Hello
I am trying to install an OOT module into my GNURadio distribution. I
can integrate the module into GRC and use it in the flowgraph. However,
when I try to execute, I get the following Error:
Traceback (most recent call last):
File "./top_block.py", line 76, in <module>
tb = top_block()
File "./top_block.py", line 43, in __init__
self.LTE_Analysis_pbch_bch_0 = LTE_Analysis.pbch_bch(samp_rate)
AttributeError: 'module' object has no attribute 'pbch_bch'
I assume that there is some problem with the SWIG-glue between python
and my C++ code. However, several hours of googling have not brought up
any solution to this issue. As has been posted previously on this list,
this issue "has come up recently" on some installations. I have tried to
install the module and execute it on the GNURadio Live DVD that was
distributed via the mailing list yesterday - yet, the error remains.
Any help on this would be very appreciated!
I have attached some files which I think could be helpful for tracking
the error.
Best regards, Marcel
