Support for ARM (armv7l) #32

Open vitalydolgov opened 2 years ago

vitalydolgov commented 2 years ago

Are there any plans for ARM support, particularly armv7l? It seems, there is no configuration available, for example, this happens on Raspberry Pi 4:

Unfortunately, we don't support ARM ourselves. See #26. If you fix the problem yourself, though, please send us a pull request.

Sorry for the long delay. I was out until recently.
