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

Building
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:

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

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

Next, modify the configuration in build_scripts/config.py . The most important is the toolchain='../.toolchains' option which sets
where the toolchain will be downloaded and built. The default option is in the directory above where the repo is cloned, in a .toolchains
directory, but you will get an error if this directory doesn't exist.

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 scripts/setup_toolchain.sh 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.
