You will need MATLAB Coder to perform the conversion. If it is already installed, you can use MATLAB coder app under Apps tab in MATLAB. It will guide you through steps to generate C or C++ code.

Yes, mex files are platform specific. I think that the generated C code should work on other platforms too, but I am not entirely sure.
