Arch Linux User Repository

Using an AUR helper such as yay to build packages including backintime is HIGHLY discouraged. The recommended build method is to use a clean chroot. See: https://wiki.archlinux.org/title/DeveloperWiki:Building_in_a_clean_chroot

I wrote a script that automates much of that called clean-chroot-manager offered here in the AUR.

Please stop posting build failures because you insist on building with yay or other AUR helpers.

There is a error for me:

#clean-up installed old files that were renamed or moved in later BiT versions
rm -f /etc/dbus-1/system.d/net.launchpad.backintime.serviceHelper.conf
rm: cannot remove '/etc/dbus-1/system.d/net.launchpad.backintime.serviceHelper.conf': Read-only file system
make: *** [Makefile:14: install] Error 1

what should I do?

In the newest version（1.4.3-2), the bug has been fixed. It works well now.

[sunshe35@archlinux tmp]$ yay -Qs backint
local/backintime 1.4.3-2
    Simple backup system inspired from the Flyback Project and TimeVault. Qt5 GUI version.
local/backintime-cli 1.4.3-2
    Simple backup system inspired from the Flyback Project and TimeVault. CLI version.

@graysky The python3 package "pylint" is missing and must be installed to run the unit tests (build & test dependency only). This dependency and "unit test" is new. It is just a static code analyzer and should not run during installation because it is very slow and does not add value to check the installation. I will ask the author of this code about options to improve this...

Edit: I have opened an issue for this: https://github.com/bit-team/backintime/issues/1634

Still fails for me:

@uffe @graysky I have fixed the make install Makefile bug in our "dev" branch now and it works on my machine now. Retests and feedback welcome :-)

@uffe

downloading the PKGBUILD and just executing makepkg gives the following error... I guess that messing with things outside the package staging-dir should not happen during the package phase..

I have introduced this clean-up code in BiT to support a migration scenario (as seen in the comment but indeed it looks like I forgot to prepend $(DEST)).

Is there a recommended way (best practice) for make install to make sure that old files (renamed or to be installed into another folder now) are removed during installation since make install does normally only overwrite files.

And if you use a different installation path with for make install (chroot/fakeroot) to copy it then into your system for installation: How can I as BiT developer make sure the old installed (but later renamed) file is removed for sure?

Edit: I have opened an issue, perhaps we continue our discussion there: https://github.com/bit-team/backintime/issues/1630

Indeed it was something to do with QGnomepPlatform. I use GNOME, and some time ago Back In Time stopped displaying the toolbar icons so I installed this both the Qt5 and the Qt6 versions (although in hindsight none of my apps use Qt6 yet) and it solved this problem back then. Now uninstalling the QGnomepPlatform packages allowed me to finally make the backintime packages and install them without error, and the icons are displaying just fine.

I was going to install QGnomePlatform again to look into this qqc2-desktop-style thing. Apparently just using adwaita-qt5-git and qgnomeplatform-qt5-git should work if I set QT_STYLE_OVERRIDE=adwaita. Apparently I installed such packages back when there were in the extras repository and now they are not anymore? Perhaps my problem was because they were old versions? Anyway, I was not able to install qgnomeplatform-qt5-git because its build script is failing for some strange reason; notifying its maintainer.

Thanks for your help!

UPDATE: Finally installed QGnomePlatform (and Qt-Adwaita) back, from the -git repositories linked to from the wiki page you linked to. My difficulty with installing then was solved by installing extra/qqc2-desktop-style5, which was also mentioned in the error message. Then I was able to compile Back In Time successfully and installing it without any problem.

@leonardof THX for the full unit test run output! I can see an unexpected INFO that causes the unit test to fail:

Create info file qt.qpa.qgnomeplatform.theme: The desktop style for QtQuick Controls 2 applications is not available on the system (qqc2-desktop-style). The application may look broken.

I don't know this specific Qt5 info and cannot reproduce it.

• Which desktop environment are you using?
• Have you changed the default desktop style to some other style (which one)?

I guess you can install a possibly missing qt5 package ("qqc2-desktop-style"?) to fix this:

https://wiki.archlinux.org/title/Uniform_look_for_Qt_and_GTK_applications#QGnomePlatform

It can be installed with the qgnomeplatform-qt5-git It does not provide a Qt style itself, instead it requires a style that support both Qt and GTK.

The source code of QGnomePlatform tells it is looking for a style name containing "org.kde.desktop":

https://github.com/FedoraQt/QGnomePlatform/blob/d86d6baab74c3e69094083715ffef4aef2e516dd/src/theme/qgnomeplatformtheme.cpp#L105-L111

#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
    // Unfortunately we only have a way to check this on Qt5
    if (!QQuickStyle::availableStyles().contains(QStringLiteral("org.kde.desktop"))) {
        qCWarning(QGnomePlatformThemeLog) << "The desktop style for QtQuick Controls 2 applications"
                                          << "is not available on the system (qqc2-desktop-style)."

        return;
    }

@dev_aryoda, thanks for checking!

The output follows. I don't know of any special configuration, I just git pull, makepkg --clean and, hopefully, sudo pacman -U. Optional dependencies meld, python-keyring and sshfs are installed, but kompare, enfs and pm-utils are not.
