Subject: [Caml-list] opam switch recompilation with today's updates Reply-To: "David Allsopp" X-Loop: caml-list@inria.fr X-Sequence: 17114 Errors-to: caml-list-owner@inria.fr Precedence: list Precedence: bulk Sender: caml-list-request@inria.fr X-no-archive: yes List-Id: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: The ocaml package has been updated in opam-repository in PR12832*. Since all other packages depend on it, when you next run `opam update`, opam is going to want to rebuild all the packages in your switches. The compiler itself will not be rebuilt as part of this, "just" packages. The ocaml package is a virtual package which probes the configuration of the underlying OCaml compiler (either a system compiler, an opam-compiled OCaml, or an opam-compiled patched compiler). The reason for the change is to fix the creation of switches for compilers which don't support shared libraries. The problem was that a script in the ocaml package depended on the Unix library to probe the output of `ocamlc -where`. Sorry for the CPU-hogging inconvenience this will cause - it's a package we aim to leave alone most of the time! David * https://github.com/ocaml/opam-repository/pull/12832 -- Caml-list mailing list.
