I use Code :: Blocks, MinGW and Windows. I am trying to initialize winsock so that I can work on a project. I keep getting the error Undefined Reference to WSAStartup@8Does anyone know how to fix this?

#include <stdio.h>
#include <stdlib.h>

#pragma comment(lib,"ws2_32.lib")

int main(int argc , char *argv[]){
    WSADATA wsa;
    int output;

    output=WSAStartup(MAKEWORD(2,2),&wsa);
    if(output != 0) {
        printf("Startup failed %d\n", output);

You can check yours compiler options, add -lws2_32in add linker options when linking. I use TDM-GCC, works well after that.
