Hi all, I'm working on a system with trellis coding and I met a problem with the python callback function generated by grc . Because there are several parameters used in the blocks needs to be updated. I added callback functions for those parameters in those c++ files. For example, to add callback function for the FSM parameter in the viterbi_combined block, I declared set_FSM function in viterbi_combined.h , defined the function in viterbi_combined_impl.h, and added <callback> set_FSM($FSM) </callback> in the viterbi_combined.xml file. After that, I reinstalled the gnuradio and checked the trellis_swig.py and confirmed that python has linked these callback functions in the viterbi_combined class. But when I execute the grc application, this callback function wasn't automatically generated in the resulting python file. After I added this set_FSM function by myself, the flow graph worked as what I expected. I've added callback functions for other blocks like repack_bits of gr-block module. After I've done exactly the same thing, the callback function I added was correctly generated in python file after I executed in grc. So my question is: why these callback functions I added in gr-trellis weren't automatically generated in python file after execution in grc like the other callbacks in gr-blocks? Did I do anything wrong? I attached my modification on gnuradio in the patch file for your reference. Thanks!
