rustboot

A tiny 32 bit kernel written in Rust.

This is a fork that fixes rustboot to run on my macOS. It adds some comments for my own learning.

Setup

You need a few things to run rustboot:

1. qemu
2. a cross-compiler for i386
3. nasm
4. Rust >= 0.7 release.

macOS

To set things up on macOS, do this:

Install nasm and qemu from homebrew:

$ brew install nasm
$ brew install qemu

Make sure the brew version of nasm is being used:

$ nasm -v
NASM version 2.11.02 compiled on Apr 14 2014

Install binutils from source.

I personally keep things I manually compile limited to my home directory, so I use the --prefix=/Users/aunn option. Put this wherever you want, of course.

$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.24.tar.gz
$ tar xf binutils-2.24.tar.gz
$ cd binutils-2.24
$ ./configure --target=i686-unknown-linux-gnu --disable-werror --prefix=/Users/aunn
$ make && make install

Then, make sure that ~/bin is in your PATH, if you're using a prefix:

export PATH=$PATH:~/bin

Running it

To compile, simply

$ make

To run,

$ make run
