PECL 扩展库安装

PECL 安装介绍

» PECL 是通过 » PEAR 打包系统来的 PHP 扩展库仓库，本章内容示范了怎样取得并安装 PECL 扩展。

以下指南中假定 /your/phpsrcdir/ 是 PHP 源程序的路径，extname 是 PECL 扩展库的名字。自己根据实际情况调整。此外还假定用户熟悉 » pear 命令。

要使用共享扩展库，必须经过编译，安装，然后加载。以下说明的方法提供了怎样编译和安装扩展库德各种指导，但并不会自动加载它们。可以通过将其包括在 php.ini 中用 extension PHP 指令加载，或者用 dl() 函数。

当编译 PHP 模块时，拥有各种工具（autoconf，automake，libtool 等）的已知好使的版本很重要。所需工具和所需版本的详情见» 匿名 CVS 说明。

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
