Configurar Smarty

[avargasc1]

Bueno, ya no me da error el archivo de prueba, pero ahora estoy siguiendo el tutorial de la pagina de: Smarty y no mefunciona.

tengo este codigo:

index.php

<?php

/**
* Project: Guestbook Sample Smarty Application
* Author: Monte Ohrt <monte [AT] ohrt [DOT] com>
* Date: March 14th, 2005
* File: index.php
* Version: 1.0
*/

// define our application directory
define('GUESTBOOK_DIR', '/guestbook/');
// define smarty lib directory
define('SMARTY_DIR', 'C:\smarty\libs');
require(SMARTY_DIR . '\Smarty.class.php');
// include the setup script
include(GUESTBOOK_DIR . 'libs/guestbook_setup.php');

// create guestbook object
$guestbook =&new Guestbook;

// set the current action
$_action = isset($_REQUEST['action']) ? $_REQUEST['action'] : 'view';

switch($_action) {
case 'add':
// adding a guestbook entry
$guestbook->displayForm();
break;
case 'submit':
// submitting a guestbook entry
$guestbook->mungeFormData($_POST);
if($guestbook->isValidForm($_POST)) {
$guestbook->addEntry($_POST);
$guestbook->displayBook($guestbook->getEntries());
} else {
$guestbook->displayForm($_POST);
}
break;
case 'view':
default:
// viewing the guestbook
$guestbook->displayBook($guestbook->getEntries());
break;
}

?>


y me da error:

PHP Warning: include(/guestbook/libs/guestbook_setup.php) [function.include]: failed to open stream: No such file or directory in C:\inetpub\wwwroot\Guestbook\index.php on line 17 PHP Warning: include() [function.include]: Failed opening '/guestbook/libs/guestbook_setup.php' for inclusion (include_path='.:c;\smarty\libs') in C:\inetpub\wwwroot\Guestbook\index.php on line 17 PHP Fatal error: Class 'Guestbook' not found in C:\inetpub\wwwroot\Guestbook\index.php on line 20


----------------------------------------

la revise en el archivo :guestbook_setup.php y no se donde esta el error.

PHP Notice: Use of undefined constant GUESTBOOK_DIR - assumed 'GUESTBOOK_DIR' in C:\inetpub\wwwroot\Guestbook\libs\guestbook_setup. php on line 11 PHP Warning: require(GUESTBOOK_DIRlibs/sql.lib.php) [function.require]: failed to open stream: No such file or directory in C:\inetpub\wwwroot\Guestbook\libs\guestbook_setup. php on line 11 PHP Fatal error: require() [function.require]: Failed opening required 'GUESTBOOK_DIRlibs/sql.lib.php' (include_path='.:c;\smarty\libs') in C:\inetpub\wwwroot\Guestbook\libs\guestbook_setup. php on line 11
