beeos's Introduction

BeeOS

README

A simple and minimal "Unix-like" kernel trying to be POSIX compliant. (at least with respect to the implemented services).

The kernel is NOT STABLE for production and is a discontinuous work mainly used as a didactical tool for operating systems and low level programming.

Because of it's simplicity it can be used as a trampoline to start digging with common operating system problems.

Once you've mastered the BeeOS sources it will be a lot easier to start hacking with more complex OS projects.

Prerequisites

gcc
binutils
make
qemu (qemu-system)

Quickstart

make all

This command will build the kernel, standard library (libc), user utility library (libu) and user applications.
(cd misc && sudo ./mkfs.sh)

Creates the root filesystem ramdisk with the user applications.
(cd misc && ./qemu.sh)

Starts qemu and BeeOS.
