Symfony2 and HHVM Declaration of Doctrine\DBAL\Driver\PDOConnection::prepare() must be compatible

i am trying to set up a symfony2 project on a HHVM machine,

The HHVM is running on FastCGI as explained in the hhvm tutorial, thus running behind an apache2 server on Debian.

I have created everything but when i try to run my application i am getting the following error:

ContextErrorException: 16777217: Declaration of Doctrine\DBAL\Driver\PDOConnection::prepare() must be compatible with that of Doctrine\DBAL\Driver\Connection::prepare() in /LOCATION/shared/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php line 30

I am thinking this has something to do with PDO in HHVM but i tested it using the class_exists('PDO') and that says that PDO is enabled

Solution

  • This is an issue that was fixed via a pull request to the master branch of doctrine/dbal about 2 months ago. However, depending on the branch of Symfony 2 you are using, that doctrine/dbal fix may not be included.

    https://github.com/doctrine/dbal/pull/373

    If it is possible to use a version of Symfony 2 that includes this latest doctrine/dbal fix, I think you will see that issue go away.
