[Interest] Qt5, XCB and X11

Just that the -qt-xcb setup has worked pretty well for the Qt SDK, so far. It was basically the outcome of a discussion I rasied on the xcb mailing list, before the 5.0 release:

http://lists.freedesktop.org/archives/xcb/2012-October/007928.html

But then again, we don't claim to support all distributions out there ...

My bet would also be that that ain't work because you will most likely end up with the dynamic libX11 library be pulled in somehow. But that's just my best guess :)

You've been saying SLED11 has xcb, but "does not provide up-to-date versions" of it. Does that mean Qt doesn't compile at all on SLED11 ? Or just that the static libraries compiled in with -qt-xcb don't run on it?

Maybe you can provide a specific build for this platform? Or 'downgrade' the xcb libs that are part of Qt sources to a compatible version?
