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
