Building

Couples things had to be done to compile on the Pi (no cross-compilation yet). Had to install a couple of packages and enable eudev.

The packages I installed (apk add):

• linux-headers
• libudev-zero --repository="https://dl-cdn.alpinelinux.org/alpine/edge/community"
• eudev-dev
• eudev
• udev-init-scripts

I also ran this script, not sure if it was needed:

• setup-devd udev

I'll need to do a fresh install to see what really needs to be installed. I also really want to cross compile since it takes forever on the Pi.

On alpine linux, to enable i2c you need to change some stuff in /etc/modules and /boot/config.txt. This article explains it.

The changes:

• /boot/config.txt you have to add dtparam=i2c_arm=on.
• /etc/modules you have to add i2c-dev.
