Subject: subclassing SWIG generated c++ class

hi all,

I've created simle c++ class

--- class.cxx ---
#if SWIG
%module myext
#endif

class Foo {
	Foo () {};
	hello_world () {};
};

and then generated ruby extension module 'Myext' using SWIG for it...=20
no problem so far, I'm able to require the extension,=20
create instances of Foo, invoke methods, etc.

but when I try to subclass such class in ruby, the original class gets
always created, am I missing something, e.g.

--- test.rb ---
require './myext.so'

module Myext
	class Bar < Foo
	end
end

k =3D Myext::Foo.new
puts k
k1 =3D Myext::Bar.new
puts k1


both .new statements create instance of Myext::Foo...

ruby 1.6.7 (2002-03-19) [i386-linux]
swig 1.3.11

I'm now trying the cvs versions of SWIG and ruby, but if anyone knows what's
happening...

greets,
martin
