[cfe-dev] Linker error while building clang

[Mahesha S]

Hi all,

I am a newbie to llvm world. Today, I tried to build Clang ( and llvm) by
exactly following the instruction as given in the link
http://clang.llvm.org/get_started.html. But, I am getting the following
linker error. It would be great if anybody help me in resolving this issue.
