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! --- [Visit Topic](https://discourse.ros.org/t/ros1-bridge-in-binaries-files/2380/7) or reply to this email to respond.
