Zig Cross-Compilation

Use this skill when building for different targets, creating release builds, or targeting WebAssembly/embedded platforms.

When to Use This Skill

• Cross-compiling for different architectures (ARM, RISC-V, x86)
• Targeting WebAssembly (WASM/WASI)
• Building freestanding binaries (no OS)
• Choosing build modes (Debug, ReleaseFast, ReleaseSafe, ReleaseSmall)
• Creating portable static binaries
• Targeting embedded systems

Cross-Compilation Basics

Zig is a cross-compiler out of the box — no external toolchains needed:
