Cross-building QtMoko on Debian

It is possible to cross-build QtMoko on a Debian box using only (em)debian tools.

Tools needed

The builds are done the Debian way, using pbuilder on a Debian Wheezy box. Most of the magic is handled by the pdebuild-cross package:

$ sudo apt-get install pdebuild-cross

Building QtMoko v35

QtMoko v35 is the trickiest case since it requires a Debian Squeeze pbuilder chroot which misses the xapt tool. Hopefully a backport will be available soon.

Configuration

The toolchain comes from the Emdebian project and is set up via the multistrap package (pulled in by pdebuild-cross).

Configuration file for multistrap (/etc/multistrap/armel-squeeze.conf):

[General]
arch=
directory=
# same as --tidy-up option if set to true
cleanup=true
# same as --no-auth option if set to true
# keyring packages listed in each debootstrap will
# still be installed.
noauth=false
# whether to add the /suite to be explicit about where apt
# needs to look for packages. Default is false.
explicitsuite=true
# extract all downloaded archives (default is true)
unpack=true

omitrequired=false
configscript=
setupscript=/usr/share/multistrap/setcrossarch.sh
debootstrap=Debian Toolchains
aptsources=Debian Toolchains
tarballname=pdebuild-cross.tgz

[Toolchains]
packages=g++-4.4-arm-linux-gnueabi linux-libc-dev-armel-cross
reinstall=binutils-multiarch
source=http://www.emdebian.org/debian
keyring=emdebian-archive-keyring
suite=squeeze

[Debian]
packages=dpkg-dev binutils-multiarch build-essential makedev wget
source=http://ftp.fr.debian.org/debian
keyring=debian-archive-keyring
suite=squeeze
omitdebsrc=false

You may also want to change the Debian mirror URIs in to use one near your location. I use a french one.

Hook file for multistrap so that it installs the xapt backport for squeeze from my repository (/etc/multistrap/armel-squeeze-hooks/E10-xapt):

#!/bin/sh
set -e
if [ ! -f /usr/bin/xapt ]; then
  wget http://pini.free.fr/debian/pool/main/e/emdebian-crush/xapt_2.2.17~stable_all.deb
  dpkg -i xapt_2.2.17~stable_all.deb || apt-get -f -y install
  rm xapt_2.2.17~stable_all.deb
fi

#BINDMOUNTS="/tmp"

You may want to change the BUILDPLACE path as well in case you're short of space in /var.

Creating the pbuilder chroot

As simple as:

$ sudo pdebuild-cross-create
$ sudo pdebuild-cross-update

Setting up the git workspace

First clone the QtMoko repo:

$ git clone --recursive git://github.com/radekp/qtmoko.git

Check out the v35 tag:

$ cd qtmoko
$ git checkout v35

Patch the debian files

$ wget -O - -c http://wiki.openmoko.org/images/f/f6/QtMoko-v35-pdebuild-cross-patch.txt | patch -p1

Building the QtMoko package

Create the orig tarball (once after each git merge):

$ tar czf ../qtmoko_35.orig.tar.gz -C .. --exclude .git --exclude .pc --exclude qtmoko/debian --transform 's:\./qtmoko:qtmoko-35:' ./qtmoko

Build:

$ pdebuild-cross -aarmel

On my Zotac ZBox (amd64) the whole build takes just less than five hours.
