rfnoc_image_builder cannot convert gnuradio companion files

[julixau]

Hi,

I am not sure, if this belongs here. Feel free to close this issue if this is the wrong place for it.

the rfnoc_image_builder cannot convert gnuradio-companion graphs at the moment.

rfnoc_image_builder -r example/rfnoc_radio_ddc.grc -b /usr/share/gnuradio/grc/blocks

failes with

OK, i think i have done the stupid. I now understand that there are builder blocks that need to be used here.

I will investigate further and close this issue now.
