Golang OpenGL Error PlatformError: X11: The DISPLAY environment variable is missing panic: NotInitialized:...
I just cannot seem to get opengl with golang to work. I wanted to try out golang but it has been such a pain to even set up, and now I can't get something I copy pasted off of this website. Here is the code I am using: (from the website). I did these two commands before running it (using wsl on windows):
go get github.com/go-gl/gl/v4.1-core/gl
go get github.com/go-gl/glfw/v3.2/glfw
And this is the full error I am getting:

EDIT:
Now I am getting a new error, after reinstalling go and removing a failed attempt at sdl2 (from apt-get remove).
(OLD) This is the new error:

I have all of the same code still. Also, I did try to run 'go build' but it just threw the exact same error as 'go run main.go'.
EDIT 2:
I reinstalled go 1.11.2 and installed the libglfw3 and libglfw3-dev packages on sudo apt-get install. Now, I have the same old error.

My solution is to literally install GoLang and TDM-GCC on windows, and do it through the command prompt INSTEAD OF BASH.

You didn't mention you were using Windows Subsystem for Linux. This is important information. That is a stripped down "Linux" which only supports command line programs, not GUI programs. To run a Linux GUI program, you need to run a full installation of Linux, not just WSL.

When I run 'echo $DISPLAY', a blank line shows up. I tried 'export DISPLAY' and ran my program, and I got the same error. After that, I echoed it again and it was still a blank line.

I am using 'go run main.go', with main.go containing all my code. I just tried 'sudo go run main.go' with the same result.
