That seems to be correct according to both the build logs and some local testing. > While I don't think that there is an big problem with this, we should > probably still recompile opm-grid to have both modules use > the same defines. > > The define is uses in a header and source file, but the API should be > unchanged.

Emilio, while not strictly required for the scotch transition (the old scotch packages have been removed from testing) the following will fix the above issue: wb nmu 3 opm-grid_2025.10+ds-1 . amd64 arm64 ppc64el riscv64 loong64 . -m 'Rebuild against scotch 7.0.10-7' wb nmu 1 opm-simulators_2025.10+ds-4 . amd64 arm64 ppc64el riscv64 loong64 . -m 'Rebuild against scotch 7.0.10-7' wb dw opm-simulators_2025.10+ds-4 . amd64 arm64 ppc64el riscv64 loong64 . -m 'libopm-grid-dev (>= 2025.10+ds-1+b3)' > Best, > > Markus cu Adrian
