ubuntu qt6.4.2 system install and qt6.7 online istaller conflict

gfxx

every project seems qt creator online installer is not configured for build home/qt project file but /usr/lib/x86_64-linux-gnu/cmake/Qt6xxxxxxx file ... so receive these error or similar one>

/home/gc81/Qt/Examples/Qt-6.7.3/graphs/3d/surfacegallery/CMakeLists.txt:22: warning: Found package configuration file:

  /usr/lib/x86_64-linux-gnu/cmake/Qt6/Qt6Config.cmake

but it set Qt6_FOUND to FALSE so package "Qt6" is considered to be NOT
FOUND.  Reason given by package:

Failed to find required Qt component "Quick3D".

Expected Config file at
"/usr/lib/x86_64-linux-gnu/cmake/Qt6Quick3D/Qt6Quick3DConfig.cmake" does
NOT exist

How can set qtcreator for use only home/qt dir instead /usr/lib/x86_64-linux-gnu/cmake/Qt6CoreTools one

@gfxx
At a guess check your Run configuration for the project and see what it has for the executable to produce? Maybe it got cleared when you changed compilers?

Christian Ehrlicher

Use the correct kit in QtCreator which points to your 6.7.3 installation.

@Christian-Ehrlicher actually I use qtcreator 14 .... on ubuntu 24, and remove qtcreator of ubuntu repository (qtcreator 13) ... So I can use only what receive from online-isntaller .... but if try to compile an example project I obtain these situation ....

That is not desired ..... all module need to be find on /home/gc81/Qt/....... need to move manually everytime from /usr/lib .... to /home/... ??? Or there are possibility to make these automatic?

I change qmake kit to only one qt6.7.3 present on pc ... but these not help to change DIR module folder in qt creator.

DIR_NOTFOUD .... because not discover the module on system ... that have qt6.4.2 installed.

Christian Ehrlicher

I don't see what your Qt installation has to do with what QtCreator you're using.
When you've installed Qt6.7 somewhere then normally QtCreator correctly creates a kit for it. If not, you have to do it by your own: https://doc.qt.io/qtcreator/creator-targets.html

@Christian-Ehrlicher these is my kit

as you see is the default one ....

gfxx

@Christian-Ehrlicher .... after restart the pc ... all become normal .... BUT webchannel reply to me that not possible use CLANG ... so I switch to GCC .... and now receive these messages:

:-1: error: You need to set an executable in the custom run configuration.

what means? ..... I reply by me:

That project for some reasons have not cmake file, but .pro file incomplete .... maybe need to clean it .... other example work as expected.

@JonB just done .... and it works ...but now try a webengine project and receive these messages:

/home/gc81/Qt/Examples/Qt-6.7.3/webenginewidgets/recipebrowser/CMakeLists.txt:16: warning: Found package configuration file:

  /home/gc81/Qt/6.7.3/gcc_64/lib/cmake/Qt6WebEngineWidgets/Qt6WebEngineWidgetsConfig.cmake

but it set Qt6WebEngineWidgets_FOUND to FALSE so package
"Qt6WebEngineWidgets" is considered to be NOT FOUND.  Reason given by
package:

Qt6WebEngineWidgets could not be found because dependency Qt6PrintSupport
could not be found.

Configuring with --debug-find-pkg=Qt6PrintSupport might reveal details why
the package was not found.

Configuring with -DQT_DEBUG_FIND_PACKAGE=ON will print the values of some
of the path variables that find_package uses to try and find the package.

Call stack:
  /home/gc81/Qt/Examples/Qt-6.7.3/webenginewidgets/recipebrowser/CMakeLists.txt:16 (find_package)
  /home/gc81/Qt/6.7.3/gcc_64/lib/cmake/Qt6/Qt6Config.cmake:169 (find_package)

but print support there is I think on QT6.7.3 folder .... so not understand .... well

really I try to clean and re-install 6.7.3 ..... so cancel previous build of example .... I set immediately gcc as compiler and try ... all works ... you are in right. Thanks
