: This usually means the compiler is not correctly selected in your IDE. Check Project Properties > Conf > XC Compiler to ensure the path is set.
Microchip divides its hardware support across three separate compilers. Choose the one that matches your hardware:
Go to: Microchip XC Compilers
For all 8-bit microcontrollers (PIC10, PIC12, PIC16, PIC18, and AVR MCUs). MPLAB XC16: For 16-bit devices (PIC24 MCUs and dsPIC DSCs).
On Windows, the most reliable way to get X11 headers and libraries is through the MSYS2 environment.
If you are developing firmware for Microchip PIC microcontrollers, you have likely encountered the line #include . This header file is the gateway to programming PIC devices using the modern MPLAB XC compiler suite.
