I am trying to compile and deploy from my Win7 64bit laptop to a Raspberry Pi 3 Model B a Simulink Phase Space model having inside a Sfunction to include in the model a c++ code that my university provided me. I am sure to be connected to the Pi (I get the mypi variable and establish the connection), indeed I am able to compile and deploy to the Pi simple Simulink models (for instance to blink the Pi's green led).
The issue is when I try to compile the full Phase Space model because the c++ function needs some external libraries (.lib) to run. I am able to compile the .mexw64 file from Matlab using SDK compiler and providing it with the libraries. But when I compile and deploy the full Phase Space model from Simulink (''Deploy to hardware'' button) using the GNU GCC Raspberry Pi compiler I get an error saying the .lib extension is not recognized. So my question is how to compile Sfunction requiring external libraries .lib?
