[petsc-users] Start logging with -info after PetscInitialize()

[Jeremy Theler (External)]

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: #2 PetscInfoSetFromOptions() at /home/jtheler/libs/petsc-3.19.2/src/sys/info/verboseinfo.c:407

But if I ignore the non-zero return value and I allow my program to continue, the required logging is enabled.
I also tried using a local PetscOptions object but the result is the same.

Any ideas to avoid that wrong state error?

Thanks
