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
