本文主要向大家介绍了VC编程之【SDL的编程】VC环境搭建，通过具体的内容向大家展示，希望对大家学习VC编程有所帮助。

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;

}
