Re: [Discuss-gnuradio] Help needed with message ports

[Michael Dickens]

Hi Volker - OK thanks for the update. After rechecking my OOT example, I agree 
that this issue requires inheritance from a hier2_block class. Maybe that will 
help track down the issue... ? I know that the code for doing connections is 
pretty gnarly, so who knows? Anyway, worth poking at ... and please do let 
me/the list know of progress. I'll do the same if/when I get a chance to look 
at this issue. - MLD
