Hello,
New machine with new Kubuntu 15 install, new build-gnuradio install on that system.
Had some install issues with a prereq lib that required a force-overwrite to a deb archive. But seemed to progress normally after that was fixed. Also had a warning regarding a missing libzmqt(?) dev package which seems to be something build-gnuradio does under (k)ubuntu 15. But everything built, and afterwards I was also able to build and install my OOT stuff without anything unusual.
But when I attempt to actually run any of my flowgraphs in GRC I get the following crash (back to GRC) message:
Traceback (most recent call last):
File "/home/jmurphy/MyGNUradioFiles/multi_file_playback.py", line 23, in <module>

ImportError: /usr/local/lib/libgnuradio-qtgui-3.7.7.1.so.0.0.0: undefined symbol: _ZNK7QwtPlot5printEP8QPainterRK5QRectRK18QwtPlotPrintFilter
Any idea what I might need to do in order to get this working? Steps to troubleshoot further?
Thanks,
John
