[Discuss-gnuradio] Error: undefined symbol: volk_malloc

[Hoang Ngo-Khac]

Dear all,

I had gnuradio-3.7.3 running normally. However, now everytime I run a flowgraph in GRC, it stops and throws an error: 

Traceback (most recent call last):

  File "/home/khachoang/GNU_Radio/test_grc/2Node_NoController/top_block.py", line 14, in <module>

    from gnuradio.filter import firdes

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/filter/__init__.py", line 32, in <module>

    from filter_swig import *

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/filter/filter_swig.py", line 28, in <module>

    _filter_swig = swig_import_helper()

  File "/usr/local/lib/python2.7/dist-packages/gnuradio/filter/filter_swig.py", line 24, in swig_import_helper

    _mod = imp.load_module('_filter_swig', fp, pathname, description)

ImportError: /usr/local/lib/libgnuradio-filter-3.7.3.so.0.0.0: undefined symbol: volk_malloc

I haven't seen it before and have no idea why. Before it become like that, I ran this command: apt-cache search libqt4.

How should I fix it?

Thanks,

Hoang Ngo
