Installiation issue with Qt Quick Components for Desktop to use with Qt Creator

[Craig27]

I have some installation issues with the Qt Quick Components for Desktop.

Any help to resolve the issue is appreciated.

Following are the steps I have followed

• Downloaded the tar.gz from http://qt.gitorious.org/qt-components/desktop/trees/master Unpacked the components

• Added path variable value to the environment variables (OS : Windows 7) C:\QtSDK\mingw\bin;C:\QtSDK\Desktop\Qt\4.8.1\mingw\bin

• Ran the following command: qmake && mingw-make install This command has automatically copied the compiled component files to C:\QtSDK\Desktop\Qt\4.8.1\mingw\imports\QtDesktop

Now when am going to the creator. In the design tab I can see the desktop components.
But its giving following error.

QML Module does not contain information about components in plug-ins

Module path : C:/QtSDK/Desktop/Qt/4.8.1/mingw/imports/QtDesktop
See "using QML Modules with Plugins' in documentation
....

'file:///C:/QtSDK/Desktop/Qt/4.8.1/mingw/imports/typelist.qml:2:1 module 'QtDesktop'plugin 'styleplugin' not found

Just ran into this and I think we had a similar issue recently:

We actually have the Qt Creator standalone install, but we needed to do the following:

• In addition to what you did in \mingw\imports, add the whole \QtDesktop contents to the Qt creator lib path, e.g. for me:
  C:\Qt\qtcreator-2.5.2\lib\qtcreator.
  Make sure this includes the plugin subfolder with the "styleplugin.dll" your make should have built.

E.g. my path to the styleplugin is:
"C:\Qt\qtcreator-2.5.2\lib\qtcreator\qtcomponents\plugin\styleplugin.dll"

(we called our folder 'qtcomponents', not 'QtDesktop', but this should not make the difference).

Hope this can be of some help.

Thanks mate,
I tried this but this is making Qt Creator crashing on loading :(

Sorry to hear that.

I think I am out of clue here, because we're on VStudio 2008 compilers, and I don't know the specifics maybe to take care of with gcc builds.

Actually I'm not sure what the "mingw-make install" target does, if it just copies files somewhere, or actually builds the "styleplugin" DLLs. But rest assured it took us while to have the stuff working:

In the end I think we did it like this:

• we rebuilt the styleplugin and styleplugind.dll DLL using qmake and nmake (VStudio make). The copied the QtDesktop files including the plugin to various locations.

In fact I see the QtDesktop stuff ending up at three different locations on my PC:

• C:\Qt\4.8.3\imports\QtDesktop

• styleplugin.dll and styleplugind.dll to
  C:\Qt\4.8.3\plugins\QtDesktop

• C:\Qt\qtcreator-2.5.2\lib\qtcreator\qtcomponents

But I'm honestly not 100% sure here and with no time to check. I can maybe ask my colleague to check again what in the end was the trouble.

Thanks Oliver, I'm also trying to troubleshoot the issue.
In case I found any breakthrough I will update you on the same
