Mac OS X error at linking examples: Undefined symbols

I have been trying to compile your code, but as soon as it tries to link any example, it starts throwing a list of undefined symbols at the libraries:

I am using the 0.4.0 version located at the downloads sections.

Linking in the examples is messed up (mea culpa!).

Library was planned to be used like static library, and I don't why I went with shared approach... For my projects I am using in static manner. :)

Anyway, please try using cmake for building. Maybe building examples it's fixed. I am not maintainer of cmake stuff.
