New in 1.7a: * The NEWS file is more verbose. * Autoconf 2.55 or greater is required. * Defining programs conditionally using Automake conditionals no longer leads to a combinatorial explosion. The following construct used to be troublesome when used with dozens of conditions. bin_PROGRAMS = a if COND1 bin_PROGRAMS += a1 endif if COND2 bin_PROGRAMS += a2 endif if COND3 bin_PROGRAMS += a3 endif ... Likewise for _LDADD and _LIBADD variables. * Automake now supports bin_PROGRAMS (or any *_PROGRAMS variable) being defined in several conditions. As in if COND1 bin_PROGRAMS = a1 endif if COND2 bin_PROGRAMS = a2 endif Likewise for _LDADD and _LIBADD variables. * install-sh now understands --version and --help. * Cleanup the definitions of $(distdir) and $(top_distdir). $(top_distdir) now points to the root of the distribution directory created during `make dist', as it did in Automake 1.4, not to the root of the build tree as it did in intervening versions. Furthermore these two variables are now only defined in the top level Makefile, and passed to sub-directories when running `make dist'. * elisp sources are compiled all at once, instead of one by one. This allows interdependencies and speeds up compilation. * lisp_DATA is now allowed. If you are using the empty ELCFILES idiom to disable byte-compilation of lisp_LISP files, it is recommanded that you switch to using lisp_DATA. ELCFILES is no longer documented. * AM_PROG_CC_STDC is now empty. The content of this macro was merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you should adjust it to use $ac_cv_prog_cc_stdc instead. (This renaming should be safe, even if you have to support several, versions of Automake, because AC_PROG_CC defines this variable since Autoconf 2.54.) * Texinfo rules back up and restore info files when makeinfo fails. New in 1.7: * Autoconf 2.54 is required. * `aclocal' and `automake' will no longer warn about obsolete configure macros. This is done by `autoconf -Wobsolete'. * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS, and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade `configure.ac' for you. * Support for per-program and per-library `_CPPFLAGS'. * New `ctags' target (builds CTAGS files). * Support for -Wmumble and -Wno-mumble, where mumble is a warning category (see `automake --help' or the manual for a list of them). * Honor the WARNINGS environment variable. * Omit the call to depcomp when using gcc3: call the compiler directly. * A new option, std-options, tests that programs support --help and --version when `make installcheck' is run. This is enabled by --gnits. * Texinfo rules now support the `ps' and `pdf' targets. * Info files are now created in the build directory, not the source directory. * info_TEXINFOS supports files in subdirectories (this requires Texinfo 4.1 or greater). * `make distcheck' will enforce DESTDIR support by attempting a DESTDIR install. * `+=' can be used in conditionals, even if the augmented variable was defined for another condition. * Makefile fragments (inserted with `include') are always distributed. * Use Autoconf's --trace interface to inspect configure.ac and get a more accurate view of it. * Add support for extending aclocal's default macro search path using a `dirlist' file within the aclocal directory. * automake --output-dir is deprecated. * The part of the distcheck target that checks whether uninstall actually removes all installed files has been moved in a separate target, distuninstallcheck, so it can be overridden easily. * Many bug fixes. New in 1.6: * Autoconf 2.52 is required. * automake no longer run libtoolize. This is the job of autoreconf (from GNU Autoconf). * `dist' generates all the archive flavors, as did `dist-all'. * `dist-gzip' generates the Gzip tar file only. * Combining Automake Makefile conditionals no longer lead to a combinatorial explosion. Makefile.in's keep a reasonable size. * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T are no longer shipped, since Autoconf 2.52 provides them (both as AM_ and AC_). * `#line' of Lex and Yacc files are properly set. * EXTRA_DIST can contain generated directories. * Support for dot-less extensions in suffix rules. * The part of the distcheck target that checks whether distclean actually cleans all built files has been moved in a separate target, distcleancheck, so it can be overridden easily. * `make distcheck' will pass additional options defined in $(DISTCHECK_CONFIGURE_FLAGS) to configure. * Fixed CDPATH portability problems, in particular for MacOS X. * Fixed handling of nobase_ targets. * Fixed support of implicit rules leading to .lo objects. * Fixed late inclusion of --add-missing files (e.g. depcomp) in DIST_COMMON * Added uninstall-hook target * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct. You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead. (Note that "pkgname" is not "tarname", see the manual for details.) It is also possible to pass a list of global Automake options as first argument to this new form of AM_INIT_AUTOMAKE. * Compiler-based assembler is now called `CCAS'; people expected `AS' to be a real assembler. * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required. * aclocal and automake are also installed with the version number appended, and some of the install directory names have changed. This lets you have multiple versions installed simultaneously. * Support for parsers and lexers in subdirectories. New in 1.5: * Support for `configure.ac'. * Support for `else COND', `endif COND' and negated conditions `!COND'. * `make dist-all' is much faster. * Allows '@' AC_SUBSTs in macro names. * Faster AM_INIT_AUTOMAKE (requires update of `missing' script) * User-side dependency tracking. Developers no longer need GNU make * Python support * Uses DIST_SUBDIRS in some situations when SUBDIRS is conditional * Most files are correctly handled if they appear in subdirs For instance, a _DATA file can appear in a subdir * GNU tar is no longer required for `make dist' * Added support for `dist_' and `nodist_' prefixes * Added support for `nobase_' prefix * Compiled Java support * Support for per-executable and per-library compilation flags * Many bug fixes New in 1.4: * Added support for the Fortran 77 programming language. * Re-indexed the Automake Texinfo manual. * Added `AM_FOOFLAGS' variable for each compiler invocation; e.g. AM_CFLAGS can be used in Makefile.am to set C compiler flags * Support for latest autoconf, including support for objext * Can now put `.' in SUBDIRS to control build order * `include' command and `+=' support for macro assignment * Dependency tracking no long susceptible to deleted header file problem * Maintainer mode now a conditional. @MAINT@ is now an anachronism. * Bug fixes New in 1.3: * Bug fixes * Better Cygwin32 support * Support for suffix rules with _SOURCES variables * New options `readme-alpha' and `check-news'; Gnits mode sets these * @LEXLIB@ no longer required when lex source seen Lex support in `missing', and new lex macro. Update your missing script. * Built-in support for assembly * aclocal gives error if `AM_' macro not found * Passed YFLAGS, not YACCFLAGS, to yacc * AM_PROG_CC_STDC does not have to come before AC_PROG_CPP * Dependencies computed as a side effect of compilation * Preliminary support for Java * DESTDIR support at "make install" time * Improved ansi2knr support; you must use the latest ansi2knr.c (included) New in 1.2: * Bug fixes * Better DejaGNU support * Added no-installinfo option * Added Emacs Lisp support * Added --no-force option * Included `aclocal' program * Automake will now generate rules to regenerate aclocal.m4, if appropriate * Now uses `AM_' macro names everywhere * ansi2knr option can have directory prefix (eg `../lib/ansi2knr') ansi2knr now works correctly on K&R sources * Better C++, yacc, lex support * Will compute _DEPENDENCIES variables automatically if not supplied * Will interpolate $(...) and ${...} when examining contents of a variable * .deps files now in build directory, not source directory; dependency handling generally rewritten * DATA, MANS and BUILT_SOURCES no longer included in distribution * can now put config.h into a subdir * Added dist-all target * Support for install-info program (see texinfo 3.9) * Support for "yacc -d" * configure substitutions are automatically discovered and included in generated Makefile.in * Special --cygnus mode * OMIT_DEPENDENCIES can now hold list of dependencies to be omitted when making distribution. Some dependencies are auto-ignored. * Changed how libraries are specified in _LIBRARIES variable * Full libtool support, from Gord Matzigkeit * No longer have to explicitly touch stamp-h when using AC_CONFIG_HEADER; AM_CONFIG_HEADER handles it automatically * Texinfo output files no longer need .info extension * Added `missing' support * Cygwin32 support * Conditionals in Makefile.am, from Ian Taylor New in 1.0: * Bug fixes * distcheck target runs install and installcheck targets * Added preliminary support for DejaGNU. New in 0.33: * More bug fixes * More checking * More libtool fixes from Gord Matzigkeit; libtool support is still preliminary however * Added support for jm_MAINTAINER_MODE * dist-zip support * New "distcheck" target New in 0.32: * Many bug fixes * mkinstalldirs and mdate-sh now appear in directory specified by AC_CONFIG_AUX_DIR. * Removed DIST_SUBDIRS, DIST_OTHER * AC_ARG_PROGRAM only required when an actual program exists * dist-hook target now run before distribution packaged up; idea from Dieter Baron. Other hooks exist, too. * Preliminary (unfinished) support for libtool * Added short option names. * Better "dist" support when gluing together multiple packages New in 0.31: * Bug fixes * Documentation updates (many from Fran
