Dear deal.ii community, I am using deali.ii with PETSc and Trilinos. However, when I am using the PETSc PreconditionILU I get an error that suggests that a solver package is missing (with Trilinos it works). Petsc's PreconditionAMG works fine (although not very efficiently for my problem). Do I need to do any special configuration steps for PETSC? I followed the instructions that are documented on the deal.ii pages on "how to configure Petsc". https://www.dealii.org/current/external-libs/petsc.html
