ABOUT GHOST

Ghost is an operating system for the Intel x86 platform. The project is licensed as GPLv3. The kernel and the userspace applications are written from scratch in C++ and Assembly (and some C). The kernel is not based on any existing kernel and partially Unix-compatible.

This is the main development repository.

Project website: http://ghostkernel.org/

Status of redux

With redux I started a re-implementation of the kernel which is now present in the master branch. Currently I'm working on rewriting most of the filesystem related calls. Once a ready-to-run version is there, I will post a live CD on the website.

If you are looking for the previous kernel implementation (versions up to 0.5.6b), check the legacy branch out.

Documentation

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