This repository will demonstrate how to set up a basic kernel in C++ using Limine.
Anymake command depends on GNU make (gmake) and is expected to be run using it. This usually means usingmake on most GNU/Linux distros, orgmake on other non-GNU systems.
It is recommended to build this project using a standard UNIX-like system, using a Clang/LLVM toolchain capable of cross compilation.
Additionally, building an ISO withmake all requiresxorriso, and building a HDD/USB image withmake all-hdd requiressgdisk (usually fromgdisk orgptfdisk packages) andmtools.
TheARCH make variable determines the target architecture to build the kernel and image for.
The defaultARCH isx86_64. Other options include:aarch64,loongarch64, andriscv64.
Runningmake all will compile the kernel (from thekernel/ directory) and then generate a bootable ISO image.
Runningmake all-hdd will compile the kernel and then generate a raw image suitable to be flashed onto a USB stick or hard drive/SSD.
Runningmake run will build the kernel and a bootable ISO (equivalent to make all) and then run it usingqemu (if installed).
Runningmake run-hdd will build the kernel and a raw HDD image (equivalent to make all-hdd) and then run it usingqemu (if installed).
For x86_64, therun-bios andrun-hdd-bios targets are equivalent to their non-bios counterparts except that they bootqemu using the default SeaBIOS firmware instead of OVMF.
