MATLAB Simulink CallMakeHook Error

Hi there,

I am using MATLAB r2007a with Code Composer Studio v3.1. When I generate code form simulink model, the following error appears:

Error building Real-Time Workshop target for block diagram 'model2'. MATLAB error message:
Error using ==> callMakeHook.p>callMakeHook at 47
The call to ccslink_grt_make_rtw_hook, during the entry hook generated the following error:
    Error using ==> i_entryHookpoint at 52
Error while creating the link for IDE.

The build process will terminate as a result.

Please someone help me to resolve this issue.

Thanks

Best regards
