 Compared to installation on GNU/Linux it's way more tedious to install V8Js

-The problem is that Google v8 requires (at least) Visual Studio 2013 as it
-uses certain C++11 features not available in Visual Studio 2012.
-
-Unfortunately the [PHP for Windows](http://windows.php.net/) project still
-relies on either Visual Studio 2012 or Visual Studio 2008.
-It supplies pre-compiled binary archives of required dependencies, however also
-compiled with Visual Studio 2008 and 2012 only.

-Since it is not compatible to link a v8 compiled with Visual Studio 2013 with
-a PHP interpreter compiled with Visual Studio 2012, you need to step up and
-compile PHP with Visual Studio 2013.  This requires to compile dependencies as
