Moodle and Joomla integration problem

Hello,

I am working on joomla 3.1 and I installed joomdle-0.92-for-joomla30/joomdle-joomla-package.zip. There is many modules and plugin in joomdle-0.92-for-joomla30/moodle20 . But I did not installed yet. I am on starting phase. After installing the moodle in joomla one fatel error is coming on User, Course Request, Shop section. Can you help me why this fatal error coming. Fatel error is below

Fatal error: Call to undefined function xmlrpc_encode_request() in \wamp\www\project\administrator\components\com_joomdle\helpers\content.php on line 72

Do you have the xmlrpc libraries installed and enabled? Do you have any error messages in the system health check?

I have also received your two emails with the above information.
