If you are a newbie with ROS, we don't recommend building packages that are in trunk as they are usually unstable. Instead, we recommend using the packages that are available with our basic ROS installation: http://www.ros.org/wiki/ROS/Installation If you have questions about specific packages that are not available with those installation options, we can provide assistance with those. The usual process with those is to check them out and type "rosmake " - Ken On Tue, Mar 23, 2010 at 1:16 AM, Vu Hong Thuan wrote: > Hi all, > I'm newbie with ROS. > I want to test some packages existing in trunk.
