Hi Zoran,
I compiled the packages as you said, and each one stopped at line 84 in unit zClasses, which says
tContainedObject = Class(tAggregatedObject, IInterface),
and gives the error
No matching Implementation for Interface method "IUnknown QueryInterface(constref,tGuid,out<Formal type>):Longint,StdCall;"found
This is ZEOSDBO-7.0.0-alpha.
The project I'm working on is a data migration to move from FireBird 1.5 to SQL Server.
