    Are you linking to the appropriate libraries?
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah

    You can only do it in a project. Goto Project Options, then Parameters, click on "Add library and object", add "libwsock32.a"

    blah.. check it .. i ran a sample code in my project and i keep getting the perror ( what am i doing wrong here )

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <windows.h>
    #include <sys/types.h>
    #include <winsock.h>
    #include <errno.h>
    
    int main(int argc, char *argv[])
    {
       struct sockaddr_in socketz;    /* Structure of socket */
       int s_sock;                    /* Socket status */
    
    
       if(( s_sock = socket( AF_INET, SOCK_STREAM, 0 )) == -1 )
       {
         perror( "Error" );
         exit( 1 );
       }
    
       printf( "Socket status: ON!\n" );
       return 0;
    }

    to program in windows sockets, you need to run WSAStartup and WSACleanup, not exactly sure how they work, I use linux, but those functions tell which version of winsock to use so you don't get those undefined errors, probably fixing the perror thing also. try searching here for more on WSAStartup and all
    http://msdn.microsoft.com
    or go to google and search beej, and feel lucky.

    1) You don't need that many header files to run the code you gave
    2) Expand your code to find out what the error is.
    3) chrismiceli is right about WSAStartup() being need

    But if you are getting errors it helps to eliminate all unneeded stuffs. Then go back in and add as you need, that way if you start getting errors again it is easier to figure out what is causing it.
