Bug#975894: Issues with dune 2.7.1

[Stéphane Glondu <glondu@debian.org>]

Hello,

After the update to dune 2.7.1 (from 2.7.0) in Debian, many packages
started to fail to build and I don't understand why.

Let's have a look at ocp-indent, for example:

  https://bugs.debian.org/975821

It fails with errors like 'Library "findlib" not found' or 'Library
"cmdliner" not found'. However, findlib and cmdliner are installed (as
shown by e.g. "ocamlfind query findlib"). Also, the issue does not seem
to be present in opam.

All this can be easily reproduced in an up-to-date Debian unstable chroot.

Does this ring a bell?


Cheers,
