The official versions of the Tizen 1.0 SDK currently run only on Ubuntu 10.04/10.10/11.04/11.10 32-bit and Windows XP SP3/7 32-bit. Several developers, during the recently concluded developer conference, were asking for a 64-bit version. While there were hints that it can be done on Ubuntu, there has not been any detailed instructions on how to do it until now.
After a lot of trial and error, Tomi Ollila has managed to install the Tizen 1.0 SDK on a 64-bit Fedora 16. The detailed step-by-step instructions can be found at Nixu Open’s blog. On the same blog entry, Michael Przybilski has commented that changing a few items in the instructions will let you install the SDK to Ubuntu 12.04 – Precise Pangolin, on top of 64 bit Debian / Wheezy.Source: Nixu Open
