A Build Script in Zig

Your project's build is not a config file in another language. It is a real Zig program named build.zig that you can read and debug. 🏗️

It Starts with build

Every build.zig exposes one entry point: a public build function. Zig calls it to discover what your project should produce.

pub fn build(b: *std.Build) void {
    _ = b;
}

The Builder Object

That single parameter b is a *std.Build. It is the builder: every artifact and step you want is created through it.

b: *std.Build

Import the Standard Library

Like any Zig file, build.zig pulls in std at the top so you can reach std.Build and its helper types.

const std = @import("std");

Describe, Don't Run

The build function does not compile anything itself. It describes a graph of steps and artifacts that Zig then executes.

Pick the Target

Use standardTargetOptions to let the command line choose which OS and CPU you build for, defaulting to your own machine.

const target = b.standardTargetOptions(.{});

Pick the Optimize Mode

Pair it with standardOptimizeOption so users pass Debug or ReleaseFast on the command line instead of editing the file.

const optimize = b.standardOptimizeOption(.{});

Add an Artifact

Inside build you create things to compile, like an executable. Each artifact you add becomes a node in the build graph.

Run It with zig build

From the project root, the command zig build finds build.zig, calls your build function, and executes the resulting graph.

zig build

It Is Just Code

Because build.zig is ordinary Zig, you can use variables, conditions, and loops to shape the build any way you need.

One File, Whole Project

This one file is the source of truth for your whole project: targets, modes, artifacts, and steps all live in build.zig. ✅

Quick Check

Recall what Zig looks for when you run the build.

Recap

You saw that build.zig is a Zig program with a public build function taking a *std.Build, where you set target, optimize, and artifacts. 🎯
