Description Pino Toscano 2019-08-05 10:35:03 UTC

Description of problem:
dune ships few OCaml libraries in addition to the tool itself; they are used to help with the interaction with C/system bits, as also briefly explained here:
https://dune.readthedocs.io/en/latest/configurator.html

I guess a ocaml-dune-devel is needed with the development bits, while the actual libraries shipped in ocaml-dune itself.

Version-Release number of selected component (if applicable):
ocaml-dune-1.7.3-1.fc30.x86_64

Comment 1 Richard W.M. Jones 2019-08-05 12:01:44 UTC

Which libraries are we missing exactly?  Can you show me an example program which
fails (eg to compile) with our dune package?  Just trying to get an idea of
how much work this involves.

(In reply to Richard W.M. Jones from comment #1)
> Which libraries are we missing exactly?

The whole Dune.Configurator, although I suspect it requires a bigger internal library.
For comparison, check the content of libdune-ocaml-dev in Debian:
https://packages.debian.org/sid/amd64/libdune-ocaml-dev/filelist

> Can you show me an example program which

One is mentioned in the Configuration documentation:
https://dune.readthedocs.io/en/latest/configurator.html
Another one is mentioned w.r.t use pkg-config for discover C dependencies:

Comment 3 Ben Rosser 2019-08-06 18:17:13 UTC

So the problem here is pretty simple: dune/jbuilder requires (or required-- it might be different now) opam-installer to install itself, which itself is *built* using dune/jbuilder.

Thus in the "install" section of the package, we install everything by hand. So when we wrote this originally, there were no libraries to install, and the spec was never updated to install them.

I think this should be pretty simple to fix. Will work at getting it working in Rawhide and then update the Fedora 30 package too.
