Prepare Mozilla source tree with Embedding IPC patches and HONK (plain linux port)
Clone mozilla repository + patch queue (for IPC Embedding), better to create some folder like /build

<pre>
mkdir /build
cd /build
hg clone http://hg.mozilla.org/mozilla-central
cd mozilla-central
hg clone http://hg.mozilla.org/users/romaxa_gmail.com/embedipc_queue .hg/patches
hg update `cat .hg/patches/changeset`
hg qpush -a

</pre>

Mozilla toolkit-Xlib-less HONK port, b2g, for rendering into Framebuffer

<pre>
# Install main Mozilla B2G Honk port base dependencies
apt-get install libfreetype6-dev:armel libfontconfig1-dev:armel libasound-dev:armel libudev-dev:armel

# X deps (only for X build)
apt-get install libasound2-dev:armel libxt-dev:armel libxext-dev:armel

# This part is basically enough to build honk (plain linux gecko port ab be able to run it on Framebuffer or SGX EGL fb context)
cd mozilla-central
MOZCONFIG=$(pwd)/.hg/patches/mozconfig.cross.oneiric-honk make -f client.mk build_all

To launch b2g clone and copy https://github.com/andreasgal/gaia to your local PC apache /var/www folder or put it into device /var/www folder
Copy b2g stub to device
cp -rfL obj-build-linaro-honk/dist/bin ./b2g-build
arm-linux-gnueabi-strip ./b2g-build/*
scp -r ./b2g-build/ root@device-ip:/opt
on device:
cd /opt/b2g-build
B2G_HOMESCREEN=http://server[local-server]/gaia/homescreen.html ./b2g

Qt build with X

<pre>

# Install main Mozilla Qt port dependencies
apt-get install libqt4-dev:armel libqt4-opengl-dev:armel libpango1.0-dev:armel libdbus-glib-1-dev:armel libasound2-dev:armel libxt-dev:armel mesa-common-dev:armel

# make sure that required build libraries are still in the system
apt-get install pkg-config unzip zip autoconf2.13 libglib2.0-dev 

# XXX Minor trick in order to get host version of qt moc/rcc
# install host qt-dev version, and backup moc/rcc/uic
apt-get install libqt4-dev
cp /usr/bin/moc-qt4 /tmp/
cp /usr/bin/rcc /tmp/
cp /usr/bin/uic-qt4 /tmp/

# install armel version back
apt-get install libqt4-dev:armel libqt4-opengl-dev:armel

# and replace arm version of moc/uic/rcc
cp /tmp/moc-qt4 /usr/bin/moc-qt4
cp /tmp/rcc /usr/bin/rcc
cp /tmp/uic-qt4 /usr/bin/uic-qt4
