<h1>Qt Extended 4.4.2</h1>

<b>Note: this is an old version of Qt Extended.</b>

<h2>Installing on the FreeRunner</h2>

<h3>Download the kernel and rootfs</h3>

Download the kernel and rootfs to your workstation. Here's a link to the [http://other.lastnetwork.net/OpenMoko/qtextended-4.4.2-gta02-rootfs-release-working-with-SystemRingTones.jffs2 rootfs] created by Hypnotize. And here's the [http://qtextended.org/modules/mydownloads/visit.php?lid=91 mwebster flash image] containing the kernel. Boot your FreeRunner in dfu mode and use the dfu commands:

desktop# dfu-util -d 0x1d50:0x5119 -a kernel -R -D uImage-gta02-mwester-stable-d6f9fd270943fb22.bin

... stuff ...

desktop# dfu-util -d 0x1d50:0x5119 -a rootfs -R -D qtextended-4.4.2-gta02-rootfs-release-working-with-SystemRingTones.jffs2

... more stuff ...

<h3>Fix Echo Cancellation</h3>

On his [http://www.csamuel.org/2009/01/08/echo-suppression-fix-for-qt-extended-442-on-openmoko-neo blog] Chris Samuel explained how to turn on echo cancellation for qt extended 4.4.2. First you need to download an updated [http://www.csamuel.org/wp-content/uploads/2009/01/libneovendor.so neo plugin]. Secure copy the libneovendor.so file to your Freerunner, then secure shell to the FreeRunner and do this:

freerunner# cd /opt/Trolltech/Qtopia/plugins/phonevendors/
freerunner# mv libneovendor.so libneovendor.so.orig
freerunner# mv /home/root/libneovendor.so .

The change should take effect immediately.

<h3>The White Screen of Death (WSOD)</h3>

Sometimes when Qt Extended recovers from suspend you see a bright white screen. You don't have a phone anymore - you have a flashlight. Hold the power button down for about five seconds to power down the phone, then power it back up.

<h2>Compiling the Qt Extended 4.4.2 SDK</h2>

Start with a fresh Ubuntu 8.10 (Intrepid) install.

desktop# sudo aptitude update
desktop# sudo aptitude upgrade
desktop# sudo apt-get install kde-devel kde-devel-extras qt4-dev-tools build-essential thttpd patch libvorbis-dev

(sorry if I forgot some - might need to add some dbus packages)

Download the [http://qtextended.org/modules/mydownloads/visit.php?lid=97 SDK source] and [http://qtextended.org/modules/mydownloads/visit.php?lid=38 toolchain] from [http://qtextended.org qtextended.org]. Change directory to your machine's root directory then untar the toolchain - it will install itself to /opt/toolchains. Next create <tt>/opt/QtopiaSDK/qt-extended-4.4.2</tt> and <tt>/opt/QtopiaSDK/build</tt> directories. Unpack the Qt extended SDK source to <tt>/opt/QtopiaSDK/qt-extended-4.4.2</tt>. Set a pair of environment variables as follows:

desktop# export QTOPIA_DEPOT_PATH=/opt/QtopiaSDK/qt-extended-4.4.2
desktop# export QPEDIR=/opt/QtopiaSDK/build/qt-extended-4.4.2

I like to create a file called <tt>setqtpath-4.4.2</tt> with these two exports commands in them, which will look like this:

desktop# echo "export QTOPIA_DEPOT_PATH=/opt/QtopiaSDK/qt-extended-4.4.2" >> setqtpath-4.4.2
desktop# echo "export QPEDIR=/opt/QtopiaSDK/build/qt-extended-4.4.2" >> setqtpath-4.4.2

Now I can add these two variables to my environment whenever I want by sourcing them like this:

desktop# . setqtpath-4.4.2

Next download a pair of patches from mwester's openmoko stuff: [http://moko.mwester.net/download/pkg-config-template.patch pkg-config-template.patch] and [http://moko.mwester.net/download/qmemoryfile_unix_open_args.patch qmemoryfile_unix_open_args.patch]. Copy these to the qt-extended-4.4.2 source directory and execute these commands:

desktop# patch -p1 < qmemoryfile_unix_open_args.patch
desktop# patch -p1 < pkg-config-template.patch

Now change directory to the build directory. Execute the following:

desktop# cd $QPEDIR
desktop# $QTOPIA_DEPOT_PATH/configure -device neo -D _FORTIFY_SOURCE=0
desktop# make
desktop# make install

The <tt>-device neo</tt> is good for both Neo and FreeRunner. The <tt>_FORTIFY_SOURCE=0</tt> turns off some extra error checking that is turned on by default in many linux distros but borks the qt extended build process.

There's still something wrong which will cause errors. I don't know exactly what is wrong, but I googled a fix. Find the file <tt>
qt-extended-4.4.1/devices/neo/configure-common</tt> and change the line:

-add-modules pim
to
#-add-modules pim

<h2>Compiling an Example Qt Extended App</h2>

First set those indispensable Qt environment variables:

desktop# export QTOPIA_DEPOT_PATH=/opt/QtopiaSDK/qt-extended-4.4.2
desktop# export QPEDIR=/opt/QtopiaSDK/build/qt-extended-4.4.2

Next create a directory <tt>/opt/Qtopia/build/myapps</tt>. Copy the example app. Rename the example app to something that makes sense (how about "example"!). Create the <tt>Makefile</tt> and build the example.

desktop# mkdir /opt/Qtopia/build/myapps
desktop# cd /opt/Qtopia/build/myapps
desktop# cp -R $QTOPIA_DEPOT_PATH/examples/application .
desktop# mv application example
desktop# cd example
desktop# $QPEDIR/bin/qtopiamake
Finding Projects...
Writing 1 Makefiles...
desktop# make
make: running qbuild default
uic /opt/QtopiaSDK/build/myapps/application/examplebase.ui
moc /opt/QtopiaSDK/build/myapps/application/main.cpp
moc /opt/QtopiaSDK/build/myapps/application/example.h
arm-linux-g++ /opt/QtopiaSDK/build/myapps/application/.moc/moc_example.cpp
arm-linux-g++ /opt/QtopiaSDK/build/myapps/application/main.cpp
moc /opt/QtopiaSDK/build/myapps/application/example.cpp
arm-linux-g++ /opt/QtopiaSDK/build/myapps/application/example.cpp
arm-linux-g++ /opt/QtopiaSDK/build/myapps/application/example

Now you have an executable <tt>example</tt>. Of course, it won't execute on your workstation, you must secure copy it to your FreeRunner. Then secure shell into the FreeRunner, import the Qtopia environment variables and execute the app:

desktop# scp example root@freerunner:/home/rootroot@192.168.3.111's password:
example 100% 33KB 33.4KB/s 00:00
desktop# ssh 192.168.3.111
root@freerunner's password:
freerunner:~# . /opt/Trolltech/Qtopia/qpe.env
freerunner:~# ./example

You should see a message on FreeRunner's LCD.
