Did you install Open MPI via Homebrew? I don’t think this will work (at least, I have yet to see a single person make it work with the recent changes with Apple linker). I would: 1) remove all this unnecessary stuff CXX_LINKER_FLAGS=-Wl,-rpath,/opt/homebrew/lib CFLAGS="-g -O2 -fPIC" CXXFLAGS="-g -O2 -fPIC" FCFLAGS="-g -O2" FFLAGS="-g -O2" LDFLAGS="-Wl,-ld_classic -Wl,-commons,use_dylibs" MAKEFLAGS=w These are either: default parameters or low-level parameters that are likely to break stuff if not set appropriately. 2) add something like --download-mpich or --download-openmpi to your configure options 3) start fresh by removing your previous PETSC_ARCH directory
