Problem using gr-doa / Qt / Ubuntu 18.04

[Alexandru Martian]

Hello all,

I was trying to setup the gr-doa for performing DoA measurements using USRP X310 equipped with two TwinRX RF daughterboards and I encountered the following error while trying to run the view_X310_TwinRX_op_with_corrected_phase_offsets, after installing the qt4 and qwt5 packages (the operating system is Ubuntu 18.04, UHD 3.10.3):

Traceback (most recent call last):
  File "/home/alexandru/Downloads/gr-doa/apps/view_X310_TwinRX_op_with_corrected_phase_offsets.py", line 30, in <module>
    import doa
  File "/usr/local/lib/python2.7/dist-packages/doa/__init__.py", line 37, in <module>
    from compass import compass
  File "/usr/local/lib/python2.7/dist-packages/doa/compass.py", line 30, in <module>
    import PyQt4.Qwt5 as Qwt
  File "/usr/lib/python2.7/dist-packages/PyQt4/Qwt5/__init__.py", line 32, in <module>
    from Qwt import *
RuntimeError: the PyQt4.QtCore module failed to register with the sip module

Could you suggest a possible solution? Thanks in advance!

Best regards,

Alexandru
