I have this very strange problem while compiling the project. MOC seems to be adding a namespace to the class name being moc'ed, although it's not mentioned anywhere in the file/class.
The namespace, however, exists in a library which I use, but it's hidden far away in the header files and I don't use it in the UI files. This is what MOC generates:
const QMetaObject SmpTl::CaptureController::staticMetaObject = {
{ &QObject::staticMetaObject, qt_meta_stringdata_SmpTl__CaptureController,
qt_meta_data_SmpTl__CaptureController, 0 }};
The SmpTl namespace is not mentioned anywhere in the declaration of CaptureController, but it appears in the MOC-generated .cpp file.
I'm using Visual Studio with the QT integration.
