[SOLVED] QML module plugin load fail after upgrade to Qt 5.4.0

  • Good day,

    I have an existing QML module plugin that works 100% with my Qt 5.3.2 installation. However, I recently installed Qt 5.4.0 and suddenly the qmlplugindump fails with:

    @QML module does not contain information about components contained in plugins.

    Module path: C:/PluginTest/QtQmlComponents/QmlComponents
    See "Using QML Modules with Plugins" in the documentation.

    Automatic type dump of QML module failed.
    "C:\Qt\Qt5.4.0\5.4\msvc2013\bin\qmlplugindump.exe" returned exit code 3.
    Arguments: -nonrelocatable QmlComponents 1.0 C:/PluginTest/QtQmlComponents
    QQmlComponent: Component is not ready
    file:///C:/PluginTest/QtQmlComponents/typelist.qml:2:1: module "QmlComponents" plugin "QtQmlComponents" not found@

    What irks me is that I cannot figure out why it no longer works. I have recreated my actual project directory structure to the best of my ability, which is available "here" EDIT: Removed Link

    If you copy the "PluginTest" directory to your C:\ drive, it should be a simple "plug and play" to test.

    I'm using QtCreator 3.3.0 (bundled with Qt 5.4.0) on Windows 7, 64-bit.

    Any advice will be appreciated.


  • I have the following in my .pro file (for the plugin):

    @TEMPLATE = lib
    TARGET = QtQmlComponents
    QT += qml quick
    CONFIG += qt plugin

    TARGET = $$qtLibraryTarget($$TARGET)@

    For Qt 5.3.2, the output dll's are named: "QtQmlComponents" as per the component target.

    For Qt 5.4.0, the output dll's are named "Qt5QmlComponents", which breaks everything.

    EDIT: It only affects me because I'm using "Qt" as part of my plugin name.
