unknown flag `-unboxed-types` #1794

Closed Maelan closed 4 months ago

Maelan commented 4 months ago

Merlin annoyingly reports this flag as an error, although it is a perfectly legal compiler flag (and induces no change in OCaml syntax).

As soon as the dune file contains -unboxed-types (or its negation, -no-unboxed-types), I get spammed with this on every OCaml file I open (in my case, in Vim, with Merlin errors reported via the Syntastic plugin, which opens a disruptive error window whenever there is an error.)

Thanks for the report @Maelan. It's very surprising that a flag so old (sicne 4.04) is missing from our ignored_flags list and no one complained.

@xvw are you interested in doing the fix ? It should be quite straightforward: add a test that calls the errors command via merlin cli with these flags. It should show the error. Then add the flags to the ocaml_ignored_flags list to fix it.
