[maemo-developers] Ideas for Diablo and Elephanta: OpenEmbedded

[From: Rodrigo Vivi]

Hi Simon,

We are using the OpenEmbedded as build system of Mamona. After we have
all packages built by OE we add then to a .deb repository and after a
debootstrap installation in your pc you will be able to use the Mamona
environment with chroot + qemu. This is not an OE stuff but a Mamona
approach.

We use the OE to build packages, but we call the Mamona SDK the
chroot+qemu environment after the debootstrap install.

This SDK is a chroot + qemu, but it differs from scratchbox when it
doesn't have targets. it is simplest and more isolated. The use of
this sdk is to compile direct for ARM-EABI. Ok, thinking that emulated
compilation is slow we have setup a repository called noemu that have
packages like gcc and binutils that are i386 binaries that
cross-compile making it faster.

The idea is to have this emulated environment to developer compile and
test their programs and the OpenEmbedded to build the packages.
