How to enable SimpleXML extension in PHP (Gentoo OS)

Question

I am working on a gentoo server. Currently in PHP, the SimpleXML extension is not enabled. How do I enable this extension ?

The PHP version is 5.2

The configure command has "--disable-simplexml".

Is it possible to use "emerge" package manager to enable this extension ?

Answer 1

You should reemerge php with the 'simplexml' USE flag set. It is on-by-default, so you probably will not have to do anything more than

emerge php -vua

In the case that the 'simplexml' USE flag is not set, add it to your USE= set in /etc/make.conf and then reemerge php using the above command.

Answer 2

You need to recompile PHP. Also see this comment on php.net

Btw. PHP 5.2 is wayy out of date, you should consider updating PHP.
