c++ - LNK2022 使用/clr 时出错

Question

使用 /clr 编译选项时，我在 VS2008 中链接 C++ 项目时遇到问题。我收到以下构建错误:

Class1.obj : error LNK2022: metadata operation failed (8013118D) : Inconsistent layout information in duplicated types (_PROPSHEETPAGEA): (0x0200046f).
Class1.obj : error LNK2022: metadata operation failed (8013118D) : Inconsistent layout information in duplicated types (_PROPSHEETPAGEW): (0x02000473).

LINK : fatal error LNK1255: link failed because of metadata errors

我不知道 PROPSHEETPAGEA 和 PROPSHEETPAGEW 指的是什么。我在网上查看了 Microsoft 对错误的描述，但对它的含义一头雾水。 http://support.microsoft.com/kb/324088

To resolve this problem, add unique identifiers when you use Managed Extensions for C++ so that you avoid using anonymous structures as global variables.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This bug was corrected in Microsoft Visual C++ .NET (2003).

任何想法将不胜感激。

在对 Class1.obj 执行 ildasm 之后，我提取了两条消息:

我不确定这一切意味着什么，但看起来第二个条目与第一个条目相同，除了向后定义的属性。

Answer 1

我今天在我的一个项目中遇到了完全相同的问题。我通过重新排列我的头文件来解决它。问题是我将头文件移动到 cpp 文件的顶部，在包含 windows.h 的文件之前。所以，一旦我恢复了包含顺序，并将 windows.h 放回 cpp 文件的顶部，它就修复了所有问题。

非常奇怪的修复，但对我有用。
