That is not currently the case, on OS X cv2.imshow() works with the latest build, but it fails on Linux and I am not able to test it in Windows.The main reason this PR used qt 4 is that it has worked for me previously on a similar recipe to build opencv 3.1.0.[Update] According to one of the users that tested it on Ubuntu 14.10, you’ll need to use WITH_FFMPEG=OFF. At the end of this post you’ll see a demonstration video of the installation and test. [Update] cd opencv-3.0.0-alpha mkdir build cd build cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON .. Script - Install Open CV 3.0.0 (24306 downloads) We will test to check if everything is working properly. The goal here is to prove that our Open CV installation was a success.

If you succeed, you should see a line like this after running I'm using conda features to manage opencv variants, so if you want the gtk2 version, you need to install a package tracking the gtk2 feature.I know it is not very intuitive, but that is as good as it gets with conda right now.
