[LLVMdev] LLVM-GCC builds on OS X 10.5, fails on 10.6

[Jim Grosbach]

It looks like you're building a 32-bit llvm-gcc and trying to link it against 64-bit llvm libraries. Try specifying the triple as x86_64-apple-darwin10 instead of i686-apple-darwin9.

(LLVM itself builds fine on both platforms.) The build commands I'm using are identical, and I always start from a clean unpack of the version 2.8 tarball. However, the old laptop ran OS X 10.5 while the new one runs OS X 10.6. (There are other differences, but that is the most significant.)
