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:

So it was a flag that was not set?

@berkut , @genaro , - it's probably a good idea now, to find out, which AV* releated libs you're trying to use, and which version of it is the correct one.

@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?

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

one work around to solve this issue is to set the WITH_FFMPEG = OFF when building. It worked in my case.

I posted what worked for me on stackoverflow, where I also have a link to my OpenCV issue tracker post.
