ToAruOS: A Hobby Kernel & User-Space, Runs Mesa & GCC

ToAruOS is a hobby kernel and user-space that can form a working operating system with some common open-source third party libraries. ToAruOS has been in development for nearly four years and was born at the University of Illinois at Urbana-Champaign.

ToAruOS is an open-source operating system mostly written from scratch for its key components. The ToAruOS kernel supports many Unix-like features including process/thread support, ELF binary support, pipes and TTYs, virtual file-system support, EXT2 file-system support, etc. The user-space to the operating system features a custom built Cairo-powered composited window manager, a terminal emulator, and other demo applications.

Third-party software support by ToAruOS includes GCC, binutils, libpng, FreeType, Cairo, Pixman, Mesa with using its software rasterizer, and Vim. There's also ports in process for Lua, SDL2, Bochs, and Python, among other applications.
