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

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) http://img715.imageshack.us/img715/3127/pandafailu.jpg
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?

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:
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.
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.
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 just tried the latest cvs version and my problem even got worse. i get a segfault no matter which notify-level i try

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
glx-support-fbconfig 0
as suggested-- that’s the one that did the trick.
When I remove it, I get something probably useless…

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.
and i get this output
