Hi, I got the exact same result with the git repository of dbus4win. I also tried the big patch you submited, but I still got the same error about version macro not defined. Sincerely Julien <div class="gmail_quote"> 2009/11/22 Tor Lillqvist <<a href="mailto:tml@iki.fi">tml@iki.fi</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Well, I don't think anybody claims that the upstream dbus is necessarily even buildable on Windows currently. That's why there are two forks of it (or actually of the dbus-1.2 branch I guess). You might have better success if you try to build either windbus (from sourceforge) or dbus4win (from git://<a href="http://repo.or.cz/dbus4win.git" target="_blank">repo.or.cz/dbus4win.git</a> , use the dbus4win-noncetcp branch). --tml </blockquote></div>
