I'm a newbie in MATLAB. I am trying to build my modell with an example for S-Function from the matlab help. This is the sfun_counter_cpp.cpp. The source code is available in "matlabroot/simulink/src/sfun_counter_cpp.cpp" or on http://www-rohan.sdsu.edu/doc/matlab/toolbox/simulink/sfg/sfun_c++2.html.
First I build C++ S-function with the "mex" command as described here: http://www.mathworks.de/de/help/simulink/sfg/building-c-s-functions.html. The build is successful and the sfun_counter_cpp.mexw32 is created. After that I create an S-Function block that provides access to sfun_counter_cpp from my block diagram, click "Incremental build" and get an error message "OPUS MAKE: Don't know how to make 'sfun_counter_cpp.cppm50'. Stop."

The problem is solved. I set
USER_BUILD_CPP_APPL = ON
and
USER_SRCS =
USER_SRCS = sfun_counter_cpp.cpp produces an error
