Still trying to Deploy... using windeployqt.exe

[ODБOï]

@webzoid Thx,I haven't thought about Windows Event Viewer.. , I will check then give you a feedback tomorrow.

@LeLev Which "2 or 3" dll's are missing then? are they always the same one or is a random thing?
how do you run windeployqt and how do your build paths look in relation to it when you run it?
As @LeLev says you may need to copy MVC runtime dll and any other stuff that windeployqt does not now about.

If I understand correctly, when you run the app on windows no error message or no UI comes. It means that your application is running and UI does not come up. Most probably Qt 'platforms' plugins could be missing in the new box. Just ensure that your copy these platforms plugin directory also.

Thank you for answers

@webzoid unfortunately nothing interesting in Windows Event Viewer.

@kenchan So with windeployqt.exe i had :

bearer / iconengines / imageformats platforminputcontexts / platforms / qmltooling / styles / translations
D3Dcompiler_47.dll / libEGL.dll / libgcc_s_dw2-1.dll / libGLESV2.dll / libstdc++-6.dll / libwinpthread-1.dll / opengl32sw.dll /Qt5Core.dll / Qt5Gui.dll / Qt5Network.dll / Qt5Qml.dll / Qt5Quick.dll / Qt5Svg.dll / Qt5Widgets.dll / myApp.exe

With this my application was not running (and no error message ) even on my developpement pc

I sorted, now i have :
bearer / iconengines / imageformats platforminputcontexts / platforms / qmltooling / styles / translations
libstdc++-6.dll / Qt5Core.dll / Qt5Gui.dll / Qt5Network.dll / Qt5Quick.dll / Qt5QuickControls2.dll /Qt5QuickTemplates2.dll / myApp.exe

and now my app starts correctly, but only on my dev pc

As i said application is not visible in Process Explorer, so is it possible ?
and inside platforms there are : qwindows.dll/qwebgl.dll/qoffscreen.dll/qminimal.dll

Thx

@LeLev have you tried running procmon with your app? it might give you a clue as what it is doing an when it dies.

@kenchan THX.
There are more than 1000 operations about my application when i run procmon and then try to run my app.

Most of time result is SUCCESS

But i have this :
OPERATION : CreateFile
PATH :C:\Users\lev\Desktop\winDep\QtQuick.2.8
RESULT: NAME NOT FOUND Desired Access: Read
OPERATION :CreateFile
PATH : C:\Users\lev\Desktop\winDep\qml\QtQuick.2.8
RESULT : PATH NOT FOUND Desired Access: Read Attributes
OPERATION: CreateFile
PATH : C:\Users\lev\Desktop\winDep\QtQuick.2 NAME NOT FOUND Desired Access: Read Attributes,
OPERATION: CreateFile
PATH : C:\Users\lev\Desktop\winDep\QtQuick\Window.2.2 PATH NOT FOUND

I have PATH NOT FOUND on every Qt module and even my Classes

in my code i have

qmlRegisterType<ClientCN16K>("com.Meca.ua.cn16k",1,0,"MecaUAClient");
qmlRegisterType<Machine>("com.Meca.ua.cn16k",1,0,"Machine");

and procmon says :

OPERATION : CreateFile
PATH: C:\Users\lev\Desktop\winDep\com\Meca\ua\cn16k.1.0
RESULT : PATH NOT FOUND Desired Access: Read Attributes, Disposition: Open, Options: Open Reparse Point, Attributes: n/a, ShareMode: Read, Write, Delete, AllocationSize: n/a

...

@LeLev I don't understand what all that refers to, but as long it gives you a clue :-)
I have found procmon to be useful for things like this.

To add my 2 cent,

Recently I had some issues with windeployqt turned out, that all needed files were copied, but from the wrong directory.

I ended up replacing all files and folders manualy, than the application worked.

[mrdebug]

windeployqt helps but it isn't a solution.
You should use qt.conf to setup where the qt app should search the plugins.
If you need a plugin that requires a specia qt dll, windeployqt can't help you. If you are using qml, the qml subfolder has to be added manually.
Please have a look at my qt apps, just to have an idea on how I share it.
http://www.denisgottardello.it/QtComPort/index.php
I normally add all the dlls and the plugins to prevent problems.

Thx @mrdebug ! i just addes qml subfolder + qt.conf file
http://www.tripleboot.org/?p=536 //nice article Here
//qt.conf
[Paths]
Plugins=plugins

Now its workink perfectly!

Thank you very much everybody !

[SGaist]

Hi,

Out of curiosity, which version of Qt and windeployqt are you using ?

[ODБOï]

@SGaist hello,
Im using Qt 5.10.0 MinGW32bit2
windeployqt 5.10.0.0

Can someone tell me how to add 'Line number information' to get it in procmon please ?

Thanks

@LeLev
FYI, I found this tool quite useful when I first tried windeployqt:
https://github.com/lucasg/Dependencies
This is a modern, open source version of the now obsolete Dependency Walker.

Just open your .exe file (the one in your deployment folder) in it.

It showed that I forgot to copy my fftw dlls to my deployment folder... and shows the other system dll's it requires.

[ODБOï]

@Diracsbracket Thx. I will check that tool.
