I pushed a commit to disable the openmp support on F30+ for now as it's causing the FTBFS issue when building with gcc 9: https://src.fedoraproject.org/rpms/darktable/c/5a91db55725ec4f164ed7abcf60f95f9534a8dec?branch=master It could use some more investigation and an upstream bug report, but this should for now at least fix the broken darktable deps due to the exiv2 0.27 soname bump.
