Question

我在构建项目时收到以下编译器错误：

XMLHelper.h（22）：错误C2678：二进制＆＃39;＆lt;＆lt;＆＃39; ：找不到哪个运算符采用了类型＆＃39; COSB :: AnyException＆＃39;的左手操作数。（或者没有可接受的转换）

XMLHelper.h代码：

 class XMLException : public COSB::Exception

{
public:
    XMLException(const MSXML2::IXMLDOMParseErrorPtr &verr, const char *prefix_description="XML error")
        : Exception(verr->errorCode)
    {
/*line 22  error line */
*this << prefix_description << " " << std::hex << long(verr->errorCode) << std::dec;
   ...}

XMLHelper.h不是我项目的直接组成部分。我检查了具有以下函数定义的exception.h：

class ExceptionBase : public std::exception
{ ...}

// Any exception including Win32 structured exceptions and COSB::Exception.
class AnyException: public ExceptionBase
{
public:

  // This insertion operator needed to be declared as a member function or the 
  //compiler gets confused as to which template function to apply.
     // Notice that stateful stream manipulators like width will probably not 
  //work

AnyException &operator<<( std::ostream& (_cdecl *f)(std::ostream&) )
{
    ExceptionBufferStream buf(FormatHolder());
    (*f)(buf);
    AppendToDescription(buf.c_str(),buf.LineSize());
    return  *this;
    }
   ..}

如何解决此错误？
