## Compiling
|
|
Most recently built on Zig [0.10.0-dev.2978+803376708](https://github.com/ziglang/zig/tree/803376708)
|
|
|
|
### Dependencies
|
|
* [SDL.zig](https://github.com/MasterQ32/SDL.zig)
|
|
* [SDL2](https://www.libsdl.org/download-2.0.php)
|
|
* [zig-clap](https://github.com/Hejsil/zig-clap)
|
|
* [known-folders](https://github.com/ziglibs/known-folders)
|
|
* [`bitfields.zig`](https://github.com/FlorenceOS/Florence/blob/f6044db788d35d43d66c1d7e58ef1e3c79f10d6f/lib/util/bitfields.zig)
|
|
|
|
`bitfields.zig` from [FlorenceOS](https://github.com/FlorenceOS) is included under `lib/util/bitfield.zig`.
|
|
|
|
Use `git submodule update --init` from the project root to pull the git submodules `SDL.zig`, `zig-clap`, and `known-folders`
|
|
|
|
Be sure to provide SDL2 using:
|
|
* Linux: Your distro's package manager
|
|
* MacOS: ¯\\\_(ツ)_/¯
|
|
* Windows: [`vcpkg`](https://github.com/Microsoft/vcpkg) (install `sdl2:x64-windows`)
|
|
|
|
`SDL.zig` will provide a helpful compile error if the zig compiler is unable to find SDL2.
|
|
|
|
Once you've got all the dependencies, execute `zig build -Drelease-fast`. The executable is located at `zig-out/bin/`.
