[odb-users] Enum encapsulation + getters / setters + query

[Andreas Pasternak MT-Robot AG]

Hello all,

I reorganized a bigger code project into smaller libraries. Now I get  
the following linker error:

undefined reference to 'typeinfo for odb::boost::date_time::special_value'
undefined reference to 'vtable for odb::boost::date_time::special_value'

I link to odb aswell as to boost datetime. I have no clue where this  
error is comming from. Its happening in the last step when linking the  
executable.

Best regards, Andreas
