error: GLSL 3.30 is not supported.

[ItalianPlumbo47]

I don't why this is happening. Maybe it has something to do with my Intel card. Maybe it's a bug?

[isage]

Yes, it has something to do with your intel card.
Engine requires GPU with OpenGL 3.3 or later.
We'll adapt it to older GPUs later.

[alexeevdv]

Looks like i have the same error on my notebook.

My video:
Mobile 4 Series Chipset Integrated Graphics Controller
Intel Corporation i945

[isage]

Yep: Version: 2.1 Mesa 10.1.3
And also it reports strange version: Using OpenGL 35347984.0
But don't worry, i have notebook with Intel 945GSE lying around, and i've started to port shaders to 2.1
I'll add support for older GPUs after finishing with lighting (which is almost done)

[alexeevdv]

That would be awesome :)

[ghost]

@zero17333 do you use windows 10? seems like windows 10 has limited support for integrated graphic drivers. some drivers have only have max opengl 1.5 support

[isage]

@trollworkout i'm pretty sure it won't even build on windows.

Intel supports opengl 3 only since Sandy Bridge (6th gen of Intel HD)
Intel GMA, however, is whole another story, being even older than IntelHD, going up to 1.5 on win and 2.1 on linux/osx. And then, there's also PoverVR based GPUs, used in Atom processors, which support 2.1.

Anyways, support for gl 2.1 based cards should be done by the end of week, i hope.
I'm afraid we can't/won't support anything lower 2.1, but i'll try.

[ItalianPlumbo47]

@trollworkout Actually I'm using Antergos Linux with a Haswell i3. It is odd how OpenGL is lower than I thought.

@isage Thank you for your effort

[isage]

@zero17333 can you provide log from console?

[teepean]

It might be fixed in Falltergeist itself. "It's very probably because you don't specifically ask the OpenGL implementation (in this case mesa) for Core Profile because only Haswell OpenGL core profile supports GLSL 3.30, as shown in this Haswell glxinfo dump: "

http://darmawan-salihun.blogspot.fi/2015/03/glsl-330-in-intel-haswell-cpu.html

[isage]

Yep, that's what i thought. Strange, tho, hasswell should support 3.3 on linux.
Anyway, should be fixed in latest master.

[teepean]

Thinking again SDL might be the place to fix the issue.

[isage]

@teepean we specifically ask for core profile. That's why we fall back to 2.1 (in latest master) on anything lower 3.2, because 3.1 is rare, and 3.0 shaders are deprecated in core profile.

[isage]

@zero17333 can you also post output of glxinfo | grep OpenGL

[isage]

Hm, that might be, however sdl/mesa bug. As we dont specify version, only that we want core context, mesa can still choose lowest, meh. I'll see what i can do, but first i need confirmation with info above

[ItalianPlumbo47]

Did someone change something between when I first posted this and now? It seems to working now for some reason after git pull and rebuilding. The first time I tried this it didn't work after doing it 7-8 times.

AFTER the rebuild it worked immediately and I can start the game

[isage]

Yes, as I've said, we added render path for opengl < 3.2, but i still need that glxinfo, because you should get ogl 3.3 on your system

[ItalianPlumbo47]

glxinfo | grep OpenGL [21:06:44]
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 11.1.2

[isage]

Yep, that's definitely mesa-related bug. I'll look into it.

[isage]

@zero17333 could you try adding after https://github.com/falltergeist/falltergeist/blob/master/src/Graphics/Renderer.cpp#L107

SDL_GL_SetAttribute(SDL_GL_CONTEXT_MAJOR_VERSION, 0);
SDL_GL_SetAttribute(SDL_GL_CONTEXT_MINOR_VERSION, 0);

And see, it you'll get 3.3 profile instead of 3.0

[ItalianPlumbo47]

I added those lines between

SDL_GL_SetAttribute(SDL_GL_CONTEXT_PROFILE_MASK, SDL_GL_CONTEXT_PROFILE_CORE);

and

SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);

and I got:

[CRITICAL] Init OpenGL - [FAIL]

It was definitely in Renderer.cpp and it was on lines 108 and 109

[isage]

Yep, i've already tested this myself. Anyway, after #457 is merged you should finally get 3.2 context on mesa.
