[rabbitmq-discuss] compatibility with legacy code

Mon Jan 11 15:34:57 GMT 2010

Hi Alexis,

Yes :). At least managed to compile. Not tested though as yet.

This is complete set of steps that I followed ... it should (hopefully) work for anyone using RHEL 4.8

1. Downloaded rabbitmq-codegen from http://hg.rabbitmq.com/rabbitmq-codegen/archive/default.tar.gz
2. Downloaded rabbitmq-c from http://hg.rabbitmq.com/rabbitmq-c/archive/default.tar.gz
3. Copied both to /home/dinu [my home directory].
4. Download and install simplejson 2.0.5. from http://pypi.python.org/pypi/simplejson/2.0.5 .
   [The current latest version 2.0.9 is dependent on Python 2.4+ and I don't know if it will 
   work on RHEL 4.8 which comes with python 2.3+.]
5. tar -xvzf rabbitmq-c-default.tar.gz
6. tar -xvzf rabbitmq-codegen-default.tar.gz
7. mv rabbitmq-c-default rabbitmq-c
8. mv rabbitmq-codegen-default rabbitmq-codegen
9. cd rabbitmq-c
10. Edit "configure.ac" file and make the following changes 
	#sibling_codegen_dir="$ac_abs_confdir/../rabbitmq-codegen"
	sibling_codegen_dir="/home/dinu/rabbitmq-codegen"
   Note that this step was required in my environment. But that may be due 
   to something broken in the server I am using and may not be necessary for everyone.
11. autoreconf -i
12. ./configure
13. Edit librabbitmq/Makefile* (three files) and make the following modification in each
    #PYTHON=python2.5
    PYTHON=python
14. make
15. make install [I logged in as root to do the install but may not be necessary]

Lastly, for people like me, for whom the word "python" relates only to a large serpent :), 
this is how I built simplejson -

1. Download simplejson 2.0.5 source from http://pypi.python.org/pypi/simplejson/2.0.5
2. tar -xvzf simplejson-2.0.5.tar.gz
3. cd simplejson-2.0.5
4. python ez_setup.py [I am not sure if this is necessary but I did this]
5. python setup.py build
6. python setup.py install
7. I did above steps as root user.

As of now, the library seems to have built and installed correctly ... i.e. I can see

/usr/local/lib/librabbitmq.*
/usr/local/bin/amqp_* [I guess example binaries]
/usr/local/include/amqp*.h

I will test the installation and keep you posted.

Regards,
Dinabandhu
