[cfe-dev] Can't compile clang

[Chris Lee]

Hi Ted,

Yeah, I had an old checkout of the normal llvm tree from svn (from a  
few weeks ago) in there, but the clang compile instructions didn't  
actually say that I needed to run 'make' in the llvm tree... so I  
didn't.

I did 'make libs-only' and then re-tried 'make' in the tools/clang  
dir, and that worked great! Having fun playing with it now. :)

Thanks!

-Chris
