@dirk-thomas, absolutely right! Would it be more correct to say that **colcon** has been selected as build tool now for ROS2 and ROS1, versus the previously used **cakin_tools** build tool only for ROS1? And that where users in ROS1 one previously used **catkin_make** command now will use the **colcon build** command? Please correct me otherwise so that future readers can have this matter cristal clear. --- [Visit Topic](https://discourse.ros.org/t/ros2-vs-ros1-or-more-like-ros2-ros1/7319/3) or reply to this email to respond.
