Hi, I'm sorry but now I'm not in front of that computer, hence I can't be very precise. By the way, I installed ROS and Open Rave through the following tutorial http://openrave.programmingvision.com/index.php/Installation. I'm using Linux X-Ubuntu 10.4 on a x86, updated to the last kernel version. The problem is that the computer starts to respond very slowly to any mouse/keyboard input. After at least an hour the pc closes the terminal window and stops the compilation. I waited the entire night but the compilation failed. Now I solved the problem. I launched the system without the graphic interface, then I compiled rviz with the "make" command, and finally i run the command "rosmake rviz". Thank You. -- View this message in context: http://ros-users.122217.n3.nabble.com/Rviz-installation-tp1664434p1666944.html Sent from the ROS-Users mailing list archive at Nabble.com.
