版本信息修改

输入命令

 sudo vim /usr/local/lib/pkgconfig/opencv.pc

将下列信息复制到文件中

prefix=/usr/local
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${exec_prefix}/lib

Name: opencv
Description: The opencv library
Version:4.8.0
Cflags: -I${includedir}/opencv4
Libs: -L${libdir} -lopencv_stitching -lopencv_objdetect -lopencv_calib3d -lopencv_features2d -lopencv_highgui -lopencv_videoio -lopencv_imgcodecs -lopencv_video -lopencv_photo -lopencv_ml -lopencv_imgproc -lopencv_flann -lopencv_core

　执行export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

　执行ldconfig 

验证安装

　1、执行pkg-config opencv --modversion将会打印版本号

　2、进入cd ~/opencv_install/opencv/samples/cpp/example_cmake

　3、输入 cmake . &&  make 

　4、./opencv_example可弹出黑窗

VScode 报错踩坑：

报错：无法打开 源 文件 "opencv2/videoio.hpp"

{
    "configurations": [
        {
            "name": "Linux",
            "includePath": [
                "${workspaceFolder}/**",
                "/usr/local/include/opencv4/" //此处为opencv4头文件等文件的默认安装目录
            ],
            "defines": [],
            "cStandard": "c17",
            "cppStandard": "gnu++14",
            "intelliSenseMode": "linux-gcc-x64"
        }
    ],
    "version": 4
}

编译报错

1、无法找到头文件

fatal error: opencv2/****

请将/usr/local/include/opencv4路径下的 opencv2/文件夹放置在 /usr/local/include/ 路径

2、编译源码错误

undefined reference to `cv::****

核对/usr/local/lib/pkgconfig/opencv.pc 文件中Libs: -L${libdir}行链接库数目与名称是否与 /usr/local/lib中opencv链接库是否一致

3、银河麒麟默认路径未发现头文件及lib库文件

银河麒麟库文件及头文件默认保存在 /user/lib/x86_64-linux-gnu/和 /user/include/x86_64-linux-gnu/中，需要修改sudo vim /usr/local/lib/pkgconfig/opencv.pc文件路径
