Destinos y la terna -target

Zig ships every supported target inside the compiler, so cross-compilation needs no extra toolchains or downloads to begin.

You name a target with a triple: it spells out the CPU architecture, the operating system, and the ABI in one string.

Read a triple left to right as arch-os-abi. Each part narrows down exactly which binary the compiler should produce.

You select a target on the command line with the -target flag, and Zig builds for that machine instead of your own.

The first field is the architecture, like x86_64, aarch64, or riscv64. It decides the instruction set of the output.

The middle field is the operating system, such as linux, macos, or windows. It shapes system calls and file formats.

The last field is the ABI, like gnu, musl, or msvc. It picks the C library and calling conventions to match.

Not sure which triples exist? Ask Zig to print them all. zig targets dumps the supported architectures, OSes, and ABIs.

With no -target flag, Zig builds for the native triple: the same arch, OS, and ABI as the machine you are on.

You can leave fields off and Zig fills in a sensible default. x86_64-linux works because the ABI is chosen for you.

You can refine the architecture with a CPU model after a plus sign, asking Zig to use features of a specific processor.

Recall the order of fields inside a target triple.

You learned that a target triple names arch, OS, and ABI, and that -target lets Zig build for any of them. 🌍
