如何删除没有虚拟析构函数的多态类类型的对象 [英] How to delete an object of a polymorphic class type that has no virtual destructor

问题描述

当我尝试从第三方SDK编译一些代码时，我收到以下错误。

  *描述资源路径位置类型
删除具有非虚拟析构函数的多态类类型'Vendor_sys :: VendorCode'的对象可能导致未定义的行为[-Werror = delete-non-virtual-dtor] PnServer.cpp / PCounter行467 C / C ++问题* 
  

---

我不知道以满足这个条件，只有部分知识的供应商的SDK，其中大部分繁重的工作是在一个dll或库对象。

我的构建环境是Eclipse Juno gpp。

我在Google中搜索了错误消息，但没有发现此错误的任何实例。

因此，如果我不能修改供应商代码的黑盒部分，我的选项是什么？

这是在make过程中失败的代码：

  delete pData-> unit; 
  

解决方案

实际上，

现在，我将发送一个错误报告供应商。

I am getting the following error when I try to compile some code from a Third-party SDK.

*Description    Resource    Path    Location    Type
deleting object of polymorphic class type ‘Vendor_sys::VendorCode’ which has non-virtual destructor might cause undefined behaviour [-Werror=delete-non-virtual-dtor]   PnServer.cpp    /PCounter   line 467    C/C++ Problem*

I do not know if its possible to satisfy this condition with only partial knowledge of the Vendor's SDK, where most of the heavy lifting is done in a dll or library object.

My build environment is Eclipse Juno with gpp.

I searched in Google for the error message and did not find any instances of this error.

So, if I cannot modify the black box part of the vendor code, what are my options?

Here is the code that is failing during the make process:

delete pData->unit;

解决方案

Actually, I removed the -Werror switch from the compile and the program compiled.

Now, the messages are just warnings.

I will send a bug report to the vendor.
