#189 Installation fails with python 3.8.5 in archlinux

[Sergio Alejandro Gonzalez]

First, thank you for the project anf for the trmendous effort in maintaing.,
I'm a long time user with Archlinux in the RPi3.

Nevethles, today I resintalled a ARM RPi 3 with new archlinux, staring from zero and I could NOT install it.

my current system is:
Python 3.8.5 (default, Jul 29 2020, 13:52:15)
[GCC 9.3.0] on linux
Linux 5.4.51-2-ARCH #1 SMP PREEMPT Sat Aug 8 23:15:12 UTC 2020 armv7l GNU/Linux

Please see:

Thank you Ben, it seems you are right, although #187 is using GCC 10....please don't hesitate if you need some help sorting this out...
