Hi Nikos,

you said earlier you were able to use WX widgets. Did you do something in between that and your system now not being able to find the libgnuradio-wxgui library?

Hey all,

Just to start experimenting with GNU Radio and companion I just created a simple flowgraph consisting of a Signal Source Block and a WX GUI FFT Sink connected to it, to see if the diagram will be generated. I get a run-time error, namely:

Executing: "/home/nikos/top_block.py"

Traceback (most recent call last):
  File "/home/nikos/top_block.py", line 12, in <module>
    from gnuradio import wxgui

    from wxgui_swig import *
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/wxgui_swig.py", line 28, in <module>
    _wxgui_swig = swig_import_helper()
  File "/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/wxgui_swig.py", line 24, in swig_import_helper
    _mod = imp.load_module('_wxgui_swig', fp, pathname, description)
ImportError: libgnuradio-wxgui- cannot open shared object file: No such file or directory

What could be wrong here?

Thank you,
