Hi at all,
I have some problem in running simulation of a block on gnuradio.
I have developed a simple block, .cc, .h, .i and .xml file attouched here.
All code is compile with success cmake/make/make install/ldconfig
but when I place the block in gnuradio, running the simulation I get
Traceback (most recent call last):
File "/home/simone/Scrivania/top_block.py", line 155, in <module>
tb = top_block()
File "/home/simone/Scrivania/top_block.py", line 106, in __init__
self.agcs_newblock_0 = agcs.newblock()
AttributeError: 'module' object has no attribute 'newblock'
Who is related this error?
Have I bad configured some file?
Thanks in advance,
Simone Ciccia#!/usr/bin/env python
