SFML undefined reference to `sf::TcpSocket::TcpSocket()'

Question

I am trying to compile SFML simple code:

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

using namespace std;

int main(int argc, char* argv[])
{

    sf::TcpSocket socket;
    sf::Socket::Status status = socket.connect("127.0.0.1", 6000);
    if (status != sf::Socket::Done)
    {
        // error...
    }
    return 0;
}

All libs and dependencies are installed:

sudo apt-get install libsfml-dev
sudo apt-get build-dep libsfml

I am using two methods:

g++ -c main.cpp
g++ -o main main.o -std=c++11 -lsfml-graphics -lsfml-window -lsfml-system

g++ -c main.cpp -I/home/x64joxer/SFML-2.4.0/include
g++ -o main main.o -L/home/x64joxer/SFML-2.4.0/lib -std=c++11 -lsfml-graphics -lsfml-window -lsfml-system

But I still have the same problem:

main.o: In function `main':
main.cpp:(.text+0x27): undefined reference to `sf::TcpSocket::TcpSocket()'
main.cpp:(.text+0x38): undefined reference to `sf::IpAddress::IpAddress(char const*)'
main.cpp:(.text+0x54): undefined reference to `sf::TcpSocket::connect(sf::IpAddress const&, unsigned short, sf::Time)'
main.o: In function `sf::TcpSocket::~TcpSocket()':
main.cpp:(.text._ZN2sf9TcpSocketD2Ev[_ZN2sf9TcpSocketD5Ev]+0x30): undefined reference to `sf::Socket::~Socket()'
main.cpp:(.text._ZN2sf9TcpSocketD2Ev[_ZN2sf9TcpSocketD5Ev]+0x56): undefined reference to `sf::Socket::~Socket()'
main.o:(.rodata._ZTIN2sf9TcpSocketE[_ZTIN2sf9TcpSocketE]+0x10): undefined reference to `typeinfo for sf::Socket'
collect2: error: ld returned 1 exit status

I read many tutorials and topics at the forum but I still do not know how too fix it. My system is Kubntu 15. Can anyone know how to fix it?

You are linking with graphics, system and window but not with network. Did you try adding -lsfml-network ?
