What is gccp? Did you mean gcc (or g++)? 127 is (usually) "command not found".

There's more options you'll need to pass as well - at least "-o" to specify
the name of the final executable (else it'll come out as "a.out" for historical
reasons).

Trying to compile code by executing shell commands through PHP is going to be
a total nightmare. It can be done but it's an incredibly awkward way to work.

Do you not have a shell login to the server, so you can run commands normally?

>(or what group should I be posting this in??)

A general Linux group most likely - comp.os.linux.misc ?
