VS Code不能包含OpenCV标头

Question

在VS Code for C ++上使用OpenCV时遇到了一些问题。

我可以编译C代码，但是当我包含OpenCV库时，它总是显示以下错误消息：

  

严重错误：opencv2 / opencv.hpp：没有这样的文件或目录

我的VS Code版本是1.41.1（用户设置）。

我从此站点下载了OpenCV 3.4.1：
https://github.com/huihut/OpenCV-MinGW-Build

我计算机中的环境路径为：

OpenCV的路径是D：// opencv // build。

这是我在VS Code中使用OpenCV的配置：

Answer 1

“ D：\ opencv \ build \ include”是您的opencv安装路径吗？您可以cd到该目录并检查是否存在“ opencv2 / opencv.hpp”。关键是要找到“ opencv2 / opencv.hpp”在系统中的位置，然后将该路径放入c_cpp_properties.json“ includePath”。
