[07:44] guido_g just compild 0mq, tried epgm, doesn't work *grml*
[07:55] guido_g guido@nathan:~/prog/apps/zmq-trunk/perf$ ./local_thr epgm://eth0\;239.1.1.1:5000 800 1000000
[07:55] guido_g Assertion failed: false (pgm_socket.cpp:130)
[07:55] guido_g Aborted
[07:55] guido_g should work, shouldn't it?
[08:02] guido_g forgot to set ZMQ_RATE
[08:50] sustrik guido_g: still, it shouldn't assert
[08:51] sustrik can you possibly find out what error did OpenPGM returned that caused the assert?
[08:52] guido_g omg, multicast kills the wifi router :(
[08:52] sustrik yes, it does :)
[08:53] sustrik set the rate to very low to keep it alive
[08:53] guido_g i turned wifi of, now it works
[08:54] guido_g *sigh*
[08:54] guido_g the world is not ready for multicast
[08:56] guido_g guido@nathan:~/prog/apps/zmq-trunk/perf$ ./local_thr epgm://192.168.1.5\;239.1.1.1:5000 500 100000

[08:56] guido_g nice one
[08:58] sustrik looks like OpenPGM bug, 0MQ itself doesn't use glib
[08:59] guido_g ah thx
[09:04] guido_g ok, and now for the python bindings...
[09:19] guido_g yes! success! :)
