Hi Volker,
I'm guessing that you are using the master branch from the name of your
library? (not that that changes too much).
This strikes me as an issue with a library linking problem. I'd recommend
deleting your CMakeCache.txt file in your build directory, rerun cmake, and
then rebuild (might even want to 'make clean' in gr-qtgui). QwtScaleMap
definitely exists in Qwt 6.0.2, and I'm using it right now. I think
something just got confused in a version change somewhere.
Tom
