Original bug ID: 5238
Reporter: till
Assigned to: @damiendoligez
Status: closed (set by @damiendoligez on 2011-08-04T15:01:38Z)
Resolution: fixed
Priority: normal
Severity: minor
Target version: 4.00.0+dev
Category: ~DO NOT USE (was: OCaml general)
Has duplicate: #5277

Bug description

The default (i.e. empty) value for [Location.input_name] (in parsing) is "none". Several places assume it to be "" when it isn't set and will therefor try to load the file none.

$ echo "val run : unit -> unit" > test.mli
$ ocamlc -for-pack lib test.mli
$ ocamlc -pack test.cmi -o lib.cmo

Fatal error: exception Sys_error("none: No such file or directory")

Additional information

running this in ocamlopt yields:
Fatal error: exception Sys_error("lib.cmx: No such file or directory")
Which is linked but will require a different fix.

Your patch is a bit too naive: it gives error messages in the wrong format.
The problem is that the toplevel code needs different error messages.
I'll have to sort it out (and remove a lot of obsolete code), but not for 3.12.1.
