[ros-users] laser_pipeline tutorial fails to build

[Jeremy Leibs]

Is the code for the tutorial in a package which declares a dependency
on laser_geometry?

Make sure there is a line such as:

  <depend package="laser_geometry"/>

in the manifest file for the package you are using for the tutorial.
