Yaz Extension

Hi, I'm running PHP on an XP system (with IIS) and am having a bit of a problem with some of the extensions...the php_yaz.dll to be exact. I've set extension_dir = c:\php\extensions where all of the extensions are located. When I uncomment the extension=php_yaz.dll line, I get a warning box that pops up and states "Unknown(): Unable to load dynamic library 'c:\php\extensions\php_yaz.dll' - The specified procedure could not be found." However, the file is in fact there. I tried placing this file in the Windows and Windows\system32 folders after looking at some posts, but to no avail. I noticed that php_gd.dll worked, so I went through and tested every extension to see which ones worked to a grand total of 25 of the 46. I uninstalled and reinstalled using both the manual method and the installer, but with the same result. Does anyone have any suggestions? These were the extensions that didn't work: php_curl.dll php_domxml.dll php_flosql.dll php_gd2.dll php_gettext.dll php_iconv.dll php_ifx.dll php_iisfunc.dll php_interbase.dll php_ldap.dll php_mcrypt.dll php_mhash.dll php_msql.dll php_oli8.dll php_openssl.dll php_oracle.dll php_snmp.dll php_sybase_ct.dll php_xmlrpc.dll php_xslt.dll php_yaz.dll ************************************** Wayne Graham Systems Office Earl Gregg Swem Library College of William and Mary PO Box 8794 Williamsburg, VA 23187-8794 757.221.3112
