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
In chroot'ed environment
set environment variables
DISPLAY=:1
LANG=C
HOME=/home/root
export DISPLAY LANG HOME
Create pango.modules file
pango-querymodules > /etc/pango/pango.modules
Create gdk-pixbuf.loaders file
gdk-pixbuf-query-loaders > /etc/gtk-2.0/gdk-pixbuf.loaders
Remove touch screen calibrator. Since touch screen hardware is not present, the touch screen calibration prevents X start-up on PC.
rm /etc/X11/Xsession.d/30xTs_Calibrate
Start an X Session:
/etc/X11/Xsession
Start nested X server
In another terminal (not related to mokobox), start Xephyr
Xephyr :1 -ac -2button -host-cursor -screen 480x640
You should see OpenMoko booting in the Xephyr window.
