Hi Matthais,
Just for your clarification, MATLAB actually uses both the compilers i.e “gcc” and “g++” under the hood for compiling the “.c” files and “.cpp” files respectively. After the object code is created, “gcc” is again used to build the MEX file. You can peer under the hood to see the execution of the “mex” function by using the “-v” flag. Here is a useful documentation that explains the whole process of creating, compiling, and linking MEX files in great detail:
Also, Yes, it is possible to generate the “.obj” file individually with the corresponding compilers and then link them to a MEX-file of your choosing in MATLAB. Please refer to the below MEX command for linking the two object files manually:
mex -output your_mexfile your_c_code.o your_cpp_code.o
Here is the documentation for the “mex” function for some additional information on how to build such files:
Hope it helps!
