Ghost is a hobby operating system for the Intel x86 platform. The project is licensed as GPLv3. It was started as a research project to learn more about low-level software programming and computer internals. The sources are available on GitHub.
The kernel and the userspace applications are written from scratch in C++ and Assembly (and some C). It is not based on any existing kernel. There is a POSIX.1 compatibility layer to simplify porting some software to the system.
- Symmetric multi-processing
- Patched GCC (OS specific toolchain)
- IPC (pipes, signals, messages, shared memory)
- ELF executable & shared library support
- libc, self-made
- libghostapi, kernel API library
- libghostuser, simplified file I/O, creating UIs etc.
- libstdc++ port
- VESA video driver
- Window server (GUI with homemade toolkit)
- PS/2 keyboard & mouse driver
- Userspace filesystem driver support
- Serial COM1 debug interface
- Virtual 8086 for BIOS calls
- Copy-on-write implementation, fork()
My name is Max and I'm a software developer from Bavaria, Germany. I started Ghost in 2014 because I wanted to gain knowledge about how operating systems work and what happens under the hood, and well - it's just fun to build something from scratch. The biggest sources of knowledge are the OSDev Forums and wiki and the LowLevel sites.
