Our base CGI language support on Deluxe and Premium Linux shared hosting includes the following:
Applications written in a compiled language such as C++ are not supported unless the applications are compiled specifically to run under the Linux operating system.
Our shared hosting accounts no longer support Ruby as of Jan. 23, 2014.
Note: Java support is only available on Classic Hosting accounts purchased before July 11, 2011, and only if they had Java enabled on that date and never disabled it.
