Vedere anche Far funzionare OpenMoko su host con Xephyr, è probabile che contenga informazioni più aggiornate.
Cosa è Xoo
Xoo is a GTK2 based graphical wrapper around a ‘Windowed’ X Server. The X server is typically Xnest, the nested X server, or Xephyr. It is intended for embedded developers that want to simulate a target device (with an accurate display size, working hardware buttons, etc) on a desktop machine.
Currently only getting Xoo working with Xnest is discussed here. Instructions for running Xoo with Xephyr are planned.
Xoo is not required to simulate OpenMoko hardware - it just improves the presentation
Install Xoo on your host
For gentoo users run just
# emerge xoo
Debian/Ubuntu
# sudo apt-get install xoo xnest
For Fedora (package has been submitted to Fedora for approval, see https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=236297):
# ftp://ftp.xelerance.com/xoo/
for any other find a way how to do it in your distro.
Build an OpenMoko Image (Getting rootfs)
First, you'll need to build an openmoko-devel-image and get rootfs. One good way to get started developing is getting rootfs working on host machine, since most of us don't have real hardware.
You should use Building OpenMoko using the MokoMakefile to build an openmoko-devel-image for your host architecture.
Prior to running make openmoko-devel-image to get rootfs (before step 5) run :
# sed -i 's/fic-gta01/x86/' build/conf/local.conf
then just run make openmoko-devel-image. After a while (half a day) the build should complete.
You might need to add
TARGET_FPU = ""
to your build/conf/local.conf to avoid:
NOTE: <type 'exceptions.Exception'>:variable TARGET_FPU references itself! while evaluating:${TARGET_FPU}
errors.
Build issues
Please see this bug tracker issues if you have problems getting libelf compiled (do_stage fails).
Setup the Image Filesystem
The filesystem of the image can be found at build/tmp/rootfs . It is that image that we want to run in a chrooted environment.
This image should also be packed/compressed as the file openmoko-devel-image-x86-$(DATE).rootfs.tar.gz in build/tmp/image/ - mine is here [1].
Making X cooperate
- Make sure your iptables do not prevent you from connecting to port 6000(x11) on localhost
- Make sure your X is listening on port 6000(X11) on localhost (netstat is friend)
- Enable conection from localhost
# xhost localhost
Preparing rootfs
Unpack the rootfs file and copy the contents into a directory called /home/moko/mokobox. This will be our chrooted environment.
make sure /dev of the host machine are visible from within mokobox
# sudo mount --bind /dev/ /home/moko/mokobox/dev
Start/Move into the protected mokobox environment
# sudo chroot /home/moko/mokobox /bin/sh
Starting the nested X server
Launch Xoo
In another terminal (not related to mokobox), start Xoo. Download [2] and run for a nice neo 1973 theme.
# xoo --device neo1973.xml
Start X Client
Now, back in chroo'ted environment, start X client:
Export display to connect to started xoo
# export DISPLAY=localhost:1.0
Start window manager.
# x-window-manager
By this time you should have Xnest & Xoo running OpenMoko in a window.
