# sokol-zig: Zig bindings for the sokol single-header libraries

> sokol-zig gives Zig projects the sokol set of cross-platform libraries, graphics, audio, input and timing, through the standard Zig package manager. The README is candid about the catch, the bindings can fall behind when Zig makes a breaking change, and it targets Zig 0.16.0 or newer.

## sokol as a Zig package, and the version caveat

sokol-zig provides Zig bindings for the sokol headers, and the sokol project itself is a set of cross-platform libraries. The point of the bindings is that you get the whole stack, graphics, audio, input and timing, through the ordinary Zig package manager rather than through a vendored copy of headers.

The version requirement is stated at the top. It is for Zig version 0.16.0 or newer.

The README then names the risk in one sentence, and it is worth taking at face value. In case of breaking changes in Zig, the bindings might fall behind. The author asks you to ping them via a GitHub issue or, better, to provide a pull request. This is a single-maintainer binding layer tracking a language that changes its build system and language features regularly, and the honest characterisation is that the two move together at the speed of the slower one.

There are no GitHub releases in the repository, so the Zig package manager dependency hash is the pinning mechanism rather than a version tag. The licence is Zlib, and the project is written in C, in the sense that it wraps C headers.

The related projects give a sense of what the bindings are used for. There is pacman.zig, chipz emulators, and a Dear ImGui sample project built on top of sokol-zig, which is the clearest evidence that the package works as a foundation for a real application rather than only as a demo.

## Platform prerequisites that Linux users have to install by hand

The build prerequisites section is honest about what the base system does not give you.

On Linux you need a couple of development packages. With Ubuntu as the example:

```
sudo apt install xorg-dev libasound-dev
```

The X11 development package is for the windowing system and libasound-dev is for ALSA, which is the audio backend. If you use EGL instead of GLX you also need the EGL development package, and if you use the experimental Vulkan backend you need the Vulkan development package along with the tools and validation layers:

```
sudo apt install libvulkan-dev vulkan-tools vulkan-validationlayers
```

The README says all other platforms should build out of the box, and the asymmetry is real: the Windows and macOS toolchains ship with the graphics and audio development files that Linux splits into packages.

The Vulkan situation has an extra wrinkle, and it is the kind that costs an afternoon. The experimental Vulkan backend now also supports Windows, but the build.zig has not been prepared for it, so to use it on Windows you need to install the Vulkan SDK and point the VULKAN_SDK environment variable at the Vulkan header and library stubs.

The samples add one more Linux dependency list, which is slightly different: libglu1-mesa-dev, mesa-common-dev, xorg-dev and libasound-dev, or generally the dev packages required for X11, GL and ALSA development.

## Building the samples, and the per-platform backend default

The samples are the quickest way to check that a build works, and there are around twenty of them covering the range of sokol.

```sh
# build all examples:
zig build examples
# build and run individual examples
zig build run-clear
zig build run-triangle
zig build run-quad
zig build run-bufferoffsets
zig build run-cube
zig build run-noninterleaved
zig build run-texcube
zig build run-offscreen
zig build run-instancing
zig build run-mrt
zig build run-saudio
zig build run-sgl
zig build run-sgl-context
zig build run-sgl-points
zig build run-debugtext
zig build run-debugtext-print
zig build run-debugtext-userfont
zig build run-shapes
```

You can also run zig build -l to get a list of build targets. The supported platforms are Windows, macOS, Linux with X11 and the web.

The backend selection is the interesting part, and it defaults to the native 3D API of the target. On macOS it is Metal, on Windows it is D3D11, and on Linux it is GL.

```
> zig build -Dgl=true run-clear
```

Forcing GL on macOS or Windows is a build option, and the experimental Vulkan backend has its own flag, -Dvulkan=true. The clear sample prints the selected backend to the terminal, which is a quick way to confirm what you actually got:

```
sokol-zig ➤ zig build -Dgl=true run-clear
Backend: .sokol.gfx.Backend.GLCORE33
```

There is a caveat on Vulkan. The README notes that Vulkan support is currently only supported on Linux, and that as of Zig 0.16.x there is an issue with the libvulkan.so DLL from the Vulkan SDK, while linking with the system Vulkan DLL appears to work.

## Web builds need a local Emscripten SDK

The web target is a separate build path with a separate prerequisite, and the README is specific about it.

First you install a local Emscripten SDK into the zig-pkg directory:

```sh
zig build install-emsdk
```

Then you build with the wasm32-emscripten target:

```sh
zig build examples -Dtarget=wasm32-emscripten
# or to build and run one of the samples
zig build run-clear -Dtarget=wasm32-emscripten
```

The stated limitation is that there is currently no build system functionality to update or delete the Emscripten SDK after this first install, and the workaround is to delete the zig-pkg subdirectory. Improving the Emscripten SDK integration with the Zig build system is planned for the future, which tells you the current state is a first cut.

The reason the Emscripten SDK is needed at all is that Emscripten must be used for linking, and to run the build result in a browser a special run step has to be created. That is why the web build script has to look different from a native one, which is the subject of the next section.

The samples themselves are in the examples/ directory, and the list is a good index of what sokol covers. There are blend.zig, bufferoffsets.zig, clear.zig, cube.zig, three debugtext variants, framebuffer.zig, two instancing examples including one with compute, math.zig, mrt.zig, noninterleaved.zig, offscreen.zig, quad.zig, saudio.zig, four sgl variants, shaders/, shapes.zig, texcube.zig, triangle.zig and vertexpull.zig.

## Consuming the package from your own build.zig

The integration story is the standard Zig package manager one, and the README gives both the manual and the automatic route.

The dependency is declared in a build.zig.zon file with at least a .sokol entry:

```zig
.{
    .name = "my_project",
    .version = "0.1.0",
    .paths = .{
        "src",
        "build.zig",
        "build.zig.zon",
    },
    .dependencies = .{
        .sokol = .{
            .url = "git+https://github.com/floooh/sokol-zig.git#[commit-hash]",
            .hash = "[content-hash]",
        },
    },
}
```

The easiest way to populate or update the dependency is a single command, which automatically uses the latest sokol-zig commit:

```
zig fetch --save=sokol git+https://github.com/floooh/sokol-zig.git
```

For a native-only project, the build.zig looks entirely vanilla, with the dependency pulled in and its module imported by name:

```zig
const std = @import("std");
const Build = std.Build;

pub fn build(b: *Build) !void {
    const target = b.standardTargetOptions(.{});
    const optimize = b.standardOptimizeOption(.{});
    const dep_sokol = b.dependency("sokol", .{
        .target = target,
        .optimize = optimize,
    });
```

Build options pass through to the dependency, so forcing the GL backend from your own project is the same flag on the dependency call:

```zig
const dep_sokol = b.dependency("sokol", .{
    .target = target,
    .optimize = optimize,
    // same as building sokol-zig with -Dgl=true
    .gl = true
});
```

The README notes this can be done with any build option declared in sokol-zig, so the option set is whatever the package exposes.

## Where sokol-zig is the wrong choice

The first wrong case is a team that does not want to track Zig's breaking changes. The README does not hide this, and it is not a small thing, because Zig's package manager hashes content, so a Zig release that changes the standard library can invalidate your dependency hashes and force a re-fetch across your whole project. The bindings are good, but they sit underneath a language whose build system is still moving.

The second is a project that has already chosen a graphics abstraction. sokol is deliberately small and low level, which is a virtue for a toolkit and a limitation for an application. If your team wants scene graphs, asset pipelines and shading systems, that is a different layer of software, and sokol-zig does not provide it.

The third is Linux without the development packages. The base system does not include the X11, GL and ALSA development files, and the list differs between the build prerequisites section and the samples section, which is a small sign of two different setups being documented. A CI image that assumes the packages are present will fail at the first build.

The fourth is Vulkan on Windows or on the web. The experimental backend does not support Windows in the build file, the web path is not described for Vulkan at all, and there is a known libvulkan.so issue with the Vulkan SDK on Zig 0.16.x where the system DLL works instead. The GL path is the reliable one.

The alternative worth weighing is the C library directly. sokol is a set of single-header C libraries, so you can call them from Zig through translate-c with no bindings package at all. You lose the Zig-idiomatic module and the build options, and you gain no dependency on a binding layer that can fall behind.

## Conclusion

Adopt sokol-zig if you want the sokol set of libraries in a Zig project and want the same source to build for Windows, macOS, Linux and the web without a build system per platform. Keep away if your team cannot absorb Zig's rapid breaking changes, because the README says plainly that the bindings might fall behind when Zig changes, and there is no tagged release in the repository to pin to. Before you build, install the platform development packages, since the Linux path needs X11, GL and ALSA dev packages that do not come with the base system, and check the backend selection because the default 3D API differs per platform, Metal on macOS, D3D11 on Windows and GL on Linux.

## FAQ

### What Zig version does sokol-zig need?

Zig version 0.16.0 or newer. The README also warns that in case of breaking changes in Zig the bindings might fall behind, and asks you to open an issue or a pull request if that happens.

### How do I build and run the sokol-zig samples?

Run zig build examples to build all of them, or zig build run-clear, run-triangle, run-cube and the other individual run targets. The supported platforms are Windows, macOS, Linux with X11 and the web, and zig build -l lists the available targets.

### Which 3D backend does sokol-zig use on each platform?

By default the backend is selected from the target platform: Metal on macOS, D3D11 on Windows and GL on Linux. You can force GL on macOS or Windows with the -Dgl=true build option, and the experimental Vulkan backend with -Dvulkan=true, though the README notes Vulkan is currently only supported on Linux.

### How do I add sokol-zig to my own Zig project?

Add a .sokol dependency to your build.zig.zon pointing at git+https://github.com/floooh/sokol-zig.git, or run zig fetch --save=sokol with the same URL to populate and update it automatically, then pull it into your build with b.dependency("sokol", ...) and import its module.
