Workspace Setup

Use the following to setup your workspace

Inorder to setup a workspace you first need to source your ROS2 environment.

source /opt/ros/galactic/setup.bash

Now you need to create a folder to act as a workspace.

mkdir -p ~/test_ws/src
cd ~/test_ws/src

Whenever you make changes to your package run this line to downlod all the dependencies before runnning a build.

cd ..
rosdep install -i --from-path src --rosdistro galactic -y

From the root of your workspace (~/test_ws) run the following command to build your workspace

colcon build

After a successfully build you will see new files and folders (build install log) in your workspace.
