Universal Binary supporting i386, x86_64 and PPC

Question

Can you build an OSX program supporting i386, x86_64 and PPC at the same time?

Answer 1

If you use Xcode, you don't have to use lipo, just list those architectures in the Architectures [ARCHS] build setting. Of course, you can't use Xcode 4, as it does not support ppc.

Answer 2

The answer would seem to be yes, you combine them all with the lipo tool.
