Recently there have been some questions on why we do not officially support Linux and we only OSX. By terms of Apple's SDK agreement, if you are planning to build an app for IOS, "You are expressly prohibited from separately using the Apple SDKs or attempting to run any part of the Apple Software on non-Apple-branded hardware."
In other words, you should NOT be compiling IOS apps on an Linux machine. It is completely fine if your customer only needs android apps but that is a rare occurrence. That all said, we expect to have an experimental Linux support in the next BETA release coming up for android development.
