    That GLFW error is [GLFW_PLATFORM_UNAVAILABLE](https://www.glfw.org/docs/3.4/group__errors.html#ga3608c6c29ab7a72f3bf019f4c3a2563d). What version of GLFW? What Linux distribution? Are you using WSL? Is your system using X11 or Wayland? – ad absurdum Jul 15 '23 at 20:01

WARNING: GLFW: Error: 65550 Description: X11: Failed to open display :0

This error is unrelated to GL, but to the underlying XWindow system protocol. It is telling you that the X11 server to display the graphical stuff has not been reached.

:0 display should be your local display in the machine (it's indeed the local display you will probably being running, or not). I need to know how are you running your display environment. You should be running an XWindows or wayland (with xwindows support) to be possible to connect to the X server. It can also be some authentication error, or for some reason you have initialized as a fixed string your DISPLAY environment variable (this should be the variable that holds the :0 string)
