如何解决“dllmain.obj：错误LNK2019：未解析的外部符号”public"制作DLL项目时出错？ [英] How to solve “dllmain.obj : error LNK2019: unresolved external symbol ”public" error while making a DLL project?

问题描述

大家好吧

我想为软件制作一个插件。为了制作插件，我应该制作一个dll文件（带有dll扩展名的文件），但是我遇到了很多关于制作它的挑战。我的系统是Windows 7，我使用Microsoft Visual Studio 2010作为IDE。我做了一个dll项目并制作了两个源文件和一个头文件，然后我构建了解决方案，但是我遇到了以下错误，（在构建解决方案之前，我添加了软件的include和lib目录的路径）。如果有人可以帮我解决这个问题，我将不胜感激。

Hi every body
I want to make a plugin for a software. In order to make the plugin, I should make a dll file (a file with dll extension) but I have faced many challenges about making it . my system is windows 7 and I'm using Microsoft visual studio 2010 as an IDE. I made a dll project and made two source files, and one header file and then I build the solution but I encountered the following errors, (before building the solution I added the path of include and lib directories of the software). I would appreciate if someone could help me with this problem.
