Linux环境下配置OpenCV及其运行错误解决方案

报错现象：

terminate called after throwing an instance of 'cv::Exception'
  what():  OpenCV(4.10.0) /home/user/Desktop/opencv/modules/highgui/src/window.cpp:1301: error: (-2:Unspecified error) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Cocoa support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function 'cvShowImage'

Aborted (core dumped)

　

解决方案：

sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen3-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev default-jdk ant libvtk5-qt4-dev

　　

可能会有几个软件包无法下载，将其删除即可。

 

下载完毕后需要重新编译安装OpenCV，即从头开始make编译。

 

运行报错：

Gtk-Message: 07:15:38.386: Failed to load module "canberra-gtk-module"

　　

解决方案：

sudo apt install libcanberra-gtk-module
