5 - automake now generates silenced rules for texinfo outputs.
7 - The deprecated options `--output-dir', `--Werror' and `--Wno-error'
12 - New `cscope' target to build a cscope database for the source tree.
14 * Changes to Automake-generated testsuite harnesses:
16 - Test scripts that exit with status 99 to signal an "hard error" (e.g.,
17 and unexpected or internal error, or a failure to set up the test case
18 scenario) have their outcome reported as an 'ERROR' now. Previous
19 versions of automake reported such an outcome as a 'FAIL' (the only
20 difference with normal failures being that hard errors were counted
21 as failures even when the test originating them was listed in
24 - The testsuite summary displayed by the parallel-test harness has a
25 completely new format, that always list the numbers of passed, failed,
26 xfailed, xpassed, skipped and errored tests, even when these numbers
27 are zero (but using smart coloring when the color-tests option is in
30 - The default testsuite driver offered by the 'parallel-tests' option is
31 now implemented (partly at least) with the help of automake-provided
32 auxiliary scripts (e.g., `test-driver'), instead of relying entirely
33 on code in the generated Makefile.in.
34 This has two noteworthy implications. The first one is that projects
35 using the `parallel-tests' option should now either run automake with
36 the `--add-missing' option, or manually copy the `test-driver' script
37 into their tree. The second, and more important, implication is that
38 now, when the `parallel-tests' option is in use, TESTS_ENVIRONMENT can
39 not be used anymore to define a test runner, and the command specified
40 in LOG_COMPILER (and <ext>_LOG_COMPILER) must be a *real* executable
41 program or script. For example, this is still a valid usage (albeit
45 if test -n '$(STRICT_TESTS)'; then \
50 LOG_COMPILER = $(SHELL) $$maybe_errexit
52 while this is not anymore:
55 $(SHELL) `test -n '$(STRICT_TESTS_CHECKING)' && echo ' -e'`
60 run_with_perl_or_shell () \
62 if grep -q '^#!.*perl' $$1; then
68 LOG_COMPILER = run_with_per_or_shell
70 - The package authors can now use customary testsuite drivers within
71 the framework provided by the 'parallel-tests' testsuite harness.
72 Consistently with the existing syntax, this can be done by defining
73 special makefile variables `LOG_DRIVER' and `<ext>_LOG_DRIVER'.
75 - A new developer-reserved variable `AM_TESTS_FD_REDIRECT' can be used
76 to redirect/define file descriptors used by the test scripts.
78 - The parallel-tests harness generates now, in addition the `.log' files
79 holding the output produced by the test scripts, a new set of `.trs'
80 files, holding "metadata" derived by the execution of the test scripts;
81 among such metadata are the outcomes of the test cases run by a script.
83 - Initial and still experimental support for the TAP test protocol is
86 * WARNING: Future backward-incompatibilities!
88 - The Automake support for automatic de-ANSI-fication will be removed in
89 the next major Automake release (1.12).
91 * Miscellaneous changes:
93 - The `dist' and `dist-all' targets now can run compressors in parallel.
95 - The `lzma' compression scheme and associated automake option `dist-lzma'
96 is obsoleted by `xz' and `dist-xz' due to upstream changes.
98 - "make dist" can now create lzip-compressed tarballs.
100 - You may adjust the compression options used in dist-xz and dist-bzip2.
101 The default is still -9 for each, but you may specify a different
102 level via the XZ_OPT and BZIP2 envvars respectively. E.g.,
103 "make dist-xz XZ_OPT=-7" or "make dist-xz BZIP2=-5"
105 - Messages of types warning or error from `automake' and `aclocal' are now
106 prefixed with the respective type, and presence of -Werror is noted.
108 - The `compile' script now converts some options for MSVC for a better
109 user experience. Similarly, the new `ar-lib' script wraps Microsoft lib.
111 - Automake's early configure-time sanity check now tries to avoid sleeping
112 for a second, which slowed down cached configure runs noticeably. In that
113 case, it will check back at the end of the configure script to ensure that
114 at least one second has passed, to avoid time stamp issues with makefile
115 rules rerunning autotools programs.
117 - For programs and libraries, automake now detects EXTRA_foo_DEPENDENCIES and
118 adds them to the normal list of dependencies, but without overwriting the
119 foo_DEPENDENCIES variable, which is normally computed by automake.
121 - C source and header files derived from non-distributed Yacc sources are
122 now removed by "make clean", not only by "make maintainer-clean".
124 - A developer that needs to pass specific flags to configure at "make
125 distcheck" time can now, and indeed he's advised to, do so by defining
126 the developer-reserved makefile variable AM_DISTCHECK_CONFIGURE_FLAGS,
127 instead of the old DISTCHECK_CONFIGURE_FLAGS.
128 The DISTCHECK_CONFIGURE_FLAGS variable should now be reserved for the
129 user; still, the old Makefile.am files that used to define it should
130 still continue to work as before.
134 - Lots of minor bugfixes.
136 * Bugs introduced by 1.11:
138 - The `parallel-tests' test driver works around a GNU make 3.80 bug with
139 trailing white space in the test list (`TESTS = foo $(EMPTY)').
141 - The `silent-rules' option now also silences all compile rules if dependency
142 tracking is disabled. Also, when `silent-rules' is not used, the output from
143 `make' does not contain spurious extra lines with only a backslash in them
144 any more; it now again matches that from pre-1.11 Automake.
146 - The `dist-xz' option now uses `xz -9' for maximum compression.
148 - The AM_COND_IF macro also works if the shell expression for the conditional
149 is no longer valid for the condition.
151 * Long standing bugs:
153 - Automake now warns about more primary/directory invalid combinations,
154 such as "doc_LIBRARIES" or "pkglib_PROGRAMS".
156 - On Darwin 9, `pythondir' and `pyexecdir' pointed below `/Library/Python'
157 even if the `--prefix' argument pointed outside of a system directory.
158 AM_PATH_PYTHON has been fixed to ignore the value returned from python's
159 `get_python_lib' function if it points outside the configured prefix,
160 unless the `--prefix' argument was either `/usr' or below `/System'.
162 - The testsuite does not try to change the mode of `ltmain.sh' files from
163 a Libtool installation (symlinked to test directories) any more.
165 - AM_PROG_GCJ uses AC_CHECK_TOOLS to look for `gcj' now, so that prefixed
166 tools are preferred in a cross-compile setup.
168 - The distribution is tarred up with mode 755 now by the `dist*' targets.
169 This fixes a race condition where untrusted users could modify files
170 in the $(PACKAGE)-$(VERSION) distdir before packing if the toplevel
171 build directory was world-searchable. This is CVE-2009-4029.
173 - Several scripts as well as the parallel-tests testsuite driver now
174 exit with the right exit status upon receiving a signal.
176 - A per-Makefile.am setting of -Werror does not carry over to the
177 handling of other Makefile.am files any more.
179 - The order of Yacc and Lex flags is fixed to be consistent with other
180 languages: $(AM_YFLAGS) comes before $(YFLAGS), and $(AM_LFLAGS) before
181 $(LFLAGS), so that the user variables override the developer variables.
183 - Rules generated by Automake now try harder to not change any files when
184 `make -n' is invoked. Fixes include compilation of Emacs Lisp, Vala, or
185 Yacc source files and the rule to update config.h.
187 - The code for automatic dependency tracking works around a Solaris
188 make bug triggered by sources containing repeated slashes when the
189 `subdir-objects' option was used.
191 - Automake now detects the presence of the `-d' flag in the various
192 `*YFLAGS' variables even when their definitions involve indirections
193 through other variables, such as in:
195 AM_YFLAGS = $(foo_opts)
197 - Automake now complains if a `*YFLAGS' variable has any conditional
198 content, not only a conditional definition.
200 - Explicit enabling and/or disabling of Automake warning categories
201 through the `-W...' options now always takes precedence over the
202 implicit warning level implied by Automake strictness (foreign, gnu
203 or gnits), regardless of the order in which such strictness and
204 warning flags appear. For example, a setting like:
205 AUTOMAKE_OPTIONS = -Wall --foreign
206 will cause the warnings in category `portability' to be enabled, even
207 if those warnings are by default disabled in `foreign' strictness.
209 - The parallel-tests driver now does not produce erroneous results
210 with Tru64/OSF 5.1 sh upon unreadable log files any more.
212 - The makedepend and hp depmodes now works better with VPATH builds.
214 - Java sources specified with check_JAVA are not compiled anymore upon
215 "make all", but only upon "make check".
217 - Now aclocal and automake, when they've to spawn autoconf or autom4te
218 processes, honour the configure-time definitions of AUTOCONF and
223 * Version requirements:
225 - Autoconf 2.62 or greater is required.
227 * Changes to aclocal:
229 - The autoconf version check implemented by aclocal in aclocal.m4
230 (and new in Automake 1.10) is degraded to a warning. This helps
231 in the common case where the Autoconf versions used are compatible.
233 * Changes to automake:
235 - The automake program can run multiple threads for creating most
236 Makefile.in files concurrently, if at least Perl 5.7.2 is available
237 with interpreter-based threads enabled. Set the environment variable
238 AUTOMAKE_JOBS to the maximum number of threads to use, in order to
239 enable this experimental feature.
241 * Changes to Libtool support:
243 - Libtool generic flags are now passed to the install and uninstall
246 - distcheck works with Libtool 2.x even when LT_OUTPUT is used, as
247 config.lt is removed correctly now.
251 - subdir-object mode works now with Fortran (F77, FC, preprocessed
252 Fortran, and Ratfor).
254 - For files with extension .f90, .f95, .f03, or .f08, the flag
255 $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
257 - Files with extension .sx are also treated as preprocessed assembler.
259 - The default source file extension (.c) can be overridden with
260 AM_DEFAULT_SOURCE_EXT now.
262 - Python 3.0 is supported now, Python releases prior to 2.0 are no
265 - AM_PATH_PYTHON honors python's idea about the site directory.
267 - There is initial support for the Vala programming language, when using
270 * Miscellaneous changes:
272 - Automake development is done in a git repository on Savannah now, see
274 http://git.sv.gnu.org/gitweb/?p=automake.git
276 A read-only CVS mirror is provided at
278 cvs -d :pserver:anonymous@pserver.git.sv.gnu.org:/automake.git \
279 checkout -d automake HEAD
281 - "make dist" can now create xz-compressed tarballs,
282 as well as (deprecated?) lzma-compressed tarballs.
284 - `automake --add-missing' will by default install the GPLv3 file as
285 COPYING if it is missing. It will also warn that the license file
286 should be added to source control. Note that Automake will never
287 overwrite an existing COPYING file, even when the `--force-missing'
290 - The manual is now distributed under the terms of the GNU FDL 1.3.
292 - Automake ships and installs man pages for automake and aclocal now.
294 - New shorthand `$(pkglibexecdir)' for `$(libexecdir)/@PACKAGE@'.
296 - install-sh supports -C, which does not update the installed file
297 (and its time stamps) if the contents did not change.
299 - The `gnupload' script has been revamped.
301 - The `depcomp' and `compile' scripts now work with MSVC under MSYS.
303 - The targets `install' and `uninstall' are more efficient now, in that
304 for example multiple files from one Automake variable such as
305 `bin_SCRIPTS' are copied in one `install' (or `libtool --mode=install')
306 invocation if they do not have to be renamed.
308 Both install and uninstall may sometimes enter (`cd' into) the target
309 installation directory now, when no build-local scripts are used.
311 Both install and uninstall do not fail anymore but do nothing if an
312 installation directory variable like `bindir' is set to the empty string.
314 For built-in rules, `make install' now fails reliably if installation
315 of a file failed. Conversely, `make uninstall' even succeeds when
316 issued multiple times.
318 These changes may need some adjustments from users: For example,
319 some `install' programs refuse to install multiple copies of the
320 same file in one invocation, so you may need to remove duplicate
321 entries from file lists.
323 Also, within one set of files, say, nobase_data_DATA, the order of
324 installation may be changed, or even unstable among different hosts,
325 due to the use of associative arrays in awk. The increased use of
326 awk matches a similar move in Autoconf to provide for better scaling.
328 Further, most undocumented per-rule install command variables such as
329 binSCRIPT_INSTALL have been removed because they are not needed any
330 more. Packages which use them should be using the appropriate one of
331 INSTALL_{DATA,PROGRAM,SCRIPT} or their install_sh_{DATA,PROGRAM,SCRIPT}
332 counterpart, depending on the type of files and the need for automatic
333 target directory creation.
335 - The "deleted header file problem" for *.m4 files is avoided by
336 stub rules. This allows `make' to trigger a rerun of `aclocal'
337 also if some previously needed macro file has been removed.
339 - Rebuild rules now also work for a removed `subdir/Makefile.in' in
340 an otherwise up to date tree.
342 - The `color-tests' option causes colored test result output on terminals.
344 - The `parallel-tests' option enables a new test driver that allows for
345 parallel test execution, inter-test dependencies, lazy test execution
346 for unit-testing, re-testing only failed tests, and formatted result output
347 as RST (reStructuredText) and HTML. Enabling this option may require some
348 changes to your test suite setup; see the manual for details.
350 - The `silent-rules' option enables Linux kernel-style silent build output.
351 This option requires the widely supported but non-POSIX `make' feature
352 of recursive variable expansion, so do not use it if your package needs
353 to build with `make' implementations that do not support it.
355 To enable less verbose build output, the developer has to use the Automake
356 option `silent-rules' in `AM_INIT_AUTOMAKE', or call the `AM_SILENT_RULES'
357 macro. The user may then set the default verbosity by passing the
358 `--enable-silent-rules' option to `configure'. At `make' run time, this
359 default may be overridden using `make V=0' for less verbose, and `make V=1'
360 for backward-compatible verbose output.
362 - New prefix `notrans_' for manpages which should not be transformed
363 by --program-transform.
365 - New macro AM_COND_IF for conditional evaluation and conditional
368 - For AC_CONFIG_LINKS, if source and destination are equal, do not
369 remove the file in a non-VPATH build. Such setups work with Autoconf
372 - AM_MAINTAINER_MODE now allows for an optional argument specifying
375 - AM_SUBST_NOTMAKE may prevent substitution of AC_SUBSTed variables,
376 useful especially for multi-line values.
378 - Automake's early configure-time sanity check now diagnoses an
379 unsafe absolute source directory name and makes configure fail.
381 - The Automake macros and rules cope better with whitespace in the
382 current directory name, as long as the relative path to `configure'
383 does not contain whitespace. To this end, the values of `$(MISSING)'
384 and `$(install_sh)' may contain suitable quoting, and their expansion
385 might need `eval'uation if used outside of a makefile. These
386 undocumented variables may be used in several documented macros such
387 as $(AUTOCONF) or $(MAKEINFO).
391 * Long standing bugs:
393 - Fix aix dependency tracking for libtool objects.
395 - Work around AIX sh quoting issue in AC_PROG_CC_C_O, leading to
396 unnecessary use of the `compile' script.
398 - For nobase_*_LTLIBRARIES with nonempty directory components, the
399 correct `-rpath' argument is used now.
401 - `config.status --file=Makefile depfiles' now also works with the
402 extra quoting used internally by Autoconf 2.62 and newer
403 (it used to work only without the `--file=' bit).
405 - The `missing' script works better with versioned tool names.
407 - Semantics for `missing help2man' have been revamped:
409 Previously, if `help2man' was not present, `missing help2man' would have
410 the following semantics: if some man page was out of date but present, then
411 a warning would be printed, but the exit status was 0. If the man page was
412 not present at all, then `missing' would create a replacement man page
413 containing an error message, and exit with a status of 2. This does not play
414 well with `make': the next run will see this particular man page as being up
415 to date, and will only error out on the next generated man page, if any;
416 repeat until all pages are done. This was not desirable.
418 These are the new semantics: if some man page is not present, and help2man
419 is not either, then `missing' will warn and generate the replacement page
420 containing the error message, but exit successfully. However, `make dist'
421 will ensure that no such bogus man pages are packaged into a tarball.
423 - Targets provided by automake behave better with `make -n', in that they
424 take care not to create files.
426 - `config.status Makefile... depfiles' works fine again in the presence of
427 disabled dependency tracking.
429 - The default no-op recursive rules for these targets also work with BSD make
430 now: html, install-html, install-dvi, install-pdf, install-pdf, install-info.
432 - `make distcheck' works also when both a directory and some file below it
433 have been added to a distribution variable, such as EXTRA_DIST or *_SOURCES.
435 - Texinfo dvi, ps, pdf, and html output files are not removed upon
436 `make mostlyclean' any more; only the LaTeX by-products are.
438 - Renamed objects also work with the `subdir-objects' option and
439 source file languages which Automake does not know itself.
441 - `automake' now correctly complains about variable assignments which are
442 preceded by a comment, extend over multiple lines with backslash-escaped
443 newlines, and end in a comment sign. Previous versions would silently
444 and wrongly ignore such assignments completely.
446 * Bugs introduced by 1.10:
448 - Fix output of dummy dependency files in presence of post-processed
449 Makefile.in's again, but also cope with long lines.
451 - $(EXEEXT) is automatically appended to filenames of XFAIL_TESTS
452 that have been declared as programs in the same Makefile.
453 This is for consistency with the analogous change to TESTS in 1.10.
455 - Fix order of standard includes to again be `-I. -I$(srcdir)',
456 followed by directories containing config headers.
460 * Version requirements:
462 - Autoconf 2.60 or greater is required.
464 - Perl 5.6 or greater is required.
466 * Changes to aclocal:
468 - aclocal now also supports -Wmumble and -Wno-mumble options.
470 - `dirlist' entries (for the aclocal search path) may use shell
471 wildcards such as `*', `?', or `[...]'.
473 - aclocal supports an --install option that will cause system-wide
474 third-party macros to be installed in the local directory
475 specified with the first -I flag. This option also uses #serial
476 lines in M4 files to upgrade local macros.
478 The new aclocal options --dry-run and --diff help to review changes
479 before they are installed.
481 - aclocal now outputs an autoconf version check in aclocal.m4 in
482 projects using automake.
484 For a few years, automake and aclocal have been calling autoconf
485 (or its underlying engine autom4te) to accurately retrieve the
486 data they need from configure.ac and its siblings. Doing so can
487 only work if all autotools use the same version of autoconf. For
488 instance a Makefile.in generated by automake for one version of
489 autoconf may stop working if configure is regenerated with another
490 version of autoconf, and vice versa.
492 This new version check ensures that the whole build system has
493 been generated using the same autoconf version.
495 * Support for new Autoconf macros:
497 - The new AC_REQUIRE_AUX_FILE Autoconf macro is supported.
499 - If `subdir-objects' is set, and AC_CONFIG_LIBOBJ_DIR is specified,
500 $(LIBOBJS), $(LTLIBOBJS), $(ALLOCA), and $(LTALLOCA) can be used
501 in different directories. However, only one instance of such a
502 library objects directory is supported.
504 * Change to Libtool support:
506 - Libtool generic flags (those that go before the --mode=MODE option)
507 can be specified using AM_LIBTOOLFLAGS and target_LIBTOOLFLAGS.
509 * Yacc and Lex changes:
511 - The rebuild rules for distributed Yacc and Lex output will avoid
512 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
515 - ylwrap is now always used for lex and yacc source files,
516 regardless of whether there is more than one source per directory.
520 - Preprocessed assembler (*.S) compilation now honors CPPFLAGS,
521 AM_CPPFLAGS and per-target _CPPFLAGS, and supports dependency
522 tracking, unlike non-preprocessed assembler (*.s).
524 - subdir-object mode works now with Assembler. Automake assumes
525 that the compiler understands `-c -o'.
527 - Preprocessed assembler (*.S) compilation now also honors
528 $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES).
530 - Improved support for Objective C:
531 - Autoconf's new AC_PROG_OBJC will enable automatic dependency tracking.
532 - A new section of the manual documents the support.
534 - New support for Unified Parallel C:
535 - AM_PROG_UPC looks for a UPC compiler.
536 - A new section of the manual documents the support.
538 - Per-target flags are now correctly handled in link rules.
540 For instance maude_CFLAGS correctly overrides AM_CFLAGS; likewise
541 for maude_LDFLAGS and AM_LDFLAGS. Previous versions bogusly
542 preferred AM_CFLAGS over maude_CFLAGS while linking, and they
543 used both AM_LDFLAGS and maude_LDFLAGS on the same link command.
545 The fix for compiler flags (i.e., using maude_CFLAGS instead of
546 AM_CFLAGS) should not hurt any package since that is how _CFLAGS
547 is expected to work (and actually works during compilation).
549 However using maude_LDFLAGS "instead of" AM_LDFLAGS rather than
550 "in addition to" breaks backward compatibility with older versions.
551 If your package used both variables, as in
553 AM_LDFLAGS = common flags
555 a_LDFLAGS = more flags
558 and assumed *_LDFLAGS would sum up, you should rewrite it as
560 AM_LDFLAGS = common flags
562 a_LDFLAGS = $(AM_LDFLAGS) more flags
565 This new behavior of *_LDFLAGS is more coherent with other
566 per-target variables, and the way *_LDFLAGS variables were
567 considered internally.
569 * New installation targets:
571 - New targets mandated by GNU Coding Standards:
576 By default they will only install Texinfo manuals.
577 You can customize them with *-local variants:
583 - The undocumented recursive target `uninstall-info' no longer exists.
584 (`uninstall' is in charge of removing all possible documentation
585 flavors, including optional formats such as dvi, ps, or info even
586 when `no-installinfo' is used.)
588 * Miscellaneous changes:
590 - Automake no longer complains if input files for AC_CONFIG_FILES
591 are specified using shell variables.
593 - clean, distribution, or rebuild rules are normally disabled for
594 inputs and outputs of AC_CONFIG_FILES, AC_CONFIG_HEADERS, and
595 AC_CONFIG_LINK specified using shell variables. However, if these
596 variables are used as ${VAR}, and AC_SUBSTed, then Automake will
597 be able to output rules anyway.
598 (See the Automake documentation for AC_CONFIG_FILES.)
600 - $(EXEEXT) is automatically appended to filenames of TESTS
601 that have been declared as programs in the same Makefile.
602 This is mostly useful when some check_PROGRAMS are listed in TESTS.
604 - `-Wportability' has finally been turned on by default for `gnu' and
605 `gnits' strictness. This means, automake will complain about %-rules
606 or $(GNU Make functions) unless you switch to `foreign' strictness or
607 use `-Wno-portability'.
609 - Automake now uses AC_PROG_MKDIR_P (new in Autoconf 2.60), and uses
610 $(MKDIR_P) instead of $(mkdir_p) to create directories. The
611 $(mkdir_p) variable is still defined (to the same value as
612 $(MKDIR_P)) but should be considered obsolete. If you are using
613 $(mkdir_p) in some of your rules, please plan to update them to
614 $(MKDIR_P) at some point.
616 - AM_C_PROTOTYPES and ansi2knr are now documented as being obsolete.
617 They still work in this release, but may be withdrawn in a future one.
619 - Inline compilation rules for gcc3-style dependency tracking are
622 - Automake installs a "Hello World!" example package in $(docdir).
623 This example is used throughout the new "Autotools Introduction"
624 chapter of the manual.
628 * Makefile.in bloat reduction:
630 - Inference rules are used to compile sources in subdirectories when
631 the `subdir-objects' option is used and no per-target flags are
632 used. This should reduce the size of some projects a lot, because
633 Automake used to output an explicit rule for each such object in
636 - Automake no longer outputs three rules (.o, .obj, .lo) for each
637 object that must be built with explicit rules. It just outputs
638 the rules required to build the kind of object considered: either
639 the two .o and .obj rules for usual objects, or the .lo rule for
642 * Change to Libtool support:
644 - Libtool tags are used with libtool versions that support them.
645 (I.e., with Libtool 1.5 or greater.)
647 - Automake is now able to handle setups where a libtool library is
648 conditionally installed in different directories, as in
651 lib_LTLIBRARIES = liba.la
653 pkglib_LTLIBRARIES = liba.la
655 liba_la_SOURCES = ...
657 * Changes to aclocal:
659 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
660 really evaluated, before it decides to include them in aclocal.m4.
661 This solves nasty problems with conditional redefinitions of
662 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
663 *.m4 files to be included in any project using these macros.
664 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
665 most famous instance of this bug.)
667 - Do not complain about missing conditionally AC_REQUIREd macros
668 that are not actually used. In 1.8.x aclocal would correctly
669 determine which of these macros were really needed (and include
670 only these in the package); unfortunately it would also require
671 all of them to be present in order to run. This created
672 situations were aclocal would not work on a tarball distributing
673 all the macros it uses. For instance running aclocal on a project
674 containing only the subset of the Gettext macros in use by the
675 project did not work, because gettext conditionally requires other
678 * Portability improvements:
680 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
681 tar-pax. The new option filename-length-max=99 helps diagnosing
682 filenames that are too long for tar-v7. (PR/414)
684 - Variables aumented with `+=' are now automatically flattened (i.e.,
685 trailing backslashes removed) and then wrapped around 80 colummns
686 (adding trailing backslashes). In previous versions, a long series
692 would result in a single-line definition of VAR that could possibly
693 exceed the maximum line length of some make implementations.
695 Non-augmented variables are still output as they are defined in
700 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
701 Works the same as the old Fortran 77 implementation; just replace
702 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
703 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
705 - Support for conditional _LISP.
707 - Support for conditional -hook and -local rules (PR/428).
709 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
711 - Automake will not write any Makefile.ins after the first error it
712 encounters. The previous Makefile.ins (if any) will be left in
713 place. (Warnings will not prevent output, but remember they can
714 be turned into errors with -Werror.)
716 - The restriction that SUBDIRS must contain direct children is gone.
719 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
720 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
724 * Long standing bugs:
726 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
727 so that `make distclean' and `make maintainer-clean' can work.
729 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
731 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
733 - Polish diagnostic when no input file is found.
737 * Long standing bugs:
739 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
740 overridden by the user.
742 - Honor PATH_SEPARATOR in various places of the Automake package, for
745 - Adjust dependency tracking mode detection to ICC 8.0's new output.
748 - Fix install-sh so it can install the `mv' binary... using `mv'.
750 - Fix tru64 dependency tracking for libtool objects.
752 - Work around Exuberant Ctags when creating a TAGS files in a directory
753 without files to scan but with subdirectories to include.
755 * Bugs introduced by 1.8:
757 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
758 not defined in the same conditions as the _LDADD that uses it.
760 - Do not warn when JAVAROOT is overridden, this is legitimate.
764 * Long standing bugs:
766 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
767 or any of the other *dir variables contain a space.
769 Please note that Automake does not and cannot support spaces in
770 filenames that are involved during the build. This change affects
771 only installation paths, so that `make install' does not bomb out
772 in packages configured with
773 ./configure --prefix '/c/Program Files'
775 - Fix the depfiles output so it works with GNU sed (<4.1) even when
776 POSIXLY_CORRECT is set.
778 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
779 since Autoconf 2.54, which defines LIBOBJS itself.
781 - Fix a potential (but unlikely) race condition in parallel elisp
782 builds. (Introduced in 1.7.3.)
784 - Do not assume that users override _DEPENDENCIES in all conditions
785 where Automake will try to define them.
787 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
788 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
791 This fix also affects the $(mkdir_p) variable defined since
792 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
793 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
795 - Secure temporary directory creation in `make distcheck'. (PR/413)
797 - Do not generate two build rules for `parser.h' when the
798 parser appears in two different conditionals.
800 - Work around a Solaris 8 /bin/sh bug in the test for dependency
801 checking. Usually ./configure will not pick this shell; so this
802 fix only helps cases where the shell is forced to /bin/sh.
804 * Bugs introduced by 1.8:
806 - In some situations (hand-written `m4_include's), aclocal would
807 call the `File::Spec->rel2abs' method, which was only introduced
808 in Perl 5.6. This new version reestablish support Perl 5.005.
810 It is likely that the next major Automake releases will require at
811 least Perl 5.6. Consider upgrading your development environment
812 if you are still using the five-year-old Perl 5.005.
814 - Automake would sometimes fail to define rules for targets listed
815 in variables defined in multiple conditions. For instance on
821 it would define only the `a.$(OBJEXT): a.c' rule and omit the
822 `b.$(OBJEXT): b.c' rule.
824 * New sections in manual:
826 - Third-Party Makefiles: how to interface third party Makefiles.
827 - Upgrading: upgrading packages to newer Automake versions.
828 - Multiple Outputs: handling tools that produce many outputs.
832 * A (well known) portability bug slipped in the changes made to
833 install-sh in Automake 1.8.1. The broken install-sh would refuse to
834 install anything on Tru64.
836 * Fix install rules for conditionally built python files. (This never
841 * Bugs introduced by 1.8:
843 - Fix Config.pm import error with old Perl versions (at least
844 5.005_03). One symptom is that aclocal could not find its macro
847 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
848 created by `make install' are always world readable, even if the
849 installer happens to have an overly restrictive umask (e.g. 077).
850 This was a mistake and has been reverted. There are at least two
851 reasons why we must not use `-m 0755':
852 - it causes special bits like SGID to be ignored,
853 - it may be too restrictive (some setups expect 775 directories).
855 - Fix aclocal to honor definitions located in files which have been
856 m4_included manually. aclocal 1.8 had been updated to check
857 m4_included files for new requirements, but forgot that these
858 m4_included files can also provide new definitions.
860 Note that if you have such a setup, we recommend you get rid of
861 it. In the past, there was a reason to m4_include files manually:
862 aclocal used to duplicate entire M4 files into aclocal.m4, even
863 files that were distributed. Some packages were therefore
864 m4_including the distributed file directly, and playing some
865 tricks to ensure aclocal would not copy that file to aclocal.m4,
866 in order to limit the amount of duplication. Since aclocal 1.8.x
867 will precisely output m4_includes for local M4 files, we recommend
868 that you clean up your setup, removing all manual m4_includes and
869 letting aclocal output them.
871 - Output detailed menus in the Info version if the Automake manual,
872 so that Emacs can locate the indexes.
874 - configure.ac and configure were listed twice in DIST_COMMON (an
875 internal variable where Automake lists configury files to
876 distribute). This was harmless, but unaesthetic.
878 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
879 This was an issue only in the Automake package itself, not in
882 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
883 DEST:SRC. This was wrong, as some packages do
884 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
887 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
888 argument. This caused two kinds of failures:
889 - Rules installing data in a conditionally defined directory
890 failed when that directory was undefined. In this case no
891 argument was supplied.
892 - `make installdirs' failed, because several directories were
893 passed to $(mkdir_p). This was an issue only on platform
894 were $(mkdir_p) is implemented with `install-sh -d'.
895 $(mkdir_p) as been changed to accept 0 or more arguments, as
898 * Long-standing bugs:
900 - Fix an unexpected diagnostic occurring when users attempt
901 to override some internal variables that Automake appends to.
903 - aclocal now scans configure.ac for macro definitions (PR/319).
905 - Fix a portability issue with OSF1/Tru64 Make. If a directory
906 distributes files which are outside itself (this usually occurs
907 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
908 from a parent package), then `make distcheck' fails due to an
909 optimization performed by OSF1/Tru64 Make in its VPATH handling.
910 (tests/subpkg2.test failure)
912 - Fix another portability issue with Sun and OSF1/Tru64 Make.
913 In a VPATH-build configuration, `make install' would install
914 nobase_ files to wrong locations.
916 - Fix a Perl `uninitialized value' diagnostic occurring when
917 automake complains that a Texinfo file does not have a
918 @setfilename statement.
920 - Erase config.status.lineno during `make distclean'. This file
921 can be created by config.status. Automake already knew about
922 configure.lineno, but forgot config.status.lineno.
924 - Distribute all files, even those which are built and installed
925 conditionally. This change affects files listed in conditionally
926 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
927 as well as those listed in conditionally defined dist_*_DATA,
928 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
930 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
931 doesn't conform to POSIX.
933 - Normalize help strings for configure variables and options added
938 - Check for python2.4 in AM_PATH_PYTHON.
940 * Spurious failures in test suite:
942 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
943 tests/ltconv.test: fix failures with CVS Libtool.
944 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
945 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
946 fix failures with old Texinfo versions.
952 - The NEWS file is more verbose.
956 - Autoconf 2.58 or greater is required.
960 - Default source file names in the absence of a _SOURCES declaration
961 are made by removing any target extension before appending `.c', so
962 to make the libtool module `foo.la' from `foo.c', you only need to
965 lib_LTLIBRARIES = foo.la
966 foo_la_LDFLAGS = -module
968 For backward compatibility, foo_la.c will be used instead of
969 foo.c if this file exists or is the explicit target of a rule.
970 However -Wobsolete will warn about this deprecated naming.
972 - AR's `cru' flags are now set in a global ARFLAGS variable instead
973 of being hard-coded in each $(AR) invocation, so they can be
974 substituted from configure.ac. This has been requested by people
975 dealing with non-POSIX ar implementations.
977 - New warning option: -Woverride. This will warn about any user
978 target or variable definitions which override Automake
981 - Texinfo rules back up and restore info files when makeinfo fails.
983 - Texinfo rules now support the `html' target.
984 Running this requires Texinfo 4.0 or greater.
986 `html' is a new recursive target, so if your package mixes
987 hand-crafted `Makefile.in's with Automake-generated
988 `Makefile.in's, you should adjust the former to support (or
989 ignore) this target so that `make html' recurses successfully. If
990 you had a custom `html' rule in your `Makefile.am', it's better to
991 rename it as `html-local', otherwise your rule will override
992 Automake's new rule (you can check that by running `automake
993 -Woverride') and that will stop the recursion to subdirectories.
995 Last but not least, this `html' rule is declared PHONY, even when
996 overridden. Fortunately, it appears that few packages use a
997 non-PHONY `html' rule.
999 - Any file which is m4_included from configure.ac will appear as a
1000 configure and Makefile.in dependency, and will be automatically
1003 - The rules for rebuilding Makefiles and Makefile.ins will now
1004 rebuild all Makefiles and all Makefile.ins at once when one of
1005 configure's dependencies has changed. This is considerably faster
1006 than previous implementations, where config.status and automake
1007 were run separately in each directory (this still happens when you
1008 change a Makefile.am locally, without touching configure.ac or
1009 friends). Doing this also solves a longstanding issue: these
1010 rebuild rules failed to work when adding new directories to the
1011 tree, forcing you to run automake manually.
1013 - For similar reasons, the rules to rebuild configure,
1014 config.status, and aclocal.m4 are now defined in all directories.
1015 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
1016 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
1017 should better define them in all directories. This is easily done
1018 using an AC_SUBST (make sure you prefix these dependencies with
1019 $(top_srcdir) since this variable will appear at different
1020 levels of the build tree).
1022 - aclocal will now use `m4_include' instead of copying local m4
1023 files into aclocal.m4. (Local m4 files are those you ship with
1024 your project, other files will be copied as usual.)
1026 Because m4_included files are automatically distributed, it means
1027 for most projects there is no point in EXTRA_DISTing the list of
1028 m4 files which are used. (You can probably get rid of
1029 m4/Makefile.am if you had one.)
1031 - aclocal will avoid touching aclocal.m4 when possible, so that
1032 Autom4te's cache isn't needlessly invalidated. This behavior can
1033 be switched off with the new `--force' option.
1035 - aclocal now uses Autoconf's --trace to detect macros which are
1036 actually used and will no longer include unused macros simply
1037 because they where mentioned. This was often the case for macros
1038 called conditionally.
1040 - New options no-dist and no-dist-gzip.
1042 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
1043 py-compile, and ylwrap, now all understand --version and --help.
1045 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
1046 links as part of the distclean target and including source files in
1049 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
1050 argument. The latter can be used to override the default behavior
1051 (which is to abort).
1053 - Automake will exit with $? = 63 on version mismatch. (So does
1054 Autoconf 2.58) missing knows this, and in this case it will
1055 emulate the tools as if they were absent. Because older versions
1056 of Automake and Autoconf did not use this exit code, this change
1057 will only be useful in projects generated with future versions of
1060 - When using AC_CONFIG_FILES with multiple input files, Automake
1061 generates the first ".in" input file for which a ".am" exists.
1062 (Former versions would try to use only the first input file.)
1064 - lisp_DATA is now allowed. If you are using the empty ELCFILES
1065 idiom to disable byte-compilation of lisp_LISP files, it is
1066 recommended that you switch to using lisp_DATA. Note that
1067 this is not strictly equivalent: lisp_DATA will install elisp
1068 files even if emacs is not installed, while *_LISP do not
1069 install anything unless emacs is found.
1071 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
1072 available. This selection is achieved through the Makefile
1073 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
1074 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
1075 `$(install_sh) -m 0755 -d'.
1079 - Because `mkdir -p' is available on most platforms, and we can use
1080 `install-sh -d' when it is not, the use of the mkinstalldirs
1081 script is being phased out. `automake --add-missing' no longer
1082 installs it, and if you remove mkinstalldirs from your package,
1083 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
1085 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
1086 gettextize and autopoint will install it when needed. Automake
1087 will continue to define the $(mkinstalldirs) and to distribute
1088 mkinstalldirs when this script is in the source tree.
1090 - AM_PROG_CC_STDC is now empty. The content of this macro was
1091 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
1092 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
1093 renaming should be safe, even if you have to support several,
1094 versions of Automake, because AC_PROG_CC defines this variable
1095 since Autoconf 2.54.)
1097 - Some users where using the undocumented ACLOCAL_M4_SOURCES
1098 variable to override the aclocal.m4 dependencies computed
1099 (inaccurately) by older versions of Automake. Because Automake
1100 now tracks configure's m4 dependencies accurately (see m4_include
1101 above), the use of ACLOCAL_M4_SOURCES should be considered
1102 obsolete and will be flagged as such when running `automake
1107 - Defining programs conditionally using Automake conditionals no
1108 longer leads to a combinatorial explosion. The following
1109 construct used to be troublesome when used with dozens of
1124 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
1126 - Due to implementation constraints, previous versions of Automake
1127 proscribed multiple conditional definitions of some variables
1137 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
1138 This restriction has been lifted, and these variables now
1139 support multiple conditional definitions as do other variables.
1141 - Cleanup the definitions of $(distdir) and $(top_distdir).
1142 $(top_distdir) now points to the root of the distribution
1143 directory created during `make dist', as it did in Automake 1.4,
1144 not to the root of the build tree as it did in intervening
1145 versions. Furthermore these two variables are now only defined in
1146 the top level Makefile, and passed to sub-directories when running
1149 - The --no-force option now correctly checks the Makefile.in's
1150 dependencies before deciding not to update it.
1152 - Do not assume that make files are called Makefile in cleaning rules.
1154 - Update .info files in the source tree, not in the build tree. This
1155 is what the GNU Coding Standard recommend. Only Automake 1.7.x
1156 used to update these files in the build tree (previous versions did
1157 it in the source tree too), and it caused several problems, varying
1158 from mere annoyance to portability issues.
1160 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
1161 when --add-missing and --force-missing are used. For backward
1162 compatibility --add-missing will continue to install COPYING (in
1163 `gnu' strictness) when none of these three files exist, but this
1164 use is deprecated: you should better choose a license yourself and
1165 install it once for all in your source tree (and in your code
1168 - Fix ylwrap so that it does not overwrite header files that haven't
1169 changed, as the inline rule already does.
1171 - User-defined rules override automake-defined rules for the same
1172 targets, even when rules do not have commands. This is not new
1173 (and was documented), however some of the automake-generated
1174 rules have escaped this principle in former Automake versions.
1175 Rules for the following targets are affected by this fix:
1177 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
1178 info, info-am, install-data-am, install-exec-am, install-info,
1179 install-info-am, install-man, installcheck-am, maintainer-clean,
1180 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
1181 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
1183 Practically it means that an attempt to supplement the dependencies
1184 of some target, as in
1186 clean: my-clean-rule
1188 will now *silently override* the automake definition of the
1189 rule for this target. Running `automake -Woverride' will diagnose
1190 all such overriding definitions.
1192 It should be noted that almost all these targets support a *-local
1193 variant that is meant to supplement the automake-defined rule
1194 (See node `Extending' in the manual). The above rule should
1197 clean-local: my-clean-rule
1199 These *-local targets have been documented since at least
1200 Automake 1.2, so you should not fear the change if you have
1201 to support multiple automake versions.
1205 - The Automake manual is now distributed under the terms of the GNU FDL.
1207 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
1209 - core dumps are no longer removed by the cleaning rules. There are
1210 at least three reasons for this:
1211 1. These files should not be created by any build step,
1212 so their removal do not fit any of the cleaning rules.
1213 Actually, they may be precious to the developer.
1214 2. If such file is created during a build, then it's clearly a
1215 bug Automake should not hide. Not removing the file will
1216 cause `make distcheck' to complain about its presence.
1217 3. Operating systems have different naming conventions for
1218 core dump files. A core file on one system might be a
1219 completely legitimate data file on another system.
1221 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
1222 defined by Automake. This means that any definition in the
1223 environment will be used, unless overridden in the Makefile.am or
1224 on the command line. The old behavior, where these variables were
1225 defined empty in each Makefile, can be obtained by AC_SUBSTing or
1226 AC_ARG_VARing each variable from configure.ac.
1228 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
1229 documented. (The is not a new feature, these variables have
1230 been there since at least Automake 1.4.)
1232 Bugs fixed in 1.7.9:
1233 * Fix install-strip to work with nobase_ binaries.
1234 * Fix renaming of #line directives in ylwrap.
1235 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
1237 Bugs fixed in 1.7.8:
1238 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
1239 * Fix detection of Debian's install-info, broken since version 1.5.
1240 (Debian bug #213524).
1241 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
1242 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
1244 Bugs fixed in 1.7.7:
1245 * The implementation of automake's --no-force option is unreliable,
1246 so this option is ignored in this version. A real fix will appear in
1247 Automake 1.8. (Debian Bug #206299)
1248 * AM_PATH_PYTHON: really check the whole list of interpreters if no
1249 argument is given. (PR/399)
1250 * Do not warn about leading `_' in variable names, even with -Wportability.
1251 * Support user redefinitions of TEXINFO_TEX.
1252 * depcomp: support AIX Compiler version 6.
1253 * Fix missing rebuilds during `make dist' with BSD make.
1254 (Could produce tarballs containing out-of-date files.)
1255 * Resurrect multilib support.
1256 * Noteworthy manual updates:
1257 - Extending aclocal: how to write m4 macros that won't trigger warnings
1259 - A Shared Library: Rewrite and split into subsections.
1261 Bugs fixed in 1.7.6:
1262 * Fix depcomp's icc mode for ICC 7.1.
1263 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
1264 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
1265 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
1266 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
1267 * Remove Latin-1 characters from elisp-comp.
1268 * Update the manual's @dircategory to match the Free Software Directory.
1270 Bugs fixed in 1.7.5:

1272 (Debian bug #191717)
1273 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
1274 that caused invalid Makefile.ins to be generated.
1275 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
1276 * New FAQ entry: renamed objects.
1278 Bugs fixed in 1.7.4:
1279 * Tweak the TAGS rule to support Exuberant Ctags (in addition to
1280 the Emacs implementation)
1281 * Fix output of aclocal.m4 dependencies in subdirectories.
1282 * Use `mv -f' instead of `mv' in fastdep rules.
1283 * Upgrade mdate-sh to work on OS/2.

1292 * Minor documentation fixes.
1294 Bugs fixed in 1.7.3:
1295 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
1296 * Query distutils for `pythondir' and `pythonexecdir', instead of
1297 using an hardcoded path. This should allow builds on 64-bit
1298 distributions that usually use lib64/ instead of lib/.
1299 * AM_PATH_PYTHON will also search for python2.3.
1300 * elisp files are now built all at once instead of one by one. Besides
1301 incurring a speed-up, this is required to support interdependent elisp files.
1302 * Support for DJGPP:
1303 - `make distcheck' will now work in `_inst/' and `_build' instead
1304 of `=inst/' and `=build/'
1305 - use `_dirstamp' when the file-system doesn't support `.dirstamp'
1306 - install/uninstall `*.i[0-9][0-9]'-style info files
1307 - more changes that affect only the Automake package (not its output)
1308 * Fix some incompatibilities with upcoming perl-5.10.
1309 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
1310 PACKAGE and VERSION.
1312 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
1313 is troublesome with gcc and Solaris compilers. (PR/385)
1314 - makedepend mode: work with Libtool. (PR/385 too)
1316 * better support for unusual gettext setups, such as multiple po/ directories
1318 - Flag missing po/ and intl/ directories as warnings, not errors.

1327 * Fix installation and uninstallation of Info files built in subdirectories.
1328 * Do not run `./configure --with-included-gettext' during `make distcheck'
1329 if AM_GNU_GETTEXT([external]) is used.
1330 * Correctly uninstall renamed man pages.
1331 * Do not strip escaped newline in variables defined in one condition
1332 and augmented in another condition.
1333 * Fix ansi2knr rules for LIBOBJS sources.
1334 * Clean all known Texinfo index files, not only those which appear to
1335 be used, because we cannot know wich indexes are used in included files.
1336 (PR/375, Debian Bug #168671)
1337 * Honor only the first @setfilename seen in a Texinfo file.
1338 * Treat "required file X not found" diagnostics as errors (exit status 1).
1339 * Don't complain that a required file is not found when it is a Makefile
1341 * Don't use single suffix inference rules when building `.info'-less
1342 Info files, for the sake of Solaris make.
1343 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
1344 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
1345 * Warn about multiple inference rules when -Wportability is used. (PR/372)
1346 * Fix building of deansified files from subdirectories. (PR/370)
1347 * Add missing `fi' in the .c->.obj rules.
1348 * Improve install-sh to work even when names contain spaces or certain
1349 (but not all) shell metachars.
1350 * Fix the following spurious failures in the test suite:
1351 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
1352 * Noteworthy manual updates:
1353 - Augment the section about BUILT_SOURCES.
1354 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
1356 Bugs fixed in 1.7.1:
1357 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
1359 * Aclocal should now recognize macro names containing parentheses, e.g.
1360 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
1361 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
1363 * Install Python files even if they were built. (PR/369)
1364 * Have stamp-vti dependent upon configure instead of configure.ac, as the
1365 version might not be defined in the latter. (PR/358)
1366 * Reorder arguments passed to a couple of commands, so things works
1367 when POSIXLY_CORRECT=1.
1368 * Fix a regex that can cause Perl to segfault on large input.
1370 * Fix distribution of packages that have some sources defined conditionally,
1371 as in the `Conditional compilation using Automake conditionals' example
1373 * Fix spurious test suite failures on IRIX.
1374 * Don't report a required variable as undefined if it has been
1375 defined conditionally for the "right" conditions.
1376 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
1377 `make distcheck' fails.
1378 * Fix distribution of included Makefile fragment, so we don't create
1379 spurious directories in the distribution. (PR/366)
1380 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
1383 * Autoconf 2.54 is required.
1384 * `aclocal' and `automake' will no longer warn about obsolete
1385 configure macros. This is done by `autoconf -Wobsolete'.
1386 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
1387 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
1388 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
1389 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
1390 `configure.ac' for you.
1391 * Support for per-program and per-library `_CPPFLAGS'.
1392 * New `ctags' target (builds CTAGS files).
1393 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
1394 (see `automake --help' or the manual for a list of them).
1395 * Honor the WARNINGS environment variable.
1396 * Omit the call to depcomp when using gcc3: call the compiler directly.
1397 * A new option, std-options, tests that programs support --help and --version
1398 when `make installcheck' is run. This is enabled by --gnits.
1399 * Texinfo rules now support the `ps' and `pdf' targets.
1400 * Info files are now created in the build directory, not the source directory.
1401 * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1
1403 * `make distcheck' will enforce DESTDIR support by attempting
1405 * `+=' can be used in conditionals, even if the augmented variable
1406 was defined for another condition.
1407 * Makefile fragments (inserted with `include') are always distributed.
1408 * Use Autoconf's --trace interface to inspect configure.ac and get
1409 a more accurate view of it.
1410 * Add support for extending aclocal's default macro search path
1411 using a `dirlist' file within the aclocal directory.
1412 * automake --output-dir is deprecated.
1413 * The part of the distcheck target that checks whether uninstall actually
1414 removes all installed files has been moved in a separate target,
1415 distuninstallcheck, so it can be overridden easily.
1419 * Support for AM_INIT_GETTEXT([external])
1420 * Bug fixes, including:
1421 - Fix Automake's own `make install' so it works even if `ln' doesn't.
1422 - nobase_ programs and scripts honor --program-transform correctly.
1423 - Erase configure.lineno during `make distclean'.

1439 - Don't choke on AM_LDFLAGS definitions.
1440 - Clean libtool objects from subdirectories.
1441 - Allow configure variables with reserved suffix and unknown prefix
1442 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
1443 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
1446 * Autoconf 2.52 is required.
1447 * automake no longer run libtoolize.
1448 This is the job of autoreconf (from GNU Autoconf).
1449 * `dist' generates all the archive flavors, as did `dist-all'.
1450 * `dist-gzip' generates the Gzip tar file only.
1451 * Combining Automake Makefile conditionals no longer lead to a combinatorial
1452 explosion. Makefile.in's keep a reasonable size.
1453 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
1454 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
1456 * `#line' of Lex and Yacc files are properly set.
1457 * EXTRA_DIST can contain generated directories.
1458 * Support for dot-less extensions in suffix rules.
1459 * The part of the distcheck target that checks whether distclean actually
1460 cleans all built files has been moved in a separate target, distcleancheck,
1461 so it can be overridden easily.
1462 * `make distcheck' will pass additional options defined in
1463 $(DISTCHECK_CONFIGURE_FLAGS) to configure.
1464 * Fixed CDPATH portability problems, in particular for MacOS X.
1465 * Fixed handling of nobase_ targets.

1469 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
1470 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
1471 (Note that "pkgname" is not "tarname", see the manual for details.)
1472 It is also possible to pass a list of global Automake options as
1473 first argument to this new form of AM_INIT_AUTOMAKE.
1474 * Compiler-based assembler is now called `CCAS'; people expected `AS'
1475 to be a real assembler.
1476 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
1477 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
