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 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.
