I'm trying to get my script working via cgi instead of netcgi, and I now have: #!/usr/bin/ocamlrun ocaml #directory "/usr/lib/ocaml/3.08.3/cgi/";; #load "cgi.cma";; let () = let params = Cgi.parse_args () in Cgi.header "text/plain"; try match int_of_string (List.assoc "foo" params) with | 1 -> print_endline "Yes" | _ -> print_endline "No" with | Not_found -> print_endline "'foo' not found" | exn -> print_endline "Error parsing 'foo'";; When I run it, I get: root@inner-sanctum:~/public_html/ml# ./helloweb.ml Reference to undefined global `Netmime' What do I need to do next? If it's another package I need to install, what's a name aptitude will recognize or else what's a URL I can download from?
