Dear Paul, > I would like to eventually package the Lethe CFD library
Nice! Trilinos has many bells and whistles. I imagine that there will be some significant effort required to package it. One option would be to subdivide the library and initially package only the elements you need for Lethe. See the Debian approach to packaging Trilinos for example [1]. If Lethe does not use PETSc there would be no risk of conflict. The choice between including the new Trilinos (sub)package as a dependency of dealii and dealii-openmpi or creating new dealii-trilinos and dealii-trilinos-openmpi packages would be marginal. How many models need to use PETSc and Trilinos at the same time? > This assumes people won't mind having to build Trilinos as a > dependency for dealii even if they don't need it. The model run times are usually very much longer than the library build times. I expect this would be true for Trilinos and Lethe too. Best regards, Paul.
