[rabbitmq-discuss] Rabbit Erlang Client on Windows

[Matthew Sackman]

Hi Colin,

Sorry for the delayed response, we've been somewhat snowed under here.
Or more accurately, meteorologically, drowned.

Right, that's your problem. The Erlang client shares code with the
server. Now in the past we did have a big push to make sure you could
compile the client without needing the source of the server, and it did
work correctly like that for a while. I have a horrible feeling though
that this is broken, maybe this happened when plugins came in. There is
no fundmental reason, as far as I know, why the client requires the
server sources.

Yup indeed.

Hmm. I'm not a python expert so I don't know. I'm using Python 2.5 here
and that works fine. I wonder whether this is python 3000 issue.

I'm afraid, I'd suggest trying a python before 3000. If that does work
for you then please let us know. I guess we're going to have to rewrite
all our python scripts for python 3000. Joy.
