Boot to Gecko aims to create a complete, standalone operating system for the open web.

- A 64 bit linux distro
- See http://source.android.com/source/initializing.html on configuring USB access.
- 20GB of free disk space
- autoconf-2.13
- git
- ccache
- gcc/g++ 4.6.3 or older
- bison
- flex
- 32bit ncurses
- 32bit zlib
- make
Additionally, if you're building the emulator, you probably need the the Mesa implementation of OpenGL. On Ubuntu, this is the libgl1-mesa-dev package.
Ubuntu 12.10 ships with gcc 4.7 by default, which causes build errors pretty early in the process. To use gcc 4.6, edit .userconfig and add
export CC=gcc-4.6
export CXX=g++-4.6
Of course, you'll need the g++-4.6 package installed.
- XCode
- 20GB of free space
- homebrew
- git (if not using XCode 4)
- gpg
- ccache
- autoconf-2.13 - brew install https://raw.github.com/Homebrew/homebrew-versions/master/autoconf213.rb
Note: Some B2G subrepositories contain files whose names differ only in case. Amazingly, the build seems to work properly on OSX case-insensitive file systems, despite this. But if you do |./repo status|, you'll see lots of spurrious "modified files" corresponding to these pairs of files whose names differ only in case. Try not to worry about it.
Run config.sh to get a list of supported devices:
./config.sh
And then run config.sh for the device you want to build for:
./config.sh [device name]
If you get "error: insufficient permissions for device"...
Obtain ID of device manufacturer (first 4 hexidecimal digits before colon):
$ lsusb
Add a line to /etc/udev/rules.d/android.rules (replacing XXXX with 4 digit ID):
SUBSYSTEM=="usb", ATTRS{idVendor}=="XXXX", MODE="0666"
Restart udev before re-plugging your device for it to be detected:
$ sudo service udev restart
Re-run configure:
./config.sh [device name]
It can sometimes be useful to build against a different Gecko than the one specified in the manifest, e.g. a mozilla-central checkout that has some patches applied. To do so, edit .userconfig:
GECKO_PATH=/path/to/mozilla-central
GECKO_OBJDIR=/path/to/mozilla-central/objdir-gonk
Note that if you switch your userconfig's gecko path, you need to rm -rf the objdir and rebuild.
Run build.sh or bld.sh to build B2G.
./build.sh
If you want to just build gecko or some other project, just specify it:
./build.sh gecko
Make sure your phone is plugged in with usb debugging enabled.
To flash everything on your phone:
./flash.sh
To flash system/userdata/boot partitions on fastboot phones:
./flash.sh system
./flash.sh boot
./flash.sh user
To update gecko:
./flash.sh gecko
To update gaia:
./flash.sh gaia
To update all repos:
git pull
./repo sync
To update a specific repo (eg, gaia):
./repo sync gaia
To restart B2G and run B2G under gdb:
./run-gdb.sh
To attach gdb to a running B2G process:
./run-gdb.sh attach
To run the Marionette test suite on the emulator:
./test.sh
To run specific tests (individual files, directories, or ini files):
./test.sh gecko/dom/sms gecko/dom/battery/test/marionette/test_battery.py
Specify the full path if you're using a different Gecko repo:
./test.sh /path/to/mozilla-central/dom/battery/test/marionette/test_battery.py
