Why cv2.so missing after opencv installed?

How to install opencv(cv2) with python bindings in Linux – Ubuntu/Fedora

  1. Install gcc, g++/gcc-c++, cmake (apt-get or yum, in case of yum
    use gcc-c++)

    apt-get install gcc, g++, cmake

  2. Downlaod latest opencv from openCV’s website

  3. Untar it with

    tar -xvf opencv-*

  4. Inside the untarred folder make a new folder called release

    mkdir release
cd release

    (or any folder name) and run this command in it

    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_NEW_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..

    the .. will pull files from the parents folder and will get the system ready for
    installation on your platform.

  5. in the release folder run

    make

  6. After about 2-3 mins of make processing when its finished run

    sudo make install

  7. Export python path

    export PYTHONPATH=$PYTHONPATH:/usr/local/lib/python2.7/site-packages

That’s it, now go to python and try 

>>> import cv2

you should not get any error message.

Tested on python 2.7, should be virtually similar to python 3.x.
