you need the additional option -with-mumps-serial=1 For example - check config/examples/arch-ci-linux-cuda-uni-pkgs.py Satish On Fri, 11 Apr 2025, salvador wrote:Dear PETSc team, I'm trying to compile PETSc with *MUMPS* in *serial mode* (without MPI), and I’ve encountered an issue during the |./configure| step.

Any guidance would be appreciated. Best regards, /Salvador /
