Compiling the test skeleton extension

% cd /tmp/xmms
% vi config.m4

The config.m4 file

The config.m4 file adds any extension-specific configuration options. If your extension relies on external libraries and header files, you need to define those in this file and uncomment the --with-xmms section. If your extension does not rely on any external libraries, uncomment the --enable-xmms section.

Configure, build and install

% ./configure
% make
% cp modules/xmms.so /usr/local/lib/php

Testing your extension

The ext_skel script created a sample xmms.php script. A quick way to check if your extension is working is to edit this script and add dl('xmms.so') to the top. Then run it through your command-line PHP parser:

% php -q xmms.php
Congratulations! 
You have successfully modified ext/xmms/config.m4. 
Module xmms is now compiled into PHP.
