.so file of FMI for model exchange problem

[Mongi]

When trying to load the .so file of an FMU, dlopen returns (nil).
dlerror returns : "undifined symobl : KINSetUserData"

Do you have "libsundials-kinsol1 - KINSOL solver (SUNDIALS library)" installed on your system?

[Mongi]

I have installed sundials 2.4 and sundials 2.5 (./configure, make then make install).
At link process, libsundials_kinsol.a is found.

Is libsundials-kinsol1 different from libsundials_kinsol? I guess it is installed using apt-get. In which debian distribution can I find it?

[Martin Sjölund]

I have:
$ nm /usr/lib/libsundials_kinsol.a | grep KINSetUs
00000000000001a0 T KINSetUserData

So if you linked in libsundials_kinsol.a, you should be fine. I use Ubuntu 12.04.

[Mongi]

For me $ nm /usr/lib/libsundials_kinsol.a | grep KINSetUs does not return anything.
How can I get the right version of libsundials_kinsol.a ?

[Martin Sjölund]

The file was in: pool/universe/s/sundials/libsundials-serial-dev_2.4.0-5_amd64.deb

I got the same problem when trying to execute the "simulate" command in OMShell :

The problem was solved by linking with 2.4 Sundials libs version (libsundials_kinsol.a) I found in usr/local/libs

Thank you for your help Martin
