qt3-static, qt-static use-flags

[misterjuiceman]

I'm about to install www-client/opera-9.51 and I noticed the qt3-static and qt-static useflags were available. It seems they're used for opera and skype, but I have no idea what they do compared to the qt3 and qt4 flags.

qt-static and friends use a built-in qt for opera which avoids dynamic linking to your standard qt. As a result you'll have at least two qt-s on your system, the shared one, and one exclusively used by opera. If you enable that use flag, you'll notice that the download will be larger: that's the additional qt.

This may be useful to avoid version incompatibilities. You should also use it if you want to run opera from X or on xfce and don't want to drag in qt (which is huge). If you're on KDE, however, you shouln't need it.

just to make this a little more clear, static means static linking. The needed libraries are built into the binaries at compile time. You might use qt-static if you have just one qt program running. I have a skype with qt-static running on a 64bit system because I don't want the emul-linux-x86-qtlibs pulled in.

Also qt-static in opera atleast pulls in opera statically linked to qt4 library that means it will have an internal qt4 library
and qt3-static will have opera statically linked to qt3 library.
Opera doesn't have at package built against shared qt4.
So if you are on a system with mostly qt4 things like a system with kde4 and you don't want to pull in qt3 in a new slot then you might want to use the qt-static

ok thanks, so if im running kde 3.5, and I don't use any of those flags, opera will use the standard qt3 library?
