[ 22%] Built target pch_Generate_opencv_highgui
[ 22%] Built target opencv_highgui

You can either use plhn solution, or do git checkout on latest stable tag:

$git tag -l #list all tags
$git checkout 2.4.9 #thats the latest stable version

This will checkout the same version as in latest stable packages. But as a bonus, You can look into the sourcecode if some not clear exceptions appear.

Try a stable version

wget http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.9/opencv-2.4.9.zip/download

not cutting-edge version(from git)
