Get a build host.

You need 32-bit (i386) libraries for the code sorcerer toolchain. One simple way to do this is in an i386 chroot or virtual machine.

Install the build pre-reqs.

In a fresh minimal Debian Unstable install,

% sudo apt-get install git build-essential zip gawk libtool gettext  \
      automake autoconf  nasm unzip gettext flex bison libsdl-image1.2 \
      liblzo2-2 lzma python openjdk-7-jre-headless \
      texinfo libxml-parser-perl wget pkg-config swig cpio zlib1g-dev \
      libgmp-dev libmpfr-dev subversion
      libncurses5-dev autopoint

Note that as of current (2012-10-10) Debian Unstable, python defaults to python 2.7. Earlier pythons (or python3) will not work.

Set up a key to sign the image

% keytool -genkey -keystore ~/.android/debug.keystore -v -alias \
      androiddebugkey -dname "CN=Android Debug,O=Android,C=US" -keypass \
      android -storepass android -keyalg RSA -keysize 2048 -validity 10000

Build

First configure the source tree for the device you want to compile the image for. The following devices are supported at this moment;

  Pivos XIOS DS M1 == amlogic_xios-xbmc_defconfig

  Pivos XIOS DS M3 == amlogic_xios_m3-xbmc_defconfig

  Refee/OE Smart TV Box == amlogic_f16ref_gbox_1-xbmc_defconfig

  GBox Midnight v2.0+ == amlogic_f16ref_gbox-xbmc_defconfig
  
  GBox Midnight v2.0 == amlogic_f16ref_gbox_1-xbmc_defconfig

  Sumvision Nano M1 (non slim) == amlogic_stvmc-xbmc_defconfig (Actually the same as the xios M1)

  Sumvision Nano M3 (slim) == amlogic_stvmc-xbmc_defconfig

  Geniatech/MyGica Enjoy TV 510b == amlogic_stvmc-xbmc_defconfig

  MyGica A11 == amlogic_stvmc_mygica-a11-xbmc_defconfig

So run one of the following commands

% make amlogic_xios-xbmc_defconfig

or

% make amlogic_xios_m3-xbmc_defconfig

or

% make amlogic_f16ref-xbmc_defconfig

or

% make amlogic_stvm3-xbmc_defconfig

or

% make amlogic_stvmc-xbmc_defconfig

or

% make amlogic_stvmc_mygica-a11-xbmc_defconfig

Then build the update file

% make
