Rust Compiling for the Kindle

How to compile a rust binary that can run on the kindle natively

Background

I wanted to create a weather dashboard for my kindle. There were some existing solutions, but they tend to be super simple or extremely limited.

Instead I wanted something that was:

  1. Stable so I could set and forget
  2. Information heavy with all my favorite stats
  3. Customizable for future use

Naturally, wanting to explore a new language, I chose Rust to acheive these goals. However, I could not find any information on how to compile for it!

Solution

After some tinkering and exploring existing binaries, I found which target the kindle would support and combined it with static linking:

1

RUSTFLAGS="-C target-feature=+crt-static" cross build --target arm-unknown-linux-musleabi --release

I used cross to avoid having to deal with a lot of additional pain.

Final notes

You can find my finished project, here.

I think it’ll be interesting to see if there is a way to create a KUAL extension with this rust compiling in mind. Maybe that is a project for another day.
