Problems with 2 examples on linux

Malakh · Post by **Malakh** » Mon Sep 29, 2003 8:36 pm

All the examples are compiling for me but exmaples 2 and 7 do not apear to work correctly. The scene textures appear to be all white. Is there something I can do to resolve this?

Are you using version 0.4? Maybe it is better with version 0.4.1

I ve the same problem, looks like as if the engine doesn't find the textures (Error messages on the console, telling "Warning couldnt' load texture ....").
Each wall is white, and i don't see any textured skybox.

The strange thing is that the example1 works well, whereas the mesh has a texture.

I use the latest irrlicht (0.4). and Mandrake 9.0 (gcc 3).

Sorry,

I haven't tested with 4.1...

I'm so stupid ....

I had the same problem with 0.4. With 0.41, the textures are ok. But now there is another problem: It is very dark in the rooms - not as bright as on the screenshots. And in example 7, I hava some strange light effects. It looks as if a red sun would shine through the wall, and sometime there are red triangles on the wall.

I've tested with the 0.4.1.

I now see textures on the walls, but console prints some warnings.

Here is a copy/paste of the console :

-----

I've checked the path, it's OK.

The FPS is VERY low (1 FPS). Under windows the fps is higher (about 200).

Like zoschfrosch,the map is dark, it's as if only ambiant light was activated.

I've just installed the latest drivers from nvidia.)

"Warning: This driver is not available in Linux. Trying OpenGL."
I guess this only means that there is no DirectX available an that instead OpenGL is used. So it doesn't matter.
"Warning: Could not find texture in Q3 .bsp:textures/common/caulk"
If you look into the Quake-File (it is a zip file, you can open it with arc), you will see that these textures are really not there. I guess these are textures which are not used in the scene, but they are referenced in the model file. You can avoid this warnings if you unzip the file, create the missing directories and files (take any jpeg-Files) an zip the file again. But it does not change anything in the behavior of the example.

I have a fps between 20 and 30, but my machine seems to be slower than yours because the OctTree needs 206ms to be created. Maybe the software renderer is used instead of OpenGL on your installation?

I think you're right : Linux uses Soft render instead of OpenGL... but as a linux newbie, i don't know how to change it...

What must i do ?
Why my video drivers installation didn't changed that ?

thanks for your replies.

I can tell you what I had to do to get it work with debian linux. I hava a nvidia tnt2 card, and unfortunately, there comes no driver for it with debian. So I had to use the original driver from nvidia, recompile the kernel etc. After that, I had to add some things in the XF86Config-File. Then OpenGL worked.
Because I don't know mandrake, I can only suggest where the problem is. I made a search with www.metager.de for "mandrake" and "opengl" and found the following intersting link: http://www.libsdl.org/pipermail/sdl/200 ... 37257.html .
I guess you installed the video driver without OpenGL. Run glxinfo in a shell to see if it is on your machine. If not, maybe you find help on the mandrake site or on the site of you graphics card manufacturer.
Some distri's like Suse linux are very easy to configure because they have a Gui-Tool for that. Perhaps, Mandrake has such a tool, but I don't know.
Maybe it would be interesting to compare the output of glxinfo on your machine with mine. In my output, I can see that the OpenGL version is from nvidia:
...
"OpenGL version string: 1.3.1 NVIDIA 31.23
...
Good luck

Thank you for your reply !

The glxinfo tells :

"OpenGL version string: 1.2 Mesa 3.4.2"

It seems you're right, Nvidia drivers are not used for OpenGL.

I'll try to fix it.

Thank you again !

just found some useful info here
http://dri.sourceforge.net/cgi-bin/moin ... leshooting

in my case (voodoo3) i had the tdfx driver loaded, changed X to run with 16 bit colors (this is a voodoo3 specific limitation) and still no success, glxinfo kept telling me "direct rendering: No"

in the XFree86 logfile there was no indication as to what could be wrong. but with
setenv LIBGL_DEBUG verbose

glxinfo told me it did not find some shared library, which belonged to the debian package libglide3. so i had enabled my card everywhere, but not installed the actual drivers needed :-/

maybe the link to the dri project should go into the irrlicht documentation to help people configuring their linux for OpenGL. i used my installation for years and did not even realize i'm not using hardware accel...
