Download and Build

System requirements

Listed below are the recommended requirements for downloading and building the SDK:

• CPU: x86_64 or better family processor
• Memory: 8GB or higher
• Disk: 20GB free hard disk space, if you build it in a Virtual machine, I recommand you allocate a 30G virtual hard disk.
  • The Whole SDK is about 15G.
• OS: Ubuntu 14.04 (tested) or higher
• Network: internet connection

Linux host setup

Ubuntu 14.04

HINT: later version should also work.
