tetris.v runtime error

[wpeckham]

V version: V 0.1.29 e6e1011

OS: Manjaro-ARM (PinebookPro) AARCH64 version 20.03
Installed glfw-x11, freetype2

What did you do?
Compiled tetris.v with no errors. Attempted to run tetris.

What did you expect to see?
A GL window with the TETRIS game, named TETRIS

What did you see instead?
gg error: GLX: failed to create GL context

Clearly, either a LIB is wrong or missing or I have done something silly.
Please point me in the right direction. When we get this error, what do we look at to find the missing or incorrect piece?
Is there and easy way to avoid this issue?

That's almost always a problem with your video driver, and/or OpenGL support therein.

[wpeckham]

Is there any fix? With a Pinebook I am pretty limited as far as making display or driver changes!

The only "fix" might be for V to back-level the version of OpenGL it wants to use, and that could affect everyone else adversely. Hopefully one of the OpenGL gurus will take a look, but I'm not guaranteeing anything.

[wpeckham]

After additional testing, it appears to affect every example that uses GUI. Not a major issue, as I mostly code background and text tools, just annoying. Thanks!

It’s an ARM CPU, but I’m sure there are GPU drivers for Linux.

[wpeckham]

Pinebook Pro supports OpenGL 2.1 and OpenGL ES 2.0. using the Midgard architecture. Not 3.0. Perhaps in a future version.....

Hm very weird seeing modern hardware only support OpenGL spec released in 1992, 28 years ago.

I have same problem on Manjaro-ARM (PinebookPro) AARCH64 version 20.03 (V version: V 0.1.29)
It use ARM Mali-T860MP4 GPU. Which support OpenGL ES1.1/2.0/3.0, OpenCL1.2, DirectX11.1.
So I think it support GL3.0

Mesa can do OpenGL 3.3 using CPU with soft rendering: https://docs.mesa3d.org/envvars.html .

$ LIBGL_ALWAYS_SOFTWARE=true glxinfo |grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
    Max core profile version: 3.3
    Max compat profile version: 3.1
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1
OpenGL core profile version string: 3.3 (Core Profile) Mesa 20.1.7
OpenGL core profile shading language version string: 3.30
OpenGL version string: 3.1 Mesa 20.1.7
OpenGL shading language version string: 1.40
OpenGL ES profile version string: OpenGL ES 3.1 Mesa 20.1.7
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10
    GL_EXT_separate_shader_objects, GL_EXT_shader_implicit_conversions, 

Rendering OpenGL with the CPU would be slow but should be fast enough for GUI toolkit. This can be done like:

$ LIBGL_ALWAYS_SOFTWARE=true ./tetris

OpenGL 3.3 was required by sokol.

The issue still seems to persist: pcmacdon/jsish#36 (comment)
