SDL2 + OpelGL ES2 + Freescale i.MX6

romain · November 7, 2013, 12:42pm

Hi all,

I experience somme difficulties to match the good driver and to have a working application.
My application is based on SDL2 and works fine on my computer.
I have compiled :

SDL 2.0.1
SDL image 2.0.0
SDL ttf 2.0.12 (and freetype 2.5.0.1 needed by SDL ttf)

On the embedded platform called Utilite (http://utilite-computer.com/web/utilite-standard-specifications), I get this output from my software :

Num Drivers: 4
Found Driver: opengl
-> ACCELERATED
-> PRESENTVSYNC
-> TARGETTEXTURE
Found Driver: opengles2
-> ACCELERATED
-> PRESENTVSYNC
-> TARGETTEXTURE
Found Driver: opengles
-> ACCELERATED
-> PRESENTVSYNC
Found Driver: software
-> SOFTWARE
-> TARGETTEXTURE
With those errors :

SDL ERROR:No available video device
SDL WINDOW:No available video device
SDL RENDERER:Invalid window
It seems that I have to choose one of the available drivers. But how ? AFAIK I should want to use Open GL ES2. What do you think ?

I found this command :

export SDL_VIDEODRIVER=dummy

And now I have this error :

SDL RENDERER:Couldn’t find matching render driver

When compiling SDL2 I have choosen to configure with --disable-video-x11 to force the use of an accelerated driver. I don’t remember the behaviour with a standard configure/make/make install; I check it now.

Trying to compile SDL2 with ./configure and make, it ends with errors :

Can an admin correct the mistake “OpelGL ES2” in “GLES2” please ? [Laughing]

Gabriel_Jacobo · November 7, 2013, 10:05pm

It may be that you found a bug, please fill one in Bugzilla and attach your
config.log and SDL_config.h files. Thanks!

Done. https://bugzilla.libsdl.org/show_bug.cgi?id=2226

Back to what brought me here, how can I choose the “driver” to use to render my software ? [Rolling Eyes]

Thanks

Aggelos_Kolaitis · November 11, 2013, 6:56pm

Use the hint SDL_HINT_RENDER_DRIVER

Thanks neoaggelos.

I’ve added
Code:
SDL_SetHint(SDL_HINT_RENDER_DRIVER, “opengles2”);

before
Code:
SDL_Init(SDL_INIT_VIDEO);
SDL_CreateWindow(“Screen”,0,0,SCREENWIDTH,SCREENHEIGHT,SDL_WINDOW_BORDERLESS);
SDL_CreateRenderer(SCREEN,-1,SDL_RENDERER_ACCELERATED|SDL_RENDERER_PRESENTVSYNC);

SDL_SetHint() gives no error, but it didn’t change the output of the 3 others :

SDL INIT_VIDEO ERROR:No available video device
SDL WINDOW:No available video device
SDL RENDERER:Invalid window

If I use this command (the only one working, I tried x11 for example, but it’s not recognized) :

export SDL_VIDEODRIVER=dummy
Then I get the output :
SDL RENDERER:Couldn’t find matching render driver
Which I think is better…

When I compiled SDL I could see in the configure log :

checking for OpenGL (GLX) support… yes
checking for EGL support… no
checking for OpenGL ES v1 headers… yes
checking for OpenGL ES v2 headers… yes

And I was wondering : is EGL mandatory for GLES2 ? That could explain why the render driver cannot be used…

Depends on the platform, but most likely yes.

Ok, this also explains why I couldn’t compile the GLES2 mesa demos (es2gears, glmark2-es2)…

I tried to install some libs, and got errors :

Looking at this:

It seems that gpu-viv-bin-mx6q ought to provide everything you need. What
do you get from: dpkg -S egl.h–

Can you post your configure line and config.log ?

Hi all, the last post didn’t reach the mailing list because of it’s length. You can read it here : http://forums.libsdl.org/viewtopic.php?t=9713#40613

Configure call :

$ ./configure --enable-gles2 --enable-egl

And the config.log in a nutshell :> configure:16611: checking for EGL

configure:16618: $PKG_CONFIG --exists --print-errors "egl"
Package egl was not found in the pkg-config search path.
Perhaps you should add the directory containing `egl.pc’
to the PKG_CONFIG_PATH environment variable
No package ‘egl’ found

romain · November 15, 2013, 8:49pm

It seems that some guys have successfully run (compiled?) es2_info on Utilite.
I tried to compile mesa demos (es2gears, es2_info, …) on the Utilite but the configure cannot find neither EGL or GLES2… Those headers should be included in the Vivante drivers… How can I verify that ?

romain · November 19, 2013, 1:25pm

4 days later and still trying to find a solution.

I found that bug reported in 09/2013 related to the lack of OpenGL headers in the Vivante drivers : https://bugzilla.yoctoproject.org/show_bug.cgi?id=5098
Is EGL part of OpenGL ?
And do I need EGL to have a working SDL and to run my OpenGL/GLES2 - based application ?

Thanks

EGL is a system designed to support OpenGL (it’s the middle man between the
hardware and system specific implementations and the OpenGL API). Whether
you need EGL or not depends on the platform you want to run on, but most
likely, yes, you need it.

From your earlier messages, it seemed like the configure script couldn’t
find egl.pc, the package config specification for EGL.

What’s the full output of dpkg -S gpu-viv-bin-mx6q ?

2013/11/19 romain > 4 days later and still trying to find a solution.

I found that bug reported in 09/2013 related to the lack of OpenGL headers

Here is the full output :

$ dpkg -S gpu-viv-bin-mx6q
gpu-viv-bin-mx6q: /usr/share/doc/gpu-viv-bin-mx6q/changelog.gz
gpu-viv-bin-mx6q: /usr/share/doc/gpu-viv-bin-mx6q

Apparently the Vivante GC2000 GPU supports both OpenGL and GLES2, so SDL should be able to handle both, isn’t it ?
I’m also playing with environment variables, but the manual isn’t rich in what I should put in them (I tested with dummy/x11/opengl/software…)

I’m sorry, I pasted the wrong command

Try: dpkg-query -L gpu-viv-bin-mx6q

It seems there’s no egl.pc, so the problem comes down to a buggy package,
but maybe you can work around it. Try sticking these files in
/usr/lib/pkgconfig :
https://github.com/Freescale/meta-fsl-arm/tree/master/recipes-graphics/gpu-viv-bin-mx6q/gpu-viv-bin-mx6q

You may need to play around with your system to find the solution that
works for you, it’s not something that can be fixed from the SDL side.
