Run-Time Type Identification And Destructors
Go Up to Run-Time Type Identification (RTTI) Index
When destructor cleanup is enabled, a pointer to a class with a virtual destructor can't be deleted if that class is not compiled with run-time type identification enabled. The run-time type identification and destructor cleanup options are on by default. They can be disabled from the C++ page of the Project Options dialog box, or by using the -xd
and -RT
command-line options.
Example
class Alpha {
public:
virtual ~Alpha() {
}
};
void func(Alpha *Aptr) {
delete Aptr; // Error. Alpha is not a polymorphic class type
}
