I am trying to configure v 4.1 with the following, which fails as noted in the Subject line.
./configure --prefix=/Users/Shared/openmpi410 \ FC=gfortran CC=clang CXX=c++ --disable-static \ 2>&1 | tee openmpi-config.out On a 2019 MacbookPro with 10.15 (but I had the same problem with 10.14). Gfortran (and gcc) is from High Performance Computing for OSX Any clues will be gratefully received! And I apologize if this is a solved problem ... Many thanks, Tony Rollett PS. If I try “CC=gcc CXX=g++” then it fails at the C compilation stage.
