SDL编程

一、简介

SDL是一个用C编写的跨平台的多媒体库，它通过OpenGL和Direct3D，提供了针对音频、视频、键盘、鼠标、控制杆及3D硬件的低级别的访问接口。它在MPEG播放软件、模拟器以及许多游戏中得到广泛的应用，其中包含了获得大奖的“文明：权力的呼唤”的Linux 版本。

二、编译安装

参考：

http://toutiao.com/a4450957327/

 

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

tar -zxvf SDL2-2.0.3.tar.gz

cd SDL2-2.0.3

mkdir build

cd build

../configure

make

make install

 

三、使用实例

example1.c

//Toggle line numbers 

#include "SDL.h"



int main(int argc, char* argv[])

{

        SDL_Window* window;

        SDL_Renderer* renderer;



        // Initialize SDL.

        if (SDL_Init(SDL_INIT_VIDEO) < 0)

                return 1;



        // Create the window where we will draw.

        window = SDL_CreateWindow("SDL_RenderClear",

                        SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,

                        512, 512,

                        0);



        // We must call SDL_CreateRenderer in order for draw calls to affect this window.

        renderer = SDL_CreateRenderer(window, -1, 0);



        // Select the color for drawing. It is set to red here.

        SDL_SetRenderDrawColor(renderer, 255, 0, 0, 255);



        // Clear the entire screen to our selected color.

        SDL_RenderClear(renderer);



        // Up until now everything was drawn behind the scenes.

        // This will show the new, red contents of the window.

        SDL_RenderPresent(renderer);



        // Give us time to see the window.

        SDL_Delay(5000);



        // Always be sure to clean up

        SDL_Quit();

        return 0;

}

编译

gcc example1.c -o example1 -I/root/workspace/exercise/languages/c/graph/sdl/SDL2-2.0.3/include -L/root/workspace/exercise/languages/c/graph/sdl/SDL2-2.0.3/build/build/.libs -lSDL2
