For that reason that AVR-Microcontroller are used by Atmel you need to have a so called AVR-Toolchain for Linux and OSX, or WinAVR for Windows.
Linux-User can get this package i.e. with the following terminal-command: apt-get install gcc-avr avr-libc. For Mac OS X there is an installer available: Crosspack].
You translate the sources simply with "make" and you will get .hex-files which can be transferred to the device via an AvrDude.
