Bug 520323

This will be fixed when (if?) we switch to using qt's phonon. (currently in rawhide, other releases when qt-4.5.3 lands)

Though I'm a little surprised, I thought Libs.private were only used for static linking ?

Looks like the dependency surfaces when building for example mythtv 0.22. The build log in the report doesn't look like a static build.

Maybe a pkgconfig bug exporting Libs.private to the external builds?

Another thing I'll just do is... since we're purposely not including static libs anyway, strip Libs.private from qt's pkgconfig files so consuming apps won't even try to use them.

Fwiw,

$ pkg-config QtWebKit --libs
-lQtWebKit -lQtDBus -lQtGui -lQtNetwork -lQtXml -lQtCore

$ pkg-config QtWebKit --libs --static
-L/usr/X11R6/lib -L/lib64 -lQtWebKit -lphonon -lQtDBus -lQtGui -lQtNetwork -lQtXml -lQtCore

Implies your build (mythtv) is purposely requesting static linking here.

It looks like all mythtv does is

using_qtwebkit {
        QT += webkit
        DEFINES += USING_QTWEBKIT
}

(that's all a case independent grep on all *.pro files yields)

Ah, likely coming from the qmake-fu in %{_libdir}/QtWebKit.prl

Ugh, the circular dependency is a little more madness than I'm willing to partake of, so my only suggestion is to workaround it by adding
BR: phonon-devel
until 4.5.3 lands.

(abusing closed->deferred as that closely matches the plan here)

But if it's marked closed->anything the workaround will never be applied, or did you commit the workaround to CVS?

As outlined in comment #1, this is fixed in rawhide already (by using phonon from qt directly, not standalone).  This is also planned to propogate back to previous releases (F-10, F-11) when 4.5.3 happens.

The workaround I mentioned was for apps with problems, like mythtv, to (temporarily) add 
BR: phonon-devel

But isn't adding the workaround to the qt package better (which carries the bug after all) than modifying N clients and later removing the temporary fix (or forgetting it forever there)? It looks like anything using the webkit is affected.

(Unless 4.5.3 into F10/F11 is something imminent - I have no idea how the schedule looks like - in that case waiting for the bug to go away is OK)

The problem is that the qt -> phonon -> qt dependency is circular.

The problem is that the qt -> phonon -> qt dependency is circular.

But the dependencies are run-time dependencies of *-devel packages, or not? Does it really matter? Such a circular dependency just means that the packages need to be installed together or not at all.

The circular dependency is a fact, you obviously need phonon-devel with qt-devel (when using webkit), and vice versa.

Re-opening, confirmed my suspicions regarding the .prl cause (comment #6)

And, we've backtracked/waffled a bit on our plan to use qt's phonon, so I'll at least fix the .prl file causing this particular issue.
