Cross compilation

This example is for running on a Raspberry Pi Zero 2 W (ARMv7). For a Raspberry Pi Zero (ARMv6) replace armv7-unknown-linux-gnueabihf with arm-unknown-linux-gnueabihf

Cargo

• Add target with rustup :

rustup target install armv7-unknown-linux-gnueabihf

Note: you may need to install cross-compiler stuff like the gcc-arm-linux-gnueabihf package on Debian.

• Build with cargo :

cargo build --release --target armv7-unknown-linux-gnueabihf

With Cross (https://github.com/cross-rs/cross)

• Installation:

cargo install cross --git https://github.com/cross-rs/cross

• build with cross :

cross build --release --target armv7-unknown-linux-gnueabihf
