Source: deal.ii Version: 9.5.1-3 Severity: important sundials 7 (in experimental) introduced enough API changes that probably break deal.ii 9.5. deal.ii 9.6 has already been updated to support sundials 7, so please update to the latest upstream release.
Note that sundials 7 moves MPI support into the core library, due to sunmpicomm introduced in https://github.com/LLNL/sundials/pull/370 So a standard deal.ii build might fail with "sundials_types.h:57:10: fatal error: mpi.h: No such file or directory" If this is the case for deal.ii and it's not already managing it's own MPI include directories, then the issue can be worked around by configuring the C++ compiler to mpicxx for the deal.ii build. We want to upload sundials 7 soon (transition #1082552), at which point this bug would likely become severity: serious
