Possible to build an IPA file on Linux/Window?

Question

Is it possible to build an IPA file with XCode on a non-Mac OS like Windows or (preferably) Linux and preferably without the use of a VM? If yes, what is required to do so?

I did do a basic search and even posted a question on Apple support forum (forums.developer.apple.com/message/11494#11494). I did not find any recent information on this so hence my question hoping you guys would provide faster answer than Apple.

Answer 1

No.

Building an IPA requires Xcode which requires OS X.
