What's actually involved in wrapping a C++ class?
The docs say I have to provide a class that contains the C++ instance
pointer, but it doesn't say what to do with the instance pointer once it's
in the scheme object, and how to wrap access to C++ functions and values.

Hello,
well, binutils tells us that
$ c++filt _ZTV6Square
vtable for Square
So the shared object you built apparently does not link
I tried to get the following class example from swig running:
/* File : example.cxx */
#include "example.h"
#define M_PI 3.14159265358979323846
/* Move the shape to a new location */
void Shape::move(double dx, double dy) {
x += dx;
y += dy;
}
int Shape::nshapes = 0;
double Circle::area()
