[ros-users] building a map in simulation

[nitinDhiman]

Hi Johh,
Thanks for correcting me.
I tried compiling after downloading  from mentioned link.  But I am not
ablet to find one dependency 'arm_navigation_pr2_app'. It is not present in
trunk_boxturtle. I am getting following messgae : 

nitin at tangri:/opt/ros/boxturtle/wg-ros-pkg/trunk_boxturtle$ rosmake gmapping
pr2_gazebo_wg pr2_teleop rviz 2dnav_pr2
[ rosmake ] Packages requested are: ['gmapping', 'pr2_gazebo_wg',
'pr2_teleop', 'rviz', '2dnav_pr2']

[ rosmake ] Expanded args ['gmapping', 'pr2_gazebo_wg', 'pr2_teleop',
'rviz', '2dnav_pr2'] to:

[ rosmake ] Checking rosdeps compliance for packages gmapping,
pr2_gazebo_wg, pr2_teleop, rviz, 2dnav_pr2.  This may take a few seconds.
[rospack] woah! expanding the dependency tree made it blow up.
 There must be a circular dependency somewhere.
[rosstack] circular dependency
[rosstack] couldn't find dependency [arm_navigation_pr2_app] of
[wg_robots_gazebo]
[rosstack] missing dependency

On trying " roslaunch pr2_gazebo_wg map_building_demo.launch", Gazebo starts
but it immediately crashes. Following is the part of console output::

One more thing I would like to know is " Is there a known better way to find
location of dependent packages?". I spent a lot of time in figuring out
these.

regards
Nitin
