Hi,

Thanks for your replies, I found it finally! Indeed as Peter suggested
the autolinker thing was missing, so adding:
#include <ql/auto_link.hpp>

to the main file fixed the issue. In the project that worked Lorenzo
added the whole #include <ql/quantlib.hpp>, so I didn't even realize
that the autolinker was needed and that it was hidden inside it!


Cheers,
Grzegorz
