If no INCLUDES are specified, the default includes are used. If ACTION-IF-SIGNED is given, it is additional shell code to execute when the type is signed. If ACTION-IF-UNSIGNED is given, it is executed when the type is unsigned. This macro assumes that the type exists. Therefore the existence of the type should be checked before calling this macro. For example: AC_CHECK_HEADERS([wchar.h]) AC_CHECK_TYPE([wchar_t],,[ AC_MSG_ERROR([Type wchar_t not found.]) ]) AX_CHECK_SIGN([wchar_t], [ AC_DEFINE(WCHAR_T_SIGNED, 1, [Define if wchar_t is signed]) ], [ AC_DEFINE(WCHAR_T_UNSIGNED, 1, [Define if wchar_t is unsigned]) ], [ #ifdef HAVE_WCHAR_H #include #endif ]) Source Code *********** Download the latest version of 'ax_check_sign.m4' (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_sign.m4) or browse the macro's revision history (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_sign.m4).

See if we need to substitute. To make this work, you have to do horrible things. In one of your Makefile.am files, you must make an explicit rule to make this object. It should look like this: strcspn.lo : $(top_srcdir)/compat/strcspn.c $(LTCOMPILE) -o $@ -c $(top_srcdir)/compat/strcspn.c and you must include "@COMPATOBJ@" in a LIBADD somewhere and, finally, you must add another artificial dependency, something like: makeshell.lo : genshell.c @COMPATOBJ@ It is all pretty horrific, but I have found nothing else that works.

Version scripts are used when building shared libraries to bind symbols to version nodes (helping to detect incompatibilities) or to limit the visibility of non-public symbols. Output: If version scripts are supported, VSCRIPT_LDFLAGS will contain the appropriate flag to pass to the linker. On GNU systems this would typically be "-Wl,-version-script", and on Solaris it would typically be "-Wl,-M". Two Automake conditionals are also set: HAVE_VSCRIPT is true if the linker supports version scripts with entries that use simple wildcards, like "local: *". HAVE_VSCRIPT_COMPLEX is true if the linker supports version scripts with pattern matching wildcards, like "global: Java_*". On systems that do not support symbol versioning, such as Mac OS X, both conditionals will be false. They will also be false if the user passes "-disable-symvers" on the configure command line. Example: configure.ac: AX_CHECK_VSCRIPT Makefile.am: if HAVE_VSCRIPT libfoo_la_LDFLAGS += $(VSCRIPT_LDFLAGS),@srcdir@/libfoo.map endif if HAVE_VSCRIPT_COMPLEX libbar_la_LDFLAGS += $(VSCRIPT_LDFLAGS),@srcdir@/libbar.map endif Source Code *********** Download the latest version of 'ax_check_vscript.m4' (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_vscript.m4) or browse the macro's revision history (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_vscript.m4).

If the instruction set is supported by the host cpu, the C preprocessor macro HAVE_XXX_INSTRUCTIONS is set to 1. The XXX is up-cased instruction case with dot replaced by underscore. For example, the test for "sse4.2" would export HAVE_SSE4_2_INSTRUCTIONS=1. Also the compiler flag "-msse4.2" would be added to X86_FEATURE_CFLAGS variable, that can be obtained in Makefile.am using @X86_FEATURE_CFLAGS@. If any of the test for the instruction set were succeeded, the configure script would run ACTION-IF-FOUND if it is specified, or append X86_FEATURE_CFLAGS to CFLAGS. If none of the instruction were found, ACTION-IF-NOT-FOUND hook is triggered. This macro requires gcc extended builtin function "__builtin_cpu_init" and "__builtin_cpu_supports" to detect the cpu features. It will error out if the compiler doesn't has these builtins. See also AX_GCC_X86_CPU_SUPPORTS, which is the actual macro that perform the checks for the instruction sets.

If nothing was specified when calling configure, it searches first in /usr/local and then in /usr, /opt/local and /sw. If the -with-zlib=DIR is specified, it will try to find it in DIR/include/zlib.h and DIR/lib/libz.a. If -without-zlib is specified, the library is not searched at all. If either the header file (zlib.h) or the library (libz) is not found, shell commands 'action-if-not-found' is run. If 'action-if-not-found' is not specified, the configuration exits on error, asking for a valid zlib installation directory or -without-zlib. If both header file and library are found, shell commands 'action-if-found' is run. If 'action-if-found' is not specified, the default action appends '-I${ZLIB_HOME}/include' to CPFLAGS, appends '-L$ZLIB_HOME}/lib' to LDFLAGS, prepends '-lz' to LIBS, and calls AC_DEFINE(HAVE_LIBZ). You should use autoheader to include a definition for this symbol in a config.h file. Sample usage in a C/C++ source is as follows: #ifdef HAVE_LIBZ #include #endif /* HAVE_LIBZ */ Source Code *********** Download the latest version of 'ax_check_zlib.m4' (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_check_zlib.m4) or browse the macro's revision history (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_check_zlib.m4).

Also add rules using AX_ADD_AM_MACRO_STATIC; and $enable_code_coverage which can be used in subsequent configure output. CODE_COVERAGE_ENABLED is defined and substituted, and corresponds to the value of the -enable-code-coverage option, which defaults to being disabled. Test also for gcov program and create GCOV variable that could be substituted. Note that all optimization flags in CFLAGS must be disabled when code coverage is enabled. Usage example: configure.ac: AX_CODE_COVERAGE Makefile.am: include $(top_srcdir)/aminclude_static.am my_program_LIBS = ... $(CODE_COVERAGE_LIBS) ... my_program_CPPFLAGS = ... $(CODE_COVERAGE_CPPFLAGS) ... my_program_CFLAGS = ... $(CODE_COVERAGE_CFLAGS) ... my_program_CXXFLAGS = ... $(CODE_COVERAGE_CXXFLAGS) ... clean-local: code-coverage-clean distclean-local: code-coverage-dist-clean This results in a "check-code-coverage" rule being added to any Makefile.am which do "include $(top_srcdir)/aminclude_static.am" (assuming the module has been configured with -enable-code-coverage). Running 'make check-code-coverage' in that directory will run the module's test suite ('make check') and build a code coverage report detailing the code which was touched, then print the URI for the report. This code was derived from Makefile.decl in GLib, originally licensed under LGPLv2.1+.

File: autoconf-archive.info, Node: ax_compare_version, Next: ax_compile_check_sizeof, Prev: ax_code_coverage, Up: The Macros ax_compare_version ================== Synopsis ******** AX_COMPARE_VERSION(VERSION_A, OP, VERSION_B, [ACTION-IF-TRUE], [ACTION-IF-FALSE]) Description *********** This macro compares two version strings. Due to the various number of minor-version numbers that can exist, and the fact that string comparisons are not compatible with numeric comparisons, this is not necessarily trivial to do in a autoconf script. This macro makes doing these comparisons easy. The six basic comparisons are available, as well as checking equality limited to a certain number of minor-version levels. The operator OP determines what type of comparison to do, and can be one of: eq - equal (test A == B) ne - not equal (test A != B) le - less than or equal (test A <= B) ge - greater than or equal (test A >= B) lt - less than (test A < B) gt - greater than (test A > B) Additionally, the eq and ne operator can have a number after it to limit the test to that number of minor versions. eq0 - equal up to the length of the shorter version ne0 - not equal up to the length of the shorter version eqN - equal up to N sub-version levels neN - not equal up to N sub-version levels When the condition is true, shell commands ACTION-IF-TRUE are run, otherwise shell commands ACTION-IF-FALSE are run. The environment variable 'ax_compare_version' is always set to either 'true' or 'false' as well. Examples: AX_COMPARE_VERSION([3.15.7],[lt],[3.15.8]) AX_COMPARE_VERSION([3.15],[lt],[3.15.8]) would both be true. AX_COMPARE_VERSION([3.15.7],[eq],[3.15.8]) AX_COMPARE_VERSION([3.15],[gt],[3.15.8]) would both be false. AX_COMPARE_VERSION([3.15.7],[eq2],[3.15.8]) would be true because it is only comparing two minor versions. AX_COMPARE_VERSION([3.15.7],[eq0],[3.15]) would be true because it is only comparing the lesser number of minor versions of the two values. Note: The characters that separate the version numbers do not matter. An empty string is the same as version 0. OP is evaluated by autoconf, not configure, so must be a string, not a variable. The author would like to acknowledge Guido Draheim whose advice about the m4_case and m4_ifvaln functions make this macro only include the portions necessary to perform the specific comparison specified by the OP argument in the final configure script.

You can supply extra HEADERS to look into. the check will cycle through 1 2 4 8 16 and any EXTRA_SIZES the user supplies. If a match is found, it will #define SIZEOF_'TYPE' to that value. Otherwise it will emit a configure time error indicating the size of the type could not be determined. The trick is that C will not allow duplicate case labels. While this is valid C code: switch (0) case 0: case 1:; The following is not: switch (0) case 0: case 0:; Thus, the AC_COMPILE_IFELSE will fail if the currently tried size does not match.

Return the value in the variable $ax_enable_compile_warnings. Depending on the value of -enable-compile-warnings, different compiler warnings are checked to see if they work with the current compiler and, if so, are appended to CFLAGS-VARIABLE and LDFLAGS-VARIABLE. This allows a consistent set of baseline compiler warnings to be used across a code base, irrespective of any warnings enabled locally by individual developers. By standardising the warnings used by all developers of a project, the project can commit to a zero-warnings policy, using -Werror to prevent compilation if new warnings are introduced. This makes catching bugs which are flagged by warnings a lot easier. By providing a consistent -enable-compile-warnings argument across all projects using this macro, continuous integration systems can easily be configured the same for all projects. Automated systems or build systems aimed at beginners may want to pass the -disable-Werror argument to unconditionally prevent warnings being fatal. -enable-compile-warnings can take the values: * no: Base compiler warnings only; not even -Wall. * yes: The above, plus a broad range of useful warnings. * error: The above, plus -Werror so that all warnings are fatal. Use --disable-Werror to override this and disable fatal warnings. The set of base and enabled flags can be augmented using the EXTRA-*-CFLAGS and EXTRA-*-LDFLAGS variables, which are tested and appended to the output variable if -enable-compile-warnings is not "no". Flags should not be disabled using these arguments, as the entire point of AX_COMPILER_FLAGS is to enforce a consistent set of useful compiler warnings on code, using warnings which have been chosen for low false positive rates. If a compiler emits false positives for a warning, a #pragma should be used in the code to disable the warning locally. See: https://gcc.gnu.org/onlinedocs/gcc-4.9.2/gcc/Diagnostic-Pragmas.html#Diagnostic-Pragmas The EXTRA-* variables should only be used to supply extra warning flags, and not general purpose compiler flags, as they are controlled by configure options such as -disable-Werror. IS-RELEASE can be used to disable -Werror when making a release, which is useful for those hairy moments when you just want to get the release done as quickly as possible. Set it to "yes" to disable -Werror. By default, it uses the value of $ax_is_release, so if you are using the AX_IS_RELEASE macro, there is no need to pass this parameter. For example: AX_IS_RELEASE([git-directory]) AX_COMPILER_FLAGS() CFLAGS-VARIABLE defaults to WARN_CFLAGS, and LDFLAGS-VARIABLE defaults to WARN_LDFLAGS. Both variables are AC_SUBST-ed by this macro, but must be manually added to the CFLAGS and LDFLAGS variables for each target in the code base. If C++ language support is enabled with AC_PROG_CXX, which must occur before this macro in configure.ac, warning flags for the C++ compiler are AC_SUBST-ed as WARN_CXXFLAGS, and must be manually added to the CXXFLAGS variables for each target in the code base. EXTRA-*-CFLAGS can be used to augment the base and enabled flags. Warning flags for g-ir-scanner (from GObject Introspection) are AC_SUBST-ed as WARN_SCANNERFLAGS. This variable must be manually added to the SCANNERFLAGS variable for each GIR target in the code base. If extra g-ir-scanner flags need to be enabled, the AX_COMPILER_FLAGS_GIR macro must be invoked manually. AX_COMPILER_FLAGS may add support for other tools in future, in addition to the compiler and linker. No extra EXTRA-* variables will be added for those tools, and all extra support will still use the single -enable-compile-warnings configure option. For finer grained control over the flags for individual tools, use AX_COMPILER_FLAGS_CFLAGS, AX_COMPILER_FLAGS_LDFLAGS and AX_COMPILER_FLAGS_* for new tools. The UNUSED variables date from a previous version of this macro, and are automatically appended to the preceding non-UNUSED variable. They should be left empty in new uses of the macro.

This function iterates over these triplets and set $RESULT to the relative path from $FROM to $TO. Note that $FROM and $TO needs to be absolute filenames for this macro to success. For instance, first=/usr/local/bin second=/usr/local/share AX_COMPUTE_RELATIVE_PATHS([first:second:fs second:first:sf]) # $fs is set to ../share # $sf is set to ../bin $FROM and $TO are both eval'ed recursively and normalized, this means that you can call this macro with autoconf's dirnames like 'prefix' or 'datadir'. For example: AX_COMPUTE_RELATIVE_PATHS([bindir:datadir:bin_to_data]) AX_COMPUTE_RELATIVE_PATHS should also works with DOS filenames. You may want to use this macro in order to make your package relocatable. Instead of hardcoding $datadir into your programs just encode $bin_to_data and try to determine $bindir at run-time. This macro requires AX_NORMALIZE_PATH and AX_RECURSIVE_EVAL.

Ahhm, did you see ax_path_generic in the autoconf-archive? ;-) this macros saves you all the typing for a pkg-config.in script, you don't even need to distribute one along. Place this macro in your configure.ac, et voila, you got one that you want to install. oh, btw, if the first arg looks like "mylib -lwhat' then it will go to be added to the -libs, and mylib is extracted. the defaults: $1 = $PACKAGE $LIBS $2 = $VERSION there is also an AC_SUBST(GENERIC_CONFIG) that will be set to the name of the file that we did output in this macro. Use as: install-exec-local: install-generic-config install-generic-config: $(mkinstalldirs) $(DESTDIR)$(bindir) $(INSTALL_SCRIPT) @GENERIC_CONFIG@ $(DESTDIR)$(bindir) Source Code *********** Download the latest version of 'ax_create_generic_config.m4' (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_create_generic_config.m4) or browse the macro's revision history (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_create_generic_config.m4).

PACKAGE_LIBS defaults to -l$PACKAGE_NAME if not set. The resulting file is called $PACKAGE.pc.in / $PACKAGE.pc You will find this macro most useful in conjunction with ax_spec_defaults that can read good initializers from the .spec file. In consequence, most of the generatable installable stuff can be made from information being updated in a single place for the whole project.

File: autoconf-archive.info, Node: ax_create_stdint_h, Next: ax_create_target_h, Prev: ax_create_pkgconfig_info, Up: The Macros ax_create_stdint_h ================== Synopsis ******** AX_CREATE_STDINT_H [( HEADER-TO-GENERATE [, HEDERS-TO-CHECK])] Description *********** the "ISO C9X: 7.18 Integer types " section requires the existence of an include file that defines a set of typedefs, especially uint8_t,int32_t,uintptr_t. Many older installations will not provide this file, but some will have the very same definitions in . In other environments we can use the inet-types in which would define the typedefs int8_t and u_int8_t respectively. This macros will create a local "_stdint.h" or the headerfile given as an argument. In many cases that file will just "#include " or "#include ", while in other environments it will provide the set of basic 'stdint's definitions/typedefs: int8_t,uint8_t,int16_t,uint16_t,int32_t,uint32_t,intptr_t,uintptr_t int_least32_t.. int_fast32_t.. intmax_t which may or may not rely on the definitions of other files, or using the AC_CHECK_SIZEOF macro to determine the actual sizeof each type. if your header files require the stdint-types you will want to create an installable file mylib-int.h that all your other installable header may include. So if you have a library package named "mylib", just use AX_CREATE_STDINT_H(mylib-int.h) in configure.ac and go to install that very header file in Makefile.am along with the other headers (mylib.h) - and the mylib-specific headers can simply use "#include " to obtain the stdint-types. Remember, if the system already had a valid , the generated file will include it directly. No need for fuzzy HAVE_STDINT_H things... (oops, GCC 4.2.x has deliberately disabled its stdint.h for non-c99 compilation and the c99-mode is not the default. Therefore this macro will not use the compiler's stdint.h - please complain to the GCC developers).

File: autoconf-archive.info, Node: ax_create_target_h, Next: ax_cvs, Prev: ax_create_stdint_h, Up: The Macros ax_create_target_h ================== Synopsis ******** AX_CREATE_TARGET_H [(HEADER-FILE [,PREFIX)] Description *********** Create the header-file and let it contain '#defines' for the target platform. This macro is used for libraries that have platform-specific quirks. Instead of inventing a target-specific target.h.in files, just let it create a header file from the definitions of AC_CANONICAL_SYSTEM and put only ifdef's in the installed header-files. if the HEADER-FILE is absent, [target.h] is used. if the PREFIX is absent, [TARGET] is used. the prefix can be the packagename. (y:a-z-:A-Z_:) The defines look like... #ifndef TARGET_CPU_M68K #define TARGET_CPU_M68K "m68k" #endif #ifndef TARGET_OS_LINUX #define TARGET_OS_LINUX "linux-gnu" #endif #ifndef TARGET_OS_TYPE /* the string itself */ #define TARGET_OS_TYPE "linux-gnu" #endif Detail: in the case of hppa1.1, the three idents "hppa1_1" "hppa1" and "hppa" are derived, for an m68k it just two, "m68k" and "m". The CREATE_TARGET_H__ variant is almost the same function, but everything is lowercased instead of uppercased, and there is a "__" in front of each prefix, so it looks like... #ifndef __target_os_linux #define __target_os_linux "linux-gnulibc2" #endif #ifndef __target_os__ /* the string itself */ #define __target_os__ "linux-gnulibc2" #endif #ifndef __target_cpu_i586 #define __target_cpu_i586 "i586" #endif #ifndef __target_arch_i386 #define __target_arch_i386 "i386" #endif #ifndef __target_arch__ /* cpu family arch */ #define __target_arch__ "i386" #endif Other differences: the default string-define is "__" instead of "_TYPE". Personally, I prefer the second variant (which had been the first in the devprocess of this file but I assume people will often fallback to the primary variant presented herein). NOTE: CREATE_TARGET_H does also fill HOST_OS-defines Functionality has been split over functions called CREATE_TARGET_H_UPPER, CREATE_TARGET_H_LOWER, CREATE_TARGET_HOST_UPPER, and CREATE_TARGET_HOST_LOWER. CREATE_TARGET_H uses CREATE_TARGET_H_UPPER CREATE_TARGET_HOST_UPPER CREATE_TARGET_H_ uses CREATE_TARGET_H_LOWER CREATE_TARGET_HOST_LOWER There is now a CREATE_PREFIX_TARGET_H in this file as a shorthand for PREFIX_CONFIG_H from a target.h file, however w/o the target.h ever created (the prefix is a bit different, since we add an extra -target- and -host-).

Branching and releasing relies on you using the following version format: MAJOR.MINOR.POINT where MAJOR is the major version number, MINOR is the minor version number and POINT is the point release number. make update performs a cvs update make commitlog Generates a ChangeLog template with the modified, added and removed files and opens it up for editing. This is not normally used directly, but is instead called by commit. It is useful however if you want to document the work you have done, but don't want to commit just yet. make commit performs a cvs commit after first performing a cvs update and generating a commit log. make cvs-rm FILES="file1 file2 ..." removes a file or files specified by the FILES variable from the file system and from cvs. It will interactively ask you to confirm the file removal, unless the file does not exist on the file system. make cvs-add FILES="file1 file2 ..." adds a file or files specified by the FILES variable to cvs. make branch-major creates a branch based on the major version number, increments the major version number, sets the minor and point versions to zero and checks out the branch into a new directory. make branch-minor creates a branch based on the minor version number, increments the minor version, sets the point version to zero number and checks out the branch into a new directory. make release performs a cvs update, followed by a distcheck, then creates a release for the current version, increments the point release number and checks out the release into a new directory make quick-release same as release, but distcheck is not performed Source Code *********** Download the latest version of 'ax_cvs.m4' (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_cvs.m4) or browse the macro's revision history (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_cvs.m4).

If necessary, add switches to CXX and CXXCPP to enable support. VERSION may be '11' (for the C++11 standard) or '14' (for the C++14 standard). The second argument, if specified, indicates whether you insist on an extended mode (e.g. -std=gnu++11) or a strict conformance mode (e.g. -std=c++11). If neither is specified, you get whatever works, with preference for no added switch, and then for an extended mode. The third argument, if specified 'mandatory' or if left unspecified, indicates that baseline support for the specified C++ standard is required and that the macro should error out if no mode with that support is found. If specified 'optional', then configuration proceeds regardless, after defining HAVE_CXX${VERSION} if and only if a supporting mode is found.

Conformant behavior is to have global destructors after atexit Per Paragraph 3.6.3/1 of the C++11 Standard: Destructors (12.4) for initialized objects [..] with static storage duration are called as a result of returning from main and as a result of calling std::exit (18.5). And per Paragraph 3.6.3/3: If the completion of the initialization of an object with static storage duration is sequenced before a call to std::atexit [..], the call to the function passed to std::atexit is sequenced before the call to the destructor for the object. WARNING: If cross-compiling, the test cannot be performed, the default action is to define HAVE_DTOR_AFTER_ATEXIT.

File: autoconf-archive.info, Node: ax_define_sub_path, Next: ax_dirname, Prev: ax_define_integer_bits, Up: The Macros ax_define_sub_path ================== Synopsis ******** AX_DEFINE_SUB_PATH(DEFNAME, varname, description) Description *********** Look at varname and detect the subpath that it contains relative to $prefix/$exec_prefix. If the path is indeed relative to $prefix/$exec_prefix, then a single "./" (dotslash) is prepended, otherwise it can be seen as an absolute path that cannot be moved, which you possibly do for "/etc" files, or even those ending up in "/lib/modules" or "/winnt/system". This macro is not very intelligent, it's just a first try in this direction. It does currently just look into the current patterns, and replaces a ${prefix} with a simple dot. Amazingly, it works quite well for most packages. Example (configure.ac): AX_DEFINE_DIR([EPREFIX], [exec_prefix], [--exec-prefix or default]) AX_DEFINE_SUB_PATH([PATH_LIBDIR], [libdir], [--bindir subdir]) AC_DEFINE_UNQUOTED([PACKAGE],"$PACKAGE", [Name of package]) Example (in C): static const char _libdir[] = PATH_LIBDIR; /* configure default */ char* libdir; char* eprefix = getenv (PACKAGE "DIR"); if (! eprefix) eprefix = EPREFIX; /* default */ if (*_libdir != '.') libdir = strdup(_libdir); else { libdir = malloc(strlen(eprefix) + strlen(_libdir) + 2); strcpy(libdir, eprefix); strcat(libdir, PATH_DELIMITER_STRING); strcat(libdir, _libdir); } ... free (libdir); The AX_DEFINE_SUB_PATHS(varnames) macro looks for the given various install-paths that largely depend on either ${prefix} or ${exec_prefix}. Just cut out the prefix and ac_define the value. The value is uppercased and PATH_ prepended ie. ax_define_sub_paths(bindir libdir pkgdatadir) will create the defines PATH_BINDIR PATH_LIBDIR PATH_PKGDATADIR - see posix' include/paths.h that creates _PATH_DEV and friends.

This means you MUST have the shell variable EMACS set to a valid Emacs executable prior to the first call to any of the AX_ELISP_CHECK et al macros. Those work by saving their results to the file defined by calling AX_ELISP_CONFIG_FILE so you MUST call that prior, too. For example: dnl Arrange to save config answers in $top_builddir/lisp/config.el. AX_ELISP_CONFIG_FILE([lisp/config.el]) dnl Set shell variable EMACS and AC_SUBST it, too. dnl (NB: This is a separate Autoconf Archive macro.) AX_PROG_EMACS In the following detailed descriptions, SYMBOL stands for an Emacs Lisp symbol, which may contain hyphens, e.g., 'define-error' or 'org-src'. Likewise, FEATURE is an Emacs Lisp symbol (naming a feature). BODY and SUCCESS-EXPR are Emacs Lisp forms, zero or more for BODY and exactly one for SUCCESS-EXPR. In these forms you must take care to avoid apostrophe (U+27). Instead of 'foo, write (quote foo). * AX_ELISP_CONFIG_FILE(FILENAME) This arranges for future AX_ELISP_CHECK (et al) calls to save their results in FILENAME. May be called multiple times. FILENAME should be relative to the top build dir. * AX_ELISP_CHECK(SYMBOL,DESCRIPTION,BODY,SUCCESS-EXPR) This is the general macro that the other AX_ELISP_CHECK* macros use. It constructs a short Emacs Lisp file comprising BODY and evaluates it via $EMACS -batch -Q. The exit value of this script depends on the result of evaluating SUCCESS-EXPR: non-nil is success and nil is failure. On success, append SYMBOL on a line of its own to the config file. This macro uses AC_CACHE_CHECK and passes DESCRIPTION to it. * AX_ELISP_CHECK_FEATURE(FEATURE) This checks if (require (quote FEATURE)) is successful. If so, add featurep-FEATURE to the config file (NB the "featurep-" prefix). * AX_ELISP_CHECK_FBOUNDP(SYMBOL,[FEATURE [...]]) This checks if (fboundp (quote SYMBOL)) is successful. If so, append SYMBOL to the config file. Optional 2nd arg is a space-separated list of features to require prior to the fboundp check. * AX_ELISP_CHECK_BOUNDP(SYMBOL,[FEATURE [...]]) This checks if (boundp (quote SYMBOL)) is successful. If so, append SYMBOL to the config file. Optional 2nd arg is a space-separated list of features to require prior to the boundp check.

We provide an option -disable-builddir to suppress the move into a separate builddir. Defaults: $1 = $host (overridden with $HOST) $2 = Makefile.mk $3 = -all This macro must be called before AM_INIT_AUTOMAKE. It creates a default toplevel srcdir Makefile from the information found in the created toplevel builddir Makefile. It just copies the variables and rule-targets, each extended with a default rule-execution that recurses into the build directory of the current "HOST". You can override the auto-detection through 'config.guess' and build-time of course, as in make HOST=i386-mingw-cross which can of course set at configure time as well using configure --host=i386-mingw-cross After the default has been created, additional rules can be appended that will not just recurse into the subdirectories and only ever exist in the srcdir toplevel makefile - these parts are read from the $2 = Makefile.mk file The automatic rules are usually scanning the toplevel Makefile for lines like '#### $host |$builddir' to recognize the place where to recurse into. Usually, the last one is the only one used. However, almost all targets have an additional "*-all" rule which makes the script to recurse into _all_ variants of the current HOST (!!) setting. The "-all" suffix can be overridden for the macro as well. a special rule is only given for things like "dist" that will copy the tarball from the builddir to the sourcedir (or $(PUB)) for reason of convenience.

It has been observed that it was done wrong over and over again, so this is a bit more safe to do. remember - setting exec_prefix='${prefix}' needs you interpolate directories multiple times, it is not sufficient to just say MYVAR="${datadir}/putter" but you do have to run 'eval' a few times, sth. like MYVAR='eval "echo \"$MYVAR\""' done at least two times. The implementation of this macro simply picks up the lines that would be run at the start of AC_OUTPUT anyway to set the prefix/exec_prefix defaults. Between AC_INIT and the first command to AC_REQUIRE this macro you can set the two variables to something explicit instead.

File: autoconf-archive.info, Node: ax_extend_srcdir, Next: ax_extra_dist, Prev: ax_ext_have_lib, Up: The Macros ax_extend_srcdir ================ Synopsis ******** AX_EXTEND_SRCDIR Description *********** The AX_EXTEND_SRCDIR macro extends $srcdir by one path component. As an example, when working in /home/michael/i3-4.12/build and calling ../configure, your $srcdir is "..". After calling AX_EXTEND_SRCDIR, $srcdir will be set to "../../i3-4.12". The result of extending $srcdir is that filenames (e.g. in the output of the "backtrace" gdb command) will include one more path component of the absolute source path. The additional path component makes it easy for users to recognize which files belong to the PACKAGE, and - provided a dist tarball was unpacked - which version of PACKAGE was used. As an example, in "backtrace", you will see: #0 main (argc=1, argv=0x7fffffff1fc8) at ../../i3-4.12/src/main.c:187 instead of: #0 main (argc=1, argv=0x7fffffff1fc8) at ../src/main.c:187 In case your code uses the __FILE__ preprocessor directive to refer to the filename of the current source file (e.g. in debug messages), using the extended path might be undesirable. For this purpose, AX_EXTEND_SRCDIR defines the output variable AX_EXTEND_SRCDIR_CPPFLAGS, which can be added to AM_CPPFLAGS in Makefile.am in order to define the preprocessor directive STRIPPED__FILE__. As an example, when compiling the file "../../i3-4.12/src/main.c", STRIPPED__FILE__ evaluates to "main.c". There are some caveats: When $srcdir is "." (i.e. when ./configure was called instead of ../configure in a separate build directory), AX_EXTEND_SRCDIR will still extend $srcdir, but the intended effect will not be achieved because of the way automake specifies file paths: automake defines COMPILE to use "'test -f '$source' || echo '\$(srcdir)/''$source" in order to prefer files in the current directory over specifying $srcdir explicitly. The AX_EXTEND_SRCDIR author is not aware of any way to influence this automake behavior. Patches very welcome. To work around this issue, you can use AX_ENABLE_BUILDDIR i.e. by adding the following code to configure.ac: AX_ENABLE_BUILDDIR dnl ... AX_EXTEND_SRCDIR Then also add this bit to Makefile.am (if you wish to use STRIPPED__FILE__ in your code): AM_CPPFLAGS = @AX_EXTEND_SRCDIR_CPPFLAGS@ Source Code *********** Download the latest version of 'ax_extend_srcdir.m4' (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=blob_plain;f=m4/ax_extend_srcdir.m4) or browse the macro's revision history (http://git.savannah.gnu.org/gitweb/?p=autoconf-archive.git;a=history;f=m4/ax_extend_srcdir.m4).

On some systems, notably the Alpha with Compaq compilers, the Fortran libraries have their own main() function which must be disabled. Runs ACTION-IF-SUCCEED if successful, and ACTION-IF-FAIL if not. Defines the output variable F77_CMAIN_FFLAGS to any discovered flags. (If ACTION-IF-FAIL is not specified, defaults to halting with an error.) This macro is especially useful in conjunction with automake, since by default automake uses $F77 to link programs mixing C and Fortran, leading to a link error on some systems. In this case, you should set the FFLAGS for that program to include F77_CMAIN_FFLAGS.

If found, the cache variable $ax_cv_gcc_archflag is set to this flag and ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is set to "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is to add $ax_cv_gcc_archflag to the end of $CFLAGS. PORTABLE? should be either [yes] (default) or [no]. In the former case, the flag is set to -mtune (or equivalent) so that the architecture is only used for tuning, but the instruction set used is still portable. In the latter case, the flag is set to -march (or equivalent) so that architecture-specific instructions are enabled. The user can specify -with-gcc-arch= in order to override the macro's choice of architecture, or -without-gcc-arch to disable this. When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is called unless the user specified -with-gcc-arch manually. Requires macros: AX_CHECK_COMPILE_FLAG, AX_GCC_X86_CPUID (The main emphasis here is on recent CPUs, on the principle that doing high-performance computing on old hardware is uncommon.)

The BUILTIN parameter is the name of the built-in function. If BUILTIN is supported define HAVE_. Keep in mind that since builtins usually start with two underscores they will be copied over into the HAVE_ definition (e.g. HAVE___BUILTIN_EXPECT for __builtin_expect()). The macro caches its result in the ax_cv_have_ variable (e.g. ax_cv_have___builtin_expect). The macro currently supports the following built-in functions: __builtin_assume_aligned __builtin_bswap16 __builtin_bswap32 __builtin_bswap64 __builtin_choose_expr __builtin___clear_cache __builtin_clrsb __builtin_clrsbl __builtin_clrsbll __builtin_clz __builtin_clzl __builtin_clzll __builtin_complex __builtin_constant_p __builtin_cpu_init __builtin_cpu_is __builtin_cpu_supports __builtin_ctz __builtin_ctzl __builtin_ctzll __builtin_expect __builtin_ffs __builtin_ffsl __builtin_ffsll __builtin_fpclassify __builtin_huge_val __builtin_huge_valf __builtin_huge_vall __builtin_inf __builtin_infd128 __builtin_infd32 __builtin_infd64 __builtin_inff __builtin_infl __builtin_isinf_sign __builtin_nan __builtin_nand128 __builtin_nand32 __builtin_nand64 __builtin_nanf __builtin_nanl __builtin_nans __builtin_nansf __builtin_nansl __builtin_object_size __builtin_parity __builtin_parityl __builtin_parityll __builtin_popcount __builtin_popcountl __builtin_popcountll __builtin_powi __builtin_powif __builtin_powil __builtin_prefetch __builtin_trap __builtin_types_compatible_p __builtin_unreachable Unsupported built-ins will be tested with an empty parameter set and the result of the check might be wrong or meaningless so use with care.

Compiler warnings are used to detect supported attributes as unsupported ones are ignored by default so quieting warnings when using this macro will yield false positives. The ATTRIBUTE parameter holds the name of the attribute to be checked. If ATTRIBUTE is supported define HAVE_FUNC_ATTRIBUTE_. The macro caches its result in the ax_cv_have_func_attribute_ variable. The macro currently supports the following function attributes: alias aligned alloc_size always_inline artificial cold const constructor constructor_priority for constructor attribute with priority deprecated destructor dllexport dllimport error externally_visible fallthrough flatten format format_arg gnu_format gnu_inline hot ifunc leaf malloc noclone noinline nonnull noreturn nothrow optimize pure sentinel sentinel_position unused used visibility warning warn_unused_result weak weakref Unsupported function attributes will be tested with a prototype returning an int and not accepting any arguments and the result of the check might be wrong or meaningless so use with care.

The instruction set that can be tested are "mmx, popcnt, sse, sse2, sse3, sse4.1, sse4.2, sse4a, avx, avx2, avx512f, fma, fma4, bmi, bmi2". If the instruction set is supported by the host cpu, the C preprocessor macro HAVE_XXX_INSTRUCTIONS is set to 1. The XXX is up-cased instruction case with dot replaced by underscore. For example, the test for "sse4.2" would export HAVE_SSE4_2_INSTRUCTIONS=1. This macro requires gcc extended builtin function "__builtin_cpu_init" and "__builtin_cpu_supports" to detect the cpu features. It will error out if the compiler doesn't has these builtins. If the test for the instruction set succeeded, the hook ACTION-IF-FOUND would run. Otherwise the hook ACTION-IF-NOT-FOUND would run if specified.

Currently, the only supported VCS is git, but support for others could be added in future. Defines GENERATE_CHANGELOG_RULES which should be substituted in your Makefile. Usage example: configure.ac: AX_GENERATE_CHANGELOG Makefile.am: @GENERATE_CHANGELOG_RULES@ CHANGELOG_START = 0.2.3^ dist-hook: dist-ChangeLog ChangeLog (stub committed to VCS): The ChangeLog is auto-generated when releasing. If you are seeing this, use 'git log' for a detailed list of changes. This results in a "dist-ChangeLog" rule being added to the Makefile. When run, "dist-ChangeLog" will generate a ChangeLog in the $(top_distdir), using $(CHANGELOG_GIT_FLAGS) to format the output from "git log" being run in $(CHANGELOG_GIT_DIR). Unless Automake is initialised with the 'foreign' option, a dummy ChangeLog file must be committed to VCS in $(top_srcdir), containing the text above (for example). It will be substituted by the automatically generated ChangeLog during "make dist".

File: autoconf-archive.info, Node: ax_gnu_autotest, Next: ax_have_adns, Prev: ax_generate_changelog, Up: The Macros ax_gnu_autotest =============== Synopsis ******** AX_GNU_AUTOTEST([testdir = `tests'], [testsuites = `testsuite'], [atlocal-sources = `'], [gen-package = `yes'], [force = `no']) Description *********** Sets up one or multiple GNU Autotest test suites [1]. TL;DR: * Write tests/testsuite.at as normal * Add to configure.ac: AX_GNU_AUTOTEST * Add to Makefile.am or Makefile.in in top_srcdir: @AX_GNU_AUTOTEST_DEFAULT@ * autoreconf && ./configure && make check GNU Autotest is a very powerful testing framework to script executing binaries, observing their output and logging failures, all in the same portable manner as configure itself. But the only help given the developer in setting up the framework is the AC_CONFIG_TESTDIR() command, which leaves several additional steps up to the developer copying examples from the manual: * generating the "package.m4" file used in generating the "testsuite" * generating the "testsuite" executable by calling autom4te * adding Makefile rules to keep both "package.m4" and "testsuite" current * figuring out how to do all the above if the Makefile does not reside in the testdir This command takes care of all of the above. It is designed to be called multiple times for different testdir directories, to have multiple testsuites scripts per directory and to handle the optional "package.m4" and "atlocal" (re)generation. The various actions taken by this command happen in different phases of the build process: 1) During the autoconf execution, generate the testsuites and any "package.m4" files. So these are already available before configure ran. The reasoning for deviating from the examples in [1] is that these files are distributed and must be placed in the srcdir: it seems cleaner to not generate anything in srcdir during any of the later phases. 2) During the config.status execution (following the configure execution), generate "atconfig" and any "atlocal" files in the buildir. The "atconfig" generation is handled by calling AC_CONFIG_TESTDIR() so the developer does not have to do so themselves. 3) During the execution of make, several additional rules and file lists are made available via AC_SUBST(). The rules are intended to be called where appropriate (e.g. make check can depend on check-autotest) and the file lists are intended to be added to the appropriate lists (i.e. to DISTCLEANFILES and EXTRA_DIST). Description of AX_GNU_AUTOTEST() arguments: * testdir: directory-name containing the testsuites. AX_GNU_AUTOTEST() must be called exactly once for each directory containing testsuites. If empty, defaults to "tests". * testsuites: space-separated list of words, where each word is the name of a test suite script optionally followed by a colon and the name of the scripts source file. If the source file is not given, it defaults to the script name suffixed by ".at". So these words are all equivalent: "foo", "foo:" and "foo:foo.at". If the argument is empty, it defaults to "testsuite". The script filenames must not contain any path, but that is allowed for the source filenames. * atlocal-sources: space- or colon-separated list of filenames, which are registered with AC_CONFIG_FILES() as the sources of atlocal. If empty, no atlocal file is generated. * gen-package: boolean ("yes" or "no") indicating whether "package.m4" should be generated. If empty, defaults to "yes". * force: boolean ("yes" or "no") whether to treat errors in arguments as errors and abort (for "no") or whether to ignore any such errors (for "yes"). If empty, defaults to "no". All filenames above must be relative. The testdir name is interpreted relative to top_srcdir. All other names are interpreted relative to the testdir. The boolean values are interpreted as "yes" for any non-empty value except "0", "n", "no" and their mixed-case variants. Description of Makefile.am / Makefile.in substitutions: * AX_GNU_AUTOTEST_RULES: the make rules provided here. Substitute this in a separate line. * AX_GNU_AUTOTEST_DCLEAN: the list of files to be added to DISTCLEANFILES. * AX_GNU_AUTOTEST_DIST: the list of files to be added to EXTRA_DIST. * AX_GNU_AUTOTEST_DEFAULT: includes all other substitutions and uses them in a "default" way. All must be used as a substitution (@...@) instead of as a variable ($(...) or ${...}). These substitutions are generated multiple times, once for each directory where an affected Makefile may be located. All substitutions start with the base as given above but may have suffixes for the directories. Assuming this example in configure.ac: AX_GNU_AUTOTEST([foo/bar]) AX_GNU_AUTOTEST([baz]) Then the following substitutions are available (where stands for one of the above prefixes): * : for use in top_srcdir/Makefile * _foo : for use in top_srcdir/foo/Makefile * _foo_bar : for use in top_srcdir/foo/bar/Makefile * _baz : for use in top_srcdir/baz/Makefile The substitutions cover both foo/bar and baz, so none of the other substitutions should be used. Indeed, no Makefiles are needed in the other directories. But if sub-directory Makefiles are used, then both _baz and either of _foo or _foo_bar must be used in their respective Makefiles. Description of Makefile targets defined by AX_GNU_AUTOTEST_RULES*: * check-autotest: The equivalent of check. * installcheck-autotest: The equivalent of installcheck. * clean-autotest: The equivalent of clean. The developer can either define the above targets as dependencies of their appropriate equivalent rule or of their *-local equivalent rule for automake or they can define a rule with a sub-make call as they wish. All rules are dependent on like-named rules for each sub-directory and for each testsuite. Only the testsuite rules actually do any work, the rest are just collectors and convenience names. Assuming this example in configure.ac: AX_GNU_AUTOTEST([foo], [testsuite bar]) AX_GNU_AUTOTEST([baz]) Then AX_GNU_AUTOTEST_RULES defines these check rules (likewise for installcheck and clean): check-autotest: check-autotest-foo check-autotest-baz check-autotest-foo: check-autotest-foo-testsuite check-autotest-foo-bar check-autotest-baz: check-autotest-baz-testsuite check-autotest-foo-testsuite # Executes foo/testsuite -C foo check-autotest-foo-bar # Executes foo/bar -C foo check-autotest-baz-testsuite # Executes baz/testsuite -C baz And AX_GNU_AUTOTEST_RULES_baz defines these check rules: check-autotest: check-autotest-testsuite check-autotest-testsuite # Executes testsuite (which is baz/testsuite) Note how the rule names only contain the directory and testsuite paths relative to the Makefile location. Also note how each testsuite is executed in its respective testdir. In addition to the above, AX_GNU_AUTOTEST_RULES* also contains the rules to keep the testsuites, "package.m4" and "atconfig" updated. The matching rules to keep "atlocal" updated are generated by automake if that is used or are the responsibility of the developer. All testsuite executions (except for clean) use variables AX_GNU_AUTOTEST_FLAGS, AX_GNU_AUTOTEST_CHECK_FLAGS, AX_GNU_AUTOTEST_INSTALLCHECK_FLAGS and more path-and-script-specific variants for additional command line options. These variables can be defined by the developer to pass options to the testsuite. In the example above, the rule check-autotest-foo-bar would look like this: check-autotest-foo-bar: foo/bar -C foo $(AX_GNU_AUTOTEST_FLAGS) \ $(AX_GNU_AUTOTEST_CHECK_FLAGS) \ $(AX_GNU_AUTOTEST_FLAGS_foo) \ $(AX_GNU_AUTOTEST_CHECK_FLAGS_foo) \ $(AX_GNU_AUTOTEST_FLAGS_foo_bar) \ $(AX_GNU_AUTOTEST_CHECK_FLAGS_foo_bar) Description of Makefile file lists: These lists are intended to be added to DISTCLEANFILES and EXTRA_DIST. The *_DCLEAN list contains all "atconfig" files and the *_DIST list contains all testsuites and "package.m4" files. The lists are again generated per directory: so AX_GNU_AUTOTEST_DCLEAN contains all "atconfig" files while e.g. AX_GNU_AUTOTEST_DIST_foo contains only files below the "foo" directory. These file lists are prevented from becoming Makefile variables by calling AM_SUBST_NOTMAKE(): that way, only the single version used by the Makefile is substituted, not all lists for all other paths as well. So use either like this: DISTCLEANFILES = @AX_GNU_AUTOTEST_DCLEAN@ EXTRA_DIST = @AX_GNU_AUTOTEST_DIST_foo@ Or like this: AX_GNU_AUTOTEST_DCLEAN_foo = @AX_GNU_AUTOTEST_DCLEAN_foo@ AX_GNU_AUTOTEST_DIST_foo = @AX_GNU_AUTOTEST_DIST_foo@ DISTCLEANFILES = ${AX_GNU_AUTOTEST_DCLEAN_foo} EXTRA_DIST = ${AX_GNU_AUTOTEST_DIST_foo} Description of shorthand default Makefile contents defined by AX_GNU_AUTOTEST_DEFAULT*: This shorthand defines the appropriate rules, adds the file lists to the proper variables and makes the new targets dependencies of the standard "check", "installcheck" and "clean" targets. AX_GNU_AUTOTEST_DEFAULT is for example equivalent to: @AX_GNU_AUTOTEST_RULES@ check: check-autotest installcheck: installcheck-autotest clean: clean-autotest distclean: distclean-autotest distclean-autotest: clean-autotest -rm -f @AX_GNU_AUTOTEST_DCLEAN@ .PHONY: distclean-autotest EXTRA_DIST += @AX_GNU_AUTOTEST_DIST@ Note that this is copied verbatim into the Makefile (after expansion of the contained @...@ substitutions): it does not shadow the default targets as would happen if the same lines were written in a Makefile.am file. And also note the use of the += operator: this will not be compatible with all versions of Make. Finally, the DISTCLEANFILES list is not used because automake only uses that list if it saw the variable in the Makefile.am file: in a substitution, it gets ignored unless the user already used the list.
