Hi, i would like to install another OpenCV version (my current is 2.4.2) because SURF is not rotation invariant. Will there be any problems so that after installation of the new one the current version is not working correct? Is there something to consider?

What is your operating system? On Windows you can extract archive to any folder and include different OpenCV versions in different projects without any problems. On Linux systems all 2.4.x versions of OpenCV are installed in the same folder by default, so you can get conflicts. The only solution is to get OpenCV from official size, not from distro repository, extract it to custom folder and update environment manually.
Since OpenCV 2.4.2 all official versions of OpenCV are binary compatible. So you can update OpenCV up to the latest version without any code changes.

Hi. I'm working with VS2010. So i can build the new OpenCV to another folder and create a new propsheet with the specific path to the include-, lib-files,... in VS. Then it should work?

Yes, it will work.

How can I specify to pkg-config which version I want to use, and where it is installed?
