How can I download and build opencv on a raspberry pi, but using C? i want to program in C and all the instructions I have seen about the Raspi and Opencv is by using Python. Does anyone know if this is possible? thanks
Well, I ran into the same issue. I'm perfectly happy to code in C++, but I had some existing code written in C that I wanted to tie into as well without having to re-code it in C++. Fortunately, it's possible to do both-- I ended up creating a simple C++ file that wrappered the necessary calls for C, and then was able to add my C source and call the C++ functions as needed. It works fine and wasn't very hard to do. In my case main() is in C but it can be done the other way as well with C++ calling C. Now I have a project with a makefile that includes the two source files (right now there's only two because it's a very simple project), where I can code stuff in either C or C++ as is convenient and just put it in the right file for it...

the good news is, that you can use c++ for coding on a raspi, too.
the bad news (if you really meant C) is, that they moved away fom the arcane c-api long years ago, it's no more developed, and you can only reach half of opencv's functionality. - so you really should not start any new project using that.
All hail to @berak! Lets stop encouraging people using the C-API!
Give C++ a try and install OpenCV and QT Creator on your RPI I haven't documented how I installed them, but it works for me: http://www.realgentlemen.dk/MediaWiki/index.php?title=Raspberry_Pi_Cameras
