Cross compling from sources in debian chroot

• The most easy and painless way is to build QtMoko in debian squeeze chroot.

• You will need debian on your PC

• Clone current git tree:

git clone git://github.com/radekp/qtmoko.git

• Initialize and update submodules

cd qtmoko git submodule init git submodule update

• Create and enter debian chroot:

sudo scripts/qtmoko-chroot-armhf.sh

• Build it:

mkdir -p /root/qte/build cd /root/qte/build ../qtmoko/configure -device gta04 make export LD_LIBRARY_PATH=/root/qte/build/qtopiacore/host/lib/ make install

• If you have e.g. 8 core processor you can speed it up by passing -j8 arg to configure and make.

• Upload the result to your device (you must have phone and usb network up)

../qtmoko/devices/gta04/scripts/update_qtmoko

Native compiling on GTA04

• Very easy to setup, takes long time, can produce QtMoko armhf package

• You will need working QtMoko installation on at least 8GB partition

• Linking takes a lot of memory, so will need swap:

dd if=/dev/zero of=/swapfile bs=1024 count=1048576 mkswap /swapfile swapon /swapfile

• Install QtMoko dependecies:

apt-get update apt-get install git quilt debhelper build-essential libtiff4-dev libmng-dev quilt libxext-dev libasound2-dev libdbus-1-dev libssl-dev libts-dev libbluetooth-dev libxtst-dev libpng12-dev libjpeg8-dev libv4l-dev libspeexdsp-dev libglib2.0-dev libsqlite3-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libpulse-dev libvorbis-dev libgps-dev

• Get sources:

git clone git://github.com/radekp/qtmoko.git cd qtmoko git submodule init git submodule update

• Build the package:

scripts/build-package-gta04.sh

• You might want to stop some services for more RAM:

/etc/init.d/qtmoko-gta04 stop /etc/init.d/bluetooth stop

• You can use ccache - first compilation will be slow but then compiling will be very fast.

Cross compiling without chroot

• This is not supported anymore, but if you know what you are doing you can go on...

• You will need Debian wheezy on your PC

• Install required packages on your host PC:

apt-get build-dep libqt4-dev apt-get install libqt4-dev libv4l-dev libdbus-1-dev libqt4-sql-sqlite

• We will use emdebian toolchain, check this page:

  http://wiki.debian.org/EmdebianToolchain

• Add emdebian apt repos and also sqeeze repos for older packages:

apt-get install emdebian-archive-keyring echo "deb http://ftp.cz.debian.org/debian/ squeeze main contrib non-free" >> /etc/apt/sources.list echo "deb http://www.emdebian.org/debian wheezy main" >> /etc/apt/sources.list apt-get update

• Install armel cross compiler:

apt-get install g++-4.4-arm-linux-gnueabi

• Install xapt and libraries qtmoko depens on:

apt-get install xapt xapt -a armel -m libxext-dev libasound2-dev libdbus-1-dev libssl-dev libts-dev libbluetooth-dev libxtst-dev libpng12-dev libjpeg8-dev libv4l-dev libspeexdsp-dev libglib2.0-dev libsqlite3-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libpulse-dev libvorbis-dev libgps-dev

• Make sure that there is no libqt4 installed in /usr/arm-linux-gnueabi because QtMoko build can link agains that qt-x11 and will not work.

• Make link for dbus.h:

cd /usr/arm-linux-gnueabi/include ln -s dbus-1.0/dbus dbus

• Clone current git tree:

git clone git://github.com/radekp/qtmoko.git

• Initialize and update submodules

cd qtmoko git submodule init git submodule update

• Create build directory (you cant build from the git directory)

mkdir ../build cd ../build

• Build it:

../qtmoko/configure -device neo make make install

• Upload the result to your device (you must have phone and usb network up)

../qtmoko/devices/neo/scripts/update_qtmoko

• If you want translations to various languages you need to checkout the translations git branch:

git checkout origin/translations -b translations

PC build

* It's now possible to build QtMoko for x86 without cross compiling. This
is great for development.

• Create and enter debian chroot:

sudo scripts/qtmoko-chroot-armhf.sh mkdir -p /root/qte/build-pc cd /root/qte/build-pc

• Build it:

../qtmoko/configure -device pc make export LD_LIBRARY_PATH=/root/qte/build-pc/qtopiacore/host/lib/ make install

* To run the image you need to be root and symlink the result image to opt:

cd /opt ln -s /root/qte/build-pc/image qtmoko

* Now switch to first console (CTRL+ALT+F1) and run it:

. /opt/qtmoko/qpe.env qpe

Old way

• Make sure you have installed on your host PC: libqt4-dev, libv4l-dev

• You can also do fetch all build dependecies for qt:

apt-get build-dep libqt4-dev

• Download and install toolchain

cd / sudo wget http://sourceforge.net/projects/qtmoko/files/Toolchain/qtmoko-debian-toolchain-armv4t-eabi.tar.gz/download -O qtmoko-debian-toolchain-armv4t-eabi.tar.gz sudo tar xzvpf qtmoko-debian-toolchain-armv4t-eabi.tar.gz

• If you are on x86_64 you will need to download following 32bit libraries:

libmpfr1ldbl_XXX_i386.deb libgmp3c2_XXX_i386.deb

 and extract the libraries from these package to /usr/lib32

• Clone current git tree:

git clone git://github.com/radekp/qtmoko.git

• Initialize and update submodules

cd qtmoko git submodule init git submodule update

• Create build directory (you cant build from the git directory)

mkdir ../build cd ../build

• Build it:

../qtmoko/configure -force-build-qt -device neo make make install

• Upload the result to your device (you must have phone and usb network up)

../qtmoko/devices/neo/scripts/update_qtmoko

• If you want translations to various languages you need to checkout the translations git branch:

git checkout origin/translations -b translations

Compiling natively on ARM

• You need ARM device with a lot of storage 512MB of RAM (or 256MB + swap)

• Working devices are e.g. N900 or qemu armel buildhost.

• Basic buildhost can be downloaded from here:

http://sourceforge.net/projects/qtmoko/files/BuildHost/

• Install dependencies on build host:

apt-get build-dep libqt4-dev apt-get install libdbus-1-dev libts-dev libbluetooth-dev libasound2-dev

• Get QtMoko sources:

git clone git://github.com/radekp/qtmoko.git

• Initialize and update submodules

cd qtmoko git submodule init git submodule update

• Create build directory (you cant build from the git directory)

mkdir ../build cd ../build

• Build it:

../qtmoko/configure -device neo -xplatform linux-native-g++ -l dbus-1 -I /usr/include/dbus-1.0/ -I /usr/lib/dbus-1.0/include make make install
