Hi folks.

I'm starting with panda and python on a gentoo_x64 system. I compiled panda my own with the latest cvs tree (date 11.Sep).
So I started coding and got a segfault while importing DirectStart.

Code: Select all: import direct.directbase.DirectStart

yes, thats all the code

and i get this output

Code: Select all: localhost panda3d% python main.py DirectStart: Starting the game. Known pipe types: glxGraphicsPipe (all display modules loaded.) zsh: segmentation fault python main.py

i compiled panda with

Code: Select all: makepanda/makepanda.py --everything --optimize 3 --no-jpeg --no-max2011 --no-max2010 --no-max2009 --no-max9 --no-max8 --no-max7 --no-max6 --no-maya2011 --no-maya2010 --no-maya2009 --no-maya2008 --no-maya85 --no-maya8 --no-maya7 --no-maya65 --no-maya6

could somebody help? any hint on how to debug this would also help.

greetings

I would start by running pview, just to prove you get the same segment fault there.

Then I would change "load-display pandagl" to "load-display tinydisplay" to see if you get a segment fault then. If you don't, then there is probably something wrong with your OpenGL drivers. Do other 3D applications run successfully? Can you update your drivers?

pview produces the same segfault.
where do i set the "load-display" driver?
i already have the newest drivers; btw its a Intel X4500 gpu
all other openGL applications run fine. i used another engine before i started with panda and opengl ran fine.

by **drwr** » Sat Sep 11, 2010 12:58 pm

The setting is made in your Config.prc file.

OpenGL provides several different interfaces to open a window in X11. It may be that Panda's choice of interfaces happens to be buggy in your drivers, whereas another pathway would work fine. It's difficult to speculate from here. Are you familiar enough with C++ to research this further in the source code?

David

by **nurbs999** » Sat Sep 11, 2010 6:56 pm

tinydisplay works, i only get the segfault when using opengl.
i am familiar enough to C++ but since this is my first day with panda (oh, the second day has just begun

) i appreciate any help with fixing the pathway.

i set the notify level to debug and got this right before the segfault

Segmentation fault

by **drwr** » Sun Sep 12, 2010 1:51 pm

Hmm, try adding each of these lines to your Config.prc file:

Code: Select all: glx-get-proc-address 0 glx-get-os-address 0 gl-support-fbo 0 glx-support-fbconfig 0 glx-support-pbuffer 0

These each disable some feature or another of OpenGL/X11, which might or might not cause problems on some systems.

If that works, then try them one at a time to isolate the variable(s) that let you get in.

thanks. now something really weired is happening. if i set notify-level to warning, i get a segfault

Code: Select all: Known pipe types: glxGraphicsPipe (all display modules loaded.) :display:gsg:glgsg(warning): glPointParameterfv advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): glDrawRangeElements advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): 3-D textures advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): Compressed textures advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): Multitexture advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): Buffers advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): Occlusion queries advertised as supported by OpenGL runtime, but could not get pointers to extension functions. :display:gsg:glgsg(warning): BlendEquation advertised as supported by OpenGL runtime, but could not get pointers to extension function. :display:gsg:glgsg(warning): BlendColor advertised as supported by OpenGL runtime, but could not get pointers to extension function. :display:glxdisplay(error): Driver claims to support GLX_SGI_swap_control extension, but does not define all functions. Segmentation fault

but if i set notify-level to debug and add "glx-get-{os,proc}-address to 0" the code runs even though the tutorial scene is missing some textures (the panda in the jungle scene)

by **drwr** » Sun Sep 12, 2010 3:30 pm

So, I don't know why the textures are missing--that might be something unrelated--but the glx-get-{os,proc}-address variables control the way that OpenGL extension functions are queried from your OpenGL library. So maybe there is something wrong with the way your OpenGL library is providing these extension functions. Can you enable either one of these variables safely?

I don't understand why you get a segfault with notify-level set to warning, but not debug. Can you show me the stack trace of the segfault in gdb?

Hmm, hard to see how that could be related to the notify-level. Could it be just random, and it only appears to be related?

by **nurbs999** » Sun Sep 12, 2010 4:41 pm

well, could be, but whenever i change this panda throws the segfault.
one other thing, how do get rid of this error:

Code: Select all: display:glxdisplay(error): Driver claims to support GLX_SGI_swap_control extension, but does not define all functions.

by **nurbs999** » Sun Sep 12, 2010 7:36 pm

just reinstalled panda with lastest cvs version and i get a different error. but still only if notify-level is not "spam" or "debug"

which means "1280 GL_INVALID_ENUM"

by **drwr** » Sun Sep 12, 2010 8:57 pm

one other thing, how do get rid of this error:

That error message is a side-effect of setting both glx-get-{os,proc}-address to 0. Panda needs at least one of these enabled in order to get a pointer to the needed OpenGL extension functions. Without either of them, it will have to disable certain OpenGL extensions (most of which probably won't have a dramatic effect on your code, other than the error message). You could also simply squelch the error message with:

Code: Select all: notify-level-glgsg error

But I think we still haven't isolated the fundamental problem yet. The stack trace you posted shows the crash happening within your OpenGL driver, which has nothing to do with the notify-level setting, so it's not clear to me how making this change has anything to do with the crash, other than by possibly changing the application timing. For instance, maybe having "notify-level debug" slows down the application enough to avoid some race-condition type crash in the driver.

David

by **nurbs999** » Mon Sep 13, 2010 6:52 am

since this is an intel gpu with latest intel driver i maybe should report the bracktrace to the intel developer?

by **drwr** » Mon Sep 13, 2010 5:21 pm

I doubt this will be enough information for them to go on. We need to isolate precisely what sequence of calls leads to the crash. It appears to be a subtle combination of Panda3D calls and timing, so it will be a difficult problem to track down from either end.

by **nurbs999** » Tue Sep 14, 2010 6:14 pm

ok, so whats next?

by **drwr** » Tue Sep 14, 2010 9:41 pm

Someone with your graphics card and drivers, a copy of gcc and gdb, and a lot of patience, will need to sit down with the Panda3D code, and do some hardcore investigation. This means getting to know both the Panda3D code and the OpenGL API well, and trying to modify the existing code to use different pathways to determine which pathways are stable and which are unstable.

I've been getting the same behavior in the same old 32-bit Gentoo with a Radeon Mobility 7000 and open drivers. I tried Panda3d from CVS and it appears pretty much the same... I can get it to run (slowly) by increasing the notify-level to either debug or spam and then adding

Code: Select all: glx-support-fbconfig 0

as suggested-- that's the one that did the trick.

When I remove it, I get something probably useless...

Code: Select all: --huge snip-- :display:glxdisplay(debug): supports_swap_control = 1 :display:glxdisplay(debug): supports_fbconfig = 1 :display:glxdisplay(debug): supports_pbuffer = 0 sgix = 1 :display:glxdisplay: No suitable FBConfig contexts available. :display:x11display(debug): Raw mice not requested.

() Backtrace stopped: previous frame inner to this frame (corrupt stack?) (gdb)

I'm off to get those symbols back. Oh, and apparently now using tinydisplay works without these tweaks-- when I first started it was crashing no matter what but I kept updating from CVS and of course updating Gentoo... fun fun.

I switched CFLAGS and recompiled mesa, libdrm, and python without stripping. Now all's a bit different... this is of course with only the notify level at debug so it will crash.

Anything else a noob can do?

I remain baffled. The crash appears to be happening deep within your OpenGL driver, so there's little for me to go on here.

I downgraded mesa from 7.8.2 to 7.7.1 and panda walks again with no tweaks. I'll just leave it there for now, and file a bug with Gentoo.

by **nurbs999** » Fri Oct 22, 2010 7:47 pm

thx for your replies, dropdeadsed.
downgrading mesa-libs worked for me, too.
could you send me a link for your gentoo bugreport, please?

by **Phifo** » Sat Oct 30, 2010 2:08 am

I have the same problem.

Code: Select all: Known pipe types: glxGraphicsPipe (all display modules loaded.) Segmentation fault

I can't run the first manual example.

I downgrade mesa-libs (but i'm using archlinux not gentoo), but doesn't help me

Any ideas?

try to set your notify level to debug. that slows down the panda boot and may help.
and could you please give us more info about our system?
kernel-version, mesa-lib version, graphics drivers and version. and which panda version are your running?

I guess it's because you built without JPEG support
[code]--no-jpeg[code]

Just for the record: in most, if not all, cases 'makepanda.py --everything' is all you need. It will detect missing libraries by itself and append all the --no-* parameters respectively.

Back to the problem. Having the same on my notebook (Archlinux x86_64, Intel Graphics chip).
I'll try to downgrade the mesa lib and let you know what happens. (Given i success in downgrading, which is a problem on arch..)

Blindly isolated the problem to this code:

Code: Select all: if (!_supports_fbconfig) { // We have a good OpenGL context, but it doesn't support the // FBConfig interface, so we'll stop there. if (glxdisplay_cat.is_debug()) { glxdisplay_cat.debug() <<" No FBConfig supported; using XVisual only.\n"; glxdisplay_cat.debug() << _fbprops << "\n"; _context = _temp_context; _temp_context = (GLXContext)NULL; // By convention, every indirect XVisual that can render to a // window can also render to a GLXPixmap. Direct visuals we're // not as sure about. _context_has_pixmap = !glXIsDirect(_display, _context); // Pbuffers aren't supported at all with the XVisual interface. _context_has_pbuffer = false; }

So the context never gets initialised if there is no FBConfig support and if notify-level-glxdisplay is not debug. Will check in a fix, but I do wonder why _supports_fbconfig would be false in the case of Mesa.
So this may just be only a part of the problem.

I think that the whole temp_context hack just doesn't work for many drivers- I have a hunch that it is causing the fact that these extensions (including the FBConfig one) are being queried incorrectly.
