How to build catkin workspaces on ros2

On some courses on theconstructsim I have seen that there are catkin_ws’ along with ros2_ws.
Am I able to use both on my system? How do I add a library meant for ros1 in the catkin_ws on my ros2 humble system and link them together?
Or is this not possible

Hi @oei.nick

Sure, you can use both, just remember to set the workspace inside the shell you’re using.

Regarding bridging ROS1 and ROS2, you could see the ROS Bridge topic.
