When I want to get number of frame per second in ROS, I get this this message:

daliranif@NRC-021902:~$ rostopic hz /livox/lidar
ERROR: Cannot load message class for [livox_ros_driver/CustomMsg]. Are your messages built?

How can I fix this?

I catkin_make again and used source ./devel/setup.sh again. It was fixed.
