[环境配置][原创]ubuntu上opencv源码编译流程

测试环境：

ubuntu16.04和ubuntu18.04，ubutnu20.04(gcc-7测试通过)

编译流程：

第一步安装依赖：

sudo apt-get -y install ffmpeg x264 libx264-dev libopencv-dev build-essential checkinstall cmake git pkg-config yasm sudo apt-get -y install libtiff5-dev libjpeg-dev libavcodec-dev libavformat-dev libswscale-dev sudo apt-get -y install libtbb-dev libtbb2 libqt4-dev libgtk2.0-dev sudo apt-get -y install libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev sudo apt-get -y install v4l-utils  libgtk2.0-dev libatlas-base-dev gfortran

第二步源码编译：

cd opencv-3.4.4 mkdir build cd build cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. make (自己电脑是8核心的make -j8) sudo make install pkg-config --modversion opencv  #查看 opencv 版本验证是否安装成功
