# Limine Bare Bones
|
|
|
|
This repository will demonstrate how to set up a basic higher half x86-64 kernel using Limine.
|
|
|
|
It is recommended to cross reference the contents of this repository with [the Limine Bare Bones](https://wiki.osdev.org/Limine_Bare_Bones) OSDev wiki page.

## How to use this?
|
|
|
|
### Dependencies
|
|
|
|
All `make all*` targets depend on a GNU-compatible C toolchain capable of generating x86-64 ELF objects. Usually `gcc/binutils` or `clang/llvm/lld` provided by any x86-64 UNIX like (including Linux) distribution will suffice.
|
|
|
|
Additionally, building an ISO with `make all` requires `xorriso`, and building a HDD/USB image with `make all-hdd` requires `sgdisk` (usually from `gdisk` or `gptfdisk` packages) and `mtools`.
|
|
|
|
### Makefile targets
|
|
|
|
Running `make all` will compile the kernel (from the `kernel/` directory) and then generate a bootable ISO image.
|
|
|
|
Running `make all-hdd` will compile the kernel and then generate a raw image suitable to be flashed onto a USB stick or hard drive/SSD.
|
|
|
|
Running `make run` will build the kernel and a bootable ISO (equivalent to make all) and then run it using `qemu` (if installed).
|
|
|
|
Running `make run-hdd` will build the kernel and a raw HDD image (equivalent to make all-hdd) and then run it using `qemu` (if installed).
|
|
|
|
The `run-uefi` and `run-hdd-uefi` targets are equivalent to their non `-uefi` counterparts except that they boot `qemu` using a UEFI-compatible firmware.
