[Caml-list] Sys.getenv does not work under OS X?

[Alan Schmitt]

Hello,

I'm using OS X (Leopard, up to date), with ocaml 3.10.2 (compiled with
godi), and I was trying to use htmlc which fails for some reason. it
boils down to the following:

schmitta@charm compiler % echo $HOST
charm.inrialpes.fr
schmitta@charm compiler % ledit ocaml
Objective Caml version 3.10.2

# Sys.getenv "$HOST";;
Exception: Not_found.
# Sys.getenv "HOST";;
Exception: Not_found.

Is Sys.getenv supposed to work under OS X?

Thanks a lot,

Alan Schmitt

Sys.getenv "HOSTNAME"
?

Wrong

Should work

I'm guessing some special thing for HOST, since it work for HOME

Are you sure HOST is an environment variable, and not just a variable
that's set in your shell? You can use "printenv HOST" to check.

Thanks for all the answers, this is the problem. I don't know what
sets "HOST" but I had to export it to be able to access it.

Thanks again for helping me find the culprit.
