Hi,

I'm new to ROS and have been going through the tutorials and everything seems to work. But I have a couple of questions. When i use rosdep to install the system dependencies I get the following warning and in the end it says #No packages to install. But rosmake works perfectly well and I'm able to run the tutorials. I want to make sure that rosdep is working. The following is the output even if i try to use rosdep against (all) any other packages.

rosdep install turtlesim

#No Packages to install

The second query is, why do I have two installations of ros in my file system. I use ubuntu karmic and I installed the ROS & base using the pre-compiled binaries as told in ROS wiki. I can see ROS and its stacks in opt/ros/boxturtle and in ~/ros/ros with tutorials in ~/ros-tutorials. I get confused when i set the env variables cause I don't know where to set ROS_ROOT. I ran all the tutorials with ~/ros/ros as my ROS_ROOT and it worked fine except for rosdep. So if i want to install a new package, Can i proceed with ~/ros/ros as my ROS_ROOT?. I would be grateful, If somebody could help me with this.
