Building my own OS

Question

I want to build my own OS and I want to know what programming language should I learn?
I already know Java.But i saw that will not help.Should I learn C or C++ for building OS??

Answer 1

Design a OS in now days from scratch might still be a hard work but not imposible if you have the will and a great team of developers with you.

You will need at least Assembly, but that would be painful for you because you will have to handle and consider the diferences among a lot of procesors that your OS will have to support, because the Assemby language differs from one to another .

So you will need something that can help you a bit with that problem and you can focus on what is more important without redesigning your system for each processor, for your epic quest you will need a general purpose language like C/C++, Java, C# , etc.

I would recomend you to use C or C++, they are fast, reliable, and support Assemby code inline with your C/C++[1] code, giving you a great control over hardware and performance without going crazy writing everything on Assembly.

Answer 2

Before learning any language, you should learn basically what are the different component of an OS ^^
If you always plan to build one by your own, meaning from scratch/zero, you need a lot of practice before starting your project, and of technical knowlendge...

Well so, my advice to you, is rather to build it totally from nothing, learn to build it ( ie: from a gnu/linux/debian base -- you just need to learn command line terminal :P ) at least at first, to have a good view of the work intended to make an OS ;)

Answer 3

@Theo:

... and so, what's:

++
C++

?:P

Whitout joking, C is still a relevant proven language that continue to be widely useful, especially on low level programming, for which oriented object concept aren't adapted... and it's widely too anchored in the adn of a lot of languages which have succeeded.

Answer 4

You probably can do it in a virtual instalation of a linux, but you probably too add problems sources, and at least lower performances in compiling...
Looking at documentations/tutorial, even without do it, will certainly learn a lot to you ;)

Answer 5

I have not tried this myself, but this may help. (other may comment)

Answer 6

#visph -- yeah! The problem is that I do not use Linux,I am windows user... Can I do that with VirtualBox??

And also, I am ready to learn anything I just started c++ course here and after that I will learn Assembly

Answer 7

I asked it to a friend yesterday.
So, he said:
"You should not start a house by the roof, but once you're in it for real, and you'll know when it is, you'll want to play a little with Minix first."

Answer 8

Ekansh, I thought C was replaced by C+ and then C++. You're saying that C is still a relevant language?

Answer 9

I saw a Web page that says that I should learn C to build OS and C ++ for games is that right? I mean should I learn C now instead C++¿¿?
