使用Visual Studio.net 2005 编译 Microsoft Platform SDK\Samples\Multimedia\DirectShow\BaseClasses 的时候,
使用nmake ,
总是会出现一些编译过去的怪问题,

如:
环境:winxp SP2, Visual studio 8.0.5..., with .net framework 2.0.50727, Microsoft DirectX SDK (August 2007), and Microsoft Platform SDK (5.2.3790.1830.15.PlatformSDK_Svr2003SP1_rtm)

c:\Programme\Microsoft Platform SDK\Samples\Multimedia\DirectShow\BaseClasses\ctlutil.h(278) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

in ctlutil.h

private:
    //  Prevent bugs from constructing from LONG (which gets
    //  converted to double and then multiplied by 10000000
    COARefTime(LONG);
    operator=(LONG);
};

c:\Programme\Microsoft Platform SDK\Samples\Multimedia\DirectShow\BaseClasses\ctlutil.h(278) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

<- the line 278 referes to " operator=(LONG);"
================================================
on ctlutil.h, but I get another error C4430 in wxdebug.cpp

.\wxdebug.cpp(564) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

the line is:         static g_dwLastRefresh = 0;

I have no ideia which type g_dwLastRefresh should be.
the code block is as follows:
BOOL WINAPI DbgCheckModuleLevel(DWORD Type,DWORD Level)
{
    if(g_fAutoRefreshLevels)
    {
        // re-read the registry every second. We cannot use RegNotify() to
        // notice registry changes because it's not available on win9x.
        static g_dwLastRefresh = 0;
        DWORD dwTime = timeGetTime();
        if(dwTime - g_dwLastRefresh > 1000) {
            g_dwLastRefresh = dwTime;

            // there's a race condition: multiple threads could update the
            // values. plus read and write not synchronized. no harm
            // though.
            DbgInitModuleSettings(false);
        }
    }

and on winutil.cpp
.\winutil.cpp(2104) : error C2065: 'Count' : undeclared identifier
code block:
"
    // And likewise compare against the last ten entries

    Result = GetSystemPaletteEntries(hdc,PalHiStart,PalLoCount,SystemEntries);
    for (Count = 0;Count < Result;Count++) {

========================================
改正方法:

I had to change the code provided with platform SDK.

First the ctlutil.h from "operator=(LONG);" to "COARefTime& operator=(LONG);"
This solves one error and brings out 10 more.
Then wxdebug.cpp
from "static g_dwLastRefresh = 0;" to "static int g_dwLastRefresh = 0;"
Compile again and change in winutil.cpp
"for (Count = PalLoCount;INT(Count) < min(PalHiStart,iColours);Count++) {" to "for (int Count = PalLoCount;INT(Count) < min(PalHiStart,iColours);Count++) {"
 in outputq.cpp add the line
long iDone = 0; just before the "
 for (iDone = 0;
             iDone < nSamples || (m_nBatched != 0 && m_bSendAnyway);"
