"Unable to get connector" when using a Pi Compute Module 4 about rpi-opengl-without-x HOT 2 OPEN

Hi @n8allan

If I understand, you have managed to get to this point:

EGLContext context = eglCreateContext(display, configs[configIndex], EGL_NO_CONTEXT, contextAttribs);

without initializing the display (since you do not have one)? Would you be able to share your code?

Here's the code so far.

I ran into a problem with the compute shader compiler complaining about not supporting ES 3.1, I deduced that it was probably my older version of the OS, so I've updated to 64-bit Bullseye. I now get the following GL info:

version: "2.1 Mesa 20.3.5"
  shading language version: "1.20"
  vendor: "Broadcom"
  renderer: "V3D 4.2"

The mesa version is now newer, but it still doesn't list ES 3.1 as a supported version.

The error:

Error in compiling the compute shader
Compiler log:
0:1(10): error: GLSL ES 3.10 is not supported. Supported versions are: 1.10, 1.20, 1.00 ES, and 3.00 ES
0:0(0): error: Compute shaders require GLSL 4.30 or GLSL ES 3.10
