Hey @tuchs, yeah, bit buggy isn't it! I've just uploaded my most recent revision which seems to now build. Let me know if you've got any further problems.
i have problem. not objet makefile installing opencv.
Thank you!,
I could install without any problems.

If you got a fresh rasbian image you might have to do a
sudo apt-get install cmake
This is with python 3.x.x bindings?
Does this include FFMEG? I don't see it in the dependencies section.
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?
I am using this script but getting following errors.
"-- VTK is not found. Please set -DVTK_DIR in CMake to VTK build directory, or to VTK install subdirectory with VTKConfig.cmake file
CMake Error at cmake/OpenCVModule.cmake:295 (message):

Please provide path to 'opencv_contrib/modules' folder.
Call Stack (most recent call first):

in the End I am getting following message

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Hi, the https://github.com/Itseez/ organization seems to be outdated, I get "301 Moved Permanently".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/ instead. hth Frank

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
Typo in line 66? When I tried to install opencv manually and enable the c examples cmake failed in samples/gpu/CMakeLists.txt, looks like a bug in there.
