Hello,
If I'm right, Code_Aster 17.5.4 requires codeaster-prerequisites-20251026-oss.tar.gz, and this tarball contains the tarballs of the prerequisites. Among them, there is petsc-3rd-v3.24.0.tar.gz, with the third parties needed with PETSc, and it contains pkg-trilinos-ml-v13.2.0.tar.gz.
But Trilinos-ML is deprecated: see https://github.com/trilinos/ML .
Do we really need it?
