That is only a warning, the errors that the compiler finds are related to:
const QMetaObjectExtraData MasterHandler::staticMetaObjectExtraData = {
The odd thing is that the file moc_qt.cpp contains multiple definitions of this
member as well as the function qt_static_metacall. I cannot find a version
where the dllimport attribute is used.
I compared the code to the one generated by the regular build (the august one)
and they are identical apart from the file extension (.cpp versus .cxx) and the
timestamp.
This is really puzzling, I agree with your analysis that there should be no
difference between the two build methods.
Regards,
Arjen
