no, I compile over a copy in my localhost, upload later to server I readed the link, sounds some odd to use cgi scripts, but at least is a doc document, I understand is a server code security issue. I'll try thanks for the help PD: I want save the input in a file located in server by php code before call cgi, then read it in code and paste output mods in the same file or maybe another, is legal in server create new binary files in runtime mode? or at least modify already created ascii files ?
