	checking Mac OS X headers by Vincent Torri-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Hey, I would like to check if some Mac OS X headers are available. So I first set the Objective C compiler with AC_LANG_PUSH, only if there is an Objective C compiler: # Check compilers m4_ifdef([AC_PROG_OBJC], [ AC_PROG_OBJC _AM_DEPENDENCIES(OBJC) ], [ AC_CHECK_TOOL([OBJC], [gcc]) AC_SUBST([OBJC]) AC_SUBST([OBJCFLAGS]) ] ) AC_PROG_CXX AC_PROG_CC # check header m4_ifdef([AC_PROG_OBJC], [AC_LANG_PUSH([Objective C])], []) AC_CHECK_HEADERS([/System/Library/Frameworks/Cocoa.framework/Headers/Cocoa.h], [have_dep="yes"], [have_dep="no"]) m4_ifdef([AC_PROG_OBJC], [AC_LANG_POP([Objective C])], []) But the configure script fails: configure: error: in `/home/torri/svnroot/evas': configure: error: Objective C preprocessor "/lib/cpp" fails sanity check I have looked at config.log but it does not help a lot. Does someone see where I'm wrong ? thank you Vincent Torri _______________________________________________ Autoconf mailing list Autoconf@... http://lists.gnu.org/mailman/listinfo/autoconf

Will you allow us to have a look at it? (IOW, please post it.)

Solution is to install the respective frontend. Cheers, Ralf _______________________________________________ Autoconf mailing list Autoconf@... http://lists.gnu.org/mailman/listinfo/autoconf

I would like to check the Mac OS X header only if an Objective C compiler is present, as i have to use an objective c compiler (hance the AC_LANG_PUSH in the code). But it seems that the use of m4_ifdef is not sufficient. do you have an idea of how to do that ?

I'd be inclined to just AC_CHECK_HEADERS([Cocoa/Cocoa.h]) Framework style includes like that should work with all Mac OS X compilers.

Besides the answer Peter already gave you, which is probably the right thing for you, finding out whether the Objective C compiler can compile and link code should be possible as follows (untested): AC_LANG_PUSH([Objective C]) AC_MSG_CHECKING([whether then Objective C compiler works]) AC_LINK_IFELSE([AC_LANG_PROGRAM([])], [AC_MSG_RESULT([yes])], [AC_MSG_RESULT([no])]) AC_LANG_POP([Objective C]) Similar with AC_RUN_IFELSE if you require a run test (but take care of the cross-compile scenario in that case).
