I unzipped the tarball for 5.10.1-MPI, ran the apt-get install commands in the 1st post (with “qt5-default” removed from the first command), and then ran ./paraview .
I also built it from source using the instructions at:
https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md
This showed debug messages but also failed.
Finally, I built 5.10.1-MPI from source with the MPI option turned OFF. This runs successfully.
So, it is definitely a problem with MPI on my system. I want to continue to try to get the MPI version of paraview working.
My device architecture is x86_64.
