The following examples illustrate the use of SWIG with Perl.
|
|
|
|
<ul>
|
|
<li><a href="simple/index.html">simple</a>. A minimal example showing how SWIG can
|
|
be used to wrap a C function and a global variable.
|
|
<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>. This example shows how to access C global variables from Perl.
|
|
</ul>

<h2>Compilation Issues</h2>
|
|
|
|
<ul>
|
|
<li>To create a Perl extension, SWIG is run with the following options:
|
|
|
|
<blockquote>
|
|
<pre>
|
|
% swig -perl5 interface.i
|
|
</pre>
|
|
</blockquote>
|
|
|
|
<li>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 -perl5 interface.i
|
|
% gcc -fpic -c -Dbool=char -I/usr/lib/perl5/5.00503/i386-linux/CORE interface_wrap.c
|
|
% gcc -shared interface_wrap.o $(OBJS) -o interface.so
|
|
% perl
|
|
use interface;
|
|
...
|
|
</pre>
|
|
</blockquote>
|
|
|
|
<li>The politically "correct" way to compile a Perl extension module is to use MakeMaker
|
|
and related tools (especially if you are considering third-party distribution). Consult
|
|
a book such as Advanced Perl Programming for details.
|
|
|
|
</ul>
|
|
|
|
<h2>Compatibility</h2>
|
|
|
|
The examples have been extensively tested on the following platforms:
|
|
|
|
<p>
|
|
<ul>
|
|
<li>Linux
|
|
<li>Solaris
|
|
</ul>
|
|
|
|
<p>
|
|
Due to wide variations in the Perl C API and differences between versions such as the ActivePerl release for Windows,
|
|
the code generated by SWIG is extremely messy. We have made every attempt to maintain compatibility with
|
|
many Perl releases going as far back as 5.003 and as recent as 5.6. However, your mileage may vary.
|
|
