"qt_version_tag" is the name of the tag for unnamespaced Qt. If you do 
	readelf -s libQt5CoreWinCC_OA.so.5

You'll probably see "qt_version_tag_X" where X is your namespace, some with 
extra suffixes for previous Qt versions and one with @@. Can you confirm that?

Can you check if the build of this application had QT_NAMESPACE defined? Please 
paste the command-line that was used to compile main.cpp.
