Ld: unsatisfied symbol "virtual table of baseclass"

HU-UX IA64 11.31 LD errors:

Ld: unsatisfied symbol "type info of baseclass" in file deriveclass. o
Ld: unsatisfied symbol "virtual table of baseclass" in file baseclass. O]

Because there is no realization of some functions declared in the baseclass. But it hard to find out, as there is no hints about the function's name.

So you can do as follows:

1) try to realize like:

Class baseclass

{

//.....

Virtual int funca ()

{Return 0;} // Add this line

//.....

};

 

2 declare those functions as pure virtual fuctions:

Class baseclass

{

//.....

Virtual int funca ()= 0; // Add "= 0"

//.....

};
