= Bash knowledge =
* You need minimal bash knowledge in order to understand and succeed. [http://en.wikipedia.org/wiki/Bash_%28Unix_shell%29 This] is a good start.
* Each script contains comments. Read them.

* rc.local will be copied and executed automatically on the Pandora. You have to tweak it before Phase 1 or Phase 2.

* Put the SD card in the Pandora, and power it on.
* The Pandora will build many needed packages, but not all listed, because of some dependencies installed later through sbopkg.
* You have to edit the OPP="" and MHZ="" variables at the top of the script for your Pandora unit(s). These will only be used during the build phases.

* Now, you can unmount the card and boot normally this alpha build on the Pandora.

MYPKGS="$CWD/pkg"
folder of the build system.
 
= In-between steps =
* Plug the net.
* Launch sbopkg as su -, load the vrac1 queue file, process it saying yes (Q) to options and wait. This is gonna be very long. I really mean very.
* Do the same with vrac2 and vrac3.
* Save all /tmp/*.t?z in the
MYPKGSMORE="$CWD/pkg-more"
folder of the build system.
* Be careful with disk space, you may fill the card. If so, save and erase all /tmp/*.t?z, and sources inside /var/cache/sbopkg/ between queues processing.
* Note that i include other packages listed in other queue files in my own release. If you plan to do so, move them in MYPKGSMORE="$CWD/pkg-more".
 
= Final step =
* Populate a new SD card, with PHASE-1.sh and PHASE-2.sh
* Edit /media/SLACK/etc/rc.d/rc.local to build the remaining packages to put in MYPKGS="$CWD/pkg"
* Put the SD card in the Pandora, and power it on.
* Put the SD card in the Pandora, and power it on.
* The Pandora will generate final needed packages.

* Save all /media/SLACK/tmp/*.t?z in YPKGS="$CWD/pkg" folder of the build system.
* Save /media/SLACK/tmp/*.t?z in the pkg folder of the build system.
* Now, you can create a complete SL4P system.
* Now, you can boot normally.
 
= Creating a compressed rootfs =
* Populate a SD card. Now you should know how to do it ;^).
* Boot it on a Pandora.
* Once the Pandora shuts down, remove the card, and follow [http://pandorawiki.org/How_to_back_up_a_Root_File_System_%28on_an_SD_Card%29_to_an_SD_Card this] procedure.
 
= Special packages =
* In the sources folder, you'll find some programs that aren't automatically generated by the build system.
I don't list those dependencies for now, because i do more useful things ^^.
* XMMS may just needs libmikmod.
* Qt3 is a bit long to build. It should be built before the big playlist.
 
= 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].
* If some package version changed, you have access to the old data using [http://slackbuilds.org/cgit/slackbuilds/ sbopkg git repo].


= Notes =
* 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
* The -current build system is under work and is not released yet.


= Ask a question/Report a bug =
* You're welcome, and please post here: http://boards.openpandora.org/index.php?/topic/1524-slackware-inside-pandora/

Revision as of 07:16, 18 August 2013

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.
