一、准备工作：
CentOS-7-x86_64-DVD-1810（7.6版本）
ffmpeg-4.2.4.tar.xz 源码
opencv-4.5.5.zip 源码
以上三个库自己可以下载。
二、更换源
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
三、安装依赖
yum -y install epel-release rpm --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro rpm -Uvh http://li.nux.ro/download/nux/dextop/el6/x86_64/nux-dextop-release-0-2.el6.nux.noarch.rpm yum install -y ant autoconf automake freetype-devel libtool yum install -y gcc gcc-c++ cmake3 git pkgconfig gtk2 gtk2-devel gtk2-devel-docs python python-pip python-devel yum install -y numpy gimp-devel gimp-devel-tools libtool-ltdl libtool-ltdl-devel* python-numpy libavc1394-devel yum install -y gimp-help-browser libjpeg-devel libtiff-devel libpng-devel gstreamer-devel gstreamer-plugins-base-devel yum install -y libraw1394-devel libdc1394-devel jasper-devel jasper-utils libv4l libv4l-devel yum install -y zlib-devel unzip swig libtool nasm libgnomeui-devel gnome-devel gnome-devel-docs kernel-devel gcc-gfortran
四、编译ffmpeg
cd ffmpeg-4.2.4 ./configure --enable-shared --enable-pic --prefix=/soft/ffmpeg make -j8 make install vim /etc/ld.so.conf.d/ffmpeg.conf include ld.so.conf.d/*.conf /soft/ffmpeg/lib/ ldconfig vim /etc/profile export PATH=$PATH:/soft/ffmpeg/bin source /etc/profile vim /etc/bashrc export LD_LIBRARY_PATH=/soft/ffmpeg/lib export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/soft/ffmpeg/lib/pkgconfig export PKG_CONFIG_LIBDIR=$PKG_CONFIG_LIBDIR:/soft/ffmpeg/lib source /etc/bashrc 使opencv能找到ffmpeg cp /soft/ffmpeg/lib/pkgconfig/* /usr/share/pkgconfig/
五、编译opencv
cd opencv-4.5.5 mkdir build cd build cmake3 -DCMAKE_BUILD_TYPE=Release -DWITH_1394=ON -DOPENCV_GENERATE_PKGCONFIG=ON -DCMAKE_INSTALL_PREFIX=/soft/opencv455 -DWITH_FFMPEG=ON -DBUILD_TESTS=OFF -DBUILD_opencv_world=ON .. make -j8 make install vim /etc/profile.d/pkgconfig.sh 在pkgconfig.sh文件中写入（可能是空文件）： export PKG_CONFIG_PATH=/soft/opencv455/lib64/pkgconfig:$PKG_CONFIG_PATH 最后： source /etc/profile source /etc/profile.d/pkgconfig.sh vim /etc/ld.so.conf.d/opencv4.conf 在opencv4.conf文件中写入（可能是空文件）： /soft/opencv455/lib64 ldconfig pkg-config --modversion opencv4
六、设置共享
su root vmhgfs-fuse .host:/CentosShare /mnt/hgfs -o allow_other
七、编译自己的库
修改HXVDDLL.h #define ON_WINDOWS 0 cd HXVDDLL make cp libHXVDDLL.so ../lib cd ../AlgTest make cp testAlg ../lib cd ../lib ./testAlg 如果出现找不到库的情况，需要添加环境变量 gedit /etc/ld.so.conf.d/HXVD.conf /home/long/zl/HXVD/lib ldconfig /sbin/ldconfig.real: /home/long/zl/HXVD/lib/libopencv_world.so.4.5 is not a symbolic link cd /home/long/zl/HXVD/lib sudo ln -sf libopencv_world.so.4.5.5 libopencv_world.so.4.5 sudo ln -sf libopencv_world.so.4.5 libopencv_world.so
