SDL的VC环境搭建

来源：互联网发布：exec linux 编辑：程序博客网时间：2024/05/21 13:50

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++)
        {
            ((unsignedint*)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_Eventevent;
       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;
}
