THt's the GL extension provides by gl4es. I was more interested in the underlying GLES extension.

To easily have then, you can add

Code: Select all

printf("LIBGL: GLES extensions are\n%s\n", Exts);

Line 101 of src/glx/hardext.c

(I'll probably do a LIBGL_XXXX option in the near future for that).

I don't really understand what's going on here.

What I see is that:
1. It's not a GLES driver but a full OpenGL driver?
2. It's MESA GL in Software mode (so it's super slow)

Even it does work eventually, it will be to slow to be useable.

PS: Are you using the Beta Desktop OpenGL driver? If yes, then you should not use gl4es and just use the driver. If it doesn't work, consider using old stable GLES driver + gl4es as a test.

[ptitSeb]

Almost. That's the GLES2 driver infos (and this time, it's hardware accelerated). gl4es use GLESv1 driver, but it should be there too.

Doesn't Zandronum work with gl4es and the Broadcom GLES driver?

[raysaaron]

I navigated to /opt/vc/lib/ and i am seeing that libGLESv1_CM.so is just a link to libGLESv2.so

[raysaaron]

I've also found that gl4es uses libGLESv1_CM.so rather than libGLESv1.so

[ptitSeb]

Yes, on the rasperry GLESv1 is named libGLESv1_CM.so.
It can also be found as libGLES_CM.so on other machine.
gl4es has code to load it with this 2 names, and also initialize first the BCM stuff (only found on RPi) if found.

I don't understand what is the status on Zandronum / gl4es for you. Is it working (is it smooth), not working (what is happening).

[raysaaron]

it is not even starting yet.just freezes on the gl4es boot

[ptitSeb]

Freeze? That's odd.

Can you copy/paste the console output?

Also, you can try to use some gl4es env. variable to tweak thing.
You can try LIBGL_FB=1 or LIBGL_FB=3 to see if it solve the freeze issue (LIBGL_FB=3 may slow things down a bit, and LIBGL_FB=1 will skip X11 stuff and so force fullscreen).

[Vanfanel]

@ptitSeb: How's LIBGL_FB=1 supposed to work on the Raspberry Pi? The Raspberry Pi currently uses dispmanx as it's X11-less 2D system, but there is no dispmanx code in gl4es at all.

Mmmm, maybe it will not work indeed.
I don't have a RPi to test, but yeah, some dispmanx minimum code probably need to be written for LIBGL_FB=1 to work.

[Vanfanel]

@ptitSeb: It does not work at all, I have tried
Any chances of dispmanx being added? X11 isn't exactly a good thing on the Pi and all gaming-oriented distros skip it for good...

I'll take a look and see if I can put some simple init code.

Ok, I have pushed a first try to my github.
I try to use dispmanx complety dynamicaly (so there is still no #ifdef BCM_HOST to keep the binary kindof universal). Not sure it works, so if you can give it a try. It should create a dispmanx display (the size of the screen) when using LIBGL_FB=1

Nope, still the same problem:

Mmmm, ok, third try, this time it should compile on the RPi.

[raysaaron]

I don't know but it works on Eric Anholt's OpenGL Driver.

[ptitSeb]

I don't know but it works on Eric Anholt's OpenGL Driver.

Zandronum works with the beta OpenGL driver?

[Vanfanel]

@ptitSeb: now it builds!
What should I use to try it? I tried building SDL2 with OpenGL support, but none of the tests I tried work.

[ptitSeb]

Simply glxgears to check it works.

From the build folder of gl4es, try with

Code: Select all

LD_LIBRARY_PATH=lib glxgears

and also with

Code: Select all

LD_LIBRARY_PATH=lib LIBGL_FB=1 glxgears

to see fullscreen stuff.

a test with

Code: Select all

LD_LIBRARY_PATH=lib LIBGL_FB=3 glxgears

can be interesting also.

[Vanfanel]

@ptibSeb: GLXGears depends on X11 libs, which are not present on my system, and never will.
Any other example I can build without depending on stinky X, please?

[ptitSeb]

Anything based on SDL / SDL2 then. You'll need to compile SDL(2) with OpenGL support if needed.

Zandronum should work.

Stunt car remake on my github is simple enough and should work (based on SDL) : https://github.com/ptitSeb/stuntcarremake
You can also try Prototype: https://github.com/ptitSeb/prototype that should works too.
