I have successfully compiled the 3.6.1 version of LLVM-Clang-LLDB-Compiler-RT-LibCxx-LibCxxABI-TestSuite bundle. However, when I tried ninja check-all, the check failed right at the first target [1/150] Generating sanitizer_bitvector_test.cc.x86_64.o. I think the reason is that LLVM is trying to use the system GCC header files, but I compiled LLVM with another GCC toolchain (GCC 4.8.4) that I compiled and installed in a non-root directory. However, I can't figure out how to let the CMake avoid using the system GCC headers (I have modified the PATH and LD_LIBRARY_PATH, but they didn't help at all).
Here is the relevant information:
- CentOS 6.6
- x86_64 architecture (Intel(R) Xeon(R) CPU W3550 @ 3.07GHz)
- Tools used for installation:
- 1) gcc/4.8.4
- 2) ninja
- 3) zlib/1.2.8
- 4) python-miniconda
- Linux Kernel version
- 2.6.32-504.16.2.el6.x86_64

In particular you may notice that: /usr/lib/gcc/x86_64-redhat-linux/4.4.7/../../../../include/c++/4.4.7 was used. However, 'ninja check-all' really should have used the header files for gcc-4.8.4, not gcc-4.4.7 (system bundled gcc).
I have filed a bug report, but no one seems to want to answer it.
If anyone knows how to fix this, please let me know. Thanks.
