# Revision history [back]

My first guess would be that you haven't sourced your workspace. You can do this with the following command in the root of your workspace:

source ./devel/setup.bash


You can also use the rospack command to check that your pacakge has been made and sourced properly

rospack list | grep ouster_ros


should show the package name, if it doesn't show anything then your haven't sourced your workspace. Not this needs doing every time you open a new terminal.

Regarding your final two questions, if you run catkin_make and you don't get any red errors then it should have built okay, if you get a red error then something went wrong. Finally you can name your workspace directory anything you want, as long as it has the correct structure within it, it will work fine.

Hope this helps.
