没有匹配的函数用于调用‘Php：：Extension：：add()

Question

我使用PHP-CPP来创建调用c++函数的PHP扩展。我已经解决了许多错误后，集成我的cpp到示例代码的cpp的PHP-CPP。但是我被以下错误所困扰，

 CapPicture.cpp: In function ‘void* get_module()’:
CapPicture.cpp:72:45: error: no matching function for call to ‘Php::Extension::add(const char [13])’
   extension.add<Demo_Capture>("Demo_Capture");

我的Cpp文件如下

        return HPR_ERROR;
    }


    NET_DVR_JPEGPARA strPicPara = {0};

    strPicPara.wPicSize = 0;
    int iRet;

        printf("pyd1---NET_DVR_CaptureJPEGPicture error, %d\n", NET_DVR_GetLastError());
        return HPR_ERROR;
    }

    //logout
    NET_DVR_Logout_V30(lUserID);
    NET_DVR_Cleanup();

    return HPR_OK;

}

extern "C" {
    PHPCPP_EXPORT void *get_module() {
        static Php::Extension extension("my_extension1", "1.0");  
        // extension.add("Demo_Capture",(int)Demo_Capture);
        extension.add<Demo_Capture>("Demo_Capture");
        return extension;
    }
}

请向我推荐一些解决上述错误的方法。

试试这个extension.add("Demo_Capture"，Demo_Capture)；
