I am using using ubuntu 12.10 i am trying to run a python block, namely OP25,
in GNU Radio Companion v3.6.3-35-g4435082f, which uses python version 2.7.3 for
some reason although python3.2 is in the lib folder. I run the following trace
command in terminal:
~$ python -m trace --count -C . op25_grc.py
Here is the output with an error:

My goal is to fix the error: AttributeError: "'gr_hier_block2_sptr' object has no attribute
'set_callback'" so that the block "op25_grc.py" will run in GNU radio companion.
i have been unable to find any sort of solution to this problem anywhere. some
have said its a version problem with GNUradio but as i posted above i have the
latest version.
Any help will be greatly appreciated. Thank you very much!
I'm rather surprised somebody hasn't jumped in by now. I thought your
reworded query was quite well done. One of the source files is pretty
large, but it's not your code, so that perhaps cannot be helped. I'm
not sure why you included the code from hier_block2_.py, as I cannot see
any reference to it.
I'm surprised at the comment in the first file that said the code was
generated. if it was generated by your efforts, perhaps there was
something wrong with that.
I know nothing about this gnuradio thingie, and you didn't supply a
website url. I was wondering if the module is even intended to be run
standalone, but I suppose the if __name__ == "__main__" thing is a clue
that it's supposed to.
I found the mixture of trace lines to confuse the stack trace immensely,
since the exception doesn't occur in the last source line quoted.
Somebody better than I had best jump in and help.
The error message referenced class gr_hier_block2_sptr, but I don't see
where this is defined. So I'm not sure how to tell whether it does or
should have a set_callback method.
If nobody else jumps in, I'd suggest finding a forum that supports
gnuradio, and ask there.
