[kinetic-devel] Segmentation Fault When Launching Gazebo Simulator

[kphawkins]

I'm trying to run the Gazebo simulator after a fresh install and getting a crash every time:

Gazebo works fine when launching independently so I don't believe it's a graphics card/driver issue. I believe it happens when starting the gazebo server and might be related to an invalid URDF model.

Ubuntu 16.04 ROS Kinetic Gazebo 7.9.0 Branch: kinetic-devel

It does appear that the autoRallyTrackMultipleCarsGazeboSim.launch works properly. I can reverse engineer a single car version in the coming days.

[karanchawla]

Try killall gzserver && killall gzclient before launching the simulation.

I was able to get this working on two different machines using the code in gazebo_fixes. Let me know if you are still having issues launching on that branch.

That works just fine. Thanks!
