We all know that Free Pascal can compile for the platforms that support Symbian OS, so is it possible to, painfully I must say, get a method to compile to the .sis format?
Many thanks!!
The port of Free Pascal to Symbian OS is not pretty ready yet. Though it is capable of writing helloworld applications, stdlib is not fully available yet.

I need to develop a software which works for both windows and Mac OS.
The requirement are follows:
User can view flash file, make the selection and software print out the user selected flash file list.
I have experience in .net and windows platform but no experience in Mac OS. What is best development language and tool for my current situation.
I may be a bit biased on this, but you should use Qt because it will make your code portable on Windows, Mac OS X, Linux and even some mobile platforms. I don't really understand your requirement but Qt is pretty much the all-round cross-platform solution. It's C++ based, but easy as such (no memory management hassle, Qt takes care of it all).
On one hand you could use Java, it's fully compatible with Windows, Mac and Linux, also the language is similar to C# so you could adapt without too much trouble, if you used .net with C#.
On the other hand you could use your knowledge in .net and use Mono. It's an open source library for running .net code in other platforms, It's not equal to .net (doesn't include all the libraries) but could solve your problem.
Hope my answer helps you.
Xojo is pretty easy to use and lets you make native Windows and Mac apps from a single source project so you might want to take a look at it.
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'm learning Objective-C and my friend have a real Macintosh IIci, that uses a Mac System 7(specifically 7.5.5 with a 68k processor) and I've installed Metrowerks C/C++ IDE(I think it's the version 1, but I don't know), but i didn't tested it, then i want to know one thing: It's possible to develop in Objective-C using NSObjects/Objects and AppKit or something like this on it? Thanks.
The short answer, as Stephen says, is no. But, just for fun, I started thinking about what you'd have to do to actually make that work.
1) You'd have to make gcc run on the 68k (gcc is the compiler that speaks Objective-C; you could probably substitute llvm for gcc, but let's not get too crazy). This is no mean feat. A quick look at the latest gcc builds does not show anything for that platform (unsurprisingly). I'm not an expert on gcc, but I bet it uses gcc-specific extensions and modern C so getting it to compile with an existing 68k compiler will probably be a non-starter.
So the first step for this will be adding an 68k back-end to gcc. This will allow gcc to spit out code that will run on a 68k. You could then use an x86 build of gcc with 68k support to cross-compile a new gcc binary that will actually run on your ancient Mac.
Having never messed with gcc before, I suspect that this task would take me about two-three years. Maybe more. but still, it's not impossible.
2) Once you've got a modern version of gcc that you can run on your 68k machine, you can use it to cross-compile for x86 or PPC. (Since you're talking about AppKit, you will never be able to actually RUN any of these programs on your old computer. All testing will have to take place on a more modern machine.) You now have to get all of the libraries and headers for Cocoa/Foundation/AppKit/libc/etc from your target machine (a PPC or x86 Mac) and put them somewhere that the gcc on your 68k can find. This will probably take a good 6 months of finagling to get right. But again, it shouldn't be impossible.
It might not be legal, though. As far as I know, the license agreements for OS X (which contains Cocoa) and Xcode will not let you move those binaries around willy-nilly to any machine you want. You would want to speak to a competent attorney before doing this as no one wants to get a visit from Interpol.
3) I think you're done at this point. You can write Objective-C/Cocoa code on your Mac IIci, compile it for a PPC or x86 Mac, ship it off to an OS X box using your favorite method (I've only been a Mac guy since 2005 so I don't even know the connectivity options on the IIci), and test and debug it rather painfully.
At this point, you have access to a Mac running OS X on either a PPC or x86 chip. And you will wonder why you don't just do all your development on THIS machine instead. And since you've spent a few years getting your IIci development environment set up, buying an old PPC Mac for development will be cheap.
Still, it could be a fun idea. It'd probably get you on the reddit front page if you pulled it over. (Though, honestly, it'd be easier to just fake it for YouTube if that's all you're after.)
Short answer: no.
Objective-C became the lingua franca of mac development with OS X, which went into beta 10 years or so after that computer shipped. Most development for pre- OS X systems was done with C or C++.
Without OS X, you won't have any of the system libraries or headers to link against, and the Metrowerks compiler won't know anything about the Objective-C syntax or runtime extensions to C.
To top it off, the Objective-C frameworks are built for PowerPC (or now, Intel) macs, whereas the processor in that machine uses the older 68k architecture.
gcc was still being compiled for 68k Amiga in the early noughties, so there might be some chance to get it working on 68k Mac OS. I believe Objective C extension were available from at least the early 90s for gcc.
Another option is to use 68k Linux. There is an port of Debian 4.0 (etch) for 68k, and a current effort to revive it, so you could likely get a fairly recent version of gcc running.
There is also the possibility to cross compile.
The contemporaneous C environments (no idea if any had supporting Objective C) were Think C (later Symantec C++) and Apple's Macintosh Programmers Workshop. In theory, you might get one of these to compile an objective C supporting version of gcc.
No, it's not possible they are just too old to my knowledge.
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.
Is there an IDE that I can load on a Blackberry, E71, or an iPhone?
Apple released iPhone SDK for XCode a while back, check out developer.apple.com and Nokia also release their own SDK check out forum.nokia.com
But for pure Java Midlet goodness, i would recommend Netbeans (netbeans.org) their netbeans mobile application editor is a gem, second to none.
To answer your question, i don't think any phone is powerful enough to compile and test the code on themselves, so no ...
Not that I know of, typically you'll develop apps on a desktop machine (PC/MAC whatever) and download/control the application on the phone. Also I don't think Java is available on a standard (non-cracked) iPhone.
There was a palm based C compiler. I had some trouble finding it though, but it's called OnBoard-C. It didn't exactly have an IDE, it compiled notes. Considering there's a lack of embedded compilers, I'd be surprised to find full embedded IDEs. Oh... I recall there being a Scheme or Lisp too.
This maybe premature but, congrats, you just found a market niche.
