Looking at config.log, I confirm that the problem comes from mpi.h not being found. However I’m quite reluctant to compiling Octave with a MPI compiler wrapper, as you suggest. This is not the recommended way of compiling Octave, and I am not really willing to deal with the issues that could arise because of that change. If I understand correctly what happened in sundials upstream, an alternative could be to provide distinct Debian packages of sundials without MPI support. But of course that means more work for you. -- ⢀⣴⠾⠻⢶⣦⠀ Sébastien Villemot ⣾⠁⢠⠒⠀⣿⡁ Debian Developer ⢿⡄⠘⠷⠚⠋⠀ https://sebastien.villemot.name ⠈⠳⣄⠀⠀⠀⠀ https://www.debian.org
