Question

ocaml-base-compiler = 4.06.1 is in conflict with ocaml-bootstrap

Hello,

I am very interested in opam-bundle, to ship software to non ocaml users.
I tried to bundle a very simple software of mine: get_line, available in opam.

Is there a specific version of the OCaml compiler I should be using?

Here is how my trial went:

# opam switch
#  switch  compiler                    description
→  4.06.1  ocaml-base-compiler.4.06.1  4.06.1
# opam --version
2.0.0
# opam info opam-bundle

<><> opam-bundle: information on all versions <><><><><><><><><><><><><><><><><>
name                   opam-bundle
all-installed-versions 0.3 [4.06.1]
[...]
# opam-bundle get_line
No OCaml version selected, will use 4.06.1.
No environment specified, will use the following for package resolution (based
on the host system):
  - arch = "x86_64"
  - os = "linux"
  - os-distribution = "ubuntu"
  - os-version = "18.04"
  - os-family = "debian"

This looks like an opam message.
Should I be using a specific version of opam?

It seems the new ocaml-config package makes opam-bundle choke. I'll be running some tests and push an updated version tested on the latest opam release.

(as a workaround, in the meantime, a possibility would be to use the repository from before that was introduced, i.e. before commit c732ccaa from Nov. 2)

Even with an opam-repository from Nov 1, and after reinstalling all opam packages I was using, opam-bundle still give the same error.

Answer 5 · 2018-11-30T09:49:51.000Z

just to be sure, I probably wasn't very clear: the repository to change is the one used at opam-bundle runtime, not the one used to compile opam-bundle.

E.g. opam-bundle --repository='git+https://github.com/ocaml/opam-repository#c732ccaa'

I am making right now a new release that will work on the newer opam-repository, though, so you shouldn't have to worry about that.

Answer 6 · 2018-12-03T01:22:32.000Z

I sent a PR in opam-repository for the new release: ocaml/opam-repository#13072

Answer 7 · 2018-12-03T01:46:10.000Z

Thanks a lot for the new release, I could create a working opam-bundle.
The bundle was created on Linux but could install on a Mac; happy surprise.

Answer 8 · 2018-12-03T13:35:38.000Z

Nice to hear. opam-bundle normally resolves for the current system (you can change using cl flags), but will extract the actual OS requirements from the package informations once the bundle is resolved and print them.

I already filed a PR on friday, but yours got merged more quickly. As long as it's in there ¯_(ツ)_/¯ ... Thanks!

Answer 9 · 2018-12-04T02:50:32.000Z

Your PR was also merged I think. It improved the opam file of the package.
