[petsc-users] Debugger won't start

[Karthikeyan Chockalingam - STFC UKRI]

Thank you for your response. I am trying to debug in parallel and the used the flags in the link you sent me

mpirun -np 2 ./ex45 -start_in_debugger -debug_terminal "screen -X -S debug screen"

but the problem still persists. Now, I get a different message

No screen session found.

    If you are debugging a program with one MPI process, you can just do "-start_in_debugger noxterm". Otherwise, have a look at https://petsc.org/release/docs/manualpages/Sys/PetscSetDebugTerminal.html
