= Sources =
 
* Apart what i already mentioned here, some SL4P part are taken directly from the official Open Pandora OS.
 
* Sources are directly related to the build date, ie. if i upload a release the 1st april 2012, so the sources are related to the corresponding Open Pandora OS, rootfs, pandora-firmware, pandora-libraries, etc.
 
* Same thing for binaries coming from the official OP rootfs.
 
* About pre-compiled packages, shipped or not, grab the sources + SlackBuild accordingly to the version [http://slackbuilds.org/ here].

* It may look a bit messy for now (and indeed, some part have to be cleaned), but it's versatile, as i intended from the start.
 
* Depending on what you comment/uncomment, you can produce an alpha build, very minimal, or a full build.
 
* Depending on what you edit, you can use it to port any *NIX to Open Pandora, and maintain your build very easily

Disclaimer

  • Same as here.
  • The build system is GPL V3.

Principles

  • The target directory is likely to be a SD card. 8G recommended.
  • Phase 1 populates the target directory with the main ARMedslack Linux distribution.
  • Phase 2 populates the target directory with parts from official Open Pandora OS and tweaked stuff.
  • A specific part of rc.local is executed during the first boot on a Pandora.
  • The files folder contains tweaked stuff.
  • The pkg folder contains pre-built packages from a previous alpha build.
  • The sources folder contains sources for essential programs.
  • Some proprietary stuff is missing, like 3D drivers.

Get the build system

  • Get the archive here.
  • If you don't run a Slackware or a derivative, get the Slackware's installpkg script here.
  • Put it in /sbin and make it executable.

Dependencies

  • You need to download the official Open Pandora rootfs: http://openpandora.org/firmware/pandora-rootfs.tar.bz2
  • Uncompress it as root anywhere and link it to the build directory as "pandora-rootfs".
  • Format a 8G or more SD card with the Ext2 filesystem. To make explanations clear, name it SLACK.
  • If you don't know how to format a drive, use GParted under Linux, or run their Live-CD. Here's the manual.
  • It's highly recommended to have a second partition formated as a swap. 256M or more is a good choice.

Phase 1

  • Run as su -.
  • You'll see packages errors because it's a first run.

Phase 2

  • Run as su -.
  • For this very first alpha build, don't remove the SD card now, you have to edit ie.: /media/SLACK/etc/rc.d/rc.local

rc.local

  • Remove double-comments in order to produce the needed packages during the first boot.
  • Put the SD card in the Pandora, and power it on.
  • The Pandora will generate all (or almost all) needed packages.
  • The pandora will power off after having done the job. May last for one hour or two.
  • Remove the card.
  • Save /media/SLACK/tmp/*.t?z in the pkg folder of the build system.
  • Now, you can boot normally.
