Cross-building QtMoko on Debian

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

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

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

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

Building QtMoko v36

Configuration

Configuration file for multistrap (/etc/multistrap/armel-sid.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

Configuration file for pdebuild-cross (/etc/pdebuild-cross/pdebuild-cross.rc):

# /etc/pdebuild-cross/pdebuild-cross.rc is the one meant for editing.

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 v36 tag:

$ cd qtmoko
$ git checkout v36

Patch the debian files

$ wget -O - -c http://wiki.openmoko.org/images/0/0a/QtMoko-v36-pdebuild-cross-patch.txt | patch -p1

Building the QtMoko package

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

$ tar czf ../qtmoko_36.orig.tar.gz -C .. --exclude .git --exclude .pc --exclude qtmoko/debian --transform 's:\./qtmoko:qtmoko-36:' ./qtmoko

Build:

$ pdebuild-cross -aarmel

Building QtMoko v35

QtMoko v35 is the trickiest case since it requires a Debian Squeeze pbuilder chroot which misses the xapt tool. Hopefully an official backport will be available soon. For now I use a backport sitting in my own repository.

Configuration

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=

[Toolchains]

reinstall=binutils-multiarch

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

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

This file must be executable (chmod a+x).

Configuration file for pdebuild-cross (/etc/pdebuild-cross/pdebuild-cross.rc):

# this is your configuration file for pdebuild-cross.
# /etc/pdebuild-cross/pdebuild-cross.rc is the one meant for editing.
#
# read pbuilderrc (5) and pdebuild-cross (1) for notes on specific options.

# remember to change CROSSARCH, DEBBUILDOPTS and MULTISTRAPFILE to
# change your target cross-building architecture from armel.

CROSSARCH=armel
DEBBUILDOPTS="-aarmel"
MULTISTRAPFILE=/etc/multistrap/armel-squeeze.conf
#BASETGZ=/var/lib/pdebuild-cross/pdebuild-cross.tgz
BASETGZ=/home/pdebuild-cross.tgz
BUILDPLACE=/var/lib/pdebuild-cross/build/

# Only use when testing Xorg apps, not when building
# also remember to copy ~/.Xauthority into /home/$SUDO_USER/
# (mkdir /home/$SUDO_USER if necessary).
#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

The second step will trigger the xapt installation through the E10-xapt hook script defined above.

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

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

$ pdebuild-cross -aarmel
