set up scratchbox
The maemo SDK is based around a tool called scratchbox. This essentially let's you pretend you're not cross compiling. To set it up, Nokia has written a very useful script
wget http://repository.maemo.org/stable/chinook/maemo-scratchbox-install_4.0.sh
sudo chmod a+x ./maemo-scratchbox-install_4.0.sh
sudo ./maemo-scratchbox-install_4.0.sh
sudo /scratchbox/sbin/sbox_adduser <your_user_name> yes
set up maemo chinook sdk
Once you have set up scratchbox, you will need to install the maemo tool chain. Again, Nokia has provided a very useful script to install this for you. Simply accept the defaults and type "I accept" at the appropriate time.
Note: you need to create a new login shell so your user is in the sbox group. you can just log out and log back in
wget http://tablets-dev.nokia.com/4.0/maemo-sdk-install_4.0.sh
sh maemo-sdk-install_4.0.sh
echo "sb-conf select CHINOOK_X86" | scratchbox -s -p
echo "yes | fakeroot apt-get install maemo-explicit" | scratchbox -s -p
echo "sb-conf select CHINOOK_ARMEL" | scratchbox -s -p
echo "yes | fakeroot apt-get install maemo-explicit" | scratchbox -s -p
Build libIDL
The the maemo SDK comes with just about everything required to build mozilla. The one thing that is missing is libIDL. The simplest thing to do is build it:
wget http://ftp.gnome.org/pub/gnome/sources/libIDL/0.8/libIDL-0.8.9.tar.gz
tar -xzvf libIDL-0.8.9.tar.gz
cd libIDL-0.8.9
./configure
make
fakeroot make install
cd ..
Build the the trunk (mozilla 1.9)
Finally, you are ready to build.
export PKG_CONFIG_PATH=/usr/lib/pkgconfig/:/usr/local/lib/pkgconfig/
mkdir moz1.9
cd moz1.9/
cvs -d:pserver:anonymous@cvs-mirror.mozilla.org/cvsroot co mozilla/client.mk mozilla/browser/config
cd mozilla/
cp browser/config/mozconfig .
echo "mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-dir-browser-chinook-armel" >> mozconfig
make -f client.mk pull_all
wget https://bugzilla.mozilla.org/attachment.cgi?id=287745
cat attachment.cgi\?id\=287745 | patch -p1
make -f client.mk build_all
Run It!
To run your build in scratchbox, you'll need to install xephyr. Fortunately if you are on a debian based system, this couldn't be easier. Just run:
sudo apt-get install xserver-xephyr
To start the xephyr server, run the following from the host machine:
Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac -extension Composite
once the xephyr xserver is running, you can launch your build from within scratchbox:
$ scratchbox
[sbox-CHINOOK_ARMEL:~] > export DISPLAY=:2
[sbox-CHINOOK_ARMEL:~] > af-sb-init.sh start
[sbox-CHINOOK_ARMEL:~] > cd moz1.9/mozilla/obj-dir-browser-chinook-armel/dist/bin
[sbox-CHINOOK_ARMEL:~] > GRE_HOME=. ./run-mozilla.sh ./TestGtkEmbed
or
[sbox-CHINOOK_ARMEL:~] > GRE_HOME=. ./run-mozilla.sh ./firefox
Convenient scripts
The following scripts can help speed up the process. You don't even have to start the scratch box shell if you run them with the following commands:
cat buildlibIDL19.sh | scratchbox -s -p
cat buildmoz19.sh | scratchbox -s -p
