Mobile/Build/Maemo Build Instructions
Setting Up Scratchbox
The maemo SDK is based around a tool called scratchbox. Scratchbox is a sandboxed emulator that you run on a fast development machine to configure, compile and run (test) the binaries that are to be installed on a target mobile device. It eliminates a lot of the difficulties associated with traditional cross compilation by essentially letting you pretend you're not cross compiling. To set it up, Nokia has written a very useful script called maemo-scratchbox-install.
These instructions are for setting up a new scratchbox installation. If you have an existing (i.e. 3.2/bora) scratchbox installation, you'll have to set an alternate path for the installation.
Debian-based Linux distributions
Scratchbox will be installed by default from Debian .deb packages to the path /scratchbox
wget http://repository.maemo.org/stable/chinook/maemo-scratchbox-install_4.0.1.sh
sudo chmod a+x ./maemo-scratchbox-install_4.0.1.sh
sudo ./maemo-scratchbox-install_4.0.1.sh
sudo /scratchbox/sbin/sbox_adduser $USER yes
Replace $USER with an explicit user name if you want to create a scratchbox login for a user other than the current user.
Other Linux distributions
On any other Linux distribution, the install will use .tar.gz files and you will have to specify the desired destination directory.
wget http://repository.maemo.org/stable/chinook/maemo-scratchbox-install_4.0.1.sh
sudo chmod a+x ./maemo-scratchbox-install_4.0.1.sh
sudo ./maemo-scratchbox-install_4.0.1.sh -s /scratchbox
sudo /scratchbox/sbin/sbox_adduser $USER yes
Again, replace $USER with an alternative user name if you like.
Setting Up the Maemo Chinook SDK
Before you proceed with installing the Maemo SDK, you need to create a new login shell so that your user is added to the sbox group that was created when you installed scratchbox. You can do this by just logging out and logging back in again (that means log out of your machine -- creating a new terminal window will NOT work).
To set up the Maemo SDK, Nokia has provided another easy to use script. You can just accept the defaults and type "I accept" at the appropriate time, but if you want to debug your code you should select the 4th option on the "Package Selection" menu. You will also want to install "Closed Nokia Binaries".
Warning: if you are running Ubuntu Hardy Heron (8.04), read this before you proceed any further. You'll need to run both these commands to be able to install the Maemo SDK.
To install the Maemo SDK onto your host machine run:
wget http://tablets-dev.nokia.com/4.0.1/maemo-sdk-install_4.0.1.sh
chmod +x maemo-sdk-install_4.0.1.sh
bash maemo-sdk-install_4.0.1.sh
[Note: Maemo bora (3.0) is seemed incompatible because the file gtk+-unix-print-2.0.pc seems missing in Bora.]
Selecting a Scratchbox Target
TODO: say something about targets here.
To select the x86 target, run:
echo "sb-conf select CHINOOK_X86" | scratchbox -s -p
or for the ARMEL target, run:
echo "sb-conf select CHINOOK_ARMEL" | scratchbox -s -p
Note:' if you see this:
sb-conf: You must close your other Scratchbox sessions first
You should:
run sb-menu
go to killall
and send a 9
Building 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, run these commands in the scratchbox prompt:
sb-conf se CHINOOK_X86 # because the release still cannot run on ARMEL
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 ..
Building the Trunk (Mozilla 1.9)
Finally, you are ready to build. Run these commands at the scratchbox prompt.
sb-conf se CHINOOK_X86
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
echo "ac_add_options --disable-tests" >> mozconfig
make -f client.mk pull_all
make -f client.mk build_all
Running your Build
To run your build in scratchbox, you'll need to install xephyr from your host machine (i.e. outside scratchbox). Fortunately, if you are on a Debian based system such as Ubuntu, 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 (outside scratchbox):
Xephyr :2 -host-cursor -screen 800x480x16 -dpi 96 -ac -extension Composite
Once the xephyr xserver is running, it will open a window that can be used to display your build. Run your build by logging into scratchbox and then running the following commands:
sb-conf select CHINOOK_X86
export DISPLAY=:2
af-sb-init.sh start
cd moz1.9/mozilla/obj-dir-browser-chinook-armel/dist/bin
GRE_HOME=. ./run-mozilla.sh ./TestGtkEmbed # this is not yet runnable
or
GRE_HOME=. ./run-mozilla.sh ./firefox
Convenient scripts (NOT UP TO DATE. Please use the instructions above.)
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 buildlibIDL.sh | scratchbox -s -p
cat buildmoz19.sh | scratchbox -s -p
VMWare Image
Alternatively, you can download this VMWare image which has already been set up to build mozilla for maemo.
