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
