Dear Ladies and Gentlemen,
I am developping on an Ultrix 4.2 and I use your
g++ 1.4
and gcc 2.1
I can't read news so I have a question if the following is a
bug of this old version or not!
I have a base class and a derived class. I use destructors:
e.g.
class A
{
A(); //Constr.
virtual ~A(); //DESTR.
//body
}
class B:public A
{
B(); //Constr.
~B(): //Destr.
//more code
}
Stroustrup says this should work, it produces the following output:
_$_8A
_$_20B
Why?
If I use this:
class A
{
A();
~A();
//virtual functions following
}
class B
{
B();
//code for virtual functions in class a or definition
}
I get the output:
warning: class A has virtual functions but non-virtual destructor.
I need help, else I can't go on working, or only withou
destructors . Is a bug of your compiler or linker and is fixed
in the newer versions or is it a feature or is it correct?
Thanks
