    Winsock compilation errors

    I am new to winsock and went through a tutorial and made a program similar to the one in the tutorial. When compiling no syntax errors or anything but it came up with a list of linking errors. I don't understand this because the linking errors are about the basic commands like WSAStartup, WSACleanup,accept,bind,etc. Here are the errors:
    Code:
    C:\WINDOWS\TEMP\ccz22ggb.o(.text+0x127):winsock.cpp: undefined reference to `WSAStartup@8'
    C:\WINDOWS\TEMP\ccz22ggb.o(.text+0x138):winsock.cpp: undefined reference to `socket@12'

    C:\WINDOWS\TEMP\ccz22ggb.o(.text+0x295):winsock.cpp: undefined reference to `WSACleanup@0'
    I included windows.h, winsock.h, and stdio.h. Do I need to link a library as well or why are these errors coming up?

    With Dev-C++, I need to link these two libraries:

    /Dev-Cpp/lib/libws2_32.a
    /Dev-Cpp/lib/libwsock32.a

    Strangely, my program works fine without #including winsock2.h...hm.

    Thanks, I had a feeling I needed to link some libraries.
