Host-based development

This term means you develop most of your application in your standard desktop environment until it's almost finished. Then you can use a Toolchain to cross-compile your application for the Neo1973. Host-based development is incredibly more efficient since you can use your (typically) fast computer, large monitor, etc.

Xoo and Xephyr

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.

Note that Xoo is not required to simulate OpenMoko hardware - it just improves the presentation.


Part I (precompiled software)

You need to install some software that is usually not present on a desktop system, but used on the Neo1973. Some of this software has already been precompiled by your friendly distribution packager, so you don't need to compile it yourself. Most likely you can install the following packages from your distribution repository:

  • xephyr
  • xoo
  • matchbox-window-manager
  • matchbox-keyboard
  • libgtk2.0-dev
  • libecal1.2-dev

Gentoo users run just

# emerge <package>


$ sudo apt-get install <package>

For Fedora, you can use

# yum install <package>

For Mandriva, you may try

# urpmi <package>

for any other find a way how to do it in your distro.

Part II (building from source)

You also need some software that is typically not found in your distribution repository, either because it's too new, too specific, or unheard of.

Most likely you will need to compile the following packages for your distribution:

  • matchbox-panel-2
  • libjana
  • libipkg

To compile and install matchbox-panel-2:

mkdir -f /local/pkg/ohand
cd /local/pkg/ohand
svn co matchbox
cd matchbox/matchbox-panel-2
make install

To compile and install libjana:

mkdir -f /local/pkg/ohand
cd /local/pkg/ohand
svn co jana
cd jana
make install

To compile and install libipkg:

mkdir -f /local/pkg/
cd /local/pkg/
tar xzf ipkg-0.99.163.tar.gz
cd ipkg-0.99.163
make install

Building the OpenMoko applications

First we download the OpenMoko subversion repository:

 mkdir -f /local/pkg/openmoko
 cd /local/pkg/openmoko
 svn co src

Then you compile the software contained there, e.g. you will definitely want to compile at least:

In directory src/target/:

  • gsmd

In directory src/target/OM-2007.2/libraries/:

  • libmokoui2
  • libmokopanelui2
  • libmokojournal2
  • libmokogsmd2

In directory src/target/OM-2007.2/daemons/:

  • neod

In directory src/target/OM-2007.2/panel-plugins/:

  • openmoko-panel-gsm
  • openmoko-panel-usb
  • openmoko-panel-battery
  • openmoko-panel-gps

In directory src/target/OM-2007.2/applications:

  • openmoko-today2
  • openmoko-calculator2
  • openmoko-appmanager2

Each of these packages are to be compiled by the well-known-triple of:

./configure (or ./, if it's the first time)
make install

Starting the nested OpenMoko

Launch Xoo

In another terminal (not related to mokobox), start Xoo. Download [1] and run for a nice neo 1973 theme.

# xoo --device neo1973.xml

Using Xnest without xoo

If you don't want to use xoo (perhaps you don't have the required resolutions to display the large image) you can use Xnest on its own,

# Xnest :1 -dpi 283 -geometry 480x640+86+295

(if you get "Xnest: client 1 rejected from IP", try running Xnest with the -ac flag)

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.

Set your theme to OpenMoko

If you find that graphics within Xnest & xoo are broken, try the following:

  • Add a user and group 'messagebus', on some systems by adduser, on others by editing /etc/passwd and /etc/group)
  • Start dbus:
 /etc/init.d/dbus-1 start
  • Register pango modules
 pango-querymodules > /etc/pango/pango.modules
  • Set the GTK2_RC_FILES variable before running OpenMoko applications:
 export GTK2_RC_FILES=$OPENMOKODIR/artwork/themes/openmoko-standard/gtk-2.0/gtkrc

Or edit $HOME/.gtkrc-2.0 to something like this:

 include "/home/moko/openmoko/trunk/src/target/OM-2007/artwork/themes/openmoko-standard/gtk-2.0/gtkrc"

However, this will make all Gtk2 apps run with the OpenMoko theme.
