It would seem peculiar to have no Fortran compiler installed. Even if that was the case at the moment, it could change in the future, and you would not want to have to rebuild MPI in that case.
It is not peculiar. LLVM does not yet have a usable Fortran front-end, so anyone that uses this compiler toolchain exclusively does not have a Fortran compiler.
I understand that is being resolved.
ETA for Fortran 2008 support is how many years?
When I build MPICH with LLVM, I do a pure build, wherein CC=clang, CXX=clang++ FC=false. This means that my MPI library cannot know anything about Fortran and I do not want it to make stuff up.
LLVM is the system compiler for a relatively large computer company known as Apple, and many HPC users own such systems :-)
True, but not for running MPI applications.
I run MPI+Clang apps on Mac regularly. Note also that at least one of the BSDs switched from GCC to LLVM for license purity. Jeff
