[Discuss-gnuradio] gnuradio + itpp error

[Alex Weihkopf]

Hello,

 

I am trying to use the ieee802.11 module by ccs labs (https://github.com/bastibl/gr-ieee802-11). I followed the installation instructions for itpp, but my flowgraph still fails.

 

The error message: 

 

Traceback (most recent call last):
  File "/home/*******/Desktop/top_block.py", line 15, in <module>
    import ieee802_11
  File "/usr/local/lib/python2.7/dist-packages/ieee802_11/__init__.py", line 37, in <module>
    from ieee802_11_swig import *
  File "/usr/local/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.py", line 26, in <module>
    _ieee802_11_swig = swig_import_helper()
  File "/usr/local/lib/python2.7/dist-packages/ieee802_11/ieee802_11_swig.py", line 22, in swig_import_helper
    _mod = imp.load_module('_ieee802_11_swig', fp, pathname, description)
ImportError: /usr/local/lib/libgnuradio-ieee802_11.so: undefined symbol: _ZN4itpp9ModulatorISt7complexIdEEC1Ev

 

In the last line Ican see that the problem is itpp, but I'm sure it's installed correctly (my flowgraph works on another computer where I followed the exact same instructions).

 

I am using Ubuntu 12.04 and Gnuradio 3.7.4.

 

Can anybody help me with an idea what to do?

 

Regards,

Alex
