For new package downloading

edit

That tutorial skips over several important preliminary steps. This is the best answer I know. Maybe someone else has a better approach.

Install the ROS binary packages if you have not already (see: Ubuntu C-turtle installation).

Create your own rosinstall file (find_object.rosinstall for this example), containing these three lines:

- other: {local-name: /opt/ros/cturtle/ros}
- other: {local-name: /opt/ros/cturtle/stacks}
- svn: {local-name: find_object, uri: 'https://code.ros.org/svn/wg-ros-pkg/branches/trunk_cturtle/stacks/find_object'}

Run rosinstall on that file, and source the setup.bash script (which you should probably add to your ~/.bashrc script).

You can do all of the above with these shell commands:

$ cp /opt/ros/cturtle/.rosinstall find_object.rosinstall
$ roslocate info find_object >> find_object.rosinstall
$ rosinstall ~/ros find_object.rosinstall
$ source ~/ros/setup.bash

Follow the tutorial after that.
