I don't think it's possible to do without the *.obj files, sorry.

Hello Ansgar,

your setup sounds like a EU R&D project where each party provides
its proprietary component model and you are the poor guy who has
to compile the integrated system model. Here's the recipe:

(1) Each party has to implement its component model as reentrant
C/C++ functions and compile them into a static object library.
(2) Change the MEX-file S-function to call the C/C++ functions.
(3) Write a TLC wrapper calling the same C/C++ function.
(4) Generate the Rsim target and tell RTW that it has to link
against the static object libraries (see rtwmakecfg).

That way it works (done that), even if using different compilers.
Some details have to be considered (ssSetInputPortRequiredContiguous,
mdlRTW, ...) but its not too hard to do it right.
