rosdep-install and rgbdslam_v2 problem

edit

Two things to mention here,

1. The package name is rgbdslam, not rgbdslam_v2. If you look in the launch files this is how it is referred to. So try running rosdep install rgbdslam.
2. Based on the error output from Rosdep, it doesn't look like you have a catkin workspace setup. Did you clone it into /opt/ros/indigo/share? You should setup a catkin workspace as per the tutorials, http://wiki.ros.org/catkin/Tutorials , clone RGBDSLAM_V2 into there, then you can execute catkin_make to build the package.

Also, I've posted this same response in you previous question, http://answers.ros.org/question/22309... , but I would suggest not repeating the same question in two separate posts. Just stick to one, and if you find the responses helpful mark it as such. That way other users have less posts to look through when looking for answers.
