Can not execute basic example, showing vertex shader compilation failed #45

Closed sk-Prime closed 2 years ago

sk-Prime commented 2 years ago

I tried the basic example provided on boxy readme page. It compiles but i can not execute because of some runtime error.

Error

/home/sk/.nimble/pkgs/boxy-0.4.0/boxy/glsl/410/atlas.vert(1(10): 0:1(10): error: GLSL 4.10 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, 3.00 ES, and 3.10 ES

I think there is something to do with glsl version. Do you know how to fix it. Thanks in advance.

Other info

OS: Linux mint 20.3 64bit Nim compiler: 1.6.2 Boxy installed using nimble. However windy example on github readme runs perfectly.

Hey, this looks like a linux mobile device that only does OpenGL 3.10 ES - ES stands for mobile.

Sorry currently we don't support mobile linux devices.

If this is a desktop or laptop some thing is wrong with your OpenGL setup.

Not a mobile device but a laptop with embedded Intel hd graphics. Here is some more info, if it is helpful. In OpenGL core profile version string it says 4.5 (core profile) 

sk@sk-pc:~$ glxinfo | grep OpenGL
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) HD Graphics 4400 (HSW GT2)
OpenGL core profile version string: 4.5 (Core Profile) Mesa 21.2.6

OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile

Its strange it says it supports openGL 4.5 which is enough for us.

OpenGL core profile version string: 4.5

But it does not load it. I think it some thing that can be fixed in windy: https://github.com/treeform/windy/blob/master/src/windy/platforms/linux/x11.nim#L572-L686

I am not sure how, as I don't have both openGL ES and openGL desktop GPUs at the same time.

Yes, the issue is about windy not boxy. Most of examples provided in windy run properly but the triangle.nim shows same issue with some more information. I will make a issue at windy repo.

Thank you. If you can figure it how to select the right openGL version we would take it.
