Hi ALL

I Create the DLL Using .h file.

C++

#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 file

C++

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

CExportedClass::CExportedClass(void)
{
}

CExportedClass::~CExportedClass(void)
{
}

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

I follow the link step
http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs

Command:
reimp DLLTest.lib
pexports DLLTest.dll > DLLTest.def
dlltool -U -d DLLTest.def -l DLLTest.a
With the use of above command 0kb .a file generated .
Please let me know how to solve this problem.

Thanks

Solution 1

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. :)

extern "C"
{
class SLTUSBINTERFACE_API CExportedClass
{
public:
CExportedClass(void);
void TestMessage();
public:
~CExportedClass(void);
};
};
same it also not working ,same error

Extern C is mainly for C code (plain functions).

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.
