A lightweight C-based raycasting engine inspired by the classic Wolfenstein 3D, built with SDL2 and SDL2_image.

• Wolfenstein 3D rendering
• Map drawing with textured walls
• Basic movement & camera rotation
• Configurable window size
• Proper cleanup on exit (frees textures, destroys renderer/window, calls SDL_Quit())

Make sure you have:

• SDL2
• SDL2_image
• gcc (or any C compiler)

Ubuntu/Debian:

sudo apt install libsdl2-dev libsdl2-image-dev

macOS (Homebrew):

brew install sdl2 sdl2_image

make clean

make
./game

When you quit the game, it:

• Frees all loaded textures
• Destroys the SDL renderer and window
• Calls SDL_Quit() to release resources

• SDL2/SDL.h: No such file or directory → Install SDL2 and SDL2_image, then check include paths. On macOS, you may need:

  make CFLAGS="-I/opt/homebrew/include/SDL2" LDFLAGS="-L/opt/homebrew/lib"

• Duplicate symbol linker errors → Ensure shared functions are declared in headers with extern and defined in exactly one .c file.
