[cfe-dev] fatal error: 'features.h' file not found

Hi All, 

I am trying to compile the cloud9, when the application try to compile the LLVM it gives me error like this :

COMPILE:   clang_linux/full-i386/i386: /home/krishan/cloud9/src/third_party/llvm/projects/compiler-rt/lib/enable_execute_stack.c

Please help me to solve this problem. Since it's using gclient to perform the auto compiling, I cannot change anything. Does any have installed cloud9 ?

PS : The features.h file is in the /usr/include directory, but why the compiler couldn't get it ? is that my library path got screwed it up?
 

Thank-you

Krish
