Install OpenCV 4 on CentOS 7 (C++ and Python)

 https://learnopencv.com/install-opencv-4-on-centos-7/

加入动态库文件所在的目录：执行vi /etc/ld.so.conf，在"include ld.so.conf.d/*.conf"下方增加

include ld.so.conf.d/*.conf
/usr/local/lib64
/usr/local/lib

 echo "/usr/local/lib64" >> /etc/ld.so.conf
 echo "/usr/local/lib" >> /etc/ld.so.conf

sudo ln -s /usr/local/lib64/pkgconfig/opencv4.pc /usr/share/pkgconfig/
sudo ldconfig

运行：/sbin/ldconfig –v更新一下配置即可。

临时解决方案

export LD_LIBRARY_PATH=/usr/local/lib64:$LD_LIBRARY_PATH 

sudo dnf install gtk3-devel -y
sudo dnf install libcanberra-gtk3 -y

--   GUI:                           GTK3
--     GTK+:                        YES (ver 3.22.30)

 或者GTK2

sudo dnf install gtk2-devel -y
sudo dnf install libcanberra-gtk2 -y
