I would like to find out what version of OpenCV is installed on my computer (i am running Ubuntu 10.04). Is there a simple way to check it if ? If not then can i find out the directories where files (samples, etc) are installed ?

I am trying to run some code that i have already tested on another computer with OpenCV 2.3 installed and i get many errors.

The other methods here didn't work for me, so here's what does work in Ubuntu 12.04 'precise'.

On Ubuntu and other Debian-derived platforms, dpkg is the typical way to get software package versions. For more recent versions than the one that @Tio refers to, use

 dpkg -l | grep libopencv

If you have the development packages installed, like libopencv-core-dev, you'll probably have .pc files and can use pkg-config:

 pkg-config --modversion opencv
