Hi,
I have debugged a bit on this. There's a lot of code, and I don't have
the total overview at the moment but what I have found is:
- I start pathopub tcp://127.0.0.1:5557
I then debug lvcache and it seems there is a problem with the
subscriptions. When lvcache attemps to add subscription it seems to end
up here:
void zmq::dist_t::distribute (msg_t *msg_)
{
// If there are no matching pipes available, simply drop the message.
if (matching == 0) {
and matching is 0, so the message is dropped.
I haven't understood the pipes yet, but it seems there is a problem when
establishing the pipes, which causes matching to remain at 0...
Any ideas?
Thanks,
Ingar

e checked
the setup, and I'm using tcp://127.0.0.1:5557 for the publisher and
tcp://127.0.0.1:5558 for the subscriber... Thanks! best regards Ingar F
