Getting OpenMoko working on host with Xephyr

Revision as of 23:58, 2 May 2007

The goal of this page is to show you how to run an OpenMoko development image on your host x86 development machine in a chrooted environment.

Build an image

First, you should use Building OpenMoko using the MokoMakefile to build an openmoko-devel-image for your host architecture (x86 in our case). Make sure you put the moko makefile in /home/moko/Makefile .

Prior to that, edit your build/conf/local.conf to make it look like this:

MACHINE = "qemux86"
DISTRO = "openmoko"
BUILD_ARCH = "i686"
INHERIT += " devshell"
SRCDATE_eds-dbus = "now"

Once you have built the image, you can start working toward running the image.

Setup the image filesystem

The filesystem of the image can be found at /home/moko/build/tmp/rootfs . It is that image that we want to run in a chrooted environment.

We will copy that that rootfs directory somewhere so that subsquent builds (using the MokoMakefile for instance) don't overwrite it.

Make sure you have root privileges:

su -

Copy the rootf into a directory called MokoBox. From now on, we will call the chrooted environment a MokoBox.

cp -r /home/moko/build/tmp/rootfs /home/moko/mokobox

make sure /dev and /proc of the host machine are visible from within mokobox

mount --bind /dev /homo/moko/mokobox/dev
mount -t proc none /home/moko/mokobox/proc

start the mokobox

chroot /homo/moko/mokobox /bin/sh

set environment variables

DISPLAY=:1
LANG=C
HOME=/home/root
export DISPLAY LANG HOME

Set-up pango

pango-querymodules > /etc/pango/pango.modules

Start nested X server

In another terminal (not related to mokobox), start Xephyr

Xephyr :1 -ac

You should see the window of Xephyr now.

Now, back in the mokobox, start an X Session:

/etc/X11/Xsession

You should see OpenMoko booting in the Xephyr window.
