On ArchLinux php 5.4.14-1 I had to uncomment the line

extension=gmp.so

in /etc/php/php.ini file.

Probably, restart of web server (e.g. Apache) is required if working from web.

On Debian platforms, make sure you install the gmp development library first:

    sudo apt-get install libgmp-dev

Just like other extensions, you need the libs installed before php compile will gracefully complete.

on ubuntu you can get it from Synaptic Package Manager
just search words "gmp",you'll find it.

With PHP 5.3 on Windows, you need to use the VC9 build, otherwise you will not have the dll to enable GMP

Under Windows you will need to uncomment the line

;extension=php_gmp.dll

within the php.ini and restart Apache.

Note that this parameter requires a path, as in --with-gmp=DIR, if gmp is installed in a non-standard location, which is almost always the case when you are building your own PHP installation in your home directory.

Obvious, but it's an easy mistake.
