Bug 1698243

Noticed the same issue in uptodate F30 system with ktoch-18.12.3-1.fc30.x86_64. Tried to `strace` but couldn't identify the root cause. Any pointers?

Additionally, found a launchpad bug report with some analysis already done --- https://bugs.launchpad.net/ubuntu/+source/ktouch/+bug/1827767. Seems like 19.04 version is required to fix this?

No upgrade required (but that will come sooner or later), just need a build with QtQuickCompiler feature disabled.  I'll get to work on doing that.

That'd be cool. Thanks Rex!

Just wanted to confirm that bug. Freshly clean installed Fedora 30, ktouch version as mentioned by Rajeesh is 18.12.3-1.

Other KDE apps like Kile and Okular do work.

This is still a problem in Fedora 31.

ktouch-19.04.3-2.fc31.x86_64

$ ktouch 
qrc:/qml/main.qml: File was compiled ahead of time with an incompatible version of Qt and the original file cannot be found. Please recompile

I managed to rebuild from source rpm today, not sure why but rpmbuild didn't create a executable for me, but manually doing 
cd BUILD/ktouch-18.12.3/
mkdir build
cd build
cmake ..
make
src/ktouch

worked for me. Obviously, I'm no build expert here, but I'd guess the fix is a simple matter of just recompiling the thing?

I tried to install on Fedora 30 with

    dnf update --enablerepo=updates-testing ktouch

but it didn’t install anything, just said 

    Fedora 30 - x86_64 - Test Updates                                    2.3 MB/s | 7.2 MB     00:03

    Nichts zu tun.
    Fertig.

Then tried with 

    dnf update --releasever=31 ktouch

which resulted in two new packages 

    kqtquickcharts             x86_64             19.04.3-2.fc31               fedora              80 k
    ktouch                     x86_64             19.04.3-2.fc31               fedora             4.6 M

When starting the same bug ''compiled ahead of time'' ocurred.

I now tried to compile it manuelly from source. First did

    git clone https://anongit.kde.org/ktouch

then went into the ktouch directory I just cloned and started

    ./build-install-run

which showed me that I needed these extra packages, which I then installed

    dnf install extra-cmake-modules qt5-devel kf5-kdoctools-devel qt5-qtquickcontrols2-devel qt5-qtquickcontrols2-devel kf5-kcompletion-devel kf5-kconfig-devel kf5-ki18n-devel kf5-kdeclarative-devel kf5-kwindowsystem-devel kf5-kwidgetsaddons-devel kf5-ktextwidgets-devel kf5-kcmutils-devel kf5-kitemviews-devel kf5-kxmlgui-devel kf5-kiconthemes-devel

And for correct keyboard layout detection (not necessary):

    dnf install qt5-qtx11extras-devel libX11-devel libxkbcommon-devel libxkbcommon-x11-devel libxkbfile-devel libxcb-devel
Again the building, installing and running with 

    ./build-install-run

which resulted in the following new bug:

The fixed builds are not available in updates-testing yet, they are currently in a "pending" state unforuntately.  Appears there have been some infrastructure issues preventing updates pushes since before the holidays.  Hopefully this will get resolved soon.
