Install Qemu

Install the necessary packages:

    sudo apt-get qemu qemu-user-static

Create a new image from scratch

Download the most recent Raspbian version: http://downloads.raspberrypi.org/raspbian_latest
Unpack it:

    unzip 2015-02-16-raspbian-wheezy.zip

Prepare the base image

It will be used for the build environment and the final image.

Add empty space to the image
Edit mount_image.sh and change the IMAGE variable accordingly

    IMAGE='2015-02-16-raspbian-wheezy.img'

Chroot in the image

    sudo ./proper_chroot.sh

Change your user to root (your global variables may be broken)

    su root

The locales may be broken, fix it (remove en_GB.UTF-8 UTF-8, set en_US.UTF-8 UTF-8):

    dpkg-reconfigure locales

In the image, make sure everything is up-to-date, and remove the old packages

    apt-get update
    apt-get dist-upgrade
    apt-get autoremove

Setup two images

Create two separate images: one will be used to build the deb packages that are not available in wheezy

    mv 2015-02-16-raspbian-wheezy.img BUILDENV_2015-02-16-raspbian-wheezy.img
    cp BUILDENV_2015-02-16-raspbian-wheezy.img FINAL_2015-02-16-raspbian-wheezy.img

Build environment specifics

Create a symlink to the build image

    ln -s  BUILDENV_2015-02-16-raspbian-wheezy.img 2015-02-16-raspbian-wheezy.img

Chroot in the image

    sudo ./proper_chroot.sh

Change your user to root (your global variables may be broken)

    su root

Add Wheezy backports source packages to build a poppler version compatible with pdf2htmlEX

    echo 'deb-src http://ftp.debian.org/debian/ wheezy-backports main' >> /etc/apt/sources.list
    apt-get instal debian-keyring debian-archive-keyring
    apt-get update

Get the required build dependencies and the sources

    apt-get build-dep poppler
    apt-get source poppler

Compile the package

    cd poppler-<VERSION>/
    dpkg-buildpackage

At least on Debian 8, you may receive an error about libpoppler-glib-dev missing the gir1.2-poppler requirement; you can ignore it.

Install the packages required by pdf2htmlEX

    apt-get install cmake libfontforge-dev libspiro-dev python-dev default-jre-headless
    cd ..
    dpkg -i libpoppler-dev* libpoppler* libpoppler-private-dev*

Download the sources of pdf2htmlEX (we cannot use anything newer than v0.11 because fontforge>=2.0 is not available)

    wget https://github.com/Rafiot/pdf2htmlEX/archive/KittenGroomer.zip
    unzip KittenGroomer.zip

Compile the package

    cd pdf2htmlEX-KittenGroomer/
    dpkg-buildpackage -uc -b

Get the packages out of the building image (run it outside of the chroot)

    cp /mnt/arm_rPi/libpoppler46_* /mnt/arm_rPi/pdf2htmlex_* deb/

Final image specifics

Change the link to the image

   rm 2015-02-16-raspbian-wheezy.img
   ln -s FINAL_2015-02-16-raspbian-wheezy.img 2015-02-16-raspbian-wheezy.img

Chroot in the image

    sudo ./proper_chroot.sh

Change your user to root (your global variables may be broken)

    su root

Copy the debian packages into the chroot (run it outside of the chroot)

    cp deb/*.deb /mnt/arm_rPi/

Install repencencies required by the project

    apt-get install libreoffice p7zip-full libfontforge1 timidity freepats pmount ntfs-3g unoconv python-pip
    dpkg -i *.deb
    pip install twiggy python-magic

Create the user, make Libreoffice and mtab working on a RO filesystem

    useradd -m kitten
    pushd /home/kitten
    ln -s /tmp/libreoffice
    mkdir .config/
    ln -s /tmp/libreoffice_config .config/libreoffice
    popd
    chown -R kitten:kitten /home/kitten
    ln -s /proc/mounts /etc/mtab

Copy the script to the image

    sudo ./copy_to_final.sh

Exit the chroot

Write the image on a SD card

WARNING: Make sure you write on the right filesystem

    sudo dd bs=4M if=FINAL_2015-02-16-raspbian-wheezy.img of=/dev/<FILESYSTEM>

Run the tests

Make sure to set the filename of the image in tests/run.sh

    sudo ./run_tests.sh
