Hrm. I wanted to say that CMake should treat a Universal binary as
multiple targets. But if gcc treats them as a single target, that's not
possible. Sticky wicket. Suppress Endian checks on MacOS X?
Basically. Although you'll still need to check __BIG_ENDIAN__ on OSX;
so somewhere the code needs to know at preprocessor-time.
It's ugly, but this is what we used for dbus's (ew, autoconf) check:
---(snip!)---
## byte order
case $host_os in
darwin*)
# check at compile-time, so that it is possible to
build universal
# (with multiple architectures at once on the compile line)
AH_VERBATIM([WORDS_BIGENDIAN_DARWIN], [
/* Use the compiler-provided endianness
defines to allow universal compiling. */
#if defined(__BIG_ENDIAN__)
#define WORDS_BIGENDIAN 1
#endif
])
;;
*)
AC_C_BIGENDIAN
;;
esac
---(snip!)---
That goes right into config.h.
