# Linux-from-scratch
*These binaries/kernel were compiled with CLang(LLVM)!*
Binaries ready to run Linux on arch's: Arm64, x86_64 & RiscV64 with QEMU.
# Description
- Kernel: 6.11.0 with LLVM(clang version 17.0.6) and Rust Support Enabled.
- Bash: BusyBox 1.36.
- BootFS: initramfs.cpio.gz
- Init Script: /init
# TODOs
- Add C Compiler (like a TinyCC)
# Required
QEMU
We will use Qemu for launching Linux on our X86_64 hardware.
This is ideal for prototyping in a RISC-V without having specific hardware.
QEMU is a generic and open source machine emulator and virtualizer.
RHEL Linux
```
sudo dnf install qemu-system-riscv qemu-system-x86_64 qemu-system-aarch64
```
# How to run:
```
./start.sh
```
