Create a catkin workspace for the exercise 4.1 ROS1 packages and dependencies. Then it's business as usual: you create an executable, link with dependencies, and install the executable in the lib/ folder of your package (inside the install/ folder of your ROS2 workspace). Unfortunately, after sourcing ./install/local_setup.bash (/opt/ros/ardent/setup.bash was sourced before building), the call ros2 run [package] [executable] returns "No executable found" You should first build everything but the ROS 1 bridge with normal colcon arguments.

Short answer: Packages that you want to be linked by ros1_bridge (without a mapping rule) cannot end in "_interfaces", and that's possibly the only sequence of character's that it can't end with. We build the bridge in a separate workspace because it needs to see both ROS1 and ROS2 packages in its environment and we want to make sure our application workspaces only see the packages from the distribution they are in. I just wanted to let you know. Statistic cookies help website owners to understand how visitors interact with websites by collecting and reporting information anonymously.
