CSDN今日推荐一个学生，各种尝试，记录于此……
SDL在dev-c++的配置记录
！！！这个方法有些问题，原因未知，请不要使用
由于一些原因需要用到SDL这个库，把自己学习的过程记录一下。
我的环境，Dev-C++的版本:5.9.2，SDL的版本:2.0.3。
其中的一些操作的原因我也不太清楚为什么，只知道这样可行，如果哪位知道还请留言解惑一下。
一、文件下载
在sdl官网上下载development libraries(MinGW)
http://www.libsdl.org/release/SDL2-devel-2.0.3-mingw.tar.gz
二、将下载的文件解压后目录为
由于我的是64位系统，所以将x86_64-w64-mingw32文件夹下的include和lib文件夹复制到Dev-C++目录下相应的位置，再将SDL根目录下lib\x64里的SDL2.dll文件复制到C:\Windows\System32中(这里为什么不复制到sysWOW64文件夹下？)
三、编译测试
在Dev-C++中新建一个空工程，复制以下代码
#include &stdio.h&
#include "SDL2/SDL.h"
int main( int argc, char* args[] )
if (SDL_Init( SDL_INIT_EVERYTHING ) != 0){
printf("SDL_Init Error: %s", SDL_GetError());
SDL_Quit();
system("pause");
} 然后在 项目-&项目属性-&参数-&链接中添加-lmingw32 -lSDL2main -lSDL2
编译无错即可
