Hi,

So I installed visp_ros package using the instructions here:

http://wiki.ros.org/visp_ros/Tutorials/Howto_install_visp_ros

After the installation i cannot roslaunch a launch file that is in the catkin workspace and worked perfectly before the visp_ros installation. This is the error:

[launchfilename.launch] is neither a launch file in package [packagename] nor is [launchfile_name] a launch file name

And when I go directly to the src and type: roslaunch launchfilename, I get the error:

ERROR: cannot launch node of type packagename/launchfilename]: can't locate node [nodename] in package [cluster_extraction]

I have source /home/username/catkinws/devel/setup.sh in .bashrc file.
