Building And Running

Make sure you have following programs installed:

  • Clang
  • lld
  • llvm
  • Make
  • Nasm
  • Qemu x86-64
  • Xorriso
  • Wget
  • Tar

If you have Debian based system (Ubuntu, linux mint, Pop_os! etc) you can install them with this command:
sudo apt install clang lld make nasm qemu-system-x86 xorriso wget tar

Follow these steps to build and run the os

  1. Clone this repo with:
    git clone --single-branch --branch=master --depth=1 https://github.com/ilobilo/kernel

  2. Go to the root directory of cloned repo and run:
    make -j$(nproc --all) For UEFI mode
    make bios -j$(nproc --all) For BIOS mode

If you, for some reason, are on Termux, run this command instead and connect to 127.0.0.1:5901 with VNC viewer:
make vnc -j$(nproc --all)

Options

  • USEILAR=1: Use ILAR archive format for initrd instead of USTAR (requires libboost-iostreams-dev)
  • NOUBSAN=1: Turn off UBSAN
  • NOCLEAN=1: Don't clean the source after compiling
  • NORUN=1: Don't run the kernel, just compile
  • DEBUG=1: Turn off kvm and enable qemu logging
