I'm new here so please bare with me if this is the wrong forum (sorry if it is). I put it here because I believe you can contruct a kernel in c right? I've downloaded the linux kernel and thats full of c source files.

Anyway, i've been using windows and linux for so long and was wondering can I build my own kernal? I'm out of a project at the moment and wanted something to do. I don't want to recompile the linux kernel as so many other threads talk about. I would like to build one from scratch. I'm not expecting anything like linux but something small that I can handle and just do as a hobby that has a few basic features such as writing a text file saving it to the hard disk and then reopening it.

Could anyone give me any pointers as to where to start? Any good tutorials? I mean Linus Torvalds had to start somewhere.:)

Regards,

James

You know it took Linus Torvalds years to make the very first 'very simple' Linux kernel.

If your interested in this area ckeck out Minix.

Thanks,

I know it takes ages but im not bothered I'll only do it as a hobby, nothing serious.

Also if I was to build it from scratch how would I compile it? GCC? Because that would compile to a linux executable. Wouldent it?

How easy would it be to say.... hit the b key and it makes the computer shut down for instance?

Actually a good place to start is investigating the options available with GCC(GNU compiler) and ld(GNU linker). With these two utilities you can build just about anything you want...

You'll probably have to learn first about general kernel concepts and theory before any implementation. Why not start by making some google searchs?
(I just tried and found: http://en.wikipedia.org/wiki/Kernel_(computing).)
I guess writing a kernel from scratch implies really understanding what's going on in a computer...
