charset=UTF-8 Content-Transfer-Encoding: quoted-printable Subject: Re: [Caml-list] Problems with conf-ncurses This is an issue with the opam metadata of the conf-ncurses package not knowing about your system. conf-* packages mark dependencies on libraries outside the OCaml ecosystem, and we manually indicate for each system the system-level packages that correspond to this dependency. You can see the current metadata for the conf-ncurses package with opam show --raw conf-ncurses or by visiting https://github.com/ocaml/opam-repository/blob/master/packages/conf-ncurse= s/conf-ncurses.1/opam To fix your issue, you could clone the opam-repository github repository, modify this metadata to add a "depexts" entry for your system (with the name of the ncurses-devel package on your distribution), and send the pull-request upstream. To know which name to use on your system, call (this may require running "opam install depext" if the depext plugin is not installed on your system) opam depext --flags My output is # Depexts flags detected on this system: x86_64 linux fedora so I use the "fedora" flag in the depext entry. Note: if you encounter further issues of this kind, the best place to report them would be https://github.com/ocaml/opam-repository/issues On Tue, Aug 30, 2016 at 10:36 AM, Leonardo Laguna Ruiz w= rote: > Hi, > > I tried to install a few packages in one of my computers and they fail be= cause conf-ncurses fails to install.
