PROGRAM is typically a program composed via # AC_LANG_PROGRAM(). PROGRAM may be omitted if you are interested only # in learning if the compiler or linker respects certain flags. LANGUAGE # is typically either C or C++ and specifies which compiler to use for # the test. If LANGUAGE is omitted, C is used. FLAGS is a whitespace # delimited list of build tuples. Tuples are created with # CS_CREATE_TUPLE() and are composed of up to three elements each. The # first element represents compiler flags, the second linker flags, and # the third libraries used when linking the program. Each tuple from # FLAGS is attempted in order. If you want a build attempted with no # special flags prior to builds with specialized flags, create an empty # tuple with CS_CREATE_TUPLE() at the start of the FLAGS list. If the # build is successful, then the shell variables cs_build_ok is set to # "yes", cs_build_cflags, cs_build_lflags, and cs_build_libs are set to # the tuple elements which resulted in the successful build, and # ACTION-IF-BUILT is invoked. Upon successful build, no further tuples # are consulted. If no tuple results in a successful build, then # cs_build_ok is set to "no" and ACTION-IF-NOT-BUILT is invoked. # OTHER-CFLAGS, OTHER-LFLAGS, and OTHER-LIBS specify additional compiler # flags, linker flags, and libraries which should be used with each tuple # build attempt. Upon successful build, these additional flags are also # reflected in the variables cs_build_cflags, cs_build_lflags, and # cs_build_libs unless INHIBIT-OTHER-FLAGS is a non-empty string. The # optional ERROR-REGEX places an additional constraint upon the build # check. If specified, ERROR-REGEX, which is a standard `grep' regular # expression, is applied to output captured from the compiler and linker. # If ERROR-REGEX matches, then the build is deemed a failure, and # cs_build_ok is set to "no". This facility is useful for broken build # tools which emit an error message yet still return success as a result. # In such cases, it should be possible to detect the failure by scanning # the tools' output. # # IMPLEMENTATION NOTES # # In Autoconf 2.57 and earlier, AC_LINK_IFELSE() invokes AC_TRY_EVAL(), # which does not provide access to the captured output. To work around # this limitation, we temporarily re-define AC_TRY_EVAL() as # _AC_EVAL_STDERR(), which leaves the captured output in conftest.err # (which we must also delete). In Autoconf 2.58, however, # AC_LINK_IFELSE() instead already invokes _AC_EVAL_STDERR() on our # behalf, however we must be careful to apply ERROR-REGEX within the # invocation AC_LINK_IFELSE(), since AC_LINK_IFELSE() deletes # conftest.err before it returns. #------------------------------------------------------------------------------ AC_DEFUN([CS_BUILD_IFELSE], [AC_LANG_PUSH(m4_default([$3],[C])) cs_cflags_save="$CS_LANG_CFLAGS" cs_lflags_save="$LDFLAGS" cs_libs_save="$LIBS" cs_build_ok=no m4_ifval([$10], [m4_pushdef([AC_TRY_EVAL], [_AC_EVAL_STDERR]($$[1]))]) for cs_build_item in m4_default([$2],[CS_CREATE_TUPLE()]) do CS_SPLIT_TUPLE( [$cs_build_item],[cs_cflags_test,cs_lflags_test,cs_libs_test]) CS_LANG_CFLAGS="$cs_cflags_test $6 $cs_cflags_save" LDFLAGS="$cs_lflags_test $7 $cs_lflags_save" LIBS="$cs_libs_test $8 $cs_libs_save" AC_LINK_IFELSE(m4_default([$1], [AC_LANG_PROGRAM([],[])]), [m4_ifval([$10], [AS_IF([AC_TRY_COMMAND( [grep "AS_ESCAPE([$10])" conftest.err >/dev/null 2>&1])], [cs_build_ok=no], [cs_build_ok=yes])], [cs_build_ok=yes])]) AS_IF([test $cs_build_ok = yes], [break]) done m4_ifval([$10], [m4_popdef([AC_TRY_EVAL]) rm -f conftest.err]) CS_LANG_CFLAGS=$cs_cflags_save LDFLAGS=$cs_lflags_save LIBS=$cs_libs_save AC_LANG_POP(m4_default([$3],[C])) AS_IF([test $cs_build_ok = yes], [cs_build_cflags=CS_TRIM([$cs_cflags_test[]m4_ifval([$9],[],[ $6])]) cs_build_lflags=CS_TRIM([$cs_lflags_test[]m4_ifval([$9],[],[ $7])]) cs_build_libs=CS_TRIM([$cs_libs_test[]m4_ifval([$9],[],[ $8])]) $4], [$5])]) #------------------------------------------------------------------------------ # CS_CHECK_BUILD(MESSAGE, CACHE-VAR, [PROGRAM], [FLAGS], [LANGUAGE], # [ACTION-IF-BUILT], [ACTION-IF-NOT-BUILT], [IGNORE-CACHE], # [OTHER-CFLAGS], [OTHER-LFLAGS], [OTHER-LIBS], # [INHIBIT-OTHER-FLAGS], [ERROR-REGEX]) # Like CS_BUILD_IFELSE() but also prints "checking" and result messages, # and optionally respects the cache.
