DirectShow VC6.0 开发环境的搭建今天要用DirectShow做一个音频采集程序，结果遇到的第一个问题便是开发环境的搭建，需要几步准备。1）下载支持DirectShow的SDK2）将SDK中的include和lib目录配置到VC6.0下（一般SDK在安装过程中会自己配置）3）编译SDK中samples中提供的项目，得到Strmbasd.lib winmm.lib库文件，这个要在新建的DirectShow工程中引用阅读详情

[1] 请确保您的机子上已经安装了VS 2005和DirectX 9.0b SDK。DX9.0 SDK的下载地址就不写了，自己在网上找吧！（我的DX9.0安装在D盘根目录下）

[2] 首先编译SamplesC++DirectShowBaseClasses目录下的baseclasses.sln以得到两个库文件（strbase.lib和strmbase.lib）。以下介绍的主要是如何修改编译中的错误，这也是众多文章中没有叙述的部分。自己写的，有些啰嗦，请原谅哦！

进入DirectShow的安装目录，找到SamplesC++DirectShowBaseClasses，双击baseclasses.sln打开该解决方案。首先看到的会是Visual Studio的转换向导，不用管它，直接Next到Finish。

点击F5，调试运行，你会见到下面的错误（至少我编译的时候就是这样的结果）：

    1>------ Build started: Project: BaseClasses, Configuration: Debug Unicode Win32 ------

没办法，改错。（网上老外的文章中说过，不过也不明白什么意思！）

双击1>D:Program FilesMicrosoft Visual Studio 8VCPlatformSDKincludewinnt.h(222) : error C2146: syntax error : missing ';' before identifier 'PVOID64' 跳转到出错的位置。

你会见到错误语句：typedef void * POINTER_64 PVOID64;

这样的定义，VS2005中是不支持的。将其修改为两条语句：

    #define POINTER_64 __ptr64

    typedef void *PVOID;
    typedef void *POINTER_64 PVOID64;

然后调试运行，会发现还有1条错误：

      1>------ Build started: Project: BaseClasses, Configuration: Debug Unicode Win32 ------

      1>BaseClasses - 1 error(s), 1 warning(s)
      ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

只有继续改啦！双击1>d:DXSDKSamplesC++DirectShowBaseClassesctlutil.h(278) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int 跳转到出错的位置。

你会见到错误语句：operator=(LONG);

只是没有返回值嘛！给它加一个就行了，将其改为：LONG operate=(LONG);

再次调试运行，哇塞！更多错误：

有错就改啦！双击1>.wxdebug.cpp(567) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int 跳到出错位置。

你会见到出错语句：static g_dwLastRefresh = 0;

静态类型变量有这么定义的吗？总得给个类型吧！将其改为：static DWORD g_dwLastRefresh = 0;为什么类型指定为DWORD？看程序中的语句就明白了——保证相同类型的变量进行运算。

错误少了一个哦！继续努力！双击1>.winutil.cpp(2104) : error C2065: 'Count' : undeclared identifier跳到出错位置。

你会见到出错语句：for (Count = 0;Count < Result;Count++) {

Count没有定义？看该语句上面的语句：

     for (UINT Count = 0;Count < Result;Count++) {
       if (SystemEntries[Count].peRed != pEntry[Count].peRed ||
SystemEntries[Count].peGreen != pEntry[Count].peGreen ||
          SystemEntries[Count].peBlue != pEntry[Count].peBlue) {
               bIdentityPalette = FALSE;
            }
       }

// And likewise compare against the last ten entries

Result = GetSystemPaletteEntries(hdc,PalHiStart,PalLoCount,SystemEntries);

看到了吧！Count是在循环体内定义的变量，出了循环之后就“生命”over了。所以将它定义到外面去。将以上的语句改为：

UINT Count = 0;

        for (Count = 0;Count < Result;Count++) {
            if (SystemEntries[Count].peRed != pEntry[Count].peRed ||
                  SystemEntries[Count].peGreen != pEntry[Count].peGreen ||
                    SystemEntries[Count].peBlue != pEntry[Count].peBlue) {
                        bIdentityPalette = FALSE;
           }
         }

// And likewise compare against the last ten entries

Result = GetSystemPaletteEntries(hdc,PalHiStart,PalLoCount,SystemEntries);

再次调试运行：

        1>------ Build started: Project: BaseClasses, Configuration: Debug Unicode Win32 ------
        1>Compiling...
        1>winutil.cpp

        1>BaseClasses - 1 error(s), 0 warning(s)
        ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

不错哦！错误剩下一个了！再改，双击1>.outputq.cpp(664) : error C2065: 'iDone' : undeclared identifier
跳到出错位置。

你会见到出错语句：*nSamplesProcessed = iDone - iLost;

iDone没有定义？OK，继续看它上面的语句：

// Loop processing the samples in batches

       LONG iLost = 0;
       for (long iDone = 0;
             iDone < nSamples || (m_nBatched != 0 && m_bSendAnyway);
            ) {

// ...

同样的，将iDone的定义放到循环体的外面去，改为：

// Loop processing the samples in batches

LONG iLost = 0;

       long iDone = 0;
       for (iDone = 0;
             iDone < nSamples || (m_nBatched != 0 && m_bSendAnyway);
            ) {

// ...

改完了以后，再次调试运行：

总算见到succeeded了，呵呵！你调出来了吗？
