Building clang in xcode.

How do i build clang in xcode? I opened llvm.xcodeproj and built it for ALL_BUILD target. It built everything except clang.

I was planning to step through clang code using xcode.

Do you have the clang folder placed in /llvm/tools ?
So there should be a path /llvm/tools/clang.

If you then invoke cmake to generate a xcode project
and build all targets within xcode it should build clang too.

What parts of llvm are build depends on which "subprojects" are
contained in your llvm tree. The folders have to be placed and named correctly.

You can check them out with svn like presented here: or download them from the release page: LLVM Download Page
