Hi Chong-He,

The error messages you are encountering indicate that the build process for your Simulink model “Lab1_Inverter” is failing due to issues with custom code paths. Specifically, it seems that the path specified for custom include directories does not exist, which is causing the build to abort.

Here are some steps you can follow to resolve this issue:

1.Verify Path Existence: Check the path “D:\Desktop\GW\PEK-550\2022b\include” to ensure it exists on your system. If it doesn't, you need to create the directory or adjust the path to point to the correct location.

2.Update Custom Code Settings:

• Open your Simulink model.
• Go to Model Configuration using “Ctrl + E” or using the menu Simulation > Model Configuration Parameters.
• Navigate to Code Generation > Custom Code.
• Check the Include directories field and update the path to a valid directory that contains your custom header files.
• Add the necessary headers to "Include headers" and source files.

By ensuring that all paths specified in the custom code settings are correct and accessible, you should be able to resolve the build error and successfully generate code for your model.

You can also consider moving your custom code to the same directory as your model and try building again after specifying the custom headers and source files.

For more information about code customization with Simulink Coder, you can refer the following documentation:
