What does your message_port_register_in call look like?
Or is it a message_port_register_hier_in call? (should it be?)
Cheers,
Marcus

NemanjaCould it be that problem is something with strings (I am not sure is null character is passed, no idea)?So, later on, at the end of hier block I call:body of constructor:out_port is passed to constructors of all transmitting blocks. They are passed as type const char*. Blocks have member d_msg_out_port defined as string. So something like this:in_port is receiving port of a block that receives messages from blocks which have registered out_block as their transmitting port.These arguments are passed in the following way:out_port='out_port'in_port = 'in_port'So i have hier block written in python where i defineHi,ok thanks. Does it matter how I everything is declared, but it is clear that something changed since 3.6.5.1.
d_msg_out_port(msg_out_port)
...
message_port_register_out(pmt::mp(d_msg_out_port));
self.msg_connect(self.SFL_90518279_pkt_def, out_port, self.db_logger, in_port)

Hi,
not really, what it says is really "I can't find <element> in <list of elements>", with that list being the names of the registered ports.
So, the interesting thing is that seemingly,comparin pmt::symbol("in_port") with pmt::symbol("in_port") doesn't quite work well.
I'd have to look into what pmt::comparator looks like; it's my first suspect for why that might fail.

NemanjaHi,hm, could just tell me if I am thinking wrong, but this looks like some of my blocks is also called in_port?

Hi Nemanja,
a blind suspicion: as "system" is a port that should be registered by the runtime for each block, there might be some confusion happening.
Does it work better when you rename your block to something else?
Best regards,
Marcus

Thanx,I see that there is a function for checking whether the ports are valid, but don't get what's wrong with my ports. Namely, I have hier block and a few blocks are sending messages to a single blocks where the messages are decoded and written to darabase. I tried to hardcode names of the blocks and that also didn't help.I was using message passing in some of my blocks, but now I get error which is following:Hi all guys,I recently installed 3.7.8, and before that I had 3.6.5.1.
