Standalone cross compilation Rust Shell

A standalone nix shell file to setup Rust cross-compilation toolchain.

This file does not have any additional dependencies and is completely self-sufficient. You can use the nix-shell command and get the working cross-compilation toolchain. By default, it produces completely static binaries, which can be placed into the Alpine Linux container as is.

Usage:

nix-shell ./shell-rust-cross.nix

Tips:

  • You can enable a binary cache by running the command: nix-shell -p cachix --run "cachix use nixpkgs-cross-overlay"
  • If you have compilation issues, try to add --pure argument to the nix-shell.
  • You can override the default cross-compilation target by passing the argument to nix-shell: --arg crossSystem '{ config = "x86_64-unknown-linux-gnu"; isStatic = false; useLLVM = false; }'
  • Also, you can set crossSystem argument to the null and get a nice native shell.
