Hello,
I did a search of this error message and didnt find anything so hoping you guys can help. I did find a few mentions on google but they were for another application and mentioned a wrong /lib folder in the config. I have a Professor who is trying to install SU2 on our IBM Spectrum Scale HPC. During install the Professor has set LD_LIBRARY_PATH="/opt/ibm/platform_mpi/lib" mpirun path is “/opt/ibm/platform_mpi/bin/mpirun“. mpicc path as "/usr/mpi/gcc/openmpi-2.1.2a1/bin/mpicc" and mpicxx path as "/usr/mpi/gcc/openmpi-2.1.2a1/bin/mpicxx". We also tried mpirun path as “/opt/ibm/platform_mpi/bin/mpirun“. mpicc path as “/opt/ibm/platform_mpi/bin/mpicc“ mpicxx path as “/opt/ibm/platform_mpi/bin/mpicxx“ But Still get this error. SU2_CFD: error while loading shared libraries: libmpi.so.20: cannot open shared object file: No such file or directory thanks for any information you can give me. |

Are you building the code from source or using the precompiled binaries?

Can you post the output during compilation just to make sure the build system picked up MPI (and which version).
Also LD_LIBRARY_PATH needs to be set when you run the code, not just when compiling. |

Thanks for the reply. I believe the problem is we need an update. Working with vendor on this.
Thank you. |
