Ghost is an operating system for the Intel x86 platform written from scratch in C++ and assembly. It aspires to follow a pure micro kernel design and do stuff as clean as possible. Some of the important features are:

• multiprocessor & multithreading support
• window server, GUI with homemade toolkit
• patched GCC, OS specific toolchain
• custom libc implementation
• libstdc++ port
• extensive kernel API library (libapi)
• userspace C++ library (libuser)
• PS/2 keyboard & mouse driver, VESA video driver
• userspace filesystem driver support
• ELF binary support
• ipc mechanisms: pipes, signals, messages, shared memory
• named processes
• serial COM1 kernel logging
• virtual 8086 for BIOS calls

This is the bleeding edge source version of March 20, 2016. Version 0.5.2

This release contains a lot of changes, especially a big bunch of refactoring work. The filesystem and the thread setup code where cleaned up. Added a changelog that contains details.

• applications sources for the essential system applications
• documentation about kernel concepts and features
• kernel sources of the kernel
• libapi sources of the userspace API library
• libc sources of the Ghost C library implementation
• libuser sources of the C++ userspace library
• patches patches & instructions for ports and toolchain setup
• tools set of tools that are used for development

There is an additional repository, the ghost-sysroot that is used as the base for the filesystem image for a blank installation.

See the patches/toolchain/TOOLCHAIN.md for instructions on how to set up the toolchain.
