這不是系統問題，主要是路徑的問題，“CL.exe”是VC使用真正的編譯器（編譯程式），其路徑在“VC根目錄\VC98\Bin”下面

下面給你說說路徑的設定

如果你是按照初始路徑安裝vc6.0的，路徑應為：

executatblefiles:

C:\ProgramFiles\MicrosoftVisualStudio\Common\MSDev98\Bin

C:\ProgramFiles\MicrosoftVisualStudio\VC98\BIN

C:\ProgramFiles\MicrosoftVisualStudio\Common\TOOLS

C:\ProgramFiles\MicrosoftVisualStudio\Common\TOOLS\WINNT

includefiles:

C:\ProgramFiles\MicrosoftVisualStudio\VC98\INCLUDE

C:\ProgramFiles\MicrosoftVisualStudio\VC98\MFC\INCLUDE

C:\ProgramFiles\MicrosoftVisualStudio\VC98\ATL\INCLUDE

libraryfiles:

C:\ProgramFiles\MicrosoftVisualStudio\VC98\LIB

C:\ProgramFiles\MicrosoftVisualStudio\VC98\MFC\LIB

sourcefiles:

C:\ProgramFiles\MicrosoftVisualStudio\VC98\MFC\SRC

C:\ProgramFiles\MicrosoftVisualStudio\VC98\MFC\INCLUDE

C:\ProgramFiles\MicrosoftVisualStudio\VC98\ATL\INCLUDE

C:\ProgramFiles\MicrosoftVisualStudio\VC98\CRT\SRC

如果不是初始路徑的話，就按照你安裝的VC98路徑來...
