ocamlopt on Windows doesn't produce executable

Question

Here's a simple OCaml program: helloworld.ml

print_string "Hello world...\n" ;;

I'm using OCaml 3.11.0 (MSVC built), VS 2008, and of course FlexDLL

Here's how I compile it (ran from the VS 2008 shell): ocamlopt helloworld.ml -o helloworld

No executable created. Is there something wrong? The program compiled and ran on Linux, though.

Answer 1

Show the full output from ocamlopt.

-o helloworld will produce binary helloworld (without extension).

If you want an .exe extension -- specify it explicitly

ocamlopt helloworld.ml -o helloworld.exe
