I am trying to create a derived class from the Opencv3.0 SVM in the following way and I get an error. Can anyone suggest a solution for this? Thanks in advance.
class MyClass: public SVM
{
}
int main(void) { MyClass *mysvm = new MyClass; }
This defnition is generating the following error while compilation:-
