Why does cv2.waitkey function cause error using conda on ubuntu

I've been using cv2 with anaconda successfully until I added:

cv2.waitKey(0)

receiving this error:

cv2.error: -------src-dir-------/opencv-2.4.10/modules/highgui/src/window.cpp:562: error: (-2) The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script in function cvWaitKey

I'm using conda 3.14.0 on Ubuntu 14.04.2 LTS and the packages in the error advice are installed

The order of installation matters. The error message says you must have libgtk2.0-dev and pkg-config installed before installing opencv2. - unutbu
I had opencv installed before anaconda. then i installed it again through anaconda. what should i do? - Rubber Duck
Did you uninstall opencv, install libgtk2.0-dev and pkg-config and then install opencv again? - unutbu
I did but im not sure what the anaconda installation did to that. it might be local - Rubber Duck
Is this problem fixed? I'm having the same problem here too. - Ébe Isaac

In summary, you can try:

For opencv2.X

conda install -c https://conda.anaconda.org/menpo opencv
