How to use GLFW / OpenGL ES on Armbian

[flyx86]

Hi folks,

I am trying to write a small application that renders stuff using OpenGL ES on Armbian. I enabled 3D video acceleration via the RK3328 Media Script. Now I'm trying to create a simple window with an OpenGL context on it, using GLFW:

Code:

if err := glfw.Init(); err != nil {
 panic(err)
}
defer glfw.Terminate()

glfw.WindowHint(glfw.ClientAPI, glfw.OpenGLESAPI)

window, err := glfw.CreateWindow(640, 480, "Testing", nil, nil)

(This is Go, but I think the programming language is not really relevant.)

I compile and link that using -lGLESv2 and GLFW's dependencies, which produces a binary. However, when I execute that, I get:

Code:

libGL error: unable to load driver: rockchip_dri.so
libGL error: driver pointer missing
libGL error: failed to load driver: rockchip
2019/04/14 16:46:56 Link error in program Program(0): ""

So for some reason, my executable uses libGL instead of libGLESv2, and that doesn't work, since the rockchip only supports OpenGL ES. I have no idea why that happens. ldd ensures me that my binary is not linked against libGL.

How can I fix that? Is there perhaps a better Linux distribution for development? I tested Debian before, but that wasn't even able to install X11 and was pretty bricked after I tried.
