Compile Errors occured when simulink models including 'cmex' by SIT

Question

I am trying to compile a simulink model to DLL with following softwares and hardwares.
Software:
LabVIEW 8.0.1
LabVIEW Realtime 8.0.1
Simulation Interface Toolkit 3.0
MATLAB R13
Visual C++ 6.0 Service Pack 4
Target Hardware:
PXI-1042RTPXI-8196
PXI-6289
When I tried to compile a model including 'cmex' function on Simulink to DLL, compile error about Visual C++ occured. Does SIT support the model including 'cmex' functions?
When I removed the function 'cmex', compiling is working correctly.
To import original model which is written by C or other language, I strongly want to use 'cmex' functions. To avoid the compile error, if you have any ideas, please let me know.
Thanks,
Tsugo

Hello Tsugo,
I believe that it is possible to compile a DLL for SIT from a model that contains a cmex function.
To tell whether the issue is caused by SIT or not, you can try changing the RTW target file from nidll.tlc to grt.tlc (in the model's Simulation Parameters dialog, look in the Real-Time Workshop tab), and see whether the compile error still happens. If the compiler error occurs with grt.tlc, then please refer to the documentation provided by The MathWorks Inc. on how to get your cmex functions to work in Real-Time Workshop®.
If the compiler error does not occur with grt.tlc, then please post the whole text of the compiler error.
Thanks!
