[Caml-list] Merlin issue with sedlex

Dear all,

I am running Merlin in order to code OCaml in emacs:

> The Merlin toolkit version 2.5.1, for Ocaml 4.04.0 (from shell)

Since today, I get a ton of error messages (that make coding nearly
impossible):

> Merlin failed with error: "Error: Error while running external
preprocessor Command line: /home/choeger/.opam/4.04.0/lib/sedlex
/./ppx_sedlex '/tmp/camlppxf365bd' '/tmp/camlppxc0ab4a' 1>/dev/null
2>/dev/null"

This file then seems to have the wrong version. I also find a file
/tmp/camlppx.lastfail:

> /tmp/camlppx.lastfail: OCaml abstract syntax tree implementation file
(Version 019)

Is this a known bug or do I have some problem with my setup?

Both sedlex and merlin seem up-to-date.

thanks in advance,

Christoph

Dear Christoph,

The released version of Merlin doesn’t support 4.04.0 yet (but I didn’t put the right constraints in opam file).
A new release is expected this week, in the meantime you can use the development version:

opam pin add merlin --dev-repo

Cheers,
Fred
