_Unwind_Resume的多个定义 [英] Multiple Definitions of _Unwind_Resume

问题描述

一段时间以来，我一直在使用一小部分文件编写的文件，以便更轻松地与WinAPI交互.虽然，当我想重用它们，等待它们重新编译等操作时，不停地移动文件变得很痛苦.我最终决定只将它们放入DLL中，并完成它，但是我得到了每次尝试使用该库时，出现奇数链接错误.

For a while, I've been using a small collection of files I wrote making it easier to interface with WinAPI. Although, it's become a pain to keep moving the files around when I want to reuse them, waiting for them to recompile, etc. I finally decided to just throw them in a DLL, and be done with it, but I'm getting an odd link error every time I try to use the library.

该错误实际上与标题一样具体，几乎没有提供有关定义实际起源的信息(据我所知，考虑到该信息实际上无法从DLL中收集).有人可以请您解释到底是什么原因会导致此错误，以及提供一些可能的解决方案?

The error is really as specific as the title, providing little information about where the definition actually originates(considering, that kind of information can't really be collected from a DLL, as far as I'm aware). Could someone please explain exactly what would cause this error, as well as providing some possible fixes to the problem?

我正在使用MinGW(由SFML网站提供的相同版本4.4)以及Code :: Blocks(如果该信息有帮助的话).如果需要更多信息，我会尽力提供.

I'm using MinGW(the same version provided by the SFML site, 4.4) along with Code::Blocks, if that information helps any. If any more information is required, I'll do my best to provide it.

推荐答案

问题是名为_Unwind_Resume的符号(函数或变量)有多个定义.

The problem is that there are multiple definitions for a symbol (function or variable) named _Unwind_Resume.

DLL正在导出这样的名称.重建它，使其仅显示所需的符号.显然，它现在是在所有公共符号都被导出的情况下构建的.

The DLL is exporting such a name. Rebuild it so that it only exposes desired symbols. Apparently, it is now built with all public symbols being exported.
