See below for Gabriel's message to the Fedora list. Gabriel: thanks for kicking this off! I would appreciate being CCed in on this (or better, opam-devel if cross posting is ok), as I maintain the semi-official OPAM Fedora packages right now that point people to the OBS service.
In the interests of sanity, I'd rather not have two divergent sets of instructions for Coq users and the general OPAM population, so if we switch to Copr, then the official OPAM instructions should also switch. In the longer term, the packages will get into Fedora and everything will be fine, but don't forget that in the medium term that the Yum remotes will remain on people's computers for some time, and there's significant confusion in mixing up OBS and Copr packages. For Coq users right now, I think it's wiser to point them to the OPAM web pages which in turn point to my OBS repositories, rather than pointing them to Jon's. The reason is that mine are better tested, but they also use the bundled OCaml packages, whereas Jon's are upstream-friendly and break out the OPAM dependencies. There have been bugs from doing this in the past (e.g. with a libdose3 mismatch), so it's best to let this settle down upstream before pointing a large user base at a Copr remote that may still be a moving target. -Anil > >> From: Gabriel Scherer <[email protected] >> <mailto:[email protected]>> >> Date: 24 January 2015 11:14:39 GMT >> To: <[email protected] <mailto:[email protected]>>, Scott >> Logan <[email protected] <mailto:[email protected]>>, >> <[email protected] >> <mailto:[email protected]>> >> Subject: OPAM on fedora >> >> Hi all, >> >> I would like to update the page listing the state of OPAM packaging on Unix >> distributions >> https://github.com/ocaml/opam/wiki/Distributions >> <https://github.com/ocaml/opam/wiki/Distributions> >> with information for Fedora -- which is the distribution I'm using right now. >> >> As far as I understand: >> - neither opam nor aspcud are currently available as Fedora packages >> - there are separate copr repositories that work well in practice: >> opam: https://copr.fedoraproject.org/coprs/jonludlam/opam/builds/ >> <https://copr.fedoraproject.org/coprs/jonludlam/opam/builds/> >> aspcud: https://copr.fedoraproject.org/coprs/cottsay/gringo/builds/ >> <https://copr.fedoraproject.org/coprs/cottsay/gringo/builds/> >> >> (In previous discussion with Scott Logan I installed aspcud (which is needed >> in practice to have a functional opam) through his packages and that worked >> well.) >> >> Is it reasonable to advise end-users to install through the copr >> repositories?
