Ali Caglayan (Jul 19 2021 at 16:50): Ali Caglayan (Jul 19 2021 at 16:50):When I build with Makefile.dune I get this warning:
Warning 58 [no-cmx-file]: no cmx file was found in path for module Zarith_version, and its interface was not compiled with -opaque
How do we fix it?
Gaëtan Gilbert (Jul 19 2021 at 16:52):ocaml version, zarith version, dune version? how were they installed (opam?)?
Ali Caglayan (Jul 19 2021 at 16:53):zarith 1.12 Implements arithmetic and logical ope
dune 2.9.0 Fast, portable, and opinionated build
ocaml 4.12.0 The OCaml compiler (virtual package)
ocaml-option-flambda 1 Set OCaml to be compiled with flambda
all with opam
Gaëtan Gilbert (Jul 19 2021 at 16:55):is the warning located? what produces it?
Ali Caglayan (Jul 19 2021 at 16:58):This is where it appears in dune verbose:

So something is going on in plugins/micromega/numCompat.ml
Gaëtan Gilbert (Jul 19 2021 at 17:05):what does ocamlfind query zarith say and what files does the returned path contain?
Ali Caglayan (Jul 19 2021 at 17:06):/mnt/sdd1/.opam/dev/lib/zarith
Ali Caglayan (Jul 19 2021 at 17:06):which is correct

It only seems to happen when I have flambda enabled. See this related issue: https://github.com/ocaml/num/issues/9
Ali Caglayan (Jul 19 2021 at 17:41):I'm not sure why enabling flambda would give out extra warnings tho?
Emilio Jesús Gallego Arias (Jul 19 2021 at 18:12):That's a known issue, I suggest disabling the warning, it is quite harmless
Emilio Jesús Gallego Arias (Jul 19 2021 at 18:12):Indeed it is a flambda specific warning
