### 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)
|
2022-03-01 02:10:32 +00:00
|
|
|
* [`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`.
|
|
|
|
|
|
|
|
|
|
`SDL.zig` and `zig-clap` are git submodules you can init using `git submodule update --init` from your terminal.
|
|
|
|
|
|
|
|
|
|
On Linux, be sure to have SDL2 installed using whatever package manager your distro uses.
|
|
|
|
|
|
|
|
|
|
On Windows, it's easiest if you use [`vcpkg`](https://github.com/Microsoft/vcpkg) to install `sdl2:x64-windows`. If not,
|
|
|
|
|
`SDL2.zig` will provide a helpful compile error which should help you get what you need.
|
|
|
|
|
|
|
|
|
|
On macOS? ¯\\\_(ツ)_/¯ I hope it isn't too hard to compile though.

Once you've got all the dependencies, run `zig build -Drelease-fast`. The executable is located at `zig-out/bin/`.
