Install prerequisites

if you haven't installed these packages, please do so:

sudo apt-get install build-essential autoconf2.13 libdbus-glib-1-dev

Checkout from hg

Qt support is now available from mozilla-central

hg clone http://hg.mozilla.org/mozilla-central

Install Qt 4 (desktop Ubuntu)

Note Qt 4.4 is now available for ubuntu 8.04 if you enable backports in software sources.

sudo apt-get install libqt4-core libqt4-gui libqt4-dev

Install Qt 4.4 (maemo device/scratchbox)

Note: These instructions are for the Chinook (N800) build system, which is what we currently use - if you are building with the more recent Fremantle (N910) build system you should instead follow the Ubuntu/PC instructions above.

echo "deb http://repository.maemo.org/extras-devel diablo free non-free" >> /etc/apt/sources.list
apt-get update
apt-get install libqtcore4 libqtgui4 libqt4-network

For building in scratchbox you also need

apt-get install libqt4-dev

Install additional headers (desktop Ubuntu)

You might need some more development packages installed for configure to succeed.

sudo apt-get install libasound-dev libglib1.2-dev libidl-dev

mozconfig

Here is a sample mozconfig

mk_add_options MOZ_CO_PROJECT=browser,xulrunner

ac_add_options --enable-application=browser

ac_add_options --enable-default-toolkit=cairo-qt
ac_add_options --enable-debug="-g3"
ac_add_options --disable-optimize
ac_add_options --enable-tests

ac_add_options --disable-installer
ac_add_options --disable-crashreporter
ac_add_options --disable-javaxpcom
ac_add_options --disable-printing
ac_add_options --disable-embedding-tests
ac_add_options --disable-elf-dynstr-gc

mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/../obj-qt
mk_add_options MOZ_MAKE_FLAGS=-j4

For arm you may need to disable jemalloc as the compiler doesn't seem to like it

ac_add_options --disable-jemalloc

Build

Build as normal with

make -f client.mk build

I had a build error on Kubuntu 8.10 with Qt4.5 with an #include "qcms.h" not found. I solved it with this patch:

ubu8:~/development/mozilla-central$ hg diff

Custom Qt build

If your are using your own build of Qt you will need to add a line like this to our mozconfig:

ac_add_options --with-qtdir="/usr/local/Trollteh/Qt-4.4.0-rc1"

and set environment vars like this:

export PKG_CONFIG_PATH=/usr/local/Trolltech/Qt-4.4.0-rc1/lib/pkgconfig/
export LD_LIBRARY_PATH=/usr/local/Trolltech/Qt-4.4.0-rc1/lib/
export PATH=/usr/local/Trolltech/Qt-4.4.0-rc1/bin:$PATH
