Zig cross-compilation skill. Use when cross-compiling Zig programs to different targets, using Zig's built-in cross-compilation for embedded, WASM, Windows, ARM, or using zig cc to cross-compile C code without a system cross-toolchain. Activates on queries about Zig cross-compilation, zig target tri

Zig Cross Compilation Purpose Guide agents through Zig's built in cross compilation: target triple selection, CPU feature targeting, zig cc for cross compiling C projects, embedded bare metal targets, and WASM output — all without requiring a system cross toolchain. Triggers "How do I cross compile a Zig program for ARM?" "How do I build Zig for a different OS?" "How do I use Zig to cross compile C code for another platform?" "How do I build Zig for embedded/bare metal?" "How do I target WebAssembly with Zig?" "What Zig target triple do I use for Raspberry Pi?" Workflow 1. Zig's native cross compilation Zig has cross compilation built in — no cross toolchain, no Docker, no sysroot needed for pure Zig code: 2.
