$ make test
Testing Sauce...

named files must be .go files: sauce/go.mod

make build works perfectly but the binary doesn't run

I've ran these make commands in git bash install on windows.
and renamed the bin/thdwb build file to bin/thdwb.exe and tried to run it

The error on line 23 is unchecked so something went wrong.
You might try to insert:

if err != nil {
    log.Fatal(err)
}

Before line 24, make run, then paste the error here.

[ajzaff]

It's likely that the error is related to your version of opengl. This only aims to support 4.1 which is fine if it's in your profile, but would return an error if it's not available.

If you're on wsl you can try

sudo apt install mesa-utils
glxinfo | grep "core profile"

To find supported core GL version.

Then, to get it running, you can change all "github.com/go-gl/gl/v4.1-core/gl" imports to a supported version and change the window hints here: https://github.com/danfragoso/thdwb/blob/master/mustard/window.go#L16-17

Longer term would need to add support for older versions of gl.
