Update to Qt6

[bkmgit]

Addresses https://github.com/wedesoft/anymeal/issues/66 Initial review would be helpful

[bkmgit]

There is a bug that prevents builds on Ubuntu 22.04 without unusual modifications https://bugs.launchpad.net/ubuntu/+source/qtchooser/+bug/1964763

[wedesoft]

Looks good. Please add the link to Fedora instead of replacing the link to Arch. It is failing the GitHub Workflow builds. Maybe there is an image for ubuntu-24.04? Will have a look when I get the time.

[bkmgit]

There are two links for Arch

• Arch Linux
• Archlinux user repository page which both point to the same location. Are they both needed?

[bkmgit]

Fedora build works. Ubuntu and Windows need updating. Build on Ubuntu 24.04 also needs an update.

[wedesoft]

Ah ok, if the Arch link was duplicate then it is fine to remove. Sorry

[wedesoft]

Maybe you can use pkgconfig (PKG_CHECK_MODULES) to find the Qt6 libraries. I haven't checked whether the Windows MinGW packages have pkgconfig files though. I haven't figured out yet how uic, rcc, and qtchooser works.

[bkmgit]

Ubuntu build now works, Will need to re-enable caching. It may be better to switch to CMake rather than using pkgconfig, but this is probably best done after the update to Qt6.

[wedesoft]

It fails on my machine because /usr/bin/moc generates code for Qt5. Not sure how this works. /usr/bin/moc is a symlink to qtchooser on my machine.

[bkmgit]

If both Qt5 and Qt6 are installed, may need to ensure moc-qt6 is picked up. There is an example configuration for gpgme at https://github.com/msys2/MINGW-packages/blob/e858872a3b4d7ee9bfdc40f41aaead2bfc519186/mingw-w64-gpgme/0001-fix-find-moc-qt6.patch#L6

[wedesoft]

Ah, I saw your workflow changes. I got it to work now using PATH=/usr/lib/qt6/bin:/usr/lib/qt6/libexec:$PATH ./configure --prefix=/usr.

[wedesoft]

Ok, it compiled successfully. However the SVG icons are not showing at the moment.

[wedesoft]

Ok, I had to install libqt6svg6

[bkmgit]

Thanks. Still looking for QT_MOC and QT_UIC on Windows.

@wedesoft Are you able to test on Windows?

Hi. Yes, I have Windows 11 and Debian 12 here.

Hi, can you merge https://github.com/bkmgit/anymeal/pull/2 into your branch? It contains several fixes.

I couldn't find windowsprintersupport.dll for Qt6 on my system. Maybe that DLL is not needed any more?

qwindowsvista.dll and windowsprintersupport.dll seem not to be in the core packages. qwindowsvista.dll is mentioned in the documentation https://doc.qt.io/qt-6/windows-deployment.html#qt-plugins but not sure if it is still needed. Maybe check if Windows build runs ok?

[wedesoft]

Looks like it built. Congrats!

Will address further feedback in the next day or so. Once ok, can clean up commit history.

According to https://packages.msys2.org/packages/mingw-w64-x86_64-qt6-base qmodernwindowsstyle.dll should exist. Strange.

[wedesoft]

Will try pacman -Fy and pacman -Fx filename when I find the time (also see here).

qmodernwindowsstyle.dll does exist. I have not been able to find qwindowsvistastyle.dll and windowsprintersupport.dll but do not know if they are still needed for correct functioning of the Anymeal on Windows.

[wedesoft]

Ok, windowsprintersupport.dll is not in any qt6 package according to pacman.

[wedesoft]

Tried the installer and libb2-1.dll was missing.

[wedesoft]

Printing works!

[wedesoft]

Hi, can you pull in https://github.com/bkmgit/anymeal/pull/3 ?

[wedesoft]

Hi, can you merge https://github.com/bkmgit/anymeal/pull/4 ? I think then it is ready to merge.

[wedesoft]

Thanks! Great work!

[bkmgit]

Welcome, thanks for the fast feedback.
