Artifacts to Build
The things you compile are called artifacts: an executable you run, or a library other code links against. You declare them in build.zig. 📦
Add an Executable
Create a runnable program with addExecutable. You give it a name and the root source file that holds main.
const exe = b.addExecutable(.{
.name = "app",
});Point to the Root Module
The artifact needs a root_module built from your main file, plus the target and optimize values you chose earlier.
.root_module = b.createModule(.{
.root_source_file = b.path("src/main.zig"),
}),Carry Target and Optimize
That module also takes the target and optimize fields, so the executable honors whatever the command line requested.
.target = target,
.optimize = optimize,Install the Output
Creating an exe is not enough; tell Zig to place it in zig-out with installArtifact so the default build emits it.
b.installArtifact(exe);Where Outputs Land
Installed binaries appear under zig-out/bin by convention. Run zig build and look there for your freshly compiled program.
zig-out/bin/appAdd a Library
For reusable code, use addLibrary instead. It produces a library artifact others can import and link against.
const lib = b.addLibrary(.{
.name = "mathz",
});Static or Dynamic
A library can be static (baked into the caller) or dynamic (a shared file). You set linkage when you declare the library.
.linkage = .static,Link Library into Exe
Connect them so the exe can call the library's code: use linkLibrary to add the dependency edge.
exe.linkLibrary(lib);Need libc?
If your code calls C standard functions, request libc on the artifact with linkLibC so the right system library is linked.
exe.linkLibC();A Graph of Artifacts
Each artifact is a node; linking adds edges. Together they form the build graph Zig walks when you run the build. ✅
Quick Check
Recall which call actually emits a built binary into zig-out.
Recap
You declared artifacts with addExecutable and addLibrary, set their root module and target, then used installArtifact and linkLibrary to wire them. 🎯
