Zig Build System — Build.zig, Dependencies, and Cross-Compilation

DodaTech Updated 2026-06-29 1 min read

In this tutorial, you will learn about Zig Build System. We cover key concepts, practical examples, and best practices to help you master this topic.

Zig's build system is part of the language itself — no CMake or Make required.

// build.zig
const std = @import("std");

pub fn build(b: *std.Build) void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});

    const exe = b.addExecutable(.{
        .name = "myapp",
        .root_source_file = .{ .path = "src/main.zig" },
        .target = target,
        .optimize = optimize,
    });

    b.installArtifact(exe);

    const run_cmd = b.addRunArtifact(exe);
    run_cmd.step.dependOn(b.getInstallStep());
}
