3 * Miscellaneous Changes:
5 - In 1.10b, the `parallel-tests' driver introduced per-extension test
6 driver variables `<EXT>_LOG_COMPILER', defined as
8 $(<EXT>_LOG_COMPILE) $(AM_<EXT>_LOG_FLAGS) $(<EXT>_LOG_FLAGS)
10 for extensions `.ext' registered in `TEST_EXTENSIONS'. Now, for tests
11 without a known extension, add `LOG_COMPILER', defined as
13 $(LOG_COMPILE) $(AM_LOG_FLAGS) $(LOG_FLAGS)
17 - The new `parallel-tests' targets `recheck' and `recheck-html' will not run
18 any tests that have not run yet.
24 - Texinfo dvi, ps, pdf, and html output files are not removed upon
25 `make mostlyclean' any more; only the LaTeX by-products are.
27 - Renamed objects also work with the `subdir-objects' option and
28 source file languages which Automake does not know itself.
30 * Bugs introduced by 1.10:
32 - The `parallel-tests' driver also works on systems with a nonempty
33 executable extension, such as Windows.
38 * Version requirements:
40 - Autoconf 2.62 or greater is required.
44 - The autoconf version check implemented by aclocal in aclocal.m4
45 (and new in Automake 1.10) is degraded to a warning. This helps
46 in the common case where the Autoconf versions used are compatible.
48 * Changes to automake:
50 - The automake program can run multiple threads for creating most
51 Makefile.in files concurrently, if at least Perl 5.7.2 is available
52 with interpreter-based threads enabled. Set the environment variable
53 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
54 enable this experimental feature.
56 * Changes to Libtool support:
58 - Libtool generic flags are now passed to the install and uninstall
61 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
62 config.lt is removed correctly now.
66 - subdir-object mode works now with Fortran (F77, FC, preprocessed
69 - For files with extension .f90, .f95, .f03, or .f08, the flag
70 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
72 - Files with extension .sx are also treated as preprocessed assembler.
74 - Python 3.0 is supported now, Python releases prior to 2.0 are no
77 - The default source file extension (.c) can be overridden with
78 AM_DEFAULT_SOURCE_EXT now.
80 * Miscellaneous changes:
82 - Automake development is done in a git repository on Savannah now, see
84 http://git.sv.gnu.org/gitweb/?p=automake.git
86 A read-only CVS mirror is provided at
88 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
89 checkout -d automake HEAD
91 - "make dist" can now create xz-compressed tarballs,
92 as well as (deprecated?) lzma-compressed tarballs.
94 - Automake is licensed under GPLv3+. `automake --add-missing' will
95 by default install the GPLv3 file as COPYING if it is missing.
96 It will also warn that the license file should be added to source
97 control. Note that Automake will never overwrite an existing COPYING
98 file, even when the `--force-missing' option is used.
100 - The manual is now distributed under the terms of the GNU FDL 1.3.
102 - Automake ships and installs man pages for automake and aclocal now.
104 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
106 - install-sh supports -C, which does not update the installed file
107 (and its time stamps) if the contents did not change.
109 - The `gnupload' script has been revamped.
111 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
113 - The targets `install' and `uninstall' are more efficient now, in that
114 for example multiple files from one Automake variable such as
115 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
116 invocation if they do not have to be renamed.
118 Both install and uninstall may sometimes enter (`cd' into) the target
119 installation directory now, when no build-local scripts are used.
121 Both install and uninstall do not fail anymore but do nothing if an
122 installation directory variable like `bindir' is set to the empty string.
124 For built-in rules, `make install' now fails reliably if installation
125 of a file failed. Conversely, `make uninstall' even succeeds when
126 issued multiple times.
128 These changes may need some adjustments from users: For example,
129 some `install' programs refuse to install multiple copies of the
130 same file in one invocation, so you may need to remove duplicate
131 entries from file lists.
133 Also, within one set of files, say, nobase_data_DATA, the order of
134 installation may be changed, or even unstable among different hosts,
135 due to the use of associative arrays in awk. The increased use of
136 awk matches a similar move in Autoconf to provide for better scaling.
138 Further, most undocumented per-rule install command variables such as
139 binSCRIPT_INSTALL have been removed because they are not needed any
140 more. Packages which use them should be using the appropriate one of
141 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
142 counterpart, depending on the type of files and the need for automatic
143 target directory creation.
145 - The "deleted header file problem" for *.m4 files is avoided by
146 stub rules. This allows `make' to trigger a rerun of `aclocal'
147 also if some previously needed macro file has been removed.
149 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
150 an otherwise up to date tree.
152 - The `color-tests' option causes colored test result output on terminals.
154 - The `parallel-tests' option enables a new test driver that allows for
155 parallel test execution, inter-test dependencies, lazy test execution
156 for unit-testing, and formatted result output as RST (reStructuredText)
157 and HTML. Enabling this option may require some changes to your test
158 suite setup; see the manual for details.
160 - The `silent-rules' option enables Linux kernel-style silent build output.
161 This option requires the widely supported but non-POSIX `make' feature
162 of recursive variable expansion, so do not use it if your package needs
163 to build with `make' implementations that do not support it.
164 Besides the normal option setting methods, it can also be enabled
165 globally by the new automake option `--silent-rules'.
167 - New prefix `notrans_' for manpages which should not be transformed
168 by --program-transform.
170 - New macro AM_COND_IF for conditional evaluation and conditional
173 - For AC_CONFIG_LINKS, if source and destination are equal, do not
174 remove the file in a non-VPATH build. Such setups work with Autoconf
177 - AM_MAINTAINER_MODE now allows for an optional argument specifying
180 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
181 useful especially for multi-line values.
183 - Automake's early configure-time sanity check now diagnoses an
184 unsafe absolute source directory name and makes configure fail.
186 - The Automake macros and rules cope better with whitespace in the
187 current directory name, as long as the relative path to `configure'
188 does not contain whitespace. To this end, the values of `$(MISSING)'
189 and `$(install_sh)' may contain suitable quoting, and their expansion
190 might need `eval'uation if used outside of a makefile. These
191 undocumented variables may be used in several documented macros such
192 as $(AUTOCONF) or $(MAKEINFO).
196 * Long standing bugs:
198 - Fix aix dependency tracking for libtool objects.
200 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
201 unnecessary use of the `compile' script.
203 - For nobase_*_LTLIBRARIES with nonempty directory components, the
204 correct `-rpath' argument is used now.
206 - `config.status --file=Makefile depfiles' now also works with the
207 extra quoting used internally by Autoconf 2.62 and newer
208 (it used to work only without the `--file=' bit).
210 - The `missing' script works better with versioned tool names.
212 - Semantics for `missing help2man' have been revamped:
214 Previously, if `help2man' was not present, `missing help2man' would have
215 the following semantics: if some man page was out of date but present, then
216 a warning would be printed, but the exit status was 0. If the man page was
217 not present at all, then `missing' would create a replacement man page
218 containing an error message, and exit with a status of 2. This does not play
219 well with `make': the next run will see this particular man page as being up
220 to date, and will only error out on the next generated man page, if any;
221 repeat until all pages are done. This was not desirable.
223 These are the new semantics: if some man page is not present, and help2man
224 is not either, then `missing' will warn and generate the replacement page
225 containing the error message, but exit successfully. However, `make dist'
226 will ensure that no such bogus man pages are packaged into a tarball.
228 - Targets provided by automake behave better with `make -n', in that they
229 take care not to create files.
231 - `config.status Makefile... depfiles' works fine again in the presence of
232 disabled dependency tracking.
234 - The default no-op recursive rules for these targets also work with BSD make
235 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
237 - `make distcheck' works also when both a directory and some file below it
238 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
240 * Bugs introduced by 1.10:
242 - Fix output of dummy dependency files in presence of post-processed
243 Makefile.in's again, but also cope with long lines.
245 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
246 that have been declared as programs in the same Makefile.
247 This is for consistency with the analogous change to TESTS in 1.10.
249 - Fix order of standard includes to again be `-I. -I$(srcdir)',
250 followed by directories containing config headers.
254 * Version requirements:
256 - Autoconf 2.60 or greater is required.
258 - Perl 5.6 or greater is required.
260 * Changes to aclocal:
262 - aclocal now also supports -Wmumble and -Wno-mumble options.
264 - `dirlist' entries (for the aclocal search path) may use shell
265 wildcards such as `*', `?', or `[...]'.
267 - aclocal supports an --install option that will cause system-wide
268 third-party macros to be installed in the local directory
269 specified with the first -I flag. This option also uses #serial
270 lines in M4 files to upgrade local macros.
272 The new aclocal options --dry-run and --diff help to review changes
273 before they are installed.
275 - aclocal now outputs an autoconf version check in aclocal.m4 in
276 projects using automake.
278 For a few years, automake and aclocal have been calling autoconf
279 (or its underlying engine autom4te) to accurately retrieve the
280 data they need from configure.ac and its siblings. Doing so can
281 only work if all autotools use the same version of autoconf. For
282 instance a Makefile.in generated by automake for one version of
283 autoconf may stop working if configure is regenerated with another
284 version of autoconf, and vice versa.
286 This new version check ensures that the whole build system has
287 been generated using the same autoconf version.
289 * Support for new Autoconf macros:
291 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
293 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
294 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
295 in different directories. However, only one instance of such a
296 library objects directory is supported.
298 * Change to Libtool support:
300 - Libtool generic flags (those that go before the --mode=MODE option)
301 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
303 * Yacc and Lex changes:
305 - The rebuild rules for distributed Yacc and Lex output will avoid
306 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
309 - ylwrap is now always used for lex and yacc source files,
310 regardless of whether there is more than one source per directory.
314 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
315 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
316 tracking, unlike non-preprocessed assembler (*.s).
318 - subdir-object mode works now with Assembler. Automake assumes
319 that the compiler understands `-c -o'.
321 - Preprocessed assembler (*.S) compilation now also honors
322 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
324 - Improved support for Objective C:
325 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
326 - A new section of the manual documents the support.
328 - New support for Unified Parallel C:
329 - AM_PROG_UPC looks for a UPC compiler.
330 - A new section of the manual documents the support.
332 - Per-target flags are now correctly handled in link rules.
334 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
335 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
336 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
337 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
339 The fix for compiler flags (i.e., using maude_CFLAGS instead of
340 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
341 is expected to work (and actually works during compilation).
343 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
344 "in addition to" breaks backward compatibility with older versions.
345 If your package used both variables, as in
347 AM_LDFLAGS = common flags
349 a_LDFLAGS = more flags
352 and assumed *_LDFLAGS would sum up, you should rewrite it as
354 AM_LDFLAGS = common flags
356 a_LDFLAGS = $(AM_LDFLAGS) more flags
359 This new behavior of *_LDFLAGS is more coherent with other
360 per-target variables, and the way *_LDFLAGS variables were
361 considered internally.
363 * New installation targets:
365 - New targets mandated by GNU Coding Standards:
370 By default they will only install Texinfo manuals.
371 You can customize them with *-local variants:
377 - The undocumented recursive target `uninstall-info' no longer exists.
378 (`uninstall' is in charge of removing all possible documentation
379 flavors, including optional formats such as dvi, ps, or info even
380 when `no-installinfo' is used.)
382 * Miscellaneous changes:
384 - Automake no longer complains if input files for AC_CONFIG_FILES
385 are specified using shell variables.
387 - clean, distribution, or rebuild rules are normally disabled for
388 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
389 AC_CONFIG_LINK specified using shell variables. However, if these
390 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
391 be able to output rules anyway.
392 (See the Automake documentation for AC_CONFIG_FILES.)
394 - $(EXEEXT) is automatically appended to filenames of TESTS
395 that have been declared as programs in the same Makefile.
396 This is mostly useful when some check_PROGRAMS are listed in TESTS.
398 - `-Wportability' has finally been turned on by default for `gnu' and
399 `gnits' strictness. This means, automake will complain about %-rules
400 or $(GNU Make functions) unless you switch to `foreign' strictness or
401 use `-Wno-portability'.
403 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
404 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
405 $(mkdir_p) variable is still defined (to the same value as
406 $(MKDIR_P)) but should be considered obsolete. If you are using
407 $(mkdir_p) in some of your rules, please plan to update them to
408 $(MKDIR_P) at some point.
410 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
411 They still work in this release, but may be withdrawn in a future one.
413 - Inline compilation rules for gcc3-style dependency tracking are
416 - Automake installs a "Hello World!" example package in $(docdir).
417 This example is used throughout the new "Autotools Introduction"
418 chapter of the manual.
422 * Makefile.in bloat reduction:
424 - Inference rules are used to compile sources in subdirectories when
425 the `subdir-objects' option is used and no per-target flags are
426 used. This should reduce the size of some projects a lot, because
427 Automake used to output an explicit rule for each such object in
430 - Automake no longer outputs three rules (.o, .obj, .lo) for each
431 object that must be built with explicit rules. It just outputs
432 the rules required to build the kind of object considered: either
433 the two .o and .obj rules for usual objects, or the .lo rule for
436 * Change to Libtool support:
438 - Libtool tags are used with libtool versions that support them.
439 (I.e., with Libtool 1.5 or greater.)
441 - Automake is now able to handle setups where a libtool library is
442 conditionally installed in different directories, as in
445 lib_LTLIBRARIES = liba.la
447 pkglib_LTLIBRARIES = liba.la
449 liba_la_SOURCES = ...
451 * Changes to aclocal:
453 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
454 really evaluated, before it decides to include them in aclocal.m4.
455 This solves nasty problems with conditional redefinitions of
456 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
457 *.m4 files to be included in any project using these macros.
458 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
459 most famous instance of this bug.)
461 - Do not complain about missing conditionally AC_REQUIREd macros
462 that are not actually used. In 1.8.x aclocal would correctly
463 determine which of these macros were really needed (and include
464 only these in the package); unfortunately it would also require
465 all of them to be present in order to run. This created
466 situations were aclocal would not work on a tarball distributing
467 all the macros it uses. For instance running aclocal on a project
468 containing only the subset of the Gettext macros in use by the
469 project did not work, because gettext conditionally requires other
472 * Portability improvements:
474 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
475 tar-pax. The new option filename-length-max=99 helps diagnosing
476 filenames that are too long for tar-v7. (PR/414)
478 - Variables aumented with `+=' are now automatically flattened (i.e.,
479 trailing backslashes removed) and then wrapped around 80 colummns
480 (adding trailing backslashes). In previous versions, a long series
486 would result in a single-line definition of VAR that could possibly
487 exceed the maximum line length of some make implementations.
489 Non-augmented variables are still output as they are defined in
494 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
495 Works the same as the old Fortran 77 implementation; just replace
496 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
497 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
499 - Support for conditional _LISP.
501 - Support for conditional -hook and -local rules (PR/428).
503 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
505 - Automake will not write any Makefile.ins after the first error it
506 encounters. The previous Makefile.ins (if any) will be left in
507 place. (Warnings will not prevent output, but remember they can
508 be turned into errors with -Werror.)
510 - The restriction that SUBDIRS must contain direct children is gone.
513 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
514 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
518 * Long standing bugs:
520 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
521 so that `make distclean' and `make maintainer-clean' can work.
523 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
525 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
527 - Polish diagnostic when no input file is found.
531 * Long standing bugs:
533 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
534 overridden by the user.
536 - Honor PATH_SEPARATOR in various places of the Automake package, for
539 - Adjust dependency tracking mode detection to ICC 8.0's new output.
542 - Fix install-sh so it can install the `mv' binary... using `mv'.
544 - Fix tru64 dependency tracking for libtool objects.
546 - Work around Exuberant Ctags when creating a TAGS files in a directory
547 without files to scan but with subdirectories to include.
549 * Bugs introduced by 1.8:
551 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
552 not defined in the same conditions as the _LDADD that uses it.
554 - Do not warn when JAVAROOT is overridden, this is legitimate.
558 * Long standing bugs:
560 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
561 or any of the other *dir variables contain a space.
563 Please note that Automake does not and cannot support spaces in
564 filenames that are involved during the build. This change affects
565 only installation paths, so that `make install' does not bomb out
566 in packages configured with
567 ./configure --prefix '/c/Program Files'
569 - Fix the depfiles output so it works with GNU sed (<4.1) even when
570 POSIXLY_CORRECT is set.
572 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
573 since Autoconf 2.54, which defines LIBOBJS itself.
575 - Fix a potential (but unlikely) race condition in parallel elisp
576 builds. (Introduced in 1.7.3.)
578 - Do not assume that users override _DEPENDENCIES in all conditions
579 where Automake will try to define them.
581 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
582 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
585 This fix also affects the $(mkdir_p) variable defined since
586 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
587 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
589 - Secure temporary directory creation in `make distcheck'. (PR/413)
591 - Do not generate two build rules for `parser.h' when the
592 parser appears in two different conditionals.
594 - Work around a Solaris 8 /bin/sh bug in the test for dependency
595 checking. Usually ./configure will not pick this shell; so this
596 fix only helps cases where the shell is forced to /bin/sh.
598 * Bugs introduced by 1.8:
600 - In some situations (hand-written `m4_include's), aclocal would
601 call the `File::Spec->rel2abs' method, which was only introduced
602 in Perl 5.6. This new version reestablish support Perl 5.005.
604 It is likely that the next major Automake releases will require at
605 least Perl 5.6. Consider upgrading your development environment
606 if you are still using the five-year-old Perl 5.005.
608 - Automake would sometimes fail to define rules for targets listed
609 in variables defined in multiple conditions. For instance on
615 it would define only the `a.$(OBJEXT): a.c' rule and omit the
616 `b.$(OBJEXT): b.c' rule.
618 * New sections in manual:
620 - Third-Party Makefiles: how to interface third party Makefiles.
621 - Upgrading: upgrading packages to newer Automake versions.
622 - Multiple Outputs: handling tools that produce many outputs.
626 * A (well known) portability bug slipped in the changes made to
627 install-sh in Automake 1.8.1. The broken install-sh would refuse to
628 install anything on Tru64.
630 * Fix install rules for conditionally built python files. (This never
635 * Bugs introduced by 1.8:
637 - Fix Config.pm import error with old Perl versions (at least
638 5.005_03). One symptom is that aclocal could not find its macro
641 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
642 created by `make install' are always world readable, even if the
643 installer happens to have an overly restrictive umask (e.g. 077).
644 This was a mistake and has been reverted. There are at least two
645 reasons why we must not use `-m 0755':
646 - it causes special bits like SGID to be ignored,
647 - it may be too restrictive (some setups expect 775 directories).
649 - Fix aclocal to honor definitions located in files which have been
650 m4_included manually. aclocal 1.8 had been updated to check
651 m4_included files for new requirements, but forgot that these
652 m4_included files can also provide new definitions.
654 Note that if you have such a setup, we recommend you get rid of
655 it. In the past, there was a reason to m4_include files manually:
656 aclocal used to duplicate entire M4 files into aclocal.m4, even
657 files that were distributed. Some packages were therefore
658 m4_including the distributed file directly, and playing some
659 tricks to ensure aclocal would not copy that file to aclocal.m4,
660 in order to limit the amount of duplication. Since aclocal 1.8.x
661 will precisely output m4_includes for local M4 files, we recommend
662 that you clean up your setup, removing all manual m4_includes and
663 letting aclocal output them.
665 - Output detailed menus in the Info version if the Automake manual,
666 so that Emacs can locate the indexes.
668 - configure.ac and configure were listed twice in DIST_COMMON (an
669 internal variable where Automake lists configury files to
670 distribute). This was harmless, but unaesthetic.
672 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
673 This was an issue only in the Automake package itself, not in
676 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
677 DEST:SRC. This was wrong, as some packages do
678 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
681 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
682 argument. This caused two kinds of failures:
683 - Rules installing data in a conditionally defined directory
684 failed when that directory was undefined. In this case no
685 argument was supplied.
686 - `make installdirs' failed, because several directories were
687 passed to $(mkdir_p). This was an issue only on platform
688 were $(mkdir_p) is implemented with `install-sh -d'.
689 $(mkdir_p) as been changed to accept 0 or more arguments, as
692 * Long-standing bugs:
694 - Fix an unexpected diagnostic occurring when users attempt
695 to override some internal variables that Automake appends to.
697 - aclocal now scans configure.ac for macro definitions (PR/319).
699 - Fix a portability issue with OSF1/Tru64 Make. If a directory
700 distributes files which are outside itself (this usually occurs
701 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
702 from a parent package), then `make distcheck' fails due to an
703 optimization performed by OSF1/Tru64 Make in its VPATH handling.
704 (tests/subpkg2.test failure)
706 - Fix another portability issue with Sun and OSF1/Tru64 Make.
707 In a VPATH-build configuration, `make install' would install
708 nobase_ files to wrong locations.
710 - Fix a Perl `uninitialized value' diagnostic occurring when
711 automake complains that a Texinfo file does not have a
712 @setfilename statement.
714 - Erase config.status.lineno during `make distclean'. This file
715 can be created by config.status. Automake already knew about
716 configure.lineno, but forgot config.status.lineno.
718 - Distribute all files, even those which are built and installed
719 conditionally. This change affects files listed in conditionally
720 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
721 as well as those listed in conditionally defined dist_*_DATA,
722 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
724 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
725 doesn't conform to POSIX.
727 - Normalize help strings for configure variables and options added
732 - Check for python2.4 in AM_PATH_PYTHON.
734 * Spurious failures in test suite:
736 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
737 tests/ltconv.test: fix failures with CVS Libtool.
738 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
739 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
740 fix failures with old Texinfo versions.
746 - The NEWS file is more verbose.
750 - Autoconf 2.58 or greater is required.
754 - Default source file names in the absence of a _SOURCES declaration
755 are made by removing any target extension before appending `.c', so
756 to make the libtool module `foo.la' from `foo.c', you only need to
759 lib_LTLIBRARIES = foo.la
760 foo_la_LDFLAGS = -module
762 For backward compatibility, foo_la.c will be used instead of
763 foo.c if this file exists or is the explicit target of a rule.
764 However -Wobsolete will warn about this deprecated naming.
766 - AR's `cru' flags are now set in a global ARFLAGS variable instead
767 of being hard-coded in each $(AR) invocation, so they can be
768 substituted from configure.ac. This has been requested by people
769 dealing with non-POSIX ar implementations.
771 - New warning option: -Woverride. This will warn about any user
772 target or variable definitions which override Automake
775 - Texinfo rules back up and restore info files when makeinfo fails.
777 - Texinfo rules now support the `html' target.
778 Running this requires Texinfo 4.0 or greater.
780 `html' is a new recursive target, so if your package mixes
781 hand-crafted `Makefile.in's with Automake-generated
782 `Makefile.in's, you should adjust the former to support (or
783 ignore) this target so that `make html' recurses successfully. If
784 you had a custom `html' rule in your `Makefile.am', it's better to
785 rename it as `html-local', otherwise your rule will override
786 Automake's new rule (you can check that by running `automake
787 -Woverride') and that will stop the recursion to subdirectories.
789 Last but not least, this `html' rule is declared PHONY, even when
790 overridden. Fortunately, it appears that few packages use a
791 non-PHONY `html' rule.
793 - Any file which is m4_included from configure.ac will appear as a
794 configure and Makefile.in dependency, and will be automatically
797 - The rules for rebuilding Makefiles and Makefile.ins will now
798 rebuild all Makefiles and all Makefile.ins at once when one of
799 configure's dependencies has changed. This is considerably faster
800 than previous implementations, where config.status and automake
801 were run separately in each directory (this still happens when you
802 change a Makefile.am locally, without touching configure.ac or
803 friends). Doing this also solves a longstanding issue: these
804 rebuild rules failed to work when adding new directories to the
805 tree, forcing you to run automake manually.
807 - For similar reasons, the rules to rebuild configure,
808 config.status, and aclocal.m4 are now defined in all directories.
809 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
810 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
811 should better define them in all directories. This is easily done
812 using an AC_SUBST (make sure you prefix these dependencies with
813 $(top_srcdir) since this variable will appear at different
814 levels of the build tree).
816 - aclocal will now use `m4_include' instead of copying local m4
817 files into aclocal.m4. (Local m4 files are those you ship with
818 your project, other files will be copied as usual.)
820 Because m4_included files are automatically distributed, it means
821 for most projects there is no point in EXTRA_DISTing the list of
822 m4 files which are used. (You can probably get rid of
823 m4/Makefile.am if you had one.)
825 - aclocal will avoid touching aclocal.m4 when possible, so that
826 Autom4te's cache isn't needlessly invalidated. This behavior can
827 be switched off with the new `--force' option.
829 - aclocal now uses Autoconf's --trace to detect macros which are
830 actually used and will no longer include unused macros simply
831 because they where mentioned. This was often the case for macros
832 called conditionally.
834 - New options no-dist and no-dist-gzip.
836 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
837 py-compile, and ylwrap, now all understand --version and --help.
839 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
840 links as part of the distclean target and including source files in
843 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
844 argument. The latter can be used to override the default behavior
847 - Automake will exit with $? = 63 on version mismatch. (So does
848 Autoconf 2.58) missing knows this, and in this case it will
849 emulate the tools as if they were absent. Because older versions
850 of Automake and Autoconf did not use this exit code, this change
851 will only be useful in projects generated with future versions of
854 - When using AC_CONFIG_FILES with multiple input files, Automake
855 generates the first ".in" input file for which a ".am" exists.
856 (Former versions would try to use only the first input file.)
858 - lisp_DATA is now allowed. If you are using the empty ELCFILES
859 idiom to disable byte-compilation of lisp_LISP files, it is
860 recommended that you switch to using lisp_DATA. Note that
861 this is not strictly equivalent: lisp_DATA will install elisp
862 files even if emacs is not installed, while *_LISP do not
863 install anything unless emacs is found.
865 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
866 available. This selection is achieved through the Makefile
867 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
868 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
869 `$(install_sh) -m 0755 -d'.
873 - Because `mkdir -p' is available on most platforms, and we can use
874 `install-sh -d' when it is not, the use of the mkinstalldirs
875 script is being phased out. `automake --add-missing' no longer
876 installs it, and if you remove mkinstalldirs from your package,
877 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
879 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
880 gettextize and autopoint will install it when needed. Automake
881 will continue to define the $(mkinstalldirs) and to distribute
882 mkinstalldirs when this script is in the source tree.
884 - AM_PROG_CC_STDC is now empty. The content of this macro was
885 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
886 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
887 renaming should be safe, even if you have to support several,
888 versions of Automake, because AC_PROG_CC defines this variable
889 since Autoconf 2.54.)
891 - Some users where using the undocumented ACLOCAL_M4_SOURCES
892 variable to override the aclocal.m4 dependencies computed
893 (inaccurately) by older versions of Automake. Because Automake
894 now tracks configure's m4 dependencies accurately (see m4_include
895 above), the use of ACLOCAL_M4_SOURCES should be considered
896 obsolete and will be flagged as such when running `automake
901 - Defining programs conditionally using Automake conditionals no
902 longer leads to a combinatorial explosion. The following
903 construct used to be troublesome when used with dozens of
918 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
920 - Due to implementation constraints, previous versions of Automake
921 proscribed multiple conditional definitions of some variables
931 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
932 This restriction has been lifted, and these variables now
933 support multiple conditional definitions as do other variables.
935 - Cleanup the definitions of $(distdir) and $(top_distdir).
936 $(top_distdir) now points to the root of the distribution
937 directory created during `make dist', as it did in Automake 1.4,
938 not to the root of the build tree as it did in intervening
939 versions. Furthermore these two variables are now only defined in
940 the top level Makefile, and passed to sub-directories when running
943 - The --no-force option now correctly checks the Makefile.in's
944 dependencies before deciding not to update it.
946 - Do not assume that make files are called Makefile in cleaning rules.
948 - Update .info files in the source tree, not in the build tree. This
949 is what the GNU Coding Standard recommend. Only Automake 1.7.x
950 used to update these files in the build tree (previous versions did
951 it in the source tree too), and it caused several problems, varying
952 from mere annoyance to portability issues.
954 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
955 when --add-missing and --force-missing are used. For backward
956 compatibility --add-missing will continue to install COPYING (in
957 `gnu' strictness) when none of these three files exist, but this
958 use is deprecated: you should better choose a license yourself and
959 install it once for all in your source tree (and in your code
962 - Fix ylwrap so that it does not overwrite header files that haven't
963 changed, as the inline rule already does.
965 - User-defined rules override automake-defined rules for the same
966 targets, even when rules do not have commands. This is not new
967 (and was documented), however some of the automake-generated
968 rules have escaped this principle in former Automake versions.
969 Rules for the following targets are affected by this fix:
971 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
972 info, info-am, install-data-am, install-exec-am, install-info,
973 install-info-am, install-man, installcheck-am, maintainer-clean,
974 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
975 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
977 Practically it means that an attempt to supplement the dependencies
978 of some target, as in
982 will now *silently override* the automake definition of the
983 rule for this target. Running `automake -Woverride' will diagnose
984 all such overriding definitions.
986 It should be noted that almost all these targets support a *-local
987 variant that is meant to supplement the automake-defined rule
988 (See node `Extending' in the manual). The above rule should
991 clean-local: my-clean-rule
993 These *-local targets have been documented since at least
994 Automake 1.2, so you should not fear the change if you have
995 to support multiple automake versions.
999 - The Automake manual is now distributed under the terms of the GNU FDL.
1001 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1003 - core dumps are no longer removed by the cleaning rules. There are
1004 at least three reasons for this:
1005 1. These files should not be created by any build step,
1006 so their removal do not fit any of the cleaning rules.
1007 Actually, they may be precious to the developer.
1008 2. If such file is created during a build, then it's clearly a
1009 bug Automake should not hide. Not removing the file will
1010 cause `make distcheck' to complain about its presence.
1011 3. Operating systems have different naming conventions for
1012 core dump files. A core file on one system might be a
1013 completely legitimate data file on another system.
1015 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1016 defined by Automake. This means that any definition in the
1017 environment will be used, unless overridden in the Makefile.am or
1018 on the command line. The old behavior, where these variables were
1019 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1020 AC_ARG_VARing each variable from configure.ac.
1022 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1023 documented. (The is not a new feature, these variables have
1024 been there since at least Automake 1.4.)
1026 Bugs fixed in 1.7.9:
1027 * Fix install-strip to work with nobase_ binaries.
1028 * Fix renaming of #line directives in ylwrap.
1029 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1031 Bugs fixed in 1.7.8:
1032 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1033 * Fix detection of Debian's install-info, broken since version 1.5.
1034 (Debian bug #213524).
1035 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1036 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1038 Bugs fixed in 1.7.7:
1039 * The implementation of automake's --no-force option is unreliable,
1040 so this option is ignored in this version. A real fix will appear in
1041 Automake 1.8. (Debian Bug #206299)
1042 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1043 argument is given. (PR/399)
1044 * Do not warn about leading `_' in variable names, even with -Wportability.
1045 * Support user redefinitions of TEXINFO_TEX.
1046 * depcomp: support AIX Compiler version 6.
1047 * Fix missing rebuilds during `make dist' with BSD make.
1048 (Could produce tarballs containing out-of-date files.)
1049 * Resurrect multilib support.
1050 * Noteworthy manual updates:
1051 - Extending aclocal: how to write m4 macros that won't trigger warnings
1053 - A Shared Library: Rewrite and split into subsections.
1055 Bugs fixed in 1.7.6:
1056 * Fix depcomp's icc mode for ICC 7.1.
1057 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1058 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1059 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1060 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1061 * Remove Latin-1 characters from elisp-comp.
1062 * Update the manual's @dircategory to match the Free Software Directory.
1064 Bugs fixed in 1.7.5:
1065 * Update install-sh's license to remove an advertising clause.
1066 (Debian bug #191717)
1067 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1068 that caused invalid Makefile.ins to be generated.
1069 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1070 * New FAQ entry: renamed objects.
1072 Bugs fixed in 1.7.4:
1073 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1074 the Emacs implementation)
1075 * Fix output of aclocal.m4 dependencies in subdirectories.
1076 * Use `mv -f' instead of `mv' in fastdep rules.
1077 * Upgrade mdate-sh to work on OS/2.
1078 * Don't byte-compile elisp files when ELCFILES is set empty.
1079 (this documented feature was broken by 1.7.3)
1080 * Diagnose trailing backslashes on last line of Makefile.am.
1081 * Diagnose whitespace following trailing backslashes.
1082 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
1083 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
1085 * `make install' will build `BUILT_SOURCES' first.
1086 * Minor documentation fixes.
1088 Bugs fixed in 1.7.3:
1089 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1090 * Query distutils for `pythondir' and `pythonexecdir', instead of
1091 using an hardcoded path. This should allow builds on 64-bit
1092 distributions that usually use lib64/ instead of lib/.
1093 * AM_PATH_PYTHON will also search for python2.3.
1094 * elisp files are now built all at once instead of one by one. Besides
1095 incurring a speed-up, this is required to support interdependent elisp files.
1096 * Support for DJGPP:
1097 - `make distcheck' will now work in `_inst/' and `_build' instead
1098 of `=inst/' and `=build/'
1099 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1100 - install/uninstall `*.i[0-9][0-9]'-style info files
1101 - more changes that affect only the Automake package (not its output)
1102 * Fix some incompatibilities with upcoming perl-5.10.
1103 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1104 PACKAGE and VERSION.
1106 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1107 is troublesome with gcc and Solaris compilers. (PR/385)
1108 - makedepend mode: work with Libtool. (PR/385 too)
1110 * better support for unusual gettext setups, such as multiple po/ directories
1112 - Flag missing po/ and intl/ directories as warnings, not errors.
1113 - Disable these warnings if po/ does not exist.
1114 * Noteworthy manual updates:
1116 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1118 - Document `AM_YFLAGS = -d'. (PR/382)
1120 Bugs fixed in 1.7.2:
1121 * Fix installation and uninstallation of Info files built in subdirectories.
1122 * Do not run `./configure --with-included-gettext' during `make distcheck'
1123 if AM_GNU_GETTEXT([external]) is used.
1124 * Correctly uninstall renamed man pages.
1125 * Do not strip escaped newline in variables defined in one condition
1126 and augmented in another condition.
1127 * Fix ansi2knr rules for LIBOBJS sources.
1128 * Clean all known Texinfo index files, not only those which appear to
1129 be used, because we cannot know wich indexes are used in included files.
1130 (PR/375, Debian Bug #168671)
1131 * Honor only the first @setfilename seen in a Texinfo file.
1132 * Treat "required file X not found" diagnostics as errors (exit status 1).
1133 * Don't complain that a required file is not found when it is a Makefile
1135 * Don't use single suffix inference rules when building `.info'-less
1136 Info files, for the sake of Solaris make.
1137 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1138 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1139 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1140 * Fix building of deansified files from subdirectories. (PR/370)
1141 * Add missing `fi' in the .c->.obj rules.
1142 * Improve install-sh to work even when names contain spaces or certain
1143 (but not all) shell metachars.
1144 * Fix the following spurious failures in the test suite:
1145 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1146 * Noteworthy manual updates:
1147 - Augment the section about BUILT_SOURCES.
1148 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1150 Bugs fixed in 1.7.1:
1151 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1153 * Aclocal should now recognize macro names containing parentheses, e.g.
1154 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1155 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1157 * Install Python files even if they were built. (PR/369)
1158 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1159 version might not be defined in the latter. (PR/358)
1160 * Reorder arguments passed to a couple of commands, so things works
1161 when POSIXLY_CORRECT=1.
1162 * Fix a regex that can cause Perl to segfault on large input.
1164 * Fix distribution of packages that have some sources defined conditionally,
1165 as in the `Conditional compilation using Automake conditionals' example
1167 * Fix spurious test suite failures on IRIX.
1168 * Don't report a required variable as undefined if it has been
1169 defined conditionally for the "right" conditions.
1170 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1171 `make distcheck' fails.
1172 * Fix distribution of included Makefile fragment, so we don't create
1173 spurious directories in the distribution. (PR/366)
1174 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1177 * Autoconf 2.54 is required.
1178 * `aclocal' and `automake' will no longer warn about obsolete
1179 configure macros. This is done by `autoconf -Wobsolete'.
1180 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1181 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1182 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1183 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1184 `configure.ac' for you.
1185 * Support for per-program and per-library `_CPPFLAGS'.
1186 * New `ctags' target (builds CTAGS files).
1187 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1188 (see `automake --help' or the manual for a list of them).
1189 * Honor the WARNINGS environment variable.
1190 * Omit the call to depcomp when using gcc3: call the compiler directly.
1191 * A new option, std-options, tests that programs support --help and --version
1192 when `make installcheck' is run. This is enabled by --gnits.
1193 * Texinfo rules now support the `ps' and `pdf' targets.
1194 * Info files are now created in the build directory, not the source directory.
1195 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1197 * `make distcheck' will enforce DESTDIR support by attempting
1199 * `+=' can be used in conditionals, even if the augmented variable
1200 was defined for another condition.
1201 * Makefile fragments (inserted with `include') are always distributed.
1202 * Use Autoconf's --trace interface to inspect configure.ac and get
1203 a more accurate view of it.
1204 * Add support for extending aclocal's default macro search path
1205 using a `dirlist' file within the aclocal directory.
1206 * automake --output-dir is deprecated.
1207 * The part of the distcheck target that checks whether uninstall actually
1208 removes all installed files has been moved in a separate target,
1209 distuninstallcheck, so it can be overridden easily.
1213 * Support for AM_INIT_GETTEXT([external])
1214 * Bug fixes, including:
1215 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1216 - nobase_ programs and scripts honor --program-transform correctly.
1217 - Erase configure.lineno during `make distclean'.
1218 - Erase YACC and LEX outputs during `make maintainer-clean'.
1221 * Many bug fixes, including:
1222 - Requiring the current version works.
1223 - Fix "$@" portability issues (for Zsh).
1224 - Fix output of dummy dependency files in presence of post-processed
1226 - Don't compute dependencies in background to avoid races with libtool.

1233 - Don't choke on AM_LDFLAGS definitions.
1234 - Clean libtool objects from subdirectories.
1235 - Allow configure variables with reserved suffix and unknown prefix
1236 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1237 - Fix the definition of AUTOMAKE and ACLOCAL in configure.

1265 (Note that "pkgname" is not "tarname", see the manual for details.)
1266 It is also possible to pass a list of global Automake options as
1267 first argument to this new form of AM_INIT_AUTOMAKE.
1268 * Compiler-based assembler is now called `CCAS'; people expected `AS'
