Route planner doesn't show any results

[pietercolpaert]

I've built the master branch of this repo (5th of April 2014)

I've used the gtfs tec available from the openov website and built it according to the readme (successfully as far as I can see)

I've had to change some code in client.c in order for the code itself to compile:

# Takes only 3 arguments said the error
-       zmq_send(sock, &req, sizeof(req), 0);
+        zmq_send(sock, &req, sizeof(req));

I've compiled it successfully but when I now try to calculate a route, nothing is returned.

Is this due to me changing the zmq line or to something else?

Could you try to run cliënt in gdb? On 6 Mar 2015 11:07, "Pieter Colpaert" notifications@github.com wrote:

Mmh that does imply something wrong with zmq. What ZMQ version are you using?

[pietercolpaert]

Latest master of https://github.com/zeromq/czmq

[pietercolpaert]

And same thing happens with 3.0.0

We always hated the czmq thing for this kind of FUBAR. What are you trying to do btw? If you are trying to webserver, we dogfood https://github.com/bliksemlabs/webserver/tree/handler_rrrr_realtime_expanded2 ourselves. The current dev work is really focussed on the ansi branch, which is rewrite of master in ANSI C currently only lacking the client/worker construction and embedded webserver. The master branch is now kind of in purgatory.
