Hi.
Just asking out of curiosity. When Qt5 is released, what will be our packaging plan? Will Qt4 and Qt5 co-exist as Qt3/Qt4 do now?
regards,
Syam

Yes, of course. They are binary-incompatible and to some extent source- incompatible, so we cannot expect all software to instantly use the new Qt 5, thus a compatibility package will be maintained, as for Qt 3 (as long as it is needed, possibly "forever"). You will be able to have Qt 3, 4 and 5 installed all at the same time. (I still have no plans to drop Qt 3. Even if the other maintainers resign, I'll pick it up.)

So, I guess we will have a parallel installation of Qt5 with tools like "qmake-qt5" etc. That's good news for me. Has anyone tried packaging Qt5 beta for a parallel set-up with Qt4?
On a related note, any concrete ideas on the version of KDE that'd come with RHEl 7?
We use RHEL 5.3 at work for many mission critical workstations. We are quite agnostic to changes and haven't adopted RHEL6. But some recent PC hardware are making us use RHEL6 on some less important installations. In 2013 or 2014, when RHEL7 is released, I was curious if we'll have a good version of KDE to go with it. RHEL6 came with a very shabby KDE 4.3, (and without KDevelop). Perhaps I can port my applications to Qt5 (and incidentally Qwt 6.x) along with adoption of RHEL 7.
What do you think?

Yes, that's the plan.

Not yet, we're waiting on whether upstream reacts to our requests to make it easier to support parallel installation. We'd like to avoid distro-specific hacks to the extent possible.

Unfortunately, I cannot comment on that because I just plain don't know (in fact I don't even know whether a decision has been made yet), and those who do know are probably not allowed to tell you either.
What I can tell you is that it's unlikely to be a 5.x version because upstream development on a kde-workspace 5.x hasn't started at all yet. But the amount of support, if any, which will be given to Qt 5 and KDE Frameworks 5 is also something I don't know anything about.

Yes. Even I didn't expect KDE 5.x since I had heard that Fedora 18 would probably be the base for RHEL 7. All I hope for is a decent KDE, 4.9.x or even 4.10 perhaps. 4.8.x would be too old by the time RHEL7 is released.
Anyway, regarding Qt, I hope it comes out with a very new 4.8.x version. I can build and install Qt5 from Fedora src RPMs (this is pretty much what I did for RHEL5, except for some quirks with Phonon). That's why asked if it will be possible to have Qt5 & 4 in parallel.
Thanks for the excellent work in managing Qt & KDE.
