Can't access the solvers

Certhas commented 7 years ago

I tried installing this package but unfortunately I can't seem to get it (or the assimulo package for that matter) to work. When I try to load the library I get the following error:

In [1]: import ctypes

In [2]: testlib = ctypes.CDLL("libsundials_ida.so")
---------------------------------------------------------------------------

Potentially related, assimulo doesn't work: https://github.com/conda-forge/assimulo-feedstock/issues/4

Not sure what's going on there, but dscal is a BLAS function. I haven't used assimulo myself but I've been using conda-forge/sundials under linux successfully, see e.g. this CI log: https://travis-ci.org/chemreac/chemreac/builds/199563004

they do not link lapack in their libs: b59eabc, see #8, you can see it if you "ldd -r ...libsundials_arkode.so"

jschueller commented 7 years ago

should be fixed by #8

conda-forge / sundials-feedstock

Can't access the solvers #7
