[Octave-bug-tracker] [bug #52475] ode15 is not compatible with SUNDIALS >= 3.0.0

[John W. Eaton]

Follow-up Comment #72, bug #52475 (project octave):

Carlo:  I did have klu installed and the header sunlinsol/sunlinsol_klu.h was
also present but not detected by configure.  After looking more closely at the
configuration problems, I found that it wasn't finding klu.h because on my
system it is installed in /usr/include/suitesparse/klu.h but the sundials
header is still only including <klu.h>.  After adding
-I/usr/include/suitesparse to CPPFLAGS it builds with your patches using my
self-compiled copy of sundials 4.1.0.  I configured that with


cmake \
  -DKLU_INCLUDE_DIR=/usr/include/suitesparse \
  -DKLU_LIBRARY_DIR=/usr/lib/x86_64-linux-gnu \
  -DKLU_ENABLE=on \
  -DCMAKE_INSTALL_PREFIX=/usr/local/sundials/4.1.0


If I try to use the version installed on my system (3.1.2 on Debian), I see
the following error:


/home/jwe/src/octave/libinterp/dldfcn/__ode15__.cc: In member function 'void
octave::IDA::jacsparse_impl(realtype, realtype, _generic_N_Vector*&,

Can we detect that Sundials is installed to use 32-bit integer indexing and
adapt to that the same as we do for BLAS, LAPACK, and some other libraries?

In any case, I think it would be fine to apply these changes now.
