I don't know what I did wrong, but suddenly almost nothing ROS works for me. Running Ubuntu Karmic (64-bit) and ROS boxturtle binary install. All up to date. $ rosmake Segmentation fault $ echo $PYTHONPATH /opt/ros/boxturtle/ros/core/roslib/src $ python Python 2.6.4 (r264:75706, Dec 7 2009, 18:43:55) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> from ros import rosmake Segmentation fault This seems to happen for any ROS python script I try. Any clues what to look at next? -- joq
