How to use [windeployqt.exe] ?

[Knj.Tkm]

Hi.
I want to Deployment for Windows.
I use windeployqt.exe, but I get error.

Error String is:
[the procedure entry point ?cacheKey@QPixmap@@QEBA_JXZ could not be located in the dynamic link library C:\Qt\5.14.2\msvc2017_64\bin\Qt5WinExtras.dll ]

I use MinGW and Qt 5.15.2.
Why I get this error?

Then maybe you have path to MSVC Qt in your $PATH?

HOW do you use windeployqt? Please post full command line.

It's quite clear from the output that it is trying to deploy MSVC but you say you are using MinGW - these two are not compatible. Make sure you use windeployqt from correct Qt installation.

I use Command
[ windeployqt.exe --qmldir ../../qml ./ ]

My app path
C:/MyApp/build/debug/(Application)

qml folder is in MyApp

windeployqt.exe

Then make sure you take windeployqt.exe from your MinGW Qt installation, and not from MSVC.

Also, make sure to clean the directory before attempting it anew, IIRC the tool will not overwrite existing files

I'm definitely using the correct windeployqt.exe from MinGW.
But I get the error again.

Yes, I try after cleaning every time.

Oh, That's Right!
I forgot to set system environment variable.
Thank you for Answer!
