[ros-users] missing libgazebo_ros_time.so

Hi

it just hangs indefinitely....

what i did was:

run the gazebo in my console with

roslaunch gazebo_worlds empty_world.launch

and the console displays some messages (can't read as they disappaer
too quickly):

and then lots of the same line:

Allocating 16 x 16 radeon RBO (pitch 16)
Allocating 16 x 16 radeon RBO (pitch 16)
Allocating 16 x 16 radeon RBO (pitch 16)
Allocating 16 x 16 radeon RBO (pitch 16)
Allocating 16 x 16 radeon RBO (pitch 16)
Allocating 16 x 16 radeon RBO (pitch 16)

ODE Message 2: inertia must be positive definite in dMassCheck() File
mass.cpp Line 53


and the gazebo gui starts with and empty world,

in the console, i then type:
roslaunch gazebo_worlds table.launch


the prompt just jump to next line with nothing happen, (nothing in the
console or in the GUI)


when i quit gazebo, this comes up:

[gazebo-2] process has died [pid 4810, exit code -11].
and tell me it has been logged

but the console also just hangs there

i need to quit using Ctrl+c


and my log is just:
directory [/tmp/gazebo-tingting-0] already exists (previous crash?)
but the owner gazebo server (pid=4710) is not running.
deleting the old information of the directory [/tmp/gazebo-tingting-0]
Gazebo successfully initialized


Am i missing anything?

thanks

amy
