KarlOS

KarlOS is a student effort in Karlsruhe to create a hobbyist Operating System from scratch. The current goal of the project is to develop a simple monolithic kernel for 64-bit Intel / AMD PCs, which could serve as a platform for experimentation in the future.

Build Dependencies

You will need:

  • A x86_64 cross-compiler GNU toolchain
  • GNU make (the current Makefile is unfortunately not compatible with BSD make)
  • mkbootimg (part of [^BOOTBOOT])
  • qemu-system-x86_64 to run the kernel in an emulator

Installing Dependencies, Building, and Running

See our wiki page.
