thank you for your super fast reply.
I am following "Installation_clang_4.docx" when I run ~/build-llvm/llvm$ ninja in one-hour building process reach to 377 [377/2141] Build CXX object ....... and then those number did not increase from 377 and Ubuntu stopped to work. I tried several times but OS stopped.
Computer properties:
Intel(R) Core(TM) i5-6400 CPU 2.70 GHz
Ram: 8 GB

Actually today I tried again to build ninja but...
