QtCreator errors with QtGraphs QML
-
Hi,
Do you mean you have errors shown from the code model or is your code not working ?
-
Can you share a minimal compilable example that shows this ?
-
@SGaist If I can say this: I think its not a problem with my code. I think there is some software package for QtGraphs missing. In comparism with QtCharts, there is no
- libQt6GraphsQml6 -> /usr/lib64/
- qt6-graphsqml-devel -> /usr/include/qt6/QtGraphsQml/
When I tried to use QtCharts before, the remaining prompts were also not found by QtCreator, before I installed the corresponding devel packages from the repo ...

@Tobias83 said in QtCreator errors with QtGraphs QML:
LineSeries
do you have
import QtCharts 2.8
in Main.qml?
https://doc.qt.io/qt-6/qml-qtcharts-lineseries.html -
@Tobias83 I just realized you have 6.7. Qt Graphs went out of tech preview with 6.8.

@SGaist said in QtCreator errors with QtGraphs QML:
Graphs went out of tech preview with 6.8
What does that mean?
On my Computer I have libQt6Core6 6.8.2-3.2. I thought the libs are downward compatible. Should I change
find_package(Qt6 6.7 REQUIRED COMPONENTS Qml Core Quick Graphs)With changing in
find_package(Qt6 6.8 REQUIRED COMPONENTS Qml Core Quick Graphs)there is no change.

How did you install Qt ?
Which packages do you have ? -
That's why I am asking how you installed Qt.
-
Are you able to build and run any of the Qt Graphs examples ?

@SGaist OK, the hellographs example is working: hellographs on https://code.qt.io
I tried to make the same cmakelists.txt, but I don't know, whats the difference between my project and hellographs. There are some warnings in QtCreator like:

Did you nuke the build folder after these changes to ensure you start from a clean state ?
-
@SGaist I moved the build directory:
mv build-HardCore-Desktop-Debug/ build-HardCore-Desktop-Debug_old/Than I executed cmake file again, but I can't build the project and the project is not structered anymore. There is only a file list at the left site. The error in German language is:
:-1: Fehler: CMake-Konfiguration "Debug wurde nicht gefunden. Verfügbare Konfigurationen: "".
Stellen Sie sicher, dass der Wert der CMAKE_BUILD_TYPE-Variable derselbe wie der des "Build-Typ"-Felds ist.... cmake configuration Debug was not found. Ensure that the variable value CMAKE_BUILD_TYPE is the same as that of the Build Type area.
