Compiling simple C++ SFML file with network code using MinGW throws error "undefined reference to IpAddress"

Question

I keep getting errors when compiling a C++ project using SFML 2 on Windows using MinGW.

At C:\MinGW\include\ there is the SFML header files folder including Network.hpp and I also copied the libsfml-[...].a files into C:\MinGW\lib\ as well as the sfml-[...]-2.dll files into C:\MinGW\bin\.

This is my sample file:

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

int main(int argc, char** argv)
   {
   sf::TcpListener listener;

   listener.listen(4444);

   sf::TcpSocket client;

   std::cout << "Waiting for client to connect..." << std::endl;

   if (listener.accept(client) == sf::Socket::Done)
      {
      std::cout << "Client connected: " << client.getRemoteAddress() << std::endl;
      listener.close();
      }
   else
      {
      std::cout << "Client didnt connect" << std::endl;
      }

   return 0;
   }

If I try to compile it using the following command

g++ test.cpp -lsfml-system -lsfml-network

I get these errors:

C:\Users\me\AppData\Local\Temp\cc6XzH1R.o:test.cpp:(.text+0x28): undefined reference to `_imp___ZN2sf9IpAddress3AnyE`
C:\Users\me\AppData\Local\Temp\cc6XzH1R.o:test.cpp:(.text+0x3a): undefined reference to `_imp___ZN2sf11TcpListener6listenEtRKNS_9IpAddressE`

Thanks for any help :D

Simple , try to link correct version of library. If you are making x86 app use the 32bit version of library and if you are making x64 app use 64bit version. I also got the same error and this fixed.
