Gmapping can't run
Hello all of ROS users,
I want to use the gmapping to get the X,Y location data and track path data I followed the the website as follows to install it:http://wiki.ros.org/gmapping
But when I type the command "rosrun gmapping slam_gmapping scan:=base_scan" in the terminal, it shows
[rospack] Error: package 'gmapping' not found
Does anyone knows how to solve it? Thank you very much for your kindly help.
