Requirements

Linux

In a debian-based linux environment, the following command should install everything: sudo apt install build-essential gcc gettext make perl libssl-dev ninja-build clang flex bison libgmp3-dev libmpc-dev libmpfr-dev texinfo python3-pip qemu-system-x86 help2man autopoint gperf nasm llvm mercurial groff && pip3 install xbstrap && pip3 install mako && pip3 install meson

Building the toolchain

Run make bootstrap and wait, it will build the hosted toolchain, ported software, and mlibc.

Building the OS

Typically you'll want to either run make clean run-linux or make clean debug-linux. You can optionally add ENABLE_KVM=1 at the end to have a faster emulation if your system supports KVM.
