    Errors with including winsock 2 lib

    I've included the ws2_32.lib in my project settings, and the winsock2.h in all of my cpp files, but my server program won't compile.
    I'm using VC++, and heres the errors. They all appear in the winsock.h which has no presence anywhere in my program. I did move to winsock 2 from 1.1 though. I'd also like to say no functions have code in them, its just to test if I set up my window correctly.


    Code:

    I get the same errors if I include winsock.h before winsock2.h. I believe windows.h also includes winsock.h. Try moving that include (if you have it) to after you include winsock2.h.

    Let us make note that every error you posted contains the word "redefinition" I've seen this happen because of ordering of the includes. I forgot how it goes, but fiddle with it.

    EDIT: Yeah, I think JaWiB pinpointed it.

    ...and this is right out of windows.h on my compiler.
    Code:
    #include <winsock2.h>
    /*
     * MS likes to include mswsock.h here as well,
     * but that can cause undefined symbols if
     * winsock2.h is included before windows.h
     */
