I know objective-c code can be compilied on Windows by gnuStep. GnuStep clone most of the apple libraries but not all. So I am looking smart way find the remaining class since I assume using apple library on other os might be against the apple's licence.(Please don't aswer saying buy mac or wmvare solutions).
Thanks.
For iOS you depend on apple's frameworks (Cocoa Touch et al). They are only available on Mac OS X.
While it is possible, to run OS X on PCs (search for "Hackingtosh"), apple forbids to run it on non-apple hardware in its EULA.

I'm not entirely sure about mac or anything, but what I want to do, is compile my objective-c program, for a mac, but compile it on a windows computer.
Is it possible to do this?
I have already successfully compiled an Objective-C program for windows on windows.
Compilation isn't the problem. Linking is.
You'll need something that can spit mach-o executables.
I'm not aware of an app that can specifically target OS X, but the existence of multiple tool chains that can produce iOS binaries on Windows. They typically require a Mac to do the signing for iOS, but that step is optional when targeting OS X.
If I run this command:
file /System/Library/Frameworks/GameKit.framework/GameKit
I get:
/System/Library/Frameworks/GameKit.framework/GameKit: Mach-O 64-bit
dynamically linked shared library x86_64
Which equates to my iMac (a brand new one) is missing the x86 version of GameKit. So my x86 Mac application (it is a C# Xamarin.Mac app) crashes when referencing GameKit.
Does anyone know if this is going to be an ongoing issue for future Macs? Or is it an Apple bug that this is missing on my machine?
Everything points to Apple deprecating 32-bit (architecture i386) code at some point. This is because they took advantage of switch from 32-bit to 64-bit code to add features to the Objective-C runtime, making 64-bit runtime more featureful.
I have no confirmation for this, but judging from how PowerPC transition was handled, and how 64-bit code deprecates loads of ancient technologies, this is probably not far off.
Although I do have 32-bit GameKit on my machine, it would not surprise me at all if a future release of OS X might contain no 32-bit code. And since all Macs that contain GameKit must be able to run 64-bit code (a requirement for Mountain Lion), the best advice I can give is to add a 64-bit version of the app. I have no idea if MonoMac supports 64-bit code, but that's the direction you should go to.
I suspect an OS update (such as the upcoming 10.8.3) might install a version of GameKit that happens to contain 32-bit code. Or it might remove 32-bit code for the rest of us. But I would absolutely not count on Apple maintaining or adding new features to 32-bit code, precisely because many features that they like (such as ARC or synthesizing ivars) can't be supported by the so-called 32-bit Objective-C runtime without breaking binary compatibility.
am developing one dictionary for mac os 10.6. Am not able to locate glib.h. can i get this as a library or framework. am confused very much. please give me your valuable solution.
Note: i want to use GSList from glib
Install it using MacPorts or download the source code and install manually. Or if you're developing a cocoa aplication I'm sure the framework has it's own list structures, it would be better to use the native ones.

Game programming on Objective-C and linux
I know that developing iPhone apps (painlessly, at least) pretty much requires a Mac. However, is it possible to develop normal desktop applications using Objective-C in Linux? For example, could I make a game using a development library for Objective-C, and release it for Linux, rather than iOS?
There are a lot of normal desktop applications which use GNUstep (free version of Cocoa API) on Linux.
For games you can try sdlobjc — SDL binding for Objective-C.
There is even a Linux distribution called Étoilé which uses GNUstep based user environment and all own GUI applications writen in Objective-C.
If you want to learn how to program in Objective-C using GNUstep on Linux (or cygwin) there are some possible problems:
You must use cygwin in windows to build the application. Which means that it:
a) some applications can be slowed down because of cygwin's translations of POSIX API calls to Win32 API calls. For example fork() call will be translated in Win32's CreateProcess call and some others and will be less efficient than in UNIX.
b) your application must be distributed with cygwin's dll
c) your application can't be 64bit (at least for now)
d) you application will see all your windows disk drives as a part of unix filesystem hierarchy (c: and d: will be /cygdrive/c and /cygdrive/d) and you will have /bin /tmp /usr /etc avialable under / as well.
There's not up-to-date books about GNUstep or about programming Objective-C not using Mac OS. Thre is Stephen Kochan's book "Programming in Objective-C 2.0 (2nd Edition)" where he unfortunately ommits explaination of how to build even basic examples under Linux or Windows. I hope it is fixed in 3rd edition.
GNUstep has own themes so apps may be themed differently than GTK Linux applications in Linux or usual themed application in Windows.

How can I develop for iPhone using a Windows development machine?
(42 answers)
Closed 5 years ago.
I am currently designing and planning an app that I intend to release for iPhone and iPad. I don't currently have a Mac, so I really have no way to actually publish the app, but I don't really want to buy a Mac either just for the development of the app.
Is there any way that I can write (and maybe even test) the app on Windows, then, once I have a finished product, buy a Mac or borrow a friends Mac to publish it.
I know that there is no way to publish to the Apple App Store without a Mac, but I was wondering if there is a way that I could develop and test the app (in Objective-C) on Windows.

No, there is not. XCode is required for iOS development, and it is only available on Mac OS.
You could get a second, cheap hard drive, and install OS X on the hard drive to make your computer into a Hackintosh. You'd need a copy of OS X, and a willingness to break the TOS for the operating system.
This is actually a very frequently asked question, and I'm afraid the answer is no, you cannot do iOS development on Windows.
Back in the iPhone OS 2.0 days there was a cross-compiling framework that did accomplish this but it's abandoned and doesn't work for years now and AFAIK nobody bothered to make it work again (it's a lot of work and requires intimate knowledge about cross-compiling and hunts a constantly moving target).
The usual recommendation is to buy a used Mac Mini since they're cheaply available on sites like eBay.
duskwuff is right to a point... XCode itself is not actually requred in fact there is IDEA's AppCode IDE. Unfortunately, that only runs on OS X. The best thing you can do (other than get a cheap Mac) is install GCC on windows or a Linux VM compile from the command line, as GCC can compile Objective-C. However, that still is not a good solution since you won't have Access to Cocoa Touch and all those calls will error out as undefined or undeclared....
No, you can't. If your going to buy a Mac to publish in the future, why not just buy it now?
You can use OS X in a virtual machine on your windows system. I have read few articles on the internet how to do it using VirtualBox for that (google for it). Even if it's not officially supported by VirtualBox, it's possible. This breaks the TOC for OS X, and you need to buy a copy as well, but VirtualBox is free.
Yes you can!!!
Use virtual box.
Search some guides on "lifehacker.com" about getting mac on virtual box.
It's what I always used before getting a mac.
