my system is ubuntu11.10,installed with ROS( electric) and openni_kinect.

I want to use the mit kinect demo,then I fellow the guide from http://www.ros.org/wiki/openni/Contests/ROS%203D/Customizable%20Buttons

1.I first perform the General Installation.

2.environment is setup, run:

"rosmake impromptu_buttons"

then, terminal display that:

[ rosmake ] Packages requested are: ['impromptu_buttons'] [ rosmake ] Logging to directory/home/jung/.ros/rosmake/rosmake_output-20120604-205316 [ rosmake ] Expanded args ['impromptu_buttons'] to: [] [ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['impromptu_buttons'] [ rosmake ] ERROR: No arguments could be parsed into valid package or stack names.

It seems rosmake is unable to find the package. I should add the path to my ROS_PACKAGE_PATH. How I add the path?

This is identical to your previous question - you should close one or the other. Also, you might want to indicate what you've tried to do on your own to figure this out. Did you read the documentation I linked to in your previous question? What didn't make sense?

If you were following this tutorial, just put all ros packages in the directory ~/ros_workspace.

However, I recommend using rosws. It provides a more structured way to manage local checkouts of ROS repositories and the ROS_PACKAGE_PATH.

If you're using electric, run

vim ~/setup.sh

and add the following lines (this is what mine looks like, you may need to change yours slightly)

#!/bin/sh

source /opt/ros/electric/setup.bash

export ROS_ROOT=/opt/ros/electric/ros

export PATH=$ROS_ROOT/bin:$PATH

export PYTHONPATH=$ROS_ROOT/core/roslib/src:$PYTHONPATH

export ROS_PACKAGE_PATH=/opt/ros/electric/stacks:~/ros_workspace:$ROS_PACKAGE_PATH

then, execute

. ~/setup.sh

If you're package is in /opt/ros/electric/stacks or ~/ros_workpace, ROS should be able to find it.

This is actually not the recommended way of configuring ROS and it will only work for electric and earlier versions. ROS_ROOT, PATH, PYTHON_PATH and ROS_PACKAGE_PATH are already set by /opt/ros/<distro>/setup.bash. For Fuerte, you have to set ROS_WORKSPACE as mentioned in the tutorial.

Deprecated maybe, but this method works in both Fuerte and Groovy for me.
