The bug Hi, I was installing this on the newest RaspberryPi OS, that ships with python 3.9, and the install step failed, as the native compile for RPI.GPIO package failed

Following this stack overflow issue I added CFLAGS=-fcommon to the pip install inside the VENV, that solved the problem just fine

Just wanted to report this here :-)

Debug output ...

To Reproduce Just install the version from the 3.0.0 Branch
