Currently releases require the OS and architecture to match. However, Erlang/OTP does support cross compilation, so at least a possibility is there, it needs to be further explored: http://erlang.org/doc/installation_guide/INSTALL-CROSS.html http://erlang.org/doc/installation_guide/INSTALL-CROSS.html The other concern is packages with NIFs (native code) and they would need to be changed if they don't support cross-compilation yet. I believe Nerves, which is an Elixir framework for embedded, does a good amount of cross compilation too but they have a more controlled environment.
