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.
Prerequisites
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>
Debian/Ubuntu
$ 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 http://svn.o-hand.com/repos/matchbox/trunk matchbox
cd matchbox/matchbox-panel-2
./autogen.sh
make install
To compile and install libjana:
mkdir -f /local/pkg/ohand
cd /local/pkg/ohand
svn co http://svn.o-hand.com/repos/jana/trunk jana
cd jana
./autogen.sh
make install
To compile and install libipkg:
mkdir -f /local/pkg/handhelds.org
cd /local/pkg/handhelds.org
wget http://downloads.openmoko.org/sources/ipkg-0.99.163.tar.gz
tar xzf ipkg-0.99.163.tar.gz
cd ipkg-0.99.163
./configure
make install
Building the OpenMoko core
First we download the OpenMoko subversion repository:
mkdir -f /local/pkg/openmoko
cd /local/pkg/openmoko
svn co http://svn.openmoko.org/src/trunk src
Then you compile the software contained there, e.g. you will definitely want to compile at least:
In directory src/target/:
In directory src/target/OM-2007.2/libraries/:
- libmokoui2
- libmokopanelui2
- libmokojournal2
- libmokogsmd2
In directory src/target/OM-2007.2/daemons/:
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 ./autogen.sh, if it's the first time)
make
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 127.0.0.1", 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
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.
