WebKit Apocrypha

If we would like to build WebKitGTK+ for ARM platform, Scratchbox could be a good choice. In this post I will show, how we can install and setup Scratchbox to build WebKitGTK+. First, we have to install the Scratchbox and its ARM target. Next, we install some libraries to WebKitGTK+.
Let's see how we can do that.

Installing Scratchbox

There are two scripts that will install the Scratchbox and the Maemo SDK.

• maemo-scratchbox-install_4.1.2.sh
• maemo-sdk-install_4.1.2.sh

Download the scripts:

$ wget http://repository.maemo.org/stable/diablo/maemo-scratchbox-install_4.1.2.sh
$ wget http://repository.maemo.org/stable/diablo/maemo-sdk-install_4.1.2.sh
$ chmod a+x ./maemo-scratchbox-install_4.1.2.sh
$ chmod a+x ./maemo-sdk-install_4.1.2.sh

Install the Scratchbox and add a user:

$ sudo ./maemo-scratchbox-install_4.1.2.sh -s ~/scratchbox
$ sudo ~/scratchbox/sbin/sbox_adduser arm-user yes

Install the Maemo SDK on Scratchbox: (ARMEL and x86 targets)

$ ./maemo-sdk-install_4.1.2.sh -s ~/scratchbox -d

Now, our Scratchbox is ready for use.
We can stop and start it with the following commands:

$ sudo ~/scratchbox/sbin/sbox_ctl stop
$ sudo ~/scratchbox/sbin/sbox_ctl start

Installing the libs

To build WebKitGTK+, we have to install several libraries. Some libraries can be installed using apt-get, but some others are pretty new and we have to install them manually.

First we need a newer autotools: (outside Scratchbox)

$ cd ~/scratchbox/tools/autotools/autoconf2.61
$ sudo cp -fr --remove-destination * ../../

$ cd ~/scratchbox/tools/autotools/automake-1.9
$ sudo cp -fr --remove-destination * ../../

Now it's time, to login to Scratchbox: (the default target is the DIABLO-ARMEL)

$ ~/scratchbox/login
[sbox-DIABLO_ARMEL: ~] _

Add these new sources to the sources.list of apt: (/etc/apt/sources.list)

deb http://repository.maemo.org/extras/ diablo free non-free
deb-src http://repository.maemo.org/extras/ diablo free
deb http://repository.maemo.org/extras-devel/ diablo free non-free
deb-src http://repository.maemo.org/extras-devel/ diablo free
deb http://repository.maemo.org/ diablo sdk/free sdk/non-free tools/free tools/non-free
deb-src http://repository.maemo.org/ diablo sdk/free sdk/non-free tools/free tools/non-free

Next, update, upgrade and install some packages:

[sbox-DIABLO_ARMEL: ~] > fakeroot apt-get update
[sbox-DIABLO_ARMEL: ~] > fakeroot apt-get upgrade
[sbox-DIABLO_ARMEL: ~] > fakeroot apt-get install gperf gtk-doc-tools libicu-dev libenchant-dev \
 libgail-dev libxslt1-dev gnome-doc-utils

As I said, some new libraries are not available via apt-get so lets do the final steps manually:

[sbox-DIABLO_ARMEL: ~] > wget http://ftp.gnome.org/pub/gnome/sources/glib/2.22/glib-2.22.2.tar.gz

[sbox-DIABLO_ARMEL: ~] > cd pixman-0.10.0
[sbox-DIABLO_ARMEL: ~] > ./configure --prefix=/usr

[sbox-DIABLO_ARMEL: ~] > cd cairo-1.6.0
[sbox-DIABLO_ARMEL: ~] > ./configure --prefix=/usr
[sbox-DIABLO_ARMEL: ~] > make && make install

Building WebKitGTK+

Now our Scratchbox environment is ready to build WebKitGTK+. Checkout WebKit and build:

[sbox-DIABLO_ARMEL: ~] > svn checkout http://svn.webkit.org/repository/webkit/trunk WebKit
[sbox-DIABLO_ARMEL: ~] > cd WebKit
[sbox-DIABLO_ARMEL: ~] > WebKitTools/Scripts/build-webkit --gtk

Enjoy your fresh WebKitGTK+ on ARM! :)
