【SDL的编程】VC环境搭建

SDL（simple DirectMedia Layer）是一个可跨平台的开源库，最近由于自己的兴趣，就把它windosXP下的环境搭建了下。

PC：Mircrosoft Windows XP Service Pack3

Platform：Mircrosoft Visual C++ 6.0

SourceCode：SDL-devel-1.2.14-VC6.zip

步骤

    1. 解压SDL-devel-1.2.14-VC6.zip.将解压后的lib文件夹里把SDL.lib SDLmain.lib拷贝到VC6.0安装目录的lib文件夹下面。

    2. 将SDL.dll拷贝到系统盘的WINDOWS/SYSTEM32目录下（如果你要将之后生成的SDL应用程序转移到其他没有配置SDL环境的机器上用的话，请将SDL.dll一起拷贝）。

    3. 在VC6.0安装目录的include文件夹下面新建一个SDL的目录，并将SDL-devel-1.2.14-VC6.zip解压后的include里的文件拷贝到这个SDL目录下面。

    4. 打开VC6,新建一个project->win32 Application.打开project目录下面的那个setting，选中C/C++，Category里选中Code Generation，Use run-time library使用Multithread DLL.

    5. 继续在上面的setting中选中Link，Category里选中input，在Object/library modules中填入SDL.lib SDLmain.lib

    6. 在VC项目中新建一个cpp，并添加到项目中，编译，运行.

测试代码

#include <stdlib.h>
#include "SDL/SDL.h"

SDL_Surface *screen;

void render()
{        
     // Lock surface if needed
     if (SDL_MUSTLOCK(screen))    
         if (SDL_LockSurface(screen) < 0)    
             return;

     // Ask SDL for the time in milliseconds
     int tick = SDL_GetTicks();

     // Declare a couple of variables
     int i, j, yofs, ofs;

     // Draw to screen
    yofs = 0;
     for (i = 0; i < 480; i++)
    {
         for (j = 0, ofs = yofs; j < 640; j++, ofs++)
        {
            ((unsigned int*)screen->pixels)[ofs] = i * i + j * j + tick;
        }
        yofs += screen->pitch / 4;
    }

     // Unlock if needed
     if (SDL_MUSTLOCK(screen))    
        SDL_UnlockSurface(screen);

     // Tell SDL to update the whole screen
    SDL_UpdateRect(screen, 0, 0, 640, 480);        
}


// Entry point
int main( int argc, char *argv[])
{
     // Initialize SDL's subsystems - in this case, only video.
     if ( SDL_Init(SDL_INIT_VIDEO) < 0 )    
    {
        fprintf(stderr, "Unable to init SDL: %s\n", SDL_GetError());
        exit(1);
    }

     // Register SDL_Quit to be called at exit; makes sure things are
     // cleaned up when we quit.
    atexit(SDL_Quit);
        
     // Attempt to create a 640x480 window with 32bit pixels.
    screen = SDL_SetVideoMode(640, 480, 32, SDL_SWSURFACE);
    
     // If we fail, return error.
     if ( screen == NULL )    
    {
        fprintf(stderr, "Unable to set 640x480 video: %s\n", SDL_GetError());
        exit(1);
    }

     // Main loop: loop forever.
     while (1)
    {
         // Render stuff
        render();

         // Poll for events, and handle the ones we care about.
        SDL_Event event;
         while (SDL_PollEvent(& event))    
        {
             switch ( event.type)    
            {
             case SDL_KEYDOWN:
                 break;
             case SDL_KEYUP:
                 // If escape is pressed, return (and thus, quit)
                 if ( event.key.keysym.sym == SDLK_ESCAPE)
                     return 0;
                 break;
             case SDL_QUIT:
                 return(0);
            }
        }
    }
     return 0;
