.exe file is not opening

[J.Hilk]

@Vijaykarthikeyan are you using QML in your project ?

[Vijaykarthikeyan]

@J-Hilk yes.. QML for front end design..

C++ for backend processing

[J.Hilk]

@Vijaykarthikeyan than you're most certainly missing the QML part during windeployqt call:

--qmldir <directory>

with <directory> being the full path to your main QML folder, as in where your main.qml is

otherwise how should the tool know what from QML you used in your application

[Vijaykarthikeyan]

@J-Hilk Are you mentioning about this directory,

"qrc:/resources/main.qml"

I don't want to mention any specific directory because I want to deploy in various target systems. That's why I preferred this one over local directory

[J.Hilk]

@Vijaykarthikeyan you misunderstand, the windeployqt tool needs to know where your own qml files are so it can parse them, and according to the imports used, copy the needed dlls/modules over.

if you don't specify your qml folder via --qmldir that part of the deployment will be missing.

the tool will NOT copy any of your QML files over

[Vijaykarthikeyan]

@J-Hilk Somewhat understandable.. but still confused.. I understand that i have to include --qmldir <path/to/qml>

Can you show me some minimal example..please,sir

[jsulm]

@Vijaykarthikeyan Not sure what example you need?
You simply add one additional parameter to windeployqt as explained in the documentation (https://doc.qt.io/qt-6/windows-deployment.html):
"--qmldir <directory> Scan for QML-imports starting from directory."

@jsulm I'm succesfully executed that command line : windeployqt --qmldir <path to qml directory in qt version> <bin_file>.exe..

it is successfully scanned without any error:

Updating tr.pak.
Updating uk.pak.
Updating vi.pak.
Updating zh-CN.pak.
Updating zh-TW.pak.

C:\Users\hp\build-incline2-Desktop_Qt_5_15_2_MSVC2019_64bit-Release\release>

but,then i try to run the.exe file,it is again not running

[jsulm]

@Vijaykarthikeyan said in .exe file is not opening:

it is again not running

Same issue? Something else?

[Vijaykarthikeyan]

@jsulm same issue.

after running the command in corresponding directory like: windeployqt.exe --qmldir <path/to/qml library> <file_name.exe> ..it is scanned and updated allthe required libraries

when running that project's .exe file.,it is showing showMaximized,widgets.dll,webengine.dll,qt5core.dll,webenignecore.dll is not located in dll

all the requires libraries are updated but it shows error like this:

Is that any wrong with my command?

@Vijaykarthikeyan said in .exe file is not opening:

windeployqt.exe --qmldir <path/to/qml library> <file_name.exe> --compiler-runtime

If you use Qt6 you need to use windeployqt6.exe instead of windeployqt.exe and you need to add --compiler-runtime to copy the missing compiler files

To sum it all up, I usually create a folder were I copy only the executable file, cd in to that folder and run the windeployqt6 from there:

cd D:\qtprojets\MyAppDeployFolder

C:\QtOpensourse\6.5.0\mingw_64\bin\windeployqt6.exe --qmldir D:\qtprojets\MyApp D:\qtprojets\MyAppDeployFolder\MyApp.exe --compiler-runtime

If you have several Qt versions, you should use the same windeployqt6.exe version of the compiled exe file

[Vijaykarthikeyan]

@johngod I'm using 5.15.2

[johngod]

@Vijaykarthikeyan Did it work ? If so, please mark the this as solved.

[Vijaykarthikeyan]

@johngod I'm using 5.15.2 version. I've added --no-compiler-runtime at the end..

My command is like this one: C:\Qt\5.15.2\msvc2019_64\bin>windeployqt.exe --qmldir C:\Users\hp\build-incline2-Desktop_Qt_5_15_2_MSVC2019_64bit-Release\exe --no-compiler-runtime

the bit versions are correct and correct directory..

but it is not importing any libraries in that exe folder..still get 4 error messages..Please help me to sort it out.

[jsulm]

@Vijaykarthikeyan said in .exe file is not opening:

--qmldir

This should point to your QML files in the project folder, not in build folder as far as I know. And you're also missing path to the exe file when calling windeployqt.exe.

[Vijaykarthikeyan]

@jsulm Thank you so much.. Your guidance solved my long term problem. I'm trying to search the solution for last two months. At last, that .exe file s running.. Thank you once again.. thank you too @johngod .. I owe you both

[Vijaykarthikeyan]

@johngod Yes,it is working..you have solved my 2 months problem..thank you soooo much

[Vijaykarthikeyan]

@jsulm So, the correct template should be look like this:

<qt-binary-folder>windeployqt.exe --qmldir <path-to-project-file> <path-to-Qt-build-folder>

[Vijaykarthikeyan]

@J-Hilk Thank you
