Fatal error: Call to undefined function xcache_isset()

Question

How do I install the XCache extension on Windows + WAMP + PHP 5.3 ?

I copied the extension dll in the extensions directory, and added the line in php.ini, then activated it trough the WAMP interface.

The extension appears to be active, but I still get this error :|

In order to successfully load a PHP extension, its PHP API version must match your PHP API version.

Use phpinfo to determine the exact version you have, i.e. PHP API 20090626, and download the right xdebug extension DLL, i.e. open google.com and search "xdebug dll 20090626" (without the quotes).
