我正在尝试使用以下架构在c ++中编写内容:

App - > Core(.so)< - 插件(.so)

对于linux,mac和windows.Core隐式链接到App,而插件显式链接到dlopen/LoadLibrary到App.我遇到的问题:

#include "raw_space.hpp"

#include <gamustard/gamustard.hpp>

using namespace Gamustard;
using namespace std;

namespace
{
  struct GAMUSTARD_PUBLIC_API RawSpacePlugin : public Plugin
  {
    RawSpacePlugin(void):identifier_("com.gamustard.engine.space.RawSpacePlugin")
    {
    }

    virtual string const& getIdentifier(void) const
    {
      return identifier_;
    }

    virtual SmartPtr<Object> createObject(std::string const& name) const
    {
      if(name == "RawSpace")
      {
        Object* obj = NEW_EX RawSpaceImp::RawSpace;
        Space* space = dynamic_cast<Space*>(obj);
        Log::instance().log(Log::LOG_DEBUG, "createObject: %x -> %x.", obj, space);
        return SmartPtr<Object>(obj);
      }
      return SmartPtr<Object>();
    }

  private: …

我在编译结束时遇到了这个奇怪的异常
