yes of course. I made my own installation steps. where I can send it to you?

Yes but not following any guide i have made my own steps and it works

I supposed you have tum_ardrone in a workspace.Have you tried to do source .devel/setup.bash in your workspace?

If you do that and it doesn´t work it´s a installation problem.

Yes , it has but I´m installing it on Raspberry pi.

Yes, and I get the same error:

the following packages have unmet dependencies: python-rospkg : Depends: python:any (>= 2.7.1-0ubuntu2) but it is not installable

I think that the error should be in python libraries.

Hi , I'm trying to install ROS Hydro on Raspberry Pi following the steps of the ROS wiki in a new installed version of Raspbian using NOOBS like it says here:

http://wiki.ros.org/ROSberryPi/Settin...

Everything is OK until I do :

sudo pip install -U rospkg sudo apt-get install python-rosdep python-rosinstall-generator build-essential

I get the next error:

Reading package lists... Done

Building dependency tree

Reading state information... Done

build-essential is already the newest version.

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

The following information may help to resolve the situation:

The following packages have unmet dependencies: python-rosdep : Depends: python-catkin-pkg but it is not going to be installed Depends: python-rospkg but it is not going to be installed Depends: python-rosdistro (>= 0.3.0) but it is not going to be installed python-rosinstall-generator : Depends: python-catkin-pkg (>= 0.1.28) but it is not going to be installed Depends: python-rosdistro (>= 0.3.4) but it is not going to be installed Depends: python-rospkg but it is not going to be installed E: Unable to correct problems, you have held broken packages.

How can I install it correctly or correct the error?

Thank you.

I have the boost libraries installed because when I try to install it again it advise me that I have already that library and looking for them in the directory /usr/lib/liboost they appear there. Maybe the error can be in the path where ROS searches the libraries. Thank you for answer.

What are the recommended steps to install ROS Groovy in the Raspberry Pi? Is better to install it by source following the steps shown in the ROS wiki or using the binary packages?

And how can I install new packages in raspberry pi that i don´t have correctly? I´ve tried using the command git clone in the workspace and catkin_make but it doesn´t work correctly. Thank you for answer!

I´ve created a package in ROS Groovy installed on Ubuntu 12.04 with two very simple nodes that communicate sending a float32 to start learning with ROS but what i really need is to implemnet this on raspberry pi.I did the same steps in the two cases and it works on the computer but I get an error during compilation on the raspberry pi package.In the case of the raspberry pi i used leafpad text editor to create the two cpp files. Where may be the error?Are the cpp files created on Leafpad valid?

The error that i get is next>
