Question

大家好！我正在尝试开发 AR 应用，使用C ++服务器和Unity作为客户端。我在C ++服务器和Unity之间使用 WinSock 进行了简单的连接，并发送简单的字符串。现在我尝试将opencv添加到服务器（想法是：它检测标记并将协调发送到Unity）。但是，当我添加opencv libriaries时，服务器停止正常工作（当我启动服务器时，它立即说客户端已连接，但客户端未启动）。所以我不知道该怎么做。这是一个代码：

#include "stdafx.h"
#define _WINSOCK_DEPRECATED_NO_WARNINGS
#pragma comment(lib,"ws2_32.lib")
#include <WinSock2.h>
#include <iostream>
#include <string>
#include "opencv2\core.hpp"
#include "opencv2\imgcodecs.hpp"
#include "opencv2\imgproc.hpp"
#include "opencv2\highgui.hpp"
#include "opencv2\aruco.hpp"
#include "opencv2\calib3d.hpp"

#include <sstream>
#include <iostream>
#include <fstream>
using namespace std;
using namespace cv;
int main() {

    WSAData wsaData;
    WORD DllVersion = MAKEWORD(2, 1);
    if (WSAStartup(DllVersion, &wsaData) != 0) {
        MessageBoxA(NULL, "WinSock sturtup failed", "Error", MB_OK | MB_ICONERROR);
        exit(1);
    }

    SOCKADDR_IN addr; // socket adresy
    int addrlen = sizeof(addr);
    addr.sin_addr.s_addr = inet_addr("100.100.0.1"); //
    addr.sin_port = htons(10101);
    addr.sin_family = AF_INET; //ipv4

    SOCKET sListen = socket(AF_INET, SOCK_STREAM, NULL);
    bind(sListen, (SOCKADDR*)&addr, sizeof(addr));
    listen(sListen, SOMAXCONN);

    SOCKET newConnection;
    newConnection = accept(sListen, (SOCKADDR*)&addr, &addrlen);
    if (newConnection == 0) {
        cout << "Failed to accept the client's connection" << endl;
    }
    else {
        cout << "Client connected!" << endl;
        char MOTD[256];
        string sendData;
        cin >> sendData;
        int i;
        for (i = 0; i < sendData.length(); i++)
        {
            MOTD[i] = sendData.at(i);
        }
        send(newConnection, MOTD, i, NULL);
    }

    system("pause");

    return 0;
}

请注意代码运行良好（没有添加opencv库时）。

添加opencv libriary时，套接字不起作用
