Hi, my name is Enuchul Jeon I'm using the ROS installing on Ubuntu from SVN I want to use scan_tools in ccny-ros-pkg. so I download the source from repository with following command. cd ~/ros/stacks git clone http://robotics.ccny.cuny.edu/git/ccny-ros-pkg.git and next, cd ~/ros/stacks/ccny-ros-pkg rosmake scan_tools --rosdep-install but I see the following error. [ rosmake ] WARNING: The following args could not be parsed as stacks or packages: ['scan_tools'] [ rosmake ] ERROR: No arguments could be parsed into valid package or stack names. Maybe, I need more setting to package but I can't find it. Thank you in advance your help. -- ================================================ Eunchul Jeon M.S.
