Hello,

Does anyone ever succeeded to compile freefem using spack (without mpi and petsc first)? I get errors during compilation so i modified the package.py script and it appears it lacks dependencies : mpi, hdf5, lapack, superlu… the script doesn’t use spack package dependencies.

Best regards.

I finally succeeded to compile with petsc but with some modifications.
