ABOUT GHOST

Ghost is a hobbyist operating system for the Intel x86 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.

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

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.
