Installation of required packages by root (first line is essential for everything, others depend on whether you want the video and GUI interfaces respectively):
yum install cmake gcc-c++ yum install ffmpeg ffmpeg-devel yum install gtk2-devel
Download the latest code :
git clone git://code.opencv.org/opencv.git
Build the code in an out-of-source directory (chosen to be 'release' here) :
cd opencv mkdir release cd release cmake -D CMAKE_BUILD_TYPE=RELEASE .. make
Finally, to install (not really required) :
The last step isn't essential if you are developing your own code, since the most natural way of doing this is to create a cmake build of your own source tree, and that can be encouraged to link directly into the 'release' code built above.
