Re: [gentoo-amd64] mythfrontend on AMD64 - will it work with qt-4? (cannot connect to database)

[Raffaele BELARDI]

I'm also experimenting with mythtv on an amd64, but for now I have
frontend, backend and mywql running on the same diskless machine so I
don't have direct answer for you. But in my system the frontend works fine.

If memory serves (I'm on a different system now), during the emerge of
mythtv qt3 library was pulled in, not qt4. That was a couple of weeks
ago, at the time there was no qt3support flag yet, or I did not notice
it. Maybe you could try emerging qt-3 instead of qt-4 with qt3support

bye,
