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.

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.
