Before you start installation make sure that <em class="emphasis">libfann</em> is installed
on your system. It's part of the main repository in the most Linux distributions
(search for `fann`). You need a development version.
</p>
<p class="para">
If it is not installed, you need to install it first. Either download it from the
<a href="http://leenissen.dk/fann/wp/" class="link external">» official site</a> or get it from your distro
repository. For example on Fedora:
<div class="example-contents">
<div class="cdata"><pre>
$ sudo yum install fann-devel
</pre></div>
</div>
or Ubuntu:
<div class="example-contents">
<div class="cdata"><pre>
$ sudo apt-get install libfann-dev
</pre></div>
</div>
</p>
</div>
<div class="section" id="fann.installation.pecl">
<h2 class="title">PECL Installation</h2>
<p class="para">
This extension is available on PECL. The installation is very simple. Just run:
<div class="example-contents">
<div class="cdata"><pre>
$ sudo pecl install fann
</pre></div>
</div>
</p>

For developers and people interested in the latest changes, you
can compile the driver from the latest source code on
<a href="https://github.com/bukka/php-fann" class="link external">» Github</a>.
Go to Github and click the "Download ZIP" button. Then run:
<div class="example-contents">
<div class="cdata"><pre>
$ unzip php-fann-master.zip
$ cd php-fann-master
$ phpize
$ ./configure
$ make all
$ sudo make install
</pre></div>
</div>
</p>
<p class="para">
Make the following changes to php.ini:
</p>
<ul class="itemizedlist">
<li class="listitem">
<p class="para">
Make sure the <em class="emphasis">extension_dir</em> variable is pointing to
the directory containing <em class="emphasis">fann.so</em>. The build will display where
it is installing the PHP driver with output that looks something like:
<div class="example-contents">
<div class="cdata"><pre>
Installing '/usr/lib/php/extensions/no-debug-non-zts-20060613/fann.so'
</pre></div>
</div>
Make sure that it is the same as the PHP extension directory by runnning:
<div class="example-contents">
<div class="cdata"><pre>
$ php -i | grep extension_dir
extension_dir => /usr/lib/php/extensions/no-debug-non-zts-20060613 =>
/usr/lib/php/extensions/no-debug-non-zts-20060613
</pre></div>
</div>
If it's not, change the <em class="emphasis">extension_dir</em> in php.ini or
move <em class="emphasis">fann.so</em>.
</p>
</li>
<li class="listitem">
<p class="para">
To load the extension on PHP startup, add a line:
<div class="example-contents">
<div class="cdata"><pre>
extension=fann.so
</pre></div>
</div>
