Thank you very much, Matt! That sounds like it. Will try when I next get to work on this. (and I would really like to make 5.0.0 work …)
(I lost a few extra hours afterwards, with the OneAPI based OpenMPI 4.1.6 mpic++ not being able to find various C++ headers - and I think this is due to Apple XCode. mpif90 and mpicc work and the situation for mpic++ did improve with XCode 5.1 beta 2, which is why I am suspecting this is an XCode related problem. However, I now need to find more time …) Thanks again & best wishes Volker Volker Blum Associate Professor, Duke MEMS & Chemistry https://aims.pratt.duke.edu https://bsky.app/profile/aimsduke.bsky.social > On Oct 28, 2023, at 1:32 PM, Matt Thompson <fort...@gmail.com> wrote: > > On my Mac I build Open MPI 5 with (among other flags): > > --with-hwloc=internal --with-libevent=internal --with-pmix=internal > > In my case, I should have had libevent through brew, but it didn't seem to > see it.
