Winsock2 issues

[R.a.B.B.i.T]

I hate errors...

$ gcc -o sck sck.o
sck.o:sck.c:(.text+0x45): undefined reference to `WSAStartup@8'
collect2: ld returned 1 exit status

#include <stdio.h>
#include <windows.h>
#include <winsock2.h>

int main()
{
	WSADATA wsaData;
	
	if(WSAStartup(MAKEWORD(2, 0), &wsaData) != 0)
	{
		printf("Socket failed to init\n");
		return 0;
	}
	printf("Socket init.\n");
	
	return 0;
}

I checked out winsock2.h and WSAStartup() is declared, so I have no idea what's going on. Anyone have any ideas?
