For every newly opened terminals, why do I have to source setup.bash and execute catkin_make again?
I' m new to ROS, and running ROS kinetic on a raspberry pi 3B with ubuntu installed.
I have noticed that each time I open up a new terminal, I have to source /opt/ros/kinetic/setup.bash and execute catkin_make though I have done so previously in other terminals.
I don' t know whether it is correct to source and catkin_make every time or something has gone wrong. Please help.
