Installing V8js - dfryan/dreamfactory GitHub Wiki
In order to enable Javascript handlers for your DSP, you must install the V8js extension from PECL. At the time of this writing (March 2014), the current PECL extension does not compile and is not installable.
If you wish to enable server-side Javascript event handlers, you must compile and install an earlier version of the V8 library.
The following instructions are one way to get the PECL extension to install. It is assumed you have sudo rights and the necessary tools on your box to compile C/C++ programs. You should also be familiar with git but having it installed on your system works too.
Help with using git, and cloning the V8 library, is available in the repository's wiki.
In a nutshell, this is what needs to happen...
- Create a new, or change to a, directory where you can clone a repository.
- Clone the V8 repository and then we need to check out the tagged branch 3.15.5 which we've determined as working
- Make the dependencies target
- Make the native target
- Copy the include files and libraries to your system directories
Here's the command list for the entire process:

configuration option "php_ini" is not set to php.ini location
You should add "extension=v8js.so" to php.iniAt this point you've created the shared library for PHP called v8js.so. This file will be installed (by pecl) into the proper directory. Now you must either edit your php.ini file and add extension=v8js.so to the end or add a module extension file if your operating system has such things. For instance, in Ubuntu, you'd do this:
$ echo "extension=v8js.so" | sudo tee /etc/php5/mods-available/v8js.ini
$ sudo php5enmod v8js
$ sudo service apache2 restartRestarting apache is a good plan as well.
To check if V8js is loaded, you can do this:
$ php -i | grep v8js
/etc/php5/cli/conf.d/20-v8js.ini,
v8js
v8js.flags => no value => no value
v8js.max_disposed_contexts => 25 => 25The fact that you get output validates that the extension is loaded and available.
Enjoy!
