3 * WARNING: Future backward-incompatibilities!
5 - The support for the "obscure" multilib feature has been deprecated,
6 and will be moved out of the automake core in the next major Automake
9 - The support for ".log -> .html" conversion and the check-html and
10 recheck-html targets will be removed in the next major Automake
13 - The `lzma' compression format for distribution archives has been
14 deprecated in favor of `xz' and `lzip', and will be removed in the
15 next major Automake release (1.12).
17 - The Automake support for automatic de-ANSI-fication will be removed in
18 the next major Automake release (1.12).
20 - The `--acdir' option of aclocal is deprecated, and will probably be
21 removed in the next major Automake release (1.12).
23 - The exact order in which the directories in the aclocal macro
24 search path are looked up is probably going to be changed in the
25 next Automake release (1.12).
27 - The obsolescent AM_WITH_REGEX macro has been deprecated (since the
28 GNU rx library has been decommissioned), and will be removed in the
29 next major Automake release (1.12).
33 - The `--acdir' option is deprecated. Now you should use the new options
34 `--automake-acdir' and `--system-acdir' instead.
36 - The `ACLOCAL_PATH' environment variable is now interpreted as a
37 colon-separated list of additional directories to search after the
38 automake internal acdir (by default ${prefix}/share/aclocal-APIVERSION)
39 and before the system acdir (by default ${prefix}/share/aclocal).
41 * Miscellaneous changes:
43 - Automatic dependency tracking now works also with the IBM XL C/C++
44 compilers, thanks to the new new depmode 'xlc'.
46 - Automake's own build system is more silent by default, making use of
47 the 'silent-rules' option.
49 - The master copy of the `gnupload' script is now maintained in gnulib,
52 - The `missing' script doesn't try to wrap calls to `tar' anymore.
54 - "make dist" doesn't wrap `tar' invocations with the `missing' script
55 anymore. Similarly, the obsolescent variable `$(AMTAR)' (which you
56 shouldn't be using BTW ;-) does not invoke the missing script anymore
57 to wrap tar, but simply invokes the `tar' program itself.
59 - "make dist" can now create lzip-compressed tarballs.
61 - In the Automake info documentation, the Top node and the nodes about
62 the invocation of the automake and aclocal programs have been renamed;
63 now, calling "info automake" will open the Top node, while calling
64 "info automake-invocation" and "info aclocal-invocation" will access
65 the nodes about the invocation of respectively automake and aclocal.
67 - Automake is now distributed as a gzip-compressed and an xz-compressed
68 tarball. Previously, bzip2 was used instead of xz.
70 - The last relics of Python 1.5 support have been removed from the
73 - The `lzma' compression scheme and associated automake option `dist-lzma'
74 is obsoleted by `xz' and `dist-xz' due to upstream changes.
76 - You may adjust the compression options used in dist-xz and dist-bzip2.
77 The default is now merely -e for xz, but still -9 for bzip; you may
78 specify a different level via the XZ_OPT and BZIP2 envvars respectively.
79 E.g., "make dist-xz XZ_OPT=-7" or "make dist-bzip2 BZIP2=-5"
81 - The `compile' script now converts some options for MSVC for a better
82 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
84 - The py-compile script now accepts empty arguments passed to the options
85 `--destdir' and `--basedir', and complains about unrecognized options.
86 Moreover, a non-option argument or a special `--' argument terminates
89 - A developer that needs to pass specific flags to configure at "make
90 distcheck" time can now, and indeed is advised to, do so by defining
91 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
92 instead of the old DISTCHECK_CONFIGURE_FLAGS.
93 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
94 user; still, the old Makefile.am files that used to define it will
95 still continue to work as before.
97 - New macro AM_PROG_AR that looks for an archiver and wraps it in the new
98 'ar-lib' auxiliary script if the selected archiver is Microsoft lib.
99 This new macro is required for LIBRARIES and LTLIBRARIES when automake
100 is run with -Wextra-portability (or -Wall) and -Werror.
102 - When using DejaGnu-based testsuites, the user can extend the `site.exp'
103 file generated by automake-provided rules by defining the special make
104 variable `$(EXTRA_DEJAGNU_SITE_CONFIG)'.
106 - The `install-info' rule can now be instructed not to create/update
107 the `${infodir}/dir' file, by exporting the new environment variable
108 `AM_UPDATE_INFO_DIR' to the value "no".
110 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES
111 and adds them to the normal list of dependencies, but without
112 overwriting the foo_DEPENDENCIES variable, which is normally computed
115 - The 'ar-lib' script now ignores the "s" (symbol index) and "S" (no
116 symbol index) modifiers as well as the "s" action, as the symbol index
117 is created unconditionally by Microsoft lib. Also, the "q" (quick)
118 action is now a synonym for "r" (replace). Also, the script has been
119 ignoring the "v" (verbose) modifier already since Automake 1.11.3.
121 - When the 'compile' script is used to wrap MSVC, it now accepts an
122 optional space between the -I, -L and -l options and their respective
123 arguments, for better POSIX compliance.
125 - If "aclocal --install" is used, and the first directory specified with
126 '-I' is non-existent, aclocal will now create it before trying to copy
129 Bugs fixed in 1.11.0a:
131 * Bugs introduced by 1.11.2:
133 - Automake now correctly recognizes the prefix/primary combination
134 `pkglibexec_SCRIPTS' as valid.
136 - A definition of 'noinst_PYTHON' before 'python_PYTHON' (or similar)
137 don't cause spurious failures upon "make install" anymore.
139 * Bugs introduced by 1.11:
141 - The parallel-tests harness doesn't trip anymore on sed implementations
142 with stricter limits on the length of input lines (problem seen at
145 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
146 trailing white space in the test list (`TESTS = foo $(EMPTY)'), and
147 does not report spurious successes when used with concurrent FreeBSD
148 make (e.g., "make check -j3").
150 - When the parallel-tests driver is in use, automake now explicitly
151 rejects invalid entries and conditional contents in TEST_EXTENSIONS,
152 instead of issuing confusing and apparently unrelated error messages
153 (e.g., "non-POSIX variable name", "bad characters in variable name",
154 or "redefinition of TEST_EXTENSIONS), or even, in some situations,
155 silently producing broken `Makefile.in' files.
157 - The `silent-rules' option now truly silences all compile rules, even
158 when dependency tracking is disabled. Also, when `silent-rules' is
159 not used, `make' output no longer contains spurious backslash-only
160 lines, thus once again matching what Automake did before 1.11.
162 - The `silent-rules' option now generates working makefiles even for
163 the uncommon `make' implementations that do not support the
164 nested-variables extension to POSIX 2008. For such `make'
165 implementations, whether a build is silent is determined at
166 configure time, and cannot be overridden at make time with
167 `make V=0' or `make V=1'.
169 - The AM_COND_IF macro also works if the shell expression for the conditional
170 is no longer valid for the condition.
172 * Long-standing bugs:
174 - An empty declaration of a "foo_PRIMARY" don't cause anymore the
175 generated install rules to create an empty $(foodir) directory;
176 for example, if Makefile.am contains something like:
180 pkglibexec_SCRIPTS += bar.sh
183 the $(pkglibexec) directory will not be created upon "make install".
185 - It is now possible for a foo_SOURCES variable to hold Vala sources
186 together with C header files, as well as with sources and headers for
187 other supported languages (e.g., C++). Previously, only mixing C and
188 Vala sources was supported.
190 - Vala support now works better in VPATH setups.
192 - The "deleted header file problem" for *.am files is avoided by stub
193 rules. This allows `make' to trigger a rerun of `automake' also if
194 some previously needed `.am' file has been removed.
196 - "make distcheck" now correctly complains also when "make uninstall"
197 leaves one and only one file installed in $(prefix).
199 - A "make uninstall" issued before a "make install", or after a mere
200 "make install-data" or a mere "make install-exec" does not spuriously
203 - Automake now warns about more primary/directory invalid combinations,
204 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
206 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
207 even if the `--prefix' argument pointed outside of a system directory.
208 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
209 `get_python_lib' function if it points outside the configured prefix,
210 unless the `--prefix' argument was either `/usr' or below `/System'.
212 - The testsuite does not try to change the mode of `ltmain.sh' files from
213 a Libtool installation (symlinked to test directories) any more.
215 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
216 tools are preferred in a cross-compile setup.
218 - Several scripts and the parallel-tests testsuite driver now exit with
219 the right exit status upon receiving a signal.
221 - A per-Makefile.am setting of -Werror does not erroneously carry over
222 to the handling of other Makefile.am files.
224 - The order of Yacc and Lex flags is now consistent with that of other
225 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
226 $(LFLAGS), so that the user variables override the developer variables.
228 - Rules generated by Automake now try harder not to change any files when
229 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
230 Yacc source files and the rule to update config.h.
232 - The code for automatic dependency tracking works around a Solaris
233 make bug triggered by sources containing repeated slashes when the
234 `subdir-objects' option was used.
236 - The parallel-tests driver no longer produces erroneous results with
237 Tru64/OSF 5.1 sh upon unreadable log files.
239 - The makedepend and hp depmodes now work better with VPATH builds.
241 - Java sources specified with check_JAVA are no longer compiled for
242 "make all", but only for "make check".
244 - An usage like "java_JAVA = foo.java" will now cause Automake to warn
245 and error out if `javadir' is undefined, instead of silently producing
246 a broken Makefile.in.
248 - aclocal and automake now honour the configure-time definitions of
249 AUTOCONF and AUTOM4TE when they spawn autoconf or autom4te processes.
251 - The `install-info' recipe no longer tries to guess whether the
252 `install-info' program is from Debian or from GNU, and adaptively
253 change its behaviour; this has proven to be frail and easy to
258 * Version requirements:
260 - Autoconf 2.62 or greater is required.
262 * Changes to aclocal:
264 - The autoconf version check implemented by aclocal in aclocal.m4
265 (and new in Automake 1.10) is degraded to a warning. This helps
266 in the common case where the Autoconf versions used are compatible.
268 * Changes to automake:
270 - The automake program can run multiple threads for creating most
271 Makefile.in files concurrently, if at least Perl 5.7.2 is available
272 with interpreter-based threads enabled. Set the environment variable
273 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
274 enable this experimental feature.
276 * Changes to Libtool support:
278 - Libtool generic flags are now passed to the install and uninstall
281 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
282 config.lt is removed correctly now.
286 - subdir-object mode works now with Fortran (F77, FC, preprocessed
287 Fortran, and Ratfor).
289 - For files with extension .f90, .f95, .f03, or .f08, the flag
290 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
292 - Files with extension .sx are also treated as preprocessed assembler.
294 - The default source file extension (.c) can be overridden with
295 AM_DEFAULT_SOURCE_EXT now.
297 - Python 3.0 is supported now, Python releases prior to 2.0 are no
300 - AM_PATH_PYTHON honors python's idea about the site directory.
302 - There is initial support for the Vala programming language, when using
305 * Miscellaneous changes:
307 - Automake development is done in a git repository on Savannah now, see
309 http://git.sv.gnu.org/gitweb/?p=automake.git
311 A read-only CVS mirror is provided at
313 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
314 checkout -d automake HEAD
316 - "make dist" can now create xz-compressed tarballs,
317 as well as (deprecated?) lzma-compressed tarballs.
319 - `automake --add-missing' will by default install the GPLv3 file as
320 COPYING if it is missing. It will also warn that the license file
321 should be added to source control. Note that Automake will never
322 overwrite an existing COPYING file, even when the `--force-missing'
325 - The manual is now distributed under the terms of the GNU FDL 1.3.
327 - Automake ships and installs man pages for automake and aclocal now.
329 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
331 - install-sh supports -C, which does not update the installed file
332 (and its time stamps) if the contents did not change.
334 - The `gnupload' script has been revamped.
336 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
338 - The targets `install' and `uninstall' are more efficient now, in that
339 for example multiple files from one Automake variable such as
340 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
341 invocation if they do not have to be renamed.
343 Both install and uninstall may sometimes enter (`cd' into) the target
344 installation directory now, when no build-local scripts are used.
346 Both install and uninstall do not fail anymore but do nothing if an
347 installation directory variable like `bindir' is set to the empty string.
349 For built-in rules, `make install' now fails reliably if installation
350 of a file failed. Conversely, `make uninstall' even succeeds when
351 issued multiple times.
353 These changes may need some adjustments from users: For example,
354 some `install' programs refuse to install multiple copies of the
355 same file in one invocation, so you may need to remove duplicate
356 entries from file lists.
358 Also, within one set of files, say, nobase_data_DATA, the order of
359 installation may be changed, or even unstable among different hosts,
360 due to the use of associative arrays in awk. The increased use of
361 awk matches a similar move in Autoconf to provide for better scaling.
363 Further, most undocumented per-rule install command variables such as
364 binSCRIPT_INSTALL have been removed because they are not needed any
365 more. Packages which use them should be using the appropriate one of
366 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
367 counterpart, depending on the type of files and the need for automatic
368 target directory creation.
370 - The "deleted header file problem" for *.m4 files is avoided by
371 stub rules. This allows `make' to trigger a rerun of `aclocal'
372 also if some previously needed macro file has been removed.
374 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
375 an otherwise up to date tree.
377 - The `color-tests' option causes colored test result output on terminals.
379 - The `parallel-tests' option enables a new test driver that allows for
380 parallel test execution, inter-test dependencies, lazy test execution
381 for unit-testing, re-testing only failed tests, and formatted result output
382 as RST (reStructuredText) and HTML. Enabling this option may require some
383 changes to your test suite setup; see the manual for details.
385 - The `silent-rules' option enables Linux kernel-style silent build output.
386 This option requires the widely supported but non-POSIX `make' feature
387 of recursive variable expansion, so do not use it if your package needs
388 to build with `make' implementations that do not support it.
390 To enable less verbose build output, the developer has to use the Automake
391 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
392 macro. The user may then set the default verbosity by passing the
393 `--enable-silent-rules' option to `configure'. At `make' run time, this
394 default may be overridden using `make V=0' for less verbose, and `make V=1'
395 for backward-compatible verbose output.
397 - New prefix `notrans_' for manpages which should not be transformed
398 by --program-transform.
400 - New macro AM_COND_IF for conditional evaluation and conditional
403 - For AC_CONFIG_LINKS, if source and destination are equal, do not
404 remove the file in a non-VPATH build. Such setups work with Autoconf
407 - AM_MAINTAINER_MODE now allows for an optional argument specifying
410 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
411 useful especially for multi-line values.
413 - Automake's early configure-time sanity check now diagnoses an
414 unsafe absolute source directory name and makes configure fail.
416 - The Automake macros and rules cope better with whitespace in the
417 current directory name, as long as the relative path to `configure'
418 does not contain whitespace. To this end, the values of `$(MISSING)'
419 and `$(install_sh)' may contain suitable quoting, and their expansion
420 might need `eval'uation if used outside of a makefile. These
421 undocumented variables may be used in several documented macros such
422 as $(AUTOCONF) or $(MAKEINFO).
426 * Long-standing bugs:
428 - Fix aix dependency tracking for libtool objects.
430 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
431 unnecessary use of the `compile' script.
433 - For nobase_*_LTLIBRARIES with nonempty directory components, the
434 correct `-rpath' argument is used now.
436 - `config.status --file=Makefile depfiles' now also works with the
437 extra quoting used internally by Autoconf 2.62 and newer
438 (it used to work only without the `--file=' bit).
440 - The `missing' script works better with versioned tool names.
442 - Semantics for `missing help2man' have been revamped:
444 Previously, if `help2man' was not present, `missing help2man' would have
445 the following semantics: if some man page was out of date but present, then
446 a warning would be printed, but the exit status was 0. If the man page was
447 not present at all, then `missing' would create a replacement man page
448 containing an error message, and exit with a status of 2. This does not play
449 well with `make': the next run will see this particular man page as being up
450 to date, and will only error out on the next generated man page, if any;
451 repeat until all pages are done. This was not desirable.
453 These are the new semantics: if some man page is not present, and help2man
454 is not either, then `missing' will warn and generate the replacement page
455 containing the error message, but exit successfully. However, `make dist'
456 will ensure that no such bogus man pages are packaged into a tarball.
458 - Targets provided by automake behave better with `make -n', in that they
459 take care not to create files.
461 - `config.status Makefile... depfiles' works fine again in the presence of
462 disabled dependency tracking.
464 - The default no-op recursive rules for these targets also work with BSD make
465 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
467 - `make distcheck' works also when both a directory and some file below it
468 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
470 - Texinfo dvi, ps, pdf, and html output files are not removed upon
471 `make mostlyclean' any more; only the LaTeX by-products are.
473 - Renamed objects also work with the `subdir-objects' option and
474 source file languages which Automake does not know itself.
476 - `automake' now correctly complains about variable assignments which are
477 preceded by a comment, extend over multiple lines with backslash-escaped
478 newlines, and end in a comment sign. Previous versions would silently
479 and wrongly ignore such assignments completely.
481 * Bugs introduced by 1.10:
483 - Fix output of dummy dependency files in presence of post-processed
484 Makefile.in's again, but also cope with long lines.
486 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
487 that have been declared as programs in the same Makefile.
488 This is for consistency with the analogous change to TESTS in 1.10.
490 - Fix order of standard includes to again be `-I. -I$(srcdir)',
491 followed by directories containing config headers.
495 * Version requirements:
497 - Autoconf 2.60 or greater is required.
499 - Perl 5.6 or greater is required.
501 * Changes to aclocal:
503 - aclocal now also supports -Wmumble and -Wno-mumble options.
505 - `dirlist' entries (for the aclocal search path) may use shell
506 wildcards such as `*', `?', or `[...]'.
508 - aclocal supports an --install option that will cause system-wide
509 third-party macros to be installed in the local directory
510 specified with the first -I flag. This option also uses #serial
511 lines in M4 files to upgrade local macros.
513 The new aclocal options --dry-run and --diff help to review changes
514 before they are installed.
516 - aclocal now outputs an autoconf version check in aclocal.m4 in
517 projects using automake.
519 For a few years, automake and aclocal have been calling autoconf
520 (or its underlying engine autom4te) to accurately retrieve the
521 data they need from configure.ac and its siblings. Doing so can
522 only work if all autotools use the same version of autoconf. For
523 instance a Makefile.in generated by automake for one version of
524 autoconf may stop working if configure is regenerated with another
525 version of autoconf, and vice versa.
527 This new version check ensures that the whole build system has
528 been generated using the same autoconf version.
530 * Support for new Autoconf macros:
532 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
534 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
535 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
536 in different directories. However, only one instance of such a
537 library objects directory is supported.
539 * Change to Libtool support:
541 - Libtool generic flags (those that go before the --mode=MODE option)
542 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
544 * Yacc and Lex changes:
546 - The rebuild rules for distributed Yacc and Lex output will avoid
547 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
550 - ylwrap is now always used for lex and yacc source files,
551 regardless of whether there is more than one source per directory.
555 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
556 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
557 tracking, unlike non-preprocessed assembler (*.s).
559 - subdir-object mode works now with Assembler. Automake assumes
560 that the compiler understands `-c -o'.
562 - Preprocessed assembler (*.S) compilation now also honors
563 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
565 - Improved support for Objective C:
566 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
567 - A new section of the manual documents the support.
569 - New support for Unified Parallel C:
570 - AM_PROG_UPC looks for a UPC compiler.
571 - A new section of the manual documents the support.
573 - Per-target flags are now correctly handled in link rules.
575 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
576 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
577 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
578 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
580 The fix for compiler flags (i.e., using maude_CFLAGS instead of
581 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
582 is expected to work (and actually works during compilation).
584 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
585 "in addition to" breaks backward compatibility with older versions.
586 If your package used both variables, as in
588 AM_LDFLAGS = common flags
590 a_LDFLAGS = more flags
593 and assumed *_LDFLAGS would sum up, you should rewrite it as
595 AM_LDFLAGS = common flags
597 a_LDFLAGS = $(AM_LDFLAGS) more flags
600 This new behavior of *_LDFLAGS is more coherent with other
601 per-target variables, and the way *_LDFLAGS variables were
602 considered internally.
604 * New installation targets:
606 - New targets mandated by GNU Coding Standards:
611 By default they will only install Texinfo manuals.
612 You can customize them with *-local variants:
618 - The undocumented recursive target `uninstall-info' no longer exists.
619 (`uninstall' is in charge of removing all possible documentation
620 flavors, including optional formats such as dvi, ps, or info even
621 when `no-installinfo' is used.)
623 * Miscellaneous changes:
625 - Automake no longer complains if input files for AC_CONFIG_FILES
626 are specified using shell variables.
628 - clean, distribution, or rebuild rules are normally disabled for
629 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
630 AC_CONFIG_LINK specified using shell variables. However, if these
631 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
632 be able to output rules anyway.
633 (See the Automake documentation for AC_CONFIG_FILES.)
635 - $(EXEEXT) is automatically appended to filenames of TESTS
636 that have been declared as programs in the same Makefile.
637 This is mostly useful when some check_PROGRAMS are listed in TESTS.
639 - `-Wportability' has finally been turned on by default for `gnu' and
640 `gnits' strictness. This means, automake will complain about %-rules
641 or $(GNU Make functions) unless you switch to `foreign' strictness or
642 use `-Wno-portability'.
644 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
645 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
646 $(mkdir_p) variable is still defined (to the same value as
647 $(MKDIR_P)) but should be considered obsolete. If you are using
648 $(mkdir_p) in some of your rules, please plan to update them to
649 $(MKDIR_P) at some point.
651 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
652 They still work in this release, but may be withdrawn in a future one.
654 - Inline compilation rules for gcc3-style dependency tracking are
657 - Automake installs a "Hello World!" example package in $(docdir).
658 This example is used throughout the new "Autotools Introduction"
659 chapter of the manual.
663 * Makefile.in bloat reduction:
665 - Inference rules are used to compile sources in subdirectories when
666 the `subdir-objects' option is used and no per-target flags are
667 used. This should reduce the size of some projects a lot, because
668 Automake used to output an explicit rule for each such object in
671 - Automake no longer outputs three rules (.o, .obj, .lo) for each
672 object that must be built with explicit rules. It just outputs
673 the rules required to build the kind of object considered: either
674 the two .o and .obj rules for usual objects, or the .lo rule for
677 * Change to Libtool support:
679 - Libtool tags are used with libtool versions that support them.
680 (I.e., with Libtool 1.5 or greater.)
682 - Automake is now able to handle setups where a libtool library is
683 conditionally installed in different directories, as in
686 lib_LTLIBRARIES = liba.la
688 pkglib_LTLIBRARIES = liba.la
690 liba_la_SOURCES = ...
692 * Changes to aclocal:
694 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
695 really evaluated, before it decides to include them in aclocal.m4.
696 This solves nasty problems with conditional redefinitions of
697 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
698 *.m4 files to be included in any project using these macros.
699 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
700 most famous instance of this bug.)
702 - Do not complain about missing conditionally AC_REQUIREd macros
703 that are not actually used. In 1.8.x aclocal would correctly
704 determine which of these macros were really needed (and include
705 only these in the package); unfortunately it would also require
706 all of them to be present in order to run. This created
707 situations were aclocal would not work on a tarball distributing
708 all the macros it uses. For instance running aclocal on a project
709 containing only the subset of the Gettext macros in use by the
710 project did not work, because gettext conditionally requires other
713 * Portability improvements:
715 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
716 tar-pax. The new option filename-length-max=99 helps diagnosing
717 filenames that are too long for tar-v7. (PR/414)
719 - Variables aumented with `+=' are now automatically flattened (i.e.,
720 trailing backslashes removed) and then wrapped around 80 colummns
721 (adding trailing backslashes). In previous versions, a long series
727 would result in a single-line definition of VAR that could possibly
728 exceed the maximum line length of some make implementations.
730 Non-augmented variables are still output as they are defined in
735 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
736 Works the same as the old Fortran 77 implementation; just replace
737 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
738 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
740 - Support for conditional _LISP.
742 - Support for conditional -hook and -local rules (PR/428).
744 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
746 - Automake will not write any Makefile.ins after the first error it
747 encounters. The previous Makefile.ins (if any) will be left in
748 place. (Warnings will not prevent output, but remember they can
749 be turned into errors with -Werror.)
751 - The restriction that SUBDIRS must contain direct children is gone.
754 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
755 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
759 * Long-standing bugs:
761 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
762 so that `make distclean' and `make maintainer-clean' can work.
764 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
766 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
768 - Polish diagnostic when no input file is found.
772 * Long-standing bugs:
774 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
775 overridden by the user.
777 - Honor PATH_SEPARATOR in various places of the Automake package, for
780 - Adjust dependency tracking mode detection to ICC 8.0's new output.
783 - Fix install-sh so it can install the `mv' binary... using `mv'.
785 - Fix tru64 dependency tracking for libtool objects.
787 - Work around Exuberant Ctags when creating a TAGS files in a directory
788 without files to scan but with subdirectories to include.
790 * Bugs introduced by 1.8:
792 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
793 not defined in the same conditions as the _LDADD that uses it.
795 - Do not warn when JAVAROOT is overridden, this is legitimate.
799 * Long-standing bugs:
801 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
802 or any of the other *dir variables contain a space.
804 Please note that Automake does not and cannot support spaces in
805 filenames that are involved during the build. This change affects
806 only installation paths, so that `make install' does not bomb out
807 in packages configured with
808 ./configure --prefix '/c/Program Files'
810 - Fix the depfiles output so it works with GNU sed (<4.1) even when
811 POSIXLY_CORRECT is set.
813 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
814 since Autoconf 2.54, which defines LIBOBJS itself.
816 - Fix a potential (but unlikely) race condition in parallel elisp
817 builds. (Introduced in 1.7.3.)
819 - Do not assume that users override _DEPENDENCIES in all conditions
820 where Automake will try to define them.
822 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
823 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
826 This fix also affects the $(mkdir_p) variable defined since
827 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
828 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
830 - Secure temporary directory creation in `make distcheck'. (PR/413)
832 - Do not generate two build rules for `parser.h' when the
833 parser appears in two different conditionals.
835 - Work around a Solaris 8 /bin/sh bug in the test for dependency
836 checking. Usually ./configure will not pick this shell; so this
837 fix only helps cases where the shell is forced to /bin/sh.
839 * Bugs introduced by 1.8:
841 - In some situations (hand-written `m4_include's), aclocal would
842 call the `File::Spec->rel2abs' method, which was only introduced
843 in Perl 5.6. This new version reestablish support Perl 5.005.
845 It is likely that the next major Automake releases will require at
846 least Perl 5.6. Consider upgrading your development environment
847 if you are still using the five-year-old Perl 5.005.
849 - Automake would sometimes fail to define rules for targets listed
850 in variables defined in multiple conditions. For instance on
856 it would define only the `a.$(OBJEXT): a.c' rule and omit the
857 `b.$(OBJEXT): b.c' rule.
859 * New sections in manual:
861 - Third-Party Makefiles: how to interface third party Makefiles.
862 - Upgrading: upgrading packages to newer Automake versions.
863 - Multiple Outputs: handling tools that produce many outputs.
867 * A (well known) portability bug slipped in the changes made to
868 install-sh in Automake 1.8.1. The broken install-sh would refuse to
869 install anything on Tru64.
871 * Fix install rules for conditionally built python files. (This never
876 * Bugs introduced by 1.8:
878 - Fix Config.pm import error with old Perl versions (at least
879 5.005_03). One symptom is that aclocal could not find its macro
882 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
883 created by `make install' are always world readable, even if the
884 installer happens to have an overly restrictive umask (e.g. 077).
885 This was a mistake and has been reverted. There are at least two
886 reasons why we must not use `-m 0755':
887 - it causes special bits like SGID to be ignored,
888 - it may be too restrictive (some setups expect 775 directories).
890 - Fix aclocal to honor definitions located in files which have been
891 m4_included manually. aclocal 1.8 had been updated to check
892 m4_included files for new requirements, but forgot that these
893 m4_included files can also provide new definitions.
895 Note that if you have such a setup, we recommend you get rid of
896 it. In the past, there was a reason to m4_include files manually:
897 aclocal used to duplicate entire M4 files into aclocal.m4, even
898 files that were distributed. Some packages were therefore
899 m4_including the distributed file directly, and playing some
900 tricks to ensure aclocal would not copy that file to aclocal.m4,
901 in order to limit the amount of duplication. Since aclocal 1.8.x
902 will precisely output m4_includes for local M4 files, we recommend
903 that you clean up your setup, removing all manual m4_includes and
904 letting aclocal output them.
906 - Output detailed menus in the Info version if the Automake manual,
907 so that Emacs can locate the indexes.
909 - configure.ac and configure were listed twice in DIST_COMMON (an
910 internal variable where Automake lists configury files to
911 distribute). This was harmless, but unaesthetic.
913 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
914 This was an issue only in the Automake package itself, not in
917 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
918 DEST:SRC. This was wrong, as some packages do
919 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
922 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
923 argument. This caused two kinds of failures:
924 - Rules installing data in a conditionally defined directory
925 failed when that directory was undefined. In this case no
926 argument was supplied.
927 - `make installdirs' failed, because several directories were
928 passed to $(mkdir_p). This was an issue only on platform
929 were $(mkdir_p) is implemented with `install-sh -d'.
930 $(mkdir_p) as been changed to accept 0 or more arguments, as
933 * Long-standing bugs:
935 - Fix an unexpected diagnostic occurring when users attempt
936 to override some internal variables that Automake appends to.
938 - aclocal now scans configure.ac for macro definitions (PR/319).
940 - Fix a portability issue with OSF1/Tru64 Make. If a directory
941 distributes files which are outside itself (this usually occurs
942 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
943 from a parent package), then `make distcheck' fails due to an
944 optimization performed by OSF1/Tru64 Make in its VPATH handling.
945 (tests/subpkg2.test failure)
947 - Fix another portability issue with Sun and OSF1/Tru64 Make.
948 In a VPATH-build configuration, `make install' would install
949 nobase_ files to wrong locations.
951 - Fix a Perl `uninitialized value' diagnostic occurring when
952 automake complains that a Texinfo file does not have a
953 @setfilename statement.
955 - Erase config.status.lineno during `make distclean'. This file
956 can be created by config.status. Automake already knew about
957 configure.lineno, but forgot config.status.lineno.
959 - Distribute all files, even those which are built and installed
960 conditionally. This change affects files listed in conditionally
961 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
962 as well as those listed in conditionally defined dist_*_DATA,
963 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
965 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
966 doesn't conform to POSIX.
968 - Normalize help strings for configure variables and options added
973 - Check for python2.4 in AM_PATH_PYTHON.
975 * Spurious failures in test suite:
977 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
978 tests/ltconv.test: fix failures with CVS Libtool.
979 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
980 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
981 fix failures with old Texinfo versions.
987 - The NEWS file is more verbose.
991 - Autoconf 2.58 or greater is required.
995 - Default source file names in the absence of a _SOURCES declaration
996 are made by removing any target extension before appending `.c', so
997 to make the libtool module `foo.la' from `foo.c', you only need to
1000 lib_LTLIBRARIES = foo.la
1001 foo_la_LDFLAGS = -module
1003 For backward compatibility, foo_la.c will be used instead of
1004 foo.c if this file exists or is the explicit target of a rule.
1005 However -Wobsolete will warn about this deprecated naming.
1007 - AR's `cru' flags are now set in a global ARFLAGS variable instead
1008 of being hard-coded in each $(AR) invocation, so they can be
1009 substituted from configure.ac. This has been requested by people
1010 dealing with non-POSIX ar implementations.
1012 - New warning option: -Woverride. This will warn about any user
1013 target or variable definitions which override Automake
1016 - Texinfo rules back up and restore info files when makeinfo fails.
1018 - Texinfo rules now support the `html' target.
1019 Running this requires Texinfo 4.0 or greater.
1021 `html' is a new recursive target, so if your package mixes
1022 hand-crafted `Makefile.in's with Automake-generated
1023 `Makefile.in's, you should adjust the former to support (or
1024 ignore) this target so that `make html' recurses successfully. If
1025 you had a custom `html' rule in your `Makefile.am', it's better to
1026 rename it as `html-local', otherwise your rule will override
1027 Automake's new rule (you can check that by running `automake
1028 -Woverride') and that will stop the recursion to subdirectories.
1030 Last but not least, this `html' rule is declared PHONY, even when
1031 overridden. Fortunately, it appears that few packages use a
1032 non-PHONY `html' rule.
1034 - Any file which is m4_included from configure.ac will appear as a
1035 configure and Makefile.in dependency, and will be automatically
1038 - The rules for rebuilding Makefiles and Makefile.ins will now
1039 rebuild all Makefiles and all Makefile.ins at once when one of
1040 configure's dependencies has changed. This is considerably faster
1041 than previous implementations, where config.status and automake
1042 were run separately in each directory (this still happens when you
1043 change a Makefile.am locally, without touching configure.ac or
1044 friends). Doing this also solves a longstanding issue: these
1045 rebuild rules failed to work when adding new directories to the
1046 tree, forcing you to run automake manually.
1048 - For similar reasons, the rules to rebuild configure,
1049 config.status, and aclocal.m4 are now defined in all directories.
1050 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1051 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1052 should better define them in all directories. This is easily done
1053 using an AC_SUBST (make sure you prefix these dependencies with
1054 $(top_srcdir) since this variable will appear at different
1055 levels of the build tree).
1057 - aclocal will now use `m4_include' instead of copying local m4
1058 files into aclocal.m4. (Local m4 files are those you ship with
1059 your project, other files will be copied as usual.)
1061 Because m4_included files are automatically distributed, it means
1062 for most projects there is no point in EXTRA_DISTing the list of
1063 m4 files which are used. (You can probably get rid of
1064 m4/Makefile.am if you had one.)
1066 - aclocal will avoid touching aclocal.m4 when possible, so that
1067 Autom4te's cache isn't needlessly invalidated. This behavior can
1068 be switched off with the new `--force' option.
1070 - aclocal now uses Autoconf's --trace to detect macros which are
1071 actually used and will no longer include unused macros simply
1072 because they where mentioned. This was often the case for macros
1073 called conditionally.
1075 - New options no-dist and no-dist-gzip.
1077 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1078 py-compile, and ylwrap, now all understand --version and --help.
1080 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1081 links as part of the distclean target and including source files in
1084 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1085 argument. The latter can be used to override the default behavior
1086 (which is to abort).
1088 - Automake will exit with $? = 63 on version mismatch. (So does
1089 Autoconf 2.58) missing knows this, and in this case it will
1090 emulate the tools as if they were absent. Because older versions
1091 of Automake and Autoconf did not use this exit code, this change
1092 will only be useful in projects generated with future versions of
1095 - When using AC_CONFIG_FILES with multiple input files, Automake
1096 generates the first ".in" input file for which a ".am" exists.
1097 (Former versions would try to use only the first input file.)
1099 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1100 idiom to disable byte-compilation of lisp_LISP files, it is
1101 recommended that you switch to using lisp_DATA. Note that
1102 this is not strictly equivalent: lisp_DATA will install elisp
1103 files even if emacs is not installed, while *_LISP do not
1104 install anything unless emacs is found.
1106 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1107 available. This selection is achieved through the Makefile
1108 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1109 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1110 `$(install_sh) -m 0755 -d'.
1114 - Because `mkdir -p' is available on most platforms, and we can use
1115 `install-sh -d' when it is not, the use of the mkinstalldirs
1116 script is being phased out. `automake --add-missing' no longer
1117 installs it, and if you remove mkinstalldirs from your package,
1118 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1120 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1121 gettextize and autopoint will install it when needed. Automake
1122 will continue to define the $(mkinstalldirs) and to distribute
1123 mkinstalldirs when this script is in the source tree.
1125 - AM_PROG_CC_STDC is now empty. The content of this macro was
1126 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1127 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1128 renaming should be safe, even if you have to support several,
1129 versions of Automake, because AC_PROG_CC defines this variable
1130 since Autoconf 2.54.)
1132 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1133 variable to override the aclocal.m4 dependencies computed
1134 (inaccurately) by older versions of Automake. Because Automake
1135 now tracks configure's m4 dependencies accurately (see m4_include
1136 above), the use of ACLOCAL_M4_SOURCES should be considered
1137 obsolete and will be flagged as such when running `automake
1142 - Defining programs conditionally using Automake conditionals no
1143 longer leads to a combinatorial explosion. The following
1144 construct used to be troublesome when used with dozens of
1159 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1161 - Due to implementation constraints, previous versions of Automake
1162 proscribed multiple conditional definitions of some variables
1172 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1173 This restriction has been lifted, and these variables now
1174 support multiple conditional definitions as do other variables.
1176 - Cleanup the definitions of $(distdir) and $(top_distdir).
1177 $(top_distdir) now points to the root of the distribution
1178 directory created during `make dist', as it did in Automake 1.4,
1179 not to the root of the build tree as it did in intervening
1180 versions. Furthermore these two variables are now only defined in
1181 the top level Makefile, and passed to sub-directories when running
1184 - The --no-force option now correctly checks the Makefile.in's
1185 dependencies before deciding not to update it.
1187 - Do not assume that make files are called Makefile in cleaning rules.
1189 - Update .info files in the source tree, not in the build tree. This
1190 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1191 used to update these files in the build tree (previous versions did
1192 it in the source tree too), and it caused several problems, varying
1193 from mere annoyance to portability issues.
1195 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1196 when --add-missing and --force-missing are used. For backward
1197 compatibility --add-missing will continue to install COPYING (in
1198 `gnu' strictness) when none of these three files exist, but this
1199 use is deprecated: you should better choose a license yourself and
1200 install it once for all in your source tree (and in your code
1203 - Fix ylwrap so that it does not overwrite header files that haven't
1204 changed, as the inline rule already does.
1206 - User-defined rules override automake-defined rules for the same
1207 targets, even when rules do not have commands. This is not new
1208 (and was documented), however some of the automake-generated
1209 rules have escaped this principle in former Automake versions.
1210 Rules for the following targets are affected by this fix:
1212 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1213 info, info-am, install-data-am, install-exec-am, install-info,
1214 install-info-am, install-man, installcheck-am, maintainer-clean,
1215 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1216 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1218 Practically it means that an attempt to supplement the dependencies
1219 of some target, as in
1221 clean: my-clean-rule
1223 will now *silently override* the automake definition of the
1224 rule for this target. Running `automake -Woverride' will diagnose
1225 all such overriding definitions.
1227 It should be noted that almost all these targets support a *-local
1228 variant that is meant to supplement the automake-defined rule
1229 (See node `Extending' in the manual). The above rule should
1232 clean-local: my-clean-rule
1234 These *-local targets have been documented since at least
1235 Automake 1.2, so you should not fear the change if you have
1236 to support multiple automake versions.
1240 - The Automake manual is now distributed under the terms of the GNU FDL.
1242 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1244 - core dumps are no longer removed by the cleaning rules. There are
1245 at least three reasons for this:
1246 1. These files should not be created by any build step,
1247 so their removal do not fit any of the cleaning rules.
1248 Actually, they may be precious to the developer.
1249 2. If such file is created during a build, then it's clearly a
1250 bug Automake should not hide. Not removing the file will
1251 cause `make distcheck' to complain about its presence.
1252 3. Operating systems have different naming conventions for
1253 core dump files. A core file on one system might be a
1254 completely legitimate data file on another system.
1256 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1257 defined by Automake. This means that any definition in the
1258 environment will be used, unless overridden in the Makefile.am or
1259 on the command line. The old behavior, where these variables were
1260 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1261 AC_ARG_VARing each variable from configure.ac.
1263 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1264 documented. (The is not a new feature, these variables have
1265 been there since at least Automake 1.4.)
1267 Bugs fixed in 1.7.9:
1268 * Fix install-strip to work with nobase_ binaries.
1269 * Fix renaming of #line directives in ylwrap.
1270 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1272 Bugs fixed in 1.7.8:
1273 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1274 * Fix detection of Debian's install-info, broken since version 1.5.
1275 (Debian bug #213524).
1276 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1277 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1279 Bugs fixed in 1.7.7:
1280 * The implementation of automake's --no-force option is unreliable,
1281 so this option is ignored in this version. A real fix will appear in
1282 Automake 1.8. (Debian Bug #206299)
1283 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1284 argument is given. (PR/399)
1285 * Do not warn about leading `_' in variable names, even with -Wportability.
1286 * Support user redefinitions of TEXINFO_TEX.
1287 * depcomp: support AIX Compiler version 6.
1288 * Fix missing rebuilds during `make dist' with BSD make.
1289 (Could produce tarballs containing out-of-date files.)
1290 * Resurrect multilib support.
1291 * Noteworthy manual updates:
1292 - Extending aclocal: how to write m4 macros that won't trigger warnings
1294 - A Shared Library: Rewrite and split into subsections.
1296 Bugs fixed in 1.7.6:
1297 * Fix depcomp's icc mode for ICC 7.1.
1298 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1299 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1300 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1301 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1302 * Remove Latin-1 characters from elisp-comp.
1303 * Update the manual's @dircategory to match the Free Software Directory.
1305 Bugs fixed in 1.7.5:
1306 * Update install-sh's license to remove an advertising clause.
1307 (Debian bug #191717)
1308 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1309 that caused invalid Makefile.ins to be generated.
1310 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1311 * New FAQ entry: renamed objects.
1313 Bugs fixed in 1.7.4:
1314 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1315 the Emacs implementation)
1316 * Fix output of aclocal.m4 dependencies in subdirectories.
1317 * Use `mv -f' instead of `mv' in fastdep rules.
1318 * Upgrade mdate-sh to work on OS/2.
1319 * Don't byte-compile elisp files when ELCFILES is set empty.

1326 * `make install' will build `BUILT_SOURCES' first.
1327 * Minor documentation fixes.
1329 Bugs fixed in 1.7.3:
1330 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1331 * Query distutils for `pythondir' and `pythonexecdir', instead of
1332 using an hardcoded path. This should allow builds on 64-bit
1333 distributions that usually use lib64/ instead of lib/.
1334 * AM_PATH_PYTHON will also search for python2.3.
1335 * elisp files are now built all at once instead of one by one. Besides
1336 incurring a speed-up, this is required to support interdependent elisp files.
1337 * Support for DJGPP:
1338 - `make distcheck' will now work in `_inst/' and `_build' instead
1339 of `=inst/' and `=build/'
1340 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1341 - install/uninstall `*.i[0-9][0-9]'-style info files
1342 - more changes that affect only the Automake package (not its output)
1343 * Fix some incompatibilities with upcoming perl-5.10.
1344 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1345 PACKAGE and VERSION.
1347 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1348 is troublesome with gcc and Solaris compilers. (PR/385)
1349 - makedepend mode: work with Libtool. (PR/385 too)
1351 * better support for unusual gettext setups, such as multiple po/ directories
1353 - Flag missing po/ and intl/ directories as warnings, not errors.
1354 - Disable these warnings if po/ does not exist.
1355 * Noteworthy manual updates:
1357 - Document how AC_CONFIG_AUX_DIR interacts with missing files.
1359 - Document `AM_YFLAGS = -d'. (PR/382)
1361 Bugs fixed in 1.7.2:
1362 * Fix installation and uninstallation of Info files built in subdirectories.
1363 * Do not run `./configure --with-included-gettext' during `make distcheck'
1364 if AM_GNU_GETTEXT([external]) is used.
1365 * Correctly uninstall renamed man pages.
1366 * Do not strip escaped newline in variables defined in one condition
1367 and augmented in another condition.
1368 * Fix ansi2knr rules for LIBOBJS sources.
1369 * Clean all known Texinfo index files, not only those which appear to
1370 be used, because we cannot know wich indexes are used in included files.
1371 (PR/375, Debian Bug #168671)
1372 * Honor only the first @setfilename seen in a Texinfo file.
1373 * Treat "required file X not found" diagnostics as errors (exit status 1).
1374 * Don't complain that a required file is not found when it is a Makefile
1376 * Don't use single suffix inference rules when building `.info'-less
1377 Info files, for the sake of Solaris make.
1378 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1379 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1380 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1381 * Fix building of deansified files from subdirectories. (PR/370)
1382 * Add missing `fi' in the .c->.obj rules.
1383 * Improve install-sh to work even when names contain spaces or certain
1384 (but not all) shell metachars.
1385 * Fix the following spurious failures in the test suite:
1386 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1387 * Noteworthy manual updates:
1388 - Augment the section about BUILT_SOURCES.
1389 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1391 Bugs fixed in 1.7.1:
1392 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1394 * Aclocal should now recognize macro names containing parentheses, e.g.
1395 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1396 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1398 * Install Python files even if they were built. (PR/369)
1399 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1400 version might not be defined in the latter. (PR/358)
1401 * Reorder arguments passed to a couple of commands, so things works
1402 when POSIXLY_CORRECT=1.
1403 * Fix a regex that can cause Perl to segfault on large input.
1405 * Fix distribution of packages that have some sources defined conditionally,
1406 as in the `Conditional compilation using Automake conditionals' example
1408 * Fix spurious test suite failures on IRIX.
1409 * Don't report a required variable as undefined if it has been
1410 defined conditionally for the "right" conditions.
1411 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1412 `make distcheck' fails.
1413 * Fix distribution of included Makefile fragment, so we don't create
1414 spurious directories in the distribution. (PR/366)
1415 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1418 * Autoconf 2.54 is required.
1419 * `aclocal' and `automake' will no longer warn about obsolete
1420 configure macros. This is done by `autoconf -Wobsolete'.
1421 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1422 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1423 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1424 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1425 `configure.ac' for you.
1426 * Support for per-program and per-library `_CPPFLAGS'.
1427 * New `ctags' target (builds CTAGS files).
1428 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1429 (see `automake --help' or the manual for a list of them).
1430 * Honor the WARNINGS environment variable.
1431 * Omit the call to depcomp when using gcc3: call the compiler directly.
1432 * A new option, std-options, tests that programs support --help and --version
1433 when `make installcheck' is run. This is enabled by --gnits.
1434 * Texinfo rules now support the `ps' and `pdf' targets.
1435 * Info files are now created in the build directory, not the source directory.
1436 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1438 * `make distcheck' will enforce DESTDIR support by attempting
1440 * `+=' can be used in conditionals, even if the augmented variable
1441 was defined for another condition.
1442 * Makefile fragments (inserted with `include') are always distributed.
1443 * Use Autoconf's --trace interface to inspect configure.ac and get
1444 a more accurate view of it.
1445 * Add support for extending aclocal's default macro search path
1446 using a `dirlist' file within the aclocal directory.
1447 * automake --output-dir is deprecated.
1448 * The part of the distcheck target that checks whether uninstall actually
1449 removes all installed files has been moved in a separate target,
1450 distuninstallcheck, so it can be overridden easily.
1454 * Support for AM_INIT_GETTEXT([external])
1455 * Bug fixes, including:
1456 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1457 - nobase_ programs and scripts honor --program-transform correctly.
1458 - Erase configure.lineno during `make distclean'.
1459 - Erase YACC and LEX outputs during `make maintainer-clean'.
1462 * Many bug fixes, including:

1474 - Don't choke on AM_LDFLAGS definitions.
1475 - Clean libtool objects from subdirectories.
1476 - Allow configure variables with reserved suffix and unknown prefix
1477 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1478 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1481 * Autoconf 2.52 is required.
1482 * automake no longer run libtoolize.
1483 This is the job of autoreconf (from GNU Autoconf).
1484 * `dist' generates all the archive flavors, as did `dist-all'.
1485 * `dist-gzip' generates the Gzip tar file only.
1486 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1487 explosion. Makefile.in's keep a reasonable size.
1488 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1489 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1491 * `#line' of Lex and Yacc files are properly set.
1492 * EXTRA_DIST can contain generated directories.
1493 * Support for dot-less extensions in suffix rules.
1494 * The part of the distcheck target that checks whether distclean actually
1495 cleans all built files has been moved in a separate target, distcleancheck,
1496 so it can be overridden easily.
1497 * `make distcheck' will pass additional options defined in
1498 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1499 * Fixed CDPATH portability problems, in particular for MacOS X.
1500 * Fixed handling of nobase_ targets.
1501 * Fixed support of implicit rules leading to .lo objects.

1504 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1505 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1506 (Note that "pkgname" is not "tarname", see the manual for details.)
1507 It is also possible to pass a list of global Automake options as
1508 first argument to this new form of AM_INIT_AUTOMAKE.
1509 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1510 to be a real assembler.
1511 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1512 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
1513 * aclocal and automake are also installed with the version number
