Hi John,
I've attached stap1.world (apparently something went wrong with
attaching it to the first mail).
I'm running Gazebo on two setups.
(1) The first is a VM Player setup (don't laugh).
From /var/log/xorg.log:
(--) PCI:*(0:0:15:0) 15ad:0405:15ad:0405 VMware Inc Abstract SVGA

Adapter rev 0, Mem @ 0xd0000000/1

EndSection
Section "Screen"

Device "Builtin Default vmware Device 0"
EndSection
dmesg tells me that the segfault occured in "libdricore.so".
(2) The second setup is also a very fast one:

I was accessing this second machine using vncserver. Then I had the
same problem. Also here dmesg tells me that "libdricore.so" causes
the
problem.
Inspired by your question, I run Gazebo while I was logged on
directly (from the console) this afternoon. Than it actually ran
successful! Apparently some problem with the (lack off) hardware
acceleration?
Thanks,
Barry

Hi Barry,
To help diagnose the problem, can you attach stap1.world?
also, what graphics card and driver are you using?
thanks,
John

Hi
everybody,
I'm trying to simulate some simple models with simple shapes but
get
segfaults in the visualisation part. The model contains a simple
plane, cylinder and directional light. I've attached the file
"stap1.world" that I'm using. When I'm starting gazebo with
stap1.world, Gazebo crashes with a segfault after successful
initialization. I tried this with several basic shapes (box,
cylinder,
cone, tube) but get the same behaviour. I've also tried it on
different machines with the same behaviour.
The part in the world file which is causing the trouble is:
unit_cylinder
Gazebo/RustyBarrel
If I remove this part from the world file, the gazebo does not
crash. But of course I don't see the cylinder.
Bug 2870446 might be related. But the patched file is no longer
part
of the trunk.
I'm not sure if this is a bug in Gazebo, Ogre or in one of
drivers.
Or if the world model is plainly wrong. Hopefully somebody can help
me
with this one as it's really blocking for me and I'm pulling my
hair
out.
Here's some more info:
- Gazebo trunk rev 8622
- Ogre 1.6.4
- gcc 4.4.3
For more information I've included below (1) world file; (2)
terminal output Gazebo; (3) output of gdb showing where the
segfault
occurs.
Thanks,
Barry
This is the output I get from the terminal:
$gazebo stap1.world
