Hi, I've added the path, but it is still problematic. Any thoughts?  Below is the output from the terminal. Thanks in advance. shah@shah-laptop:~$ export ROS_PACKAGE_PATH=/opt/ros/cturtle/stacks shah@shah-laptop:~$ svn co http://svn.mech.kuleuven.be/repos/orocos/trunk/kul-ros-pkg/srl_people_tracker_0.2/ A    srl_people_tracker_0.2/manifest.xml A    srl_people_tracker_0.2/CMakeLists.patch A    srl_people_tracker_0.2/CMakeLists.txt A    srl_people_tracker_0.2/Makefile Checked out revision 32566. shah@shah-laptop:~$ rosmake srl_people_tracker_0.2 [ rosmake ] Packages requested are: ['srl_people_tracker_0.2']                  [ rosmake ] Logging to directory/home/shah/.ros/rosmake/rosmake_output-20100825-150825 [ rosmake ] Expanded args ['srl_people_tracker_0.2'] to: []                     [ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['srl_people_tracker_0.2'] [ rosmake ] ERROR: No arguments could be parsed into valid package or stack names. --- On Tue, 8/24/10, Tully Foote wrote: From: Tully Foote Subject: Re: [ros-users] Problem with a Package Installation To: ros-users@code.ros.org Date: Tuesday, August 24, 2010, 11:24 PM Shahmi, You need to add the package which you have checked out into your ROS_PACKAGE_PATH environment variable so that rospack can find it.  http://www.ros.org/wiki/ROS/EnvironmentVariables I suggest that you try working through the ROS Tutorials at http://www.ros.org/wiki/ROS/Tutorials which explains how to use the core tools.  After you have worked through the tutorials downloading an arbitrary package will be much easier.   Tully On Tue, Aug 24, 2010 at 2:08 PM, shahmi wrote: Hi, Thanks a lot Tinne for the guide. However, I am having the installation problem. Below is the output after doing what you have suggested. BTW, I am currently running cturtle. Do you have any idea regarding this? I also have tried to "cmake" first prior to "rosmake", but still with no luck. Thanks in advance.

It seems that it was complaining about "srl_source" but I've given so many tries by replacing the term "srl_source" with my "srl_people_tracker_0.2" directory which is /home/shah/Downloads/srl_people_tracker_0.2. Any help is highly appreciated.. Do not run just cmake, the code is not downloaded yet! Just use the rosmake command: rosmake srl_people_tracker_0.2 This will download the code and build and install everything. Tinne PS: if you are using cturtle you will likely get a problem: just let me know   _______________________________________________ ros-users mailing list ros-users@code.ros.org https://code.ros.org/mailman/listinfo/ros-users -----Inline Attachment Follows----- _______________________________________________ ros-users mailing list ros-users@code.ros.org https://code.ros.org/mailman/listinfo/ros-users _______________________________________________ ros-users mailing list ros-users@code.ros.org https://code.ros.org/mailman/listinfo/ros-users -- Tully Foote Systems Engineer Willow Garage, Inc. tfoote@willowgarage.com (650) 475-2827 -----Inline Attachment Follows----- _______________________________________________ ros-users mailing list ros-users@code.ros.org https://code.ros.org/mailman/listinfo/ros-users
