Is there a library out there that allows developers to register and handle custom URI schemes on Windows, OS X, and maybe Linux?
I found URISchemeHandler on GitHub, which is written in Java, but it does not support OS X. I could fork it and try to implement it myself, but I don't own a Mac, so I wouldn't be able to test it properly.

I have a very specific question. I want to create a multimedia multi-platform application on C# which will use Mono. Is it possible to create a C# Mono application which will use gstreamer-sharp or "pure" gstreamer or something like "glued" gstreamer on these platforms: Windows, Mac OS, Linux, iOS, Android? I think I can use Pinvoke, but maybe it can be implemented more elegant? I know, it's maybe really strange question(or maybe not ;-)) but which variants I have?
This should be do-able. The gstreamer SDK is available for all of your required platforms and is documented/can be installed from here:

I have a plan to build a web-site which running CGI made with Cocoa.
My final goal is develop on Mac OS X, and run on FreeBSD.
Is this possible?
As I know, there is a free implementation of some NextStep classes, the GNUStep.
The web-site is almost built with only strings. I read GNUStep documents, classes are enough. DB connection will be made with C interfaces.
Most biggest problem which I'm concerning is linking and binary compatibility. I'm currently configuring FreeBSD on VirtualBox, but I wanna know any possibility informations about this from experts.
This is not a production server. Just a trial. Please feel free to saying anything.
--edit--
I confused Foundation and Cocoa frameworks. What I said was Foundation. Basic classes which just enough to manipulating strings.
It’s entirely possible to cross-develop using Xcode. The Cocotron does this – and provides an implementation of Foundation – but doesn’t currently target FreeBSD. You could probably use it as a template to set up cross-development for BSD targets using GNUstep, but it won’t be easy.
You should be OK with the GNUstep Foundation on FreeBSD 9.0 with Objective-C 2 (clang). See these instructions.
Note: Do not installing under '/' with a FreeBSD default install, because it has little space on the '/' partition. I've used /usr/local/gnustep instead, and made some links as the instructions suggest.
Note II: GNUstep sources from subversion repository didn't compile for me, so I used the latest stable GNUstep sources.
Yes, you can do this, and I am doing it right now successfully using FreeBSD 8.2 and Xcode 4.0, running the Foundation class from The Cocotron. Here is a link: describing exactly what I did to build the cross compiler and set everything up. I also detail in that post, how I attempted to get AppKit (GUI) to work. I failed, it may work in the future, it doesn't fully work yet.
So far it's great. I use a common codebase to write iPhone App (game client) and FreeBSD Game Server; after my server compiles I even have a target rsync the files to my dev box.
One more note, you mention DB, I'm successfully using mysqlclient libraries within my App and my post details how to do that. Since you're building a cross-compiler with The Cocotron you can use any library. Just install the library on FreeBSD first, then create the platform as described.
Sounds like your trying to shoehorn tools onto OS and hardware they were not designed for. There are hacks to get almost anything running on top of anything else but why ask for all the grief?
The entire point of the entire Apple API is that you have integration from hardware to OS to development tools. You supposed to pay more up front in return for greater robustness and lower over all lifecycle cost. (It doesn't always work just like Linux doesn't always save money and Windows doesn't always provide the software choices you need but that is the design goal.) When you break Apple's hardware-OS-Dev trinity you have to start fighting the API and the hardware instead of letting it work for you.
I don't think what you're doing will work and even if it does it will cost a lot of time and in the end time is money. Unless your being forced by external circumstances beyond your control to use this configuration, I would strongly suggest you do whatever it takes to find another way to accomplish what you want.
You won't get binary compatibility. Mac OS X uses the Mach-O object format and FreeBSD uses ELF, like linux. Cocoa won't work on platforms other than Mac OS, but if you stick to POSIX and open-source libraries though, you shouldn't have too much trouble building your CGI (and any dependencies) on your FreeBSD machine.
Also, Cocoa for a website? It's the Mac OS standard library for GUIs, associated datastructures, and various helpers. Apple used to promote something called WebObjects which was similar to Cocoa for the web, but I haven't heard anything about it in ages. I don't think Cocoa will work for a website, unless you just mean write a custom web server that has a graphical front-end in Cocoa.
I am currently in a class that is developing applications in Objective-C and Cocoa. I was wondering if there was any way to build and compile Objective-C applications on Windows Vista. During class, we are able to use the Mac machines provided to us, but I was hoping to do some work outside of class, and I only have a Windows Vista machine available to me. I have installed GNUStep. I am looking for a GUI or an IDE that I could use. I have Eclipse, and I tried to install ObjectivEClipse, but that is only for a Mac machine too. Any other suggestions? Thanks.
The compiler is no problem, since gcc includes an Objectve-C frontend. You could simply install Cygwin and use it. the issue is about libraries.
The Cocoa system is very Apple proprietary; but it's a descendant from NeXTStep. For a while (when NeXT was even deeper in debts than Apple) it was named OpenStep, and available as a shell around the NT kernel. Around that time, the GNUStep project was started, and it seems it's still there.
Note, however, that any xxStep libraries gives only a NeXT-like GUI, very different from modern macs. Also, a lot of the newer capabilities are not only new GUI; but new APIs too and these won't be found there.
in short... it's easier to go with a mac.
GNUstep itself offers ProjectCenter, which is a take-off of Project Builder, the NeXTstep IDE that Xcode is derived from. It also maintains the Interface Builder knockoff GORM.
Also, you'll want to bear in mind that GNUstep is a bit limited compared to Cocoa (just because Apple has a whole paid professional development team working on Cocoa full-time and GNUstep does not) and GORM uses a different format from Interface Builder, so if you're taking a class, there may be some Cocoa assignments you won't be able to do with it.
Under the heading of desperation measures:
It's old school but if you have a friend with a mac, you could telnet into the mac and run the dev tools there. You would code in an editor on Vista and then up load to the mac to compile.
That would only let you see the results of command line apps but it would better than nothing.
If the macs in your school lab are accessible you could just screen share from your Vista box. That's another long shot.
Might be easier to beg, borrow or steal a Mac mini.
The Cocoa frameworks are only available on Mac. For anything else, you'll have to use GNUStep.
I'm starting to learn Objective-C and I don't have a Mac (and I don't have plans to get one), but as I see that Cocoa is a very good framework to develop in Objective-C, I want to know: Is it possible to develop using Cocoa in Windows and Linux?
Thanks.
I think that your best bet, if you want to use Cocoa, is to get a Mac. You really won't regret it. GNUstep is a neat solution, but it is impractical to distribute applications built using GNUstep, because (as far as I know), clients must have the runtime installed for it to work.
Cocotron is an amazing project as well, and in the future, it may be useful for you if you want simple apps to run on both Mac OS and Windows. But you would still need a Mac to use it.
If you are interested in using a language like Objective-C with a framework like Cocoa, but don't want to get a Mac, why don't you try web application development with Cappuccino and Objective-J?. Objective-J is an implementation of an Objcective-C-like language in JavaScript, and Cappuccino is a really amazing imitation of the Cocoa framework in Objective-J.
Some examples of what can be created using that framework are 280 Slides and the new, stunningly beautiful EnStore. That's not a perfect solution, and unless you are content to just do web applications, you should buy a Mac.
Take a look at Cocotron
The purpose of the project is to provide an easy to use cross-platform solution for Objective-C development. In particular, source code level compatibility with recent versions of Apple's frameworks (OS X 10.4 and 10.5).
The general goal is to provide complete support on any viable platform, the project is intended to be as portable as possible. However, most of the work at this time is focused on providing support for Microsoft Windows. In particular the NT based versions, 2000 up to Vista.
You can also run Snow leopard Server inside a virtual machine, like VMWare Fusion.
Apple changed it licence in 2008 to allow that, but only with server editions. I have personally used it with some success to deploy iphone applications (Although it was admitably a bit slow).
You will need decent hardware and preferably a dedicated hard-disk drive to be able to use it properly.
And considering the cost of vmware and osx server you might be better off buying a used mac.
I'm in the process of learning Objective-c but would like to run code snippets via some sort of emulator on Windows — preferably web based.
I want to understand Objective-C syntax and walk through common code examples, probably via some sort of console. I would probably leave any framework type learning for when I get onto my MacBook, at home.
I have done a quick Google with no success.
It depends what you mean. Objective-C can be compiled by GCC, so you can happily create Objective-C test apps on Windows. If you are talking about the frameworks though, which contain most of the power when developing on OSX then it's a no unfortunately. You can get libraries compatible with SOME parts from gnustep.org (and run them on Linux/BSD), but it's still not the full OSX "stack".
You can get OS X running in VMWare, but it's illegal, so you best bet is to pickup a cheap Mac that can run Tiger/Leopard and use that.
Looked at GNUStep?
Another possibility is to use Cappuccino.
http://cappuccino.org
It is a cocoa-like framework for javascript, and looks very similar to objective-c.
The language is called objective-j.
AFAIK you can use the GNU compiler to compile Objective-C, so that should be usable on Windows too. This should be sufficient to get you started with programming the language.
For Mac OS X however the language is only part of the equation, you will want to program against the libraries of Mac OS X, and for that you will really need a machine running it.
I'm not sure which libraries are present and which are not but you can run OS X Server in a VM (providing you have an OS X Server license of course). This would allow you to have a virtual Mac environment on your Windows system.
As has been mentioned above, there's no way to achieve what you want natively within Windows as the underlying system is obviously different.
Good luck.
There also is The Cocotron.
