Interrupt Service Routines should be as lean as possible. Avoid complex math or function calls inside an ISR to prevent latency issues. Troubleshooting Common Compiler Errors
The XC compilers are strict. Ensure you haven't missed a semicolon or used a reserved keyword for a variable name. Conclusion mplab x compiler

The compiler includes header files (e.g., xc.h ) that map SFRs as variables. Ensure you haven't missed a semicolon or used
Whether you are blinking an LED on a PIC16F or running a real-time operating system on a PIC32MZ, the compiler is your most essential partner. Install the latest version, read the error messages carefully, and never stop exploring the optimization flags.
Your code is too large for the selected MCU. Try optimizing your code, removing unused libraries, or upgrading to a chip with more Flash.
