Win7 MinGW环境测试SDL2.0.3

下载MinGW版的文件

http://www.libsdl.org/release/SDL2-devel-2.0.3-mingw.tar.gz

解压放到mysys下面

运行Makefile

mysys的include目录加入了SDL2的头文件目录

lib目录加入了libSDL2.a等文件

复制一份bin目录下的SDL2.dll以备后用

然后复制mysys的indluce目录下的SDL2目录和lib目录下的几个SDL2.a到MinGW的include和lib目录一份

编译IDE依然使用Codeblocks，设置同Ubuntu

不同的是windows环境源码要加上一句

#undef main

这个在Visual Studio中使用SDL2也要加这句

 #include <iostream>
 #include <SDL2/SDL.h>

 #define WIDTH 640
 #define HEIGHT 480
 #define BPP 4
 #define DEPTH 32

 using namespace std;

 #undef main

 int main(int argc, char* argv[])
 {
     SDL_Surface *screen;
     SDL_Event event;

     int keypress = ;
     int h = ;

     if (SDL_Init(SDL_INIT_EVERYTHING) == - ) {
         cout << "error: " << SDL_GetError() << endl;
         return ;
     }

     SDL_Window* window = SDL_CreateWindow("hello", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, , , SDL_WINDOW_SHOWN);
     if (window == NULL){
         cout << "Error: " << SDL_GetError() << endl;
         return ;
     }
     SDL_Renderer* renderer = SDL_CreateRenderer(window, -, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
     if (renderer == NULL){
         cout << "Error: " << SDL_GetError() << endl;
         return ;
     }

     SDL_Surface* surface = SDL_LoadBMP("bk.bmp");
     SDL_Texture* texture = SDL_CreateTextureFromSurface(renderer, surface);
     SDL_FreeSurface(surface);

     SDL_RenderClear(renderer);                  //清除屏幕
     SDL_RenderCopy(renderer, texture, , );    //把texture画到renderer上
     SDL_RenderPresent(renderer);

     while(!keypress)
     {
         //DrawScreen(screen, h++);
         while(SDL_PollEvent(&event))
         {
             switch (event.type)
             {
                 case SDL_QUIT:
                     keypress = ;
                     break;
                 case SDL_KEYDOWN:
                     keypress = ;
                     break;
             }
         }
     }

     SDL_Quit();
     return ;
 }

编译可能出现

winapifamily.h: No such file or directory

搜索到这贴，说是SDL2.0.3的一个bug，下载修正的SDL_platform.h文件替换

http://stackoverflow.com/questions/22446008/winapifamily-h-no-such-file-or-directory-when-compiling-sdl-in-codeblocks

https://hg.libsdl.org/SDL/raw-file/e217ed463f25/include/SDL_platform.h

运行提示缺少SDL2.dll

把之前那个SDL2.dll放到测试程序目录下

D:\Program Files\CBProjects\SDL2Test\bin\Debug

运行成功

下一步考虑怎么搞个跨平台工程
