Some configure.in files need minor adjustments to -work with it; the documentation has a chapter on upgrading. A few -configure.in files, including those for GNU Emacs and the GNU C -Library, need major changes because they relied on undocumented -internals of version 1. Future releases of those packages will have -updated configure.in files. - -It's best to use GNU m4 1.3 (or later) with Autoconf version 2. -Autoconf now makes heavy use of m4 diversions, which were implemented -inefficiently in GNU m4 releases before 1.3. - -Major changes in release 2.0: - -** New copyright terms: -* There are no restrictions on distribution or use of configure scripts. - -** Documentation: -* Autoconf manual is reorganized to make information easier to find - and has several new indexes. -* INSTALL is reorganized and clearer and is now made from Texinfo source. - -** New utilities: -* autoscan to generate a preliminary configure.in for a package by - scanning its source code for commonly used nonportable functions, - programs, and header files. -* ifnames to list the symbols used in #if and #ifdef directives in a - source tree. -* autoupdate to update a configure.in to use the version 2 macro names. -* autoreconf to recursively remake configure and configuration header - files in a source tree. - -** Changed utilities: -* autoheader can take pieces of acconfig.h to replace config.h.{top,bot}. -* autoconf and autoheader can look for package-local definition files - in an alternate directory. - -** New macros: -* AC_CACHE_VAL to share results of tests between configure runs. -* AC_DEFUN to define macros, automatically AC_PROVIDE them, and ensure - that macros invoked with AC_REQUIRE don't interrupt other macros. -* AC_CONFIG_AUX_DIR, AC_CANONICAL_SYSTEM, AC_CANONICAL_HOST, AC_LINK_FILES to - support deciding unguessable features based on the host and target types. -* AC_CONFIG_SUBDIRS to recursively configure a source tree. -* AC_ARG_PROGRAM to use the options --program-prefix, - --program-suffix, and --program-transform-name to change the names - of programs being installed. -* AC_PREFIX_DEFAULT to change the default installation prefix. -* AC_TRY_COMPILE to compile a test program without linking it. -* AC_CHECK_TYPE to check whether sys/types.h or stdlib.h defines a given type. -* AC_CHECK_LIB to check for a particular function and library. -* AC_MSG_CHECKING and AC_MSG_RESULT to print test results, on a single line, - whether or not the test succeeds. They obsolete AC_CHECKING and AC_VERBOSE. -* AC_SUBST_FILE to insert one file into another. -* AC_FUNC_MEMCMP to check whether memcmp is 8-bit clean. -* AC_FUNC_STRFTIME to find strftime even if it's in -lintl. -* AC_FUNC_GETMNTENT to find getmntent even if it's in -lsun or -lseq. -* AC_HEADER_SYS_WAIT to check whether sys/wait.h is POSIX.1 compatible. - -** Changed macros: -* Many macros renamed systematically, but old names are accepted for - backward compatibility. -* AC_OUTPUT adds the "automatically generated" comment to - non-Makefiles where it finds @configure_input@ in an input file, to - support files with various comment syntaxes. -* AC_OUTPUT does not replace "prefix" and "exec_prefix" in generated - files when they are not enclosed in @ signs. -* AC_OUTPUT allows the optional environment variable CONFIG_STATUS to - override the file name "config.status". -* AC_OUTPUT takes an optional argument for passing variables from - configure to config.status. -* AC_OUTPUT and AC_CONFIG_HEADER allow you to override the input-file names. -* AC_OUTPUT automatically substitutes the values of CFLAGS, CXXFLAGS, - CPPFLAGS, and LDFLAGS from the environment. -* AC_PROG_CC and AC_PROG_CXX now set CFLAGS and CXXFLAGS, respectively. -* AC_PROG_INSTALL looks for install-sh or install.sh in the directory - specified by AC_CONFIG_AUXDIR, or srcdir or srcdir/.. or - srcdir/../.. by default. -* AC_DEFINE, AC_DEFINE_UNQUOTED, and AC_SUBST are more robust and smaller. -* AC_DEFINE no longer prints anything, because of the new result reporting - mechanism (AC_MSG_CHECKING and AC_MSG_RESULT). -* AC_VERBOSE pays attention to --quiet/--silent, not --verbose. -* AC_ARG_ENABLE and AC_ARG_WITH support whitespace in the arguments to - --enable- and --with- options. -* AC_CHECK_FUNCS and AC_CHECK_HEADERS take optional shell commands to - execute on success or failure. -* Checking for C functions in C++ works. - -** Removed macros: -* AC_REMOTE_TAPE and AC_RSH removed; too specific to tar and cpio, and - better maintained with them. -* AC_ARG_ARRAY removed because no one was likely using it. -* AC_HAVE_POUNDBANG replaced with AC_SYS_INTERPRETER, which doesn't - take arguments, for consistency with all of the other specific checks. - -** New files: -* Comes with config.sub and config.guess, and uses them optionally. -* Uses config.cache to cache test results. An alternate cache file - can be selected with the --cache-file=FILE option. -* Uses optional shell scripts $prefix/share/config.site and - $prefix/etc/config.site to perform site or system specific initializations. -* configure saves compiler output to ./config.log for debugging. -* New files autoconf.m4 and autoheader.m4 load the other Autoconf macros. -* acsite.m4 is the new name for the system-wide aclocal.m4. -* Has a DejaGnu test suite. - -Major changes in release 1.11: - -* AC_PROG_INSTALL calls install.sh with the -c option. -* AC_SET_MAKE cleans up after itself. -* AC_OUTPUT sets prefix and exec_prefix if they weren't set already. -* AC_OUTPUT prevents shells from looking in PATH for config.status. - -Plus a few other bug fixes. - -Major changes in release 1.10: - -* autoheader uses config.h.bot if present, analogous to config.h.top. -* AC_PROG_INSTALL looks for install.sh in srcdir or srcdir/.. and - never uses cp. -* AC_PROG_CXX looks for cxx as a C++ compiler. - -Plus several bugs fixed. - -Major changes in release 1.9: - -* AC_YYTEXT_POINTER replaces AC_DECLARE_YYTEXT. -* AC_SIZEOF_TYPE generates the cpp symbol name automatically, - and autoheader generates entries for those names automatically. -* AC_FIND_X gets the result from xmkmf correctly. -* AC_FIND_X assumes no X if --without-x was given. -* AC_FIND_XTRA adds libraries to the variable X_EXTRA_LIBS. -* AC_PROG_INSTALL finds OSF/1 installbsd. -

AC_SET_MAKE, AC_ENABLE. - -** Changed macros: -* AC_FIND_X looks for X in more places. -* AC_PROG_INSTALL defaults to install.sh instead of cp, if it's in srcdir. - install.sh is distributed with Autoconf. -* AC_DECLARE_YYTEXT has been removed because it can't work, pending - a rewrite of quoting in AC_DEFINE. -* AC_OUTPUT adds its comments in C format when substituting in C files. -* AC_COMPILE_CHECK protects its ECHO-TEXT argument with double quotes. - -** New or changed command line options: -* configure accepts --enable-FEATURE[=ARG] and --disable-FEATURE options. -* configure accepts --without-PACKAGE, which sets withval=no. -* configure accepts --x-includes=DIR and --x-libraries=DIR. -* Giving --with-PACKAGE no argument sets withval=yes instead of withval=1. -* configure accepts --help, --version, --silent/--quiet, --no-create options. -* configure accepts and ignores most other Cygnus configure options, and - warns about unknown options. -* config.status accepts --help, --version options. - -** Paths and other changes: -* Relative srcdir values are not made absolute. -* The values of @prefix@ and @exec_prefix@ and @top_srcdir@ get substituted. -* Autoconf library files are installed in ${datadir}/autoconf, not ${datadir}. -* autoheader optionally copies config.h.top to the beginning of config.h.in. -* The example Makefile dependencies for configure et al. work better. -* Namespace cleanup: all shell variables used internally by Autoconf - have names beginning with `ac_'. - -More big improvements are in process for future releases, but have not -yet been (variously) finished, integrated, tested, or documented enough -to release yet. - -Major changes in release 1.7: - -* New macro AC_OBSOLETE. -* Bugs in Makefile.in fixed. -* AC_LONG_FILE_NAMES improved. - -Major changes in release 1.6: - -* New macro AC_LONG_64_BITS. -* Multiple .h files can be created. -* AC_FIND_X looks for X files directly if it doesn't find xmkmf. -* AC_ALLOCA defines C_ALLOCA if using alloca.c. -* --with-NAME can take a value, e.g., --with-targets=sun4,hp300bsd. -* Unused --no-create option to configure removed. -* autoheader doesn't change the timestamp of its output file if - the file didn't change. -* All macros that look for libraries now use AC_HAVE_LIBRARY. -* config.status checks three optional environment variables to - modify its behavior. -* The usual bug fixes. - -Major changes in release 1.5: - -* New macros AC_FIND_X, AC_OFF_T, AC_STAT_MACROS_BROKEN, AC_REVISION. -* autoconf and autoheader scripts have GNU standards conforming - --version and --help options (they print their message and exit). -* Many bug fixes. - -Major changes in release 1.4: - -* New macros AC_HAVE_POUNDBANG, AC_TIME_WITH_SYS_TIME, AC_LONG_DOUBLE, - AC_GETGROUPS_T, AC_DEFINE_UNQUOTED. -* autoconf and autoheader use the M4 environment variable to determine the - path of the m4 program to use. -* The --macrodir option to autoconf and autoheader specifies the directory - in which acspecific.m4, acgeneral.m4, etc. reside if not the default. -* autoconf and autoheader can take `-' as their file names, which means to - read stdin as input. -* Resulting configure scripts can take a --verbose option which causes them - to print the results of their tests. -* AC_DEFINE quotes its second argument in such a way that spaces, magic - shell characters, etc. will be preserved during various stages of - expansion done by the shell. If you don't want this, use - AC_DEFINE_UNQUOTED instead. -* Much textual processing done with external calls to tr and sed have been - internalized with builtin m4 `patsubst' and `translit' calls. -* AC_OUTPUT doesn't hardwire the filenames it outputs. Instead, you can - set the shell variables `gen_files' and `gen_config' to the list of - filenames to output. -* AC_DECLARE_YYTEXT does an AC_SUBST of `LEX_OUTPUT_ROOT', which may be - "lex.yy" or "lexyy", depending on the system. -* AC_PROGRAMS_CHECK takes an optional third arg. If given, it is used as - the default value. -* If AC_ALLOCA chooses alloca.c, it also defines STACK_DIRECTION. -* AC_CONST works much more reliably on more systems. -* Many bug fixes. - -Major changes in release 1.3: - -configure no longer requires awk for packages that use a config.h. -Support handling --with-PACKAGE options. -New `autoheader' script to create `config.h.in' from `configure.in'. -Ignore troublesome -lucb and -lPW when searching for alloca. -Rename --exec_prefix to --exec-prefix for GNU standards conformance. -Improve detection of STDC library. -Add AC_HAVE_LIBRARY to check for non-default libraries. -Function checking should work with future GNU libc releases. - -Major changes in release 1.2: - -The --srcdir option is now usually unnecessary. -Add a file containing sample comments describing CPP macros. -A comment in config.status tells which host it was configured on. -Substituted variable values can now contain commas. -Fix bugs in various feature checks. - -Major changes in release 1.1: - -Added AC_STRCOLL macro. -Made AC_GETLOADAVG check for more things. -AC_OUTPUT argument is now optional. -Various bug fixes. |
