Hi<br><br>I am trying to get the impromtu_buttons up and running. I am new to ROS so am finding my way.<br><br>I am using a clean install of ubuntu 10.4<br><br>Installed using the recently amended instructions to account for eigen3 issues and everything succesfully builds. I paste the three commands into separate terminal windows in the order they are listed on the projects web page and get the following message<br>
