Hello,

I am getting this error when trying to build project in configuration desk (Dspace). When i build the model thorugh simulink, the build process does not give error, however it gives this error when building via configuration desk.

Hi,

I understand that you are getting error when building the model via configuration desk, but not through Simulink.

The error message says that there is an issue with generating code for the ‘testing_steering_4’ model in Configuration Desk. The specific error is related to obtaining sizes from the MEX S-function 'casadi_fun' in the 'testing_steering_4/S-Function'.

Few of the possible workarounds could be:

Ensure that all relevant files and dependencies are included and available within the Configuration Desk project. Check to see that the 'casadi_fun' S-function, as well as any other needed files, are available and appropriately referenced.
Check that the necessary MATLAB/Simulink toolboxes and libraries are installed, as they may be required for the code generation process. Make sure that the versions of MATLAB, Simulink, and Configuration Desk are compatible.
Check Configuration Desk for any specific build settings or configurations that need to be changed for the 'testing_steering_4' model. Examine the model's configuration settings to ensure they are set appropriately.
