shared_ptr包括托管代码时未定义 [英] shared_ptr not defined when including from managed code

问题描述

我试图在非托管C ++静态库中编写一个托管包装器（C ++ / CLI），并且有两个问题：

1. 非托管库在其头中使用 std :: shared_ptr 。 < memory> ，并且标题作为非托管项目的一部分编译。但是，当我在受管项目中包含此标题时，我收到此错误：

   
   
   

   错误C2039：'shared_ptr'：不是'std' > c> c> c $>

/ code>从C ++ / CLI？我似乎找不到任何正确的语法示例，并且C＃-style语法不编译。

代码for＃1：

  // 1> Dummy.h（10）：error C2039：'shared_ptr'：不是成员'std'
 #pragma once 
 
 #pragma managed（push，off）
 
 #include< memory> 
 
 class Foo {}; 
 typedef std :: shared_ptr< Foo> FooPtr; 
 
 #pragma managed（pop）
 
 
使用命名空间System; 
 
命名空间Dummy {
 
 public ref class Class1 
 {
 public：
 Class1（FooPtr）; 
}; 
} 
  

解决方案

：编辑$（IncludePath）"宏"在Visual Studio 2010

Visual Studio 2010包括Visual Studio 2008中的标头，它们没有 shared_ptr 。

确切的分辨率描述此处。 常规选项卡上的平台工具集默认为 vs90 。将此更改为 vs100 可解决此问题。

I'm trying to write a managed wrapper (C++/CLI) around an unmanaged C++ static library and am having two problems:

1. The unmanaged library uses std::shared_ptr in its headers. <memory> is included, and the header compiles as part of an unmanaged project. When I include this header in the managed project, however, I receive this error:

   error C2039: 'shared_ptr' : is not a member of 'std'

2. How do I access the Values collection of a SortedDictionary<K, V> from C++/CLI? I cannot seem to find any examples of the proper syntax, and the C#-style syntax does not compile.

Code for #1:

// 1>Dummy.h(10): error C2039: 'shared_ptr' : is not a member of 'std'
#pragma once

#pragma managed(push, off)

#include <memory>

class Foo {};
typedef std::shared_ptr<Foo> FooPtr;

#pragma managed(pop)


using namespace System;

namespace Dummy {

    public ref class Class1
    {
    public:
        Class1(FooPtr);
    };
}

解决方案

I have found the answer here: Edit $(IncludePath) "macro" in Visual Studio 2010

Visual Studio 2010 is including the headers from Visual Studio 2008, which do not have shared_ptr.

The exact resolution is described here. The Platform Toolset on the General tab defaulted to vs90. Changing this to vs100 resolved the issue.
