Hi all,

after a fresh build of gnuradio on a gentoo 64 bit system the qtgui
stuff doesn’t work anymore.

Make test fails with. The output is:

qwt 6.0.2 and qt-4.8.4 are installed.

Any ideas ?

Thanks in advance

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.
