Project Description

Overview

This OS aims to provide a minimalistic and simple operating system that covers the basic functionalities expected from an OS.

Built-in Libraries

To maintain control and ensure that the system operates almost entirely from scratch, standard libraries are being rewritten. This approach helps in understanding the inner workings of these libraries and how they interact with the OS.

Completed Libraries

• string.h: String manipulation utilities.

Partially Made Libraries

• stdio.h: Basic input/output functions.
• stdlib.h: Standard utility functions.
• time.h: Time management functions.

Installation

Prerequisites

Building a Cross-Compiler

ByteOS uses an i686-elf-gcc cross-compiler. The versions used to build the project are:

• binutils-2.40
• gcc-12.2.0

For detailed instructions on building and using a cross-compiler, refer to the OSdev Wiki.

Note: Ensure you configure your cross-binutils with the --with-sysroot option.

Required Tools

Make sure you have the following tools installed:

• i686-elf toolchain.
• qemu-system-i386 for virtual machine.
• GCC (GNU Compiler Collection).
• LD (GNU Linker).

Build Instructions

1. Clone the repository:

   git clone https://github.com/iyksh/ByteOS && cd ByteOS

2. Build and run the project:

   ./run.sh       # This will automatically clean, build and run the project with QEMU
