step 2 above modifies the ruby API but since this is a method of connection the modification can be better:
amq_connection.h:126 remove second parameter from this function
amq_connection.h:132 change the first parameter to self

the connection object is already known so the change above could allow something inconsistent where the object and the argument are different.

in step 8 the change in line 20 will be no longer needed

to make the binding compile I needed to change $AMQ_HOME/include/apr.h:270 in such way that __off64_t is used instead of off64_t. This must be the same after including 'sys/types.h' but for some reason it doesn't work always.

Line 16 of test.rb call connection.error_text but this leads to a segfault, after removing this line it worked, until I find a better way to fix this problem.

relocation R_X86_64_32 against ‘a local symbol’ can not be used when making a shared object; recompile with -fPIC
/opt/ibaseold//lib/libamq_wireapi.a: could not read symbols: Bad value

You can an idea about this error from the following link.
http://www.gentoo.org/proj/en/base/amd64/howtos/index.xml?part=1&chap=3#doc_chap7

How could you overcome this issue?
Rebuild the OpenAMQ-1.2d1 with following additional options.

export CCDEFINES="-fPIC"
export CFLAGS="-fPIC"
export BASE_THREADSAFE="-DBASE_THREADSAFE"

Then follow the regular build steps.

Then you need to follow the instruction I was given in my previous post.

2.)Open the "amq_client.c" file.
Change the line 197 as follows

old -> rb_define_method(amqp_connection,"client_session_new", con_client_session_new,0);
new-> rb_define_method(amqp_connection,"client_session_new", con_client_session_new,1);

2.)Remove the Makefile in the distribution.

3.)Open extconf.rb in a text editor.
Chnage it to

require 'mkmf'
$INCFLAGS += ' -I${AMQ_HOME}/include'
$LIBS += ' -L${AMQ_HOME}/lib -Wl,-rpath=${AMQ_HOME}/lib -lamq_wireapi -lamq_common -lsmt -licl -lipr -lasl -lapr -laprutil -lpcre'
create_makefile("open_amqp")

4.)Set OpenAMQ home
export AMQ_HOME=/opt/amq

5.)Generate make file using command
ruby extconf.rb

6.)Build ruby library using command
make all

7.)Start your OpenAMQ server
cd ${AMQ_HOME}/bin/
./amq_server

8.)Open the test.rb file
Change the line 14 as follows

old -> auth_data = foo.client_connection_auth_plain("guest","foobar")
new -> auth_data = foo.client_connection_auth_plain("guest","guest")

Comment the line 17

Change the line 20 as follows

old -> session = connection.client_session_new
new -> session = connection.client_session_new(connection)

Save your changes.

9.) Run sample program
ruby test.rb

10.) Enjoy ! :)

I'm trying to compile this wrapper on Ubuntu and it keeps failing. Are there any specific build instructions?

I have ruby and ruby-dev installed.

Best Regards,
