The goal is to create an object file (just a ".o" embedded inside of rust's .rlib) that can be linked into a larger C project with avr-gcc
Unfortunately, with the following command:
XARGO_RUST_SRC=/home/chris/other/avr/rust/src xargo build --target avr-unknown-unknown -p core
I get:
[chris@manaslu avr-rust-test (master ✗)]$ XARGO_RUST_SRC=/home/chris/other/avr/rust/src xargo build --target avr-unknown-unknown -p core
