[llvm-dev] error in building llvm with default options

[Kókai Péter via llvm-dev]

Hello,

I cannot tell you if this is due to ram, but I had ram issue with 32
GB + 16 core when build with default options (clang was around 1 GB
binary), you could try to enable shared libraries(BUILD_SHARED_LIBS).
In that case I did not run into out of memory kind of issues.
