Downloading WebRTC using Ubuntu

Hi,


This post explains the basic steps that one needs to follow for downloading WebRTC code base using Ubuntu.

My Ubuntu Virtual Box configurations are - 
Linux vm2 3.19.0-28-generic #30~14.04.1-Ubuntu SMP Tue Sep 1 09:32:55 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux



The main steps are.

• mkdir webrtc-checkout  // Create a new folder
• cd webrtc-checkout
• sudo apt-get install git
• git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git   // A folder named depot_tools will be created in your current directory
• export PATH=/home/rohit/webrtc-checkout/depot_tools:"$PATH"  // Add depot_tools  to the PATH
• sudo apt-get install g++ python libnss3-dev libasound2-dev libpulse-dev libjpeg62-dev libxv-dev libgtk2.0-dev libexpat1-dev  // Necessary packages
• apt-get install openjdk-7-jdk  // It gets installed in /usr/lib/jvm/java-7-openjdk-amd64
• export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64
• fetch --nohooks webrtc  // After this if you use 'ls -la' we can see .gclient_entries, .gclient and src (these are newly created)

• gclient sync  // This will take several hours to complete as the total code size is in gigabytes

More details are available official links of WebRTC

It is better not to use a Virtual Machine, as it may give several issues and in the end code downloading will get stopped.  So it is better to use a seperate linux PC.
