make; make install 5.2.2. 步骤2.2：linux下编译执行1) 将源文件sdl_simple_game.cpp拷贝到linux主机2) 进行编译：g+ -o t sdl_simple_game.cpp L/usr/lib lSDL,生成可执行文件3) 执行 ,在命令行输入./t5.3. 步骤4：设计游戏代码 /The headers#include SDL/SDL.h#include SDL/SDL_image.h#include #include /Screen attributesconst int SCREEN_WIDTH = 721;const int SCREEN_HEIGHT = 721;const int SCREEN_BPP = 32;/The frames per secondconst int FRAMES_PER_SECOND = 10;/The dimenstions of the stick figureconst int FOO_WIDTH = 180;const int FOO_HEIGHT = 180;const int Begin=0;const int Run=1;const int End=2;bool flag44;
