A recent pacman -Syu revealed that world/quazip-qt5 and world/quazip-qt6 would install same files to the filesystem but are not marked as conflicting:

pacman -Sy --asdeps world/quazip-qt5 world/quazip-qt6:

It looks like quazip-qt5 is wrongly providing Qt6-related files. (Why??)

Regards!

The PKGBUILD requires the following to get the include files in the correct location.
The modified build section:

build() {
  cmake -B build5 -S $pkgbase-$pkgver \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DQT_DIR=/usr/lib/cmake/Qt5 \
    -DCMAKE_QT_MAJOR_VERSION=5
  cmake --build build5

  cmake -B build6 -S $pkgbase-$pkgver \
    -DCMAKE_INSTALL_PREFIX=/usr \
    -DQUAZIP_QT_MAJOR_VERSION=6
  cmake --build build6
}

Once completed:

ls pkg/quazip-qt5/usr/include/
QuaZip-Qt5-1.4

Thanks, @jspaces, for providing information how to fix it.

Now we have to wait until the maintainers pick it up.

Shouldn't such conflichts be automatically detectable by "sanity checking scripts" on the built packages, btw.?

I believe the main constraint would be sufficient time to find issues during the testing phase.
Everyone is a volunteer. They do the best that they can with available time to get stuff out.
I for one do not get upset if a library or a package conflict occurs in a rolling distribution.
That is the price of being free of whole OS installation cycles in regular scheduled release distributions.

Maybe I am too naïve, but my thinking is if on the distribution's infrastructure there would be automated testing actually the work of the volunteers would be _lowered_, especially since recently there were many issues.

Regards!
