按照编译依赖

yum -y install epel-release
yum install gcc gcc-c++  
yum install cmake 
yum install python-devel numpy 
yum install ffmpeg-devel
yum install -y unzip zip

下载opencv 并解压

unzip opencv-3.4.7.zip 
cd  opencv-3.4.7
mkdir build
cd build/

编译

cmake -D WITH_TBB=ON -D WITH_EIGEN=ON ..    
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local .. 
make 
make install 

编译opencv的java版本

yum install ant
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -DBUILD_TESTS=OFF ..
make -j8
make install
