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
