Velodyne_driver on ROS Melodic. Velodyne_msg error
I have just installed the velodyne_driver. I am able to create point clouds and visualize it in Rviz. I can also subscribe to velodyne_points and see the data.
But when I try to run the basic velodyne node and subscribe to velodyne_packets topic. I get error of velodyne_msg not being built.
I have also posted the same here
This might be an obvious question but have you sourced the workspace with the velodyne package in your second terminal? This is error is caused because rostopic cannot access the custom message types of the velodyne package.
