[ros-users] laser_pipeline tutorial fails to build

[Lisa Miller]

I'm trying to work on the IntroductionToWorkingWithLaserScannerData
tutorial and cannot get the given code to compile. It is having
trouble with laser_geometry.h

If I try to make the code as is I get this error:
laser_scan.cpp:6:43: error: laser_geometry/laser_geometry.h: No such
file or directory

rospack find can find laser_geometry

If I code in the full path to laser_geometry. h
#include "/opt/ros/cturtle/stacks/laser_pipeline/laser_geometry/include/laser_geometry/laser_geometry.h"

Then I get all sorts of compiler errors:

I've tried reinstalling laser_pipeline from both svn and Ubuntu
packages but it doesn't change these errors.
