So you can generate ppc and i386 files seperately? Try combining them with lipo -create I'm out of my element here, but my perusing of the lipo manual indicates this might work. -- -- arno s hautala /-\ fracai(a)mac.com -- -- _______________________________________________ Do not post admin requests to the list.

The problem I'm running into is that I need to pass specific flags for x86 to disable use of the SIMD registers by gcc (-mno-mmx -mno-sse -mno-sse2). Normally, you'd just do 'gcc -arch ppc -arch i386 foo.c', but the ppc stage of the compile pukes when I include the x86 SIMD exclusion flags.
