Install error on Windows Vista

[toto]

Hello,

I'm trying to install Tahoe on Windows Vista but when I execute "C:\Python27\python setup.py build" I get this error :
Setting up environment to run scripts for the current user...

Already done: associate the filetype .pyscript with Python.File for the current user.

Already done: add .pyscript to the user environment variable PATHEXT.

Already done: add .pyw to the user environment variable PATHEXT.

Thank you for your help

I had success after editing C:\Python27\Lib\distutils\cygwincompiler.py to remove all of the -mno-cygwin options in Windows XP with Python 2.7.

Hm, toto, killyourtv, is there anything that Tahoe-LAFS should do to deal with this issue? I'm inclined to close it as "not our problem".

It seems like a bug in distutils, but maybe it could be worked around in zetuptoolz. If we close this ticket, let's first report the bug in distutils.

I changed AdvancedInstall to mention the workaround in comment:2, although I'm not entirely sure it is a good idea:

I'm not sure, tbh. I made my mods after seeing it on a mailing list post somewhere (maybe even tahoe-dev?). What I did may even be a horrible, cringe-worthy idea but it did allow it to proceed and tahoe seemed to work just fine in the afterwards.

This is an issue in python distutils:

Closing this ticket with the newly created "resolution" somebody else's problem. Thanks for the bug report!
