How do I install openmpi such that it is linked to gcc-9 in mac osx mojave?
First, I installed gcc-9 in macosx using the following command:
brew install gcc
Then, I installed openmpi using:
brew install openmpi
However, this openmpi is now linked to clang, which I don’t want to use at all.
I tried exporting HOMEBREW_CC=gcc-9 and HOMEBREW_CXX=g+±9, but this did not quite work since the ompi_info, shows:
C compiler: clang
C++ compiler: clang++
