Error Installing rpi-lgpio on Docker

[velison1-mbed]

I am attempting to dockerize my Python project on a Raspberry Pi Zero W. I am using the balenalib/raspberry-pi-python:3.11.2-bookworm-build base image. When I try to install the rpi-lgpio package, I encounter an error. Here are the details of the error:

Ohhh, arm6l. Of course, I'd forgotten that arch...

Note to self: check the "arm7l" wheels to see if they're actually arm6l; if not, rebuild on raspios on a true arm6l board

I have installed swig with dockerfile and it fails building for arm64:

@Ed1ks I noticed this line:

/usr/bin/ld: cannot find -llgpio

I had the same problem when trying to migrate my project from rpi3 to rpi4, and the only thing that worked was installing the lgpio module, following the instructions found here: https://abyz.me.uk/lg/download.html

Hope this helps!

I just hit the same issue trying to install the lgpio package on a pi zero w (also armv6l). I had to do a pip install swig since there appear to be dependency issues with the debian swig package.
