Subject: Re: Extending Ruby using C++ and Rice

Thanks for the suggestions.

I now have this working by doing the following:

- Removed the extern "C" as Jason suggested
- Moved my code into a dynamic library (using XCode) and included 
references to the xtoolkit library and include files.
- Ensured that the static library was being included during compilation 
in my extconf.rb then checking that it is loaded correctly:

require 'rubygems'
require 'mkmf-rice'
$LIBS << ' -lXternalDebug'
have_library("stdc++")
have_library("XternalDebug")
dir_config("xtoolkit")
dir_config("mytest")
have_library("MyTest")
have_header("MyTest.h")
create_makefile("my_test")

Added the XternalDebug to my LD_LIBRARY_PATH and my MyTest dynamic 
library to DYLD_LIBRARY_PATH

I run the extconf.rb with the following arguments:
ARCHFLAGS="-arch i386" ruby extconf.rb 
--with-mytest-include=/Users/<username>/mytest/MyTest 
--with-mytest-lib=/Users/<username>/mytest/MyTest 
--with-xtoolkit-include=/Users/<username>/xtoolkit/public/include

Kind regards,
Lea
