You can skip the lipo step, gcc will do it for you if you provide the right flags. You can also include 64-bit in there. If you want to do specific optimizations for each CPU, then you'll have to build each separately and use lipo to assemble them all into one.
CFLAGS="-arch i386 -arch ppc -arch x86_64 -arch ppc64" LDFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386 -arch ppc -arch x86_64 -arch ppc64" Pd-extended is not universal (yet?). I think it should be, it's just a matter of someone doing the work. .hc On Nov 25, 2007, at 5:49 PM, Alexandre Quessy wrote: > Thanks Thomas ! > Is this what is done in pd-extended ?
