It is possible that there is something strange with my Xcode though as I keep it updated and have installed all additional components, I would be surprised. Potentially it can be a version difference (11.3.1 (11C504).
The difference between GNU ang CLANG might not be so strange, it likely the case that I included the -mpi and -openmpi with gnu while missing the -mpi flag with CLANG as openmpi is not supported by clang. Sorry for mixing up inputs and outputs.
Best regards
