This repository contains all required infrastructure to allow you to build your Arduino projects without actually having an IDE nearby.
You are free to forget about *.ino files and Arduino IDE, just setup the toolchain, use main.cpp as a skeleton and you are free to go.
NOTE: only Arduino Nano board were tested (I only have this guy). But the base Makefile should work for any Arduino-based libraries.
In order to be able to compile under GCC and upload firmware files you need:
avr-binutilsavr-gccavr-libcavr-dude
Our installation directory will be /usr/local/avr/ and OS is Fedora.

# Note: because `install` target that runs `/bin/sh` can't find `avr-ranlib` no matter what
# (expanding PATH doesn't work), we do `make install` from root
