Re: [Discuss-gnuradio] Creation of a block (PSDU 29 octets) using message passing technique

[Jose Torres Diaz]

Hi Josh, 

I've been playing around with this block and indeed it was missing in the .i file <extras_swig.i>. I included as:

%include "extras_swig.i"     //add on 21 Sept
%include "extras_blobs.i"     //add on 21 Sept <-- I added this line also

Also, I tried to change other parameters, but the problem still there. The error is:

asrp_swig.cc: In function 'PyObject* _wrap_asrp_test_temporal_sptr_detail(PyObject*, PyObject*)':
asrp_swig.cc:8800:25: error: 'class asrp_test_temporal' has no member named 'detail'
asrp_swig.cc: In function 'PyObject* _wrap_asrp_test_temporal_sptr_set_detail(PyObject*, PyObject*, PyObject*)':
asrp_swig.cc:8852:16: error: 'class asrp_test_temporal' has no member named 'set_detail'

I thought that I could remove the lines 8800 and 8852 in asrp_swig.cc for the variables that is complaining about (detail and set_detail). However, it does not compile anymore if I tried this option.

Thanks for your help, 

Regards, 

Jose.

Looks like swig is trying to understand the boost shared pointer stuff.
I usually never see this so you might be missing an include in the .i file.

Make sure you have %include<gnuradio.i> and %include<extras_swig.i>
