cannot compile hector_quadrotor

[wilhem]

Hi, I ve Indigo (Ubuntu 14.10) and I downloaded the hector_quadrotor (indigo_devel) but I cannot compile it. The error I get is:

:~/workspace_ros$ rosdep install --from-path src --ignore-src ERROR: the following packages/stacks could not have their rosdep keys resolved to system dependencies: hector_quadrotor_gazebo_plugins: Cannot locate rosdep definition for [hector_gazebo_plugins] hector_quadrotor_gazebo: Cannot locate rosdep definition for [message_to_tf] hector_quadrotor_pose_estimation: Cannot locate rosdep definition for [hector_pose_estimation] hector_quadrotor_demo: Cannot locate rosdep definition for [hector_gazebo_worlds] hector_quadrotor_description: Cannot locate rosdep definition for [hector_sensors_description]

even if the error was solved here: https://github.com/tu-darmstadt-ros-pkg/hector_quadrotor/issues/4 I did the same but that solution doesn t work. Any help is appreciated! Thanks!!

hector_quadrotor and its dependencies hector_models, hector_gazebo and hector_localization were released just a few days ago in indigo. The packages have not yet been synced to the public repositories.

So you either have to wait a few days or...

• ...temporarily switch to the ros-shadow-fixed variant of the ROS package repository by updating your /etc/apt/sources.list.d/ros-latest.list file to:

  deb http://packages.ros.org/ros-shadow-fixed/ubuntu utopic main

  and then execute sudo apt-get update, rosdep update and rosdep install --from-path src --ignore-src again.

or

• ...add all hector_* dependencies to your catkin workspace, e.g. by merging hector_quadrotor.rosinstall:

  cd ~/workspace_ros/src
  wstool merge https://raw.githubusercontent.com/tu-darmstadt-ros-pkg/hector_quadrotor/hydro-devel/hector_quadrotor.rosinstall
  wstool update

I just noticed that ROS does not provide pre-compiled packages for utopic. I assume you installed everything from source.

In this case you have to try the last option.

Thanks, but it doesn t work neither: I have the error:

ERROR in config: Command requires a target workspace.

Well, it depends on how you created your catkin workspace. The "standard" way to do it is to use tools like wstool, rosinstall or rosinstall_generator to manage the source repositories in the src folder.

If you do not have a src/.rosinstall file yet, simply create one with wstool init. Do not forget to cd into the src folder first (or always add -t src to the wstool command line).

Danke Dir, nur...ist es mir eben gerade aufgefallen, dass ich den Quadrotor auch durch: sudo apt-get install ros-indigo-hector-* installieren kann. Ist es vielleicht nicht der beste Weg?

Vielen Dank nochmal. Gruß

The binary packages of hector_quadrotor for ROS indigo are available in the public repository since yesterday. See http://lists.ros.org/pipermail/ros-users/2014-September/068914.html.

If you don't want to develop or extend hector_quadrotor, the binary packages should be fine.
