[odb-users] Error in compile

[nima chavooshi]

Hi everybody,

This is my first email to this mailing list. I intend use ODB in my
project.(will be a open source network tools). So I am checking and writing
some test program. I could compile sample code without any issue. In the
structure of my code, I have 2 classes, person and contact(the attached).
The person class contains contact class as a member.
I did compile the header of classes with "odb" compile. but during
compiling of "person-odb.cxx" I have got the error below:
