Writing C Modules with Inline::C

Modifying Makefile.PL

However, before I can get started, the generated Makefile.PL requires some modi 

fication to build an Inline::C module (see Listing 10 1).

Listing 10 1. Makefile.PL for Inline::C Version of Gnome::MIME

use Inline::MakeMaker;

WriteInlineMakefile(

                     NAME          => "Gnome::MIME",

                     VERSION_FROM  => "MIME.pm",

                     PREREQ_PM     => { Inline::C => 0.43 },

                      AUTHOR        =>  Sam Tregar  ,

                    );

This file is considerably different from the version created for XS. First, it starts 

by using a different MakeMaker module:

use Inline::MakeMaker;

Also, it calls WriteInlineMakefile() rather than WriteMakefile(). Inline::C 

modules use a different MakeMaker to allow them to be compiled and installed 

just like XS modules rather than being compiled the first time they're used. Also, 

notice that Inline::C is listed as a requirement in PREREQ_PM:

PREREQ_PM     => { Inline::C => 0.43 },

A future version of Inline::C will make it possible to build modules that do not 

depend on Inline::C, but at least for version 0.43 users of Inline::C based modules 

must also install Inline::C.

What's new isn't as notable as what's missing the calls to gnome config to set 

up LIBS and INC. This logic will still be needed by the module, but it will go in the 

module itself rather than living in the Makefile.PL.

Modifying MIME.pm

The configuration that was part of Makefile.PL in the XS version is now part of 

MIME.pm (Listing 10 2).
