Overview
I am still attempting to get pywin running using the Cygwin version of Python.
This is not so urgent now that I have worked out that I can run a Python script from the Cygwin shell which invokes the ActiveState Python binary and it uses the ActiveState internals.
e.g.
#!/c/PROGRA~1/ActiveState/Python/python.exe # #------------------------------------------------------------------------------- import os import sys import dbi import odbc import time import getopt import logging from datetime import datetime #------------------------------------------------------------------------------- ...
When attempting to install pywin under cygwin the install breaks as it depend on a _winreg (Windows Registry) module. Have found reference to a _cygwinreg.py - check to see if I have put it here if you are interested.
