What binary architectures should be cross-compiled when building Mac OS X packages?
- by Alex Leach
Currently, Apple's native binaries and libraries are distributed as fat files, with support for both i386 and x86_64 architectures. The SDK (Xcode 4.4 w/ command line tools) doesn't support cross-compiling powerpc binaries any more, so they can be safely ignored I think, but there doesn't seem to be any specific guidelines or recommendations about which Intel architectures to support.
So, when compiling code for distribution on OS X, do people still cross-compile for the i386 architecture? Or are x86_64 binaries the only architecture worth bothering with nowadays?
