[Edit: It's Stretch, not Wheezy, sorry.]

I'm trying to build openCV on Raspberry Pi, following the instructions at https://www.pyimagesearch.com/2017/09/04/raspbian-stretch-install-opencv-3-python-on-your-raspberry-pi/ .

After installing all dependencies, I'm running:

cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_C_EXAMPLES=OFF \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \
    -D BUILD_EXAMPLES=ON ..

Which gives me the following output:

Can anyone help me understand why this is failing? I'm pretty new to OpenCV and CMake, so not sure what I'm doing wrong, or how to fix it...

    Possibly because you are trying to install on a 4+ year old doubly obsolete OS. You might have more "luck" with OpenCV 3.0, but I would ditch Wheezy – Milliways Feb 26 '18 at 2:17
  • @Milliways: May I suggest posting that as an answer? :P I would imagine that the package dependencies in a 4+ year old unsupported OS are hardly reliable at this point. – Jacobm001 Feb 26 '18 at 3:03
  • Dammit! That's a typo. It's actually Raspbian Stretch! Sorry about that. Fixed. – roach374 Feb 26 '18 at 6:29

You are requesting it to build contributed modules with the parameter

 -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules

but the configure script is unable to find it:

CMake Error at cmake/OpenCVModule.cmake:300 (message):
  No extra modules found in folder: /home/pi/opencv_contrib/modules

  Please provide path to 'opencv_contrib/modules' folder.
Call Stack (most recent call first):
  modules/CMakeLists.txt:7 (ocv_glob_modules)

Remove the parameter or add the contrib sources.

  • Yep! After taking a step back and thinking about it, the path was wrong. The correct CMAKE command was: cmake -D CMAKE_BUILD_TYPE=RELEASE \ -D CMAKE_INSTALL_PREFIX=/usr/local \ -D INSTALL_PYTHON_EXAMPLES=ON \ -D OPENCV_EXTRA_MODULES_PATH=~/opencv-3.4.0_contrib-3.3.0/modules \ -D BUILD_EXAMPLES=ON .. – roach374 Feb 27 '18 at 2:58
