You forgot to include the file where the class is. For example where the 
constructor is declared. Just be shure that ld receive all the .o files that 
needs. The virtual table of the class is the table that says where are the 
virtual members (just pointers) needed to create an instance of the class.

Don't try (you can but you want that), just use -g3 to include full debug info 
and then GCC (or ld) will say the line.
