* Major changes in Autoconf 2.59 -*- outline -*- Released 2003-11-04, by Akim Demaille ** ac_abs_builddir etc. Absolute paths were actually relative in 2.58. * Major changes in Autoconf 2.58 Released 2003-11-04, by Akim Demaille ** core.* core.* files are no longer removed, as they may be valid user files. ** autoreconf and auxiliary directory Autoreconf creates the auxiliary directory if needed. This is especially useful for initial "bootstrapping" of fresh CVS checkouts. ** AC_CONFIG_MACRO_DIR Use this macro to declare the directory for local m4 macros for aclocal. ** AC_LIBOBJS No longer includes twice the same file in LIBOBJS if invoked multiple times. ** AC_CONFIG_COMMANDS The directory for its first argument is automatically created. For instance, with AC_CONFIG_COMMANDS([src/modules.hh], [...]) $top_builddir/src/ is created if needed. ** Autotest and local.at The optional file local.at is always included in Autotest test suites. ** Warnings The warnings are always issued, including with cached runs. This became a significant problem since aclocal and automake can run autoconf behind the scene. ** autoheader warnings The warnings of autoheader can be turned off, using --warning. For instance, -Wno-obsolete disables the complaints about acconfig.h and other deprecated constructs. ** New macros AC_C_RESTRICT, AC_INCLUDES_DEFAULT, AC_LANG_ASSERT, AC_LANG_WERROR, AS_SET_CATFILE. ** AC_DECL_SYS_SIGLIST Works again. ** AC_FUNC_MKTIME Now checks that mktime is the inverse of localtime. ** Improve DJGPP portability The Autoconf tools and configure behave better under DJGPP. ** Present But Cannot Be Compiled New FAQ section dedicated to the mystic configure: WARNING: pi.h: present but cannot be compiled configure: WARNING: pi.h: check for missing prerequisite headers? configure: WARNING: pi.h: proceeding with the preprocessor's result messages. ** Concurrent executions of autom4te autom4te now locks its internal files, which enables concurrent executions of autom4te, likely to happen if automake, autoconf, autoheader etc. are run simultaneously. ** Libtool Use of Libtool 1.5 and higher is encouraged. Compatibility with Libtool pre-1.4 is not checked. ** Autotest Testsuites no longer rerun failed tests in verbose mode; instead, failures are logged while the test is run. In addition, expected failures can be marked as such. |
