Download and Build
Prebuilt Image
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
Lazy Start
Linux host setup
Ubuntu 14.04
HINT: later version should also work.
