panic: ErrorCode(65546): Cannot make current with a window that has no OpenGL or OpenGL ES context #744

Hi! I tried to compile the Hello World example but I got the following error message at run time

GLFW: An invalid error was not accepted by the caller: ErrorCode(65546): Cannot make current with a window that has no OpenGL or OpenGL ES context
GLFW: Please report this bug in the Go package immediately.
panic: ErrorCode(65546): Cannot make current with a window that has no OpenGL or OpenGL ES context

My system spec

OS: Ubuntu 20.04 Nvidia driver: 450.80.02 Golang: version go1.15 linux/amd64 Engo: 1.0.5

Libraries libgl1-mesa, libglx, libglew, libglfw3, libgles are installed. I can compile and run Unreal Engine demos so I think that the problem is related to the Golang development environment.

Hello!

Using the tip of master as well as engo v1.0.5 I can't replicate on macOS with go1.15.3

It looks like the issue is on the GLFW side. Do you know if you're using Wayland instead of X? If so, I believe glfw 3.3 needs the Wayland build tag to work. Might be related to https://github.com/go-gl/glfw/issues/278. If so, I can update the glfw version to the latest once that gets put in.

ETA: My Linux box is currently out of commission, so I'm not sure when I'll be able to test it out on Linux / Wayland

Thank you for your immediate response. I'm using Xorg with gnome-session. The Hello World example works fine with MX Linux 19.2, KDE flavor. I did a fresh install of this Linux distro, then I installed golang and xorg-dev. No problem. Then I think that Ubuntu 20.04 comes with GL libraries that cause the program to start panicking.

My fault. I also imported another package that uses go-glfw causing the run time error. Sorry for this quid pro quo. Problem solved.
