[ERROR] [RENDERER] Can't link program sprite: Fragment info

[DuendeInexistente]

I cloned and built the repo, but it fails to load the shaders.

The whole log is read weirdly by markdown, but here's the error:

This error appears to be because your GPU doesn't support indexing a uniform in the fragment shader. I found articles mentioning the error:

• https://www.gamedev.net/forums/topic/520607-error-c6013-only-arrays-of-texcoords-may-be-indexed-in-this-profile--and-only-wit/
• https://www.opengl.org/discussion_boards/showthread.php/163433-weird-error-in-a-Fragment-Shader
• https://stackoverflow.com/questions/10838089/which-version-of-glsl-supports-indexing-in-fragment-shader

Specifically mentions GeForce 7x cards, if you have one? Specific info for developers is that the fragment shader for sprites:

https://github.com/falltergeist/falltergeist/blob/develop/data/shaders/21/sprite.fp

Is indexing uniform int cnt[6]; in several places, which (as far as I understand) isn't allowed on older hardware and should instead be handled using a texture (e.g. make texture in app, pass to GPU, use texture mapping in GPU to derefence a sprite palette color, etc.)

Thanks for investigating the issue. We'll see what can be done here
