Hello,
I cannot answer Your question directly as I have encountered similar
errors with gr-doa. Due to qt-gui compass plugin and some other
dependencies when I tried to run it with USRP B210. Unfortunately, it is
no longer maintained or updated. (I never got this qt-compass to work).
What I can suggest is a more up to date version of gr-doa, which is:
https://github.com/MarcinWachowiak/GNU-Radio-USRP-AoA
<https://github.com/MarcinWachowiak/GNU-Radio-USRP-AoA>
(it is based on gr-doa with some modifications, fixes and additional
blocks, ported from Armadillo to Eigen which is faster)
Whole repository is for GR 3.8.2 and there are some example flowgraphs
showing the default configuration.
The repository lacks QT gui compass, but there are some other blocks or
routines instead. There is dynamic method of synchronization of the
channels using sample and hold block instead of reading from file.
Although the examples are for 2 channels the flowgraphs can be easily
extended for a case with more input signals.
Wish You best the best of luck with DoA.
Kind regards,
Marcin Wachowiak

Temat: Problem using gr-doa / Qt / Ubuntu 18.04
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 "/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
