删除某些标题后错误 LNK1120 已解决，但随后出现另一个错误(错误错误 C3861: 'cvPyrSegmentation': identifier not found ) [英] Error LNK1120 Solved After Removing Some Header, But Then There Is Another Error(Error error C3861: 'cvPyrSegmentation': identifier not found )

问题描述

实际上下面的代码是我试图执行的.当我尝试使用 Microsoft Visual Studio 2012 执行此操作时，出现错误.

Actually the coding below is what I tried to execute. When I tried to execute this using Microsoft Visual Studio 2012, there is an error.

错误错误 LNK2019:函数void __cdecl START_SEGMENT(int)"(?START_SEGMENT@@YAXH@Z) 中引用的未解析的外部符号 _cvPyrSegmentation

错误错误 LNK1120:1 个未解析的外部

但是我让我的朋友用他的笔记本电脑执行这段代码，它工作得很好.没有错误.但是他用的是Microsoft Visual Studio 2010，而不是我用的是Visual Studio 2012..我想知道为什么我执行这段代码时会出错，而我朋友执行时却没有错误.

But I asked my friend to execute this code using his laptop, it works just fine.No error. But he is using Microsoft Visual Studio 2010 instead of me using Visual Studio 2012..I wonder why there is an error when I execute this code but when my friend execute it, no error.

所以我删除了一些标题，编码看起来就像我从一开始问的那样(来自这个 ​​问题.带有 ""Error error C3861: 'cvPyrSegmentation': identifier not found ""..删除一些标题后，不再有错误 LNK1120.但是有"错误错误C3861:'cvPyrSegmentation':标识符未找到"...

So I removed some header and the coding looks like the one that I ask from the beginning( from this Question.The one with ""Error error C3861: 'cvPyrSegmentation': identifier not found "".. After I removed some header, there is no more Error LNK1120. But there is ""Error error C3861: 'cvPyrSegmentation': identifier not found""...

推荐答案

解决了编译问题后，您现在遇到了链接器问题.

Having fixed your compilation problem, you now have a linker problem.

您需要按照 OpenCV 文档中的说明了解如何将他们的库链接到您的二进制文件.

You need to follow the instructions in the OpenCV documentation to find out how to link their libraries to your binary.

您将从 -lcv 开始，并且可能需要添加一些额外的库.

You'll start with -lcv and potentially have to add some additional libraries.
