svsolver Ubuntu 20.04 compatibility

[Peter Patalano]

I recently upgraded the OS on one of my machines to Ubuntu 20.04. I am now having in issue with getting svsolver to run as it relies on libgfortran3 but it appears that this is not compatible with 20.04.

I am wondering if anyone has run into this problem or a similar one...?

In the meantime, I will try to set up an environment in Anaconda to try and solve this issue.

Additionally, I notice that if I try to run the solver from the SV application I get the following error

Code: Select all

Run job failed with: Check MPI

The application is directed to use /usr/bin/mpiexec so I am not sure where the issue is here. I will continue to try and debug this.

I corrected the libgfortran issue by using a copy of libgfortran.so.3 that came standalone with another program and copying it to /usr/lib/libgfortran.so.3

So, I can now run the solver from the command line but not the SV gui. This is good enough for me, but might be helpful to figure out the mpi issue with the GUI.

Hi Peter,

Thanks for identifying these problems!

The svSolver installer includes a lib directory that has libraries needed for svsolver to run. It looks like we will need to add a libgfortran.so.3 library to the installer.

I'll have a look at the mpi problem. SV tries to identify the mpi implementation, checks that it is MPICH, maybe this is not working on Ubuntu 20.

Cheers,
Dave
