Hi, I want to know the class of message giving message type via following one code line. I run this python node on(Fuerte/Ubuntu 12.04) and get following error while the same code does not give any error when I run it on (electric Ubuntu 10.04).

error:

msg_class = roslib.message.get_message_class(self.topic_type)
AttributeError: 'module' object has no attribute 'message'

Do I need to update roslib?

Thanks

You need to have the following import:

import roslib.message

(not just import roslib).

roslib.message.get_message_class is definitely provided by Fuerte's roslib. Did you maybe just forget to import it?

import roslib.message
