Cannot load the mysql library

Hello people! I’m using PHP 5.0.2, IIS 5.1 running on WinXP Pro. But the installer for IIS don’t install the MySQL functions library and, after installing the MYSQLX.exe (http://dev.mysql.com/get/Downloads/Contrib/MYSQLX.EXE/from/pick), I copied the php_mysql.dll from the PHP 5.0.2 ZIP file to the extensions directory (php/ext/) and uncommented the line “extension=php_mysql.dll” in php.ini. When I open the page, I receive the message: “PHP Startup: Unable to load dynamic library ‘./ext/php/_mysql.dll’ – Can’t find the specified module”. I don’t know if this is the exact message, because the original is in Portuguese: “(…) – Não foi possível encontrar o módulo especificado”. Note: I have the php_gd2.ddl library installed in the same place and it’s working well, so the path is correct. I’ve exhausted my possibilities and can’t wonder what is wrong… Please somebody help me! Tks Rafael | AgênciaM Fone: +55 |11| 4616-1394
