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/p… 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

Help needed with failing PPC build: cannot find MPI with openmpi

Hello, A tool I am trying to package is failing only on PPC somehow: https://bugzilla.redhat.com/show_bug.cgi?id=1731487 > make[2]: Leaving directory '/builddir/build/BUILD/MUSIC-a78a8e2c90b07274db94265db75c320dbb01f9fb/MUSIC-a78a8e2c90b07274db94265db75c320dbb01f9fb-openmpi/src' > BUILDSTDERR: error.cc: In function 'void MUSIC::error()': > BUILDSTDERR: error.cc:36:5: error: 'MPI' has not been declared > BUILDSTDERR: 36 | MPI::COMM_WORLD.Abort (1); > BUILDSTDERR: | ^~~ > BUILDSTDERR: error.cc: In function 'int MUSIC::getRank()': > BUILDSTDERR: error.cc:70:9: error: 'MPI' has not been declared > BUILDSTDERR: 70 | if (MPI::Is_initialized ()) > BUILDSTDERR: | ^~~ > BUILDSTDERR: error.cc:71:14: error: 'MPI' has not been declared > BUILDSTDERR: 71 | return MPI::COMM_WORLD.Get_rank (); > BUILDSTDERR: | ^~~ > BUILDSTDERR: make[2]: *** [Makefile:739: libmusic_la-error.lo] Error 1 On all other arches, it builds just fine, so there's something different with the openmpi package on ppc here. Any ideas? -- Thanks, Regards, Ankur Sinha "FranciscoD" (He / Him / His) | https://fedoraproject.org/wiki/User:Ankursinha Time zone: Europe/London
