Hi Sam,
After I remove the /usr/include path.
5 kinds of errors dispear. But there is still one error left,
/sandbox/xiuxia/llvm_build/Debug+Asserts/lib/clang/3.4/include/mm_malloc.h:27:10:
fatal error: 'stdlib.h' file not found.
stdlib is under /usr/include , and it include lots of other heads which is
also located in /usr/include.
Thanks,
Xiuxia
