How are you compiling this file, is this with the Visual Studio IDE or with mex? If with mex, can you show the full mex command that you are using?

Dekun: It looks like Luen is simply updating a model containing Stateflow charts and/or MATLAB Function blocks.

Leun: I would recommend contacting MathWorks Tech Support if you are unable to get help on the forum.

Hi all, I am trying to compile the simulink model and got these error message.

This is interesting because the linking command looks right, yet it is complaining about unresolved symbols. Can you locate this file and see if it is present: C:\MatLab\R2010bSP1\extern\lib\win64\microsoft\libmx.lib

This lib files contains symbols for mxGetString, mxIsChar, etc, but these symbols are currently reported unresolved from your error.

The other possibility I can think of is if you switch between 32-bit and 64-bit MATLAB of the same release and did not do "mex -setup" every time you switch. The MEX option file (it configures the environment to compile the stateflow chart) is in the preference directory shared by both 32-bit and 64-bit MATLAB, yet the content is slightly different for 32-bit and 64-bit. So you if did a "mex -setup" on a 32-bit MATLAB and then switch to 64-bit, MEX will get inconsistent. This will also be an issue if you have two of the same release of MATLAB installed at different locations.

I am also trying to compile the code in Visual Studio 2010. and got the same error like

1>simulink.obj : error LNK2019: unresolved external symbol _mdlTerminate referenced in function _mexFunction 1>simulink.obj : error LNK2019: unresolved external symbol _mdlOutputs referenced in function _mexFunction 1>simulink.obj : error LNK2019: unresolved external symbol _mdlStart referenced in function _mexFunction 1>simulink.obj : error LNK2019: unresolved external symbol _mdlInitializeSampleTimes referenced in function _mexFunction

Please give an idea for this.
