Hi

i m using Radeon X1950 (open source ATI driver, the one come with Ubuntu 32bit Lucid) , on the list it said X1600 was fine, so I thought my card might be able to run it, and i can run Ogre with no major issues....

:( if it is the graphic card.....

hmmm.......i'll see what I can do about it.....

Thanks so much for your replies

Hi Amy,
what kind of graphics card/driver are you using? Some of the older radeon cards are not supported, please take a look here for some references.

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

Hi thanks guys

it works! :D but i have a few questions

when i tried to run the .patch as patch < pr2_controllers.patch at ros/stacks/pr2_controllers/
it said the patch output only garbage
at then end i need to manually edit every file

was i doing anything wrong?

(roscd pr2_controllers; patch -p0 -N < pr2_controllers.patch;)
and

I got the empty world launched

and in the tutorial it said then add a table by typing
roslaunch gazebo_worlds table.launch

just wondering where do i type this in?
any console with ROS environment variables setup should work.
i tried in the console but nothing happened...
Does the command just hang indefinitely?

typical response to the script looks like this:

> roslaunch gazebo_worlds table.launch
... logging to /u/johnhsu/.ros/log/8e374d24-5eca-11df-b923-00301b81c2e5/roslaunch-akb-5966.log

any advice for a newbie like me?



thanks soooo much, I have spent 2 weeks trying to get gazebo to work and this is the first time i see it running!

thanks again :D

Once you apply the patches, ROS works mostly fine on 10.04

looks like you're on lucid. You'll need to apply patches here or switch to svn trunk/1.0 branch for stacks pr2_controllers and pr2_mechanism, or wait for the next release of these stacks.

Hi Amy,
libgazebo_ros_time.so is in gazebo_plugins. So most likely gazebo_plugins did not compile correctly. Also, can you point me to the exact commands you used to bring up the world?
thanks,
John
