Hey Everyone,

So later next month I will be starting the process of making a kernel for one of my classes. Anyways, I haven't done C in a long time and figure I'd do some brushing up.

You guys have any book recommendations? Or site recommendations that might be more specific to what I would be doing with?

Thanks a bunch


EDIT:

no kernel... YAY! Just a mini-shell. still

EDIT #2:

The quarter has officially started and I figured I would post my progress for this class throughout the quarter.

Since I am both new to C as well as most of the Unix environment I figured this might be a good place to get feedback on my code.

It's really just one program but 6 revisions.

Program 1 -- http://www.overclock.net/7291306-post13.html
Program 2 -- http://www.overclock.net/7373582-post14.html
Program 3 --
Program 4 --
Program 5 --
Program 6 --

The language itself or OS-level programming? If you want a C book, K&R is the Bible

Great, thanks for the link.

I am kind of looking at both things. I've never coded in C let alone in a linux environment and nothing remotely complex as a kernel.

Thanks again, +rep.

if you're looking for some more info on operating systems (as well as setting up cygwin, building a cross compiler, etc...) osdev seems to have a fair amount.

Hold up - you've never coded in C before, and you're tasked with making a kernel?? Good luck with that!!

Or are you just tweaking the existing Linux kernel from the source code?

nope, it's a kernal from scratch.

I've done C++ and C# but never C.

lol. This is one class I am not really looking forward to. It shouldnt be too hard I don't think, there's just going to be a nice learning curve.

Thanks for the responses btw

Please let us know how it goes. Zero-C to Kernel in X days.... ouch.

sounds like a steep learnign curve my friend, K&R will help for sure, and man pages lol

That simply isnt possible. You dont have the C skill nor the knowledge of Linux to write/modify a kernel. You also would need a deep understanding of how computers really work.

If you have some time to go at it yourself, or need a project. Write a 512b OS. Write your kernel loader (16bit real ASM), kernel (asm/C), enter protected mode (CR register fun), and write a keyboard input driver. That would help you learn a lot more, but youre still years away from doing so.

I hope your teacher intends on holding your hand through this one, best of luck.
