Thanks Orion, Jerry. I'll keep an eye out for the fix and then retry the build. Out of curiosity: shouldn't this have affected all tools using OpenMPI C++ bindings? NEST, for example built fine even on ppc: https://koji.fedoraproject.org/koji/buildinfo?buildID=1362315 Build log: https://kojipkgs.fedoraproject.org//packages/nest/2.18.0/5.fc32/data/logs/ppc64le/build.log I see that it found mpicxx, but not headers etc. However, that didn't cause the build to fail (line #2439). -- Thanks, Regards, Ankur Sinha "FranciscoD" (He / Him / His) | https://fedoraproject.org/wiki/User:Ankursinha Time zone: Europe/London
