All add-ons
Ruby extension: This is a simple C extension to Ruby that wraps WireAPI.
Win32 builds with DLLs: This package provides Win32 builds of the OpenAMQ software including DLLs.
Hi,
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,
Carl
1.) Install ruby-full in your machine.
I would suggest to use something like "sudo apt-get install ruby-full "
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 use ruby with OpenAMQ-1.3c5.tar.gz and like to share a few small improvements for the tips above.
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.
If you try to build the ruby extension with OpenAMQ-1.2d1 in Intel 64 bit system you will probably end up with a following error.
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.

Eranga
