problem using make to compile the rabbitmq_erlang_client

[rahulsaxena306]

Trying to follow these instructions to build erlang AMQP client: https://www.rabbitmq.com/build-erlang-client.html

When I type-in make, I see that some of the compilation is failing, giving issues in erlang.mk, I think because of this partial compilation, when I do applications: ensure_started(amqp_client) - it doesn't work. -thus I am not able to get the client up and running to connect to RabbitMQ server: Pasting the error below on typing in make command.

Do you have the public_key application in your Erlang installation? Some distributions split up Erlang into multiple packages and this causes this kind of issues.

[rahulsaxena306]

The build instructions for the client mentions that as soon as you type make, it'll take care of dependencies and hence, installation of Erlang as well. I installed erlang separately using apt-get as well, just in case. As for your question, I don't really know how to check that if I have used apt-get to install erlang.

[essen]

Perhaps the build instructions are confusing, what they mean is that RabbitMQ and 3rd party dependencies are fetched automatically, but you still need Erlang installed properly. Because public_key is part of Erlang it can't be fetched like other libraries.

If you are on a Debian-based system then you need
the `erlang-nox`, `erlang-dev` and `erlang-src`
packages installed. If you are building and installing
Erlang from source then you must ensure that
`openssl` is installed on your system.

I'm not sure if the instructions are enough or if packages have changed since.

[rahulsaxena306]

I tried reinstalling erlang , and running make command again. No red markers or errors this time, which is very confusing.

Since, it seemingly didn't give me any errors, I went ahead to /ebin directory inside the client folder.( It contains amqp_client.app file). According to instructions: https://www.rabbitmq.com/erlang-client-user-guide.html#example , I opened an erlang shell in that directory and typed 'application:ensure_started(amqp_client). It showed error there, something along the line of "not started, xmerl". Xmerl is installed though.

Probably because you want application:ensure_all_started(amqp_client).

Anyway since there doesn't seem to be an issue, if you need RabbitMQ support please use their mailing lists, or the Erlang mailing lists or channels for Erlang questions.
