Unable to create mex function for simulink model

Hi,

Whenever I'm tryng to run (Ctrl+D) my simulink model it is giving the error:

Making simulation target vce_driveline_sfun. 'nmake' is not recognized as an internal or external command, operable program or batch file.

Component:Make | Category:Make error

Unable to create mex function 'vce_driveline_sfun.lib' required for simulation.

Component:Simulink | Category:Model error

I found a workaround for this issue:

"try this solution :- setting requires in Configuration Parameters > Simulation Target > Adavanced Parameters > Enable Genetared typedefs for imported bus and enumeration type."

By doing the above, I'm able to Run the model, but not able to save the model with this setting.

So immediatley after when I'm trying to generate code for the model it is returning error:

>> GenCode(options,{'DtCtrl'});

### Build procedure for DtCtrl aborted due to an error.

------------------------

I know its related to some compiler issue.

Is there a way to fix it ?

Thanks!

Hi Joydeep,

The error message you see when you run the model could be due to the system PATH environment variables in MATLAB. I suggest you check if the Visual Studio path is set properly. A model would be helpful for further debugging, if the issue is still persistent.
