On an Ubuntu 16.04 VM with PHP 7.x, I am seeing the following error when enabling CiviCRM in Drupal 7:
ParseError: syntax error, unexpected 'clone' (T_CLONE), expecting identifier (T_STRING) or '(' in require_once() (line 1 of /home/westernfriend/public_html/sites/all/modules/civicrm/packages/DB/DataObject.php(207) : eval()'d code).
Is this due to incompatibility with PHP 7, a missing dependency, or perhaps something else?
