I have been trying to investigate if there would be any benefit to adding r
value references to some MySQL++ classes, but I keep running into linker
errors in my application. So I spent ages looking for the problem in my
application and found nothing. However compiling the other examples (without
any of my changes) also caused the following linker errors, even though
MySQL++ compiles without any error.
I’m compiling this using VS 2010 on Windows 7.
Any ideas on how to solve this?

(I also get the same error messages for a few other examples that also make
use of streams.)
