Ubuntu 18.04 installation of opencv2.4.13 encountered fatal error. Possible solutions
During the installation process, some fatal errors may occur. I haven’t found a method for a long time. I happened to see an article that the installation can be successful according to the following methods. Although the errors reported are not consistent, they can be used in this way.
Ubuntu installation opencv step pit
1、 Installation process
apt-get update
