TurtleSim [rosrun turtlesim turtlesim_node] doesn't work
I'm new to ROS and I'm trying to progress with the tutorial. Currently running Fuerte on Oneiric.
I was trying rosrun turtlesim turtlesim_node
and it gave me this:
(turtlesim_node:2972): Gtk-WARNING *: Unable to locate theme engine in module_path: "pixmap", (turtlesim_node:2972): Gtk-WARNING *: Unable to locate theme engine in module_path: "pixmap", (turtlesim_node:2972): Gtk-WARNING *: Unable to locate theme engine in module_path: "pixmap", (turtlesim_node:2972): Gtk-WARNING *: Unable to locate theme engine in module_path: "pixmap", and a blue screen with nothing in it. This is what it meant to be: http://www.ros.org/wiki/ROS/Tutorials/UnderstandingNodes
I did run a core and make Turtlesim before running and I don't really know what's going on... Thanks in advance.
P.S. I was reading other posts and some claimed that there is a problem with the tutorials. But those posts were about 2 to 3 yrs old...
