STL将VS 6项目转换为VS2010时出错 [英] STL Error Converting VS 6 Project to VS2010

问题描述

我将Visual Studio 6项目转换为Visual Studio 2010.该项目大量使用STL。
转换后，编译器给出一个错误。代码和错误如下。

  #include< list> 
 
命名空间mySpace 
 {
 
模板< class T> 
 class MyList：public std :: list< T> 
 {
 public：
 typedef std :: list< T> :: allocator_type AllocatorType; 
} 
  

错误：
错误2错误C2146：语法错误： ;'before identifier'AllocatorType'c：\myProject\mylist.h 39 1

我可以点击'allocator_type'文本并点击F12，

如果我删除':: allocator_type'，错误消失。

任何想法会导致什么？

解决方案

应该是

  typedef typename std :: list< T> :: allocator_type AllocatorType; 
  

你必须告诉编译器allocator_type实际上是一个类型。

顺便说一句，继承STL容器不是一个伟大的做法，因为他们没有虚拟析构函数。

I'm converting a Visual Studio 6 project to Visual Studio 2010. The project uses STL heavily. After converting, the compiler gives an error. The code and error are as follows.

#include <list>

namespace mySpace
{

template <class T>
class MyList : public std::list<T>
{
    public:
        typedef std::list<T>::allocator_type AllocatorType;
    }

Error: Error 2 error C2146: syntax error : missing ';' before identifier 'AllocatorType' c:\myProject\mylist.h 39 1

I can click on the 'allocator_type' text and hit F12 and the IDE takes me to the 'allocator_type' definition in list.

If I remove '::allocator_type' the error goes away.

Any ideas what would cause this?

解决方案

It should be

typedef typename std::list<T>::allocator_type AllocatorType;

You have to tell the compiler allocator_type is actually a type.

By the way, inheriting from STL containers isn't a great practice as they don't have virtual destructors.
