@SPlatten said in windeployqt, looks ok, but no files transferred:

ok, just done exactly that the entire tree structure is now present, still getting exactly the same result.

If plugin is present, then there are dll which cannot be loaded.
Try to set QT_DEBUG_PLUGINS and take a look at debug messages on console when starting the binary.
I would recommend to use a little batch script to start the binary and redirect output to text file:

set QT_DEBUG_PLUGINS=1
trnServer.eve > debug.txt 2>&1

@SPlatten The directory structure is explained here: https://doc.qt.io/qt-5/windows-deployment.html

This is your problem

SPlatten

@jsulm , I'm 99% sure the exe I am using is from the release build as its only 923KB, the debug version of the same is 1,637 KB.

jsulm

@SPlatten said in windeployqt, looks ok, but no files transferred:

is from the release build

Then don't copy debug versions of the Qt libs/plug-ins, only release versions...

SPlatten

@jsulm , I haven't got any debug libraries ending with d.dll in the structure, confirmed this by using explorer with *d.dll in search platforms area.

jsulm

@SPlatten said in windeployqt, looks ok, but no files transferred:

QFactoryLoader::QFactoryLoader() looking at "C:/Users/simon.platten/Trainer/platforms/qwindowsd.dll"

Then what is this?

SPlatten

@jsulm , I really don't know how they got they're, perhaps on the last copy added from @KroMignon instruction? In anycase both the debug and the release dll's are in the same location, I will get rid of the debug dlls now.

Yes, copy with 'brute force' is not a kind way: perhaps you should add del %INSTFLDR%/*/*d.dll /a /s to remove the debug DLL.

But I see another problem:

Cannot load library C:\Qt\Qt5.9.2\5.9.2\msvc2015\plugins\platforms\qwindows.dll: Unknown error 0x000000c1.

Why do your application try to load plugins from C:\Qt\Qt5.9.2\5.9.2\msvc2015\plugins ?
Do you have set QT_PLUGIN_PATH?

SPlatten

@KroMignon , I don't have the QT_PLUGIN_PATH environment variable set, I'll try adding now.

Same, no difference.

KroMignon

@SPlatten said in windeployqt, looks ok, but no files transferred:

I don't have the QT_PLUGIN_PATH environment variable set, I'll try adding now.

Using QT_PLUGIN_PATH is not really necessary and don't made sense to me (cf. https://doc.qt.io/qt-5/deployment-plugins.html).

But why do your application try to load plugins from C:\Qt\Qt5.9.2\5.9.2\msvc2015\plugins and not from the application path?

Per default, the Qt application will try to load the plugin located in the application installation directory.
The only way to load from another location is:

set QT_PLUGIN_PATH
by using qt.conf (cf. https://doc.qt.io/qt-5/qt-conf.html)
set by code the plugin load path with QCoreApplication::setLibraryPaths()

What is your scenario?

SPlatten

@KroMignon , I am constructing or trying to build an installer since I cannot get it working. On the target system Qt will not have been installed and shouldn't need installing, so I am trying to package up everything required to run the executable, thats why the plugins are being installed relative to the EXE.

I understand this but, according to the console output, the application tries to load plugins from C:\Qt\Qt5.9.2\5.9.2\msvc2015\plugins:

QFactoryLoader::QFactoryLoader() checking directory path "C:/Qt/Qt5.9.2/5.9.2/msvc2015/plugins/platforms"

and not from the application path.

So my question is why? This is not the normal case, you must have done something special.

SPlatten

@KroMignon , why is because I didn't realise it would do this, I thought the default search criteria for DLL's is first to look in the local folder then to search the Windows folder, I don't know how or why its looking in the Qt installation folder?

SPlatten

@KroMignon Where does the qt.conf file go? In the same location as the EXE ?

NVM, read from documentation.

The way Qt is searching plugins is well documented (cf. https://doc.qt.io/qt-5/deployment-plugins.html).
This is why I asked you what you have done:

set QT_PLUGIN_PATH ?
defining a qt.conf file (cf. https://doc.qt.io/qt-5/qt-conf.html)?
by code with QCoreApplication::setLibraryPaths() or QCoreApplication::addLibraryPath()?

SPlatten

@KroMignon , I've created local qt.conf:

[Paths]
Plugins=.

This seems to have done the trick as the debug.txt reports the correct location is now being searched:

I've checked the that qwindows.dll is present, why can't it load the library?

It looks like this error relates to the EXE architecture being not compatible, the EXE is win32. I thought I had transferred the correct DLL's for win32, will check again.

Checked again, dll is the win32 version but still getting this message in the debug.txt ???

There is something very strange on your configuration.
Are you sure you are using same Qt-Kit as kit used to build the binary?
Can you run the binary with Qt Creator in release mode?

SPlatten

@KroMignon , thats the odd thing...I can't even run it though Qt Creator in release mode, the only difference is that the message appears in a dialog...debug works fine.
