[edit] 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.

[edit] 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).

[edit] Creating the pbuilder chroot

As simple as:

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

[edit] 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

[edit] 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

[edit] 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.

[edit] Configuration

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

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).

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

[edit] 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.

[edit] Setting up the git workspace

First clone the QtMoko repo:

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

$ 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

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 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.
