Arch Linux User Repository

@semeion,

qt4 was expelled from the official repositories due to https://lists.archlinux.org/pipermail/arch-dev-public/2019-April/029560.html

It will not be restored, because software needs to stop using qt4. It's fine for people to still use it via the AUR if they have old software that is not ported, but the proper solution is to get that software ported to qt5.

"It takes a long time to compile" is not a reason to move it to community.

@xuanruiqi,

Only Developers and Trusted Users have access to pkgbuild.com, and we will not be uploading qt4 there. If we wanted qt4, we would upload it to community, but we don't -- we have managed to move every package still being actively maintained in the official repos, over to qt5, and we want to stay that way.

...

Again, the proper long-term solution is to get software ported over to qt5.

For those who have problems with ‘std::tr1’ has not been declared error: build in clean chroot with extra-x86_64-build script.

Build in a clean chroot. I can build fine.

Getting this error:

messagemodel.cpp: In function ‘int calcMergeScore(const DataModel*, const DataModel*)’:
messagemodel.cpp:186:61: error: ordered comparison of pointer with integer zero (‘MessageItem*’ and ‘int’)

Need this patch for GCC11.

Warning: this also fixes a bug, because that check never worked as intended. If that is not desired, just remove the if but keep the body, because the condition was always true with gcc < 11. (See https://godbolt.org/z/n6Wxsz9Mj if you need convincing.)

As patch for the PKGBUILD repo:
