Enabling php-gd
From FrugalWiki
The gd library is installed by default, but it is not turned on. For its existence you can check with the command:
pacman -Qo /usr/lib/php/gd.so
which under solaria gives the following result:
php 5.2.6-2solaria1 is an owner of /usr/lib/php/gd.so
To enable the library just add a line
extension=gd.so
into your /etc/php.ini configuration file.
Once php.ini file has been modified, you must restart apache :
service httpd restart
