Use --with-fc=gfortran instead /opt/ohpc/pub/spack/opt/spack/linux-centos7-skylake_avx512/gcc-8.3.0/m4-1.4.19-lwqcw3hzoxoia5q6nzolylxaf5zevluk/bin/m4: internal error detected; please report this bug to <bug...@gnu.org>: Illegal instruction You might need to report this to your admin who installed this spack package. They might need to rebuild spack for 'x86_64' instead of 'skylake_avx512' Or use a different m4 - say from /usr/bin - if you have it there.
