Can someone tell me how to build my own OS....like those in iron man movies...which language is used for such OS.I want to learn those languages give me a preferable link or a book name for learningit.

Can it be created using c++ ..,,if yes then how...?????

I think that you are in for a huge disappointment....

To get started it might be useful to have a look at a fairly simple OS, like: FreeDos[^]

Are you talking about creating/making a new Operating System, or simply a "nice" Graphical Interface (GUI) that will live on top of an existing Operating System ?

Graphics: Have a look at DirectX (or whatever it is called now) and OpenGL;
Voice recognition: MS Speech Recognition[^]

One is very difficult (the OS); the other one simply difficult.

Here at CodeProject we have even this: article series by 0x3c0[^].

In fact it is not that daunting a task. Really, an operating system is the code that takes over from the boot loader. As others here have hinted at, you won't get much success on conventional machines that you buy in a computer store. On the other hand, that is pretty much what you do with embedded systems. Look at Arduino or Raspberry Pi and research ARM architectures. Google is your friend and will help you with this.

Here is a link[^] where some students wrote an operating system for a Raspberry Pi that is a 2 player chess game. They wrote an ARM7 assembler in C, then wrote the chess program/operating system in ARM7 assembly. The code is 15000 lines and they did it in 2 weeks.

Absolutely nailed it. My +5

Exactly.

Look at CP/M or DOS. Both are valid examples of operating systems, and they are teensy tiny compared to today's mainstream OS's.

Zoltán Zörgő 1-Jul-13 17:03pm

True. Still, I don't think that even a DOS level OS is a task for OP.

I like your answer, Harvey. Writing a tiny operating system, or at least the core parts of it, can be done by a single programmer. But it takes quite some insight into the architecture of a processor and into programming concepts to do it. This is definitely no good start for a beginner - and in that regard I can subscribe to what Zoltán said. Hence my 5 to both of you.

It depends what you want to do with it. I wrote my own OS for a PDP-11/05 which had 8K memory. It accepted keyboard input, had printer/console output, did some mathematical computations and flashed different console lights when events triggered. I learned a lot from it and it was not complicated. I was not a beginner at the time but did not use too much in the way of advanced concepts. All unassisted.

It depends on what you want to do. Also look at the Arduino platform. I would claim that nobody in that genre are expert programmers (ummm okay, maybe 3 or 4 of them).

Most of us are used to highly complex OSs with many features, but the basic functionality is not that hard. I re-read OP's question and I think he/she could have some reasonable success.

P.S. don't hack off somebody who wants to be in an Iron Man movie. :-)

Makes sense, a 5.

Solution 1

Sorry, but if you ask such questions you are far-far away from being prepared for such a task. Making an operating system is really-really-really complicated. Just download any operating system source code, and see for yourself:
Android: https://source.android.com/source/[^]
FreeBSD: http://www.freebsd.org/developers/cvs.html[^]
ReactOS: http://www.reactos.org/download[^]
...and so on...
