Hi. I have no experience with OpenCV. I'm trying to install OpenCV on Ubuntu 12.04 but am encountering errors.
To install OpenCV, I am following instructions at http://karytech.blogspot.com/2012/05/opencv-24-on-ubuntu-1204.html.
I get errors after I issue the 'make' command. I haven't been able to figure out how to get past these errors. Can someone help me?
Here are the errors I am getting:
