[gentoo-user] Howto get rid of USE qt3support

[Rudmer van Dijk]

Hi,

there is a new qt and kde available, but it still has the annoying USE flag 
qt3support... is there a way to get rid of it? a lot of kde packages are 
complaining about qt3support and I don't want it.

qt3 left my system a couple of years ago!
so this is starting to get really annoying 8-(

Hi,

I think qt3support enables Qt3-compatible APIs in Qt4, but I don't
believe it causes you to pull in any actual Qt3 packages. I think it
is mainly to ease transition from Qt3 API to Qt4 API for porters. (I
don't think Qt3 is even in portage anymore)

What Paul said.  qt3support is needed by some Qt4 programs and it's not 
optional.  If a program needs it, there's no way around it.

But it's nothing you should be concerned about; qt3support is part of 
Qt4 itself.

ok, thanks.
it's just that it sounds so old and I'm running ~amd64... 
but since you have no control yourself why not de-USE it or make it a forced 
USE?

I'm not sure.  My guess is that it's needed in order to trigger a 
rebuild and that it's not enough for a package to depend on 
x11-libs/qt-qt3support; the other qt-* libs must be rebuild.  I think :P
