CentOS8 OpenCV 설치

# Once the installation is completed, verify that OpenCV library exists by running:
pkg-config --modversion opencv

① Install the required and optional dependencies:

# CentOS repository에서 설치가 안됨
sudo dnf install opencv opencv-devel

# OpenCV source에서 설치가 안됨
sudo dnf install epel-release git gcc gcc-c++ cmake3 qt5-qtbase-devel \
    python3 python3-devel python3-pip cmake python3-devel python3-numpy \
    gtk2-devel libpng-devel jasper-devel openexr-devel libwebp-devel \
    libjpeg-turbo-devel libtiff-devel tbb-devel libv4l-devel \
    eigen3-devel freeglut-devel mesa-libGL mesa-libGL-devel \
    boost boost-thread boost-devel gstreamer1-plugins-base

# OpenCV source에서 몇개 문제되는것 빼고 아래 추가 설치
sudo dnf install epel-release git gcc gcc-c++ cmake3 qt5-qtbase-devel \
    python3 python3-devel python3-pip cmake python3-devel python3-numpy \
    gtk2-devel libpng-devel libwebp-devel \

sudo dnf install https://download-ib01.fedoraproject.org/pub/epel/7/aarch64/Packages/e/eigen3-devel-3.3.4-6.el7.noarch.rpm

Clone both OpenCV’s and OpenCV contrib repositories:

$ sudo mkdir -p ~/opencv_build && cd ~/opencv_build
$ sudo git clone https://github.com/opencv/opencv.git
$ sudo git clone https://github.com/opencv/opencv_contrib.git

Once the download is completed, create a temporary build directory, and switch to it:

$ cd ~/opencv_build/opencv && sudo mkdir build && cd build

Configure the OpenCV build with the following CMake command:

cmake3 -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_C_EXAMPLES=ON \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_GENERATE_PKGCONFIG=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_build/opencv_contrib/modules \
    -D BUILD_EXAMPLES=ON ..
