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
