Hmm, that's a bit odd. I've just installed the stomp adaptor and
literally with zero config, it all just works. This is building
rabbitmq_v1_7_1 from source.

The only things I have in my plugins dir are links to
rabbitmq-erlang-client and rabbitmq-stomp.

Hmm, this is a bit odd. What we tend to recommend is that you have
everything in rabbitmq-public-umbrella, so it'd look a bit like this:

cd ~/rabbit/v1.7.1
hg clone http://hg.rabbitmq.com/rabbitmq-public-umbrella
cd rabbitmq-public-umbrella
hg clone http://hg.rabbitmq.com/rabbitmq-codegen
hg clone http://hg.rabbitmq.com/rabbitmq-server
cd rabbitmq-server
hg up -C rabbitmq_v1_7_1
make -j
cd -
hg clone http://hg.rabbitmq.com/rabbitmq-erlang-client
cd rabbitmq-erlang-client
make
cd -
hg clone http://hg.rabbitmq.com/rabbitmq-stomp
cd rabbitmq-stomp
make
cd -
cd rabbitmq-server
mkdir -p plugins
cd !!$
ln -s ../../rabbitmq-stomp
ln -s ../../rabbitmq-erlang-client
cd ..
./scripts/rabbitmq-activate-plugins
make cleandb run

Certainly, I've just run all of that lot, and it works fine for me!

"tip" is one of the daftest "features" (and there are many) of hg. You
should be at the head of default - that's certainly what I'm using.

With regards configuration, we would suggest that you use the config file
in /etc/rabbitmq/rabbitmq.config (though this can sometimes be in other
places if eg you're using macports). Having a file like:

[{rabbit_stomp, [{listeners, [{"127.0.0.1",61612}]}]}].

is by far the easiest way to configure plugins like this as it avoids
nasty escaping issues if passing by env vars.

Best wishes,

Matthew
