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

[Jose Torres Diaz]

Hi Josh, 

Now it is running. Also, I add some lines into the uhd_amsg_source.cc file for debugging purposes:

Just ordinary prints to see when the message is post and what kind of message:
 std::cout << std::endl << "interruption"<<std::endl;

When I run the flow graph shows:

Executing: "/home/Desktop/Jose Torres Material /top_block.py"

linux; GNU C++ version 4.6.1; Boost_104601; UHD_003.004.003-221-g9d6f9492

-- Opening a USRP2/N-Series device...
-- Current recv frame size: 1472 bytes
-- Current send frame size: 1472 bytes


And stays there (it does not show my debugging lines). Do you see the same lines than me above, or stops at some point?.

Thanks for your help, 

Regards, 

Jose.

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:
