yes it does, I double-checked it

no problem, now would you be so kind and give me an advice here if it is possible? I am stuck on this issue more than week :(

I know where are you heading. I found this in there:

OpenCV modules: To be built: core flann imgproc ml photo video imgcodecs shape videoio highgui objdetect superres ts features2d calib3d java stitching videostab Disabled: world Disabled by dependency: - Unavailable: cudaarithm cudabgsegm cudacodec cudafeatures2d cudafilters cudaimgproc cudalegacy cudaobjdetect cudaoptflow cudastereo cudawarping cudev python2 python3 viz

Both python modules are unavailable for some reason. Do you still need whole output?

I am trying to build the OpenCV from its sources and use its support for python. My predispositions:

  • downloaded latest opencv version 3.1.0
  • python 32bit version 3.5
  • numpy 32bit version 1.11.2
  • using CMake GUI for compilation
  • using Visual Studio Community 2015 for installation
  • using Visual Studio 2015 32bit compilator
  • following official tutorial: link text
  • Windows 10 64bit

After I run the build I can see that CMake cant find some source directories for building python3 module:

**Found PythonInterp: C:/Program Files (x86)/Python27/python2.exe (found suitable version "2.7.12", minimum required is "2.7") 
Found PythonLibs: C:/Program Files (x86)/Python27/libs/python27.lib (found suitable exact version "2.7.12") 
Found PythonInterp: C:/Program Files (x86)/Python35/python3.exe (found suitable version "3.5.1", minimum required is "3.4") 
Could NOT find PythonLibs (missing:  PYTHON_LIBRARIES PYTHON_INCLUDE_DIRS) (Required is exact version "3.5.1")**

However the missing directories for Python3 are not missing for Python2. Python3 has equal folder structure on my computer as Python2.

**However, the python3 module is still unavailable among opencv modules:

OpenCV modules:
    To be built:                 core flann imgproc ml photo video imgcodecs shape videoio highgui objdetect superres ts features2d calib3d java stitching videostab python2
    Disabled:                    world
    Disabled by dependency:      -
    Unavailable:                 cudaarithm cudabgsegm cudacodec cudafeatures2d cudafilters cudaimgproc cudalegacy cudaobjdetect cudaoptflow cudastereo cudawarping cudev python3 viz**

I can not find the reason why CMake is not able to find those paths. It finds right path for python3 executable, why not also include directory and python35.lib file?
