Packet receives empty string

[Dean404]

string_to_send = "P";
packetSend << string_to_send << pointer_x << pointer_y;
                                globalMutex.unlock();
                                socket.send(packetSend);

Sending code

if (packetReceive >> new_building >> new_x >> new_y)
                {
                                        map[new_y][new_x] = new_building;                                      
                                        SomethingChanged = true;
                }

Receiving code.
And new_building equals nothing. Please, tell me, what am I doing wrong here. new_x and new_y are all right, though.

I think the new_building has to be char *

Nope, it's still nothing.

Provide a minimal and compilable example code.

Here's the separate programm, that has to send std::string through packet:

#pragma comment(lib, "sfml-network.lib")

#include <iostream>
#include <SFML/Network.hpp>

sf::TcpListener listener;
sf::TcpSocket socket;
sf::Packet packet;
sf::IpAddress ip = sf::IpAddress::getLocalAddress();
std::string text;

void Server()
{
        listener.listen(2000);
        listener.accept(socket);
        text = "Hello";
        packet << text;
        socket.send(packet);
}
void Client()
{
        socket.connect(ip, 2000);
        socket.receive(packet);
        packet >> text;
}
int main()
{
        char who;
        std::cout << "Do you want to be a server (s) or a client (c) ? ";
        std::cin >> who;

        if (who == 's')
                Server();
        else
                Client();

        std::cout << text << std::endl;
        system("pause");

        return 0;
}

And here is the result:

Oh lol, i am so stupid, forgot to add sfml-network.lib. Working fine now.
