Hi,
Attached is a patch to add the correct option for building OpenMP code using
Clang. Per the llvm release notes
<http://llvm.org/releases/3.7.0/tools/clang/docs/ReleaseNotes.html> it is
necessary to give -fopenmp=libomp to build properly, not just -fopenmp. Tested
on 64-bit Linux using clang 3.7.0.
