I can make changes according to your needs. Just let me know if you want to add or modify anything.
If the IDE cannot locate the file, the compiler installation may be corrupt. Uninstall the XC compiler and reinstall the latest version.

sudo yum install libX11-devel
Run the downloaded installer on your machine. During the installation wizard:
If you need the header file named "xc.h" (commonly used for Microchip XC compilers for PIC microcontrollers), download it by installing the appropriate Microchip XC compiler package for your target device: xc.h library download
You do not download the file manually. You must install the Microchip development tools.
The library is not a standalone file you download individually; it is a critical component of the MPLAB XC Compilers . To obtain this file, you must download and install the appropriate XC compiler (XC8, XC16, or XC32) for your Microchip microcontroller. Why You Need xc.h
The IDE handles this by allowing you to select your target MCU (e.g., PIC18F45K22) in the project settings, which allows xc.h to select the right definitions. I can make changes according to your needs
In the dropdown on the right, explicitly select the version of XC8/XC16/XC32 you installed. Click Apply and then OK . Clean and rebuild your project. Fix 3: Check C Standard Compliance
For 32-bit microcontrollers (PIC32MX, PIC32MZ, SAM devices). Step 2: Download from the Official Source
Navigate to the official download page.
Would you like me to add any of the following:
Right-click your project, go to Properties , and ensure the correct compiler (e.g., XC8) is selected. Add Include Paths:
