[Juan Salazar]

Dear Pierre,

Indeed, many of the flags are unnecessary, but I was able to keep most of them. I inherited them from another group of developers that compile for linux. I’m the only one working to run this code natively on macOS. What I noticed is that if I pass LDFLAGS=-Wl,-ld_classic there are still duplicate LC_RPATH. However, with CXX_LINKER_FLAGS=-Wl,-ld_classic I get no duplicate LC_RPATH.

I indeed am usingOpenMPI via homebrew. But I was able to keep it.

Thanks!
Juan S.

This is because I compile OpenFOAM natively (it is developed for Linux, but with some tweaks it can be compiled on macOS). I use the PETSc library within custom OpenFOAM  applications (solvers). Therefore I install PETSc in the same volume.
