A toy OS in Rust
This is based on Philipp Oppermann's excellent series of blog posts. It's purely a learning exercise, to see what Rust feels like on bare metal.
First, we need to check out the source and rebuild the Rust runtime using a bare-metal target and no hardware floating point support:
# Get our source code. git clone https://github.com/emk/toyos-rs.git cd toyos-rs # Set up a Rust compiler. curl https://sh.rustup.rs -sSf | sh rustup update nightly-2016-09-16 rustup override set nightly-2016-09-16 # Get a copy of the Rust source code so we can rebuild core # for a bare-metal target. git submodule update --init make runtime
From here, we should be able to build a kernel and run it using QEMU:
You should be able to type.
