As earlier for Ubuntu, I used the same quick-and-dirty package creation method and created AVR-Ada package for Raspberry Pi 1 running Debian Wheezy.
You can get the package from rpi1.ada-language.com by adding line:
deb http://rpi1.ada-language.com/wheezy ./
to your /etc/apt/sources.list file and running:
sudo apt-get update sudo apt-get install avr-ada
The package is not signed, so you need to say Yes ('y') when apt-get asks about the installation of the package.
The installed binaries go to /usr/local/avr-ada-122 directory.
The build script can be found from https://bitbucket.org/tkoskine/avr-ada-build-script (branch raspberry-pi-wheezy).
Once the build script has compiled and installed avr-gcc and AVR-Ada, you can package the results with fpm:
fpm -s dir -t deb -n avr-ada -v 1.2.2 /usr/local/avr-ada-122
