问题描述
大家好，
我正在开发一个具有客户端和服务器的临时应用程序。客户端使用C＃编写为带有表单等的普通Windows应用程序。服务器将接收TCP / IP套接字消息以进行处理和响应。
我希望SERVER成为一个C ++公共代码，可以链接到Windows和Linux，只需更少的更改尽可能地，我可以在Windows和Linux机器上运行服务器。
所有常见的类和方法（由CLIENT和SERVER使用）都存储在一个可以链接到CLIENT和SERVER的COMMONLIBRARY。
我将它全部放入Visual Studio 2010解决方案中：
客户端 - 客户端C＃代码。
服务器 - 服务器C ++代码。
我还创建了一个公共库作为DLL项目 - COMMONLIBRARY
我将库创建为将生成DLL的C ++ CLASS LIBRARY。所以代码看起来像：
Hi all,
I´m developing a from scratch application that will have a client and a server. The client is being written with C# as a normal Windows application with forms and so forth. The server will receive TCP/IP socket messages for processing and respond.
I want the SERVER to be a C++ common code to be linked into Windows and Linux with less changes as possible, so that I can run the server on both Windows and Linux machines.
All the common classes and methods (used by CLIENT and SERVER) are being stored on a COMMONLIBRARY that can be linked to both CLIENT and SERVER.
I put it all into a Visual Studio 2010 solution:
CLIENT - The client C# code.
SERVER - The server C++ code.
I had also created a common library as a DLL project - COMMONLIBRARY
I created the library as a C++ CLASS LIBRARY that will generate a DLL. So the code look likes:
#pragma once
using namespace System;
namespace COMMONLIBRARY {
#include <string>
public ref class clsLog
{
private:
//
// Properties
//
string m_strCurLogUser;
public:
// Methods
int clsLog::Init (std::string FileName)
};
}
#include <string>
class Foo
{
string m_strMessage;
}
字符串类型无法识别。当我将std :: string添加为：
The string type is not being recognized. When I add std::string as:
std::string m_strCurLogUser;
然后我收到C4368错误 - 不支持混合类型。
如果我关闭公共语言运行时以使用标准C ++语言（att项目 - >属性），代码没有编译，有几个错误和内部库。
有人可以给出一些暗示吗？
在该环境中定义和使用字符串的最佳选择是什么？
如何让SERVER尽可能多地通用并将其绑定到Visual Studio环境？
任何帮助赞。

Then I´m getting C4368 error - mixed types are not supported.
If I turn off "Common Language Runtime" to use the standard C++ language (att Project->properties), the code doesn´t compile with several errors and the internal libraries.
Can someone gimme a hint of what´s going on ?
What´s the best option to define and use strings on that environment ?
How can I get the SERVER as much generic as possible and tying it to the Visual Studio environment ?
Any help appreciated.

推荐答案
namespace COMMONLIBRARY {
#include <string>
...
</string>
这是一个非常糟糕的主意，因为它试图将< string> 标题中的所有内容定义为 COMMONLIBRARY 名称空间。这可能看起来像一个简洁的想法，但相信我，它将无法奏效。在Windows环境中包含< string> 会带来数十个标题，包括 Windows.h 本身有效地重新定义了所有内容。命名空间内的Win32 API。
我会尝试在 COMMONLIBRARY 之外移动 #include 命名空间。
That''s a really bad idea as it tries to define everything in and included by the <string> header as being in the COMMONLIBRARY namespace. That might seem like a neat idea but believe me it will not work. Including <string> in a Windows environment brings in dozens of headers including Windows.h itself effectively redefining everything from the Win32 API inside the namespace.
I would try moving the #include outside the COMMONLIBRARY namespace.
#include <string>
namespace COMMONLIBRARY {
...
</string>
