The first command you typed is also used to create an executable (by default a.out), since you did not provide the -c (compile only) or -a (create a library) flags. Change the first command to : ocamlc -o pascal -custom unix.cma pascal.ml -cclib -lunix to create the executable with the name 'pascal'. You could also have compiled pascal.ml : ocamlc -c pascal.ml (creates pascal.cmo and pascal.cmi) then you could have created an executable with the compiled file : ocamlc -o pascal -custom unix.cma -cclib -lunix pascal.cmo -- Maxence Guesdon ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
