Ghost OS

Ghost is an x86-64 operating system written in C, C++ and assembly, with a microkernel, userspace drivers and the ƒenster desktop.

This project is independently developed and not based on Linux, BSD, or any other existing OS.

Build and run

The build guide covers the cross-toolchain and component targets. For the Docker environment, run from the repository root:

git submodule update --init
./docker-build-toolchain-image.sh

Inside the container, ./build.sh --ci produces target/ghost.iso. Boot it with an x86-64 VM, for example:

qemu-system-x86_64 -cdrom target/ghost.iso -m 1024 -smp 2

The installer copies the live system to an empty AHCI disk for persistent FAT-backed boot.

SMP kernel with ELF/shared-library loading, tasks, IPC and memory management.
libapi syscall wrappers, a C runtime and an x86_64-ghost GCC toolchain.
PCI, ACPI, PS/2, AHCI, FAT, boot-framebuffer and VMSVGA services.
ƒenster window server/UI toolkit, desktop, terminal, shell, editor and file browser.
Ported Cairo, FreeType, Pixman, libpng, zlib and musl mathematical routines.
