error while loading shared libraries: libmpi_cxx.so.20: cannot open shared object file: No such file or directory
I am sure libopenmpi-dev has been install already.
Please can anyone suggest what’s wrong?
I followed the guideline for Ubuntu installation, and installed
FreeFEM_4.9_Ubuntu_withPETSc_amd64.deb
BTW, serial FreeFem++ command works well.
