Hi,

On one of my servers that is running PHP 5.3.3-7, since the commit d345993ecb, I get the following error :

Fatal error:  Can't inherit abstract function Symfony\Component\HttpKernel\Log\LoggerInterface::alert() (previously declared abstract in Psr\Log\LoggerInterface) in /var/www/tracker.primoapp.fr/releases/20130107094001/vendor/symfony/symfony/src/Symfony/Bridge/Monolog/Logger.php on line 23

I don't get the error on my local server (running PHP 5.3.10-1) so I guess that it is linked to a PHP issue. Could you tell me if there is any workaround or if I really have to upgrade my PHP version.

Thanks for your help,
Arnaud

use the released version of Monolog with Symfony currently (all symfony branches have updated the composer constraints already). Monolog master now implements PSR-3, which requires an update of the Symfony interface to avoid conflicts
