Question

我正在尝试使用c ++ 11 std::thread和用于网络的SFML库来运行此代码，但是我无法构建它。我很确定它与我如何设置编译器有关，但我不知道......我怎么能让它工作？我一直在努力让这个工作，现在通过教程等几个小时，所以我转向Stack Overflow寻求答案。我在windows7 64位机器上使用code :: blocks IDE和x32-4.8.1-posix-dwarf-rev5编译器。

#include <iostream>
#include <thread>
#include <string>
#include <SFML/System.hpp>
#include <SFML/Network.hpp>


using namespace std;

void doNetwork() {
    cout << "Starting..." << endl;

    sf::TcpListener listener;
    listener.listen(88);

    // Wait for a connection
    sf::TcpSocket socket;
    listener.accept(socket);
    cout << "New client connected: " << socket.getRemoteAddress() << endl;

    // Receive a message from the client
    char buffer[1024];
    size_t received = 0;
    socket.receive(buffer, sizeof(buffer), received);
    cout << "The client said: " << buffer << endl;

    // Send an answer
    string message = "Welcome, client";
    socket.send(message.c_str(), message.size() + 1);
}

int main()
{
    thread task(doNetwork);
    task.join();
    return 0;
}

这是构建调试日志所说的内容：

我在编译器中使用的设置：

编译器标志：

-std=C++0x

其他选择：

-std=gnu++0x -U__STRICT_ANSI__

定义：

SFML_STATIC

链接器设置：

sfml-system-s-d
sfml-network-s-d

搜索目录 - 编译器：

C:\Users\user\CppProjects\SFML-2.1\include

我有一个类似的问题，我在Linux系统上如何解决这个问题：项目/构建选项

转到链接器设置选项卡。我添加了：sfml-network

完成。希望它有所帮助

c ++ 11个线程，SFML和code :: blocks
