The Qt Serial Port module also supports Qt4 - see note on http://wiki.qt.io/Qt_Serial_Port In a current Qt4 project we needed this module so I wrote an ebuild - attached. Please consider adding it. Reproducible: Always
Created attachment 505882 [details] Ebuild for Qt4
It is unlikely there are going to be any additions to Qt4 packages at this point, while we are busy weeding out Qt4 dependencies everywhere.
OK. At least the ebuild is documented here and hopefully findable with Google for anyone needing it.
Sorry, we're removing Qt 4 support in the tree and not adding anything new.
