<h2 class="title">Building PHP for extension development</h2>
<p class="para">
In a typical PHP installation, the need for high performance almost always
results in optimization at the cost of debugging facilities. This is a
reasonable tradeoff for production use, but when developing an extension it
falls short. What we need is a build of PHP which will give us some hints
what has gone wrong when something does.
</p>
<p class="para">
The Zend Engine provides a memory manager which is capable of tracking
memory leaks in extensions and providing detailed debugging information.
This tracking is disabled by default, as is thread-safety. To turn them
on, pass the <span class="option">--enable-debug</span> and
<i>--enable-maintainer-zts</i> options to
<var class="filename">configure</var>, along with whatever options you typically
use. For instructions on building PHP from source, see the instructions at
<a href="install.general.php" class="xref">General Installation Considerations</a>. A typical <var class="filename">configure</var>
line might look like this:
</p><div class="example-contents programlisting">
<div class="shellcode"><pre class="shellcode">$ ./configure --prefix=/where/to/install/php --enable-debug --enable-maintainer-zts --enable-cgi --enable-cli --with-mysql=/path/to/mysql</pre>
</div>
