Package: octave Version: 9.2.0-3 Severity: normal sundials 7 is now available in experimental
In principle octave 9.2 is already patched to support sundials 7, and indeed configure does find ida/ida.h, SUNLinSol_Dense, SUNSparseMatrix_Reallocate etc. But it misses nvector_serial.h for some reason, and consequently loses support for ode15i and ode15s checking for klu.h... yes checking for klu_solve in -lklu ... yes checking for UMFPACK separate complex matrix and rhs split... yes checking for nvector_serial.h... no checking for nvector/nvector_serial.h... no configure: WARNING: SUNDIALS NVECTOR serial library not found. The solvers ode15i and ode15s will be disabled. Not quite sure why it's missing nvector/nvector_serial.h. It's still provided by libsundials-dev 7.1.1+dfsg1-1exp1 There is one point to keep in mind for sundials 7. MPI support is now moved into the core library because of sunmpicomm, introduced in https://github.com/LLNL/sundials/pull/370 So a standard build might fail with "sundials_types.h:57:10: fatal error: mpi.h: No such file or directory" which can be worked around by setting CC=mpicc But the nvector error message doesn't refer to mpi, so not certain if that's why configuration missed nvector_serial.h
