In mucking about trying to solve another issue, I stumbled on this setting in my recent 13.1 (from DVD, subsequently updated)install
~ echo $LD_LIBRARY_PATH /usr/lib64/mpi/gcc/openmpi/lib64
My general understanding is that LD_LIBRARY_PATH can be a great debugging tool but in general should not be used as a default library path.
I don’t (knowingly) use openMPI.
I note that it is also installed on my 12.3 system, but no LD_LIBRARY_PATH is set there.
Is there any way to determine if this is really desired/required vs. an unintentional leftover?
