In the linking step I am getting this error:

c:\program files (x86)\matlab\r2012b\extern\include\matrix.h(301) : error C2371: 'mxArray' : redefinition; different basic types c:\program files (x86)\matlab\r2012b\simulink\include\simstruc.h(474) : see declaration of 'mxArray'

I am using VS2010 C++ compiler. The two header files seem are matlab and simulink includes, so I'm not sure why they don't play nice together.

I have also the same problem. I have no problem when I compile my sfunction with visual studio 2010 C++ compiler. But I have the error when I try to generate code from my model whichn includes this S-function. Any idea?

I find solution, it happens because "simstruct.h" (the C s-function hearder) does not include the same headers when compiling in mexw32 (for simulation) or when compiling a model with simulink coder. It was explained in the link bellow:

http://www.mathworks.fr/fr/help/simulink/sfg/templates-for-c-s-functions.html

My problem comes from functions include in "matrix.h", (which is not include when compiling with simulink coder), so the solution was to use only functions include both in matrix.h and rt_matrx.h
