I am getting this error when attempting to build my custom ros2 msg. I followed this tutorial on creating a custom ros2 msg (https://docs.ros.org/en/crystal/Tutorials/Custom-ROS2-Interfaces.html), but when i get to the final step of running:
colcon build --packages-select mbs_ros_msgs
I get the following error:
root@docker-desktop:/home/ros2_ws# colcon build --packages-select mbs_ros_msgs
Starting >>> mbs_ros_msgs
--- stderr: mbs_ros_msgs
