Error for 'make'

Hello,
I want to write my own plug-in. So when i tried to execute the PrintFumctionNames plug-in in llvm/tools/clang/examples/PrintFumctionNames i’m getting an error at first step of ‘make’ only. The error is :

akash@ubuntu:~/llvm/tools/clang/examples/PrintFunctionNames$ make

…/…/…/…/Makefile.common:60: …/…/…/…/Makefile.config: No such file or directory
…/…/…/…/Makefile.common:68: /Makefile.rules: No such file or directory
make: *** No rule to make target `/Makefile.rules’. Stop.

So how to get out with it please help me.
Tnks…!!!

(Whoops.)
