Yes, of course. My guess would be:

1. You did not compile contractor.hpp with the ODB compiler.

2. You did not compile and link the resulting contractor-odb.cpp
   into your application.

3. You packaged contractor-odb.cpp into a static library and since
   you did not reference contractor in your application, it did not
   get linked.

For (3), see:
