HelloWorld

Cross compiling elixir has always been PITA.

This is small example to cross-compile elixir app from MacOSX. It uses earthly.dev

Prerequisite

• Docker >= 19
• earthly

Command

# build otp release for pi as tarball
earthly +build

This will generate a tarball, which is compatible with raspberry pi 4. If you want to work with older version, tweak --platform value as per the hostnamectl info.

Note: I have not tried this with windows as docker host. It may or may not work.
