I am trying to learn image processing and obviously opencv is one of the best options. Usually synaptic does all my installing work for me so I just checked the repos. But in the repos there is only on libcv1 and it is listed as 1.0.0-6.2ubuntu1. Does that mean it is version 1.0 of opencv? Also I found this page in community wiki

https://help.ubuntu.com/community/OpenCV

It says I need to install libcv4 which is not in my repos. I also downloaded the source but it uses something called cmake, never used it before. Is it similar to make?

In your case you have indeed version 1.0.0 of the library.

In general when you want to develop using a library, you have to get the corresponding -dev package which contains the header files. In this case libcv-dev. It will also install the library itself, which may have different version numbers depending on the soname - no need to install it separately.

In this case there is also a opencv-doc package, which contains some example programs, and which is worth installing.

If you want to build the library itself from source, you can run sudo apt-get build-dep opencv to get all the required libraries and header files to build opencv.

Building indeed uses cmake. It is a program which generates makefiles.

Here is a tutorial for installing the latest OpenCV 2.3.1 with Netbeans 7.1 as IDE.

I don't know if it installs build-essentials by itself, but the tutorial will definitly help you.
