RLException Ubuntu 18.04 ROS

[jgamblin]

I just got the open lidar hardware and after following the information on the installation page I am getting the following error:

RLException: [xaxxon_openlidar.launch] is neither a launch file in package [xaxxon_openlidar] nor is [xaxxon_openlidar] a launch file name
The traceback for the exception was written to the log file

Any thoughts on what I am doing wrong?

I may have stumbled on this direction block because it is misformatted and I am not sure what para
bq(cb) is.

Change to workspace root and build all the packages using catkin_make:
using this para
bq(cb).

$ cd ~/catkin_ws/
$ catkin_make

Apologies, you're right there was a glitch in the docs formatting! Should be fixed now.
try switching to catkin_ws folder and running catkin_make again

I am sorry but it is now failing on the catkin_make

...also happy to open another issue if you would like me to.

sounds like a workspace setup issue, sent DM
