I'm tasked with "porting" a few apps from a Windows environment to various mobile platforms and Mac as well.
I plan on writing MVC patterned apps in which I write as many controllers as I can in some sort of universal library, probably in C or C++. Then writing the views in various choice languages (Objective C, Java, .NET, whatever) for the target OSes.
I've never attempted anything like this before, so my questions are: Is it possible to write and compile one library that can be used on iPhone, Android, Blackberry, Windows and Mac? Is it even wise to try this?
I understand that certain native methods simply won't be available on each platform.
You can create a library whose source code is portable, assuming that you properly abstract away any platform-dependent calls. You can't, however, create such a library, compile it, then use it anywhere; you'll have to compile it for each platform.
