LIXA wrapper might be dynamically generated using SWIG: you should install SWIG on your system in advance if you desired to build the wrapper from scratch. Most times, the LIXA distributed wrapper works fine and you don't have to generate a fresh one.

PHP needs some specific versions of autoconf as explained in Talking to the UNIX build system: config.m4; you must install the right version of autoconf before going on. Without a valid version of autoconf you will not be able to build a Zend PHP engine.

For the sake of easiness, this manual shows how to build a fresh PHP Zend environment patched with the LIXA provided extension. You could patch your own previously downloaded PHP environment, but this manual tries to keep it simple and uses a freshly downloaded tarball.
