- <p>
- The following examples illustrate the use of SWIG with Ruby.
- <ul>
- <li><a href="simple/index.html">simple</a>. A minimal example showing how SWIG can
- be used to wrap a C function, a global variable, and a constant.
- <li><a href="constants/index.html">constants</a>. This shows how preprocessor macros and
- certain C declarations are turned into constants.
- <li><a href="variables/index.html">variables</a>. An example showing how to access C global variables from Ruby.
- <li><a href="value/index.html">value</a>. How to pass and return structures by value.
- <li><a href="class/index.html">class</a>. Wrapping a simple C++ class.
- <li><a href="reference/index.html">reference</a>. C++ references.
- <li><a href="pointer/index.html">pointer</a>. Simple pointer handling.
- <li><a href="funcptr/index.html">funcptr</a>. Pointers to functions.
- <li><a href="enum/index.html">enum</a>. Enumeration.
- </ul>
- <h2>Compilation Issues</h2>
- <ul>
- <li>To create a Ruby extension, SWIG is run with the following options:
- <blockquote>
- <pre>
- % swig -ruby interface.i
- </pre>
- </blockquote>
- <li>
- Please see the <a href="../../Doc/Manual/Windows.html">Windows</a> page in the main manual for information on using the examples on Windows. <p>
- </li>
- <li>On Unix the compilation of examples is done using the file <tt>Example/Makefile</tt>. This
- makefile performs a manual module compilation which is platform specific. Typically,
- the steps look like this (Linux):
- <blockquote>
- <pre>
- % swig -ruby interface.i
- % gcc -fpic -c interface_wrap.c -I/usr/local/lib/ruby/1.4/i686-linux
- % gcc -shared interface_wrap.o $(OBJS) -o interface.so
- % ruby
- require 'interface'
- Interface.blah(...)
- ...
- </pre>
- </blockquote>
- <li>The politically "correct" way to compile a Ruby extension is to follow the steps
- described <tt>README.EXT</tt> in Ruby distribution:
- <p>
- <ol>
- <li>Create a file called <tt>extconf.rb</tt> that looks like the following:
- <blockquote>
- <pre>
- require 'mkmf'
- create_makefile('interface')
- </pre>
- </blockquote>
- <li>Type the following to build the extension:
- <blockquote>
- <pre>
- % ruby extconf.rb
- % make
- </pre>
- </blockquote>
- </ol>
- </ul>
- <h2>Compatibility</h2>
- The examples have been extensively tested on the following platforms:
- <ul>
- <li>Linux
- </ul>
