| 1 | - this program uses rabbitmq-c library (v0.3.0) |
|---|
| 2 | - https://github.com/alanxz/rabbitmq-c |
|---|
| 3 | - library installation |
|---|
| 4 | - using system package |
|---|
| 5 | - install using commands below |
|---|
| 6 | - aptitude install librabbitmq0 |
|---|
| 7 | - aptitude install librabbitmq-dev |
|---|
| 8 | - note that it is likely that system packages versions are out of date (we need v0.3.0) |
|---|
| 9 | so better use installation from source |
|---|
| 10 | - from source |
|---|
| 11 | - retrieve source |
|---|
| 12 | - wget https://github.com/alanxz/rabbitmq-c/archive/rabbitmq-c-v0.3.0.zip -O rabbitmq-c-v0.3.0.zip |
|---|
| 13 | - unzip rabbitmq-c-v0.3.0.zip |
|---|
| 14 | - cd rabbitmq-c-v0.3.0 |
|---|
| 15 | - compilation using autoconf (automake v1.9+, and libtool v2.2+) |
|---|
| 16 | - autoreconf -i |
|---|
| 17 | - if error occurs at this step, check requirement below |
|---|
| 18 | - we require autotools v2.63 or better to build. I think RHEL5 ships with v2.59 which lacks the AC_PROC_CC_C99 macro. |
|---|
| 19 | - You can do one of two things; |
|---|
| 20 | - Install a newer version of autotools |
|---|
| 21 | - Build using cmake (v2.6 or better). |
|---|
| 22 | - ./configure --enable-static |
|---|
| 23 | - make |
|---|
| 24 | - make install |
|---|
| 25 | - compilation using cmake (CMake v2.6+) |
|---|
| 26 | - mkdir build && cd build |
|---|
| 27 | - cmake -DBUILD_STATIC_LIBS=True -DBUILD_SHARED_LIBS=True .. |
|---|
| 28 | - cmake --build . |
|---|
| 29 | - make |
|---|
| 30 | - you got error AAA below, it's normal |
|---|
| 31 | make[2]: *** Pas de rÚgle pour fabriquer la cible « librabbitmq/librabbitmq.so.1.0.1 », nécessaire pour « examples/amqp_bind ». Arrêt. |
|---|
| 32 | make[1]: *** [examples/CMakeFiles/amqp_bind.dir/all] Erreur 2 |
|---|
| 33 | make: *** [all] Erreur 2 |
|---|
| 34 | - make |
|---|
| 35 | (because of the above error (AAA), you need to run make twice) |
|---|
| 36 | - make install |
|---|
| 37 | - compilation (static) |
|---|
| 38 | - gcc -static -I/usr/local/include -L/usr/local/lib -Wall -o sendAMQPMsg send_AMQP_msg.c -lrabbitmq |
|---|
| 39 | - we get warning below during compilation |
|---|
| 40 | - |
|---|
| 41 | <--- |
|---|
| 42 | /usr/local/lib/librabbitmq.a(librabbitmq_librabbitmq_la-amqp_socket.o): In function `amqp_open_socket': |
|---|
| 43 | rabbitmq-c-rabbitmq-c-v0.3.0/librabbitmq/amqp_socket.c:66: warning: Using 'getaddrinfo' in statically |
|---|
| 44 | linked applications requires at runtime the shared libraries from the glibc version used for linking |
|---|
| 45 | ---> |
|---|
| 46 | - it means that you may need to be sure all computing node have the same glibc version !!!! |
|---|
| 47 | - also means that a different binary must be use in each computing center |
|---|
| 48 | - usage |
|---|
| 49 | - to send a message in the queue, do |
|---|
| 50 | - ./sendAMQPMsg localhost 5672 test |
|---|
| 51 | - note |
|---|
| 52 | - to show how many messages are in the queue, do as root |
|---|
| 53 | - ./rabbitmqctl list_queues |
|---|
