sudo ln -s /usr/lib/arm-linux-gnueabihf/libhdf5_serial_hl.so /usr/lib/arm-linux-gnueabihf/libhdf5_hl.so


## お手軽 for Python only
# sudo pip3 --default-timeout=1000 install opencv-python


### Swapの増加 ###
swapon
sudo sed -i -e 's/SWAPSIZE=.*/SWAPSIZE=2048/g' /etc/dphys-swapfile
sudo systemctl restart dphys-swapfile.service
swapon


### OpenCVコードの取得 ###
cd ~/
mkdir work
cd work

cvVersion="4.1.0"

git clone https://github.com/opencv/opencv.git
cd opencv
git checkout $cvVersion
cd ..

### opencv_contribもビルドしたい場合 ###
# git clone https://github.com/opencv/opencv_contrib.git
# cd opencv_contrib
# git checkout $cvVersion
# cd ..
# CMakeに↓を追加
#    -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \

### Openビルド設定 ###
cd ~/work/opencv
mkdir build
cd build
