Build & Run Instructions

Prerequisites

• Julia (recommended: 1.10 or below)
• StaticCompiler.jl and StaticTools.jl Julia packages
• C compiler (e.g., gcc)
• SDL2 development libraries (for desktop build)
• Emscripten SDK (for web build)

1. Install Julia dependencies

using Pkg
Pkg.add(["StaticCompiler", "StaticTools"])

2. Build for Web (WASM)

• Make sure Emscripten is installed and emcc is in your PATH. Instructions here: https://emscripten.org/docs/getting_started/downloads.html
• Run:

# Remember, julia 1.10 or below
julia compile_game.jl web

• Output will be in the game_wasm/ directory:
  • game.js, game.wasm
• You can serve this directory with any static web server (e.g., python3 -m http.server)

3. Build for Desktop (Linux, macOS, Windows)

• Make sure SDL2 shared libraries are available in SDLCalls/lib or libs (see below).
• Run:

# Remember, julia 1.10 or below
julia compile_game.jl desktop

• Output will be in the game_desktop/ directory:
  • Linux/macOS: game
  • Windows: game.exe

Local SDL2 Libraries

• Place your SDL2 .so/.dylib/.dll files in SDLCalls/lib or libs.
• On Linux, ensure you have both libSDL2.so and libSDL2-2.0.so.0 (symlink if needed):

  ln -sf libSDL2-2.0.so.0 SDLCalls/lib/libSDL2.so

Running the Desktop Build

• On Linux/macOS, you can run:

  ./game_desktop/game

• If you encounter missing library errors, ensure the libraries are present and rpath is set. You can also try:

  LD_LIBRARY_PATH=SDLCalls/lib:libs ./game_desktop/game
