I tried the code of 'Tutorial - Using the QT GUI Blocks in GNU Radio', but
error occurred.
Traceback (most recent call last):
File "qt_basics.py", line 4, in <module>
from gnuradio.qtgui import qtgui
File
"/opt/gnuradio/3.3.0/lib/python2.6/site-packages/gnuradio/qtgui/qtgui.py", line
6, in <module>
import _qtgui
ImportError: /opt/gnuradio/3.3.0/lib/libgnuradio-qtgui-3.3.0.so.0: undefined
symbol: _ZN9QwtPicker5resetEv
Who can tell me what is the problem? Thank you!
