使用的PHP版本是7.3 ；opencv 版本是 4+
1、安装php-opencv 首先需要先安装opencv
需要epel来安装部分的插件
yum -y install epel-release
需要安装一系列的依赖 支持opencv --会需要很长的时间
sudo yum -y ffmpeg ffmpeg-devel --downloadonly --downloaddir=. sudo yum -y install git gcc gcc-c++ cmake3 cmake-gui sudo yum -y install qt5-qtbase-devel sudo yum install -y python34 python34-devel python34-pip sudo yum install -y python python-devel python-pip sudo yum -y install python-devel numpy python34-numpy sudo yum -y install gtk2-devel sudo yum -y install vlc sudo yum install -y libpng-devel sudo yum install -y jasper-devel sudo yum install -y openexr-devel sudo yum install -y libwebp-devel sudo yum -y install libjpeg-turbo-devel sudo yum install -y freeglut-devel mesa-libGL mesa-libGL-devel sudo yum -y install libtiff-devel sudo yum -y install libdc1394-devel sudo yum -y install tbb-devel eigen3-devel sudo yum -y install boost boost-thread boost-devel sudo yum -y install libv4l-devel sudo yum -y install gstreamer-plugins-base-devel sudo yum -y install autoconf automake mercurial pkgconfig zlib-devel libtool freetype-devel make sudo yum install -y hdf5-devel sudo yum install -y liblas-devel atlas-devel sudo yum install -y gcc-gfortran sudo yum install -y libevent-devel lua-devel openssl-devel flex mysql-devel sudo yum install -y xz gettext-devel sudo yum install -y tcl sudo yum install -y openblas-devel sudo yum install -y tesseract-devel tesseract-osd sudo yum install -y java-1.7.0-openjdk-devel sudo yum install -y pylint sudo yum install -y python-flake8 sudo yum install -y vtk-devel vtk-python vtk-qt vtk sudo yum install -y ccache sudo yum install -y gflags gflags-devel sudo yum install -y glog glog-devel sudo yum install -y libpng libpng-devel sudo yum install -y libXaw-devel freeimage freeimage-devel zziplib-devel cppunit-devel libXt-devel libX11-devel sudo yum install -y re2c libgnomeui-devel sudo yum install -y gcc gcc-c++ gtk2-devel gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devel libpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-devel jasper-devel jasper-utils swig python libtool nasm sudo yum install -y gcc g++ cmake git python-devel numpy gtk2 libdc1394 libv4l gstreamer* nasm libtool swig jasper libdc1394-devel jasper-devel jasper-utils libraw1394-devel libgphoto2 tesseract libavc1394-devel gstreamer-devel libpng-devel libjpeg-devel libtiff-devel zlib-devel gimp gimp-devel gtk+-devel yasm libpciaccess libva-freeworld libva-intel-driver phonon-backend-gstreamer
2、拉取opencv 的源码
git clone https://github.com/opencv/opencv_contrib.git git clone https://github.com/opencv/opencv.git
最好的放在同一目录下 后边会使用到
3、opencv 的编译
cd opencv mkdir build cmake3 -D CMAKE_BUILD_TYPE=RELEASE .. cmake3 -D CMAKE_INSTALL_PREFIX=/usr/local .. cmake3 -D INSTALL_C_EXAMPLES=ON .. cmake3 -D INSTALL_PYTHON_EXAMPLES=ON .. cmake3 -D WITH_TBB=ON -D WITH_EIGEN=ON .. cmake3 -D WITH_V4L=ON .. cmake3 -D OPENCV_SKIP_PYTHON_LOADER=ON .. cmake3 -D OPENCV_GENERATE_PKGConFIG=ON .. cmake3 -D WITH_QT=ON .. cmake3 -D WITH_OPENGL=ON .. cmake3 -D PYTHON_DEFAULT_EXECUTABLE=/usr/bin/python3 .. cmake3 -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..
注意： 最后一条的路径 之前放在同一目录下可以不用更改
cmake3 -D ENABLE_CXX11=ON .. make && make install
检测是否编译成功 可以查看 /usr/local/lib64/pkgconfig 这个目录下是否有 opencv4.cp 这个文件
4、修改环境变量 永久生效
vi /etc/profile export PKG_CONFIG_PATH=/usr/local/lib64/pkgconfig # 在最后一行加上 source /etc/profile
5、查看是否成功
pkg-config --libs opencv
6、安装PHP-opencv
1) 下载php-opencv 源码
git clone https://github.com/hihozhou/php-opencv.git
2）
cd php-opencv phpize ./configure --with-php-config=/usr/local/php/bin/php-config --enable-debug make CXXFLAGS='-std=c++11' make install
3) 在php.ini 中加入
extension=opencv.so
4）保存退出 重启php 即可
5）可以php-m 查看是否成功
出现的问题： 1、一定要注意你安装的版本
2、编译会很慢 ，opencv 编译会失败，可以先删除那个模块试试
