question about reloading assignment operator =

[wang lei]

hi all!

my ocatave is 2.9.9 on debian testing.

In make_int.cc assignment operator = is not reloaded. To reload it I add
these sentences in make_int.cc:
class octave_integer{
public:
...
void assign(const octave_integer& t){ scalar = t.scalar; }
private:
...
};

DEFASSIGNOP(assign, int1, int2){
CAST_BINOP_ARGS(octave_integer&, const octave_integer&);
cout << "assignment" << endl;
v1.assign(v2);
return octave_value();
}

DEFUN_DLD(make_int, args, , " ")
{
static bool type_loaded = false;
if(!type_loaded){
...
INSTALL_ASSIGNOP(op_asn_eq, octave-integer, octave_integer, assign);
...
}
...
}

and mkoctfile and type "a=make_int(10);b=make_int(20);a=b;", but nothing
happened. why?
