catkin workspace

CATKIN is an official build system for ROS

cd
mkdir catkin_ws
cd catkin_ws
mkdir src
catkin_make

Alternative is to use catkin build (beforehand you need to remove devel and build folders).

Conect console with ROS variables

cd devel
source setup.bash

To do this automatically when the console is opened, add to bashrc.sh

echo "source ~/catkin_ws/devel/setup.bash" >> ~/.bashrc
source ~/.bashrc
