SWIG: ImportError: dynamic module does not define init function

[Louis Luangkesorn]

I'm trying to run the example from the SWIG User's Guide (V 1.1 June 23,
1997)  When I try to load the example I get the following:

PythonWin 2.1 (#15, Apr 19 2001, 10:28:27) [MSC 32 bit (Intel)] on
win32.

>>> import cnumint
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
ImportError: dynamic module does not define init function (initcnumint)
>>>

I've noticed on various mailing lists several people have asked this
same question, but I have not seen anyone respond to this.  Is there
something I'm missing?  Thanks.

Oh, when I compile, I get a "Bad command or file name" error, but the
dll continues to compile with a 0 errors, 0 warnings message.  Thanks
for your help.
