3 * WARNING: Future backward-incompatibilities!
5 - The Automake support for automatic de-ANSI-fication will be removed in
6 the next major Automake release (1.12).
8 * Miscellaneous changes:
10 - The `lzma' compression scheme and associated automake option `dist-lzma'
11 is obsoleted by `xz' and `dist-xz' due to upstream changes.
13 - The `compile' script now converts some options for MSVC for a better
14 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
16 - A developer that needs to pass specific flags to configure at "make
17 distcheck" time can now, and indeed he's advised to, do so by defining
18 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
19 instead of the old DISTCHECK_CONFIGURE_FLAGS.
20 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
21 user; still, the old Makefile.am files that used to define it should
22 still continue to work as before.
24 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
25 'ar-lib' auxiliary script if the found archiver is Microsoft lib. This
26 new macro is required for LIBRARIES and LTLIBRARIES when automake is
27 run with -Wportability (or -Wall) and -Werror.
29 Bugs fixed in 1.11.0a:
31 * Bugs introduced by 1.11:
33 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
34 trailing white space in the test list (`TESTS = foo $(EMPTY)'), and
35 does not report spurious successes when used with concurrent FreeBSD
36 make (e.g., "make check -j3").
38 - The `silent-rules' option now also silences all compile rules if dependency
39 tracking is disabled. Also, when `silent-rules' is not used, the output from
40 `make' does not contain spurious extra lines with only a backslash in them
41 any more; it now again matches that from pre-1.11 Automake.
43 - The `dist-xz' option now uses `xz -9' for maximum compression.
45 - The AM_COND_IF macro also works if the shell expression for the conditional
46 is no longer valid for the condition.
50 - Automake now warns about more primary/directory invalid combinations,
51 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
53 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
54 even if the `--prefix' argument pointed outside of a system directory.
55 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
56 `get_python_lib' function if it points outside the configured prefix,
57 unless the `--prefix' argument was either `/usr' or below `/System'.
59 - The testsuite does not try to change the mode of `ltmain.sh' files from
60 a Libtool installation (symlinked to test directories) any more.
62 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
63 tools are preferred in a cross-compile setup.
65 - Several scripts as well as the parallel-tests testsuite driver now
66 exit with the right exit status upon receiving a signal.
68 - A per-Makefile.am setting of -Werror does not carry over to the
69 handling of other Makefile.am files any more.
71 - The order of Yacc and Lex flags is fixed to be consistent with other
72 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
73 $(LFLAGS), so that the user variables override the developer variables.
75 - Rules generated by Automake now try harder to not change any files when
76 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
77 Yacc source files and the rule to update config.h.
79 - The code for automatic dependency tracking works around a Solaris
80 make bug triggered by sources containing repeated slashes when the
81 `subdir-objects' option was used.
83 - The parallel-tests driver now does not produce erroneous results
84 with Tru64/OSF 5.1 sh upon unreadable log files any more.
86 - The makedepend and hp depmodes now works better with VPATH builds.
88 - Java sources specified with check_JAVA are not compiled anymore upon
89 "make all", but only upon "make check".
91 - Now aclocal and automake, when they've to spawn autoconf or autom4te
92 processes, honour the configure-time definitions of AUTOCONF and
97 * Version requirements:
99 - Autoconf 2.62 or greater is required.
101 * Changes to aclocal:
103 - The autoconf version check implemented by aclocal in aclocal.m4
104 (and new in Automake 1.10) is degraded to a warning. This helps
105 in the common case where the Autoconf versions used are compatible.
107 * Changes to automake:
109 - The automake program can run multiple threads for creating most
110 Makefile.in files concurrently, if at least Perl 5.7.2 is available
111 with interpreter-based threads enabled. Set the environment variable
112 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
113 enable this experimental feature.
115 * Changes to Libtool support:
117 - Libtool generic flags are now passed to the install and uninstall
120 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
121 config.lt is removed correctly now.
125 - subdir-object mode works now with Fortran (F77, FC, preprocessed
126 Fortran, and Ratfor).
128 - For files with extension .f90, .f95, .f03, or .f08, the flag
129 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
131 - Files with extension .sx are also treated as preprocessed assembler.
133 - The default source file extension (.c) can be overridden with
134 AM_DEFAULT_SOURCE_EXT now.
136 - Python 3.0 is supported now, Python releases prior to 2.0 are no
139 - AM_PATH_PYTHON honors python's idea about the site directory.
141 - There is initial support for the Vala programming language, when using
144 * Miscellaneous changes:
146 - Automake development is done in a git repository on Savannah now, see
148 http://git.sv.gnu.org/gitweb/?p=automake.git
150 A read-only CVS mirror is provided at
152 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
153 checkout -d automake HEAD
155 - "make dist" can now create xz-compressed tarballs,
156 as well as (deprecated?) lzma-compressed tarballs.
158 - `automake --add-missing' will by default install the GPLv3 file as
159 COPYING if it is missing. It will also warn that the license file
160 should be added to source control. Note that Automake will never
161 overwrite an existing COPYING file, even when the `--force-missing'
164 - The manual is now distributed under the terms of the GNU FDL 1.3.
166 - Automake ships and installs man pages for automake and aclocal now.
168 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
170 - install-sh supports -C, which does not update the installed file
171 (and its time stamps) if the contents did not change.
173 - The `gnupload' script has been revamped.
175 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
177 - The targets `install' and `uninstall' are more efficient now, in that
178 for example multiple files from one Automake variable such as
179 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
180 invocation if they do not have to be renamed.
182 Both install and uninstall may sometimes enter (`cd' into) the target
183 installation directory now, when no build-local scripts are used.
185 Both install and uninstall do not fail anymore but do nothing if an
186 installation directory variable like `bindir' is set to the empty string.
188 For built-in rules, `make install' now fails reliably if installation
189 of a file failed. Conversely, `make uninstall' even succeeds when
190 issued multiple times.
192 These changes may need some adjustments from users: For example,
193 some `install' programs refuse to install multiple copies of the
194 same file in one invocation, so you may need to remove duplicate
195 entries from file lists.
197 Also, within one set of files, say, nobase_data_DATA, the order of
198 installation may be changed, or even unstable among different hosts,
199 due to the use of associative arrays in awk. The increased use of
200 awk matches a similar move in Autoconf to provide for better scaling.
202 Further, most undocumented per-rule install command variables such as
203 binSCRIPT_INSTALL have been removed because they are not needed any
204 more. Packages which use them should be using the appropriate one of
205 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
206 counterpart, depending on the type of files and the need for automatic
207 target directory creation.
209 - The "deleted header file problem" for *.m4 files is avoided by
210 stub rules. This allows `make' to trigger a rerun of `aclocal'
211 also if some previously needed macro file has been removed.
213 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
214 an otherwise up to date tree.
216 - The `color-tests' option causes colored test result output on terminals.
218 - The `parallel-tests' option enables a new test driver that allows for
219 parallel test execution, inter-test dependencies, lazy test execution
220 for unit-testing, re-testing only failed tests, and formatted result output
221 as RST (reStructuredText) and HTML. Enabling this option may require some
222 changes to your test suite setup; see the manual for details.
224 - The `silent-rules' option enables Linux kernel-style silent build output.
225 This option requires the widely supported but non-POSIX `make' feature
226 of recursive variable expansion, so do not use it if your package needs
227 to build with `make' implementations that do not support it.
229 To enable less verbose build output, the developer has to use the Automake
230 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
231 macro. The user may then set the default verbosity by passing the
232 `--enable-silent-rules' option to `configure'. At `make' run time, this
233 default may be overridden using `make V=0' for less verbose, and `make V=1'
234 for backward-compatible verbose output.
236 - New prefix `notrans_' for manpages which should not be transformed
237 by --program-transform.
239 - New macro AM_COND_IF for conditional evaluation and conditional
242 - For AC_CONFIG_LINKS, if source and destination are equal, do not
243 remove the file in a non-VPATH build. Such setups work with Autoconf
246 - AM_MAINTAINER_MODE now allows for an optional argument specifying
249 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
250 useful especially for multi-line values.
252 - Automake's early configure-time sanity check now diagnoses an
253 unsafe absolute source directory name and makes configure fail.
255 - The Automake macros and rules cope better with whitespace in the
256 current directory name, as long as the relative path to `configure'
257 does not contain whitespace. To this end, the values of `$(MISSING)'
258 and `$(install_sh)' may contain suitable quoting, and their expansion
259 might need `eval'uation if used outside of a makefile. These
260 undocumented variables may be used in several documented macros such
261 as $(AUTOCONF) or $(MAKEINFO).
265 * Long standing bugs:
267 - Fix aix dependency tracking for libtool objects.
269 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
270 unnecessary use of the `compile' script.
272 - For nobase_*_LTLIBRARIES with nonempty directory components, the
273 correct `-rpath' argument is used now.
275 - `config.status --file=Makefile depfiles' now also works with the
276 extra quoting used internally by Autoconf 2.62 and newer
277 (it used to work only without the `--file=' bit).
279 - The `missing' script works better with versioned tool names.
281 - Semantics for `missing help2man' have been revamped:
283 Previously, if `help2man' was not present, `missing help2man' would have
284 the following semantics: if some man page was out of date but present, then
285 a warning would be printed, but the exit status was 0. If the man page was
286 not present at all, then `missing' would create a replacement man page
287 containing an error message, and exit with a status of 2. This does not play
288 well with `make': the next run will see this particular man page as being up
289 to date, and will only error out on the next generated man page, if any;
290 repeat until all pages are done. This was not desirable.
292 These are the new semantics: if some man page is not present, and help2man
293 is not either, then `missing' will warn and generate the replacement page
294 containing the error message, but exit successfully. However, `make dist'
295 will ensure that no such bogus man pages are packaged into a tarball.
297 - Targets provided by automake behave better with `make -n', in that they
298 take care not to create files.
300 - `config.status Makefile... depfiles' works fine again in the presence of
301 disabled dependency tracking.
303 - The default no-op recursive rules for these targets also work with BSD make
304 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
306 - `make distcheck' works also when both a directory and some file below it
307 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
309 - Texinfo dvi, ps, pdf, and html output files are not removed upon
310 `make mostlyclean' any more; only the LaTeX by-products are.
312 - Renamed objects also work with the `subdir-objects' option and
313 source file languages which Automake does not know itself.
315 - `automake' now correctly complains about variable assignments which are
316 preceded by a comment, extend over multiple lines with backslash-escaped
317 newlines, and end in a comment sign. Previous versions would silently
318 and wrongly ignore such assignments completely.
320 * Bugs introduced by 1.10:
322 - Fix output of dummy dependency files in presence of post-processed
323 Makefile.in's again, but also cope with long lines.
325 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
326 that have been declared as programs in the same Makefile.
327 This is for consistency with the analogous change to TESTS in 1.10.
329 - Fix order of standard includes to again be `-I. -I$(srcdir)',
330 followed by directories containing config headers.
334 * Version requirements:
336 - Autoconf 2.60 or greater is required.
338 - Perl 5.6 or greater is required.
340 * Changes to aclocal:
342 - aclocal now also supports -Wmumble and -Wno-mumble options.
344 - `dirlist' entries (for the aclocal search path) may use shell
345 wildcards such as `*', `?', or `[...]'.
347 - aclocal supports an --install option that will cause system-wide
348 third-party macros to be installed in the local directory
349 specified with the first -I flag. This option also uses #serial
350 lines in M4 files to upgrade local macros.
352 The new aclocal options --dry-run and --diff help to review changes
353 before they are installed.
355 - aclocal now outputs an autoconf version check in aclocal.m4 in
356 projects using automake.
358 For a few years, automake and aclocal have been calling autoconf
359 (or its underlying engine autom4te) to accurately retrieve the
360 data they need from configure.ac and its siblings. Doing so can
361 only work if all autotools use the same version of autoconf. For
362 instance a Makefile.in generated by automake for one version of
363 autoconf may stop working if configure is regenerated with another
364 version of autoconf, and vice versa.
366 This new version check ensures that the whole build system has
367 been generated using the same autoconf version.
369 * Support for new Autoconf macros:
371 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
373 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
374 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
375 in different directories. However, only one instance of such a
376 library objects directory is supported.
378 * Change to Libtool support:
380 - Libtool generic flags (those that go before the --mode=MODE option)
381 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
383 * Yacc and Lex changes:
385 - The rebuild rules for distributed Yacc and Lex output will avoid
386 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
389 - ylwrap is now always used for lex and yacc source files,
390 regardless of whether there is more than one source per directory.
394 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
395 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
396 tracking, unlike non-preprocessed assembler (*.s).
398 - subdir-object mode works now with Assembler. Automake assumes
399 that the compiler understands `-c -o'.
401 - Preprocessed assembler (*.S) compilation now also honors
402 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
404 - Improved support for Objective C:
405 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
406 - A new section of the manual documents the support.
408 - New support for Unified Parallel C:
409 - AM_PROG_UPC looks for a UPC compiler.
410 - A new section of the manual documents the support.
412 - Per-target flags are now correctly handled in link rules.
414 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
415 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
416 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
417 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
419 The fix for compiler flags (i.e., using maude_CFLAGS instead of
420 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
421 is expected to work (and actually works during compilation).
423 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
424 "in addition to" breaks backward compatibility with older versions.
425 If your package used both variables, as in
427 AM_LDFLAGS = common flags
429 a_LDFLAGS = more flags
432 and assumed *_LDFLAGS would sum up, you should rewrite it as
434 AM_LDFLAGS = common flags
436 a_LDFLAGS = $(AM_LDFLAGS) more flags
439 This new behavior of *_LDFLAGS is more coherent with other
440 per-target variables, and the way *_LDFLAGS variables were
441 considered internally.
443 * New installation targets:
445 - New targets mandated by GNU Coding Standards:
450 By default they will only install Texinfo manuals.
451 You can customize them with *-local variants:
457 - The undocumented recursive target `uninstall-info' no longer exists.
458 (`uninstall' is in charge of removing all possible documentation
459 flavors, including optional formats such as dvi, ps, or info even
460 when `no-installinfo' is used.)
462 * Miscellaneous changes:
464 - Automake no longer complains if input files for AC_CONFIG_FILES
465 are specified using shell variables.
467 - clean, distribution, or rebuild rules are normally disabled for
468 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
469 AC_CONFIG_LINK specified using shell variables. However, if these
470 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
471 be able to output rules anyway.
472 (See the Automake documentation for AC_CONFIG_FILES.)
474 - $(EXEEXT) is automatically appended to filenames of TESTS
475 that have been declared as programs in the same Makefile.
476 This is mostly useful when some check_PROGRAMS are listed in TESTS.
478 - `-Wportability' has finally been turned on by default for `gnu' and
479 `gnits' strictness. This means, automake will complain about %-rules
480 or $(GNU Make functions) unless you switch to `foreign' strictness or
481 use `-Wno-portability'.
483 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
484 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
485 $(mkdir_p) variable is still defined (to the same value as
486 $(MKDIR_P)) but should be considered obsolete. If you are using
487 $(mkdir_p) in some of your rules, please plan to update them to
488 $(MKDIR_P) at some point.
490 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
491 They still work in this release, but may be withdrawn in a future one.
493 - Inline compilation rules for gcc3-style dependency tracking are
496 - Automake installs a "Hello World!" example package in $(docdir).
497 This example is used throughout the new "Autotools Introduction"
498 chapter of the manual.
502 * Makefile.in bloat reduction:
504 - Inference rules are used to compile sources in subdirectories when
505 the `subdir-objects' option is used and no per-target flags are
506 used. This should reduce the size of some projects a lot, because
507 Automake used to output an explicit rule for each such object in
510 - Automake no longer outputs three rules (.o, .obj, .lo) for each
511 object that must be built with explicit rules. It just outputs
512 the rules required to build the kind of object considered: either
513 the two .o and .obj rules for usual objects, or the .lo rule for
516 * Change to Libtool support:
518 - Libtool tags are used with libtool versions that support them.
519 (I.e., with Libtool 1.5 or greater.)
521 - Automake is now able to handle setups where a libtool library is
522 conditionally installed in different directories, as in
525 lib_LTLIBRARIES = liba.la
527 pkglib_LTLIBRARIES = liba.la
529 liba_la_SOURCES = ...
531 * Changes to aclocal:
533 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
534 really evaluated, before it decides to include them in aclocal.m4.
535 This solves nasty problems with conditional redefinitions of
536 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
537 *.m4 files to be included in any project using these macros.
538 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
539 most famous instance of this bug.)
541 - Do not complain about missing conditionally AC_REQUIREd macros
542 that are not actually used. In 1.8.x aclocal would correctly
543 determine which of these macros were really needed (and include
544 only these in the package); unfortunately it would also require
545 all of them to be present in order to run. This created
546 situations were aclocal would not work on a tarball distributing
547 all the macros it uses. For instance running aclocal on a project
548 containing only the subset of the Gettext macros in use by the
549 project did not work, because gettext conditionally requires other
552 * Portability improvements:
554 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
555 tar-pax. The new option filename-length-max=99 helps diagnosing
556 filenames that are too long for tar-v7. (PR/414)
558 - Variables aumented with `+=' are now automatically flattened (i.e.,
559 trailing backslashes removed) and then wrapped around 80 colummns
560 (adding trailing backslashes). In previous versions, a long series
566 would result in a single-line definition of VAR that could possibly
567 exceed the maximum line length of some make implementations.
569 Non-augmented variables are still output as they are defined in
574 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
575 Works the same as the old Fortran 77 implementation; just replace
576 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
577 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
579 - Support for conditional _LISP.
581 - Support for conditional -hook and -local rules (PR/428).
583 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
585 - Automake will not write any Makefile.ins after the first error it
586 encounters. The previous Makefile.ins (if any) will be left in
587 place. (Warnings will not prevent output, but remember they can
588 be turned into errors with -Werror.)
590 - The restriction that SUBDIRS must contain direct children is gone.
593 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
594 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
598 * Long standing bugs:
600 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
601 so that `make distclean' and `make maintainer-clean' can work.
603 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
605 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
607 - Polish diagnostic when no input file is found.
611 * Long standing bugs:
613 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
614 overridden by the user.
616 - Honor PATH_SEPARATOR in various places of the Automake package, for
619 - Adjust dependency tracking mode detection to ICC 8.0's new output.
622 - Fix install-sh so it can install the `mv' binary... using `mv'.
624 - Fix tru64 dependency tracking for libtool objects.
626 - Work around Exuberant Ctags when creating a TAGS files in a directory
627 without files to scan but with subdirectories to include.
629 * Bugs introduced by 1.8:
631 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
632 not defined in the same conditions as the _LDADD that uses it.
634 - Do not warn when JAVAROOT is overridden, this is legitimate.
638 * Long standing bugs:
640 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
641 or any of the other *dir variables contain a space.
643 Please note that Automake does not and cannot support spaces in
644 filenames that are involved during the build. This change affects
645 only installation paths, so that `make install' does not bomb out
646 in packages configured with
647 ./configure --prefix '/c/Program Files'
649 - Fix the depfiles output so it works with GNU sed (<4.1) even when
650 POSIXLY_CORRECT is set.
652 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
653 since Autoconf 2.54, which defines LIBOBJS itself.
655 - Fix a potential (but unlikely) race condition in parallel elisp
656 builds. (Introduced in 1.7.3.)
658 - Do not assume that users override _DEPENDENCIES in all conditions
659 where Automake will try to define them.
661 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
662 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
665 This fix also affects the $(mkdir_p) variable defined since
666 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
667 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
669 - Secure temporary directory creation in `make distcheck'. (PR/413)
671 - Do not generate two build rules for `parser.h' when the
672 parser appears in two different conditionals.
674 - Work around a Solaris 8 /bin/sh bug in the test for dependency
675 checking. Usually ./configure will not pick this shell; so this
676 fix only helps cases where the shell is forced to /bin/sh.
678 * Bugs introduced by 1.8:
680 - In some situations (hand-written `m4_include's), aclocal would
681 call the `File::Spec->rel2abs' method, which was only introduced
682 in Perl 5.6. This new version reestablish support Perl 5.005.
684 It is likely that the next major Automake releases will require at
685 least Perl 5.6. Consider upgrading your development environment
686 if you are still using the five-year-old Perl 5.005.
688 - Automake would sometimes fail to define rules for targets listed
689 in variables defined in multiple conditions. For instance on
695 it would define only the `a.$(OBJEXT): a.c' rule and omit the
696 `b.$(OBJEXT): b.c' rule.
698 * New sections in manual:
700 - Third-Party Makefiles: how to interface third party Makefiles.
701 - Upgrading: upgrading packages to newer Automake versions.
702 - Multiple Outputs: handling tools that produce many outputs.
706 * A (well known) portability bug slipped in the changes made to
707 install-sh in Automake 1.8.1. The broken install-sh would refuse to
708 install anything on Tru64.
710 * Fix install rules for conditionally built python files. (This never
715 * Bugs introduced by 1.8:
717 - Fix Config.pm import error with old Perl versions (at least
718 5.005_03). One symptom is that aclocal could not find its macro
721 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
722 created by `make install' are always world readable, even if the
723 installer happens to have an overly restrictive umask (e.g. 077).
724 This was a mistake and has been reverted. There are at least two
725 reasons why we must not use `-m 0755':
726 - it causes special bits like SGID to be ignored,
727 - it may be too restrictive (some setups expect 775 directories).
729 - Fix aclocal to honor definitions located in files which have been
730 m4_included manually. aclocal 1.8 had been updated to check
731 m4_included files for new requirements, but forgot that these
732 m4_included files can also provide new definitions.
734 Note that if you have such a setup, we recommend you get rid of
735 it. In the past, there was a reason to m4_include files manually:
736 aclocal used to duplicate entire M4 files into aclocal.m4, even
737 files that were distributed. Some packages were therefore
738 m4_including the distributed file directly, and playing some
739 tricks to ensure aclocal would not copy that file to aclocal.m4,
740 in order to limit the amount of duplication. Since aclocal 1.8.x
741 will precisely output m4_includes for local M4 files, we recommend
742 that you clean up your setup, removing all manual m4_includes and
743 letting aclocal output them.
745 - Output detailed menus in the Info version if the Automake manual,
746 so that Emacs can locate the indexes.
748 - configure.ac and configure were listed twice in DIST_COMMON (an
749 internal variable where Automake lists configury files to
750 distribute). This was harmless, but unaesthetic.
752 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
753 This was an issue only in the Automake package itself, not in
756 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
757 DEST:SRC. This was wrong, as some packages do
758 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
761 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
762 argument. This caused two kinds of failures:
763 - Rules installing data in a conditionally defined directory
764 failed when that directory was undefined. In this case no
765 argument was supplied.
766 - `make installdirs' failed, because several directories were
767 passed to $(mkdir_p). This was an issue only on platform
768 were $(mkdir_p) is implemented with `install-sh -d'.
769 $(mkdir_p) as been changed to accept 0 or more arguments, as
772 * Long-standing bugs:
774 - Fix an unexpected diagnostic occurring when users attempt
775 to override some internal variables that Automake appends to.
777 - aclocal now scans configure.ac for macro definitions (PR/319).
779 - Fix a portability issue with OSF1/Tru64 Make. If a directory
780 distributes files which are outside itself (this usually occurs
781 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
782 from a parent package), then `make distcheck' fails due to an
783 optimization performed by OSF1/Tru64 Make in its VPATH handling.
784 (tests/subpkg2.test failure)
786 - Fix another portability issue with Sun and OSF1/Tru64 Make.
787 In a VPATH-build configuration, `make install' would install
788 nobase_ files to wrong locations.
790 - Fix a Perl `uninitialized value' diagnostic occurring when
791 automake complains that a Texinfo file does not have a
792 @setfilename statement.
794 - Erase config.status.lineno during `make distclean'. This file
795 can be created by config.status. Automake already knew about
796 configure.lineno, but forgot config.status.lineno.
798 - Distribute all files, even those which are built and installed
799 conditionally. This change affects files listed in conditionally
800 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
801 as well as those listed in conditionally defined dist_*_DATA,
802 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
804 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
805 doesn't conform to POSIX.
807 - Normalize help strings for configure variables and options added
812 - Check for python2.4 in AM_PATH_PYTHON.
814 * Spurious failures in test suite:
816 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
817 tests/ltconv.test: fix failures with CVS Libtool.
818 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
819 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
820 fix failures with old Texinfo versions.
826 - The NEWS file is more verbose.
830 - Autoconf 2.58 or greater is required.
834 - Default source file names in the absence of a _SOURCES declaration
835 are made by removing any target extension before appending `.c', so
836 to make the libtool module `foo.la' from `foo.c', you only need to
839 lib_LTLIBRARIES = foo.la
840 foo_la_LDFLAGS = -module
842 For backward compatibility, foo_la.c will be used instead of
843 foo.c if this file exists or is the explicit target of a rule.
844 However -Wobsolete will warn about this deprecated naming.
846 - AR's `cru' flags are now set in a global ARFLAGS variable instead
847 of being hard-coded in each $(AR) invocation, so they can be
848 substituted from configure.ac. This has been requested by people
849 dealing with non-POSIX ar implementations.
851 - New warning option: -Woverride. This will warn about any user
852 target or variable definitions which override Automake
855 - Texinfo rules back up and restore info files when makeinfo fails.
857 - Texinfo rules now support the `html' target.
858 Running this requires Texinfo 4.0 or greater.
860 `html' is a new recursive target, so if your package mixes
861 hand-crafted `Makefile.in's with Automake-generated
862 `Makefile.in's, you should adjust the former to support (or
863 ignore) this target so that `make html' recurses successfully. If
864 you had a custom `html' rule in your `Makefile.am', it's better to
865 rename it as `html-local', otherwise your rule will override
866 Automake's new rule (you can check that by running `automake
867 -Woverride') and that will stop the recursion to subdirectories.
869 Last but not least, this `html' rule is declared PHONY, even when
870 overridden. Fortunately, it appears that few packages use a
871 non-PHONY `html' rule.
873 - Any file which is m4_included from configure.ac will appear as a
874 configure and Makefile.in dependency, and will be automatically
877 - The rules for rebuilding Makefiles and Makefile.ins will now
878 rebuild all Makefiles and all Makefile.ins at once when one of
879 configure's dependencies has changed. This is considerably faster
880 than previous implementations, where config.status and automake
881 were run separately in each directory (this still happens when you
882 change a Makefile.am locally, without touching configure.ac or
883 friends). Doing this also solves a longstanding issue: these
884 rebuild rules failed to work when adding new directories to the
885 tree, forcing you to run automake manually.
887 - For similar reasons, the rules to rebuild configure,
888 config.status, and aclocal.m4 are now defined in all directories.
889 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
890 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
891 should better define them in all directories. This is easily done
892 using an AC_SUBST (make sure you prefix these dependencies with
893 $(top_srcdir) since this variable will appear at different
894 levels of the build tree).
896 - aclocal will now use `m4_include' instead of copying local m4
897 files into aclocal.m4. (Local m4 files are those you ship with
898 your project, other files will be copied as usual.)
900 Because m4_included files are automatically distributed, it means
901 for most projects there is no point in EXTRA_DISTing the list of
902 m4 files which are used. (You can probably get rid of
903 m4/Makefile.am if you had one.)
905 - aclocal will avoid touching aclocal.m4 when possible, so that
906 Autom4te's cache isn't needlessly invalidated. This behavior can
907 be switched off with the new `--force' option.
909 - aclocal now uses Autoconf's --trace to detect macros which are
910 actually used and will no longer include unused macros simply
911 because they where mentioned. This was often the case for macros
912 called conditionally.
914 - New options no-dist and no-dist-gzip.
916 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
917 py-compile, and ylwrap, now all understand --version and --help.
919 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
920 links as part of the distclean target and including source files in
923 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
924 argument. The latter can be used to override the default behavior
927 - Automake will exit with $? = 63 on version mismatch. (So does
928 Autoconf 2.58) missing knows this, and in this case it will
929 emulate the tools as if they were absent. Because older versions
930 of Automake and Autoconf did not use this exit code, this change
931 will only be useful in projects generated with future versions of
934 - When using AC_CONFIG_FILES with multiple input files, Automake
935 generates the first ".in" input file for which a ".am" exists.
936 (Former versions would try to use only the first input file.)
938 - lisp_DATA is now allowed. If you are using the empty ELCFILES
939 idiom to disable byte-compilation of lisp_LISP files, it is
940 recommended that you switch to using lisp_DATA. Note that
941 this is not strictly equivalent: lisp_DATA will install elisp
942 files even if emacs is not installed, while *_LISP do not
943 install anything unless emacs is found.
945 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
946 available. This selection is achieved through the Makefile
947 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
948 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
949 `$(install_sh) -m 0755 -d'.
953 - Because `mkdir -p' is available on most platforms, and we can use
954 `install-sh -d' when it is not, the use of the mkinstalldirs
955 script is being phased out. `automake --add-missing' no longer
956 installs it, and if you remove mkinstalldirs from your package,
957 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
959 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
960 gettextize and autopoint will install it when needed. Automake
961 will continue to define the $(mkinstalldirs) and to distribute
962 mkinstalldirs when this script is in the source tree.
964 - AM_PROG_CC_STDC is now empty. The content of this macro was
965 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
966 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
967 renaming should be safe, even if you have to support several,
968 versions of Automake, because AC_PROG_CC defines this variable
969 since Autoconf 2.54.)
971 - Some users where using the undocumented ACLOCAL_M4_SOURCES
972 variable to override the aclocal.m4 dependencies computed
973 (inaccurately) by older versions of Automake. Because Automake
974 now tracks configure's m4 dependencies accurately (see m4_include
975 above), the use of ACLOCAL_M4_SOURCES should be considered
976 obsolete and will be flagged as such when running `automake
981 - Defining programs conditionally using Automake conditionals no
982 longer leads to a combinatorial explosion. The following
983 construct used to be troublesome when used with dozens of
998 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1000 - Due to implementation constraints, previous versions of Automake
1001 proscribed multiple conditional definitions of some variables
1011 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1012 This restriction has been lifted, and these variables now
1013 support multiple conditional definitions as do other variables.
1015 - Cleanup the definitions of $(distdir) and $(top_distdir).
1016 $(top_distdir) now points to the root of the distribution
1017 directory created during `make dist', as it did in Automake 1.4,
1018 not to the root of the build tree as it did in intervening
1019 versions. Furthermore these two variables are now only defined in
1020 the top level Makefile, and passed to sub-directories when running
1023 - The --no-force option now correctly checks the Makefile.in's
1024 dependencies before deciding not to update it.
1026 - Do not assume that make files are called Makefile in cleaning rules.
1028 - Update .info files in the source tree, not in the build tree. This
1029 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1030 used to update these files in the build tree (previous versions did
1031 it in the source tree too), and it caused several problems, varying
1032 from mere annoyance to portability issues.
1034 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1035 when --add-missing and --force-missing are used. For backward
1036 compatibility --add-missing will continue to install COPYING (in
1037 `gnu' strictness) when none of these three files exist, but this
1038 use is deprecated: you should better choose a license yourself and
1039 install it once for all in your source tree (and in your code
1042 - Fix ylwrap so that it does not overwrite header files that haven't
1043 changed, as the inline rule already does.
1045 - User-defined rules override automake-defined rules for the same
1046 targets, even when rules do not have commands. This is not new
1047 (and was documented), however some of the automake-generated
1048 rules have escaped this principle in former Automake versions.
1049 Rules for the following targets are affected by this fix:
1051 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1052 info, info-am, install-data-am, install-exec-am, install-info,
1053 install-info-am, install-man, installcheck-am, maintainer-clean,
1054 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1055 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1057 Practically it means that an attempt to supplement the dependencies
1058 of some target, as in
1060 clean: my-clean-rule
1062 will now *silently override* the automake definition of the
1063 rule for this target. Running `automake -Woverride' will diagnose
1064 all such overriding definitions.
1066 It should be noted that almost all these targets support a *-local
1067 variant that is meant to supplement the automake-defined rule
1068 (See node `Extending' in the manual). The above rule should
1071 clean-local: my-clean-rule
1073 These *-local targets have been documented since at least
1074 Automake 1.2, so you should not fear the change if you have
1075 to support multiple automake versions.
1079 - The Automake manual is now distributed under the terms of the GNU FDL.
1081 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1083 - core dumps are no longer removed by the cleaning rules. There are
1084 at least three reasons for this:
1085 1. These files should not be created by any build step,
1086 so their removal do not fit any of the cleaning rules.
1087 Actually, they may be precious to the developer.
1088 2. If such file is created during a build, then it's clearly a
1089 bug Automake should not hide. Not removing the file will
1090 cause `make distcheck' to complain about its presence.
1091 3. Operating systems have different naming conventions for
1092 core dump files. A core file on one system might be a
1093 completely legitimate data file on another system.
1095 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1096 defined by Automake. This means that any definition in the
1097 environment will be used, unless overridden in the Makefile.am or
1098 on the command line. The old behavior, where these variables were
1099 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1100 AC_ARG_VARing each variable from configure.ac.
1102 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1103 documented. (The is not a new feature, these variables have
1104 been there since at least Automake 1.4.)
1106 Bugs fixed in 1.7.9:
1107 * Fix install-strip to work with nobase_ binaries.
1108 * Fix renaming of #line directives in ylwrap.
1109 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1111 Bugs fixed in 1.7.8:
1112 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1113 * Fix detection of Debian's install-info, broken since version 1.5.
1114 (Debian bug #213524).
1115 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1116 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1118 Bugs fixed in 1.7.7:
1119 * The implementation of automake's --no-force option is unreliable,
1120 so this option is ignored in this version. A real fix will appear in
1121 Automake 1.8. (Debian Bug #206299)
1122 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1123 argument is given. (PR/399)
1124 * Do not warn about leading `_' in variable names, even with -Wportability.
1125 * Support user redefinitions of TEXINFO_TEX.
1126 * depcomp: support AIX Compiler version 6.
1127 * Fix missing rebuilds during `make dist' with BSD make.
1128 (Could produce tarballs containing out-of-date files.)
1129 * Resurrect multilib support.
1130 * Noteworthy manual updates:
1131 - Extending aclocal: how to write m4 macros that won't trigger warnings
1133 - A Shared Library: Rewrite and split into subsections.
1135 Bugs fixed in 1.7.6:
1136 * Fix depcomp's icc mode for ICC 7.1.
1137 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1138 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1139 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1140 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1141 * Remove Latin-1 characters from elisp-comp.
1142 * Update the manual's @dircategory to match the Free Software Directory.
1144 Bugs fixed in 1.7.5:
1145 * Update install-sh's license to remove an advertising clause.
1146 (Debian bug #191717)
1147 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1148 that caused invalid Makefile.ins to be generated.
1149 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1150 * New FAQ entry: renamed objects.
1152 Bugs fixed in 1.7.4:
1153 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1154 the Emacs implementation)
1155 * Fix output of aclocal.m4 dependencies in subdirectories.
1156 * Use `mv -f' instead of `mv' in fastdep rules.
1157 * Upgrade mdate-sh to work on OS/2.
1158 * Don't byte-compile elisp files when ELCFILES is set empty.
1159 (this documented feature was broken by 1.7.3)
1160 * Diagnose trailing backslashes on last line of Makefile.am.
1161 * Diagnose whitespace following trailing backslashes.
1162 * Multiple tests are now correctly supported in DEJATOOL. (PR/388)
1163 * Fix rebuilt rules for AC_CONFIG_FILES([Makefile:Makefile.in:Makefile.bot])
1165 * `make install' will build `BUILT_SOURCES' first.
1166 * Minor documentation fixes.
1168 Bugs fixed in 1.7.3:
1169 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1170 * Query distutils for `pythondir' and `pythonexecdir', instead of
1171 using an hardcoded path. This should allow builds on 64-bit
1172 distributions that usually use lib64/ instead of lib/.
1173 * AM_PATH_PYTHON will also search for python2.3.
1174 * elisp files are now built all at once instead of one by one. Besides
1175 incurring a speed-up, this is required to support interdependent elisp files.
1176 * Support for DJGPP:
1177 - `make distcheck' will now work in `_inst/' and `_build' instead
1178 of `=inst/' and `=build/'
1179 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1180 - install/uninstall `*.i[0-9][0-9]'-style info files
1181 - more changes that affect only the Automake package (not its output)
1182 * Fix some incompatibilities with upcoming perl-5.10.
1183 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1184 PACKAGE and VERSION.
1186 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1187 is troublesome with gcc and Solaris compilers. (PR/385)
1188 - makedepend mode: work with Libtool. (PR/385 too)
1190 * better support for unusual gettext setups, such as multiple po/ directories
1192 - Flag missing po/ and intl/ directories as warnings, not errors.
1193 - Disable these warnings if po/ does not exist.
1194 * Noteworthy manual updates:
1196 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1198 - Document `AM_YFLAGS = -d'. (PR/382)
1200 Bugs fixed in 1.7.2:
1201 * Fix installation and uninstallation of Info files built in subdirectories.
1202 * Do not run `./configure --with-included-gettext' during `make distcheck'
1203 if AM_GNU_GETTEXT([external]) is used.
1204 * Correctly uninstall renamed man pages.
1205 * Do not strip escaped newline in variables defined in one condition
1206 and augmented in another condition.
1207 * Fix ansi2knr rules for LIBOBJS sources.
1208 * Clean all known Texinfo index files, not only those which appear to
1209 be used, because we cannot know wich indexes are used in included files.
1210 (PR/375, Debian Bug #168671)
1211 * Honor only the first @setfilename seen in a Texinfo file.
1212 * Treat "required file X not found" diagnostics as errors (exit status 1).
1213 * Don't complain that a required file is not found when it is a Makefile
1215 * Don't use single suffix inference rules when building `.info'-less
1216 Info files, for the sake of Solaris make.
1217 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1218 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1219 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1220 * Fix building of deansified files from subdirectories. (PR/370)
1221 * Add missing `fi' in the .c->.obj rules.
1222 * Improve install-sh to work even when names contain spaces or certain
1223 (but not all) shell metachars.
1224 * Fix the following spurious failures in the test suite:
1225 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1226 * Noteworthy manual updates:

1228 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1230 Bugs fixed in 1.7.1:
1231 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1233 * Aclocal should now recognize macro names containing parentheses, e.g.
1234 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1235 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1237 * Install Python files even if they were built. (PR/369)
1238 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1239 version might not be defined in the latter. (PR/358)
1240 * Reorder arguments passed to a couple of commands, so things works
1241 when POSIXLY_CORRECT=1.
1242 * Fix a regex that can cause Perl to segfault on large input.
1244 * Fix distribution of packages that have some sources defined conditionally,
1245 as in the `Conditional compilation using Automake conditionals' example
1247 * Fix spurious test suite failures on IRIX.
1248 * Don't report a required variable as undefined if it has been
1249 defined conditionally for the "right" conditions.
1250 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1251 `make distcheck' fails.
1252 * Fix distribution of included Makefile fragment, so we don't create
1253 spurious directories in the distribution. (PR/366)
1254 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1257 * Autoconf 2.54 is required.
1258 * `aclocal' and `automake' will no longer warn about obsolete
1259 configure macros. This is done by `autoconf -Wobsolete'.
1260 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1261 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1262 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1263 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1264 `configure.ac' for you.
1265 * Support for per-program and per-library `_CPPFLAGS'.
1266 * New `ctags' target (builds CTAGS files).
1267 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1268 (see `automake --help' or the manual for a list of them).
1269 * Honor the WARNINGS environment variable.
1270 * Omit the call to depcomp when using gcc3: call the compiler directly.
1271 * A new option, std-options, tests that programs support --help and --version
1272 when `make installcheck' is run. This is enabled by --gnits.
1273 * Texinfo rules now support the `ps' and `pdf' targets.
1274 * Info files are now created in the build directory, not the source directory.
1275 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1277 * `make distcheck' will enforce DESTDIR support by attempting
1279 * `+=' can be used in conditionals, even if the augmented variable
1280 was defined for another condition.
1281 * Makefile fragments (inserted with `include') are always distributed.
1282 * Use Autoconf's --trace interface to inspect configure.ac and get
1283 a more accurate view of it.
1284 * Add support for extending aclocal's default macro search path
1285 using a `dirlist' file within the aclocal directory.
1286 * automake --output-dir is deprecated.
1287 * The part of the distcheck target that checks whether uninstall actually
1288 removes all installed files has been moved in a separate target,
1289 distuninstallcheck, so it can be overridden easily.
1293 * Support for AM_INIT_GETTEXT([external])
1294 * Bug fixes, including:
1295 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1296 - nobase_ programs and scripts honor --program-transform correctly.
1297 - Erase configure.lineno during `make distclean'.
1298 - Erase YACC and LEX outputs during `make maintainer-clean'.
1301 * Many bug fixes, including:
1302 - Requiring the current version works.
1303 - Fix "$@" portability issues (for Zsh).
1304 - Fix output of dummy dependency files in presence of post-processed
1306 - Don't compute dependencies in background to avoid races with libtool.
1307 - Fix handling of _OBJECTS variables for targets sharing source variables.
1308 - Check dependency mode for Java when AM_PROG_GCJ is used.
1311 * automake --output-dir is deprecated
1312 * Many bug fixes, including:
1313 - Don't choke on AM_LDFLAGS definitions.
1314 - Clean libtool objects from subdirectories.
1315 - Allow configure variables with reserved suffix and unknown prefix
1316 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1317 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1320 * Autoconf 2.52 is required.
1321 * automake no longer run libtoolize.
1322 This is the job of autoreconf (from GNU Autoconf).
1323 * `dist' generates all the archive flavors, as did `dist-all'.
1324 * `dist-gzip' generates the Gzip tar file only.
1325 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1326 explosion. Makefile.in's keep a reasonable size.
1327 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1328 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1330 * `#line' of Lex and Yacc files are properly set.
1331 * EXTRA_DIST can contain generated directories.
1332 * Support for dot-less extensions in suffix rules.
1333 * The part of the distcheck target that checks whether distclean actually
1334 cleans all built files has been moved in a separate target, distcleancheck,
1335 so it can be overridden easily.
1336 * `make distcheck' will pass additional options defined in
1337 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1338 * Fixed CDPATH portability problems, in particular for MacOS X.
1339 * Fixed handling of nobase_ targets.
1340 * Fixed support of implicit rules leading to .lo objects.
1341 * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON
1342 * Added uninstall-hook target
1343 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1344 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1345 (Note that "pkgname" is not "tarname", see the manual for details.)
1346 It is also possible to pass a list of global Automake options as
1347 first argument to this new form of AM_INIT_AUTOMAKE.
1348 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1349 to be a real assembler.
1350 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1351 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1352 * aclocal and automake are also installed with the version number
1353 appended, and some of the install directory names have changed.
1354 This lets you have multiple versions installed simultaneously.
1355 * Support for parsers and lexers in subdirectories.
1358 * Support for `configure.ac'.
1359 * Support for `else COND', `endif COND' and negated conditions `!COND'.

1381 * Can now put `.' in SUBDIRS to control build order
1382 * `include' command and `+=' support for macro assignment
1383 * Dependency tracking no long susceptible to deleted header file problem
