Summary0003514: Drop support for compiling with Qt4 (in favor of Qt5+)
DescriptionIn ticket 0003503 AOSP questioned why Doomseeker is still supporting Qt4, which hasn't received updates in many years. It's also not technically supported by Doomseeker since release 1.1.

A benefit of dropping Qt4 outright would be "better ability to use C++11/14", according to Blzut3.
Additional InformationCreating this ticket, so that discussion in ticket 0003503 doesn't get lost and this ticket becomes searchable for answers.

Qt4 is required to use Doomseeker on OpenBSD, until 0003494 is resolved.

Closing for obvious reasons, this has been discussed. Reopen once more relevant.

So, right now Doomseeker does not compile in qt4. While probably I could try to patch it, I'd honestly consider dropping support for qt4. I understand that unsupported platforms seem to rely on it (0003494 though I'd need to test it based on the last comment.), but considering that we're now working to bump the C++ standard and that also Windows is no longer an issue, I think it's the right time :)

Ok for me to drop Qt4.

Quote from Pol M
(0003494 though I'd need to test it based on the last comment.)

The author of that comment tested it to be working with Qt4, but said "nevermind" because the issue was reproducible with Qt5 only.

Just to keep the relevant information on this topic up-to-date: the unsupported platforms no longer need qt4 to use doomseeker, meaning that right now there is no longer a reason to still support compiling in qt4.

Removing Qt4 is fine by me too.

(Wedging this issue back to Pol M for assignment, while subscribing Blzut3 to this ticket for an answer to get its status "confirmed" or rejected. The "feedback" status would be wrong, because it asks for feedback from the reporter inappropriately in this situation.)

Go ahead! As noted in the ticket description I've said that Qt4 was unsupported since 1.1 was released, and that we just lacked an excuse to go out of our way to rip it out. We have that now.

I think that the best approach will be to remove the option from the cmake scripts. I could go on to remove the #ifdef conditions, but I don't think that's necessary. Of course, if you consider that removing them is needed, I'll do so.

It would be a good idea to just rip the band aid off and get rid of the ifdefs as well. They should be easy to find by searching for QT_VERSION and there's only tens of them. Otherwise they'll just linger around forever.

Pr coming, what will be missing will be the mac scripts (I have no mac to test the scripts on, so I'll leave that to someone with easier access to one) and the docker image. The reason I have not changed the docker image is because Ubuntu 14.04 is no longer on support, and we should move to 16.04. This will probably allow us to bump even more the C++ standard and who knows what else, so I decided to create a ticket for this and consider my job on this ticket done :)

Commits in red feel good.

There's also a tools/wadseekerapp/ that still links with Qt4. If you wish you can take care of that too, Pol. Otherwise reassign the ticket to me and I'll take care of the Docker image.
