Build does not success

[wangzizhe]

Hi,

build of this package does not success for me, when I run

colcon build --packages-select openrobotics_darknet_ros

I got these error messages:

Starting >>> openrobotics_darknet_ros

Could you please give me a hint how could I build it without error?

Thanks a lot in advance!

It looks like vision_msgs has changed. bbox.center.y would now be bbox.center.position.y etc.

https://github.com/ros-perception/vision_msgs/blob/ros2/vision_msgs/msg/Pose2D.msg

You'll need to modify the source code of this package to match the vision_msgs changes. A PR would be welcome if you're willing.
