Far From *NIX OS (FFSNIX OS)

An operating system based on the x86_64 architecture. Will hopefully emulate a UNIX OS in the future. Written in C++ for now. Rust planned for later.

Build instructions

1. Download required dependencies.

Debian/Ubuntu

sudo apt-get update
sudo apt install build-essential bison flex libgmp3-dev libmpc-dev libmpfr-dev texinfo nasm

Arch/Manjaro

sudo pacman -Sy
sudo pacman -S base-devel gcc nasm

2. Run script to build toolchain.

sh build_toolchain.sh

This can take anywhere from 10 minutes to a couple hours depending on how fast your system is. You can use an x86_64-elf prebuilt toolchain

3. Run script to build the kernel.

sh build.sh build

Running the OS

qemu-system-x86_64 src/out/os.bin

Cleaning build directory

This will delete all built files

sh build.sh clean
