The issue you're encountering seems to be related to the code generation process not properly overwriting or managing previously generated files. This can be due to a variety of reasons, including but not limited to, file permissions, Simulink configuration settings, or issues within specific setup.
As a workaround, before building your project for the second time, use a pre-build callback to automate this. In Simulink, you can configure a pre-build callback as follows:
- In the Simulink® Toolstrip, on the Modeling tab, in the Design gallery, click Property Inspector.
- With no selection at the top level of your model or referenced model, on the Properties tab, in the Callbacks section, select the callback - InitFcn and update the model before each build.
- Here’s the callback code you can use:
try
rmdir('RollAxisAutopilot_ert_rtw', 's');
rmdir('slprj', 's');
catch Me
disp(Me.message);
end
where RollAxisAutopilot was the model name I used- you can replace it with yours.
You can use a function to clean the build folder, albeit you'd have to run it manually every time unless it's integrated into the model’s callbacks for automatic execution.
