Zend Library should have been installed automatically when you install JomSocial. However, in case of failure, you may follow these instructions to manually install Zend Library. If you did not encounter any error during installation, you do not have to go through this process.

The library need to be installed once. Subsequent upgrade of JomSocial does not require you to reinstall this library.

There are three options to install the Zend Framework.

First option: Regular Package File Installation

a. Go to Google Zend4Joomla repository and download all packs that are featured. As of July 2011, there are ten packages that need to be installed.

b. Go to Joomla Install / Uninstall, upload plg_zend_[version]_pack_1.zip. When you are done, continue pack_2, pack_3, till finish.

c. After you are done with the final pack, go to Extensions > Plugins Manager > System > Enable System - Zend Lib.

d. You may now continue with the installation of JomSocial.

Second option: Install from URL

a. Go to Google Zend4Joomla repository and click each pack to get the direct download link for the packs. As of July 2011, there are ten packages that need to be installed.

b. Go to Joomla Install / Uninstall area. Paste this link, and Install.
c. Continue with the the links for the rest of the packs.

d. After you are done with the final pack, go to Extensions > Plugins Manager > System > Enable System - Zend Lib.
e. You may now continue with the installation of JomSocial.

Third option: Install from URL

If you encounter any error during installation via the first & second method, you may want to increase your memory_limit in php.ini or follow this third option.

Installation from Directory would require you to upload the 10 plugins manually to your Joomla /tmp directory.

You could either use FTP or JoomlaXplorer (require Joomla System - Legacy plugin enabled) or eXtplorer (Native Joomla) component to be installed. You may download any of these two components here.

In this tutorial, I will be using eXtplorer component which has an easy interface similar to most FTP programs.

Part 1: Preparation

a. Go to Google Zend4Joomla repository and download all featured packs. As of July 2011, there are ten packages that need to be installed.

b. Open up eXtplorer component via Components > eXtplorer.

c. Browse to /tmp directory of your Joomla site.

d. Select Upload. Depending on your server, you could either upload all packs in one go, or to be safe, upload them one by one.

e. When you are done, you will see all packs in the /tmp directory.

f. Select pack_1 > Right Click > Extract Archive. It will create a new directory with extracted files. After extracting is complete, continue with pack_2 till finish.

Part 2: Installation

a. Go to Joomla Install / Uninstall > Install from Directory option. The system will pre-fill it with your /tmp structure. Simply append /plg_zend_1.10.6_pack_1 (refer below) and press install.

b. When you are done, continue with /plg_zend_1.10.6_pack_2 till finish. After you are done with the last pack, go to Extensions > Plugins Manager > System > Enable System - Zend Lib.
