[gnet-devel] GNet, compile errors.

["Piotr Mackiewicz" <pietrzuch gmail com>]

Hello,
I installed GNet library and i'm using Code::Blocks. I have got errors
in compile my programs from examples. Help me in use GNet, please.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <iostream>
#include <glib.h>
#include <gnet.h>


int main()
{
   gnet_init();
   //nasz gniazdko
   GUdpSocket *mysocket = NULL;
   GInetAddr *addr = NULL;
   mysocket = gnet_udp_socket_new();
   addr = gnet_inetaddr_new("www.schat.hopto.net/",1323);
   gchar bufor[1024];
   gint zapis_l;
   do
   {
        //odbior
        zapis_l =gnet_udp_socket_receive(mysocket, bufor,
sizeof(bufor), &addr);
        //wyswietlanie
        std::cout<<"Odebrano"<<zapis_l;
   }while(zapis_l = 0);

 gnet_inetaddr_delete (addr);
 gnet_udp_socket_delete (mysocket);
}

I have got errors in the example code too:

I had other codes, and i remember i had got error with no class "GUdpPacket".
Please, help me in compile programs.

Best regards, Peter.
