Hello Everyone, I am trying to compile the most recent version of FreeFEM from the develop branch. The compilation seems successful, but when I try to run the codes, I get random error messages, probably related to PETSc. E.g., [0]PETSC ERROR: --------------------- Error Message ------------------…

What if you let PETSc compile MPICH? Are you sure there is no other instances of PETSc.so (the FreeFEM plugin) somewhere else on the machine? Where does the error happen (inside FreeFEM sources or on a directory somewhere else)?

Thanks for the prompt reply. Compiling MPICH with PETSc seems to have resolved the issue.
