Could not init gl function pointers

[karlb]

Hi!

I"m trying to run the tests, but I get the following error:

karl:~/lwjgl/lwjgl-0.7$ java -cp .:lwjgl_test.jar:lwjgl.jar org.lwjgl.test.opengl.Game
Setting display mode to 640 x 480 x 24 @0Hz
Created display.
Failed to create OpenGL due to java.lang.Exception: Could not init gl function pointers

What am I doing wrong?
(btw: there are ;s instead of :s in the README file. That's wrong, sin't it?)

Thanks,

Try to run your application  with the -ea flag (and be sure to have lwjgl_d in your path). But most likely, the problem is missing OpenGL drivers.

The ; is sort-of-wrong - windows use ; for separating paths, while linux and mac use :.

I'm using the binary ATI drivers under debian woody, and they work fine with other games.

Enabling assertions doesn't give any interesting output (I don't have the exact output, since I'm at another computer right now).

When starting the game my monitor flashes (like it does when changing resolutions), so I guess it finds the libraries. OpenGL is installed normally and liblwjgl(_d)?.so is in the current directory. Adding . to the library path doesn't help, either.

Alien Flux doesn't work also (which isn't very surprising).

Thanks,

Ok, I just added more verbose debug output. And you're right, it looks like it can find the OGL library, but it simply fails to load some (needed) symbols. Here you go (use with -ea):

It really can't find some symbols. Here's the output:

I'll see whether I can find some more recent drivers. It's strange that my current drivers don't support these features (and that no other game required these).

Thanks,

From where I'm standing, it looks like the driver is lying about it's version and some extensions. LWJGL tries to load GL 1.3 features but fails. What's the output from glxinfo (especially the reported OpenGL version)?

To make LWJGL more robust against those kind of drivers, we could implement it so it merely disables the features instead of failing completely. That is, when the driver reports OpenGL 1.3 but some OGL 1.3 symbols fails to load, LWJGL falls back to OpenGL 1.2 (or whatever succeeds). What do you think?

Here's the glxinfo output:

name of display: :0.0
display: :0  screen: 0
direct rendering: Yes
server glx vendor string: SGI
server glx version string: 1.2
server glx extensions:
   GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
client glx vendor string: SGI
client glx version string: 1.2
client glx extensions:
   GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context,
   GLX_ARB_get_proc_address, GLX_ARB_multisample, GLX_ATI_pixel_format_float,
   GLX_ATI_render_texture
GLX extensions:
   GLX_EXT_visual_info, GLX_EXT_visual_rating, GLX_EXT_import_context
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon 9700 Pentium 4 (SSE2)
OpenGL version string: 1.3 (X4.2.0-3.2.5)
OpenGL extensions:
<snip>
glu version: 1.3
glu extensions:
   GLU_EXT_nurbs_tessellator, GLU_EXT_object_space_tess
<snip>

And here's the output of fglrxinfo, which comes with the driver:

display: :0.0  screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: Radeon 9700 Pentium 4 (SSE2)
OpenGL version string: 1.3 (X4.2.0-3.2.5)

Using the latest drivers doesn't help, so this is probably a problem affacting all Linux/ATI users (well, except those having quite old cards, which are supported by by open-source drivers).

Bye,

Ok, LWJGL now ignores advertised extensions with missing symbols (and dumps a notice on std out). You should be able to use LWJGL even on lying drivers now:

This seems to work.

Thanks!

I'll update the Webstart Alien Flux with it in a moment.

Am I doing something wrong, or is this a bug?

oh sh*t, I forgot to upload the new resources file.
<edit>Right, fixed it. Have another go. 7.5mb of patching to do

It works fine now. Thanks!

btw: is there any reason, why webstart download only at ~2kbyte/s (I have a 8kbyte/s connection)?

My website appears to have been running at very low speed all day. I'll have to investigate.

Alien Flux still crashes, but I get to the main menu this time (that's why I thought it would run...). It crashes when I try to start a game. Here's the log (error log is empty):
