--- Comment #57 from Yue Liu <m...@outlook.com> ---
I just ran into Qt6 compilation issue as well. I'm compiling digikam master
HEAD against the latest kf6-qt6 packages from kde-neon/unstable. This is after
KF6 has branched so not sure if that requires changes on digikam side.
I had to replace all the `KF5` names in cmake files to `KF6`, not sure if this
is really needed, or an ECM packaging issue in kde-neon, or I just forgot to
install some KF5 compatibility packages.
Then found I have to add additional Qt libraries such as `StateMachine` and
`Core5Compat`.
Then need to replace "I18N_NOOP2" with "kxi18nc"
Then ran into multiple compilation errors related to ambiguous type
conversions:
```

If digikam was compiled with Qt6 successfully with a previous Qt6 and previous
KF5-qt6 build, I don't think these compilation errors need to be fixed right
now, there must be some compatibility flag to allow the old code to compile.
I'm I missing anything from the CMAKE configuration?
I'm setting this environment variable to find ECM packaged in kde-neon:
```
ECM_DIR=/usr/kf6/share/ECM
```
and using this Cmake config:
```
cmake -G "Ninja" .. \
-DCMAKE_BUILD_TYPE=RelWithDebInfo \
-DCMAKE_INSTALL_PREFIX=../usr \
-DBUILD_TESTING=ON \
-DBUILD_WITH_CCACHE=ON \
