yes, I find those.
e.g. qt_version_tag_WinCC_OA_5

It is failing when building qtdeclarative/tools/qml

It seems QtGui is referring to the symbol:
/home/PACKAGES/qt/qt-repo/qt5/qtbase/lib/libQt5GuiWinCC_OA.so: undefined reference to `qt_version_tag'

so I checked in the gui Makefile and find something I do not understand:

DEFINES       = -DQT_NO_USING_NAMESPACE -DQT_ENABLE_HARFBUZZ_NG -DENABLE_PIXMAN_DRAWHELPERS -DQT_BUILD_GUI_LIB -DQT_BUILDING_QT -DQT_NO_CAST_TO_ASCII -DQT_ASCII_CAST_WARNINGS -DQT_MOC_COMPAT -DQT_USE_QSTRINGBUILDER -DQT_DEPRECATED_WARNINGS -DQT_DISABLE_DEPRECATED_BEFORE=0x050000 -DQT_NO_EXCEPTIONS -D_LARGEFILE64_SOURCE -D_LARGEFILE_SOURCE -DQT_CORE_LIB -DQT_NAMESPACE=WinCC_OA

Why does it use -DQT_NO_USING_NAMESPACE _and_ -DQT_NAMESPACE=WinCC_OA ?
