undefined reference to `DoServerTCP(unsigned short)'

[TobiasSmollett]

Hi there,
I'm new here so forgive my ignorance...
I'm trying to run this code ion codeblocks:

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

////////////////////////////////////////////////////////////
// Function prototypes
// (I'm too lazy to put them into separate headers...)
////////////////////////////////////////////////////////////
void DoClientTCP(unsigned short Port);
void DoClientUDP(unsigned short Port);
void DoServerTCP(unsigned short Port);
void DoServerUDP(unsigned short Port);


////////////////////////////////////////////////////////////
/// Entry point of application
///
/// \return Application exit code
///
////////////////////////////////////////////////////////////
int main()
{
    // Choose a random port for opening sockets (ports < 1024 are reserved)
    const unsigned short Port = 2435;

    // TCP or UDP ?
    char Protocol;
    std::cout << "Do you want to use TCP ('t') or UDP ('u') ? ";
    std::cin  >> Protocol;

    // Client or server ?
    char Who;
    std::cout << "Do you want to be a server ('s') or a client ('c') ? ";
    std::cin  >> Who;

    if (Who == 's')
    {
        // Run as a server
        if (Protocol == 't')
            DoServerTCP(Port);
        else
            DoServerUDP(Port);
    }
    else
    {
        // Run as a client
        if (Protocol == 't')
            DoClientTCP(Port);
        else
            DoClientUDP(Port);
    }

    // Wait until the user presses 'enter' key
    std::cout << "Press enter to exit..." << std::endl;
    std::cin.ignore(10000, '\n');
    std::cin.ignore(10000, '\n');

    return 0;
}
 

I have imported the right stuff, i think: sfml-networking-d.

But i still get the error:

undefined reference to `DoServerTCP(unsigned short)'

Can you help?

By the way, I have it in the right order too, to the best of my knowledge...

Did you implement the function anywhere? If it's in another source file you have to add that file to your project too.

The "Sockets" example is made of multiple source files. You need all of them to compile it.
