To elaborate a bit more on this (cause it bit me a few weeks ago): On x86_64, the $(NATIVE_ARCH) macro expands to i386. This is documented in the Xcode 3.0 release notes (I think) to maintain compatibility with older Xcode projects. Otherwise you'd open an Xcode 2.5 project in Xcode 3.0 and get different behavior. Nowadays $(NATIVE_ARCH_ACTUAL) is the macro you want to use for "no, really, I want 64-bit if you can do it". --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
