I'm new to Objective C.
I've installed jEdit on windows 7 and the gcc compiler too.
I need to know how to use jEdit to develop Objective C applications on windows
Thank you.
You just write the code in jEdit(with .m extension for files) and compile it. If you want to develop iPhone apps, you would have to do some other stuff because it would require extra libraries that's native to Macs. Easiest way would be to get a Mac, or you can look here for some info on doing it in windows:

You'll need an Objective C compiler, plus a set of frameworks like GNUstep. You can get both at http://www.gnustep.org. Work is ongoing, but there's a lot left to do, especially on Windows.

Is there any way to build objective c or iPhone program on Windows 7 ?
or any other software that is same as Xcode.
i does not want to deploy, want to build and test for learning purpose.
i don't want to install Mac OSx using VMware.
You could get objective c compiler on your windows, but i dont think that you will be able to get the cocoa framework on it, so you could be able to learn objective c language but not cocao and cocoa touch

Yes, there are several solutions out there, but the first that comes to mind is RareWire. While you cannot design in objective-c, you can create iPhone apps on any platform that has a web-browser and send them to your device.
Unfortunately, at this time, RareWire is invite-only, so you would have to request an invite to get in.
If it's only for learning purposes with regards to the Objective-C language itself, meaning you don't need the Cocoa API, then gcc has a perfectly fine Objective-C compiler. See for yourself: http://ideone.com/395tl
Is the gnu objective c compiler for windows the same as the compiler for Mac OS X (and Ipad)?
I want to write some code on windows and run it on the mac and ipad, objective C seems to be the best way to go for the Mac/Ipad but is the gnu compiler the same? I know the libraries cocoa etc are not available but this is not an issue we'll be writing different interface code for each platform (please no comments about this is not the right way etc).

The compiler is more or less the same, but the runtime systems are different. If you don’t use the new features from Objective-C 2.0 your code should work fine with both runtime systems. If you want to use the new features you have to use a different runtime. You can find more information here on the GNUstepWiki.
But you still need a framework that provides basic objects like strings, arrays, dictionaries and so on. You could use this part from The Cocotron, a framework that tries to make all of Cocoa available on Windows, Linux and other platforms.
Is Objective C an Apple language or can you run Objective C on other platforms like linux?
Objective-C is not an OS X/iOS specific language, eg. the GCC has its own, non Apple, ObjC runtime that also works on Linux (not sure about LLVM, but I guess they have their own runtime too).
However, the complete library (Cocoa, UIkit, etc) are Apple only. You will have to write your own NSObject and all subclasses if you want to use them (or use the GNUStep library for this).
You can run it on Linux using GNUStep and GCC as the compiler. By the way you will not be able to use a full Cocoa environment as a framework. Have a look at this compatibility list of AppKit
While it's that the language can be compiled and run on multiple other platforms (as others have said), in practice it's almost exclusively used for Mac OS X and iOS development.
Also checkout Cocotron.
Hi just wondering how do you start writing programs for MAC OS X?
what language does it use? can I use objective C? which IDE do I use? any licensing fee should I know about.
Thanks.
Mac OS X is a great programming platform, as such you can use just about any language you like.
If you wish to write native applications using the Cocoa framework you'll probably want to be using Objective-C. You can download XCode as an IDE for free.
No licensing fees.
Xcode is the apple supplied IDE, and without external libraries some objective C is always required to build applications.
That being said xcode supports multiple types of langauges, and has extensions for many more - and C++ can be spliced in with objective C code - so if you prefer to code in C++ you can write a quick objective C wrapper and do all your own stuff in C++ - or indeed the langauge of your choice. There are a few other open source IDE's but I don't really recommend them - most of them crash on opening in new versions of Mac OS X.
Xcode is found in the developer package on your second mac install disk, or the latest version (with iphone SDK's) can be downloaded once registering on the Apple Developer Website, which you can become a basic member of for free.
As far as licensing goes, unless you plan to make a game for iOS there are no liscensing fees, unless you want a full subscription to apples developer website, which gives you a few extra things from them.
If your trying to write a game, consider using the SDL library, a cross platform wrapper for whole lot of operating system interface functions, including graphics - or you can use it as I do in combination with OpenGL for full 3D Support, hardware acceleration, ect.
Objective-C + Cocoa
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/ObjectiveC/Introduction/introObjectiveC.html
http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaFundamentals/Introduction/Introduction.html
Apple suggests XCode
The native libraryfor OS X developed by Apple are called Cocoa. It provides OS X's graphical user interface, and other libraries such as Core Data for database acess, Core Animation for fast easy animation and video features in your software. These libraries are written in a mixture of C and Objective C (which is an extension of the C language). For best performance and best integration with the Mac operating system you should probaby look at developing in C, Objective C and perhaps some C++ as well.
There are some add-on layers that provide acces to the Cocoa libraries from other languages such as Ruby or Python. These are generaly of good quality and work well, so you can use these languages if your aplication does not need the very best performance. They are generaly considered to be easier to learn than the C family of languages and you can become productive very quickly.
Beyond that, you can use languages and toolkits that are platform-independent so your software will can run on Linux or Windows as well as the Mac. For example Python comes with a simple built-in GUI toolkit called Tkinter. You can use more powerful cross-platform toolkits such as Qt or WxWidgets with C or C++ but have excellent bindings for Ruby, Python and other langauges. This is an approach I am using of a project, with Python and Qt.
Others have mentioned Apple's integrated development environemnt (IDE) called XCode. I have only toyed with it, but it looks very powerful for true native development of Cocoa applications.
I'd like to give Objective-C a try in game programming. The problem is I'd need some tools and libraries for this.
First thing that comes into mind I need is the GUI and graphics library.
What choices do I have?
There are Four non Mac implementations of OpenStep/Cocoa type Objective C platforms:
OpenStep/NextStep : Openstep/NeXT support machines only - Discontinued.
p..... can remember name or find it on web - it's out there somewhere ! - Linux
Cocotron - Windows only
GNUStep Linux/Windows
GNUSTep is the way to go for Linux... I mention there others because 2 and 3 are available in source and they can be used to patch holes in code the GNUStep doesn't have and they might.
When it comes to Graphics library - you may have problems because Apple moved away from the old OpenStep APIs and has kept evolving their APIs far faster than the GNUStep people can play catch up. There is no support for the latest graphics libraries such as Core Animation.
As Objective C is C and C++ friendly you can use any of these libraries as is, or by making the Objective C friendly by making a wrapper.
You may or may not want to be Mac compatible and do versions for that so it may not be important.
If you do you might want to do a Linux Wrapper for something like OpenGL if it is missing, which I think it is but have a check yourself....
There are Linux development tools including a project IDE and GUI builder for GNUStep on Linux.

I believe you're asking for GNUStep.
SDL is a C library which is popular for game programming.
If you're looking for Foundation/AppKit stuff you can also look at Cocotron. I've never tried it though.
Supporting SDL there are Objective-C bindings here. However since Objective-C is a thin OO layer on top of C you can use most of the existing C libs for game development, SDL, Clanlib, etc...
