[Caml-list] OcamlMakefile not working for me...

[Michael Leary]

There must be something simple I'm not doing...

"cgi.cmxa" and the LIBDIRS should appear on the "ocamlopt..." line (see below)

and if I try from the commandline, I get lots of other errors:

[0 leary@jean pleac]$ ocamlopt -c cgi.cmxa -I /usr/local/lib/ocaml/site-lib/netstring 19.1.ml

Bad build of ocaml?

OK, filenames can't be numbers.  :o}  One down.

OK, figured out the rest of it... I wasn't familar with the method for
using a package.  Roughly:

(* nineteen_one.ml *)
open Printf;;
open Cgi;;
parse_arguments default_config;
let value = argument_value("foo");;
header;;
printf "%s" value;;

# makefile
OCAMLMAKEFILE = ./OcamlMakefile
SOURCES = nineteen_one.ml
RESULT = nineteen_one
LIBS = str netstring
INCDIRS = /usr/local/lib/ocaml/site-lib/netstring
all: native-code
-include $(OCAMLMAKEFILE)

$> make nc
...

All good 'till now, but it doesn't run right:

$> ./nineteen_one
Fatal error: uncaught exception Failure("Cgi.parse_arguments: unknown method")


I tried:

try
	Cgi.parse_arguments default_config;
with x ->
	raise x;;


but that helped not at all... what other simple thing have I missed?  The
method is in the cgi.mli.

from cgi.mli:

val parse_arguments : config -> unit
val arguments : unit -> (string * argument) list
    (* - let () = parse_arguments config:
     * Decodes the CGI arguments. 'config' specifies limits and processing
     * hints; you can simply pass default_config (see below).


val default_config : config
    (* maximum_content_length = maxint

     * tmp_prefix = "cgi"

     *                 Work_around_backslash_bug;

This function expects the program to be called with the CGI interface;
when you call it directly on the command line, the Cgi module can't tell
what the CGI arguments are and which _HTTP_ method you use.

(Perl's CGI has something interesting for debugging: when the program is
called on the command line, the module asks the user for 'name=value'
bindings on the standard input; maybe this could be an useful feature
for Cgi)

This can't help for any problem at all: this construction catches the
exception and raises it again immediatly; except for the backtrace stack,
it is as if you did 'Cgi.parse_arguments default_config'.

Here's what I ended up with.  Works from the command line even, and
functions more or less like "errors to browser" in Perl.  In practice, I'd
probably do some matching on 'value', and Do The Right Thing, i.e. maybe
request user input ala CGI.pm, but this at least works.  :)

open Printf;;
open Cgi;;

let value =
	try
		parse_arguments default_config;
		argument_value("foo")
	with
		Not_found -> "key not found";
		| Failure x -> "Failure: " ^ x;;
	
header "text/html";;

printf "<html><body>foo: %s</body></html>" value;;

I've added it to the Wish List. That should be simple to implement.
