我被万恶之源ld returned 1 exit status困住了

最近试着做一个局域网小游戏，结果碰到了 ld returned 1 exit status

//main.cpp
#include
using namespace std;
extern start(double p);
extern activeconnect();
extern unactiveconnect();
int main() {
    start(1.01);
    int n;
    cout<<"主动连接（1）还是被动链接（2）？";
    cin>>n;
    if(n==1) {
        activeconnect();
    } else {
        unactiveconnect();
    }
}

    for(int i=1; i<=p; i++) {
        fin>>arr[i];
    }
    for(int i=1; i<=p; i++) {
        cout<"要开始吗？"<system("pause");
    system("cls") ;

求帮忙，能运行就行

你下面错误underfined reference一看就是DevC++没有链接WinSock的库
这样解决：工具->编译选项->上面那个框填-lws2_32 链接相关库，就好了

报错信息呢，截图呢，瞅瞅是那个文件报错

那里写的是collect2.exe

你的程序是不是正在运行？如果你检查不到，重启一下绝对能好
