To choose the proper one:

just take the OE.mtn.bz2 file and, once the database uncompressed, run a mtn --db=/stuff/OE.mtn db migrate
or, take the OE-this-is-for-mtn-0.3x.mtn.bz2 that is in keeping with the version of your monotone program (checked with mtn --version).

Read comments in it as it will bring you valuables informations and allow you to adapt it to your own environment and building host (directory structure for example).

In addition, some environment variables have to be set before running a build process. We setup those variables via a little script env-oe.sh :

#!/bin/sh

OE_DIR=/stuff

export PATH=${OE_DIR}/bitbake/bin:$PATH
export BBPATH=${OE_DIR}/build:${OE_DIR}/org.openembedded.dev

Then, source this script :

source ./env-oe.sh

Start building

Begin with a little set of packages :

bitbake angstrom-minimal-image

even a minimal image will require a big amount of time because of the cross-toolchain building process.

bitbake angstrom-x11-image-demo

 Getting OpenEmbedded 

Once in your OpenEmbeddedDirectory, download a snapshot of the OpenEmbedded monotone database going to http://www.openembedded.org/snapshots/.

To choose the proper one: 

 just take the OE.mtn.bz2 file and, once the database uncompressed, run a mtn --db=/stuff/OE.mtn db migrate
  or, take the OE-this-is-for-mtn-0.3x.mtn.bz2 that is in keeping with the version of your monotone program (checked with mtn --version).
 

Before uncompressing the OE database, it is recommended to verify its integrity :

 Getting OpenEmbedded 

Once in your OpenEmbeddedDirectory, download a snapshot of the OpenEmbedded monotone database going to http://www.openembedded.org/snapshots/.

To choose the proper one: 

 just take the OE.mtn.bz2 file and, once the database uncompressed, run a mtn --db=/stuff/OE.mtn db migrate
  or, take the OE-this-is-for-mtn-0.3x.mtn.bz2 that is in keeping with the version of your monotone program (checked with mtn --version).
 

Before uncompressing the OE database, it is recommended to verify its integrity :
md5sum -c OE.mtn.bz2.md5sum

Note that building an entire distribution is a long process. It also requires a big amount of free disk space ; at least :

~650 MByte of source archives downloaded for Internet
~5 GByte of compiled packages and tools

This documentation is largely inspired by the following resources :

Angstrom simple build instruction : http://www.angstrom-distribution.org/building-angstrom
building gpephone (building angstrom example) : http://linuxtogo.org/gowiki/BuildGpepeUsingOpenEmbedded
building openmoko : http://wiki.openmoko.org/wiki/Building_OpenMoko_from_scratch
OpenEmbedded from scratch using a chrooted Debian environment : http://wiki.emqbit.com/openembedded

To build the binary found above, you will have to go through the following steps.

Build Process with OpenEmbedded

OpenEmbedded upstream snapshot

We start from an OpenEmbedded snapshot from the official "upstream" OpenEmbedded project. This snapshot contains the BitBake recipes for thousands of packages.

OE release : aa44d626baaae40ee498aea453176a8aea90d9fc

mtn --db=../oe_snapshot/OE.mtn checkout -r aa44d626baaae40ee498aea453176a8aea90d9fc --branch=org.openembedded.dev

mtn diff -r aa44d626baaae40ee498aea453176a8aea90d9fc -r `mtn automate heads` | vim -

AT91 OpenEmbedded/Angstrom overlay tree

In addition to the upstream recipes, we also have a set of our own recipes.

The overlay tree works in the following way: It gives us the ability to add rules below a separate directory tree. This means we don't have to edit or add rules to the upstream snapshot, and we always have a clear distinction about what is upstream, and what is our additions to it.
