php-xmlrpc-all-dev 3:1.0.0~rc3-6ubuntu2 (riscv64 binary) in ubuntu noble

 These functions can be used to write XML-RPC servers and clients. You can find
 more information about XML-RPC at http://www.xmlrpc.com/, and more
 documentation on this extension and its functions at
 http://xmlrpc-epi.sourceforge.net/.
 .
 The extension is unbundled from php-src as of PHP 8.0.0, because the underlying
 libxmlrpc has obviously been abandoned. It is recommended to reevaluate using
 this extension.
 .
 This is empty package that depends on all PHP versions.
