This is a frequent issue dealing with Python but how do we want to deal with strings? Python strings are a bit cumbersome when dealing with C. For example to use the Zyre bindings in python one needs to do one of the following: > from zyre import Zyre > zn = Zyre(b'MyZyreNode') or > zn =

Re: [zeromq-dev] Cinder-ZeroMQ block

I'm not sure how Cinder works internally but I guess it is similar to OpenFrameworks. It then probably will be typical 'game loop' based. So running anything blocking kills the framerate. You can do a poll with 0 timeout but better would be to replace the sleeping of the loop with polling.

This is an assertion error and then an error in the destructor. I need to look into that. What if you just add a single socket? Rg, Arnaud On November 3, 2015 10:55:57 PM GMT+01:00, Johan Philips <johan.phil...@kuleuven.be> wrote: > > >On 2015-11-03 19:31, Arnaud Loonstra wr

[zeromq-dev] Question about python binding generator

Hi all, I'm a bit puzzled. For example if I use czmq's zsock in Python I can retrieve the underlying socket using the resolve method. This method is defined as a static method in Python: https://github.com/zeromq/czmq/blob/master/bindings/python/czmq.py#L2233 The way it is defined I need to

Ok, I played with android studio a bit. Djeez, these dependencies fill my harddrive faster than I can empty. :S Anyway, just build a simple app and ran it on a emulator: Unfortunately, ZyreTest has stopped It seems it can't find the czmq libs? 01-06 15:15:20.295 1257-1257/org.z25.zyretest

I have hardly any experience either but I asked a colleague. We just created a simple app with zyre = new Zyre("android_test"); zyre.start(); in the constructor and zyre.stop() in the destructor. 01-05 13:45:05.769 8364-8364/org.z25.zyretest I/art: Late-enabling -Xcheck:jni
