[C++] Good FOSS C++ Project to Get My Feet Wet In?

Question

Wanting to dive in to some FOSS contributions using C++ .

Any recommendations? If possible, I would like to keep using Visual Studio if possible. :P

Thanks SO!

Answer 1

As a roguelike fan, I can recommend Dungeon Crawl Stone Soup: http://crawl.develz.org/wordpress/downloads - unless you prefer toying with OpenGL and stuff, this is a nice project to study.

Answer 2

I would recommend getting your feet wet with the Gnu Scientific Library. It has (or at least had) a very clean code base you can learn a lot from by looking at it.

The first project I would try would be to write some unit tests for it. Most FOSS packages have terrible unit tests...

The second project I would try would be to rewrite some of the libraries to use http://en.wikipedia.org/wiki/Interval_arithmetic .
