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.

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.

Hi,

I've been trying to install the package "srl_people_tracker_0.2" found from "http://www.ros.org/browse/details.php?name=srl_people_tracker_0.2" for several days. Unfortunately, I have not yet got got it installed in my local machine.

These are my tweaks and their corresponding output:

CMake Error at CMakeLists.txt:4 (add_subdirectory):
add_subdirectory given source "srl_source" which is not an existing
directory.

-- Configuring incomplete, errors occurred!

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
