COS - A hobby OS project

COS is a hobby OS development project which I sporadically work on to further my programming skills in C and C++ and my understanding of computer systems. I intend to stick to these two languages for the whole project.

Documentation is sparse, but you can use doxygen to build it from the in-code comments.

DISCLAIMER: COS is not Windows or Linux or what-have-it, I cannot vouch for its stability! Though I make my best effort to ensure it works as expected, running this on your potato may end up cooking it! Please don't run this on any even remotely important hardware. VMs are okay :)

Capabilities

• It boots up on most modern-day 64-bit systems that support x86_64 (so no ARM)
• It can print stuff on your screen
• It can do some basic memory management with paging
• More to come

Setup

Prerequisites

In order from critical to meh:

• [required] x86_64-elf targeting cross compiler (I wonder how you could set that up)
• [required] git so we can download limine (sudo apt install git or similar)
• [required] xorriso to build ISOs (sudo apt install xorriso or similar)
• [optional] doxygen for documentation (sudo apt install doxygen or similar)
• [optional] qemu-system-x86 if you want to use qemu.sh to run COS (sudo apt install qemu-system-x86 or similar)

Actually building (and running) COS

You can run the following code to download and build COS:

git clone https://github.com/ryuukumar/cos.git && cd cos
chmod +x build.sh
./build.sh

This will generate a file image.iso inside your working directory. Use VMWare or your favourite VM emulator (or put it on a liveCD if you're brave enough) to run and test it out. Or run qemu.sh to run it on QEMU.
