how to get a working JCC for python running in Cygwin windows to try PyLucene, or how to get a working PyLucene.

thanks in advance

  Edwin,

If you can get this all to work with the cygwin compiler chain that's great. 
Please contribute potential patches back and your platform of choice will be 
supported. As it is, no one - at least that I know of - is using the cygwin 
compiler chain to build and use PyLucene with JCC on Windows.

At this point you can decide if you'd like to get it to work - and that's 
going to be taking some extra work from you since no one else on this list 
has stepped forward with solutions - or you can switch to the compiler most 
everyone else using PyLucene/JCC on Windows is using which is some version 
of Microsoft's Visual C++. When I test PyLucene on Windows, I use MSVC 7.1 
on Windows 2000. Newer configurations are known to work just as well.

There even is a free (as in $) version of that compiler available:
    http://www.microsoft.com/express/download/

If you go this route, be sure to use a version of Python that was compiled 
with MSVC (or build it yourself).

I know of another person using yet another compiler on Windows called 
MinGW and, as far as I know, they got it to work. I don't have the details
but I'm sure if you ask on this list, they'd provide what they know.

On another note, you seem to be using JCC 2.1, why ?
The current version is 2.3.

Andi..
