Ubuntu-14.04.3下SDL2测试

最近突然蛋痛想入门Linux，想写个跨平台的游戏，各种坑，备忘，稍微记点笔记。

主要参考这个文章

buntu14.04下C++开发SDL2应用

下载与安装

到http://www.libsdl.org/下载

http://www.libsdl.org/release/SDL2-2.0.3.zip

解压后

./configure
make
sudo make install

检查

头文件：cd /usr/local/include/SDL2

库位置：cd /usr/local/lib

加入环境变量中

sudo vim /etc/ld.so.conf  #修改系统共享库搜索路径

在第一行增加

include /usr/local/lib

再运行命令：

sudo ldconfig

CodeBlocks中测试Hello world

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

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

 using namespace std;

 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 ;
 }
