Compiling

Most recently built on Zig 0.10.0-dev.1741+d2681d253

Dependencies

• SDL.zig
  • SDL2
• zig-clap
• known-folders
• bitfields.zig

bitfields.zig from 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 (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/.
