Yes actually, I don’t want openmp to be disabled globally like this. I’ll take a look but currently I’m busy with something else .

Well, without either including portgroup mpi - and/or adding dependencies for critical components like libomp, etc - how do you expect OpenMP to work?

On a separate note, there's another build failure affecting 10.15. That was just addressed with the latest force-push, along with an update to b4508.

I am think about adding compiler.openmp* stuff to this port, but as I said I’ll need a few days. Your update and patch for 10.15 is great tho and can be merged now.
