Build native webrtc project

build_webrtc

The webrtc build instruction is very shitty in my opinion. It has way too much confusing information that is unrelated to webrtc.

here are the steps I went through to build it on ubuntu:

1. install tools:
  git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
  $ export PATH=`pwd`/depot_tools:"$PATH"

2. sync code:
  gclient config --name src http://webrtc.googlecode.com/svn/trunk
  gclient sync --force

3. set JAVA location:
  export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64

4. install missing dependencies:
  sudo apt-get install libnss3-dev
  sudo apt-get install libgnome-keyring-dev
  sudo apt-get install libgconf2-dev
  sudo apt-get install libxss-dev
  sudo apt-get install libxtst-dev
  sudo apt-get install libudev-dev
  sudo apt-get install libpci-dev
  sudo apt-get install libasound2-dev
  sudo apt-get install libpulse-dev

5. build:
  gclient runhooks --force
  cd src/
  ninja -C out/Debug/
  ninja -C out/Release/
