Do I need Python to build OpenCV from source using cmake?

opencv-users mailing list
I'm getting this message in cmake-gui after I click configure:


 CUDA detected: 7.5
 CUDA NVCC target flags: -gencode;arch=compute_20,code=sm_20;-gencode;arch=compute_20,code=sm_21;-gencode;arch=compute_30,code=sm_30;-gencode;arch=compute_35,code=sm_35;-gencode;arch=compute_30,code=compute_30
 To enable PlantUML support, set PLANTUML_JAR environment variable or pass -DPLANTUML_JAR=<filepath> option to cmake

 Could NOT find PythonInterp: Found unsuitable version "2.7.11", but required is at least "3.2" (found C:/Python27/python.exe)
 

I don't plan to write any Python in OpenCV. Just C/C++. OpenCV is written in C/C++, right? Can I build it without Python? I know how to uncheck modules in cmake when I don't need them, but don't see the Python module I could unclick.

Thanks.

You should only have to unclick the Python entries.  With OpenCV 3.1 there
are 8 entries for Python 2 and 8 more for Python 3.  Cmake-gui has a search
text box to help you find it for other versions of OpenCV.
