c++11 threads, SFML and code::blocks

Question

I'm trying to run this code using c++11 std::thread and the SFML library for networking, however I just cant get it to build. I'm pretty sure it has something to do with how I'm setting up the compiler, but I don't know... How can I get this to work? I've been messing about trying to get this to work, going through tutorials and such for hours now, so I have turned to Stack Overflow for answers. I'm using the code::blocks IDE and the x32-4.8.1-posix-dwarf-rev5 compiler on a windows7 64-bit machine.

#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;
}

This is what the build debug log is saying:

Answer 1

I had a simular problem and how i solved this on a Linux system was: Project / build options

Go to linker settings tab. there i added: sfml-network

Done. Hope it helps
