Hi, I'm on Ubuntu 14.04. I'm trying to install OpenCV 2.49 with Python 3.4 binding.

sudo cmake -D WITH_QT=ON -D WITH_OPENEXR=OFF -D WITH_XINE=ON -D WITH_OPENGL=ON -D WITH_TBB=ON -D BUILD_EXAMPLES=ON -D PYTHON_EXECUTABLE=/usr/bin/python3.4 ..

(I've disabled OpenEXR dependency since CMAKE wasn't working with it...) cmake is working apparently without error:

It seems your gtk version isn't update to gtk2.x + ... could you please check this by installing libgtk2.0-dev as suggested. However, it is possible the new ubuntu has a higher gtk version which you should remove first.

Thanks for your help. libgtk2.0-dev was installed but to no avail... But I solve the problem! I don't know why but the version of Python-OpenCV donwloaded was not the right one. Because I reinstall using the github version (using : sudo git clone https://github.com/Itseez/opencv.git ) and now everything is working! :)
