Installation of PECL extensions

Inhaltsverzeichnis

Introduction to PECL Installations

» PECL is a repository of PHP extensions that are made available to you via the » PEAR packaging system. This section of the manual is intended to demonstrate how to obtain and install PECL extensions.

These instructions assume /your/phpsrcdir/ is the path to the PHP source distribution, and that extname is the name of the PECL extension. Adjust accordingly. These instructions also assume a familiarity with the » pear command. The information in the PEAR manual for the pear command also applies to the pecl command.

To be useful, a shared extension must be built, installed, and loaded. The methods described below provide you with various instructions on how to build and install the extensions, but they do not automatically load them. Extensions can be loaded by adding an extension directive. To this php.ini file, or through the use of the dl() function.

When building PHP modules, it's important to have known-good versions of the required tools (autoconf, automake, libtool, etc.) See the » Anonymous CVS Instructions for details on the required tools, and required versions.

Tips for getting the pecl_http extension running on a Macintosh OS X 10.5.x Leopard 64-bit intel machine.



For starters, you need to follow the instructions in the subsequent pages here to install the PEAR/PECL manager because it is no longer in the standard OS X setup.



     (1) To compile the extension, you have to install the Developers XTools from your system disks because they are not installed by default. This is a simple step.



     (2) it's not made clear that you need to install an older version of pecl_http than the latest stable version (1.6.1 as of this writing) because the 1.6.1 needs PHP6. I used version 1.5.6 successfully. So, your Terminal command has to be --

sudo pecl install pecl_http-1.5.6



     (3) There is apparently a libcurl dependency in the case of pecl_http (although no dependencies are listed at the extension site), but it came with the excellent entropy.ch PHP installation I substituted for the standard PHP installation that comes with the operating system. I needed the entropy.ch version because it has the PDO_MYSQL extension and driver I need for the Zend Framework.



Note that using the entropy.ch substitute can confuse the PECL install manager (it may place the compiled extension in the wrong place for the substitute) -- it's easy enough to move (mv) it after it's successfully compiled.



     (5) Once compiled and located properly, you may need to chmod the rights for the extension. I had to to make it comparable to the others in the extensions directory -- not sure this was strictly necessary, but I thought it would help to have them similarly owned and permitted.



     (6) As is made clear elsewhere, you need to add the following to your php.ini where all other extensions to load are listed:

extension=http.so



I did not comment out the "extension_dir="./" line as some suggest, and I got no problems.



    (7) Last and perhaps most important, I had to change the underlying apache startup plist file so that it comes up in 32-bit mode --it never worked under the standard 64-bit mode. 



Here's the file to change:

/System/Library/LaunchDaemons/org.apache.httpd.plist



I've no idea if this is a so-called "bug" or just something I should have recognized on my own. Anyway, here's a link to what the substituted contents should be (found about two-thirds of the way down the page):

http://www.entropy.ch/phpbb2/viewtopic.php?p=11260#11260



Also, here's the needed substitute file contents:



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

<dict>

<key>Label</key>

<string>org.apache.httpd</string>

<key>OnDemand</key>

<false/>

<key>ProgramArguments</key>

<array>

<string>arch</string>

<string>-arch</string>

<string>i386</string>

<string>/usr/sbin/httpd</string>

<string>-D</string>

<string>FOREGROUND</string>

</array>

<key>SHAuthorizationRight</key>

<string>system.preferences</string>

</dict>

</plist>



That's it, and good luck

If it's not running for you even PEAR installed try to make an upgrade of PEAR (pear upgrade PEAR).

If you are using a Debian sarge system (currently the stable release) with php4-pear installed, you will still not have a pecl command.



The fix to this is to upgrade pear.



Unfortunately, pear upgrade PEAR will also error out stating that you need pear-1.3.3 minimum.



The fix to this is to specify the version of pear that you want to install.  In case it wasn't obvious, that means you want to

pear upgrade PEAR-1.3.3

pear upgrade-all
