Unable to export Simulink model to FMU (lcclnk64 not recognized)

5 views (last 30 days)
I have been unable to export my Simulink Model to FMU. I noticed the lcclnk64 does not exist in the designated folder. I have also been searching for solution for this but there seems to be none. I also have raised service request but did not get any reply from MathWorks Technical support.
The ouput of exportToFMU2CS is below. I am hoping some people have a workaround for this issue. I appreciate any help.
success = exportToFMU2CS('FRx_sl','CreateModelAfterGeneratingFMU','on')
Setting System Target to FMU Co-Simulation for model 'FRx_sl'.
Setting Hardware Implementation > Device Type to 'MATLAB Host' for model 'FRx_sl'.
### 'GenerateComments' is disabled for Co-Simulation Standalone FMU Export.

Hi Cynthia Wang,
I understand that you are unable to export Simulink model to FMU because of the error ‘lcclnk64’ is not recognized.
Exporting a Simulink model to Functional Mockup Unit requires C code generation, which will require a supported C compiler. In this case, the LCC C compiler is not a supported C compiler.
To resolve this issue, the C compiler must be changed from LCC to a supported C compiler. A list of supported C compiler is given in the documentation link:
The recommended free C compiler for MathWorks products is Min GW which can be downloaded from the above mentioned documentation link.
Once downloaded, the default C compiler needs to be set to Min GW following the below documentation link:
Hope this information helps you.
