Unfortunately this is a known issue when using the default compiler setup on Mac OS.

What does work according to a student of mine who works on Apple:

– Use Homebrew to install tinyxml, zlib and GCC, set USE_EMBEDDED_DEPENDENCIES := OFF, adapt compiler paths to not use the Apple-provided compilers (this will work for sequential mode but not for OpenMPI due to a general issue on MacOS)
– Use Nix to provide the entire shell and execution environment (works for parallel execution using MPI)

We are currently working on a more detailed guide as we expect this same issue to come up in our upcoming Springschool. I will update this post once the guide is available.
