Prerequisites

This tutorial assumes that you have installed catkin and sourced your environment. If you installed catkin via apt-get for ROS $ROS_DISTRO, your command would look like this:

$ source /opt/ros/$ROS_DISTRO/setup.bash

Let's create and build a catkin workspace:

$ mkdir -p ~/catkin_ws/src
$ cd ~/catkin_ws/
$ catkin_make

The catkin_make command is a convenience tool for working with catkin workspaces. Running it the first time in your workspace, it will create a CMakeLists.txt link in your 'src' folder. Additionally, if you look in your current directory you should now have a 'build' and 'devel' folder. Inside the 'devel' folder you can see that there are now several setup.*sh files. Sourcing any of these files will overlay this workspace on top of your environment. To understand more about this see the general catkin documentation: catkin. Before continuing source your new setup.*sh file:

$ source devel/setup.bash

To make sure your workspace is properly overlayed by the setup script, make sure ROS_PACKAGE_PATH environment variable includes the directory you're in.

$ echo $ROS_PACKAGE_PATH
/home/youruser/catkin_ws/src:/opt/ros/kinetic/share

Next you should go ahead and learn how to use the workspace.

If you are following the ROS tutorials series instead of the catkin tutorials, please continue with Creating a ROS Package.
