[Octave-bug-tracker] [bug #59248] configure is still testing for a function (IDADense) which does not exists anymore in sundials

[Markus Mützel]

Update of bug #59248 (project octave):

                  Status:          Ready For Test => In Progress

Follow-up Comment #3:

That turns out to be more complicated than what I hoped it would be.
The configure output contains:

checking for SUNDenseLinearSolver... yes
checking whether SUNDIALS API provides the necessary functions... yes


Yet compilation fails with:

../src/libinterp/dldfcn/__ode15__.cc: In function ‘_generic_SUNLinearSolver*

../src/libinterp/dldfcn/__ode15__.cc:103:12: error: ‘SUNDenseLinearSolver’

That's probably because I removed the test
`AC_CHECK_HEADERS([sunlinsol/sunlinsol_dense.h])`. I am currently trying to
find the best place to add that back in.
