I see, thank you for your answer.
Now I’m trying to implement a graphic interface using Qt for ROS1&2 talker and listener on linux ( select a msg-type then click “publish” or “subscribe” -button that kind of simple GUI).
Using the rclcpp library and std_msg library is straight-forward, but how should I use this “ros1_bridge” library? Is there a document or example codes out there about it?
Thank you!
