I am using ROS::HokuyoNode. When I run the node, it stops at the
function: NodeHandle::construct() and the program can not continue. I
trace down and get the following stack for the main thread. The thread
1 is stalled at __lll_lock_wait(). Is this a dead lock problem?
I am using ubuntu, fuerte, boost 1.48. Thanks for any hints.
