does not launch game window

[Marie-Joseph]

When running the examples as described in the documentation, "basic.jl" throws the following error:

ERROR: MethodError: Cannot `convert` an object of type

"basic2.jl" warns about being unable to find ALSA libraries but otherwise simply does not launch a game window:

┌ Warning: No audio device available, sounds and music will not play.

This same bug was brought up in #42, a workaround was discussed there that should help you

Sorry I just saw this - pointing an environment variable at the alsa conf file, as is suggested in the issue linked in the issue you linked, just gets me what sounds like bugged audio, but still no game window, for basic.jl

for basic2.jl, I just get ALSA lib control.c:1481:(snd_ctl_open_noupdate) Invalid CTL hw:0

It shows up in the tracebacks but I should probably explicitly mention: I'm on Guix GNU/Linux
