Raspberry Pi OpenCV 3.2 설치

라즈베리파이에서 OpenCV 3.2 설치하기

다른 운영체제에서 설치하듯이 설치하는 방법은 똑같지만

라즈베리파이에서 하나 추가해야 할 게 있다면 swap 메모리 설정

swap 메모리를 늘려주지 않고 설치하면 make에서 진행이 안된다.

 

$  sudo nano /etc/dphys-swapfile
# CONF_SWAPSIZE=100 을 CONF_SWAPSIZE=1024 로 변경해주자.
$  sudo /etc/init.d/dphys-swapfile stop
$ sudo /etc/init.d/dphys-swapfile start

sudo apt-get install g++
