有没有办法让不同编译器构建的c ++ dll相互兼容？这些类可以有工厂方法来创建和销毁,因此每个编译器都可以使用自己的new/delete(因为不同的运行时有自己的堆).

我尝试了以下代码,但它崩溃了第一个成员方法:

interface.h

#pragma once

class IRefCounted
{
public:
    virtual ~IRefCounted(){}
    virtual void AddRef()=0;
    virtual void Release()=0;
};
class IClass : public IRefCounted
{
public:
    virtual ~IClass(){}
    virtual void PrintSomething()=0;
};

test.cpp用VC9编译,test.exe

#include "interface.h"

#include <iostream>
#include <windows.h>

int main()
{
    HMODULE dll;
    IClass* (*method)(void);
    IClass *dllclass;

    std::cout << "Loading a.dll\n";
    dll = LoadLibraryW(L"a.dll");
    method = (IClass* (*)(void))GetProcAddress(dll, "CreateClass");
    dllclass = method();//works
    dllclass->PrintSomething();//crash: Access violation writing location 0x00000004
    dllclass->Release();
    FreeLibrary(dll);

    std::cout << "Done, press enter to exit." << …
