1. How to use the Opie build system
====================================
There's a tutorial document at:
http://www.uv-ac.de/opiedev/opiedev.html

The API reference currently is at:
http://handhelds.org/~zecke/apidocs/index.html

You will need qvfb, uic and
(if you want to develop applications) designer
compiled and linked against Qt/X11.
That means you must download and configure/make it:
wget ftp://ftp.trolltech.com/qt/source/qt-x11-2.3.2.tar.gz
(Alternatively, you can get static binaries from http://www.vanille.de/tools)

You will need Qt/Embedded 2.3.10. Note that we don't support any
other Qt/Embedded version anymore. Qt/Embedded 2.3.12 is not recommended atm.

You can get it from:
ftp://ftp.trolltech.com/qt/source/qt-embedded-2.3.10-free.tar.bz2

Set QTDIR to point to your qt/embedded source tree, such as:
export QTDIR=/opt/qt-2.3.10

You need to do set the OPIEDIR environment variable:
export OPIEDIR=`pwd`
or
export OPIEDIR=~/projects/sources/opie
or wherever you placed the Opie sources.

You need to adjust your runtime library search path,
so that the Qt/Embedded and Opie libraries can be found:
export LD_LIBRARY_PATH=$OPIEDIR/lib:$QTDIR/lib:$LD_LIBRARY_PATH

You have to apply the patches corresponding to your Qt/Embedded version
and copy the qconfig-qpe.h file to $QTDIR/src/tools:
cd $QTDIR; cat $OPIEDIR/qt/qt-<version>.patch/qte<version>-all.patch | patch -p1
cp $OPIEDIR/qt/qconfig-qpe.h $QTDIR/src/tools

You are now ready to configure and build Qt/Embedded

cd $QTDIR
echo 'yes' | ./configure -qconfig qpe -depths 4,16,24,32 -system-jpeg -system-libpng -system-zlib -no-xkb -no-sm -no-xft -qvfb
make

Note that the above command ( -qvfb ) compiles in the Virtual 
Framebuffer and is mostly meant for development on your host system.
For cross compiling, you will need to use the -xplatform switch.
See ./configure --help for details about the possible options.

Once you have these compiled, be sure to set the PATH to ensure your (cross)compiler
is available.

Then do the following in the opie source tree:

make clean
make menuconfig

Now you can move through the menu and select or deselect anything..
Exit and save the configuration and enter "make" to build everything selected.

Have fun!
