gmapping_demo error [closed]

edit

Hi!

I am currently trying to launch the gmapping_demo to create a map of my environment. I followed the tutorial on this site: http://learn.turtlebot.com/2015/02/01... when entering

roslaunch turtlebot_navigation gmapping_demo.launch

I am getting following output:

before I get some warning but I think thats normal. I did the deb installation and everything else before that part of the instructions is working. The error runs in a loop. I tried to look it up in the internet but did not find anything. Does anyone have any ideas? Thanks!

EDIT: I updated the output code. Maybe the warning are more important than i thought? Should it work with default parameters? Still don't know how to solve this issue...
