:
981 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
982 * Noteworthy manual updates:
983 - Augment the section about BUILT_SOURCES.
984 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
987 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
989 * Aclocal should now recognize macro names containing parentheses, e.g.
990 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
991 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
993 * Install Python files even if they were built. (PR/369)
994 * Have stamp-vti dependent upon configure instead of configure.ac, as the
995 version might not be defined in the latter. (PR/358)
996 * Reorder arguments passed to a couple of commands, so things works
997 when POSIXLY_CORRECT=1.
998 * Fix a regex that can cause Perl to segfault on large input.
1000 * Fix distribution of packages that have some sources defined conditionally,
1001 as in the `Conditional compilation using Automake conditionals' example
1003 * Fix spurious test suite failures on IRIX.
1004 * Don't report a required variable as undefined if it has been
1005 defined conditionally for the "right" conditions.
1006 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1007 `make distcheck' fails.
1008 * Fix distribution of included Makefile fragment, so we don't create
1009 spurious directories in the distribution. (PR/366)
1010 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1013 * Autoconf 2.54 is required.
1014 * `aclocal' and `automake' will no longer warn about obsolete
1015 configure macros. This is done by `autoconf -Wobsolete'.
1016 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1017 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1018 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1019 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1020 `configure.ac' for you.
1021 * Support for per-program and per-library `_CPPFLAGS'.
1022 * New `ctags' target (builds CTAGS files).
1023 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1024 (see `automake --help' or the manual for a list of them).
1025 * Honor the WARNINGS environment variable.
1026 * Omit the call to depcomp when using gcc3: call the compiler directly.
1027 * A new option, std-options, tests that programs support --help and --version
1028 when `make installcheck' is run. This is enabled by --gnits.
1029 * Texinfo rules now support the `ps' and `pdf' targets.
1030 * Info files are now created in the build directory, not the source directory.
1031 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1033 * `make distcheck' will enforce DESTDIR support by attempting
1035 * `+=' can be used in conditionals, even if the augmented variable
1036 was defined for another condition.
1037 * Makefile fragments (inserted with `include') are always distributed.
1038 * Use Autoconf's --trace interface to inspect configure.ac and get
1039 a more accurate view of it.
1040 * Add support for extending aclocal's default macro search path
1041 using a `dirlist' file within the aclocal directory.
1042 * automake --output-dir is deprecated.
1043 * The part of the distcheck target that checks whether uninstall actually
1044 removes all installed files has been moved in a separate target,
1045 distuninstallcheck, so it can be overridden easily.
1049 * Support for AM_INIT_GETTEXT([external])
1050 * Bug fixes, including:
1051 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1052 - nobase_ programs and scripts honor --program-transform correctly.
1053 - Erase configure.lineno during `make distclean'.
1054 - Erase YACC and LEX outputs during `make maintainer-clean'.
1057 * Many bug fixes, including:
1058 - Requiring the current version works.
1059 - Fix "$@" portability issues (for Zsh).
1060 - Fix output of dummy dependency files in presence of post-processed
1062 - Don't compute dependencies in background to avoid races with libtool.
1063 - Fix handling of _OBJECTS variables for targets sharing source variables.
1064 - Check dependency mode for Java when AM_PROG_GCJ is used.
1067 * automake --output-dir is deprecated
1068 * Many bug fixes, including:
1069 - Don't choke on AM_LDFLAGS definitions.
1070 - Clean libtool objects from subdirectories.
1071 - Allow configure variables with reserved suffix and unknown prefix
1072 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1073 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1076 * Autoconf 2.52 is required.
1077 * automake no longer run libtoolize.
1078 This is the job of autoreconf (from GNU Autoconf).
1079 * `dist' generates all the archive flavors, as did `dist-all'.
1080 * `dist-gzip' generates the Gzip tar file only.
1081 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1082 explosion. Makefile.in's keep a reasonable size.
1083 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1084 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1086 * `#line' of Lex and Yacc files are properly set.
1087 * EXTRA_DIST can contain generated directories.
1088 * Support for dot-less extensions in suffix rules.
1089 * The part of the distcheck target that checks whether distclean actually
1090 cleans all built files has been moved in a separate target, distcleancheck,
1091 so it can be overridden easily.
1092 * `make distcheck' will pass additional options defined in
1093 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1094 * Fixed CDPATH portability problems, in particular for MacOS X.
1095 * Fixed handling of nobase_ targets.
1096 * Fixed support of implicit rules leading to .lo objects.
1097 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1098 * Added uninstall-hook target
1099 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1100 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1101 (Note that "pkgname" is not "tarname", see the manual for details.)
1102 It is also possible to pass a list of global Automake options as
1103 first argument to this new form of AM_INIT_AUTOMAKE.
1104 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1105 to be a real assembler.
1106 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1107 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1108 * aclocal and automake are also installed with the version number
1109 appended, and some of the install directory names have changed.
1110 This lets you have multiple versions installed simultaneously.
1111 * Support for parsers and lexers in subdirectories.
1114 * Support for `configure.ac'.
1115 * Support for `else COND', `endif COND' and negated conditions `!COND'.
1116 * `make dist-all' is much faster.
1117 * Allows '@' AC_SUBSTs in macro names.
1118 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
1119 * User-side dependency tracking. Developers no longer need GNU make
1121 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
1122 * Most files are correctly handled if they appear in subdirs
1123 For instance, a _DATA file can appear in a subdir
1124 * GNU tar is no longer required for `make dist'
1125 * Added support for `dist_' and `nodist_' prefixes
1126 * Added support for `nobase_' prefix

1128 * Support for per-executable and per-library compilation flags
1132 * Added support for the Fortran 77 programming language.
1133 * Re-indexed the Automake Texinfo manual.
1134 * Added `AM_FOOFLAGS' variable for each compiler invocation;
1135 e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags
1136 * Support for latest autoconf, including support for objext
1137 * Can now put `.' in SUBDIRS to control build order
1138 * `include' command and `+=' support for macro assignment
1139 * Dependency tracking no long susceptible to deleted header file problem
1140 * Maintainer mode now a conditional. @MAINT@ is now an anachronism.
1145 * Better Cygwin32 support
1146 * Support for suffix rules with _SOURCES variables
1147 * New options `readme-alpha' and `check-news'; Gnits mode sets these
1148 * @LEXLIB@ no longer required when lex source seen
1149 Lex support in `missing', and new lex macro. Update your missing script.
1150 * Built-in support for assembly
1151 * aclocal gives error if `AM_' macro not found
1152 * Passed YFLAGS, not YACCFLAGS, to yacc
1153 * AM_PROG_CC_STDC does not have to come before AC_PROG_CPP
1154 * Dependencies computed as a side effect of compilation
1155 * Preliminary support for Java

1161 * Better DejaGnu support
1162 * Added no-installinfo option
1163 * Added Emacs Lisp support
1164 * Added --no-force option
1165 * Included `aclocal' program
1166 * Automake will now generate rules to regenerate aclocal.m4, if appropriate
1167 * Now uses `AM_' macro names everywhere
1168 * ansi2knr option can have directory prefix (eg `../lib/ansi2knr')
1169 ansi2knr now works correctly on K&R sources
1170 * Better C++, yacc, lex support
1171 * Will compute _DEPENDENCIES variables automatically if not supplied
1172 * Will interpolate $(...) and ${...} when examining contents of a variable
1173 * .deps files now in build directory, not source directory; dependency
1174 handling generally rewritten
1175 * DATA, MANS and BUILT_SOURCES no longer included in distribution
1176 * can now put config.h into a subdir
1177 * Added dist-all target
1178 * Support for install-info program (see texinfo 3.9)
1179 * Support for "yacc -d"
1180 * configure substitutions are automatically discovered and included
1181 in generated Makefile.in
1182 * Special --cygnus mode
1183 * OMIT_DEPENDENCIES can now hold list of dependencies to be omitted
1184 when making distribution. Some dependencies are auto-ignored.
1185 * Changed how libraries are specified in _LIBRARIES variable
1186 * Full libtool support, from Gord Matzigkeit
1187 * No longer have to explicitly touch stamp-h when using AC_CONFIG_HEADER;
1188 AM_CONFIG_HEADER handles it automatically
1189 * Texinfo output files no longer need .info extension
1190 * Added `missing' support
1192 * Conditionals in Makefile.am, from Ian Taylor
1196 * distcheck target runs install and installcheck targets
1197 * Added preliminary support for DejaGnu.
1202 * More libtool fixes from Gord Matzigkeit; libtool support is still

1206 * New "distcheck" target
1210 * mkinstalldirs and mdate-sh now appear in directory specified by
1212 * Removed DIST_SUBDIRS, DIST_OTHER
1213 * AC_ARG_PROGRAM only required when an actual program exists
1214 * dist-hook target now run before distribution packaged up; idea from

1217 * Added short option names.
1218 * Better "dist" support when gluing together multiple packages
