[Caml-list] ocamlfind on mingw: .exe extensions missing in findlib.conf

Dear Ocaml users,

I found that ocamlfind (findlib) builds fine for mingw on Cygwin, but it doesn't work. The issue is that the .exe extensions are missing in the findlib.conf file. This has the effect that most calls to ocamlfind end up in an error message like:

$ ocamlfind ocamlc
Uncaught exception: Unix.Unix_error(20, "create_process", "ocamlc.opt")

This is easy to fix with a text editor or sed. A more generic fix would be to use whereis/which/where to find ocamlc and friends but nothing is really satisfactory

$ whereis ocamlc.opt
ocamlc: /cygdrive/d/bin/ocamlmgw64/bin/ocamlc.exe

Finds ocamlc instead of omcalc.opt

$ which ocamlc.opt
/cygdrive/d/bin/ocamlmgw64/bin/ocamlc.opt

Doesn't show the extension

$ where ocamlc.opt
D:\bin\ocamlmgw64\bin\ocamlc.opt.exe

Works but is a windows command.

Does someone have an idea how to get the executable names in an elegant and platform independent way?

Best regards,

Michael
