And now a question about OOPs and Lightspeed C.  I have some code that
builds on a superclass and each of the subclasses uses only new
methods but no new instance variables.  It's pretty straightforward.
I have each subclass in a .h file and the methods in .c files for each
of the classes.  Then I compile and link and the linker tells me my
methods aren't defined!  Yet the methods are delcared in the class
definitions and the methods most certainly do exist in the files
compiled.  Yes, each of the methods is preceded by the subclass
name...

Link::getALink(void *, KEY_TYPE zot)
{
}

etc... and the subclasses look something like this...


struct classA : primeClass {
	void *constructor(void);
	void getALink(void *, KEY_TYPE);
};

yet MANY of the superclass methods come up undefined.  ANyone have a
clue as to what's going wrong?
