C++ or C with S-Function Builer from Simulink?

Hello everyone,

I went through the documentation for the S-Function Builder from Mathworks, but I do not know if it is possible use c++ with S-Function Builder or just C.

I did some test and I wrote the same code for a C and for a C++ using a S-Function Builer. For the one in C I did not get errors, but for the one in C++ I got linking errors.

In the Mathworks documentation, the S-Function Builder is inside the topic "Writing S-Functions in C", but not inside "Creating C++ S-Functions"; that is why my question.

Any hint or any help would be really appreciated.

Thank you very much for your help
