Then the corresponding plugin library libQVTKWidgetPlugin.so was copied
into the plugin directory of QtCreator. However, the QVTKWidet won't
appear in the widget list when I open the UI editor window of QtCreator.
I obtained a libQVTKWidgetPlugin.so file from Trolltech Qt support
persons who also installed VTK 7.7.1 with the same comfiguration
options. I copied this file into plugin directory of Qtcreator and I
could see the QVTKWidger in the widget list of the UI editor window of
Then I checked the objects in both the plugin library files with objdump
and I found that the qt_pluginMetaData and qt_plugin_instance symbols
are missing from my libQVTKWidgetPlugin.so, whereas they can be found in
the plugin library file obtained from Trolltech. Both should be coming
through a file that is generated by moc. I have no idea why these
wouldn't be there. Has any one an idea what went wrong with the
compilation of VTK 7.1.1 in my desktop? Thank you very much!
