Bug#933722: camlp4 is deprecated and almost dead upstream (and a key package)

[Stéphane Glondu <glondu@debian.org>]

Package: camlp4
Version: 4.05+1-2
Severity: important
User: debian-ocaml-maint@lists.debian.org
Usertags: ocaml-4.08-transition

Hello,

See https://github.com/ocaml/camlp4/blob/trunk/README.md

At the moment, there is no version of camlp4 working with OCaml
4.08.0. Upstream suggests moving to ppx or camlp5.

There are currently 62 packages build-depending on camlp4.

Moreover, it is a key package because:

 - lwt build-depends camlp4
 - ocaml-ctypes build-depends liblwt-ocaml-dev
 - llvm-toolchain-7 build-depends libctypes-ocaml-dev
 - llvm-toolchain-7 is key because of popcon

[1] https://udd.debian.org/cgi-bin/key_packages.yaml.cgi

My first goal is to manage to get camlp4 out of the key package set.


Cheers,

-- 
Stéphane
