[erlang-questions] Use Erlang AMQP client library

Wed Dec 16 18:36:01 CET 2015

Hi,

The better place to ask this sort of questions is at rabbitmq-users mailing
list.

But to summarize:
- Failure with rebar is an expected outcome, it's not the right build tool
- Failure with source tarball and `make` is an error - I've filed an issue
at https://github.com/rabbitmq/rabbitmq-erlang-client/issues/29
- Failure to build from github checkout with `make` - couldn't reproduce
it. Probably it's some problem with your build environment, but more
details are needed if you want help from somebody )

Best,
Alexey
