hi, all:
I declared a subclass of hier_block2 with two output stream ports and one input
message port in C++ , but when I connected them in a top block, the top block
can't start, it said: insufficient connected output ports (2 needed, 0
connected). But I'm sure I have connected the ports correctly. But it
will run succesfully if I do not connect the message port.
If I declare this bock in Python, the ports can be connected successfully, but there is no set_message_handler method in hier_block2 python object, so I can not process the messages.
Actually, I want to feedback something to the hier_block2.
Can anybody help me? Thanks a lot.
