How to generate C++ code from model with S-Functions using ert_shrlib target ?

Hi!

I designed a model with some S-functions (on Matlab 2016b) and I convert it to C or C++ using ert_shrlib but I always get errors.

But when when i compile in my C/C++ IDE, this error appears : "Must define one of RT, NRT, MATLAB_MEX_FLIE, SL_INTERNAL, or FIPXT_SHARED_MODULE" in simustruc.h. I don't really know if it's linked but is it possible to generate C/C++ code from an S-Function?

If yes, How ?

Thanks!
