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
