在C语言中,strcpy函数用于将源字符串复制到目标字符串,其声明通常位于<string.h>头文件中。当编译器在编译过程中遇到未声明的函数时,会发出“incompatible implicit declaration of built-in function”的警告。 要解决这个问题,你需要在调用strcpy函数的源文件中包含<string.h>头文件。例如: c #incl...

报错代码:strcpy(temp, (char *)ether_ntoa(LLADDR(sdl)));解决方法: 导入这三个头文件即可, #include<sys/types.h>#include<sys/socket.h>#include<net/ethernet.h>然后上面那行代码会有一个警告:"Incompatible pointer types passing 'caddr_t' (aka 'char *') to parameter of type 'const struct et...
