SDL_SetVideoMode failed (Couldnt find matching GLX visual)

Post by sentinal »

Hi all,

This is a poor effort for a first post, since it looks like a pretty basic system configuration error at my end ... and Im stuck on how to fix it. Any advice appreciated.

Situation:
New machine, Linux (PCLinuxOS 2010, 32bit, Nvidia 8400GS with 195.36.15 drivers - all up to date).

All the build tools are the latest stable versions (automake 1.11, autoconf 2.65, gcc 4.4.1, etc)

The first thing I did on this new machine was run warzone, since that is all this machine will be used for. The old warzone from the PCLinuxOS repository works OK (that is Version 2.0.10, built Jan 26 2008), so the basics are all good at first glance.

Downloaded the source for Version TRUNK r10453, and got that compiled eventually. Only other things I had to do to get it working was download and build quesoglc to get a working GLC library. I did have to manually modify the Makefile that ./configure generated though to include -lfontconfig to get around some undefined symbols that quesoglc was looking for. That should not affect anything to do with OpenGL though.

When I run the new build of trunk, it falls over quite early with :
3d |07:47:58: [screenInitialise] Using Video mode 640x480@32bpp flags = 0x90000002 **
error |07:47:58: [screenInitialise] Error: SDL_SetVideoMode failed (Couldn't find matching GLX visual).

** I added this debug line to the code to see whats going on. The SDL flags equates to :
SDL_OPENGL | SDL_ANYFORMAT | SDL_FULLSCREEN, which looks fine.

So SDL_SetVideoMode should be looking for a visual with OpenGL, no FSAA, fullscreen, with RGBA 8,8,8,8 and a depth of 16.

My glxinfo shows a lot information, but Im stumped seeing a problem.

direct rendering is ON, GLX version is 1.4, and VBO extension is present.

There are plenty of available visuals with RGBA = 8,8,8,8 and a depth of 24 .. so I would have thought that SDL could find something appropriate in that.

There are no visuals listed with a specific depth of 16 .. but that should not matter ? I have tried doing a quick hack in lib/ivis_opengl/screen.c to make it look for depth 24, but that made no difference.

glxinfo dump follows :

Finally, xorg.conf is untouched from the installation, nvidia drivers are in use, and
Option "AddARGBGLXVisuals"
is defined as the only option.
Default depth = 24

Not sure what the next step should be ? Should be something trivial .. any ideas ?

Oh - I have also downloaded and tried out some other SDL / OpenGL apps that are pre-compiled from the repository, and no issues there. Even installed wine and tried some win32 games - IL2 sturmovik for example comes up and works well enough.

The only thing I can think of at this stage is that Im running KDE 4 on this box, and it probably has some compositing features turned on. I do have laptop floating around the bedroom somewhere that is used purely as a DJ box, and that runs mixxx - which uses an OpenGL context to draw the waveforms for the songs playing ... and I do remember that it was pain getting that running smoothly whilst compiz was running on the same machine, and took a lot of hacking to get it working.

Thanks guys, I cant wait to get my teeth into the newer version. You guys have done an incredible job breathing new life into this fantastic old game, and Im truly staggered seeing some of the work you have done.

Re: SDL_SetVideoMode failed (Couldnt find matching GLX visua

Post by cybersphinx »

Try the --resolution=WIDTHxHEIGHT parameter, with your normal screen resolution. Though the 16 bit is strange, it should use 32/24 by default....

Re: SDL_SetVideoMode failed (Couldnt find matching GLX visua

warzone2100 --debug=all --resolution=1440x900

Same results.

Also - when I was referring to a 'depth' of 16, that is the value in lib/ivis_opengl/screen.c that gets assigned to
SDL_GL_DEPTH_SIZE when the bpp / bitDepth is either 32 or 24. I believe that's the minimum size requirement of the Z-buffer.

Il try some more debugging - had a good sleep last night, and that makes all the difference sometimes ;)

Re: SDL_SetVideoMode failed (Couldnt find matching GLX visua

Post by sentinal »

Good question.

In the code (lib/ivis_opengl/screen.c), that is the first place where LOG_3D gets output, and it happens after the call to SDL_SetVideoMode().

If I put a copy of the LOG_3D output before the call to SDL_SetVideoMode(), then the whole output is blank. None of the things have valid values until after this call it seems.

I have a little test program that just creates a simple SDL OpenGL context, displays an image and then quits. This works fine .. code below :

Code: Select all

int main(int argc, char *argv[])
{
    if ( SDL_Init(SDL_INIT_VIDEO | SDL_INIT_TIMER) != 0 ) {
        printf("Unable to initialize SDL: %s\n", SDL_GetError());
        return 1;
    }

   /* check video info - run this under gdb, and check the contents of video_info, it looks exactly the same as when     warzone gets the video_info */
    const SDL_VideoInfo *video_info = SDL_GetVideoInfo();  
    
    SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 ); 
    SDL_WM_SetCaption("My Little SDL-OpenGL Test Application", NULL);
    screen = SDL_SetVideoMode( 1440, 900, 32, SDL_OPENGL | SDL_FULLSCREEN ); // hard coded values
    if ( !screen ) {
                printf("Epic Fail - Unable to set video mode: %s\n", SDL_GetError());
                return 1;
        }

        {
                printf("OpenGL Vendor : %s\n", glGetString(GL_VENDOR));
                printf("OpenGL Renderer : %s\n", glGetString(GL_RENDERER));
                printf("OpenGL Version : %s\n", glGetString(GL_VERSION));
                printf("OpenGL GLSL Version : %s\n", glGetString(GL_SHADING_LANGUAGE_VERSION));
                printf("Video Mode %d x %d (%d bpp)\n", 1440, 900, 32);
                /* Dump information about OpenGL implementation to the console */
                printf("OpenGL Vendor : %s\n", glGetString(GL_VENDOR));
                printf("OpenGL Renderer : %s\n", glGetString(GL_RENDERER));
                printf("OpenGL Version : %s\n", glGetString(GL_VERSION));
                printf("OpenGL Extensions : %s\n", glGetString(GL_EXTENSIONS)); // FIXME This is too much for MAX_LEN_LOG_LINE
                printf("  * OpenGL GLSL Version : %s\n", glGetString(GL_SHADING_LANGUAGE_VERSION));
        }

   /* -------
      do more stuff after the video mode is set - create a surface, display an image, wait around and then quit
  */
}
This has the same queries as the 3D logging in warzone. If I put the block of debug output before SDL_SetVideoMode, it is all blank - just like my warzone test, if I put it after a successful call to SDL_SetVideoMode, I get this output :

There is something extra happening in my warzone2100 binary compared to my little simple test binary.

As an idea, I put a hack in warzone2100 main.c, to go ahead and try and jump into SDL_SetVideoMode before it does anything else at all - same result - fails to find a GLX mode to use.

This suggests it may be a link-time problem more than anything else. My simple test program only links against -lSDL -lGL, whereas with warzone, many other libs are being linked in including -lGLC -lfontconfig -lGLU -lX11. Ill play with that idea and see if something comes up.

I might try rebuilding QuesoGLC next.

Another test :
- I downloaded the source for 2.2.4 stable, and built that, rather than the TRUNK version from svn. Same result. There are a few extra little video_mode flags being set with 2.2.4 compared to TRUNK, but the results are the same.

Since my simple SDL-OpenGL test works as expected, Im discounting the problem being something to do with compositing / KDE4. I have compositing turned off at the moment too.

Dont know if this helps, but here is a bit of trace from running it under gdb :

Code: Select all

Breakpoint 1, screenInitialise (width=640, height=480, bitDepth=32, fullScreen=1, vsync=1) at screen.c:79
79              int bpp = 0, value;

82              screenWidth = width;

Re: SDL_SetVideoMode failed (Couldnt find matching GLX visua

Post by sentinal »

Note from the gdb trace that video_info has :

hw_available = 0, so no hardware surfaces available !!
no hardware blitter available !!!!
and video_mem = 0, although this flag is not reliable according to the SDL documentation.

The video format (vfmt) portion of the video_info looks OK

interesting.

Can you try ldd on warzone and on your test binary? Maybe there's a wrong libGL somewhere...

Oh ... I think you nailed it.

Will report back with more info shortly, but basically, test app is linking to nvidia-current specific GL libs, whereas warzone is linking to some horrible generic thing in /usr/lib/libGL.so.1

Give us a minute, Ill sort this one out and post details for how to diagnose this fault, and correct it.

OK guys, runtime lib paths it is.

Situation
=======
- The system I am running on has a generic OpenGL library installed (probably Mesa3D), as well as the proprietary Nvidia GL libs that come with the Nvidia driver.
- The system is setup such that the Nvidia GL libs are preferred over the generic GL libs. Any normal program at runtime will link to the Nvidia lib.
- When warzone is configured and built, by default, configure slips in an option to the linker to tell the executable to look for libs in /usr/lib in preference to any other libs. As a result, a simple ./configure && make on a system with both libraries installed will end up pointing to the wrong library.

How to diagnose
============
- If you are having problems getting openGL to work at all, try this test to determine if you are affected or not :

Code: Select all

$ locate -i libgl.so
...
this will display (possibly) a number of files called libGL.so
/usr/lib/libGL.so      <----- generic, Mesa3D library, you dont want this
/usr/lib/nvidia-current/libGL.so.195.36.15    <----- thats the one you want. Notice the version number = the nvidia driver version

$ ldd warzone2100 | grep libGL.so
..
Displays exactly which libGL.so that your binary will be looking for.  
If its /usr/lib/libGL.so, then thats what your problem is
How to Fix
=========
If you compile warzone again, you will notice (if you look real hard), that when the binary is linked, there is a compiler option amongst all the other options that is causing this situation :
-Wl,-rpath,/usr/lib

This tells gcc to tell the linker (ld), to hard-code the path /usr/lib into the binary as the place where the binary should look for its dynamic libs in preference to any others.

There is an option during the configure phase to disable this. So, just reconfigure, rebuild, and Bob's your Uncle :

Code: Select all

$ ./configure --disable-rpath
$ make
All sorted :)

Now I can start playing the new version :):):):)

Beware of blanket statements. For me, that *is* the nVidia OpenGL lib. I notice that if you download and run the installer from nVidia, it spends some time looking for evil OpenGL libs and such. No idea what the various Linux package managers are doing.

And congrats on chasing the problem down. Nice work!

Was going to make some basic tests on low end hardware. Using lightweight ubuntu on armv7 core.
Followed steps to install 3.1.2 from downloaded tar, installed required dependant packages then compiled.
Had to use either libglew1.7-dev or libglew1.6-dev, no option for libglew-dev from compile guide.

Code: Select all

sudo apt-get install --yes build-essential automake xz-utils g++ libqt4-dev libsdl-dev libtheora-dev libfribidi-dev libopenal-dev libvorbis-dev libxrandr-dev libfontconfig-dev wget cmake wkhtmltopdf libglew1.7-dev libphysfs-dev

up to date on packages as well. What should I try to fix this?

ubuntu@PC-test:/home/test/warzone2100-3.1.2$ ./autogen.sh && ./configure --disable-rpath && make
makes no difference...

Ok thanks, that gave me a thought. I'll have to get an SD card reader, burn a more up to date OS onto it and install it to the said device. Straight upgrade doesn't appear feasible in this case...
