-## Prerequisites
+or Telegram:
-### Linux
+ https://telegram.me/B2GOS
-* 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
-* zlib
- * You need both zlib1g and zlib1g-dev for both i386 and amd64. That is, for
- Ubuntu 12.04 Precise or older, they are zlib1g, zlib1g-dev, zlib1g:i386, and
- zlib1g-dev:i386; for Ubuntu 12.10 Quantal or newer, they are zlib1g:amd64,
- zlib1g-dev:amd64, zlib1g:i386, and zlib1g-dev:i386.
-* 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.
-
-On Ubuntu 13.04, for example, you might find `apt-get install zlib1g{,-dev}:i386`
-is going to do something seriously wrong like removing all your toolchain
-packages. You may execute either `apt-get install --no-install-recommends <packages>`
-to explicitly disallow installing recommended packages, or `aptitude` to
-interactively select the very necessary packages you need.
-
-For full lists of minimum required packages that build B2G emulator on all
-recent Ubuntu releases, see https://bugzilla.mozilla.org/show_bug.cgi?id=866489 .

-### OSX
-
-* XCode
-* 20GB of free space
-* homebrew
- * git (if not using XCode 4)
- * gpg
- * ccache

-#### Note: Builds for some devices require case-sensitive file systems
-
-Some B2G subrepositories contain files whose names differ only in case.
-This causes build failures when building for some target phones (such as the
-Hamachi) if you're on a case-insensitive FS (the default on Mac). You'll see
-an error like the following during the ./build.sh step:
-
-> [entering kernel]
-> ERROR: You have uncommited changes in kernel
-> You may force overwriting these changes
-> with |source build/envsetup.sh force|
->
-> ERROR: Patching of kernel/ failed.
-
-If you hit this error, the easiest way around it is to build on a
-case-sensitive file-system. Doing so doesn't require any re-partitioning; you
-can simply create a disk image and build within it using the following
-commands.
-
- hdiutil create -volname 'firefoxos' -type SPARSE -fs 'Case-sensitive Journaled HFS+' -size 40g ~/firefoxos.sparseimage
- open ~/firefoxos.sparseimage
- cd /Volumes/firefoxos/
-
-See https://bugzilla.mozilla.org/show_bug.cgi?id=867259 for details.
-
-#### Note: Linker OOM with noopt builds
-
-If you build with B2G_NOOPT=1 on MacOS, your linker may run out of memory and
-crash.
-
-The solution, if you really want a noopt build, is to use a 64-bit linker.
-Follow these steps:
-
-1. Clone this repository somewhere
-
- $ git://github.com/jld/b2g-toolchain-prebuilt.git
-
-2. In .userconfig, add the following line.
-
- export TARGET_TOOLS_PREFIX=/path/to/b2g-toolchain-prebuilt/toolchain-4.4.3/x86_64-apple-darwin/bin/arm-linux-androideabi-
-
- (Of course, replace /path/to/b2g-toolchain-prebuilt/ with the actual path.)
-
-3. Rebuild.
-
-See https://bugzilla.mozilla.org/show_bug.cgi?id=854535 for details.
-
-## Configure
-
-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]
-
-### Udev Permissions
-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]
-
-### Building against a custom Gecko
-
-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.
-
-## Build
-
-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
-
-## Flash/Install
-
-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
-
-## Update Repos
-
-To update all repos:
-
- git pull
- ./repo sync
-
-To update a specific repo (eg, gaia):
-
- ./repo sync gaia
-
-## Debug
-
-To restart B2G and run B2G under gdb:
-
- ./run-gdb.sh
-
-To attach gdb to a running B2G process:
-
- ./run-gdb.sh attach <PID>
-
-## Test
-
-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
