PHLIPS - CLIPS extension for PHP

Original repository

http://phlips.sourceforge.net

Motivation

The current version of PHLIPS (0.5.1) unfortunately not compiled in new versions of PHP - releases 5.4.x, 5.5.x and 5.6.x.
I make little adjusts on source clips.c to working again.

Install

PS.: this tutorial is based on MAMP version 3.4 (acronym for Mac + Apache + MySQL + PHP), running on OS X 10.11 El Capitan.

PS.: I tested on version 5.5.3 of PHP (running on MAMP 2.2 running on OS X 10.9 Mavericks), PHP 5.5.10 (on MAMP 3.0.5 on OSX 10.10 Yosemite) and PHP 5.5.7 (on ZendServer Enterprise 6.3.0 running in Debian GNU/Linux 6.0.9 "squeeze").

1. Download

git clone https://github.com/stopassola/phlips.git
cd phlips

2. Prepare the build environment for a PHP extension

/Applications/MAMP/bin/php/php5.6.10/bin/phpize

More information in http://php.net/manual/en/install.pecl.phpize.php

This command print something like:

Configuring for:
PHP Api Version:         20121113
Zend Module Api No:      20121212
Zend Extension Api No:   220121212

---

Error: autoconf utility not available

Configuring for:
PHP Api Version:         20121113
Zend Module Api No:      20121212
Zend Extension Api No:   220121212
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.

2.1 Linux

Install the autoconf in your Linux distro:

sudo apt-get install autoconf

2.2 OS X

Open Terminal and execute the follow commands:

cd ..
curl http://ftp.gnu.org/gnu/autoconf/autoconf-latest.tar.gz > autoconf.tar.gz
tar -xzf autoconf.tar.gz
cd autoconf-x.yy
./configure --prefix=/usr/local/
make
sudo make install
export PHP_AUTOCONF=/usr/local/bin/autoconf

PS.: the autoconf-x.yy shoud be replaced by current version of autoconf. In my case: autoconf-2.69

2.3 Repeat the last command

cd ../phlips/
/Applications/MAMP/bin/php/php5.6.10/bin/phpize

If you don't enter in phplips directory (where fonts exist), the follow message appear:

Cannot find config.m4. 
Make sure that you run '/Applications/MAMP/bin/php/php5.6.10/bin/phpize' in the top level source directory of the module

2.4 Fatal error: 'php.h' file not found

If you see the follow message, it's because your PHP installation not have the source code of PHP's current release like so:

cd /Applications/MAMP/bin/php/php5.6.10/
mkdir include
cd include

Download the PHP source code from your specific instalation: http://www.php.net/releases/

cd ~/Downloads/
tar -xzf php-5.6.10.tar.gz
mv php-5.6.10 /Applications/MAMP/bin/php/php5.6.10/include/php
cd /Applications/MAMP/bin/php/php5.6.10/include/php
sudo ./configure --without-iconv

PS.: the parameter --without-iconv is important, otherwise some file is not available and errors is generated:

/Applications/MAMP/bin/php/php5.6.10/include/php/Zend/zend.h:51:11: fatal error:
      'zend_config.h' file not found
\# include <zend_config.h>
          ^
1 error generated.

and

/Applications/MAMP/bin/php/php5.6.10/include/php/Zend/../TSRM/TSRM.h:20:11: fatal error: 'tsrm_config.h' file not found
\# include <tsrm_config.h>
          ^
1 error generated.

2.5 PHP environment is ready!

3. Specify the installation of PHP

If you have multiple PHP versions installed, you may be able to specify for which installation you'd like to build by using the --with-php-config option during configuration:

cd phlips_source_directory
./configure --with-php-config=/Applications/MAMP/bin/php/php5.6.10/bin/php-config`

---

Error: C compiler is not available

checking for gcc... no
configure: error: in `/home/zend/phlips':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.

Install compiler utilities on your Linux distro and repeat the last command:

sudo apt-get install build-essential

In OSX make sure to install the Xcode with command line: xcode-select --install

4. Build module clips.so from source code

sudo make

5. Copy the clips.so module to MAMP repository:

cp modules/clips.so /Applications/MAMP/bin/php/php5.6.10/lib/php/extensions/no-debug-non-zts-20131226/

6. Load the CLIPS extension (clips.so) in php.ini (configuration file of PHP)

extension=clips.so

7. Restart the webserver

sudo /usr/local/zend/bin/apachectl restart

(command above tested in ZendServer Enterprise 6.3.0 running in Debian GNU/Linux 6.0.9 "squeeze")

8. Check if extension was install

<?php
phpinfo();
?>

You should view the clips extension:

9. Test some expert system code:

<?php
clips_clear();
clips_set_strategy(LEX_STRATEGY);
clips_assert("(quesito 2)");
clips_run();
$facts = clips_get_fact_list();
print_r($facts);
?>
