Hi, ocaml-dune does substitutions when building a project: https://dune.readthedocs.io/en/latest/usage.html#dune-subst
and unfortunately, it is based on the version control system, so tarballs obtained from a github release lack the necessary information for this to work. As a consequence, a package like elpi has to play sed tricks in its debian/rules to do this: https://salsa.debian.org/ocaml-team/elpi/-/blob/master/debian/rules?ref_type=heads and now, trying to update the elpi package, I get breakages because another file needs this trick (something I can fix... after much poking around!) and because other things aren't built correctly. For example, dune makes a META file which lacks the required "version = ..." line. So I'm writing to this list either to rally people on looking for a good solution or getting pointed to a fine manpage to read... Cheers, J.Puydt
