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:



2018/11/21 13:43:33 PlatformError: X11: The DISPLAY environment variable is missing
panic: NotInitialized: The GLFW library is not initialized

goroutine 1 [running, locked to thread]:

And if you are curious, my go env:

Any help would be appreciated, thanks!



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:



# _/home/oriont/dev/super_g
/usr/lib/go-1.11/pkg/tool/linux_amd64/link: running gcc failed: exit status 1
/usr/bin/ld: cannot find -lXrandr
collect2: error: ld returned 1 exit status


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.

    First try to 'echo $DISPLAY' to check if the variable is there, then try 'export DISPLAY', then run your program.

    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.

  • 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.
