Running a QML .exe file on Windows

tomy

Hi,

Using Qt 5.10 on Qt Creator I ran a QML program by the Desktop kit in the Release mode. Then I copied its executable file into a folder and added all .dll files it requested for being run from this address:
C:\Qt\Qt5.10.0\5.10.0\mingw53_32\bin

Now when I double click the file it makes no action!
What can the problem be please?

Hi,

Take a look at windeployqt especially the qmldir option for deploying applications for Windows.

Take a look at windeployqt especially the qmldir option

It's a executable file in the address:

C:\Qt\Qt5.10.0\5.10.0\mingw53_32\bin

When I double click it, it has no reaction just a quick blink.
If there is an appropriate method to make that "my_file" file run properly, please tell me of that.

SGaist

It's a command line tool.

Here are the files with that name on my PC:

Which one do you mean? And how to use its options especially qmldir please?

VRonin

click start
type cmd press enter.
A black console opens
type "C:\Qt\Qt5.10.0\5.10.0\mingw53_32\bin\windeployqt.exe"
read the help on what to pass as arguments
call windeployqt again with the appropriate arguments

Hi,

I used this command. Is it correct please?

C:\Qt\Qt5.10.0\5.10.0\mingw53_32\bin\windeployqt.exe --qmldir C:\Users\Abbasi\Desktop\Test\QML_test.apk C:\Users\Abbasi\Desktop\data\QML_test.exe

You have to give the path to where your QML files are in your application sources to the --qmldir option.

@SGaist

You have to give the path to where your QML files are in your application sources

Which folder do you mean from the following ones? I used the second one from top.

SGaist

As I already wrote: your application sources where the qml files are located.

Have you solved this problem?I encountered the same problem,my enviroment is msvc2017_64 + win10.

jsulm

@Crawl.W Did you use windeployqt tool?

Crawl.W

@jsulm Yes,windeployqt can not deploy a executable application，I double click the exe but nothing ever happens.I answer the question on stackoverflow.com where user name is Crawl.W as here.I copy qml floder to runtime directory,and then run the exe, then fell all other unoccupied files heartily.But seemly cannot delete some unoccupied thing in qml\QtQuick, if I delete it double click the exe will have nothing happened.

@Crawl.W
You must pass it the correct arguments not just double click the exe.
did you look at he docs here

Crawl.W

@kenchan My program haven't arguments need to pass. I will read your post linkage carefully and refine some answers here.

@Crawl.W
Kenchan has mentioded the deploy tool arguments.

Windeployqt does'nt know if you are deploying an qml application, so you need to pass --qmldir [your qml root path folder] argument

Note: if your qml root path folder has space characters, you should use double quotes between your path or it will interpret as Different Commands.

@KillerSmath @kenchan I found my posting linkage of stackoverflow is invalid, I update it just now, Here(https://stackoverflow.com/questions/44762836/deploying-qt-c-qml-application-on-windows/55850012#55850012). My problem seems to need some non-dynamic library(DLL), and runtime is unoccupied. Kind of weird. I had already run my program and then I wanna know that's about what.

KillerSmath

@Crawl.W
If your apllication is running on test environment, so the windeployqt should able to identify and copy the dependent dlls.
Keep in mind, you also can use --force parameter to copy the dependencies even though they already exist on deploy folder.

Crawl.W

@KillerSmath I have tried --qmldir [your qml root path folder], deployed program is still not work.

KillerSmath

@Crawl.W
Can you show a detailed command example ?
