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 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 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 dpkg-cross source=http://ftp.fr.debian.org/debian keyring=debian-archive-keyring suite=unstable omitdebsrc=false
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.

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 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/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/ BUILDRESULT=.. APTCACHE=/var/lib/pdebuild-cross/aptcache/ HOOKDIR=/etc/multistrap/armel-squeeze-hooks 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 $ 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
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.
