Source: combblas Followup-For: Bug #940664 There's an issue raised in the mpicc bug report #919308 for scotch which needs to be addressed before we can take action.
pkg-config is not a complete replacement for mpicc, or at least there is a discrepancy in the flags generated: $ mpicc -showme:link -pthread -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi $ pkg-config --libs mpi-c -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi Without or without -pthread? mpicc seems to think it's important to link with -pthread.
