Thanks the suggestions from all of you. I shifted to build the opencv-3.0-alpha, rather than master branch on github repositories. Then the building process succeeded.

Hi, all,

I had downloaded opencv 3.0 master branch. (Before I had installed basic required packages for installing opencv)

After cmake it, and make, I came across the following build error :

==================================================================

compilation terminated.

==================================================================

It seems that the package cannot find "Eigen/Eigenvalues". Does it mean that I missed some prerequisites in my system? Hope someone could give me some suggestion to fix it?

P.S. My system is Ubuntu 12.04

Best regards,
