title: How to install V8js on PHP5.5?
body: <p>I want to install the v8js extension for PHP5.5 on Ubuntu 12.04 but can't make it working.</p>
  
  <p>When I try to install the v8js extension version 0.2.0 (latest) with PECL, I have this message:</p>
  
  <blockquote>
    <p>configure: error: libv8 must be version 3.24.6 or greater
        ERROR: `/tmp/pear/temp/v8js/configure --with-v8js' failed</p>
  </blockquote>
  
  <p>If I try to install an old version, I have a compilation error. This message is very similar to my issue: <a href="https://stackoverflow.com/questions/20982952/install-v8js-for-php-on-ubuntu">Install v8js for php on ubuntu</a></p>
  
  <p>How can I fix this issue?</p>
  
  <p>EDIT: I couldn't install it on Ubuntu 14.04 with PHP5.5, even with a PHP downgrade with PHPbrew to PHP 5.4. However, using Ubuntu 12.04 with PHP 5.4 works great. I didn't try the downgrade from PHP 5.5 to 5.4 on Ubuntu 12.04.</p>
