Re: [Discuss-gnuradio] Error using block UHD AMsg Source

[Jose Torres Diaz]

Hi Josh, 

I've changed the .xml file. Also, I've checked the new top_block.py file and it is generated as follows:

self.extras_uhd_amsg_source_0 = gr_extras.uhd_amsg_source(uhd.device_addr="172.17.3.140"

However, it is still complaining when I run the flow graph:

  File "/home/asrpuser/Desktop/Jose Torres Material /top_block.py", line 33
    self.extras_uhd_amsg_source_0 = gr_extras.uhd_amsg_source(uhd.device_addr="add=172.17.3.140")
SyntaxError: keyword can't be an _expression_

Thanks, 

Jose.

I see. Its the xml definition. Too bad python/swig does get the
constructor overloads that c++ sees.

I pushed this change to the repo:
