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 On Fri, May 14, 2010 at 6:06 AM, John Hsu wrote: > > > On Thu, May 13, 2010 at 11:02 AM, Amy Ng wrote: > >> 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 > > started roslaunch server http://akb:48466/ > > SUMMARY > ======== > > PARAMETERS > * /table_description > > NODES > / > spawn_table (gazebo_tools/gazebo_model) > > ROS_MASTER_URI=http://akb:11311/ > > core service [/rosout] found > process[spawn_table-1]: started with pid [5985] > [ INFO] [33.788000000]: gazebo_model: waiting for gazebo factory, usually > launched by 'roslaunch `rospack find > gazebo_worlds`/launch/empty_world.launch' > [spawn_table-1] process has finished cleanly. > log file: > /u/johnhsu/.ros/log/8e374d24-5eca-11df-b923-00301b81c2e5/spawn_table-1*.log > all processes on machine have died, roslaunch will exit > shutting down processing monitor... > ... shutting down processing monitor complete > done > > > > >> 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 >> >> >> >> amy >> >> >> >> >> >> >> On Fri, May 14, 2010 at 3:26 AM, Joachim Bean wrote: >> >>> Once you apply the patches, ROS works mostly fine on 10.04 >>> >>> -- Joachim >>> >>> On May 13, 2010, at 12:52 PM, John Hsu wrote: >>> >>> looks like you're on lucid.
