关于visual studio 无法解析的问题

Question

我已经添加了所有的头文件以及dll，lib
但是仍然一直是报错

---

错误 LNK2019
无法解析的外部符号 "float __cdecl seeta::CalculateSimilarity(class VIPLFaceDetector &,class VIPLPointDetector &,class VIPLFaceRecognizer &,class cv::Mat const &,class cv::Mat const &)" (?CalculateSimilarity@seeta@@YAMAEAVVIPLFaceDetector@@AEAVVIPLPointDetector@@AEAVVIPLFaceRecognizer@@AEBVMat@cv@@3@Z)，该符号在函数 main 中被引用 ConsoleApplication1 G:文档Visual Studio 2015ProjectsConsoleApplication1ConsoleApplication1Main.obj 1

Answer 1

属性里 include lib路径选中需要外部引入的头文件和库文件
在Linker里面加入需要的lib库文件，重新编译。

Answer 2

生成 ——→ 重新生成解决方案

Answer 3

属性里面添加库，并且在头文件中添加目标的头文件
