Today when I tried to follow the instructions on this website. I was following all the instructions, including downloading ROS library on my system, which is Ubuntu 14.10, installing packages and setting the environment. However, I stopped at 

$ cd ${IBVS_STACK}
$ source setup.sh
$ rospack profile
$ rosdep update
$ cd ${IBVS_WORKSPACE}/src/extStack
$ rosdep install ardrone_autonomy

when I tried to run 

 $ rosdep install ardrone_autonomy

It shows 

ERROR: Rosdep cannot find all required resources to answer your query 
Missing resource ardrone_autonomy

while ardrone_autonomy just locate right in my directory ~/src/extStack. I tried to use export ROS_PACKAGE_PATH=~/src/extStack/ardrone_autonomy but it still doesn't work. Can anyone possibly tell me what happened to this and what should I do with that?

Thanks

It's just a suggestion, I would prefer to comment but I can't.

Have you tried to install directly the missing package? apt-get install ros-*-ardrone-autonomy, where you have to replace '*' with your ROS version (e.g. apt-get install ros-indigo-ardrone-autonomy)

From http://answers.ros.org/question/75241/install-ros-dependencies-from-apt/?answer=75262#post-id-75262 (slightly modified):

If you have a catkin CATKIN_WORKSPACE with some sources checked out and you want all the rosdep dependencies installed use the following

    rosdep install --from-paths CATKIN_WORKSPACE --ignore-src --rosdistro=ROSDISTRO

That said, I suggest in your case:

cd %CATKIN_WORKSPACE%
rosdep install --from-paths WORKSPACE --ignore-src --rosdistro=ROSDISTRO

Besides, ROS has its own very active forum http://answers.ros.org/.
