issues with compilation

[kbipinkumar]

i am trying to package pplacer for arch linux. as part of the process i followed instructions given here

while following the instruction initializing opam and installing dependencies i getting following error while adding repo as mentioned in the instruction

$ opam repo add pplacer-deps http://matsen.github.com/pplacer-opam-repository
$ opam update pplacer-deps
[ERROR] Could not update repository "pplacer-deps": OpamDownload.Download_fail(_, "curl: code 404 while downloading http://matsen.github.com/pplacer-opam-repository/index.tar.gz")
[ERROR] Initial repository fetch failed

looks like repository url has expired/deleted.

is it possible to fix it?

Edit: as a workaround i was able to create a local repo for pplacer-deps. However upon running cat opam-requirements.txt | xargs opam install -y i getting following error stating two modules failed to build

Hello-- for that specific error my guess is that you need to have an old version of GSL installed.

archlinux being a rolling release distro that could pose some issues

[kbipinkumar]

there is newer version of ocaml-gsl that builds with recent versions of gsl. however, ocaml-mcl cannot be built. it seems even Debian med project has given up on patching in ocaml binding for current releases of mcl

Description: add OCaml support
 Add OCaml support. This patch has been generated by taking the diff of an mcl
 clone that has implemented OCaml support and upstream's version of mcl 12-068,
 stripping out unnecessary changes and refreshing it over the Debian mcl packed
 version 14-137.
 .
 This patch is deactivated since it does not work any more.
