这是我的头文件代码。

头文件名16f877a.h

它的代码从此链接获取

我的文件名led.c

#include "16f877a.h" //IC selection
#fuses XT, NOWDT, NOPROTECT, NOLVP
#use delay (clock =20000000) //clock 20MHz
void main(){
    while(1){
        output_B(0xff); //hex to binary output on port B
        delay_us(500); // delay = 500 x clock period.
        output_B(0x00);
        delay_us(500);
    }
}

这些文件位于同一文件夹中

/home/company/Documents/CCPP/PIC/LedProject

我使用UBUNTU 12.04。使用gcc我编译了一个简单的 hello world 程序并且它运行正确。这是我在终端中的命令历史记录

mkdir -p PIC/LedProject
cd PIC/LedProject/
gedit led.c
gcc -Wall -W -Werror led.c -o LedProC

这是我的错误。请帮我解决这个问题

您使用的源代码不是严格意义上C的，而是包含许多预处理器命令的扩展，例如

#fuses XT, NOWDT, NOPROTECT, NOLVP
#use delay (clock =20000000) //clock 20MHz

这些用于配置 PIC 处理器。这种C类似语言的编译器具有对函数的内置理解，例如

delay_us()

您使用的兼容C编译器 (gcc) 不了解 fuse、delay_us 等，因此声明了许多错误。

如果你的目标是编写一个 PIC——我认为是这样，使用这种类型的C，去 MicroChip、CCS 或其他地方并获得他们的 PICC编译器。

如果您的目标是在 UBUNTU 机器上使用 gcc 进行编程，请不要使用为 PIC 设计的代码。

顺便说一句：可能存在在您的 UBUNTU 上编译的 PIC 交叉编译器，但我不知道。

搜索 gcc PIC cross-compiler 的问题，您可能会发现它已得到解答。
