melodic gmapping
I installed melodic on Ubuntu 18.04.
This is the first time to use ROS for me.
I wished to do SLAM with slam_gmapping.
I am trying to build slam_gmapping since I could not find apt-get package "ros-melodic-slam-gmapping".
To build "ros-melodic-slam-gmapping", It is seems to necessary to prepare for "ros-melodic-openslam-gmapping".
But I could not find apt-get package "ros-melodic-openslam-gmapping".
I cloned the source-code of openslam_gmapping from the following.
https://github.com/OpenSLAM-org/openslam_gmapping
Is this really a right(easiest) way to do SLAM?
Why couln't I find these packages in apt-get?
