Hi,

I made

   http://bugreports.qt.nokia.com/browse/QTMOBILITY-493

<http://bugreports.qt.nokia.com/browse/QTMOBILITY-493>Short-term you can work around the issue by building release or debug only.

Cheers,
Henrik

Hi,

I have rebuild qt, mobility from scratch to be sure ... And I have the same issue.
I have checked with depends my executable and the library : it's ok ...debug version use debug lib, and release version use release lib ...

I have find that you build qt-mobility, debug version of declarative plugin are not build with d suffix ... so the dll for debug and release have the same name ... If you look in qt/imports/multimedia (the same for all declarative mobility plugins) folder there is the release dll plugin and a pdb with no ...d and there is no ...d.dll ... It seems first debug version with no suffix d is copied and overwritten after by release dll...

I need to manually copy file debug (renaming with d.dll) from plugins/declarative  to imports/qt/multimedia.

then after I have another trouble : I have created a small pure qml exemple (no c++) with qmlviewer :

@
import Qt 4.7

import Qt.multimedia 1.1

Rectangle {

    width: 200

    height: 200



    Video {

   id: video

   anchors.fill: parent

   source: Qt.resolvedUrl("C:/TestFolder//test.wmv")

   Component.onCompleted : video.play();

   }

}

@

I if launch qmlviewer have the following warning in qml viewer warning window :

QMediaPluginLoader: Failed to load plugin: "C:/QtMobility/plugins/mediaservice/dsengine.dll" "The plugin 'C:/QtMobility/plugins/mediaservice/dsengine.dll' uses incompatible Qt library. Expected build key "Windows msvc debug full-config", got "Windows msvc release full-config""

QMediaPluginLoader: Failed to load plugin: "C:/QtMobility/plugins/mediaservice/qtmedia_audioengine.dll" "The plugin 'C:/QtMobility/plugins/mediaservice/qtmedia_audioengine.dll' uses incompatible Qt library. Expected build key "Windows msvc debug full-config", got "Windows msvc release full-config""
QMediaPluginLoader: Failed to load plugin: "C:/QtMobility/plugins/mediaservice/qtmedia_wmp.dll" "The plugin 'C:/QtMobility/plugins/mediaservice/qtmedia_wmp.dll' uses incompatible Qt library. Expected build key "Windows msvc debug full-config", got "Windows msvc release full-config""

If I try for  example : declarative-mapviewer demo : i need to rename declarative location plugin with the d.dll and copy to the /imports/mobility/... and then it works without trouble.

I don't know  if it helps ... :)

Do you get the same issue for the demos and examples in the mobility repo? Can you verify the dependencies on your exe and dll's with depends.exe?

Cheers,
