Everyone, I'm still hoping someone in the community can help me get past the installation of OpenCV.

@berak, how can I do that? That is, how can I figure out which AV* related libs I'm trying to use, and which version of it is the correct one?

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/....

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:
