• msys2-SDL2-Setup.md

安裝需要的 package:

pacman -S git mingw-w64-x86_64-toolchain mingw64/mingw-w64-x86_64-SDL2 mingw64/mingw-w64-x86_64-SDL2_mixer mingw64/mingw-w64-x86_64-SDL2_image mingw64/mingw-w64-x86_64-SDL2_ttf mingw64/mingw-w64-x86_64-SDL2_net mingw64/mingw-w64-x86_64-cmake make

測試:

$ sdl2-config --cflags --libs
-IC:/msys64/ucrt64/include/SDL2 -Dmain=SDL_main
-LC:/msys64/ucrt64/lib -lmingw32 -mwindows -lSDL2main -lSDL2

用上面ref 的 example:

#include &;t;stdio.h>
#include <SDL2/SDL.h>

const int WIDTH = 800, HEIGHT = 600;

int main(int argc, char *argv[]) {
  SDL_Window *window;
  SDL_Renderer *renderer;
  if(SDL_Init(SDL_INIT_EVERYTHING) < 0) {
    printf("SDL_Init failed: %s\n", SDL_GetError());
    return 1;
  }

  window = SDL_CreateWindow("Hello, World!",
                                        SDL_WINDOWPOS_UNDEFINED,
                                        SDL_WINDOWPOS_UNDEFINED,
                                        WIDTH, HEIGHT,
                                        SDL_WINDOW_ALLOW_HIGHDPI);
  if(window == NULL) {
    printf("Could not create window: %s\n", SDL_GetError());
    return 1;
  }
  
  renderer = SDL_CreateRenderer(window, -1, 0);
  SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255);
  SDL_RenderClear(renderer);

  SDL_RenderPresent(renderer);
  
  SDL_Event event;
  while(1) {
    if(SDL_PollEvent(&event)) {
      if(event.type == SDL_QUIT) {
        break;
      }
    }
  }

  SDL_DestroyWindow(window);

  SDL_Quit();
  return 0;
}

build:

$ gcc -o testsdl testsdl.c `sdl2-config --cflags --libs`
