  Thanks for your help. Now I have another problem,

llvm[4]: Compiling Version.cpp for Release build
/nfs_home/chenwj/install/bin/clang++: /usr/lib/gcc/x86_64-pc-linux-gnu/4.4.2/libstdc++.so.6: version `GLIBCXX_3.4.14' not found
(required by /nfs_home/chenwj/install/bin/clang++)

  What does the error mean? My default gcc is GCC 4.4.2, and its'
libstdc++.so has no GLIBCXX_3.4.14. The GCC 4.5.2's libstdc++.so
does have though. I find the comments of the post [1] have the
similar problem I have, but I am not sure if this is the correct
way to slove above problem.
