如何将VC ++ DLL链接到MinGW Application? [英] How to link VC++ DLL to MinGW Application?

问题描述

大家好

我使用.h文件创建DLL.

Hi ALL

I Create the DLL Using .h file.

#pragma once
#ifdef USBINTERFACE_EXPORTS
#define USBINTERFACE_API __declspec(dllexport)
#else
#define USBINTERFACE_API __declspec(dllimport)
#endif

class USBINTERFACE_API CExportedClass
{
public:
	CExportedClass(void);
	void TestMessage();
public:
	~CExportedClass(void);
};

.cpp文件

.cpp file

#include "StdAfx.h"
#include "ExportedClass.h"

CExportedClass::CExportedClass(void)
{
}

CExportedClass::~CExportedClass(void)
{
}

void CExportedClass::TestMessage()
{
AfxMessageBox(L"Success");
}

我遵循链接步骤
http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs

命令:
reimp DLLTest.lib
pexports DLLTest.dll> DLLTest.def
dlltool -U -d DLLTest.def -l DLLTest.a
使用上述命令0kb会生成一个文件.
请让我知道如何解决此问题.

谢谢

With the use of above command 0kb .a file generated .
Please let me know how to solve this problem.

Thanks

推荐答案

是此 [^ ]帮助吗?

只是一个想法，但是也许您还需要在标头声明周围包含一些"extern C"包装，以便在导出函数时不进行任何名称修改. :)

Just a thought, but maybe you also need include some "extern C" wrappings around the header declaration so the functions are exported without any name mangling. :)

十年前，COM(Active X)用于在由不同编译器编写的库之间进行通信.如果MinGW支持，那么可能是进行研究的替代方法.

Ten years ago, COM (Active X) was used to communicate between library written by different compilers. If MinGW support it, then it might be an internative to investigate.
