Question

Hi, I am working on a simple turtlebot node that uses baselocalplanner to generate velocity commands. If put the following in my .cpp source file:

#include <base_local_planner/trajectory_planner_ros.h>

The compilation (using catkin_make) fails with the following error message:

[100%] Building CXX object turtlebot_example/CMakeFiles/turtlebot_example_node.dir/src/turtlebot_example_node.cpp.o
In file included from /opt/ros/indigo/include/base_local_planner/world_model.h:41:0,
                 from /opt/ros/indigo/include/base_local_planner/trajectory_planner_ros.h:44,

make[1]: *** [turtlebot_example/CMakeFiles/turtlebot_example_node.dir/all] Error 2
make: *** [all] Error 2

It seems like the error is in some header in ros/indigo/include, which is frustrating.

Answer 1

The missing file is * pcl/point_types.h* . Have you installed pcl?

Ah, I wasn't aware pcl was separate from ROS. That's probably it.

I installed pcl using the instructions here, yet it still fails on that file :(

If that's not good enough, I also have what appear to be several dozen libpcl packages installed, plus ros-indigo-pcl-ros.

Cannot include trajectory_planner_ros.h
