I am using this script but getting following errors.

any idea what should I do
This fails for me with various errors - detailed here in the end of build report and CMakeError.log. This is a fresh clean Jessie with nothing else installed, running on an A+. Any idea what's causing it?
You might need to set -D INSTALL_C_EXAMPLES=OFF (rather than ON ) in the cmake command according to pyimagesearch.com
This seems to assume the script will be run in ~/
, which isn't always valid. I had to hand-fudge the cmake call a bit. Maybe document that assumption?
fresh pi3, fresh jessie ... no go...

Hi, the https://github.com/Itseez/
organization seems to be outdated, I get "301 Moved Permanently". You might want to use https://github.com/opencv/

Guys - If you got stuck here - follow these steps: https://imaginghub.com/projects/144-installing-opencv-3-on-raspberry-pi-3/documentation
Pay careful attention to this path: OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.1.0/modules
Make sure it points to where yours is.
Best,
Darshi
Nice script. It installed opencv for me without any error. Thanks
hi~
I use raspberry pi 1 B.
MAKEFLAGS="${MAKEFLAGS:--j 4}"
Pi model 1 B can't use option '--j 4'.
How can I change this line?
