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.

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.

@koruitch

i have problem. not objet makefile installing opencv.

@hexagon-robotics

Thank you!,

I could install without any problems.

@andreasringdal

If you got a fresh rasbian image you might have to do a
sudo apt-get install cmake

@porktech

This is with python 3.x.x bindings?

@danbornman

Does this include FFMEG? I don't see it in the dependencies section.

@timbuktu031

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):
modules/CMakeLists.txt:7 (ocv_glob_modules)"
in the End I am getting following message

"-- Configuring incomplete, errors occurred!

any idea what should I do

@geotheory

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?

@luisomoreau

You might need to set -D INSTALL_C_EXAMPLES=OFF (rather than ON ) in the cmake command according to pyimagesearch.com

@fake-name

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?

@theBerryman

fresh pi3, fresh jessie ... no go...
