VScode配置c++版本opencv(亲测)

1. 下载安装包

(1)vscode官网下载

(2)opencv及其拓展库源码下载

本人下载的是455版本,注意opencv版本与opencv-contrib版本需一致

(3)MinGW下载

(4)cmake下载

2. vscode编译

(1)解压缩四个安装包,将mingw64的bin添加到环境变量

 win+R打开cmd,输入gcc --version,如图所示表明安装成功

 (2)vscode编译

  • 运行c-make包bin目录下cmake-gui.exe

  •  选择要编译的源码路径,再选择编译存放的路径(自己新建一个文件夹)。
  •  点击configure,选择MinGW MakefilesSpecify native compilers
  • 点击Next,编译器选择,C选择MinGW-w64的bin目录下gcc.exe,C++则选择g++.exe
  •  点击Finish,然后自动开始配置。
  • 搜索extra,添加扩展路径(opencv_contrib-4.5.3\modules的路径)
  • 再点击configure,配置完成点击generate
  • 完成后,进入之前自己创建的编译结果存放的文件夹,按住shift再按鼠标右键,选择在此进入powershell窗口。
  • 输入MinGW32-make -j4 开始编译,大致要1个小时。
    (-j参数控制同时编译的cpu核数,这里选择4,根据自己电脑情况)。
  • 编译完成后,再输入MinGW32-make install进行安装。
  • 添加编译好的opencv环境变量
