SUNDIALS_BLAS_LAPACK not present in sundials 6

[martinjrobins]

I'm trying to use the latest version of scikits.odes that uses sundials v6. I'm having trouble getting scikits.odes to recognise the lapack dense solver, and am getting the following error:

======================================================================
ERROR: test_model_solver_ode_jacobian_python (test_solvers.test_scikits_solvers.TestScikitsSolvers)

It looks like scikits.odes is looking for the SUNDIALS_BLAS_LAPACK define in sundials_config.h, as per this line

odes/setup_build.py

Line 107 in dc2dccc

"SUNDIALS_BLAS_LAPACK", headers=[SUNDIALS_CONFIG_H],

but I don't think sundials v6 defines this, even if the sundials lapack solvers are compiled. Instead in my sundials_config.h I have:

#define SUNDIALS_SUNLINSOL_LAPACKBAND 1
#define SUNDIALS_SUNLINSOL_LAPACKDENSE 1

Hello,

I got same issues using the latest version of scikits.odes. Did you manage to fix it?

Thanks
