[Openmp-dev] Building OpenMP on Mac usiing Clang

[Abid Malik via Openmp-dev]

Hello,

I am trying to build OpenMP for LLVM on Mac. I was able to
successfully build Clang from the source. However, I am getting the
following error message during the OpenMP build: I used the my own Clang
(the one I build) for OpenML build

make
