Hi Mathias

QuantLib comes with preset configurations e.g.

    configuration - Debug
    run-time library - Multi-Threaded Debug
    output - QuantLib-vc71-mt-sgd-0_3_9.lib

and the one you want

    configuration - Debug MTDLL
    run-time library - Multi-Threaded Debug DLL
    output - QuantLib-vc71-mt-gd-0_3_9.lib

Your approach of editing the 'Debug' configuration ought to work but
it's easier to just use 'Debug MTDLL' instead.

Also
- You should be able to use QuantLib in a DLL and your approach looks OK
- QuantLib depends only on the Boost header files not the libs
(QuantLib test-suite depends on the boost libs)

Regards
Eric
