我把它归结为一个简单的例子: inline int func(void) { return 0; } int main (int argc, char **argv) { func(); } 代码不使用以下内容进行编译: gcc -o exec code.c # gcc 6.2.1 它失败了,因为: undefined reference to 'func' 我也在同一个东道主上尝试了gcc 4.8,4.9和5,但都失败了。如果...

3.为什么会出现undefined reference to 'xxxxx'错误? 首先这是链接错误,不是编译错误,也就是说如果只有这个错误,说明你的程序源码本身没有问题,是你用编译器编译时参数用得不对,你没有指定链接程序要用到得库,比如你的程序里用到了一些数学函数,那么你就要在编译参数里指定程序要链接数学库,方法是在编译命令行里...
