I am a beginner at Gnuradio and I am working on writing some simple
I am having a problem w. the block “Message Source”.
I got the block “Message Strobe” connected to “Message Source” (the goal
to extract the data bytes and feed them to a “Packet Encoder” block).
The graph builds OK but when run I get:
Using Volk machine: avx_64_mmx_orc
Traceback (most recent call last):
File “/home/joser/Desktop/xx/top_block.py”, line 120, in
tb = top_block()
File “/home/joser/Desktop/xx/top_block.py”, line 72, in init
NameError: global name ‘blocks_message_source_0_msgq_in’ is not defined
Any idea what the problem could be?
I checked: http://gnuradio.org/doc/doxygen/page_msg_passing.html and at
bottom is says to look at the examples in gr-blocks/examples/msg_passing
but I get missing link errors when I load these files in my setup.
My setup is gnuradio 18.104.22.168 running in Ubuntu 12.04.4 LTS.
thanks for any help,
