C++ issue

Pyrex gurus,

  I am trying to wrap a C++ library and have been successful for the 
most part (thanks to you guys).  One of the classes that I need to wrap 
does not contain a default constructor (see code below ).  The cpp file 
that gets created complains that "foo" does not contain a default 
constructor [ cdef foo f  is invalid ].  At the same time, I cannot say 
"cdef foo f = b.getFoo()". My solution was to build the cpp file from 
the pyrex code below and then create a line that says;

cdef foo f = b.getFoo() instead of  "f = b.getFoo",

and remove the initial declaration.  It works for what I am doing, but I 
am afraid that there could be some reference count issues.  
Unfortunately, the argument required by the constructor of foo class is 
neither required nor available in my wrapper code.

Any Ideas ?
thanks in advance.

------------------
class foo {
    public:
        foo( templatedClassObject  unAvailable );
        int (*getItems) { return 1; }
};

class bar {
    public:
        bar();
        foo& getFoo() { return fooObj; }
};

pyrex:

cdef extern from "foo.h":
    ctypedef struct foo "foo":
        int (*getItems)()

cdef extern from "bar.h":
    ctypedef struct bar "bar":
        foo (*getFoo)()

    bar *barFactory "new bar"()
    void deleteBar "delete "(bar *barObj)

def test():
    cdef    bar   b
    cdef    foo   f
    ### b is populated through some calculations here
    f = b.getFoo()
