WAIT! Have you read Getting Started, Beginner Mistakes, and some of the related OS theory?

Notes

• The rust libcore can easily be included in a kernel, it's analogous to C's freestanding headers
• Enable `--gc-sections` in ld to avoid having to define symbols you don't need (e.g. floating point math functions)
• Always use a target json file (Flexible Target Specifications)
• If you're building a UEFI app, disable function sections as well
  • rustc puts every item in its own section by default. The PE format has a limit of 96 sections. So unless you disable function sections, your project will most likely fail to load.

Examples

• https://github.com/thepowersgang/rust-barebones-kernel - A framework written in rust 1.0 alpha, supporting x86 and x86-64, boots off multiboot.
• https://github.com/charliesome/rustboot - VERY old (rust 0.7), includes a bootsector.
