My work in progress. First step is getting the keyboard controller fully operational, then I can start working on parsing user input into something interesting.

This repository contains the code from the "Building an OS" series on the "Nanobyte" YouTube channel.

First, install the following dependencies:

# Ubuntu, Debian:
sudo apt install build-essential bison flex libgmp3-dev libmpc-dev libmpfr-dev texinfo wget \
                   nasm mtools python3 python3-pip python3-parted scons dosfstools libguestfs-tools qemu-system-x86

# Fedora:
sudo dnf install gcc gcc-c++ make bison flex gmp-devel libmpc-devel mpfr-devel texinfo wget \
                   nasm mtools python3 python3-pip python3-pyparted python3-scons dosfstools guestfs-tools qemu-system-x86

# Arch & Arch-based:
paru -S gcc make bison flex libgmp-static libmpc mpfr texinfo nasm mtools qemu-system-x86 python3 scons

NOTE: to install all the required packages on Arch, you need an AUR helper.

I had to run this to get guestmount to work without sudo:

sudo dpkg-statoverride --update --add root root 0644 /boot/vmlinuz-`uname -r`

Then you must run python3 -m pip install -r requirements.txt

After that, run scons toolchain, this should download and build the required tools (binutils and GCC). If you encounter errors during this step, you might have to modify build_scripts/config.mk and try a different version of binutils and gcc. Using the same version as the one bundled with your distribution is your best bet.

Finally, you should be able to run scons. Use scons run to test your OS using qemu.
