链接器错误LNK2019在C ++中 [英] Linker error LNK2019 in C++

问题描述

我试图构建一个C ++程序，并继续得到这个错误，当我尝试定义一个新的功能和构建它。我解决了很少的他们，直到现在，但花了很多时间来详细了解错误。错误我现在得到如下：

I am trying to build a C++ program and keep on getting this error whenever I try defining a new function and building it. I resolved few of them till now, but spend a lot of time to understand the error in detail. Errors I am getting now are as per below:

通过各种论坛我理解，我需要添加一些库名称及其路径，但我不喜欢图书馆的事情。

Going through various forums I understood that I need to add some library name and its path, but I am bad at library thing. From where can I get its name and the path?

推荐答案

要使用库：
转到 Project /< projectname>属性/配置属性/ CC ++ /其他包含目录，并输入库的头文件所在的目录。

To use a library: go under Project/<projectname>Properties/Configuration Properties/CC++/Additional Include Directories and enter in the directory where the header files for the library are.

然后在配置属性/链接器/常规/附加库目录下输入lib目录的位置。

Then also under Configuration Properties/Linker/General/Additional Library Directories enter in the location of the lib directory.

然后在配置属性/链接器/输入/附加依赖项下将lib文件的名称lib目录。

Then under Configuration Properties/Linker/Input/Additional dependencies put the name(s) of the lib files in the lib directory.
