Using Captcha with Symfony2 (2.8)

I installed Captcha bundle using this following Instruction:

1. Add "gregwar/captcha-bundle": "1.0.0" to require section in composer.json
2. Run Windows PowerShell in root and call php composer.phar update
3. Console outputs

Warning: PHP Startup: Unable to load dynamic library 'C:\xampp\php\ext\php_yaml.dll' - Nie mo┐na odnalečŠ okreťlonego modu│u. in Unknown on line 0 Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files Incenteev\ParameterHandler\ScriptHandler::buildParameters Updating the "app/config/parameters.yml" file Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::buildBootstrap

Trying to install assets as relative symbolic links.

 Bundle Method / Error

! [NOTE] Some assets were installed via copy. If you make changes to these assets you have to run this command again.

[OK] All assets were successfully installed.

4. Following instruction I can skip this step

   // app/autoload.php $loader->registerNamspaces(array( // ... 'Gregwar' => __DIR__.'/../vendor/bundles', )); 

but my autoload.php files looks following:

use Doctrine\Common\Annotations\AnnotationRegistry; use Composer\Autoload\ClassLoader; error_reporting(error_reporting() & ~E_USER_DEPRECATED); $loader = require __DIR__.'/../vendor/autoload.php'; AnnotationRegistry::registerLoader(array($loader, 'loadClass')); return $loader; 

5. I enabled bundle:

   // app/appKernel.php public function registerBundles() { $bundles = array( // ... new Gregwar\CaptchaBundle\GregwarCaptchaBundle(), ); } 

6. Last instalation step is add gregwar_captcha: ~ to app/config/config.yml and it's done.

Now I'm trying to use it im my controller.

 public function registrationAction(Request $request) { $user = new Models\User(); $form = $this->createFormBuilder($user) ->add('username', 'Symfony\Component\Form\Extension\Core\Type\TextType') ->add('birth', 'Symfony\Component\Form\Extension\Core\Type\DateType') ->add('captcha', 'captcha') ->add('save', 'Symfony\Component\Form\Extension\Core\Type\SubmitType', array('label' => 'Register')) ->getForm(); $form->handleRequest($request); return $this->render( 'CassyW2Bundle:User:registration.html.twig', array( 'form' => $form->createView(), ) ); } 

I get error:

Compile Error: Declaration of Gregwar\CaptchaBundle\Type\CaptchaType::buildView() must be compatible with Symfony\Component\Form\FormTypeInterface::buildView(Symfony\Component\Form\FormView $view, Symfony\Component\Form\FormInterface $form, array $options) 

Where did I wrong?
