[IBPP-DISCUSS] IBPP compile error

[Jozo L. <joz...@li...>]

Dear All,
I'm a beginner in programming so please be gentle….
I'm running Qt5.8. with MinGW, also installed Firebird3.
I'm sending the content of my .h, .cpp, .pro file and compile output.
Could you please look at it and give me an advice how to resolve this.
Thanks in advance and kind regards.
Jozo
