Description Jack Jansen 2009-11-05 14:20:22 UTC 
I'm building "fat" SDL 1.3 libraries for MacOSX, but now I am running into the issue that audio does not work on PowerPC macintoshes if you build the library on an Intel.

The problem is that configure hard-codes the byteorder, which is then stored in SDL_config.h:
---------------
dnl Detect the canonical build and host environments
dnl AC_CANONICAL_HOST
AC_C_BIGENDIAN
if test x$ac_cv_c_bigendian = xyes; then
    AC_DEFINE(SDL_BYTEORDER, 4321)
else
    AC_DEFINE(SDL_BYTEORDER, 1234)
fi
----------------

What is really needed to enable ppc/intel builds is something like
#if __LITTLE_ENDIAN__
#define SDL_BYTEORDER 1234
#else
#define SDL_BYTEORDER 4321
#endif

I have no idea whether this can be integrated in the SDL (maybe through a configure option?), but it would be welcome if it could!

This should be fixed in revision 5224.  Thanks!
