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 de 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

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

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

# 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.

# 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

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.

Personal tools

Cross-building QtMoko on Debian

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

This is a work in progress. The resulting package isn't fully functionnal yet:

  • no sound
  • no bluetooth.

Tools needed

Most of the magic is handled by the pdebuild-cross package:

$ sudo apt-get install pdebuild-cross

Configuration

The toolchain comes from the Emdebian project. Two configuration files from the multistrap package (pulled in by pdebuild-cross) are needed. It is best to copy them because they're not part of /etc:

$ sudo mkdir /etc/multistrap
$ sudo cp /usr/share/multistrap/{armel,crosschroot}.conf /etc/multistrap

Then modify the armel.conf file to use the Squeeze toolchain (with g++-4.4; the Lenny toolchain with g++-4.2 doesn't work for QtMoko) and to load our copy of crosschroot.conf:

[General]
include=/etc/multistrap/crosschroot.conf
omitrequired=false
configscript=
setupscript=/usr/share/multistrap/setcrossarch.sh
debootstrap=Debian Base 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

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

# Example multistrap configuration file for a sid build chroot
# Need to use cascading to select the toolchain for a cross arch.

[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
# the order of sections is not important.
# the debootstrap option determines which repository
# is used to calculate the list of Priority: required packages.
debootstrap=Debian Base
aptsources=Debian Base

# Lenny toolchains need -base from Lenny.
[Base]
packages=gcc-4.2-base
source=http://ftp.fr.debian.org/debian
keyring=debian-archive-keyring
suite=lenny
omitdebsrc=false

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

Finally update the MULTISTRAPFILE variable in your pdebuild-cross' configuration file (/etc/pdebuild-cross/pdebuild-cross.rc) to point to your multistrap armel config:

# 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=/home/pini/debian/multistrap/armel.conf
BASETGZ=/var/lib/pdebuild-cross/pdebuild-cross.tgz
BUILDPLACE=/var/lib/pdebuild-cross/build/
BUILDRESULT=..
APTCACHE=/var/lib/pdebuild-cross/aptcache/
#HOOKDIR=/usr/share/pdebuild-cross/hookdir/
APTCACHEHARDLINK=no
PBUILDERSATISFYDEPENDSCMD=/usr/sbin/embuilddeps
PBUILDERSATISFYDEPENDSOPT="-m -a armel"
USEDEVPTS=yes
AUTO_DEBSIGN=no

# 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

Setting up the git workspace

First clone the QtMoko repo:

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

Create your own branch:

$ cd qtmoko
$ git branch <my branch>

Merge in the translations branch:

$ git merge origin/translations

Patch the debian files

$ wget -c http://wiki.openmoko.org/images/c/c7/QtMoko-pdebuild-cross-patch.txt
$ patch -p1 < QtMoko-pdebuild-cross-patch.txt

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

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