I’ve tried to add a new variable to an existing block,
gr-noaa/noaa_hrpt_deframer, and hoped it would show up in GRC.
I’ve modded the noaa_hrpt_deframer.cc and noaa_hrpt_deframer.h in
directory lib, noaa_hrpt_deframer.i in directory swig and added
the new variable + callback into grc/noaa_hrpt_deframer.xml
All modifications compiles.
I now uninstall and run ./bootstrap, ./configure, make and make install.
All still seems still to be OK.
When I launch GRC I can see that the modified block is missing.
It seems that also some other files must be modded?
The simple mod I made to noaa_hrpt_deframer can be viewed at
