Qt's version mixing.

[aliks-os]

I have updated my application from Qt5 to Qt6. The succesfully built it. But on running I get a message that Qt5Core.dll and Qt5Network.dll were not found.

In the .pro file, the core5compat is disabled.

Please advise, how locate what module, class, etc uses the Qt5 modules.

@aliks-os I would say you built your app using Qt5.
How exactly did you build?

[aliks-os]

@jsulm
In the QtCreator: clear, than rebuild

[jsulm]

@aliks-os said in Qt's version mixing.:

than rebuild

Using Qt6 Kit?

[aliks-os]

@jsulm sure

[jsulm]

@aliks-os When do you get this error? Where do you start the app?

[aliks-os]

@jsulm yes, when I start application from QtCreator

[jsulm]

@aliks-os Can you show the build log/compiler/linker output?

[aliks-os]

@jsulm Probably, I suppose the reason....the application uses third party dll, that it was built by Qt5, can it be a reason?

[aliks-os]

Yes, i confirm, that is a reason. Thanks for quick help
