Zig Cross

This guide walks you through Zig's built-in cross-compilation, which lets you target ARM, Windows, macOS, embedded systems, and WebAssembly without installing system toolchains or messing with Docker. It covers target triple selection (like aarch64-linux-gnu for Raspberry Pi or thumbv7em-freestanding-eabihf for Cortex-M4), CPU feature flags, and using zig cc to cross-compile C code. The embedded and WASM sections are solid if you're working bare metal or targeting browsers. Honestly, the fact that you can build a Windows binary from Linux with one flag is pretty great. Most useful when you need to ship binaries for multiple platforms from a single dev machine.
