## Setup

You need a few things to build this:

* Rust nightly

* `cargo-xbuild`

* `nasm`

* A cross binutils targeting x86_64-elf

### MacOS

1. Install Rust with [rustup](https://rustup.rs/). Make sure install nightly and select it as your default compiler.

1. Install `nasm` from Homebrew:

    ```

    brew install nasm

    ```

1. Install `cargo-xbuild` from cargo:

    ```

    cargo install cargo-xbuild

    ```

1. Install binutils from source. I build my cross compilers into `~/cross`, but anywhere works.

    ```

    curl -O https://ftp.gnu.org/gnu/binutils/binutils-2.32.tar.gz

    tar xf binutils-2.32

    cd binutils-2.32

    ./configure --target=x86_64-elf --disable-werror --prefix=$HOME/cross

    make && make install

    ```

## Building

```

make

```

## Known Bugs

* QEMU's TCG accelerator (the default) has a buggy implementation of the FS.base and GS.base MSRs. Use the KVM or HVF accelerators instead.
