Error building openCV - dumpOpenCLDevice() method error

edit

I have been trying to build opencv for over a week now using the instructions at

http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html and http://miloq.blogspot.com/2012/12/install-opencv-ubuntu-linux.html however every time I get to the 'make' step, I get an error:
