dir "C:\Program Files\Microchip\xc8\v2.xx\include\xc.h" You should see xc.h along with hundreds of supporting headers (e.g., pic.h , avr.h , i2c.h ).
Add the -I flag to your compile command:
"configurations": [ "name": "XC8", "includePath": [ "$workspaceFolder/**", "C:/Program Files/Microchip/xc8/v2.xx/include" ], "defines": ["__XC8"], "compilerPath": "C:/Program Files/Microchip/xc8/v2.xx/bin/xc8-cc.exe" ] xc.h library download
#include <xc.h> #include <stdint.h> // Configure for PIC16F877A (example) #pragma config FOSC = HS, WDTE = OFF, PWRTE = OFF, BOREN = OFF, LVP = OFF, CPD = OFF, WRT = OFF, CP = OFF
Contrary to what some beginners believe, from a random repository. It is an integral part of the official XC8, XC16, and XC32 compilers from Microchip Technology. This article will walk you through everything you need to know about obtaining, installing, and correctly linking the xc.h header for your embedded projects. Understanding xc.h: The Master Header for PIC and AVR MCUs Before diving into the download process, it’s essential to understand what xc.h actually does. dir "C:\Program Files\Microchip\xc8\v2
Introduction: What is the xc.h Library? If you are a C or C++ developer working on embedded systems, real-time operating systems (RTOS), or automotive software, you have likely encountered the frustrating "fatal error: xc.h: No such file or directory" message. This error indicates that your compiler cannot locate the xc.h library – a critical header file in the Microchip XC series compiler ecosystem.
For Linux/macOS (typical path):
void main(void) TRISB = 0x00; // Set PORTB as output while(1) PORTB = 0xFF; // Turn on LEDs
