DAViCal Dependencies
From Davical
All those dependencies must be met for DAViCal to function correctly. This page shall try to list the different depencies for different architectures.
Debian / Ubuntu
* A Webserver * postgresql * libyaml-perl * libdbd-pg-perl * libdbi-perl * php * php-pgsql * php-imap * php-curl * php-cgi * php-xml
For older PHP 5 installations, the PHP packages are different:
* php5 * php5-pgsql * php5-imap * php5-curl * php5-cgi
The Ubuntu 16.04 package unfortunately lacks the php-xml dependency, so this package has to be added manually.
