Hello all. I've asked this question to Satish personally last week at the conference, but I'm stuck so any help would be appreciated. For some reason not worth explaining, I need to activate -info after PetscInitialize() has been already called. I'm trying something like this: PetscOptionsSetValue(NULL, "-info", NULL); PetscInfoSetFromOptions(NULL); The second call fails with [0]PETSC ERROR: --------------------- Error Message -------------------------------------------------------------- [0]PETSC ERROR: Object is in wrong state [0]PETSC ERROR: PetscInfoSetClasses() cannot be called after PetscInfoGetClass() or PetscInfoProcessClass() [0]PETSC ERROR: See https://petsc.org/release/faq/ for trouble shooting.

I also tried using a local PetscOptions object but the result is the same. Any ideas to avoid that wrong state error? Thanks -- jeremy
