Cannot build a map from LMS100

Hello, I have to implement a LMS100 on ROS for my lab. I succeed to install a driver to get the scan and I can plot it on RVIZ. (the package I am using is not working very well, I can only scan the half right but the latest version I have found only scan once and then stop :LMS1xx). But this is not my big issue, the first package creates a topic /scan (which works) and I am using it to call gmapping: rosrun gmapping slam_gmapping scan:=/scan But then it generates several topics which are "empty". And the terminal write down this:

[ WARN] [1428030742.039476635]: MessageFilter [target=odom ]: Dropped 100.00% of messages so far. Please turn the [ros.gmapping.message_notifier] rosconsole logger to DEBUG for more information.

I have checked with rqt_graph to see if the connection between the laser and slamgmapping was created and it seems yes. Could you help me to find out why slamgmapping is not publishing?

Thanks
