Hi Sébastien, I've updated the git branch for this feature: https://salsa.debian.org/science-team/openblas/commits/lumin It can be built against the git master version of src:lapack (i.e. 3.8.0-4 + 1 commit that fixes installation path). Problems pointed out in the previous round of review have been fixed already. Building libjulia-openblas has been postponed. I'm thinking of a better choice.
