I added :
#include
to CDBGeoCell.h
The compilation passed but I need to look up if that affects the program. I hope it didn't set that module as optional and now its not available during runtime.

[TaukSnarkyAgrud]

I, again, had this error on a different machine(fresh install of lubuntu).
I edited the .h files for CDBTile and CDBGeoCell and added the include:
#include
This fixed my compilation issue.
