我正在尝试编译一个非常简单的程序,我不明白为什么它不能编译。这是我的程序:
/* General includes */
#include <stdio.h>
#include <stdlib.h>
#include <libpic30.h>
#include <p33FJ128GP804.h>
#include "RunLengthAlgorithm.h"
//#include "RunLengthAlgorithm.c"
int main(void) {
int n;
char source[10001];
char target[100];
for(n = 0; n < 1000; ++n){
source[n] = "A";
}
for(n = 1000; n < 2000; ++n){
source[n] = "B";
}
for(n = 2000; n < 3000; ++n){
source[n] = "C";
}
for(n = 3000; n < 4000; ++n){
source[n] = "D";
}
for(n = 4000; n < 5000; ++n){
source[n] = "E";
}
for(n = 5000; n < 6000; ++n){
source[n] = "F";
}
for(n = 6000; n < 7000; ++n){
source[n] = "G";
}
for(n = 7000; n < 8000; ++n){
source[n] = "H";
}
for(n = 8000; n < 9000; ++n){
source[n] = "I";
}
for(n = 9000; n < 10000; ++n){
source[n] = "J";
}
source[10001] = '\0';
RLEncode(&source, &target);
while(1);
return (EXIT_SUCCESS);
}
.h 和 .c 文件被添加到项目中。
#ifndef RUNLENGTHALGORITHM_H
#define RUNLENGTHALGORITHM_H
void RLEncode (char *source, char *target);
#endif
和 .c 文件:
#ifndef RUNLENGTHALGORITHM_C
#define RUNLENGTHALGORITHM_C
void RLEncode (char *source, char *target){
int n, k = 0;
for(n = 0; source[n] != '\0'; ++n){
int length = 1;
while(source[n+1] != '\0' && source[n] == source[n+1]){
++length; ++n;
}
target[k++] = length;
target[k++] = source[n];
}
source[n] = '\0';
}
#endif
我正在使用带有 C30 编译器的 MPLAB-X IDE,它给了我这个错误:

我不明白为什么,如果我将我的函数放在 Main.c 中并且我不包含 #include "RunLengthAlgorithm.h" 它可以工作,但我无法让它工作包括一个文件。
