Set the Include Directory Path for the MPLAB® XC32 Compiler

Last modified by Microchip on 2023/11/09 09:12

The Include Directory paths are used by the C compiler to find files referenced through #include directives. This is the preferred method of referencing include files that are not at the root of your project directory, as opposed to using relative paths in code: #include "subdirectory/filename.h").

Open the project properties window

Either right-click on the top node of the project in the Project window and select Properties from the pop-up window, or from the File menu, select Project Properties (ProjectName).
