I am trying to write a C++ block that uses the GRExtras block
interface, but am having some difficulty figuring out how to include
the proper headers in my swig.i file. If I use GR_SWIG_BLOCK_MAGIC2
along with my block name, I get the following error when building
swig:
error: ‘InputItems’ was no
Adding those includes to my .i file fixed it. Thanks!

Well, I guess it fixed the compilation problem, but now I am having a
problem when I try to import the swig module in Python:
Traceback (most recent call last):
File "/root/mockup_test.py", line 15, in
import argon
File "/usr/lib64/python2.6/site-packages/argon/__init__.py", line
45, in
Is it possible to use a vector input or output with a block that uses
the GRExtras interface? All of the examples for specifying the I/O
signature for a Python block only show using a numpy type to specify
the data width.
I also tried creating a C++ block and setting the sizeof_stream_item
parame
Is it possible to create hierarchical blocks that have GrExtras
messages as the inputs or outputs? The standard pad source and sink
blocks don't appear to provide a way to do this.
Thanks,
Roy

That seems to work, I didn't realize that grc would allow connecting a
message port to a byte port.
Thanks for your help.

I am starting to play around with 3.6.3rc0 a little bit. I'm excited
about the new message passing infrastructure and the Python-based
signal processing blocks. In fact, I would really like to be able to
create Python-based blocks that use the new message infrastructure.
However, as best I can te
so it is useful that they can communicate with
the rest of the blocks via the messaging infrastructure.
Thanks,

What version of GNU Radio are you using? Message ports with Python blocks
are supported as of 3.6.4:
class message_consumer(gr.sync_block):
def __init__(self):
gr.sync_block.__init__(
self,
name = "message consumer",
in_sig = None,
out_s
I was able to get this working by simply catching an exception when
attempting to import Colors. This seems to be the source of the problem
and you don't really need that module when running grcc. See attached
patch.
