Unsupported option '-fopenmp'\nclang

[Tom Goode]

Dear all,

I've been successfully running PyFR 1.6.0 on Ubuntu 16.04 but when I try to run PyFR 1.6.0 on a MacBook Pro with Sierra 10.12.4 I get an error which I have pasted below.

I came across a similar issue on this mailing list that suggested installing clang-omp with brew, but it appears the clang-omp package no longer exists. It seems to have been replaced by llvm but I think I am having trouble installing it properly as I get the same error as before. 

Has anybody else come across this problem? Any help would be greatly appreciated.

Kind regards,

Tom
