Forum OpenACS Development: Re: Aolserver and Windows Services for UNIX
I think PG for windows is in beta at this point.
Windows Services for UNIX was recently discussed on the AOLserver mailing list. I don't think anyone has managed to get the thread-enabled Tcl compiled on it yet.
I think PG 7.5 is not officially in beta yet, though the PG sources now compile natively on Windows, and nightly binary builds are available:
I tried an OpenACS install with a nightly build a few weeks ago but it wouldn't work out of the box and I haven't had time to investigate. I do remember thinking that the error looked more like a 7.4 -> 7.5 incompatibility than a Windows issue.
