Deployment

[jrod2much]

Alright, so I did all the steps. For some reason, Release is crashing so I did it using Debug. The executable runs on my computer but when I try to run it on another computer, nothing happens. Any idea on what's wrong?

@jrod2much use this tool dependency walker on your executable and maybe supporting libraries if any to see what other libraries (i.e. .dll files) are needed that maybe the windeployqt tool is unable to catch.

[jrod2much]

I used Dependency walker and its seems like I have all the .dll files. But also it is showing a whole bunch of question marks.

@jrod2much do you use QML in your project? If yes did you tell the deployment tool where to find your qml files, so that it can copy your QML-dependencies ?

[jrod2much]

@J-Hilk No QML in my project

it is very weird because the .exe file created using windeployqt works perfectly fine on my computer but if I transfer the entire folder to another computer, the .exe is unresponsive.

[jrod2much]

@J-Hilk @Pablo-J-Rogina now I am getting this error

Hi
And you did make/have a deployment folder with the right sub folders for it ?
it should look like ( as minimum. it can have mroe subfolders)

One suggestion would be to compile Qt from source with the option '-no-icu'. If you look at the above file list the three ICU files are over 28 mb in size where everything else combined is around 18 mb (including the platform DLL's). I think you only need the ICU files for webkit (?).

Hi, even though you have copied all files/folders correctly to the other PC, it could be another installation of Qt on it that disturbs your Pixymon.exe from loading its plugins.
You could try tracing the loading of plugins:
first download DebugView and start it to see the output,
then launch a CMD window and type:

SET QT_DEBUG_PLUGINS=1

then start Pixymon.exe from that CMD window and look at the messages appearing in DebugView, should be something like: “QFactoryLoader::QFactoryLoader() checking..."

@Rondog I'm not sure compiling Qt is the right suggestion for somebody having problems deploying a Qt app just to save some space...

@jrod2much
did you by chance use the wrong deployment tool ? each precompiled version of qt that you install comes with it's own tool. ANd if you compile your project with mingw and use the msvc windeploytool. The needed files are copied, but they are technically from the wrong Qt-Folder.

so as usual, i just kept trying things and it finally worked haha, Thank you guys. I don't think it was a Qt problem but more of an individual program problem having to do with missing files.
