Consider this: when you build a program for Windows, the binary that it spits out isn't going to run on Linux, and vice versa. There are "platform libraries" that do different things on different systems, and you need to pick one to use. When you do a normal install of Rust on your system, you get a version of Rust that runs on your system, and that also has all the files necessary to produce binaries for your system. By installing a different "toolchain", you're still using a version of Rust that runs on your system, but you're getting all the libraries (and potentially other tools) needed to produce binaries for some other systems. As far as Rust is concerned, if you've already done rustup target add arm-unknown-linux-gnueabihf then there's probably nothing more to do there. I would try using the official OS and cross-compiling like you successfully did before just to see if it works on the new machine. If so, then it sounds like the question is with Arch Linux.

April 1, 2023Has anyone programmed a Raspberry Pi with Rust?
(I'm assuming crosscompiling then running on Linux, not bare-metal (but that also should be possible)) Not a big project, but I've run simple HTTP server on one. To be honest, with Rust it mostly just:
rustup target add arm-unknown-linux-musleabihf cargo build --target arm-unknown-linux-musleabihf
You might need to adjust target, depending on which Raspberry Pi version you're using.
In my case, because I've fairly old one (RPi 1 B+), I had to additionally download gcc toolchain (for linking) from arm's website, as the one from distro didn't support armv6.

r/rust on Reddit: What steps are needed to cross-compile a program that runs on my raspberry pi zero 2 w?
July 6, 2024 -
Hi, I already succeeded partially in this as I compiled a rust program for my raspberry pi zero w (the first version). Let's call that one rp0w1 and the new version rp0w2 for clarity.
On my rp0w1 I run rasberry pi os, because that's the only OS supported. I oriented myself on this blog post: link
On the rp0w2 I am running arch linux (arm) though, because I prefer it. And the toolchain isn't correct (the one also mentioned in the blog post).
I would like to know what steps would be needed in order to get a binary that I can run on my rp0w2. I am also not entirely sure what toolchain means in this context. I already have a toolchain installed through rustup don't I? Why do I need additional files?
Can I simply download some files from ARM or what do I do?

Cross-compiling to Raspberry PI is easy, and works great. Compiling on a Raspberry PI is rather painful due to long compile times.

By setting different tags for your Docker image and RUST_VERSION you could easily build images for different version of rust and use them as need. Cross-compiling with your own build image works exactly as with the one pulled from the dockerhub.

September 9, 2024 - It acts as a drop in replacement for cargo build and cargo run, but it handles all the cross-compilation for you. You can specify the target architecture with the --target flag, but you can also specify a default in a Cross.toml file. For example if you’re targeting Raspberry Pi OS Lite 64-bit, you can use something like this:

August 27, 2019 - If this is not done, a error: linker cc not found message shows up when trying to compile an executable for that target. To create a Rust “Hello World” program, simply make a new folder (in this case I call it rs-hello) and let cargo do the rest of the work for you. cargo init cargo build --target=armv7-unknown-linux-gnueabihf · Now there is an executable that can be copied and executed on the remote Raspberry Pi.

Cross-Compiling Rust for Raspberry Pi - CodeBlueprint
November 27, 2025 - Even this tiny example should have some issues during cross-compilation: the v4l crate, bindgen, and the need for the correct libclang inside the build environment. You can easily wire the toolchain manually. It usually starts like this: sudo apt install gcc-aarch64-linux-gnu rustup target add aarch64-unknown-linux-gnu

We have rustup now.
$ rustup target add arm-unknown-linux-gnueabihf
$ sudo apt-get install gcc-arm-linux-gnueabihf
$ echo '[target.arm-unknown-linux-gnueabihf]' >> ~/.cargo/config
$ echo 'linker = "arm-linux-gnueabihf-gcc"' >> ~/.cargo/config
$ cd <project dir>
$ cargo build --target=arm-unknown-linux-gnueabihf

The Rust compiler is not distributed as a cross-compiler for the Raspberry Pi, so it needs to be compiled as a cross compiler with rpi dev tools.
Get rpi dev tools -
git clone https://github.com/raspberrypi/tools.git ~/pi-toolsget rust compiler from mozilla git repo and add rpi tools to the path
export PATH=~/pi-tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin:$PATHLook for rusty-pi dir on your home
./configure --target=arm-unknown-linux-gnueabihf --prefix=$HOME/rusty-pi && make && make installConsidering helloworld.rs ->
% ~/pi-rust/bin/rustc --target=arm-unknown-linux-gnueabihf -C linker=arm-linux-gnueabihf-g++ helloworld.rs
It will produce an executable.
