Question

我目前正在尝试使用MacOS High Sierra上的GCC编译包含多个文件的项目。由于某些原因，我收到以下错误：

clang: error: linker command failed with exit code 1 (use -v to see invocation)

这是我的代码（我简化了它，因此它更具可读性。我检查过它实际上会产生上面的错误）：

的main.c

#include "myfile.h"

int main(int argc, char *argv[]){
    printf("Hello World!\n");
    myFunction();
    return 0;
}

myfile.h

#include <stdio.h>

void myFunction();

myfile.c文件

#include "myfile.h"

void myFunction(){
    printf("Worked!\n");
}

你知道这个问题可以来自哪里吗？

谢谢！
