QuantLib

[Arend]

Hello,

I want to make use of QuantLib, especially for converting a date into a serialnumber.
When I run the program below I get the error:
mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall QuantLib:ate:ate(int,enum QuantLib::Month,int)" (??0Date@QuantLib@@QAE@HW4Month@1@H@Z) referenced in function "private: class QuantLib:ate __thiscall MainWindow::date1(void)const " (?date1@MainWindow@@ABE?AVDate@QuantLib@@XZ)

I tried a lot, but still can't figure it out.
Can someone give me a hint?

Regards,
Arend

Added after 23 minutes:

I solved it: added #include <ql/auto_link.hpp> somewhere in the program.
