    run time error

    using ubuntu 12.10 i am trying to run a python block, namely OP25, in GNU Radio Companion v3.6.3-35-g4435082f. i get the following error:

    Code:
    Executing: "/home/matt/op25_grc.py"
    
    Imported legacy fsk4
    Using Volk machine: ssse3_32
    Traceback (most recent call last):
      File "/home/matt/op25_grc.py", line 493, in <module>
        tb = op25_grc()
      File "/home/matt/op25_grc.py", line 231, in __init__
        self.wxgui_fftsink2_0_0.set_callback(wxgui_fftsink2_0_0_callback)
      File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/hier_block2.py", line 54, in __getattr__
        return getattr(self._hb, name)
    AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'
    i cannot find any sort of solution on the web anywhere. any sort of help will be much appreciated. thanks in advance.

    Python run time error

    yes i looked at all those threads. but i have the latest version of the program. and others that said they updated said that it was not a solution.

    I am using ubuntu 12.10 and python version 2.7.3. i run the following command in terminal:
    Code:
    matt@matt-Inspiron-1525:~$ python -m          trace --count -C . op25_grc.py
    Here is the output with an error:
