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
26 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
27 config.lt is removed correctly now.
31 - subdir-object mode works now with Fortran (F77, FC, preprocessed
34 - For files with extension .f90, .f95, .f03, or .f08, the flag
35 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
37 - Files with extension .sx are also treated as preprocessed assembler.
39 - Python 3.0 is supported now, Python releases prior to 2.0 are no
42 - The default source file extension (.c) can be overridden with
43 AM_DEFAULT_SOURCE_EXT now.
45 * Miscellaneous changes:
47 - Automake development is done in a git repository on Savannah now, see
49 http://git.sv.gnu.org/gitweb/?p=automake.git
51 A read-only CVS mirror is provided at
53 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
54 checkout -d automake HEAD
56 - "make dist" can now create xz-compressed tarballs,
57 as well as (deprecated?) lzma-compressed tarballs.
59 - Automake is licensed under GPLv3+. `automake --add-missing' will
60 by default install the GPLv3 file as COPYING if it is missing.
61 It will also warn that the license file should be added to source
62 control. Note that Automake will never overwrite an existing COPYING
63 file, even when the `--force-missing' option is used.
65 - The manual is now distributed under the terms of the GNU FDL 1.3.
67 - Automake ships and installs man pages for automake and aclocal now.
69 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
71 - install-sh supports -C, which does not update the installed file
72 (and its time stamps) if the contents did not change.
74 - The targets `install' and `uninstall' are more efficient now, in that
75 for example multiple files from one Automake variable such as
76 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
77 invocation if they do not have to be renamed.
79 Both install and uninstall may sometimes enter (`cd' into) the target
80 installation directory now, when no build-local scripts are used.
82 For built-in rules, `make install' now fails reliably if installation
83 of a file failed. Conversely, `make uninstall' even succeeds when
84 issued multiple times.
86 These changes may need some adjustments from users: For example,
87 some `install' programs refuse to install multiple copies of the
88 same file in one invocation, so you may need to remove duplicate
89 entries from file lists.
91 Also, within one set of files, say, nobase_data_DATA, the order of
92 installation may be changed, or even unstable among different hosts,
93 due to the use of associative arrays in awk. The increased use of
94 awk matches a similar move in Autoconf to provide for better scaling.
96 Further, most undocumented per-rule install command variables such as
97 binSCRIPT_INSTALL have been removed because they are not needed any
98 more. Packages which use them should be using the appropriate one of
99 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
100 counterpart, depending on the type of files and the need for automatic
101 target directory creation.
103 - The "deleted header file problem" for *.m4 files is avoided by
104 stub rules. This allows `make' to trigger a rerun of `aclocal'
105 also if some previously needed macro file has been removed.
107 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
108 an otherwise up to date tree.
110 - The `color-tests' option causes colored test result output on terminals.
112 - New prefix `notrans_' for manpages which should not be transformed
113 by --program-transform.
115 - New macro AM_COND_IF for conditional evaluation and conditional
118 - For AC_CONFIG_LINKS, if source and destination are equal, do not
119 remove the file in a non-VPATH build. Such setups work with Autoconf
122 - AM_MAINTAINER_MODE now allows for an optional argument specifying
125 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
126 useful especially for multi-line values.
128 - The `missing' script works better with versioned tool names.
130 - Automake's early configure-time sanity check now diagnoses an
131 unsafe absolute source directory name and makes configure fail.
133 - The Automake macros and rules cope better with whitespace in the
134 current directory name, as long as the relative path to `configure'
135 does not contain whitespace. To this end, the values of `$(MISSING)'
136 and `$(install_sh)' may contain suitable quoting, and their expansion
137 might need `eval'uation if used outside of a makefile. These
138 undocumented variables may be used in several documented macros such
139 as $(AUTOCONF) or $(MAKEINFO).
143 * Long standing bugs:
145 - Fix aix dependency tracking for libtool objects.
147 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
148 unnecessary use of the `compile' script.
150 - For nobase_*_LTLIBRARIES with nonempty directory components, the
151 correct `-rpath' argument is used now.
153 - `config.status --file=Makefile depfiles' now also works with the
154 extra quoting used internally by Autoconf 2.62 and newer
155 (it used to work only without the `--file=' bit).
157 * Bugs introduced by 1.10:
159 - Fix output of dummy dependency files in presence of post-processed
160 Makefile.in's again, but also cope with long lines.
162 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
163 that have been declared as programs in the same Makefile.
164 This is for consistency with the analogous change to TESTS in 1.10.
166 - Fix order of standard includes to again be `-I. -I$(srcdir)',
167 followed by directories containing config headers.
171 * Version requirements:
173 - Autoconf 2.60 or greater is required.
175 - Perl 5.6 or greater is required.
177 * Changes to aclocal:
179 - aclocal now also supports -Wmumble and -Wno-mumble options.
181 - `dirlist' entries (for the aclocal search path) may use shell
182 wildcards such as `*', `?', or `[...]'.
184 - aclocal supports an --install option that will cause system-wide
185 third-party macros to be installed in the local directory
186 specified with the first -I flag. This option also uses #serial
187 lines in M4 files to upgrade local macros.
189 The new aclocal options --dry-run and --diff help to review changes
190 before they are installed.
192 - aclocal now outputs an autoconf version check in aclocal.m4 in
193 projects using automake.
195 For a few years, automake and aclocal have been calling autoconf
196 (or its underlying engine autom4te) to accurately retrieve the
197 data they need from configure.ac and its siblings. Doing so can
198 only work if all autotools use the same version of autoconf. For
199 instance a Makefile.in generated by automake for one version of
200 autoconf may stop working if configure is regenerated with another
201 version of autoconf, and vice versa.
203 This new version check ensures that the whole build system has
204 been generated using the same autoconf version.
206 * Support for new Autoconf macros:
208 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
210 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
211 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
212 in different directories. However, only one instance of such a
213 library objects directory is supported.
215 * Change to Libtool support:
217 - Libtool generic flags (those that go before the --mode=MODE option)
218 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
220 * Yacc and Lex changes:
222 - The rebuild rules for distributed Yacc and Lex output will avoid
223 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
226 - ylwrap is now always used for lex and yacc source files,
227 regardless of whether there is more than one source per directory.
231 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
232 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
233 tracking, unlike non-preprocessed assembler (*.s).
235 - subdir-object mode works now with Assembler. Automake assumes
236 that the compiler understands `-c -o'.
238 - Preprocessed assembler (*.S) compilation now also honors
239 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
241 - Improved support for Objective C:
242 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
243 - A new section of the manual documents the support.
245 - New support for Unified Parallel C:
246 - AM_PROG_UPC looks for a UPC compiler.
247 - A new section of the manual documents the support.
249 - Per-target flags are now correctly handled in link rules.
251 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
252 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
253 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
254 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
256 The fix for compiler flags (i.e., using maude_CFLAGS instead of
257 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
258 is expected to work (and actually works during compilation).
260 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
261 "in addition to" breaks backward compatibility with older versions.
262 If your package used both variables, as in
264 AM_LDFLAGS = common flags
266 a_LDFLAGS = more flags
269 and assumed *_LDFLAGS would sum up, you should rewrite it as
271 AM_LDFLAGS = common flags
273 a_LDFLAGS = $(AM_LDFLAGS) more flags
276 This new behavior of *_LDFLAGS is more coherent with other
277 per-target variables, and the way *_LDFLAGS variables were
278 considered internally.
280 * New installation targets:
282 - New targets mandated by GNU Coding Standards:
287 By default they will only install Texinfo manuals.
288 You can customize them with *-local variants:
294 - The undocumented recursive target `uninstall-info' no longer exists.
295 (`uninstall' is in charge of removing all possible documentation
296 flavors, including optional formats such as dvi, ps, or info even
297 when `no-installinfo' is used.)
299 * Miscellaneous changes:
301 - Automake no longer complains if input files for AC_CONFIG_FILES
302 are specified using shell variables.
304 - clean, distribution, or rebuild rules are normally disabled for
305 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
306 AC_CONFIG_LINK specified using shell variables. However, if these
307 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
308 be able to output rules anyway.
309 (See the Automake documentation for AC_CONFIG_FILES.)
311 - $(EXEEXT) is automatically appended to filenames of TESTS
312 that have been declared as programs in the same Makefile.
313 This is mostly useful when some check_PROGRAMS are listed in TESTS.
315 - `-Wportability' has finally been turned on by default for `gnu' and
316 `gnits' strictness. This means, automake will complain about %-rules
317 or $(GNU Make functions) unless you switch to `foreign' strictness or
318 use `-Wno-portability'.
320 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
321 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
322 $(mkdir_p) variable is still defined (to the same value as
323 $(MKDIR_P)) but should be considered obsolete. If you are using
324 $(mkdir_p) in some of your rules, please plan to update them to
325 $(MKDIR_P) at some point.
327 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
328 They still work in this release, but may be withdrawn in a future one.
330 - Inline compilation rules for gcc3-style dependency tracking are
333 - Automake installs a "Hello World!" example package in $(docdir).
334 This example is used throughout the new "Autotools Introduction"
335 chapter of the manual.
339 * Makefile.in bloat reduction:
341 - Inference rules are used to compile sources in subdirectories when
342 the `subdir-objects' option is used and no per-target flags are
343 used. This should reduce the size of some projects a lot, because
344 Automake used to output an explicit rule for each such object in
347 - Automake no longer outputs three rules (.o, .obj, .lo) for each
348 object that must be built with explicit rules. It just outputs
349 the rules required to build the kind of object considered: either
350 the two .o and .obj rules for usual objects, or the .lo rule for
353 * Change to Libtool support:
355 - Libtool tags are used with libtool versions that support them.
356 (I.e., with Libtool 1.5 or greater.)
358 - Automake is now able to handle setups where a libtool library is
359 conditionally installed in different directories, as in
362 lib_LTLIBRARIES = liba.la
364 pkglib_LTLIBRARIES = liba.la
366 liba_la_SOURCES = ...
368 * Changes to aclocal:
370 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
371 really evaluated, before it decides to include them in aclocal.m4.
372 This solves nasty problems with conditional redefinitions of
373 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
374 *.m4 files to be included in any project using these macros.
375 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
376 most famous instance of this bug.)
378 - Do not complain about missing conditionally AC_REQUIREd macros
379 that are not actually used. In 1.8.x aclocal would correctly
380 determine which of these macros were really needed (and include
381 only these in the package); unfortunately it would also require
382 all of them to be present in order to run. This created
383 situations were aclocal would not work on a tarball distributing
384 all the macros it uses. For instance running aclocal on a project
385 containing only the subset of the Gettext macros in use by the
386 project did not work, because gettext conditionally requires other
389 * Portability improvements:
391 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
392 tar-pax. The new option filename-length-max=99 helps diagnosing
393 filenames that are too long for tar-v7. (PR/414)
395 - Variables aumented with `+=' are now automatically flattened (i.e.,
396 trailing backslashes removed) and then wrapped around 80 colummns
397 (adding trailing backslashes). In previous versions, a long series
403 would result in a single-line definition of VAR that could possibly
404 exceed the maximum line length of some make implementations.
406 Non-augmented variables are still output as they are defined in
411 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
412 Works the same as the old Fortran 77 implementation; just replace
413 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
414 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
416 - Support for conditional _LISP.
418 - Support for conditional -hook and -local rules (PR/428).
420 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
422 - Automake will not write any Makefile.ins after the first error it
423 encounters. The previous Makefile.ins (if any) will be left in
424 place. (Warnings will not prevent output, but remember they can
425 be turned into errors with -Werror.)
427 - The restriction that SUBDIRS must contain direct children is gone.
430 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
431 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
435 * Long standing bugs:
437 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
438 so that `make distclean' and `make maintainer-clean' can work.
440 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
442 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
444 - Polish diagnostic when no input file is found.
448 * Long standing bugs:
450 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
451 overridden by the user.
453 - Honor PATH_SEPARATOR in various places of the Automake package, for
456 - Adjust dependency tracking mode detection to ICC 8.0's new output.
459 - Fix install-sh so it can install the `mv' binary... using `mv'.
461 - Fix tru64 dependency tracking for libtool objects.
463 - Work around Exuberant Ctags when creating a TAGS files in a directory
464 without files to scan but with subdirectories to include.
466 * Bugs introduced by 1.8:
468 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
469 not defined in the same conditions as the _LDADD that uses it.
471 - Do not warn when JAVAROOT is overridden, this is legitimate.
475 * Long standing bugs:
477 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
478 or any of the other *dir variables contain a space.
480 Please note that Automake does not and cannot support spaces in
481 filenames that are involved during the build. This change affects
482 only installation paths, so that `make install' does not bomb out
483 in packages configured with
484 ./configure --prefix '/c/Program Files'
486 - Fix the depfiles output so it works with GNU sed (<4.1) even when
487 POSIXLY_CORRECT is set.
489 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
490 since Autoconf 2.54, which defines LIBOBJS itself.
492 - Fix a potential (but unlikely) race condition in parallel elisp
493 builds. (Introduced in 1.7.3.)
495 - Do not assume that users override _DEPENDENCIES in all conditions
496 where Automake will try to define them.
498 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
499 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
502 This fix also affects the $(mkdir_p) variable defined since
503 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
504 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
506 - Secure temporary directory creation in `make distcheck'. (PR/413)
508 - Do not generate two build rules for `parser.h' when the
509 parser appears in two different conditionals.
511 - Work around a Solaris 8 /bin/sh bug in the test for dependency
512 checking. Usually ./configure will not pick this shell; so this
513 fix only helps cases where the shell is forced to /bin/sh.
515 * Bugs introduced by 1.8:
517 - In some situations (hand-written `m4_include's), aclocal would
518 call the `File::Spec->rel2abs' method, which was only introduced
519 in Perl 5.6. This new version reestablish support Perl 5.005.
521 It is likely that the next major Automake releases will require at
522 least Perl 5.6. Consider upgrading your development environment
523 if you are still using the five-year-old Perl 5.005.
525 - Automake would sometimes fail to define rules for targets listed
526 in variables defined in multiple conditions. For instance on
532 it would define only the `a.$(OBJEXT): a.c' rule and omit the
533 `b.$(OBJEXT): b.c' rule.
535 * New sections in manual:
537 - Third-Party Makefiles: how to interface third party Makefiles.
538 - Upgrading: upgrading packages to newer Automake versions.
539 - Multiple Outputs: handling tools that produce many outputs.
543 * A (well known) portability bug slipped in the changes made to
544 install-sh in Automake 1.8.1. The broken install-sh would refuse to
545 install anything on Tru64.
547 * Fix install rules for conditionally built python files. (This never
552 * Bugs introduced by 1.8:
554 - Fix Config.pm import error with old Perl versions (at least
555 5.005_03). One symptom is that aclocal could not find its macro
558 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
559 created by `make install' are always world readable, even if the
560 installer happens to have an overly restrictive umask (e.g. 077).
561 This was a mistake and has been reverted. There are at least two
562 reasons why we must not use `-m 0755':
563 - it causes special bits like SGID to be ignored,
564 - it may be too restrictive (some setups expect 775 directories).
566 - Fix aclocal to honor definitions located in files which have been
567 m4_included manually. aclocal 1.8 had been updated to check
568 m4_included files for new requirements, but forgot that these
569 m4_included files can also provide new definitions.
571 Note that if you have such a setup, we recommend you get rid of
572 it. In the past, there was a reason to m4_include files manually:
573 aclocal used to duplicate entire M4 files into aclocal.m4, even
574 files that were distributed. Some packages were therefore
575 m4_including the distributed file directly, and playing some
576 tricks to ensure aclocal would not copy that file to aclocal.m4,
577 in order to limit the amount of duplication. Since aclocal 1.8.x
578 will precisely output m4_includes for local M4 files, we recommend
579 that you clean up your setup, removing all manual m4_includes and
580 letting aclocal output them.
582 - Output detailed menus in the Info version if the Automake manual,
583 so that Emacs can locate the indexes.
585 - configure.ac and configure were listed twice in DIST_COMMON (an
586 internal variable where Automake lists configury files to
587 distribute). This was harmless, but unaesthetic.
589 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
590 This was an issue only in the Automake package itself, not in
593 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
594 DEST:SRC. This was wrong, as some packages do
595 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
598 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
599 argument. This caused two kinds of failures:
600 - Rules installing data in a conditionally defined directory
601 failed when that directory was undefined. In this case no
602 argument was supplied.
603 - `make installdirs' failed, because several directories were
604 passed to $(mkdir_p). This was an issue only on platform
605 were $(mkdir_p) is implemented with `install-sh -d'.
606 $(mkdir_p) as been changed to accept 0 or more arguments, as
609 * Long-standing bugs:
611 - Fix an unexpected diagnostic occurring when users attempt
612 to override some internal variables that Automake appends to.
614 - aclocal now scans configure.ac for macro definitions (PR/319).
616 - Fix a portability issue with OSF1/Tru64 Make. If a directory
617 distributes files which are outside itself (this usually occurs
618 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
619 from a parent package), then `make distcheck' fails due to an
620 optimization performed by OSF1/Tru64 Make in its VPATH handling.
621 (tests/subpkg2.test failure)
623 - Fix another portability issue with Sun and OSF1/Tru64 Make.
624 In a VPATH-build configuration, `make install' would install
625 nobase_ files to wrong locations.
627 - Fix a Perl `uninitialized value' diagnostic occurring when
628 automake complains that a Texinfo file does not have a
629 @setfilename statement.
631 - Erase config.status.lineno during `make distclean'. This file
632 can be created by config.status. Automake already knew about
633 configure.lineno, but forgot config.status.lineno.
635 - Distribute all files, even those which are built and installed
636 conditionally. This change affects files listed in conditionally
637 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
638 as well as those listed in conditionally defined dist_*_DATA,
639 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
641 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
642 doesn't conform to POSIX.
644 - Normalize help strings for configure variables and options added
649 - Check for python2.4 in AM_PATH_PYTHON.
651 * Spurious failures in test suite:
653 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
654 tests/ltconv.test: fix failures with CVS Libtool.
655 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
656 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
657 fix failures with old Texinfo versions.
663 - The NEWS file is more verbose.
667 - Autoconf 2.58 or greater is required.
671 - Default source file names in the absence of a _SOURCES declaration
672 are made by removing any target extension before appending `.c', so
673 to make the libtool module `foo.la' from `foo.c', you only need to
676 lib_LTLIBRARIES = foo.la
677 foo_la_LDFLAGS = -module
679 For backward compatibility, foo_la.c will be used instead of
680 foo.c if this file exists or is the explicit target of a rule.
681 However -Wobsolete will warn about this deprecated naming.
683 - AR's `cru' flags are now set in a global ARFLAGS variable instead
684 of being hard-coded in each $(AR) invocation, so they can be
685 substituted from configure.ac. This has been requested by people
686 dealing with non-POSIX ar implementations.
688 - New warning option: -Woverride. This will warn about any user
689 target or variable definitions which override Automake
692 - Texinfo rules back up and restore info files when makeinfo fails.
694 - Texinfo rules now support the `html' target.
695 Running this requires Texinfo 4.0 or greater.
697 `html' is a new recursive target, so if your package mixes
698 hand-crafted `Makefile.in's with Automake-generated
699 `Makefile.in's, you should adjust the former to support (or
700 ignore) this target so that `make html' recurses successfully. If
701 you had a custom `html' rule in your `Makefile.am', it's better to
702 rename it as `html-local', otherwise your rule will override
703 Automake's new rule (you can check that by running `automake
704 -Woverride') and that will stop the recursion to subdirectories.
706 Last but not least, this `html' rule is declared PHONY, even when
707 overridden. Fortunately, it appears that few packages use a
708 non-PHONY `html' rule.
710 - Any file which is m4_included from configure.ac will appear as a
711 configure and Makefile.in dependency, and will be automatically
714 - The rules for rebuilding Makefiles and Makefile.ins will now
715 rebuild all Makefiles and all Makefile.ins at once when one of
716 configure's dependencies has changed. This is considerably faster
717 than previous implementations, where config.status and automake
718 were run separately in each directory (this still happens when you
719 change a Makefile.am locally, without touching configure.ac or
720 friends). Doing this also solves a longstanding issue: these
721 rebuild rules failed to work when adding new directories to the
722 tree, forcing you to run automake manually.
724 - For similar reasons, the rules to rebuild configure,
725 config.status, and aclocal.m4 are now defined in all directories.
726 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
727 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
728 should better define them in all directories. This is easily done
729 using an AC_SUBST (make sure you prefix these dependencies with
730 $(top_srcdir) since this variable will appear at different
731 levels of the build tree).
733 - aclocal will now use `m4_include' instead of copying local m4
734 files into aclocal.m4. (Local m4 files are those you ship with
735 your project, other files will be copied as usual.)
737 Because m4_included files are automatically distributed, it means
738 for most projects there is no point in EXTRA_DISTing the list of
739 m4 files which are used. (You can probably get rid of
740 m4/Makefile.am if you had one.)
742 - aclocal will avoid touching aclocal.m4 when possible, so that
743 Autom4te's cache isn't needlessly invalidated. This behavior can
744 be switched off with the new `--force' option.
746 - aclocal now uses Autoconf's --trace to detect macros which are
747 actually used and will no longer include unused macros simply
748 because they where mentioned. This was often the case for macros
749 called conditionally.
751 - New options no-dist and no-dist-gzip.
753 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
754 py-compile, and ylwrap, now all understand --version and --help.
756 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
757 links as part of the distclean target and including source files in
760 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
761 argument. The latter can be used to override the default behavior
764 - Automake will exit with $? = 63 on version mismatch. (So does
765 Autoconf 2.58) missing knows this, and in this case it will
766 emulate the tools as if they were absent. Because older versions
767 of Automake and Autoconf did not use this exit code, this change
768 will only be useful in projects generated with future versions of
771 - When using AC_CONFIG_FILES with multiple input files, Automake
772 generates the first ".in" input file for which a ".am" exists.
773 (Former versions would try to use only the first input file.)
775 - lisp_DATA is now allowed. If you are using the empty ELCFILES
776 idiom to disable byte-compilation of lisp_LISP files, it is
777 recommended that you switch to using lisp_DATA. Note that
778 this is not strictly equivalent: lisp_DATA will install elisp
779 files even if emacs is not installed, while *_LISP do not
780 install anything unless emacs is found.
782 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
783 available. This selection is achieved through the Makefile
784 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
785 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
786 `$(install_sh) -m 0755 -d'.
790 - Because `mkdir -p' is available on most platforms, and we can use
791 `install-sh -d' when it is not, the use of the mkinstalldirs
792 script is being phased out. `automake --add-missing' no longer
793 installs it, and if you remove mkinstalldirs from your package,
794 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
796 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
797 gettextize and autopoint will install it when needed. Automake
798 will continue to define the $(mkinstalldirs) and to distribute
799 mkinstalldirs when this script is in the source tree.
801 - AM_PROG_CC_STDC is now empty. The content of this macro was
802 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
803 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
804 renaming should be safe, even if you have to support several,
805 versions of Automake, because AC_PROG_CC defines this variable
806 since Autoconf 2.54.)
808 - Some users where using the undocumented ACLOCAL_M4_SOURCES
809 variable to override the aclocal.m4 dependencies computed
810 (inaccurately) by older versions of Automake. Because Automake
811 now tracks configure's m4 dependencies accurately (see m4_include
812 above), the use of ACLOCAL_M4_SOURCES should be considered
813 obsolete and will be flagged as such when running `automake
818 - Defining programs conditionally using Automake conditionals no
819 longer leads to a combinatorial explosion. The following
820 construct used to be troublesome when used with dozens of
835 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
837 - Due to implementation constraints, previous versions of Automake
838 proscribed multiple conditional definitions of some variables
848 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
849 This restriction has been lifted, and these variables now
850 support multiple conditional definitions as do other variables.
852 - Cleanup the definitions of $(distdir) and $(top_distdir).
853 $(top_distdir) now points to the root of the distribution
854 directory created during `make dist', as it did in Automake 1.4,
855 not to the root of the build tree as it did in intervening
856 versions. Furthermore these two variables are now only defined in
857 the top level Makefile, and passed to sub-directories when running
860 - The --no-force option now correctly checks the Makefile.in's
861 dependencies before deciding not to update it.
863 - Do not assume that make files are called Makefile in cleaning rules.
865 - Update .info files in the source tree, not in the build tree. This
866 is what the GNU Coding Standard recommend. Only Automake 1.7.x
867 used to update these files in the build tree (previous versions did
868 it in the source tree too), and it caused several problems, varying
869 from mere annoyance to portability issues.
871 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
872 when --add-missing and --force-missing are used. For backward
873 compatibility --add-missing will continue to install COPYING (in
874 `gnu' strictness) when none of these three files exist, but this
875 use is deprecated: you should better choose a license yourself and
876 install it once for all in your source tree (and in your code
879 - Fix ylwrap so that it does not overwrite header files that haven't
880 changed, as the inline rule already does.
882 - User-defined rules override automake-defined rules for the same
883 targets, even when rules do not have commands. This is not new
884 (and was documented), however some of the automake-generated
885 rules have escaped this principle in former Automake versions.
886 Rules for the following targets are affected by this fix:
888 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
889 info, info-am, install-data-am, install-exec-am, install-info,
890 install-info-am, install-man, installcheck-am, maintainer-clean,
891 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
892 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
894 Practically it means that an attempt to supplement the dependencies
895 of some target, as in
899 will now *silently override* the automake definition of the
900 rule for this target. Running `automake -Woverride' will diagnose
901 all such overriding definitions.
903 It should be noted that almost all these targets support a *-local
904 variant that is meant to supplement the automake-defined rule
905 (See node `Extending' in the manual). The above rule should
908 clean-local: my-clean-rule
910 These *-local targets have been documented since at least
911 Automake 1.2, so you should not fear the change if you have
912 to support multiple automake versions.
916 - The Automake manual is now distributed under the terms of the GNU FDL.
918 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
920 - core dumps are no longer removed by the cleaning rules. There are
921 at least three reasons for this:
922 1. These files should not be created by any build step,
923 so their removal do not fit any of the cleaning rules.
924 Actually, they may be precious to the developer.
925 2. If such file is created during a build, then it's clearly a
926 bug Automake should not hide. Not removing the file will
927 cause `make distcheck' to complain about its presence.
928 3. Operating systems have different naming conventions for
929 core dump files. A core file on one system might be a
930 completely legitimate data file on another system.
932 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
933 defined by Automake. This means that any definition in the
934 environment will be used, unless overridden in the Makefile.am or
935 on the command line. The old behavior, where these variables were
936 defined empty in each Makefile, can be obtained by AC_SUBSTing or
937 AC_ARG_VARing each variable from configure.ac.
939 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
940 documented. (The is not a new feature, these variables have
941 been there since at least Automake 1.4.)
944 * Fix install-strip to work with nobase_ binaries.
945 * Fix renaming of #line directives in ylwrap.
946 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
949 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
950 * Fix detection of Debian's install-info, broken since version 1.5.
951 (Debian bug #213524).
952 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
953 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
956 * The implementation of automake's --no-force option is unreliable,
957 so this option is ignored in this version. A real fix will appear in
958 Automake 1.8. (Debian Bug #206299)
959 * AM_PATH_PYTHON: really check the whole list of interpreters if no
960 argument is given. (PR/399)
961 * Do not warn about leading `_' in variable names, even with -Wportability.
962 * Support user redefinitions of TEXINFO_TEX.
963 * depcomp: support AIX Compiler version 6.
964 * Fix missing rebuilds during `make dist' with BSD make.
965 (Could produce tarballs containing out-of-date files.)
966 * Resurrect multilib support.
967 * Noteworthy manual updates:
968 - Extending aclocal: how to write m4 macros that won't trigger warnings
970 - A Shared Library: Rewrite and split into subsections.
973 * Fix depcomp's icc mode for ICC 7.1.
974 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
975 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
976 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
977 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
978 * Remove Latin-1 characters from elisp-comp.
979 * Update the manual's @dircategory to match the Free Software Directory.
982 * Update install-sh's license to remove an advertising clause.
984 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
985 that caused invalid Makefile.ins to be generated.
986 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
987 * New FAQ entry: renamed objects.
990 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
991 the Emacs implementation)
992 * Fix output of aclocal.m4 dependencies in subdirectories.
993 * Use `mv -f' instead of `mv' in fastdep rules.
994 * Upgrade mdate-sh to work on OS/2.
995 * Don't byte-compile elisp files when ELCFILES is set empty.
996 (this documented feature was broken by 1.7.3)
997 * Diagnose trailing backslashes on last line of Makefile.am.
998 * Diagnose whitespace following trailing backslashes.
999 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
1000 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
1002 * `make install' will build `BUILT_SOURCES' first.
1003 * Minor documentation fixes.
1005 Bugs fixed in 1.7.3:
1006 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1007 * Query distutils for `pythondir' and `pythonexecdir', instead of
1008 using an hardcoded path. This should allow builds on 64-bit
1009 distributions that usually use lib64/ instead of lib/.
1010 * AM_PATH_PYTHON will also search for python2.3.
1011 * elisp files are now built all at once instead of one by one. Besides
1012 incurring a speed-up, this is required to support interdependent elisp files.
1013 * Support for DJGPP:
1014 - `make distcheck' will now work in `_inst/' and `_build' instead
1015 of `=inst/' and `=build/'
1016 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1017 - install/uninstall `*.i[0-9][0-9]'-style info files
1018 - more changes that affect only the Automake package (not its output)
1019 * Fix some incompatibilities with upcoming perl-5.10.
1020 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1021 PACKAGE and VERSION.
1023 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1024 is troublesome with gcc and Solaris compilers. (PR/385)
1025 - makedepend mode: work with Libtool. (PR/385 too)
1027 * better support for unusual gettext setups, such as multiple po/ directories
1029 - Flag missing po/ and intl/ directories as warnings, not errors.
1030 - Disable these warnings if po/ does not exist.
1031 * Noteworthy manual updates:
1033 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1035 - Document `AM_YFLAGS = -d'. (PR/382)
1037 Bugs fixed in 1.7.2:
1038 * Fix installation and uninstallation of Info files built in subdirectories.
1039 * Do not run `./configure --with-included-gettext' during `make distcheck'
1040 if AM_GNU_GETTEXT([external]) is used.
1041 * Correctly uninstall renamed man pages.
1042 * Do not strip escaped newline in variables defined in one condition
1043 and augmented in another condition.
1044 * Fix ansi2knr rules for LIBOBJS sources.
1045 * Clean all known Texinfo index files, not only those which appear to
1046 be used, because we cannot know wich indexes are used in included files.
1047 (PR/375, Debian Bug #168671)
1048 * Honor only the first @setfilename seen in a Texinfo file.
1049 * Treat "required file X not found" diagnostics as errors (exit status 1).
1050 * Don't complain that a required file is not found when it is a Makefile
1052 * Don't use single suffix inference rules when building `.info'-less
1053 Info files, for the sake of Solaris make.
1054 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1055 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1056 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1057 * Fix building of deansified files from subdirectories. (PR/370)
1058 * Add missing `fi' in the .c->.obj rules.
1059 * Improve install-sh to work even when names contain spaces or certain
1060 (but not all) shell metachars.
1061 * Fix the following spurious failures in the test suite:
1062 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1063 * Noteworthy manual updates:
1064 - Augment the section about BUILT_SOURCES.
1065 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1067 Bugs fixed in 1.7.1:
1068 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1070 * Aclocal should now recognize macro names containing parentheses, e.g.
1071 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1072 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1074 * Install Python files even if they were built. (PR/369)
1075 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1076 version might not be defined in the latter. (PR/358)
1077 * Reorder arguments passed to a couple of commands, so things works
1078 when POSIXLY_CORRECT=1.
1079 * Fix a regex that can cause Perl to segfault on large input.
1081 * Fix distribution of packages that have some sources defined conditionally,
1082 as in the `Conditional compilation using Automake conditionals' example
1084 * Fix spurious test suite failures on IRIX.
1085 * Don't report a required variable as undefined if it has been
1086 defined conditionally for the "right" conditions.
1087 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1088 `make distcheck' fails.
1089 * Fix distribution of included Makefile fragment, so we don't create
1090 spurious directories in the distribution. (PR/366)
1091 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1094 * Autoconf 2.54 is required.
1095 * `aclocal' and `automake' will no longer warn about obsolete
1096 configure macros. This is done by `autoconf -Wobsolete'.
1097 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1098 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1099 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1100 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1101 `configure.ac' for you.
1102 * Support for per-program and per-library `_CPPFLAGS'.
1103 * New `ctags' target (builds CTAGS files).
1104 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1105 (see `automake --help' or the manual for a list of them).
1106 * Honor the WARNINGS environment variable.
1107 * Omit the call to depcomp when using gcc3: call the compiler directly.
1108 * A new option, std-options, tests that programs support --help and --version
1109 when `make installcheck' is run. This is enabled by --gnits.
1110 * Texinfo rules now support the `ps' and `pdf' targets.
1111 * Info files are now created in the build directory, not the source directory.
1112 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1114 * `make distcheck' will enforce DESTDIR support by attempting
1116 * `+=' can be used in conditionals, even if the augmented variable
1117 was defined for another condition.
1118 * Makefile fragments (inserted with `include') are always distributed.
1119 * Use Autoconf's --trace interface to inspect configure.ac and get
1120 a more accurate view of it.
1121 * Add support for extending aclocal's default macro search path
1122 using a `dirlist' file within the aclocal directory.
1123 * automake --output-dir is deprecated.
1124 * The part of the distcheck target that checks whether uninstall actually
1125 removes all installed files has been moved in a separate target,
1126 distuninstallcheck, so it can be overridden easily.
1130 * Support for AM_INIT_GETTEXT([external])
1131 * Bug fixes, including:
1132 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1133 - nobase_ programs and scripts honor --program-transform correctly.
1134 - Erase configure.lineno during `make distclean'.
1135 - Erase YACC and LEX outputs during `make maintainer-clean'.
1138 * Many bug fixes, including:
1139 - Requiring the current version works.
1140 - Fix "$@" portability issues (for Zsh).
1141 - Fix output of dummy dependency files in presence of post-processed
1143 - Don't compute dependencies in background to avoid races with libtool.
1144 - Fix handling of _OBJECTS variables for targets sharing source variables.
1145 - Check dependency mode for Java when AM_PROG_GCJ is used.
1148 * automake --output-dir is deprecated
1149 * Many bug fixes, including:
1150 - Don't choke on AM_LDFLAGS definitions.
1151 - Clean libtool objects from subdirectories.
1152 - Allow configure variables with reserved suffix and unknown prefix
1153 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1154 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1157 * Autoconf 2.52 is required.
1158 * automake no longer run libtoolize.
1159 This is the job of autoreconf (from GNU Autoconf).
1160 * `dist' generates all the archive flavors, as did `dist-all'.
1161 * `dist-gzip' generates the Gzip tar file only.
1162 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1163 explosion. Makefile.in's keep a reasonable size.
1164 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1165 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1167 * `#line' of Lex and Yacc files are properly set.
1168 * EXTRA_DIST can contain generated directories.
1169 * Support for dot-less extensions in suffix rules.
1170 * The part of the distcheck target that checks whether distclean actually
1171 cleans all built files has been moved in a separate target, distcleancheck,
1172 so it can be overridden easily.
1173 * `make distcheck' will pass additional options defined in
1174 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1175 * Fixed CDPATH portability problems, in particular for MacOS X.
1176 * Fixed handling of nobase_ targets.
1177 * Fixed support of implicit rules leading to .lo objects.
1178 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1179 * Added uninstall-hook target
1180 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1181 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1182 (Note that "pkgname" is not "tarname", see the manual for details.)
1183 It is also possible to pass a list of global Automake options as
1184 first argument to this new form of AM_INIT_AUTOMAKE.
1185 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1186 to be a real assembler.
1187 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1188 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1189 * aclocal and automake are also installed with the version number
1190 appended, and some of the install directory names have changed.
1191 This lets you have multiple versions installed simultaneously.
1192 * Support for parsers and lexers in subdirectories.
1195 * Support for `configure.ac'.
1196 * Support for `else COND', `endif COND' and negated conditions `!COND'.
1197 * `make dist-all' is much faster.
1198 * Allows '@' AC_SUBSTs in macro names.
1199 * Faster AM_INIT_AUTOMAKE (requires update of `missing' script)
1200 * User-side dependency tracking. Developers no longer need GNU make
1202 * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional
1203 * Most files are correctly handled if they appear in subdirs
1204 For instance, a _DATA file can appear in a subdir
1205 * GNU tar is no longer required for `make dist'
1206 * Added support for `dist_' and `nodist_' prefixes
1207 * Added support for `nobase_' prefix
1208 * Compiled Java support
1209 * Support for per-executable and per-library compilation flags
1213 * Added support for the Fortran 77 programming language.
1214 * Re-indexed the Automake Texinfo manual.
