This is a C-language AMQP client library for use with AMQP servers speaking protocol versions 0-9-1.
Announcements regarding the library are periodically made on the RabbitMQ mailing list and on the RabbitMQ blog.
In addition to the source code for this library, you will require a
rabbitmq-codegen, which resides in the
as a git submodule. To update the submodule(s):
git clone git://github.com/alanxz/rabbitmq-c.git cd rabbitmq-c git submodule init git submodule update
You will also need a recent python with the simplejson module installed, and the GNU autotools (autoconf, automake, libtool etc.), or as an alternative CMake.
Once you have all the prerequisites, change to the
directory and run
to run the GNU autotools and generate the configure script, followed by
to build the
librabbitmq library and the example programs.
You will need CMake (v2.6 or better): http://cmake.org/
You will need a working python install (2.6+) with the json or simplejson modules installed.
You will need to do the git submodule init/update as above. Alternatively you can clone the rabbitmq-codegen repository and point cmake to it using the RABBITMQ_CODEGEN_DIR cmake variable
Create a binary directory in a sibling directory from the directory you cloned the rabbitmq-c repository
Run CMake in the binary directory
msbuild, or open it in visual studio and build from there
Things you can pass to cmake to change the build:
-DRABBITMQ_CODEGEN_DIR=/path/to/rabbitmq-codegen/checkout- if you have your codegen directory in a different place [Default is sibiling directory to source]
-DBUILD_TOOLS=OFFbuild the programs in the tools directory [Default is ON if the POPT library can be found]
Other interesting flags to pass to CMake (see cmake docs for more info)
-DCMAKE_BUILD_TYPE- specify the type of build (Debug or Release)
-DCMAKE_INSTALL_PREFIX- specify where the install target puts files
Arrange for a RabbitMQ or other AMQP server to be running on
localhost at TCP port number 5672.
In one terminal, run
./examples/amqp_listen localhost 5672 amq.direct test
In another terminal,
./examples/amqp_sendstring localhost 5672 amq.direct test "hello world"
You should see output similar to the following in the listener's terminal window:
Result 1 Frame type 1, channel 1 Method AMQP_BASIC_DELIVER_METHOD Delivery 1, exchange amq.direct routingkey test Content-type: text/plain ---- 00000000: 68 65 6C 6C 6F 20 77 6F : 72 6C 64 hello world 0000000B:

You cannot share a socket, an
amqp_connection_state_t, or a channel
between threads using
librabbitmq library is
built with event-driven, single-threaded applications in mind, and
does not yet cater to any of the requirements of
Your applications instead should open an AMQP connection (and an associated socket, of course) per thread. If your program needs to access an AMQP connection or any of its channels from more than one thread, it is entirely responsible for designing and implementing an appropriate locking scheme. It will generally be much simpler to have a connection exclusive to each thread that needs AMQP service.
