ubuntu16.04安装opencv3.4

参考blog: https://blog.csdn.net/u013066730/article/details/79411767
直接进行,完全没问题
sudo apt-get install build-essential libgtk2.0-dev libavcodec-dev libavformat-dev libjpeg.dev libtiff4.dev libswscale-dev libjasper-dev

mkdir my_build_dir
cd my_build_dir

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local …

sudo make

sudo make install

sudo gedit /etc/ld.so.conf.d/opencv.conf

文件末尾添加 /usr/local/lib

sudo ldconfig

配置 bash
sudo gedit /etc/bash.bashrc
末尾添加
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
export PKG_CONFIG_PATH

sudo updatedb

这样就OK了
