== Prepare multiarch chroot ==
== Build crosstool-ng toolchain ==


Install crosstool-ng using this tutorial:
http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi
In addition to step 13. enable C++<br/>
And choose compiler linaro-4.7-2013.01<br/>
Tested crosstool-ng config available here:<br/>

Build Qt Mozilla for Raspberry Pi

Build crosstool-ng toolchain

Install crosstool-ng using this tutorial: http://www.bootc.net/archives/2012/05/26/how-to-build-a-cross-compiler-for-your-raspberry-pi

In addition to step 13. enable C++
And choose compiler linaro-4.7-2013.01
Tested crosstool-ng config available here:
http://romaxa.info/raspberrypi/rasp-armhf-whz-4.7-config

Prepare target wheezy armhf chroot

Download raspbian public key from root

sudo su
wget http://archive.raspbian.org/raspbian.public.key;apt-key add raspbian.public.key
CTRL^D

sudo apt-get install qemu-user-static

Debootstrap wheezy chroot

export CHROOTPATH=$HOME/wheezy-armhf
export CHROOTPREFIX=whrp
mkdir -p $CHROOTPATH/usr/bin
cp -rf /usr/bin/qemu-arm-static $CHROOTPATH/usr/bin
sudo debootstrap --verbose --arch=armhf --keyring /etc/apt/trusted.gpg  --include=apt  wheezy $CHROOTPATH http://archive.raspbian.org/raspbian

sudo cp /usr/bin/qemu-arm-static $CHROOTPATH/usr/bin/
sudo cp -f /etc/apt/apt.conf $CHROOTPATH/etc/apt/
sudo cp -f /etc/apt/apt.conf.d/* $CHROOTPATH/etc/apt/apt.conf.d/
sudo cp -f /etc/resolv.conf $CHROOTPATH/etc/
sudo cp -f /etc/hosts $CHROOTPATH/etc/

Install required packages inside chroot

sudo chroot $CHROOTPATH apt-get update
sudo chroot $CHROOTPATH apt-get install -y --force-yes sudo adduser python2.7 bash-completion

make chroot alias

echo "alias o"$CHROOTPREFIX"chroot='sudo chroot $CHROOTPATH su - '" >> ~/.bashrc
 . ~/.bashrc

Make chroot shell different from host

echo "PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]-"$CHROOTPREFIX":\[\033[01;34m\]\w\[\033[00m\]\$ '" >>  $CHROOTPATH/root/.bashrc

Make sure that proc mounted in order to avoid some warnings

echo "sudo mount -t proc proc /proc" >> $CHROOTPATH/root/.bashrc

fix undefined locale warnings, and enable bash completion

echo "
export LANGUAGE=C
export LC_ALL=C
export LANG=C
if [ -f /etc/bash_completion ]; then
   . /etc/bash_completion
fi
" >> $CHROOTPATH/root/.bashrc

Setup Scratchbox 2 around installed toolchain and dev rootfs

# Install sbox2 with:

sudo apt-get install scratchbox2

# or use these instructions:
# http://russelldavis.org/2011/09/07/setting-up-scratchbox2-from-scratch-for-the-raspberry-pi/

# also small hack around: error "Never use <bits/predefs.h> directly; include <stdc-predef.h> instead."
sudo cp /opt/cross/x-tools/arm-unknown-linux-gnueabi/arm-unknown-linux-gnueabi/sysroot/usr/include/features.h $CHROOTPATH/usr/include

Initialize sb2 config

cd $CHROOTPATH
sb2-init Raspi /opt/cross/x-tools/arm-unknown-linux-gnueabi/bin/arm-unknown-linux-gnueabi-gcc
sb2-config -d Raspi

Build Qt-Mozilla inside chroot

Install Qt dev packages to Dev rootfs

# Core dependencies (--enable-default-toolkit=linuxgl)
sudo chroot $CHROOTPATH apt-get install -y --force-yes libpango1.0-dev libasound-dev libfreetype6-dev libffi-dev
# Qt dependencies (--enable-default-toolkit=cairo-qt)
sudo chroot $CHROOTPATH apt-get install -y --force-yes libqt4-dev libqt4-opengl-dev libxt-dev libx11-dev libxext-dev
# Gtk dependencies (--enable-default-toolkit=cairo-gtk2)
sudo chroot $CHROOTPATH apt-get install -y --force-yes libgtk2.0-dev

Clone Mozilla-Central and build

mkdir ~/build && cd ~/build
hg clone http://hg.mozilla.org/mozilla-central

cd mozilla-central
# Apply configure hacks for crosstool-ng toolchain problems, probably could be fixed with better configuration of cross-toolchain
