This repo contains the code from the "Building an OS" tutorial 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 \
nasm mtools qemu-system-x86
# Fedora:
$ sudo dnf install gcc gcc-c++ make bison flex gmp-devel libmpc-devel mpfr-devel texinfo \
nasm mtools qemu-system-x86
After that, run make 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 make. Use ./run.sh to test your OS using qemu.
