I am following the tutorial here to make a simple map from already prepared data:
http://wiki.ros.org/slam_gmapping/Tutorials/MappingFromLoggedData
however, I get stuck at this step:
> rosrun gmapping slam_gmapping> scan:=base_scan
It takes forever, and does not finish. When I abort the process, I see the following on the screen:
> virtual> GMapping::GridSlamProcessor::~GridSlamProcessor():> Start virtual> GMapping::GridSlamProcessor::~GridSlamProcessor():> Deleting tree
I am new to ROS and gmapping, and would appreciate any help here.
