xml-rpc is no longer bundled with the PHP source code as of PHP 8.0.
You'll need to get it from PECL. Many distro and third party repos may still ship it (tho the package name may have changed to reflect the move to PECL)
Le support de XML-RPC n'est pas activé par défaut en PHP. Vous devez l'activer avec l'option de compilation --with-xmlrpc[=DIR].
