Well done! We have completed the ROS installation for the ARM platform. The ROS scripts and executables are mostly installed in /opt/ros/<ros_version>.
To get access to these scripts and executables, the ROS environment variables need to be added to the bash session. We have to source the following bash file:
$ source /opt/ros/<ros_version>/setup.bash
It's convenient if the ROS environment variables are automatically added to the bash session every time a new shell is launched:
$ echo "source /opt/ros/<ros_version>/setup.bash" >> ~/.bashrc$ source ~/.bashrc
If we have more than one ROS distribution installed, ~/.bashrc must only source the setup.bash for the version we are currently using:
$ source /opt/ros/<ros_version>/setup.bash ...
