• A computer to act as a server.
• Web server software. We reccommend Apache or lighttpd . IIS should work too
• The PHP web scripting language , version 5.2.x or later, PHP 4 should work, but we no longer support it.
• PHP-GD library.
• MySQL or PostgreSQL server. Only MYSQL 4.x and later (MySQL 3.x is not supported) and Postgresql 8.x or later are tested, older versions may or may not work, you are encouraged to report success or failures to the mailing list.
• A web browser with good support for web standards. We recommend Mozilla Firefox and Opera, but Microsoft Internet Explorer should be avoided. Internet Explorer's ability to render standard XHTML and CSS is fairly limited, and many of the w3c guidelines are implemented in quite a broken way. Please file a bug report with Microsoft to fix their browser.
• The XML extension is required for Jabber (OpenSSL recommended) and required for setup
• the “so called” “safe_mode” PHP misfeature must be disabled.
• Is highly reccommended that both magic_quotes and register_globals are set to off due to security reasons. (If you use Apache see our htaccess.dist file)
• A working SMTP server to be used as a replacement of the PHP mail() function is highly recommended but not required.

• Windows: Try XAMPP. It comes with Apache, PHP, MySQL, ADOdb… everything that you need to use Flyspray. You can also get XAMPP for GNU/Linux, Mac OS X and Solaris.
• BSD UNIX: Freshports has added a Flyspray port to their database.
