Hi, I guess this is caused by the ouptut of "mpicc --show-me:link"
On older OpenMPI version this is: gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -L/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi On OpenMPI 5.0.5 it includes an rpath: gcc -I/usr/lib/x86_64-linux-gnu/openmpi/include -I/usr/lib/x86_64-linux-gnu/openmpi/include/openmpi -L/usr/lib/x86_64-linux-gnu/openmpi/lib -Wl,-rpath -Wl,/usr/lib/x86_64-linux-gnu/openmpi/lib -lmpi Best, Markus
