AllegroGL (or OpenGL?) set_gfx_mode crash. Hardware problem?

anto80

Hello all.

- I have a problem running a piece of code (Allegro+AllegroGL) on a computer although it run perfectly on another one.
- I use MSVC6 with these 2 machines.
- Allegro and AllegroGL have been compiled successfully (for MSVC6) on these 2 machines, (and I used to same method to do it).

I use the "DEBUGMODE=1" version of allegro and AGL on these 2 machines. So i can use the debugger to see where exactly it crashs, and it crashs on set_gfx_mode() call.

The allegro.log shows 42 pixel formats : all failed. Finally the message is:
* ERROR * select_pixel_format(): Didn't find any available pixel formats!

I am using 32 bpp color depth, and windowed mode on the 2 machines.
- The machine that run perfectly got an ATI Radeon graphic card (Win XP SP2).
- The machine that crashs perfectly got a graphic card integrated on the motherboard, named "Intel(R) 82845G/GL Chip" with 64MB (on Win XP SP1). Please note that i have no problem running Unreal Tournament on this one (in 800*600).

What can i do? (instead of buying another graphic card...)

The code is below. (I am not showing you the part of the code AFTER the crash. I know that some things need to be freed or cleaned before exiting...).

Have you tried using 24 as a colour depth instead of 32, to see if you have this mode?

anto80

I tried

nColDepth = 24;
and
nColDepth = 16;

It crashes the same way with the same message in allegro.log.

Richard Phipps

Can you run any openlayer programs in fullscreen? If you can then it is possible..

anto80

No the demo.exe from OpenLayer2.0 crashs as well.
here is the openlayer.log

OpenLayer started up succesfully

Have you got the latest OpenGL drivers? Sounds like it's either your gfx card not supporting this or your drivers.

Just to check: Your OS is not running in a 16 bit screenmode is it?

GullRaDriel

Add this in your code please and show us the output:

printf("Graphics Driver: OpenGL %s (%s)\n"
       "  %s detected\n"
       "  Set %dx%d %dbpp %s mode\n",
       glGetString(GL_VERSION), glGetString(GL_VENDOR),
       glGetString(GL_RENDERER),
       SCREEN_W, SCREEN_H, bitmap_color_depth(screen),
       (gfx_driver->windowed ? "windowed" : "fullscreen"));

NB: This code was provided by Kitty Cat in an old similar thread I made. The problem was the driver.

I don't know. There's a "OpenGL" tab the advanced properties of my card display settings.
here are the options (i hope the translation from French is correct)

async toggle     : NO      (can choose Y/N)
Triple buffering : Default (can choose "Yes", "No", or "Default")
toggle strategy  : Toggle  (can choose "blit")
Buffer depth bits: Default (can choose 16 or 24)
Force texture S3TC Compression: NO (can choose Y/N)
Force texture FXT1 Compression: NO (can choose Y/N)
Driver memory space: Normal (can choose Low,Normal,High)
Texture palette  : Desktop palette (can choose 16bits per texel, 32bpt)
anisotrope filtering : Application control (can choose "App control", "Yes", "No")

My desktop is 32 bpp.

You mean i have to update my graphic gard driver?? But i didn't had problem before with any OpenGL-based games like Unreal! I'm confured...

GullRaDriel

Perhaps It is using the Microsoft Driver which is not very famous.
Can you give us the output of the printf(...) I gave you before ?

anto80

I can't.
Even it i do this, it crashs on the glGetString line.

char  szBuf[256];
allegro_init();
install_allegro_gl();
strcpy(szBuf, (char*)glGetString(GL_VERSION));

Crash message:

---------------------------
Microsoft Visual C++
---------------------------
Unhandled exception in testalleg.exe (MSVCRTD.DLL): 0xC0000005: Access Violation.
---------------------------

GullRaDriel

You do not have OpenGl properly installed on your system.

anto80

What can i do?
Do i need to install something "global to OpenGL" ? or will i have to install something specific for my graphic card?

Richard Phipps

Get the latest OpenGL drivers from your gfx card manufactorer.

Kitty Cat

What if you set AGL_RENDERMETHOD to be required? I don't think you can use the glGetString functions without being in an OpenGL mode.

anto80

Ok guys you were right!! After having updated my graphic driver the OpenLayer2.0 demo runs perfectly and my program too.
Thank you very much for your help.

Anyway GullRaDriel's printf still crashs.
[edit] Kitty is right: afted having moved the glGetString(xxx) calls AFTER the OpenGL set_gfx_mode, the printf displays a correct string.
Thanks!

Milan Mimica

It shouldn't crash anyway. Which version of AGL are you using?
