Gtk-Message: 09:56:19.551: Failed to load module "canberra-gtk-module"

解决办法

cmake
make
....
[100%] Built target opencv_example
admin@ub:~/opencv/samples/cpp/example_cmake/build$ ./opencv_example

^C

成功！
这是黎明前最后个问题，故放在前面。

以下是查看 history 复盘 Ubuntu 20.04 install OpenCV 4.7.0后改为4.6.0。
个人总结，非保姆级教程，最新最详细看向日葵骑士Faraday原创的Ubuntu18.04安装Opencv4.5(最新最详细)。虽然我是中途参考，但获益良多。

自动与手动 an 装

标题很吸引，但自动与手动an装均未成功，事后发现一处错误，原帖（看这篇就够了——opencv与libopencv与cv_bridge的安装与使用）里验证opencv是否安装

pkg-config --modversion opencv

在我电脑上验证

admin@ub:~/opencv$ pkg-config --modversion opencv
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
admin@ub:~/opencv$ pkg-config --modversion opencv4
4.6.0

这部分是失败的循环。

在linux中， ldd是list, dynamic, dependencies的缩写， 列出动态库依赖关系。

  475  ./camera
  476  cat ../README.md 
  477  ldd camera
  478  sudo aptitude install opencv
  479  locate libopencv_highgui
  480  sudo find / -name "libopencv_highgui"
  481  sudo aptitude install opencv
  482  sudo aptitude install libopencv-highgui-dev
  483  ./camera
  484  ldd camera
  485  sudo find / -name "libopencv_highgui"
  486  su
  487  sudo aptitude install python3
  488  python3
  489  ./camera
  490  ldd camera
  498  ./camera
  499  sudo aptitude install libopencv-dev
  505  sudo aptitude install ros-noetic-cv-bridge

  511  pkg-config --modversion opencv
  512  sudo apt-get install libopencv-highgui-dev
  523  ldd camera
  524  ldd gtk2.0-dev

运行./camera 命令时，报错缺少libopencv_highgui.so.3.2，ldd 查看依赖。

以上代码选自问题解决：运行./darknet命令时，报错缺少libopencv_highgui.so.3.2包，不想折腾或首次an装看上文保姆教程。

官网教程

获取源码

OpenCV官网地址OpenCVReleases
OpenCVTutorials，注意Opencv的版本号。

Cmake 手动编译 Opencv

复习常用解压缩命令

tar -zcvf
tar -zxvf
gzip 
gzip -d 
zip
unzip

这部分是参考官网Quick start
Build core modules，Installation in Linux 。

# Install minimal prerequisites (Ubuntu 18.04 as reference)
sudo apt update && sudo apt install -y cmake g++ wget unzip
# Download and unpack sources
wget -O opencv.zip https://github.com/opencv/opencv/archive/4.x.zip
unzip opencv.zip
# Create build directory
mkdir -p build && cd build
# Configure
cmake  ../opencv-4.x
# Build
cmake --build .

这部分官网教程不适合排查问题，可能一处错误后面无法进行。
