本文详细介绍了如何在MinGW环境下安装并配置SDL和SDL_image库，并提供了一个简单的示例程序来演示如何使用这些库加载和显示图像。

1、下载sdl库：http://www.libsdl.org/release/SDL-devel-1.2.15-mingw32.tar.gz

2、下载sdl_image库： http://www.libsdl.org/projects/SDL_image/release/SDL_image-devel-1.2.12-VC.zip

3、在mingw32/include下建立SDL文件夹。把sdl库include中的文件全部copy到这里

4、把sdl的lib下文件全部copy到mingw32的lib下

5、把sdl_image库中的inlcude/sdl_image.h放到刚才建立的文件夹下

6、把sdl_image库中的lib中的dll文件全部copy到mingw32d的lib中

7、把sdl_imagelib中的dll和sdl中的sdl.dll放到你编译的exe文件目录

8、编译指令

gcc -o demo4.exe(输出文件名) demo4.c(源文件名) -lmingw32 -lSDL_image -lSDLmain -lSDL

测试代码（请在该目录放一个tt.png图片，随便。自己网上找了）：

#include<stdio.h>
#include "SDL/SDL.h"
#include "SDL/SDL_image.h"
SDL_Surface *screen;


void video_init(){  //游戏图形模式初始化
	if(SDL_Init(SDL_INIT_VIDEO)){
		fprintf(stderr,"Can't init SDL:%s\n",SDL_GetError());
		exit(1);
	}
	screen=SDL_SetVideoMode(640,480,16,SDL_SWSURFACE);
	if(screen==NULL){
		fprintf(stderr,"Can't set mode 640x480:%s\n",SDL_GetError());
		exit(1);
	}
	atexit(SDL_Quit);
	SDL_ShowCursor(0);//关闭鼠标显示
}

SDL_Surface *loadIMG(const char *fileName){
	SDL_Surface *img;
	img = IMG_Load(fileName);
	if(img == NULL)  
    {  
        fprintf(stderr,"Could not load %s: %s",fileName,SDL_GetError());  
        exit(1);  
    }  
    return img;  
}

SDL_Surface *loadBMP(char *fileName)            //加载bmp图片  
{  
    SDL_Surface *bmp;  
    bmp = SDL_LoadBMP(fileName);  
    if(bmp == NULL)  
    {  
        fprintf(stderr,"Could not load %s: %s",fileName,SDL_GetError());  
        exit(1);  
    }  
    return bmp;  
}  

int main(int argc, char* argv[]){
	if(SDL_Init(SDL_INIT_EVERYTHING)==-1){
		printf("error..\n");
	}else{
		printf("ok\n");
		
		video_init();
		
		SDL_Surface *img;
		img=loadIMG("tt.png");
			
		while (1){
			// Poll for events, and handle the ones we care about.
			SDL_Rect dest;
			dest.x=100;
			dest.y=100;
			dest.w=200;
			dest.h=200;
			
			SDL_Color color;
			color.r=255;
			color.g=0;
			color.b=0;

			
			SDL_FillRect(screen, &screen->clip_rect, SDL_MapRGB(screen->format,0xFF,0xFF,0xFF));
			SDL_FillRect(screen, &dest, SDL_MapRGB(screen->format,0,0,0xFF));
			
			dest.x=200;
			dest.y=200;
			dest.w=200;
			dest.h=200;
			SDL_BlitSurface(img, &screen->clip_rect, screen,&dest);

			
			SDL_Flip(screen);
			SDL_Event event;
			while (SDL_PollEvent(&event)){
				if(event.type==SDL_KEYDOWN){
					int key = event.key.keysym.sym;
					printf("%d\n",key);
					if(key==SDLK_ESCAPE){
						printf("%d\n",1000);
						SDL_Quit();
						exit(1);
					}else if(key==SDLK_UP){
						printf("up\n");
					}else if(key==SDLK_DOWN){
						printf("down\n");
					}else if(key==SDLK_LEFT){
						printf("left\n");
					}else if(key==SDLK_RIGHT){
						printf("right\n");
					}
				}else if(event.type==SDL_QUIT){
					printf("%d\n",1000);
					SDL_Quit();
					exit(1);
				}
			}
		}

	return 0;
