Ethernet DHCP Library problem

Projects Programming
1

hi i`ve been trying to use this library: http://gkaindl.com/software/arduino-ethernet/dhcp/ to read my tweeter feed but i keep receiving a error "the client class has renamed Ethernet Client", im using a srduino duemilanove with atmega328

this is the code im using:

#include <Ethernet.h>
#include <EthernetDHCP.h>
#include <TextFinder.h>





byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
byte server[] = {128,242,240,20}; // Twitter

char tweet[140];

Client client(server, 80);

TextFinder  finder( client );  
void setup()
{
 
  Serial.begin(9600);
  EthernetDHCP.begin(mac);
}


void loop()
{
  
  if (client.connect()) {
    client.println("GET http://www.twitter.com/statuses/user_timeline/417539585.rss HTTP/1.0");  // twitter rss 
    client.println();
  } 
  else {
    Serial.println("Connection failed");
  } 
  if (client.connected()) {
     // get the last tweet by simply parsing the item and title tags
     if((finder.find("<item>")&&(finder.getString("<title>","</title>",tweet,140)!=0)))
     {  
         Serial.println(tweet);
       
        
           delay(10000);
           }
     }
   } 
    else
      Serial.println("Could not find item field"); 
  }
  else {
    Serial.println("Disconnected"); 
  }
  client.stop();
  client.flush(); 
  delay(60000); 
}

thks

That's because in the current version of the Ethernet library, the Client class has been renamed to EthernetClient.

thks

this schould work a little better
you can read more at Ethernet - Arduino Reference

thank you it worked, but now im getting these messages:

You don't need a separate library for DHCP. It is supported directly by the Ethernet Library.

Thank you it worked just fine! i`m fairly new to arduino so thanks for answering my questions.
