I've stepped up to GR 3.7.0, re-used gr_modtool to freshly re-create my OOT
module, everything builds, tests, installs OK. GRC has my OOT blocks listed and
I can put them on my flowgraph.
One of my OOT blocks is a function that takes in shorts and outputs shorts (a
1-to-2 interpolator).
I have a simple flowgraph created in GRC: File Source -> My block -> File
sync .
GRC is happy until I run the flowgraph, and I get this:
Executing: "<....> /top_block.py"
Traceback (most recent call last):
File "<....> /top_block.py", line 54, in <module>
tb = top_block()
File "<....> /top_block.py", line 39, in __init__
self.connect((self.my_block_s_to_s_0, 0), (self.blocks_file_sink_0, 0))
File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/top_block.py", line
130, in connect
self._connect(points[i-1], points[i])
File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/top_block.py", line
141, in _connect
self._tb.primitive_connect(src_block.to_basic_block(), src_port,
AttributeError: 'function' object has no attribute 'to_basic_block'
Platform: Ubuntu 12.04 on VMware x86
The File Source and Sink blocks came from the "File Operators" collection in
GRC.
If I delete my block from the middle, leaving File Source -> File Sink, it runs
OK.
Any ideas? This worked fine when the system was GR 3.6.4.2 based.
Thanks,
Tim
