They are: > Option left: name:-online_mode value: 1 > Option left: name:-pc_factor_mat_solver_package value: superlu > I think this is all working as intended, since if you look at run.sh for reduced_basis_ex7, you can see that we run all four combinations of "type"/"package" and "mumps"/superlu" from the script, relying on the logic within the example itself to skip those cases which don't apply. If you want to test whether it's working you can run the example manually with the different cases and inspect the output of each one rather than running the full "make check". The examples must be run from the build directory, so for example to test mumps with PETSC >= 3.9 (assuming $LIBMESH_SRC/build is the location of your build directory): cd $LIBMESH_SRC/build/examples/reduced_basis/reduced_basis_ex7 ./example-opt -online_mode 0 -ksp_type preonly -pc_type lu -pc_factor_mat_solver_type mumps Finally, there is one last check you can do, which is to look at (again, from the build directory) the include/libmesh_config.h file and inspect the values of the LIBMESH_PETSC_HAVE_MUMPS LIBMESH_PETSC_HAVE_SUPERLU_DIST preprocessor defines. > ,*************************************************************** > ,* Done Running Example reduced_basis_ex7: > ,* ./example-opt -online_mode 1 -pc_factor_mat_solver_package > superlu > ,*************************************************************** > #+end_EXAMPLE > > I get a similar message above with mumps.
