## Installation

Obtain YAZ (ANSI/NISO Z39.50 support) and install it. YAZ can be fetched in source or in various prebuilt packages from the » YAZ archive. Systems such as Debian GNU/Linux, Suse Linux, FreeBSD also has YAZ as part of their distribution.

For the PHP 4 series, the YAZ extension is bundled (but not YAZ itself) Build PHP with your favorite modules and add option --with-yaz[=DIR].

Example #1 YAZ compilation for PHP 4 on Unix

    gunzip -c php-4.4.X.tar.gz|tar xf -
    gunzip -c yaz-2.1.8.tar.gz|tar xf -
    cd yaz-2.1.8
    ./configure --prefix=/usr
    make
    sudo make install
    cd ../php-4.4.X.
    ./configure --with-yaz=/usr/bin
    make
    sudo make install

For PHP 5, the YAZ extension is in » PECL and is installed as a shared object/dll. If you have pear installed the easiest way to download, configure and install the YAZ extension is by using the pecl command.

Installation of YAZ on Linux

Information for installing this PECL extension may be found in the manual chapter titled Installation of PECL extensions. Additional information such as new releases, downloads, source files, maintainer information, and a CHANGELOG, can be located here: » http://pecl.php.net/package/yaz

Installation on Windows systems

A DLL for this PECL extension is currently unavailable. See also the building on Windows section. php_yaz.dll depends on yaz.dll. The yaz.dll is part of the Win32 ZIP from the PHP site. It is also part of the Windows YAZ install available from the » YAZ WIN32 area.

Warning

The PHP 5.0.5 Win32 zip includes a too old version of yaz.dll (version 1.9.1 < required version 2.0.13). If that's the case use the yaz.dll from a newer » YAZ WIN32 install.

On windows, don't forget to add the PHP directory to the PATH, so that the yaz.dll file can be found by the system.

If you are using YAZ as a shared extension, add (or uncomment) the following line in php.ini on Unix:

extension=yaz.so
And for Windows:
extension=php_yaz.dll
Warning

The IMAP, recode, YAZ and Cyrus extensions cannot be used in conjuction, because they share the same internal symbols.

> Note: The above problem is solved in version 2.0 of YAZ.
