# ABOUT GHOST

**Ghost** is a hobbyist operating system for the x86-64 platform.

The OS is written from scratch in C/C++ and Assembly.

This is the main development repository.

**Project website:** http://ghostkernel.org/

## Documentation

See the `documentation` folder. It contains information about the technical design as well as detailed building instructions.

A usually up-to-date version of the documentation is provided here: https://ghostkernel.org/documentation/

## Live ISO

If you just want to play around with the latest state, you can download an ISO

image from the [release section](https://github.com/maxdev1/ghost/releases).

The suggested way to test it is in VirtualBox with at least 512MB of RAM and the

VMSVGA graphics adapter enabled for better performance.

## Quick-start

1. On your host machine (where Docker is installed), run `./docker-build-toolchain-image.sh`. This will 

    build an image that contains the cross-compiler and other tools required for building the operating system.

2. Once the process has finished, it will open a bash within the container. The container has this repository folder mounted to `/ghost/source`.

3. Build the operating system by running `./build.sh` in that directory within the container.

Afterwards, the `target` folder will contain the bootable ISO image.

## Features

* x86_64-based micro-kernel

* SMP multi-processor support

* Comprehensive kernel interaction library (libapi)

* Own C standard library (libc)

* OS-specific GCC toolchain

* ELF binary & shared library support

* Window server & toolkit

* Support for C++ in kernel & userland

* Various interprocess-communication methods

* Drivers for

  * VESA/VBE video output

  * PS/2 keyboard & mouse

  * PCI handling

* Limine protocol compliance

* It's also very cool

The OS uses the [fenster windowserver](https://github.com/maxdev1/fenster) which originated from this project:
