You can find examples in the e= xamples/ directory (add.ml is a very
simpl= e one).  As for the specific example you desire, it is attached.<= br>It is maybe a bit more complex that you expected because it
demonstrates additional features (text escaping, setting the header,buffered output).

Hope it helps,
ChriS

The way it is, the script is NOT compiled, it is interpreted. I recommend you compile it to bytecode (http://caml.inria.fr/pub/docs/manual-ocaml/manual022.html) or native code (http://caml.inria.fr/pub/docs/manual-ocaml/manual025.html) however. > jonathan@inner-sanctum:~/csi/ml$ ocamlrun ocaml ./demo.ml > Cannot load required shared library dllpcre_stubs. > Reason: dllpcre_stubs.so: cannot open shared object file: No such file or > directory. I do not have that problem (get Debian :). Does the script run from the command line? Maybe setting the environment variable LD_LIBRARY_PATH can help? I propose to continue this conversation on the beginner mailing list (http://groups.yahoo.com/group/ocaml_beginners/) to which I also sent this message.

I propose to continue this conversation on the beginner mailing list
( http://groups.yahoo.com/group/ocaml_beginners/) to which I also sent
this message.

Sounds like a good idea; I'm waiting for my registration to be processed. In the meantime, I'd really like to have this working soon, and am having more trouble than I've had getting a first basic program working (in Python, Perl, Java, etc.), and be on to asking real questions instead of "How do I get this to run?"

At the moment I get:

jonathan@inner-sanctum:~/csi/ml$ !.
./demo.ml
Error while loading "/usr/lib/ocaml/3.08.3/netstring/netstring.cma": interface mismatch on Filename
Error while loading "/usr/lib/ocaml/3.08.3/netstring/netstring.cma": interface mismatch on Filename.
Preprocessor error

The segment of the script that I think is responsible for this is:

#directory "/usr/lib/ocaml/3.08.3/pcre";;
#load "pcre.cma";;
#directory "/usr/lib/ocaml/3.08.3";;
#load "unix.cma";;
#directory "/usr/lib/ocaml/3.08.3/netstring";;
#load "netstring.cma";;
#directory "/usr/lib/ocaml/3.08.3/cgi/";;
#load "netcgi.cma";;

The directory it's looking for netstring contains the following files (and many others):

jonathan@inner-sanctum:~/csi/ml$ ls /usr/lib/ocaml/3.08.3/netstring/|grep netstring
netstring.a
netstring.cma
netstring.cmxa
netstring_mt.cmi
netstring_mt.cmo
netstring_mt.cmx
netstring_mt.mli
netstring_mt.o
netstring_pcre.cmi
netstring_pcre.mli
netstring_str.cmi
netstring_str.mli
netstring_top.cmi
netstring_top.cmo
netstring_top.mli
jonathan@inner-sanctum:~/csi/ml$

What should I be doing next to get it to work?
